Matsushita to sell vacuum cleaner that detects allergy-causing dust

OSAKA, Japan - Matsushita Electric Industrial Co. said April 4 it will put on sale on May 1 in Japan a new vacuum cleaner (in handout photo) that can detect and remove pollens, ticks and microscopic allergy-causing dust. The cleaner, aimed at consumers sensitive to dust, has a sensor that can detect dust as small as 20 micrometers, and it has an indicator that remains lit until such dust is fully vacuumed, the company said. The cleaner is expected to sell for around 65,000 yen.

Ikeuchi's backpack-type sterilization spray device "Dry Fog Hainou

The plant has improved its production efficiency by organizing work processes that had been scattered all over the place and setting up lines. The number of workers has also been increased by 40% from the current level. The company has been importing some parts from China, but the supply chain has been slow, so for the time being it will switch to parts made in Japan. The device sprays chemical solutions into a mist with a particle diameter of 10 micrometers or less (a micro is one-millionth). The particle diameter is so small that it does not get wet even if it hits an object. Since it is possible to spray the chemical solution while carrying it around, it can be used for sterilization in emergencies and in places where there is a blind spot.

A robotic hand developed by OMRON and the University of Tokyo that repeatedly performs precise insertion

Professor Masatoshi Ishikawa of the University of Tokyo and Omron have developed a robot hand that can perform precision work by groping at a speed of 1,000 times per second. When the ring hits the end of the cylinder and the angle shifts, the robot adjusts its three fingers to restore the shift. This is a high-speed reproduction of the way a human being searches for the right angle to fit a ring using the senses of his or her fingertips. In the past, even with the use of force sensors, it took time to process, and insertion and removal took 1-2 seconds. In the automation of precision assembly, it is difficult to keep the positional accuracy within 10 micrometers, including robots and jigs. If this can be handled by hand or control, the range of precision work will expand. Photo taken on November 27, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images

Kyodo Giken Chemical's Liquid Crystal Polymer Film

Liquid crystal polymer (LCP) film is expected to see a sharp increase in demand for 5th generation communication (5G) devices. LCP film is considered promising as a base material for flexible printed circuit boards (FPCs) due to its features such as low noise, low power consumption, and ultra miniaturization. Kyodo Giken Chemical (Tokorozawa City, Saitama Prefecture) is a small and medium-sized company that has started mass production. In the military industry, this is a matter of life and death. Because of this, Kyodo Giken began to receive a flood of inquiries about LCP, mainly from overseas companies. This is not the only strength of Kyodo Giken. LCP film is susceptible to lateral force and tears easily. This further suppresses noise, and the thickness of the copper foil can be reduced to 5 micrometers, making it possible to create ultra-fine circuit patterns.
