Publication number: 20120048734Abstract: An analysis apparatus is provided with a storage tank, an injection nozzle, a syringe, a collection nozzle, a test sample tank, a microchip having two or more separation channels, detectors, a waste liquid tank, a controller, and a power supply. The collection nozzle collects a specimen which becomes a test sample from a test sample container housing the specimen, and transfers the specimen to the test sample tank. The separation channels separate characteristic components contained in the test sample. The injection nozzle is distanced from the collection nozzle and injects the test sample from the test sample tank into the separation channels. The detectors detect the separated characteristic components in the separation channels.Type: ApplicationFiled: August 25, 2011Publication date: March 1, 2012Applicant: ARKRAY, Inc.Inventors: Koji Sugiyama, Daisuke Matsumoto, Yasunori Shiraki, Satoshi Yonehara

Publication number: 20120035828Abstract: A drive control device for a vehicle is preferably used for controlling an internal combustion engine and/or a transmission, for example. A total fuel consumption amount calculating unit calculates total fuel consumption amount by integrating fuel consumption when the vehicle travels a unit distance at a predetermined vehicle speed and a predetermined acceleration, with respect to a time axis in accordance with a target distance. A traveling pattern calculating unit calculates a traveling pattern indicating a relationship between a vehicle speed and an acceleration when the vehicle travels the target distance, based on the total fuel consumption amount. By performing the control based on the calculated traveling pattern, it is possible to optimize the total fuel consumption amount. Therefore, it becomes possible to improve the actual fuel consumption.Type: ApplicationFiled: April 3, 2009Publication date: February 9, 2012Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Satoshi Yamanaka, Yoji Takanami, Tomoyuki Honda, Takayuki Amaya, Koji Sugiyama
