Publication number: 20190017504Abstract: A screw pump includes a male screw, a female screw, a motor, a journal, a bearing member, and a case. The motor includes an output shaft, which transmits a torque to the male screw, and the motor is operable to drive the male screw to rotate the same through the output shaft. The journal is rotatably placed between the output shaft of the motor and the male screw. The bearing member rotatably supports the journal. The case includes a screw receiving hole that receives the male screw and the female screw. The journal and the male screw are coaxially and non-detachably integrated together. The output shaft and the journal are fitted together by clearance fit that enables transmission of the torque between the output shaft and the journal.Type: ApplicationFiled: January 13, 2017Publication date: January 17, 2019Inventors: Masashi INOUE, Yasuhiro TAKEUCHI, Haruo KAMIYA, Yusuke HONGO, Masahiro OKAJIMA

Patent number: 8469170Abstract: When a pulley and an armature are coupled with each other, first and second permanent magnets place the movable member at a location where a magnetic resistance of an attracting magnetic circuit, which generates an attracting magnetic force to couple between the pulley and the armature, is reduced. In contrast, when the pulley and the armature are decoupled from each other, the movable member is placed at a location where the magnetic resistance of the attracting magnetic circuit is increased, and a magnetic resistance of a non-attracting magnetic circuit is reduced. Thereby, a coupled state or a decoupled state of the pulley and the armature can be maintained without an erroneous operation.Type: GrantFiled: October 8, 2010Date of Patent: June 25, 2013Assignees: DENSO CORPORATION, Nippon Soken, Inc.Inventors: Yoshiharu Katano, Yousuke Yamagami, Motohiko Ueda, Yuichiro Okuda, Yasuhiro Takeuchi, Haruo Kamiya

Patent number: 7941972Abstract: A powered opening and closing system includes a door supported on a vehicle body, a motor, a drive mechanism for moving the door in opening and closing directions by virtue of power of the motor, an operation detecting sensor for detecting a handle operation when the door is operated to open or close, and a control circuit for prohibiting the operation of the drive mechanism when a predetermined operation prohibiting condition is detected. The drive mechanism brakes the movement of the door by putting the clutch in an engaged state while the motor is kept stopped. While the predetermined operation prohibiting condition is detected, the control circuit controls the clutch to be engaged while keeping the motor stopped when an opening of the door is detected, and controls the clutch to be disengaged when an operation of the handle is detected by the operation detection sensor.Type: GrantFiled: July 31, 2008Date of Patent: May 17, 2011Assignee: Mitsui Mining & Smelting Co., Ltd.Inventors: Haruo Kamiya, Kenichi Iijima
