Patent number: 11735752Abstract: In a fuel cell system, a first rubber seal is interposed between a top part of a first seal bead portion that is formed to protrude toward a first separator main body, and a membrane electrode assembly member. A method of low temperature starting of the fuel cell system includes: a warm-up step of warming up a fuel cell stack by introducing an oxygen containing gas discharged from a compressor, into a case interior space in a state in which a temperature of the oxygen containing gas is raised by causing the oxygen containing gas to flow through a pressure loss member; and an electrical power generating step of initiating generation of electrical power after completion of the warm-up step.Type: GrantFiled: February 10, 2022Date of Patent: August 22, 2023Assignee: Honda Motor Co., Ltd.Inventors: Kazuyoshi Miyajima, Naoki Imai

Patent number: 11473697Abstract: A flow rate adjusting device of the present invention includes a flow channel member and a valve mechanism. The valve mechanism includes a rod, a knob and a lock mechanism. The lock mechanism is switched by the knob moving in the traverse direction between a prohibited state in which the engaging portion is engaged with the to-be-engaged portion so that the rotation of the rod relative to the flow channel member is prohibited via the knob and a permitted state in which the engagement between the engaging portion and the to-be-engaged portion is undone so that the rod is permitted to rotate relative to the flow channel member.Type: GrantFiled: February 17, 2021Date of Patent: October 18, 2022Assignee: NABTESCO CORPORATIONInventors: Masayuki Ueno, Tadashi Fujii, Nichiki Okada, Naoki Imai, Shinsuke Uchida, Ikuo Makihira

Patent number: 11097636Abstract: A fuel cell vehicle includes a fuel cell, an oxygen-containing gas supply apparatus, and an ECU. A pump of the oxygen-containing gas supply apparatus is a shaft floating type air pump having a rotatable element. The rotatable element floats from a wall around the rotatable element, as a result of rotation of the rotatable element. The ECU includes a travel permission determination instruction unit. The travel permission determination instruction unit determines whether or not a predetermined condition indicative of a floating state of the rotatable element is satisfied, and if the predetermined condition is satisfied, permits traveling of the fuel cell vehicle, and if the predetermined condition is not satisfied, restricts traveling of the fuel cell vehicle.Type: GrantFiled: February 28, 2019Date of Patent: August 24, 2021Assignee: HONDA MOTOR CO., LTD.Inventors: Ryoji Sakai, Akihiro Matsui, Naoki Imai, Tatsuya Sugawara

Patent number: 9997191Abstract: A library manager to determine a relay-point library string when a particular cartridge (specific cartridge) is moved to an empty drive (target drive) for mounting. A method for determining a relay-point library string includes: receiving a command to mount a cartridge in a library string located on one side of the relay-point library string; searching for the target drive among library strings, and finding the target drive in a library string on the other side of an interposed relay-point library string relative to the library string in which the specific cartridge is located; selecting a relay-point library string based on predetermined conditions to move the specific cartridge using shuttle connections to the found target drive; and searching to determine whether or there is a newly available drive in a relay-point library string other than the selected relay-point library string before the selected cartridge reaches the selected relay-point library string.Type: GrantFiled: April 28, 2016Date of Patent: June 12, 2018Assignee: International Business Machines CorporationInventors: Naoki Imai, Takamasa Hirata, Masanori Kamiya, Norie Iwasaki
