Patent number: 8549349Abstract: This storage controller includes a port unit and multiple processing units for inputting and outputting data to and from a storage apparatus. The port unit sorts the data I/O requests given from a host system to the corresponding processing units according to a table pre-defining the storage apparatus or a storage area in the storage apparatus to perform data I/O processing allocated to each of the processing units. The processing unit inputs data in the corresponding storage apparatus or the corresponding storage area according to the data I/O request sorted to itself from the port unit and, upon detecting a blockage of the other processing unit due to a failure, updates the table retained in each of the port units so as to sort the storage apparatuses or the storage areas allocated to the other processing unit to the remaining unblocked processing units.Type: GrantFiled: February 8, 2011Date of Patent: October 1, 2013Assignee: Hitachi, Ltd.Inventors: Atsushi Yuhara, Masao Nakano, Takao Sato, Kazunobu Ohashi, Takahiko Takeda

Patent number: 8375334Abstract: Predetermined travel locuss are set in a three-dimensional virtual space. Menu panels displaying menu items are arranged along the travel locuss assuming a display position set as a local origin so that the normal to each LCD panel will face a virtual camera. The transparency of a menu panel is raised in accordance with its distance to the virtual camera. A scroll operation moves menu panels along the travel locuss connecting display positions P until a selected specific menu panel reaches the display position P0. A display screen is drawn with the virtual camera and menu panels are three-dimensionally displayed in rolls. By sliding a stylus pen on the LCD panel, the menu screen displayed on the LCD panel scrolls at a velocity corresponding to the drag velocity. When the stylus pen is released from the LCD panel, an application program corresponding to the menu display entity (crosshatched) is activated.Type: GrantFiled: May 9, 2003Date of Patent: February 12, 2013Assignee: Kyocera CorporationInventors: Masao Nakano, Masao Nakazawa, Yoshio Sasaki, Eiji Takeuchi, Yosuke Miho, Hajime Ishikawa, Takeo Kobayashi, Tomoki Myoi, Hiroshi Kasakawa, Akiko Watanabe, Shinsuke Sato

Publication number: 20120131947Abstract: An object of the present invention is to provide a refrigeration cycle apparatus having a compressor that is not easily heated to high temperature by sliding heat and thus higher in reliability. Provided is a refrigeration cycle apparatus having a cost-effective compressor in the configuration in which a piston 9 eccentrically revolving, as driven by a shaft 4, is placed in a cylinder 6 and the circular terminal region 10a of a vane 10 partitioning the cylinder 6 into a suction chamber 12 and a compression chamber 13 is connected slidably to the external surface of the piston 9 in surface contact, which can reduce the sliding heat and is thus resistant to deterioration in reliability by reaction of the operating refrigerant.Type: ApplicationFiled: September 16, 2010Publication date: May 31, 2012Applicant: PANASONIC CORPORATIONInventors: Masao Nakano, Noboru Iida, Daisuke Funakoshi, Tsuyoshi Karino

Publication number: 20120128519Abstract: It was found that a refrigerant mainly containing a carbon-carbon double bond-containing hydrofluoroolefin has a function to suppress abrasive wear, compared to conventional HFC-based refrigerants, because the hydrofluoroolefin generates iron fluoride especially on the surface of the vane and piston, where sliding force is severe, from hydrogen fluoride, even if it is generated in reaction with water and oxygen. It is possible to reduce abrasive wear, by using a refrigerant containing as the base component a hydrofluoroolefin as operating refrigerant and a refrigeration oil 3 miscible with the refrigerant and a vane 10 made of a high-speed tool steel and sintered and quenched, because hydrogen fluoride generated by decomposition of the refrigerant in the region of a vane tip region 10a and a piston 9 peripheral surface, where sliding force is severe is converted to iron fluoride.Type: ApplicationFiled: August 18, 2010Publication date: May 24, 2012Applicant: PANASONIC CORPORATIONInventors: Masao Nakano, Noboru Iida, Tsuyoshi Karino

Publication number: 20120087822Abstract: A compressor, characterized in that a steel is used as the base material for the other sliding material vane 10 and nitrided, a CrN or DLC film is formed on the surface by PVD treatment, and a Ni-Cr-Mo cast iron is used for the other corresponding sliding material piston 9. It is possible in such a configuration to suppress the temperature rise by sliding friction of the sliding materials, such as the vane tip region 10a and the peripheral region of piston 9 that are vigorously slid, relax decomposition of the refrigerant, and suppress corrosion by hydrogen fluoride generated in reaction with water and oxygen, and thus to provide a compressor higher in reliability.Type: ApplicationFiled: June 16, 2010Publication date: April 12, 2012Applicant: PANASONIC CORPORATIONInventors: Masao Nakano, Noboru Iida, Tsuyoshi Karino
