Patent number: 8579748Abstract: An in-vehicle power transmission apparatus is equipped with a motor-generator working as an engine to drive a vehicle and a power split device made up of a plurality of power split rotors. A first one of the rotors is coupled to a driven wheel of the vehicle, while a second one of the rotors is coupled to an accessory such as an air compressor of an air conditioner. The speed of the second rotor is controllable independently of that of the driven wheel. This eases restrictions on the supply of power produced by the generator-motor to the accessory. Alternatively, the rotors are so linked that when the speed of the first rotor is not zero (0), the speed of the second rotor has one of zero (0) and a value other than zero (0), thus ensuring the stability in supplying the power to drive the vehicle to the accessory.Type: GrantFiled: April 21, 2010Date of Patent: November 12, 2013Assignee: Nippon Soken, Inc.Inventors: Koji Kawasaki, Takenori Matsue, Yuji Tokudome, Mitsuo Inagaki, Oyuki Ogawa

Publication number: 20100281901Abstract: In an air conditioner for a vehicle, in a heating operation for heating a vehicle compartment, when heating capacity is obtained by flowing a coolant through an inside of an indoor heat exchanger, the coolant flows directly in the inside of the indoor heat exchanger to heat air to be supplied to the vehicle compartment. In contrast, when the heating capacity is not obtained by flowing the coolant through the inside of the indoor heat exchanger, the coolant flows through a first water-refrigerant heat exchanger and a refrigerant in a heat pump cycle circulates so that heat of the coolant is absorbed by the refrigerant in the first water-refrigerant heat exchanger, and the air is heated in the indoor heat exchanger by using heat of the refrigerant that has absorbed the heat of the coolant.Type: ApplicationFiled: May 4, 2010Publication date: November 11, 2010Applicant: Nippon Soken, Inc.Inventors: Yasuhiro Kawase, Yukikatsu Ozaki, Mitsuo Inagaki

Publication number: 20080171623Abstract: A belt driven mechanism which may be employed to transmit engine torque to an automotive electric rotary accessory such as an alternator. The belt driven mechanism is equipped with bearings disposed between a pulley around which a belt is wound and a torque output rotor. The belt driven mechanism also includes a coil spring mechanism having a length with a first and a second end portion to establish transmission of torque between the pulley and the rotor. Each of the first and second end portion has a plurality of points of attachment to a corresponding one of the pulley and the rotor, thereby distributing a mechanical load acting on the pulley or the rotor into fractions. This avoids local exertion of the load on the bearings, thereby prolonging the service life and ensuring the reliability of operation of the bearings.Type: ApplicationFiled: January 8, 2008Publication date: July 17, 2008Applicants: NIPPON SOKEN, INC., DENSO CORPORATIONInventors: Tomoji Yamada, Mitsuo Inagaki, Koji Kondo

Patent number: 6802243Abstract: A swing member is supported by a swing support member like a universal joint of a Hook's type such that it can swing in a state where it is prevented from rotating around a center line. In this manner, even if a shaft rotates at high speed, the swing member is surely prevented from rotating around the shaft. Therefore, it is possible to prevent a piston from excessively vibrating, hence to prevent large noises from being made, and to improve reliability and durability of a compressor when the compressor is operated at high speed.Type: GrantFiled: October 16, 2001Date of Patent: October 12, 2004Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Mikio Matsuda, Mitsuo Inagaki, Shigeru Hisanaga, Naruhide Kimura

Patent number: 6742439Abstract: A variable displacement compressor includes a linking groove, which forms a hinge for connecting an arm and an inclining member. The groove is generally U-shaped (open). A link pin is fitted in the groove such that the link pin can pivot or slide within the groove. As a result, installation of a movable parts assembly, which is done by inserting the link pin into the groove, is easier. A controlled pressure chamber improves the response of the compressor to controls.Type: GrantFiled: May 22, 2002Date of Patent: June 1, 2004Assignees: Nippon Soken, Inc., Denso CorporationInventors: Mikio Matsuda, Naruhide Kimura, Mitsuo Inagaki, Shigeru Hisanaga

Patent number: 6543238Abstract: In a refrigerant cycle system, refrigerant compressed in a first compressor is cooled and condensed in a radiator, and refrigerant from the radiator branches into main-flow refrigerant and supplementary-flow refrigerant. The main-flow refrigerant is decompressed in an expansion unit while expansion energy of the main-flow refrigerant is converted to mechanical energy. Thus, the enthalpy of the main-flow refrigerant is reduced along an isentropic curve. Therefore, even when the pressure within the evaporator increases, refrigerating effect is prevented from being greatly reduced in the refrigerant cycle system. Further, refrigerant flowing into the radiator is compressed using the converted mechanical energy. Thus, coefficient of performance of the refrigerant cycle system is improved.Type: GrantFiled: June 26, 2001Date of Patent: April 8, 2003Assignees: DENSO Corporation, Nippon Soken, Inc.Inventors: Yasushi Yamanaka, Yasutaka Kuroda, Shin Nishida, Motohiro Yamaguchi, Yukikatsu Ozaki, Tadashi Hotta, Sadahisa Onimaru, Mitsuo Inagaki

Patent number: 6260766Abstract: A heating apparatus for a vehicle includes a pump for circulating cooling water in a cooling water circuit, a heating heat exchanger for heating air blown into a passenger compartment of the vehicle using cooling water as a heating source, and a throttle valve disposed at a discharge side of the pump. In the heating apparatus, when the temperature of cooling water is low and heating capacity for heating the passenger compartment is insufficient, an opening degree of the throttle valve is reduced by a control unit. Therefore, heat is generated from the throttle valve and the pump so that the temperature of cooling water is increased. Thus, heating capacity of the heating apparatus can be improved without using a manual operation.Type: GrantFiled: April 5, 1999Date of Patent: July 17, 2001Assignee: Denso CorporationInventors: Toshio Morikawa, Hajime Ito, Toshinao Aoki, Sadahisa Onimaru, Mitsuo Inagaki, Hirohito Matsui, Masaru Tsunokawa
