Patent number: 9773562Abstract: A storage apparatus includes a flash memory that includes multiple blocks; and a control portion that reads data written in the block and writes the data into the block. The flash memory includes one block set having n pieces of the blocks including BR1 to BRn. A write data and a write flag are capable of being written into each of blocks BRi, the write data being written in accordance with a request, the write flag indicating that the write data has been written into a target block BRj. In accordance with a write request, the control portion performs an erasure process, a first write process, and a second write process. The erasure process erases the data including the write data and the write flag. The first write process writes the new write data into the block BRl. The second write process writes the write flag into a block BRm.Type: GrantFiled: May 29, 2015Date of Patent: September 26, 2017Assignee: DENSO CORPORATIONInventors: Takeshi Asai, Nobuya Uematsu, Tsuneo Yamamoto, Yasushi Kanda

Patent number: 9488907Abstract: In the chromium-containing material film of the present invention, an element is added thereto and is capable of bringing a mixture of the element and the chromium into a liquid phase at a temperature of 400° C. or lower. The use of such a chromium-containing material film as an optical film (e.g., a light-shielding film, an etching mask film, or an etching stopper film) of a photo mask blank can achieve an improvement in chlorine-dry etching while retaining the same optical characteristics and the like as those of the conventional chromium-containing material film, thereby increasing the patterning precision.Type: GrantFiled: January 8, 2015Date of Patent: November 8, 2016Assignee: Shin-Etsu Chemical Co., Ltd.Inventors: Hiroki Yoshikawa, Souichi Fukaya, Yukio Inazuki, Tsuneo Yamamoto, Hideo Nakagawa

Patent number: 9058883Abstract: To record data in a flash memory, upon detecting that a current destination memory block is full, a control apparatus records data in a destination memory block one block by one block, with “in-advance” data erasure of the next memory block and by determining if data erasure of the next memory block is successful. When data erasure of the next memory block fails, such memory block is designated as broken, and such memory block is excluded from a group of blocks to be used as recording destination. After determining the data erasure result of a yet-next memory block is successful, the required data is copied to the yet-next memory block. Therefore, even when one of the blocks is broken, a sequential data recording in the flash memory is performed without increasing the number of data copy operations between blocks.Type: GrantFiled: February 21, 2012Date of Patent: June 16, 2015Assignee: DENSO CORPORATIONInventors: Nobuya Uematsu, Tsuneo Yamamoto

Patent number: 6689515Abstract: A uniform thin phase-shifting photomask blank can be formed by depositing a thin film on a substrate by a reactive sputtering technique while passing, at least four times, the substrate over a sputtering target. In the formation of the blank, NO gas is used as the reactive gas, a target composed of a mixture of molybdenum and silicon is used as the sputtering target and a transparent substrate is used as the thin film-forming substrate to form, on the transparent substrate, a light-transmitting film capable of transmitting light rays having an intensity, which cannot substantially contribute to the exposure. In addition, the film is formed, on the substrate, through an opening having a sufficiently enlarged length along the substrate-conveying direction so that even regions whose deposition rate of the target component is not more than 90% of the maximum level thereof also contribute to the film-formation.Type: GrantFiled: March 15, 2001Date of Patent: February 10, 2004Assignees: Ulvac Coating Corporation, Mitsubishi Denki Kabushiki KaishaInventors: Nobuyuki Yoshioka, Akihiko Isao, Susumu Kawada, Tsuneo Yamamoto, Jun Amano, Ryoichi Kobayashi

Patent number: 6166351Abstract: In an air conditioning apparatus for a vehicle, plural electrical heating members are integrated with a heater core for heating air. The air conditioning apparatus includes a first control unit for determining number of the electrical heating members to be operated, and a second control unit for controlling electrical power supplied to each of the electrical heating members based on the number determined by the first control unit. The second control unit preferentially supplies electrical power to an electrical heating member plated at a side of a foot opening through which air blown toward a lower side of a passenger compartment. Thus, the lower side of the passenger compartment can be preferentially quickly heated by heat generated from the electrical heating members.Type: GrantFiled: November 10, 1999Date of Patent: December 26, 2000Assignee: Denso CorporationInventor: Tsuneo Yamamoto
