Patent number: 6456484Abstract: An electric double layer capacitor having an electrode rolled body contained in an outer packaging can. The electrode rolled body includes a positive electrode plate having a positive electrode foil, on both sides of which an active substance is applied, a negative electrode plate having a negative electrode foil, on both sides of which the active substance is applied, and a separator interposed between these electrode plates, and is obtained by winding the above parts. The negative electrode foil is electrically connected directly to a bottom of the outer packaging can so that heat generated in an interior of the electric double layer capacitor is efficiently transferred to the outer packaging can from the negative electode foil. The negative electrode foil has a greater thickness than that of the positive electrode foil, which is not electrically connected to the outer packaging can, so that heat quantity transferred is made large.Type: GrantFiled: August 22, 2000Date of Patent: September 24, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshiyuki Matsuoka, Kenji Matsumoto, Tomokazu Shohoji, Kentaro Shibuya, Yoshio Yamamoto

Patent number: 5845620Abstract: An ignition timing control system for an internal combustion engine that estimates the octane number of the fuel being used based on the state of engine combustion knocking and controls the ignition timing to a value not exceeding the knocking limit. The basic ignition timing is set along the knocking limit of fuel having least octane number and the maximum advance amount is set between the knocking limit and the second knocking limit of fuel having maximum octane number. Octane number is estimated from the occurrence of knocking. On the other hand, upper limit of the estimated octane number is set based on the MBT of the engine such that the estimated octane number is limited with the upper limit. Advance rate is determined based on the estimated octane number and is multiplied to the maximum advance amount to determine an ignition timing correction amount. The ignition timing is finally determined from the basic ignition timing and the ignition timing correction amount.Type: GrantFiled: December 30, 1994Date of Patent: December 8, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kotaro Miyashita, Shuichi Takagi, Yoshio Yamamoto, Yoshihisa Hara, Hiroshi Ikeba

Patent number: 5755303Abstract: A power transmitting mechanism for use in a hybrid vehicle includes first and second continuously variable transmissions connected to an output shaft of a vehicle's engine. The first continuously variable transmission causes left and right wheels to rotate via a starting clutch, differential gear and vehicle's axle. The second continuously variable transmission drives a generator/motor and also drives pulleys that are provided for actuating auxiliaries such as an air-conditioning compressor and power-steering compressor. In acceleration of the vehicle, the generator/motor operates as an electro motor so that the axle can be driven by a combination of the output power of the engine and generator/motor. In deceleration of the vehicle, the generator/motor operates as a power generator so as to effectively collect, from the axle, decreasing energy of the vehicle.Type: GrantFiled: November 19, 1996Date of Patent: May 26, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yoshio Yamamoto, Katsuyoshi Chubachi

Patent number: 5722359Abstract: An apparatus for controlling a motor vehicle equipped with a lean-burn engine and an electric motor coupled to an output shaft of the lean-burn engine has an engine controller, a combustion-pressure variation detector, and a motor controller. The engine controller controls the lean-burn engine to operate in a lean range of air-fuel ratios. The combustion-pressure variation detector detects a variation in a combustion pressure of the lean-burn engine controlled by the engine controller. The motor controller controls the electric motor to apply a force to the output shaft of the lean-burn engine for suppressing a variation caused in a torque produced by the lean-burn engine based on the variation in the combustion pressure as detected by the combustion-pressure variation detector means if the variation in the combustion pressure is in excess of a predetermined value.Type: GrantFiled: January 10, 1997Date of Patent: March 3, 1998Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Katsuyoshi Chubachi, Yoshio Yamamoto

Patent number: 5588414Abstract: A circular metal clinch ring (36) secures a cap (26) to a shell (24) of an EEGR valve (20). The clinch ring has a plurality of integral sharp pointed barbs (210) that partially embed in polymeric material of the cap. The ring constrains the shell and cap against relative axial and circumferential movement, with some barbs being pointed in one sense and others in the opposite sense to resist relative circumferential movement between the cap and the shell in both circumferential senses. A wave spring washer (186) is disposed to maintain the axial position of the bobbin-mounted solenoid coil (70) within the valve.Type: GrantFiled: August 29, 1995Date of Patent: December 31, 1996Assignees: Siemens Electric Limited, Honda Giken Kogyo Kabushiki KaishaInventors: Bernard J.
