Patent number: 10132941Abstract: A radiation detector includes a Peltier device (electronic cooling unit) for cooling a radiation detecting element, and a heat releasing part of the Peltier device is in thermal contact with a cold finger (thermally conductive part). The cold finger is made of a material with higher thermal conductivity than that of the base, and penetrates the base. The heat from the radiation detecting element is conducted from the heat releasing part of the Peltier device to the cold finger, and is dissipated to an area outside of the radiation detector through the cold finger. As such, heat is efficiently dissipated from the radiation detecting element.Type: GrantFiled: December 27, 2017Date of Patent: November 20, 2018Assignee: HORIBA, LTD.Inventors: Kengo Yasui, Kazutaka Okamoto, Shuji Takada

Publication number: 20140337584Abstract: A cache controller receives a reference request from a CPU executing a program in which information indicative of a reference request specifying in shared memory, an area not having an update request and information indicative of a snoop reference request are distinguished from one another. When the reference request specifying an area not having the update request is received, the cache controller acquires from the shared memory and without performing a snoop process, information stored in the specified area. The cache controller stores the information acquired from the shared memory to the cache memory of the CPU executing the program.Type: ApplicationFiled: July 25, 2014Publication date: November 13, 2014Applicant: Fujitsu LimitedInventors: Shuji TAKADA, Takatoshi FUKUDA

Patent number: 8859985Abstract: A radiation detector employed in a radiation detection apparatus and a fluorescent X-ray analyzer includes: a first circuit board on which a semiconductor radiation sensor is mounted and which is cooled by a Peltier device (an electronic cooling unit); and a second circuit board set apart from the first circuit board. A plurality of lead pins are joined to the second circuit board. Then, the first circuit board and the second circuit board are wire-bonded to each other. In comparison with conventional wire bonding performed onto the tips of lead pins, the work of connection is easy, the productivity is high, and the reliability of connection is high. Further, the second circuit board not requiring cooling is set apart so that cooling is concentrated on the first circuit board. This permits size reduction of the radiation detector.Type: GrantFiled: November 4, 2013Date of Patent: October 14, 2014Assignee: HORIBA, Ltd.Inventors: Kengo Yasui, Kazutaka Okamoto, Shuji Takada

Publication number: 20140297963Abstract: When an invalidation request is inputted from another processing device, a cache controller registers a set of an invalidation request address which the invalidation request has and an identifier of the other processing device which outputted the invalidation request in an invalidation history table. When a central processing unit attempts to read data at a first address not stored in a cache memory, if the first address is registered in the invalidation history table, the cache controller outputs a coherent read request containing the first address to the other processing device indicated by the identifier of the other processing device which outputted the invalidation request corresponding to the first address, or if the first address is not registered in the invalidation history table, the cache controller outputs a coherent read request containing the first address to all other processing devices.Type: ApplicationFiled: February 17, 2014Publication date: October 2, 2014Applicant: FUJITSU LIMITEDInventors: Takatoshi FUKUDA, Kenjiro MORI, Shuji TAKADA
