British media claimed that China "stealing the United States radar chip" to discredit China's space

“How did China's weapon thieves infiltrate into the US defense industry?” - Reuters published a long story on the subject on the 18th, detailing a story comparable to Hollywood blockbusters: US agents “fishing” on law enforcement, setting up bait. , cited in the US Chinese He Zhaohui "on the hook", want to "the United States radar chips shipped to China", and ultimately "the people get everything" will be arrested. The report said that because of the great care of US agents, 112 radar chips obtained by He Chaohui were “unknown”. “US officials strongly suspect that these chips are in China and may have been installed on satellites launched by China that fly around the earth.” In this regard, Peking University professor Zhu Feng told the Global Times on the 18th that western media frequently claimed that China “stolen US sensitive technologies” and accompanied it with China’s military strength. This reflected that some Americans and some Westerners have flowed sensitive technologies into China. Cup bow snake shadow mentality. “We don’t know how much water these statistics in the United States are, but this clearly reflects to a great extent the sensitivity and vulnerability of the United States to China’s rising mentality.”

Whenever there is a breakthrough in military or aerospace science and technology in China, the Western media will always publish “China steals Western military technology” articles “in a timely manner”. This time is no exception. Chang’e III successfully landed on the moon for a few days. Reports that have discredited the development of China’s space industry have emerged. “As Beijing narrows its military gap with the United States, Washington is faced with a major wave of smuggling of sensitive U.S. defense components and systems,” the Reuters article elaborated on such a story. In the spring of 2011, Aeroflex, an enterprise in Colorado, received an e-mail. The other person claimed to be “Philip Hope” from “Sella Electronic Instrument Co., Ltd.” of Oakland, Calif., to order two kinds of radar chips: one 112, One 200, with a total value of nearly $550,000, quickly paid the full amount by check. Aeroflex became suspicious and reported this to the Department of Homeland Security. The latter's preliminary investigation found that "Philip Hoppe" means He Chaohui, and "Sela Electronics Instrument Company" in Chinatown, Auckland City. “The US believes that these are chips purchased by others, a very rich person who cannot legally purchase the chip. This person may be in China, possibly China Aerospace Science and Technology Corporation, a state-owned company that bears almost all military civilian space projects in China. enterprise."

Reuters said that the order of the radar chip is "China's irreproachable technology," which is about the size of a one-cent coin and is a key component for maneuvering radar, guiding ballistic missiles, and protecting military hardware from nuclear radiation and solar radiation. The chip is not the most advanced in the US market and cannot control a sophisticated military radar alone. “But experts believe that, apart from being a radar component, this chip has very few other uses.” “The chip is legal in the United States for domestic trade and exports to friendly countries, but it is prohibited from exporting to rival countries — Iran, North Korea. And is considered to be America's biggest challenger in the future: China.” Worse still, Aeroflex is also suspected of illegal exports. The company acknowledged that it exported 14.5 million radar chips to China from 2003 to 2008, citing the lack of understanding of legal.

"This is a gamble. This is an opportunity to crack down on the entire Chinese smuggling syndicate. However, if He Chaohui successfully sends chips to China, it will certainly be extremely detrimental to the United States." Reuters said that after the trade-offs, the United States decided to "gamble." In July 2011, the United States agents disguised themselves as couriers and sent He Chaohui the first batch of 112 chips. They watched the installation of monitoring equipment in their homes and listed their names on the blacklist of the immigration management. Reuters said that because he did not deploy enough manpower to track He Zhaohui throughout the day, in September, he was discovered to fly from Tijuana, Mexico to China. However, US agents did not give up. In October, agents of the National Security Bureau disguised themselves as couriers and sent He Chaohui with the remaining 200 chips, but there was still no movement after two months. In the early hours of December 4, American agents secretly sneaked into the home of He Chaohui and found that the chip was no longer in the express box. On the 10th, US agents discovered that Ho Chao-hui had signs of "escape to China," and he took urgent action and arrested him when he "handed over the chips to the captain of a Chinese vessel."


