Publication number: 20130308230Abstract: A charging device for a battery of a vehicle includes an insulation resistance detecting circuit, a charging circuit, a leak current detecting circuit and a decoupling circuit. The insulation resistance detecting circuit includes a coupling capacitor, and is disposed between the battery and a vehicle body for detecting an insulation resistance between the battery and the vehicle body. The charging circuit converts an alternating current supplied from an alternating current source into a direct current and charges the battery in a state without insulting the input terminal and the output terminal and in a state where the vehicle body is coupled to an earth. The leak current detecting circuit detects a leak current between the charging circuit and the earth. The decoupling circuit decouples the insulation resistance detecting circuit from one of the battery and the vehicle body during a charging of the battery.Type: ApplicationFiled: May 21, 2013Publication date: November 21, 2013Applicant: DENSO CORPORATIONInventors: Shinji ANDO, Seiji IYASU, Sadahisa ONIMARU, Kazuyoshi OBAYASHI

Publication number: 20070196484Abstract: Even when being released in a region from a lower small intestine to a large intestine with various coatings, bisacodyl is inadequately effective because of its hardness to dissolve due to its poor solubility, and thus a more drug should be contained. In the related art, there have been no techniques for allowing bisacodyl and dioctyl sodium sulfosuccinate to be simultaneously released in a region from a lower small intestine to a large intestine. A solid formulation having a core particle containing bisacodyl and dioctyl sodium sulfosuccinate coated with an enteric coating which allows the drugs to be released in a region from a lower small intestine to a large intestine can be used as an excellent pharmaceutical product.Type: ApplicationFiled: March 9, 2005Publication date: August 23, 2007Inventors: Kaoru Wada, Shinji Ando

Publication number: 20060284731Abstract: A passenger detection system has an antenna electrode and a guard electrode mounted to a seat bottom of a seat of a vehicle. The passenger detection system further has a power source means for detecting a presence of a passenger on the seat. The power source means applies electric power to the antenna electrode so that a load current flows in the antenna electrode and a weak electric field is generated from the antenna electrode by the load current. The power source means detects an electric current generated in the antenna electrode in response to the electric field. A capacitance between the antenna electrode and a floor of the vehicle is determined based on the detected electric current in a condition that an electric field generated from the antenna electrode on a side of the guard electrode is cancelled by the guard electrode, to thereby detect a passenger on the seat.Type: ApplicationFiled: June 14, 2006Publication date: December 21, 2006Applicants: DENSO Corporation, Nippon Soken, Inc.Inventors: Shinji Ando, Tsutomu Kamizono

Patent number: 6647812Abstract: A starter motor includes an intermediate gear engaging with and driven by a pinion connected to an output shaft of an electrical motor. The intermediate gear is coupled to the pinion by means of a retainer to be shifted in its axial direction together with the pinion. The intermediate gear engages with a ring gear of an engine to crank up the engine when it is shifted in the axial direction. The retainer is connected to a pinion boss by forcibly enlarging a resilient opening of its groove, and the resilient opening recovers its original position after the retainer is connected to the pinion boss. In this manner, the retainer is prevented from dropping off from the pinion boss during an assembling process of the starter motor. The retainer is made of resin to have an enough thickness to secure a sufficient mechanical strength.Type: GrantFiled: October 16, 2001Date of Patent: November 18, 2003Assignee: Denso CorporationInventors: Kuniaki Nito, Shinji Ando, Yasuyuki Wakahara
