Publication number: 20140174706Abstract: A thermal conductive stress relaxation structure is interposed between a high-temperature substance and a low-temperature substance to conduct heat in a heat-transfer direction from the high-temperature substance to the low-temperature substance. The structure includes an assembly configured such that a thermal conductive material gathers in a non-bonded state having stress relaxation effect. Such an assembly is a rolled-up body configured such that a carbon-based sheet material and a metal-based sheet material are alternately rolled up, for example. This structure has one or more interfaces at which adjacent parts can slide, thereby dividing a deformable region to relax the thermal stress. It has a low rigidity and can thus deform to release the thermal stress. The structure can suppress the thermal stresses and the shape changes that would be generated in the high-temperature substance and the low-temperature substance, and each physical body located there between.Type: ApplicationFiled: December 20, 2013Publication date: June 26, 2014Applicant: KABUSHIKI KAISHA TOYOTA CHUO KENKYUSHOInventors: Yuka YAMADA, Hiroshi HOHJO, Hidehiko KIMURA, Atsushi KAWAMOTO, Tadayoshi MATSUMORI, Tsuguo KONDOH, Hiroshi OSADA, Masanori USUI

Publication number: 20100235063Abstract: A hybrid vehicle (1) includes a rotation speed sensor (7) for detecting speed of rotation (Nm) of a motor generator (MG2). Fluctuation of the rotation speed (Nm) of the motor generator (MG2) reflects fluctuation of a first torque generated in a power transmitting member including a drive shaft (8). Hybrid vehicle (1) further includes a controller (30) for controlling a second torque transmitted from motor generator (MG2) through a rotation shaft of motor generator (MG2) to the power transmitting member, based on the speed of rotation (Nm) detected by rotation speed sensor (7). If the first torque is a vibration torque that fluctuates to cause the rotation shaft of motor generator (MG2) to rotate in positive and negative directions, controller (30) controls the second torque such that difference between absolute values of maximum value and minimum value of the vibration torque becomes smaller.Type: ApplicationFiled: January 13, 2009Publication date: September 16, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi Kawamoto, Masabumi Nishigaya

Publication number: 20060015015Abstract: A medical data warning notifying system and method for notifying a hospital only when there is abnormal data in medical data entered by a patient on peritoneal dialysis at home. In the medical data warning notifying system, a patient terminal used by a patient, a server for controlling data exchanged between the patient and a hospital, and a hospital terminal used by a doctor are interconnected over a network. The server receives medical data entered through the patient terminal, stores the received medical data, and judges from the received medical data whether or not there is any abnormal data. If it is judged that abnormal data is included, a warning signal is sent to the hospital terminal. A message created on the hospital terminal is relayed and sent to the patient terminal.Type: ApplicationFiled: July 14, 2003Publication date: January 19, 2006Inventors: Atsushi Kawamoto, Hidetomo Nakamoto, Eiichi Nishida