Reuters said that according to information it has obtained, from October 2005 to October 2013, the U.S. government filed 280 court records on arms smuggling cases, of which 70 were related to Iran and 66 were related to China. The "Washington Post" claimed that a confidential report of the Pentagon Advisory Board this year stated that "Chinese hackers" have already obtained designs for more than 20 kinds of US weapons systems. However, the article commented that "China's stealing off-the-shelf components and weapons systems means a more direct challenge to the U.S. military." Reuters said, "It is difficult to estimate how many U.S. military technologies are acquired by China, because most of these transactions are The black market has proceeded; moreover, it is legal for many technologies to be exported to friendly countries, but a change of hands was sold to China."

Zhu Feng said in an interview with a reporter from the Global Times on the 18th that, in fact, the so-called “smuggling of sensitive technologies” in the United States is mostly a military-civilian dual-use technology and is not very sophisticated in the military. For this type of technology, China used to be in the past. On the occasions such as the US Strategic and Economic Dialogue, it is hoped that the United States will relax relevant export restrictions in order to ease the bilateral trade imbalance between China and the United States. The United States has also indicated that it is considering relaxing restrictions on China’s exports of related technology products, but ultimately no agreement has been reached. Not long ago, the United States also spared no effort to prevent NASA from cooperating with China. This is due to the public opinion environment in the United States. In the current environment of competition between China and the United States, scholars from all countries believe that China’s GDP will exceed that of the United States. The United States can now only hope to maintain its absolute military superiority against China. As long as such a public opinion environment exists, it will steal technology from the United States and the West. "The doubts and groundless accusations will continue.

Dumbwaiter Lifts

A dumbwaiter is a small freight elevator or lift intended to carry objects rather than people. Dumbwaiters found within modern structures, including both commercial, public and private buildings, are often connected between multiple floors. When installed in restaurants, schools, kindergartens, hospitals, retirement homes or in private homes, the lifts generally terminate in a kitchen.

The term seems to have been popularized in the United States in the 1840s, after the model of earlier "dumbwaiters" now known as serving trays and lazy Susans. The mechanical dumbwaiter was invented by George W. Cannon, a New York City inventor. Cannon first filed for the patent of a brake system (US Patent no. 260776) that could be used for a dumbwaiter on January 6, 1883. Cannon later filed for the patent on the mechanical dumbwaiter (US Patent No. 361268) on February 17, 1887.Cannon reportedly generated a vast amount of royalties from the dumbwaiter patents until his death in 1897.


A simple dumbwaiter is a movable frame in a shaft, dropped by a rope on a pulley, guided by rails; most dumbwaiters have a shaft, cart, and capacity smaller than those of passenger elevators, usually 45 to 450 kg (100 to 1000 lbs.) Before electric motors were added in the 1920s, dumbwaiters were controlled manually by ropes on pulleys.

Early 20th-century codes sometimes required fireproof dumbwaiter walls and self-closing fireproof doors and mention features such as buttons to control movement between floors and locks on doors preventing them from opening unless the cart is stopped at that floor. Dumbwaiter Lifts in London were extremely popular in the houses of the rich and privileged. Maids would use them to deliver laundry to the laundry room from different rooms in the house. They negated the need to carry handfuls of dirty washing through the house, saving time and preventing injury.

A legal complaint about a Manhattan restaurant's dumbwaiter in 1915, which also mentions that food orders are shouted up and down the shaft, describes its operation and limitations as follows:

[There is] ... great play between the cart of the dumb-waiter and the guides on which it runs, with the result that the running of the cart is accompanied by a loud noise. The rope which operates the cart of the dumb-waiter runs in a wheel with a very shallow groove, so that the rope is liable to and does at times slip off. ... The cart has no shock absorbers at the top, so that when it strikes the top of the shaft or wheel there is a loud report. ... [T]he ropes of the dumb-waiter strike such wall at frequent intervals with a loud report. ... [T]he dumb-waiter is often negligently operated, by running it faster than necessary, and by letting it go down with a sudden fall.

More recent dumbwaiters can be more sophisticated, using electric motors, automatic control systems, and custom freight containers of other kinds of elevators. Recently constructed book lifts in libraries and mail or other freight transports in office towers may be larger than many dumbwaiters in public restaurants and private homes, supporting loads as heavy as 450 kg (990lbs)
