Patent number: 12202318Abstract: An air conditioner for a vehicle includes a refrigeration cycle, a heating unit and a control unit. The refrigeration cycle includes an air-conditioning evaporator, a chilling evaporator, an air-conditioning side flow path, a detour flow path and an air-conditioning flow rate adjustment unit. The control unit includes a determination unit that determines whether a condensation condition is satisfied when a refrigerant is flowing through the chilling evaporator via the detour flow path in a state where an inflow of a refrigerant into the air-conditioning evaporator is prohibited. When the determination unit determines that the condensation condition is satisfied, the control unit controls the air-conditioning flow rate adjustment unit to allow an inflow of a refrigerant into the air-conditioning evaporator as a condensation suppression operation for suppressing condensation of a refrigerant in the air-conditioning evaporator.Type: GrantFiled: October 27, 2022Date of Patent: January 21, 2025Assignee: DENSO CORPORATIONInventors: Kouji Miura, Yoshiki Katoh, Masamichi Makihara, Atsushi Yamada, Kenta Kayano, Hiroaki Kawano, Tooru Okamura, Naoya Makimoto

Patent number: 10909007Abstract: Provided are a storage system and a storage control method wherein, when communication is disabled (communication via a data communication path is disabled) in spite of replacement of a second CTL among a first CTL and the second CTL that are redundant storage controllers and that are coupled via the data communication path, the first CTL executes a write process of writing dirty data and data management information to one or more storage devices while maintaining acceptance of I/O requests from a host. The replaced second CTL reads the data management information from the one or more storage devices. The first CTL stops accepting I/O requests from the host. The replaced second CTL starts accepting I/O requests from the host.Type: GrantFiled: March 24, 2017Date of Patent: February 2, 2021Assignee: HITACHI, LTD.Inventors: Naoya Okamura, Masanori Fujii, Naoki Moritoki

Patent number: 5908188Abstract: In an apparatus for feeding an original document, the time which is needed until the first original document is transported onto a transportation path after storing original documents is shortened. The original documents stacked on an original document supporting plate are successively supplied one by one in order from an uppermost original document. A discharged original document is steadily and easily inserted between the original document supporting plate and the original documents stacked on the original document supporting plate. When a hopper sensor detects that the original documents are stacked on the original document supporting plate, the original document supporting plate is moved upward until the upper surface of the uppermost one of the original documents contact a level sensor. At this stage, the original documents are supplied successively one by one from the uppermost original document by a paper feeding mechanism.Type: GrantFiled: September 15, 1997Date of Patent: June 1, 1999Assignee: Sharp Kabushiki KaishaInventors: Koji Katamoto, Yuji Okamoto, Naoya Okamura

Patent number: 5497984Abstract: A sheet post-processing apparatus is provided with a discharge tray which can be selectively moved between a processing mode position corresponding to a processing mode and a non-processing mode position corresponding to a non-processing mode. The apparatus is also provided with a control device which controls a tray drive unit which drives so as to set the discharge tray in the processing mode position when the processing mode is selected, while in the non-processing mode position when the non-processing mode is selected. The apparatus offers an improved discharging efficiency of processed sheets from a processing tray to the discharge tray in the processing mode and an improved aligning facility of sheets discharged on the discharge tray in the non-processing mode.Type: GrantFiled: July 15, 1994Date of Patent: March 12, 1996Assignee: Sharp Kabushiki KaishaInventors: Susumu Murakami, Naoya Okamura, Tomonori Ohata, Kazuya Hamaguchi, Koji Katamoto, Toshiya Mikita

Patent number: 5478061Abstract: A sheet post-processing apparatus is arranged such that in the non-staple mode, the leading edges of the sheets transported from the transport rollers are directed so as to be sandwiched between the upper and lower discharge rollers by a movable sheet guide in a non-staple mode position and the sheets are discharged onto a stacking tray through the upper and lower discharge rollers. In the staple mode, the leading edges of the sheets is directed to a discharge opening formed between the upper discharge roller and the movable sheet guide by the movable sheet guide in the staple mode position so as to be dropped onto the staple tray. After being processed by the stapler, the sheets are pushed by a pushing member through the discharge opening onto the stacking tray.Type: GrantFiled: July 1, 1994Date of Patent: December 26, 1995Assignee: Sharp Kabushiki KaishaInventors: Susumu Murakami, Toshiya Mikita, Koji Katamoto, Naoya Okamura, Tomonori Ohata, Kazuya Hamaguchi
