Nippon Shimpo's drill used in the previous deep drilling of the Antarctic ice sheet

Nippon Shinkan (Niiza City, Saitama Prefecture) has delivered high-precision aluminum tubes to the National Institute of Polar Research (NIPR) for their deep drilling of the Antarctic ice sheet. This is the first time in 17 years that Nippon Shintube has supplied aluminum tubes to the National Institute of Polar Research since 2002, when the company supplied them to the institute's 2003-2007 drilling project. According to the Polar Research Institute, the first drill is scheduled to be completed by the end of the year. In order not to collide with the rotary drill stored inside, a high degree of precision was achieved with a length of 5 meters and a bending accuracy of 0.3 mm or less. "There are no molds left. We had to redo everything, including the materials," said Takeo Kitazawa, general manager of the Technology Development Department, Safety & Environment Department, and Management Department.

    KM Biologics begins development of vaccine for novel coronavirus

    KM Biologics (Kita Ward, Kumamoto City) has started to develop a vaccine for a new coronavirus infection. At a press conference held on April 25, President Nagasato said, "Our strength lies in the fact that we have skilled technicians and facilities from our days at the Research Institute for Chemotherapy and Serotherapy (KAKETSUKEN). As a member of the Meiji Group, we will do our utmost to expand this business. The new drug will be developed jointly with the National Institute of Infectious Diseases, the Institute of Medical Science of the University of Tokyo, and the National Institute of Biomedical Innovation, Health and Nutrition. The company will consider using its Kikuchi Research Center in Kikuchi City, Kumamoto Prefecture, and its Koshi Plant in Koshi City, Kumamoto Prefecture, which are capable of producing vaccines for 57 million new influenza cases.

      Thermoelectric power generation module developed by NEDO and NIMS.

      The New Energy and Industrial Technology Development Organization (NEDO), the National Institute for Materials Science (NIMS), Aisin Seiki, and Ibaraki University announced on April 21 that they have developed a thermoelectric power generation module, which is composed of an alloy of easily available elements such as iron, aluminum, and silicon, and converts temperature differences into electricity. The company has developed a prototype communication device that incorporates the module, and confirmed that it can generate electricity and communicate with a temperature difference of 5 degrees Celsius. The temperature and humidity information was transmitted via Bluetooth, a short-range wireless communication standard, and was successfully displayed in real time on a tablet terminal screen.

        3D printer made by SLM Solutions, Germany

        Aichi Sangyo (Shinagawa-ku, Tokyo) and Shibaura Institute of Technology have started a joint research project to manufacture mass-produced products using metal 3D printers. Aichi Sangyo (Shinagawa, Tokyo) and Shibaura Institute of Technology have started a joint research project to manufacture mass-produced products using metal 3D printers. Overseas, mass production using metal 3D printers has already started, but in Japan, it is still in its infancy. In Japan, 3D printers are mostly used for prototyping and development, but not for mass production, because of the risk of internal problems during molding and the low accuracy of surface finish. Measurement and evaluation methods for processed materials have not been established in Japan. Therefore, through joint research, they will try to solve these problems.

          Kaken Seiko's new transfer equipment

          Kaken Seiko's new transfer equipment

          Kaken Seiko (Isehara City, Kanagawa Prefecture) has developed a new type of compact, single-bar transfer device that can be retrofitted to press machines. The company will start offering the product at the end of July. The price will be determined in the future. The company aims to sell 1,060 units a year. Three types of KTES series single-bar transfer machines will be available. The KTES series already uses the same method, but this time it uses linear servo motors. Depending on the stroke of each axis and the angle of motion assignment, the number of shots of the press machine can be increased from 50 to 75 per minute, which increases productivity. The manufacturer of the press machine to install this equipment is not required. First, we will introduce the 1200 mm wide x 1350 mm deep minimum x 180 mm high type. We will sequentially offer different types for different sizes of presses. Photo taken on June 6, 2019, location unknown, credit: Nikkan Kogyo Shimbun / Kyodo News Images
