Patent number: 9592986Abstract: A component supplying apparatus comprises a tape guide surface facing a lower surface of the carrier tape, a preceding tape contact part climbing onto a upper surface of the preceding carrier tape, and a subsequent tape blocking part configured to wait on the upstream side of the preceding tape contact part in a tape feeding direction while keeping a distance from the tape guide surface so as to enable the carrier tape to pass between the subsequent tape blocking part and the tape guide surface, and to move downwardly toward the preceding carrier tape when the preceding tape contact part is climbed onto the preceding carrier tape. The subsequent tape blocking part keeps the subsequent carrier tape waiting by contacting a front end of the subsequent carrier tape stacked on the preceding carrier tape onto which the preceding tape contact part climbs.Type: GrantFiled: July 2, 2014Date of Patent: March 14, 2017Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Minoru Kitani, Kazunori Kanai, Kazuo Kido, Seikou Abe, Motohiro Higuchi, Shigeru Matsukawa

Patent number: 8413322Abstract: An object of the present invention is to provide a component a mounting apparatus capable of accurately determining minute mounting applied pressure. The component mounting head of the component mounting apparatus includes: a movable part having a suction bit section and a movable shaft, a weight compensation mechanism for engaging with the movable shaft to compensate for the gravitational force of the total weight of the movable part and a component suctioned to the suction bit section, on the basis of the total weight; a force determination unit for determining a force applied to the movable part in the vertical direction; and a drive unit for moving the force determination unit in the vertical direction. The control unit of the component mounting apparatus controls the drive unit in such a manner that the determination value of the force determination unit becomes a target value.Type: GrantFiled: October 15, 2008Date of Patent: April 9, 2013Assignee: Panasonic CorporationInventors: Motohiro Higuchi, Ryoji Inutsuka

Patent number: 6675862Abstract: A blind apparatus comprises a drum on which a blind is wound, a motor for rotating the drum, an extrusion mechanism having a foldable arm for thrusting the leading end of the blind in a blind spreading direction with a spring force, a one-way clutch for transmitting the rotating force of the motor to the drum when the drum rotates in a blind take-up direction, a stopper for regulating a position of the arm at a spreading end position of the blind, and a circuit for detecting a motor lock current when taking up the blind. A stopping position in the spreading direction of the blind is detected by the position regulation of the arm by the stopper, and a stopping position in the take-up direction of the blind is detected by detecting the motor lock current. Thus, in a simple structure, the cost is reduced, and the operating sound is suppressed at the same time.Type: GrantFiled: December 27, 2001Date of Patent: January 13, 2004Assignees: Matsushita Electric Works, Ltd., NHK Spring Co., Ltd.Inventors: Ryogo Kobayashi, Motohiro Higuchi, Fusao Takanishi

Patent number: 4941608Abstract: A hot water supplying system is adapted to be connected to hot and cold water sources to mix the hot and cold water for discharging the mixed water. The system comprises a mixing chamber having a mixing valve movable therein to vary the mixing ratio of the hot water to the cold water, and a controller at which an intended water temperature is selected in accordance with a temperature scale provided thereat. The controller is operatively connected to the mixing valve so as to move the same into a proper position of discharging the water at the selected temperature. The mixing valve is given a temperature-responsive characteristic to be capable of self-adjusting its position independently of the controller in such a way as to adjust the water temperature in an open loop control manner at the start of discharging the water. An initial compensation mode is provided in the system to monitor the water temperature and determine a deviation between the monitored temperature and the selected temperature.Type: GrantFiled: December 11, 1989Date of Patent: July 17, 1990Assignee: Matsushita Electric Works, Ltd.Inventors: Tomoyuki Shimizu, Yoshikazu Taniguchi, Motohiro Higuchi, Masashi Suzuki
