Publication number: 20230283149Abstract: A stator for a rotating electrical machine includes a stator core, a stator winding disposed on or in the stator core, and an annular resinous seal which covers an axial end portion of a coil end of the stator winding. The resinous seal has an inner circumferential surface which is shaped to have a first inner diameter close to the stator core and a second inner diameter farther away from the stator core. The first inner diameter is selected to be smaller than the second inner diameter. This ensures the stability of electrical insulation of the stator winding.Type: ApplicationFiled: February 23, 2023Publication date: September 7, 2023Applicants: DENSO CORPORATION, AISIN CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keiji KONDO, Tatsuya FUJITA, Junichi SUGAWARA, Yoshihiro TAKAHARA

Publication number: 20230159289Abstract: A sheet feeding apparatus includes a sheet stacker, an air blower, a suction feeder, a lifting mechanism, an elevation detection sensor, an elevation detection sensor, a feed detection sensor, and processing circuitry. The air blower blows air to float an uppermost sheet of sheets stacked on the sheet stacker. The processing circuitry drives the lifting mechanism such that the sheet stacker is lifted by an elevation amount determined based on a sheet thickness of the sheets stacked on the sheet stacker, each time a sheet is detected when a number of sheets detected is smaller than a threshold number of sheets, and stops lifting of the sheet stacker until a sheet is not detected when the number of sheets reaches the threshold number of sheets, while repeatedly feeding the uppermost sheet and counting the number of sheets.Type: ApplicationFiled: October 27, 2022Publication date: May 25, 2023Applicant: Ricoh Company, Ltd.Inventors: Yohsuke Takamiya, Hidetoshi Kojima, Tatsuya Sugawara, Toshihiro Okutsu, Sachika Tamaki
