Patent number: 8277750Abstract: Disclosed is a detector for chemical sensor devices, the detector being improved in detection sensitivity. Also disclosed is use of such a detector for chemical sensor devices. Specifically, disclosed is a detector for chemical sensor devices by which a substance to be measured is detected by adsorbing the substance contained in a medium on the surface thereof. The detector includes an adsorption layer containing hydroxyapatite or a substituted apatite obtained by substituting a part of elements in hydroxyapatite on a surface which is used for detecting the substance to be measured. Such a detector is greatly improved in detection sensitivity, and thus able to detect a very small amount of a chemical substance.Type: GrantFiled: August 30, 2005Date of Patent: October 2, 2012Assignee: Kinki UniversityInventors: Shigeki Hontsu, Masanobu Kusunoki, Hiroaki Nishikawa, Yoshiya Hashimoto, Izumi Yamada

Patent number: 6813703Abstract: An emulation system for data-driven processors aims at shortening the emulation time by employing parallel processing techniques without increasing overhead. The emulation system emulates virtual data-driven processors by using real data-driven processors. The emulation is performed by dividing the functionality of the processor into a data path and a timing path. In the data path emulation, each virtual packet to be processed in the virtual processor is expressed as a PACKET message, and the processing operation of the virtual packet is evaluated for each functional block. In the timing path emulation, a SEND signal and an ACK signal, to be controlled by a self-timed transfer control mechanism and a gate logic, are expressed as a SEND message and an ACK message, respectively, and stage-to-stage transfer operations of the SEND signal and the ACK signal are evaluated.Type: GrantFiled: January 24, 2003Date of Patent: November 2, 2004Assignee: Semiconductor Technology Academic Research CenterInventors: Hiroaki Nishikawa, Yasuhiro Wabiko, Ryosuke Kurebayashi, Shinya Ito
