Patent number: 11978935Abstract: An apparatus/system for generating a high-purity nitrogen gas using a fuel cell includes; a fuel cell that operates by taking in air or a gas containing nitrogen and oxygen, and a fuel gas; a dehumidification mechanism that reduces moisture or water vapor content in an exhaust gas that is extracted from the fuel cell and has a lower oxygen concentration than air; and a filtering mechanism which includes a filter using fibers having different degrees of permeation for nitrogen and oxygen and converts the exhaust gas having a reduced moisture or water vapor content into a gas having an increased nitrogen concentration. The filter recovery ratio is higher when an oxygen concentration of a gas to be filtered is lower. The dehumidification mechanism is a pump unit including a water seal pump to provide an adiabatic expansion chamber in which the exhaust gas extracted from the fuel cell expands adiabatically.Type: GrantFiled: February 22, 2021Date of Patent: May 7, 2024Assignee: MICRO CONTROL SYSTEMS LTD.Inventors: Katsumichi Tagami, Soichi Hashiba, Takeshi Kitazawa, Noboru Fujii

Patent number: 11749675Abstract: Between a source electrode (25) of a main device (24) and a current sensing electrode (22) of a current detection device (21), a resistor for detecting current is connected. Dielectric withstand voltage of gate insulator (36) is larger than a product of the resistor and maximal current flowing through the current detection device (21) with reverse bias. A diffusion length of a p-body region (32) of the main device (24) is shorter than that of a p-body (31) of the current detection device (21). A curvature radius at an end portion of the p-body region (32) of the main device (24) is smaller than that of the p-body (31) of the current detection device (21). As a result, at the inverse bias, electric field at the end portion of the p-body region (32) of the main device (24) becomes stronger than that of the p-body region (31) of the current detection device (21). Consequently, avalanche breakdown tends to occur earlier in the main device 24 than the current detection device (21).Type: GrantFiled: January 7, 2021Date of Patent: September 5, 2023Assignees: FUJI ELECTRIC CO., LTD., DENSO CORPORATIONInventors: Seiji Momota, Hitoshi Abe, Takashi Shiigi, Takeshi Fujii, Koh Yoshikawa, Tetsutaro Imagawa, Masaki Koyama, Makoto Asai
