Patent number: 9160329Abstract: A circuit control device controlling a switching circuit which has a semiconductor switching element, having a main controller, a drive signal output portion and an obtaining portion. The main controller outputs a drive control signal. The drive signal output portion receives the drive control signal and outputs a drive signal to the switching element, the switching element acting on the basis of the drive signal. The obtaining portion obtains circuit information on status of the switching circuit in synchronization with the drive control signal.Type: GrantFiled: January 14, 2014Date of Patent: October 13, 2015Assignee: DENSO CORPORATIONInventors: Yousuke Watanabe, Junichi Fukuta, Tsuneo Maebara

Patent number: 7903422Abstract: In a mobile terminal device, at least one heat conduction layer formed of a member, such as copper, aluminum or carbon, being excellent in heat conductivity is provided inside a circuit board on which electronic components are mounted. The heat generated in the electronic components is promptly dispersed in the direction of the face of the circuit board by the heat conduction layer, and transferred from the whole face of the circuit board to the operation member, such as keys, and the housing, and then radiated to the outside. With this structure, the local temperature rise at the operation member and the housing can be suppressed, and the temperature on the surface of the mobile terminal device can be made uniform, without significantly increasing the cost and the thickness of the mobile terminal device. In addition, high-performance electronic components can be used by adopting this structure.Type: GrantFiled: September 25, 2009Date of Patent: March 8, 2011Assignee: NEC CorporationInventor: Yousuke Watanabe
