Publication number: 20230198066Abstract: A battery pack comprises a battery and a flexible printed circuit board (FPC) utilized to detect a voltage and a temperature of the battery. The FPC comprises a substrate having a front surface and a back surface, a thermistor which detects a temperature of the battery, temperature detection lines and voltage detection lines. The temperature detection lines are electrically connected to a thermistor and arranged between the back surface and the battery. The voltage detection lines are arranged on the front surface so as to overlap the temperature detection lines in a case that the FPC is observed in a plane view in a transmissive manner from a back surface to a front surface.Type: ApplicationFiled: February 21, 2023Publication date: June 22, 2023Applicant: DENSO CORPORATIONInventors: Takahiro MURAKAMI, Hironobu Kawashima, Hiromi Adachi, Takeshi Honda, Ryo Yamakawa, Hidemitsu Watanabe, Masahiro Sakakibara

Patent number: 6818708Abstract: The process for polymerizing olefins uses a plurality of series-connected polymerization reactors in which at least one of second and subsequent reactors is a vapor-phase polymerization reactor containing a multicomponent gas. The process comprises the steps of: taking the multicomponent gas out of the vapor-phase polymerization reactor; mixing the multicomponent gas with an inert gas which is lighter than at least one component of the multicomponent gas, thereby obtaining a mixed gas; compressing and/or cooling the mixed gas to liquefy a part of the multicomponent gas; discharging at least a part of a gaseous mixture comprising the inert gas and an unliquefied multicomponent gas out of a reaction system; and returning a fluid comprising the remainder of the gaseous mixture and the liquefied multicomponent gas to the vapor-phase polymerization reactor.Type: GrantFiled: September 18, 2002Date of Patent: November 16, 2004Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Hideki Satou, Shinji Araki, Hiromi Adachi
