Patent number: 10452530Abstract: It is an object to provide a technique that can enhance data rewriting tolerance. An information processing apparatus includes a first nonvolatile memory and a second nonvolatile memory. The first nonvolatile memory stores first data. The second nonvolatile memory stores second data that is higher in update frequency than the first data. This allows the data rewriting tolerance in the device to be enhanced. For example, data of a dynamic map that is a dynamically changeable map can be applied to at least the second data among the first data and the second data.Type: GrantFiled: February 26, 2016Date of Patent: October 22, 2019Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Tetsuji Fujisaki, Yukio Kodama, Takehisa Mizuguchi, Masahiro Deguchi

Publication number: 20100113250Abstract: An ultra hard alloy is a hard material with a high degree of toughness. Small amounts of various materials are added to achieve these properties. One such material is vanadium carbide (VC). However, a crushed carbide raw material has a large grain size, meaning the properties of a product cannot be improved uniformly. Vanadium trioxide (V2O3) was substituted for a carbide as one of the structural raw materials for a material used in producing a tool such as a hob. Because vanadium trioxide is softer than vanadium carbide, it can be readily converted to fine grains in the ball mill mixing process performed during raw material preparation. As a result, the effects of the uniformly dispersed vanadium trioxide results in improved hardness for the sintered ultra hard alloy.Type: ApplicationFiled: July 28, 2008Publication date: May 6, 2010Applicant: MITSUBISHI HEAVY INDUSTRIES , LTD.Inventors: Hideo Tsunoda, Yoichi Tajitsu, Yukio Kodama, Taiji Kikuchi

Patent number: 6263111Abstract: A line buffer device temporarily stores a predetermined area of original image data which are divided into small blocks, each having a small area, so as to encode the image data for each block into data having a fixed length by a compression processor. The line buffer device is composed of a first-stage line buffer group and a second-stage line buffer group. The number of line buffers in the first-stage line buffer group is smaller by one than the number of lines constituting one block and the number of line buffers in the second-stage line buffer group is the same as the number of lines constituting one block. Encoding processing time is shortened and the circuit structure is simplified.Type: GrantFiled: November 18, 1998Date of Patent: July 17, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Narihiro Matoba, Masaru Ohnishi, Masaaki Tanioka, Yukio Kodama, Yoshifumi Imanaka, Hiroaki Furuta, Eisaku Tomita

Patent number: 5935269Abstract: When encoding data received by a dividing circuit and to be included in a CRC code word, the data is divided by a generator polynomial and remainder data resulting from the division is output from a plurality of parallel data output terminals of the dividing circuit. The remainder data is added to a CRC intrinsic value and "0" information in the adder to produce a sum. The sum is a CRC code for a CRC code word to be transmitted. When detecting code errors, data from a CRC code word is received by the dividing circuit, where the data is divided by the generator polynomial, and remainder data resulting from the division is output from the respective parallel data output terminals. The remainder data is added to the CRC intrinsic value and CRC code in the adder to produce a sum, and the sum is processed by a logical sum circuit to produce a logical sum output as a CRC flag.Type: GrantFiled: March 26, 1997Date of Patent: August 10, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yukio Kodama, Kazuo Murakami

Patent number: 5917841Abstract: A Cyclic Redundancy Check (CRC) code word except a fixed pattern is provided to a code data input terminal of a division circuit in synchronization with a clock signal and divided at the division circuit, then, a remainder data of the division result is outputted from output terminals. The remainder data outputted from the output terminals is compared with a CRC inherent value at a comparison circuit, and a comparison result signal indicating whether the CRC code word includes errors is outputted. A temporary memory means takes in the comparison result signal in response to rise of a clock signal inputted into a clock signal input terminal, temporarily stores it, then output its storage contents as an error detecting signal via an output node.Type: GrantFiled: November 8, 1996Date of Patent: June 29, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yukio Kodama, Kazuo Murakami
