Patent number: 7636924Abstract: A support frame for an optical disk unit where reduction in thickness and/or weight saving can be realized and the optical disk unit are intended to be obtained. In an optical disk drive unit, a support frame 2 has neither upper cover nor bottom cover, and is formed from a frame that continuously encloses both sides and a back of a disk tray 1 without any cutout portions in order to secure strength, and furthermore, the support frame 2 is manufactured by a die casting method using a metal material such as aluminum material, zinc material, and magnesium material, or by a press method using a metal sheet such as iron sheet, aluminum sheet, and magnesium sheet, or by composite molding using a polymer such as PPS (polyphenylenesulfide), POM (polyacetal), and LCP (liquid crystal polymer) with the metal sheet, or by a forging method using a metal material such as aluminum, thereby strength that prevents the optical disk drive unit as a whole from distorting or deforming during operation or actuation is secured.Type: GrantFiled: July 1, 2005Date of Patent: December 22, 2009Assignee: Panasonic CorporationInventors: Katsumi Ichinose, Masayuki Shiwa, Masatoshi Takeda

Patent number: 7058945Abstract: There is provided an information processing method which enhances the executing speed of a parallel processing computing device. A parallel processing block-forming step divides a program to be executed into a plurality of parallel processing blocks. A thread-forming step divides parallel processing blocks formed by the parallel processing block-forming step into a plurality of threads corresponding in number to the processors of a processor group. The processor group executes the threads generated by the thread-forming step. The instructing step instructs each of the processors to execute a thread of a next parallel processing block when it has terminated execution of a thread assigned thereto, and when a predetermined instruction is not given in the program.Type: GrantFiled: April 20, 2001Date of Patent: June 6, 2006Assignee: Fujitsu LimitedInventors: Katsumi Ichinose, Katsuyoshi Moriya

Patent number: 6725448Abstract: An optimizing system, method and computer readable recording medium to increase the speed of parallel processing by allowing a mixture of automatic creation of parallel processes and OpenMP API processing and to prevent reduction in performance during parallel processing by controlling the generation of wasted threads when automatic parallel processing and OpenMP API call each other. The optimizing system, method and recording medium create object code that creates parallel processes from a source program coded in a specific programming language, wherein the program is performed using a plurality of threads. The optimizing system generates object code for a source program which is executed in parallel by generating a plurality of threads.Type: GrantFiled: November 20, 2000Date of Patent: April 20, 2004Assignee: Fujitsu LimitedInventors: Katsuyoshi Moriya, Katsumi Ichinose
