NTT's Transparent Rechargeable Battery

NTT's Transparent Rechargeable Battery

NTT has developed a "see-through rechargeable battery" (photo) that delivers about 50 times more power than conventional batteries. The average transmittance, which was previously about the same as that of sunglasses, has been tripled to 69%, equivalent to that of window glass. By gelatinizing the electrolyte, the average voltage was increased from 1.7 volts to 2.5 volts, which led to the improvement in transmittance. It also made it possible to deposit the film over a larger area, resulting in a larger battery. Six of the new batteries have the performance of one button battery. The company expects to use the new batteries for transparent signboards in tourist spots that post information without spoiling the scenery, windowpanes that can store electricity obtained from solar power generation, and lenses for smart glasses. In the future, the company aims to add flexible performance that can be bent. Photo taken on November 11, 2019, credit: Nikkan Kogyo Shimbun / Kyodo News Images

      Morix IC card with fingerprint authentication

      By downloading an application (application software) to a PC, smartphone or tablet terminal, users can send and receive crypto assets. The system is expected to be used with seven virtual currencies, including Bitcoin and Ethereum, and will also support ERC20-standard tokens in the future. President Kubota said, "We can improve the security by excluding identity theft. The company is also developing an IC card with a fingerprint authentication function without a battery as a payment card with a fingerprint authentication sensor for credit cards and other financial fields. The IC card has an electronic paper display on the upper right and a fingerprint sensor on the lower left.

        Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

        Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

        The established technology will be used for dry etching, thin film formation and cleaning of silicon. Easy-to-handle gases such as argon and nitrogen are irradiated onto solid fluoropolymers to generate fluorine-containing gas. The gas is then used for plasma treatment. Using a proto device with electrodes developed for special equipment, the company irradiated nitrogen gas and etched a glass substrate, and was able to etch 40 nanometers in one minute. The company plans to achieve an etching speed of 200 nanometers for commercialization. Plasma is an unstable state in which electrons have been removed from molecules, and it modifies the surface of materials, improving adhesion and cleaning effects.

            Osaka University's compact and lightweight flexible thermoelectric conversion device

            Osaka University's compact and lightweight flexible thermoelectric conversion device

            Associate Professor Toru Sugawara of the Institute of Scientific and Industrial Research, Osaka University, and Assistant Professor Kenzo Iwayano of the Graduate School of Engineering, Osaka University, and their colleagues have succeeded in reducing the size and weight of a flexible thermoelectric conversion device in which semiconductor chips are mountedon a flexible substrate. The new device converts the temperature difference between the two ends of the semiconductor into electrical information, and is equipped with a high density of about 200 ultra-small semiconductor chips per square centimeter, achieving high heat recovery efficiency and operational reliability. The flexible device, which was developed in 2018, has been improved. The new device uses semiconductor chips that are precisely aligned in size through ultra-fine processing that exceeds conventional methods.

              Maintenance of industrial robots installed at Daihen's customers' sites

              Daihen will start a service to realize maintenance of industrial robots installed at customers' sites via the Internet within the month. The service will appeal to small and medium-sized companies that are not familiar with handling robots. Daihen's IoT (Internet of Things) compatible FD19 robot controller is connected to the Internet (photo) to enable remote operation. This enables accurate confirmation of information that cannot be obtained by telephone inquiries alone, and is expected to reduce the burden of on-site response. There is no charge for using the maintenance service. In the future, the company plans to expand the service to overseas markets such as Southeast Asia, Europe, and the United States by utilizing the service centers it has established around the world.

                  Fuji Xerox Expands Maintenance and Inspection Operations with Smart Glasses

                  Fuji Xerox is expanding its maintenance and inspection operations for multifunction devices using smart glasses to wide format multifunction devices that print drawings and other documents. In April, Fuji Xerox started using smartglasses for commercial printing machines, with customer engineers (CEs) engaged in maintenance and inspection operations wearing the glasses. In the maintenance and inspection work that began in April in Japan, the company has been using the "Infomesh Visual Navigator," a remote work support solution using smart glasses from NTT Data Newson (Minato-ku, Tokyo). (Minato-ku, Tokyo), a remote work support solution using smart glasses. A total of 100 units of smart glasses have been installed. Therefore, accurate and prompt maintenance and inspection work is indispensable. The use of smart glasses has reduced the maintenance time by about 30% for long hours of work exceeding two hours.

                    legami's noise filter "ENEPLATE

                    legami's noise filter "ENEPLATE

                    This product is a compact noise filter that combines ferrite materials. It reduces harmonic currents flowing in the power supply line simply by retrofitting it near the wiring. An increasing number of companies are considering the introduction of this product as it prevents equipment malfunctions and helps to save electricity. Although it depends on the environment in which the system is installed, it is generally expected to save 10-15% of electricity when three of the main breakers are installed. "Mr. Higashi says, "By showing the amount of CO2 reduction, we have been able to get people to adopt the system positively. The company is aiming to further expand sales, taking advantage of the growing environmental awareness.

                      Hokuriku Electric Power's "Assist Arm" robot for power distribution work

                      Hokuriku Electric Power's "Assist Arm" robot for power distribution work

                      Hokuriku Electric Power Company has completed the development of the "Assist Arm" (photo), a robot for power distribution work, and has begun deploying it. The robot will assist in the construction work, which used to be done by two people in a high-altitude work truck, enabling the work to be done by one person. This is the first time such a robot has been used in Japan. The company plans to adopt 10 more robots, including those of group companies, by the end of fiscal year 2019. The robots will be used for the most frequent part of the power distribution work, the wire separator work. In the past, high-voltage wires were cut and the cut wires were connected to each other with a temporary equipment called a wire separator by lifting a stick-shaped tool weighing about 10 kilograms. The robot will be able to cut wires and grab objects with an arm that can move in six axes with a single control grip, saving labor.
