Patent number: 5737933Abstract: An absorption refrigerating machines-group apparatus that can be installed at reduced cost and prevent the occurrence of abnormal situations due to the unexpected suspension of the operation of a cooling water pump is provided. The absorption refrigerating machines-group apparatus according to the invention comprises a control panel 200 for issuing control signals, an adapter 300 having a control section 310 for relaying control signals and absorption refrigerating machines 100A, 100B, 100C having respective control sections 80, said control sections 310 and 80 being connected by a telecommunications line L51. When a signal for suspending the operation of the shared cooling water pump is relayed, the currently operating absorption refrigerating machines are brought into a temporary state that allows the operation of the cooling water pump P2 to be suspended through an exchange of signals between the control sections 310 and 80.Type: GrantFiled: July 9, 1996Date of Patent: April 14, 1998Assignee: Sanyo Electric Co., Ltd.Inventors: Nobuhiro Idei, Yasuo Sakata, Hideaki Oana, Yuichi Suzuki

Patent number: 5258681Abstract: A magnetic slot wedge inserted in each slot of a stator core of a dynamo-electric machine so as to close an opening of each slot for preventing coils embedded in each slot from getting out of each slot is disclosed. The slot wedge includes a first thin non-magnetic sheet such as a polyester film having the thickness of several ten microns or an aromatic aramid paper, an amorphous sheet bonded to one of two faces of the first non-magnetic sheet opposite the other face facing a coil side in the condition that the wedge is inserted in each slot, and a second thin non-magnetic sheet bonded to the amorphous sheet so as to cover it. Each non-magnetic sheet has such dimensions that each non-magnetic sheet is projected from both ends and both side edges of the amorphous sheet.Type: GrantFiled: March 25, 1993Date of Patent: November 2, 1993Assignee: Kabushiki Kaisha ToshibaInventors: Sadayoshi Hibino, Tadayuki Sato, Motoyasu Mochizuki, Tadatomo Kimura, Shigeo Ozawa, Takao Sawa, Yasuo Sakata

Patent number: 4806040Abstract: A ball and socket joint which allows the precise positioning of the line of contact between the ball and the socket utilizing a spherically curved socket and an offset radius ball. The significant manufacturing difficulties associated with the shaping of an offset radius socket is avoided by the use of the spherical socket and offset radius ball. Furthermore, the ball and socket configuration enables use of ceramic materials to produce the socket and/or ball components which, in turn, results in a dramatic increase of the life of the ball and socket joint.Type: GrantFiled: February 12, 1987Date of Patent: February 21, 1989Assignee: Cummins Engine Company, Inc.Inventors: Daniel E. Gill, Shigeo Suzuki, Yasuo Sakata

Patent number: 4553929Abstract: A heating furnace for heating elongate materials has a cylindrical furnace body whose both ends are closed by first and second end walls. The furnace body has an exhaust port formed near the first end wall. A material to be heated is inserted into the furnace body through penetrating holes formed in the end walls. A plurality of furnace core tubes are arranged in the body at a prescribed distance from the inner peripheral surface of the body and along the axis of the body. A heating chamber is defined by the inner surfaces of the core tubes. An air-gas passage is defined between the inner peripheral surface of the furnace body and the outer peripheral surfaces of the core tubes. The air-gas passage communicates with the heating chamber through a communication passage formed in the core tube adjacent to the second end wall.Type: GrantFiled: May 31, 1984Date of Patent: November 19, 1985Assignee: Kabushiki Kaisha ToshibaInventors: Tadayuki Kanatani, Yasuo Sakata
