    摘要: An engine exhaust gas recirculation system has an E.G.R. passage extending from an exhaust system of the engine to an intake system thereof downstream of an engine throttle valve. First and second E.G.R. control valves are provided at first and second points in the E.G.R. passage to control the exhaust gas-flow cross-sectional area of the E.G.R. passage at the first and second points, respectively. The first E.G.R. control valve is operatively connected to the throttle valve and disposed downstream of the second E.G.R. control valve. The intake air pressure upstream of the throttle valve is compared with the exhaust gas pressure between the first and second E.G.R. control valves to control the second E.G.R. control valve such that the exhaust gas pressure in the E.G.R. passage between the first and second E.G.R. control valves is made substantially equal to the air pressure in the engine intake system between the throttle valve and a venturi of a carburetor.

    摘要: A seat load measuring system for use in a vehicle occupant protection device for a vehicle seat has a zero point adjusting capability. The seat load measuring system comprises four weight sensor assemblies; a hub assembly for collecting the weight sensor outputs and providing an output determined by the weight sensor outputs; and means for communicating a user's desire for a zero point adjustment to each weight sensor assembly. Each weight sensor assembly includes a zero point adjusting section, which receives an output from the communication means for executing a zero point adjusting operation. If a zero point of a weight sensor assembly is not within a predetermined range, the zero point adjusting section may providing an alert. A zero point adjusting command may be entered by a command input device and passed to the zero point adjusting section. Alternatively, the zero point adjustment may be initiated through a momentary switch provided in the hub assembly.

    摘要: An airbag device 1 is composed of an inflator 2, a bag 3 and an electronic control unit (ECU) 4 created as a single unit as well as a pad 6 which is attached to the steering unit 5. There is connection from the ignition device 8 of the inflator 2 to the circuit board 18 by means of a connector 8a. The connector 8a realizes short-circuiting by means of external shorting member. In assembly operations of the airbag device, the shorting member can be easily removed to release the short-circuiting of the connector 8a. As a result, when attaching the airbag device to the ECU 4 the connector 8a does not occupy excessive space and there is no reduction in the assembly efficiency of the airbag device.

    摘要: An adiabatic intake insulator inserted into a portion for connecting a carburetor to a small two-cycle gasoline engine or the like in which the generation of cracks due to stress concentration when bolts are fastened are restrained and the looseness of the fastening member due to the shortage of fastening torque is prevented. The intake insulator comprises: portions for supporting and securing a carburetor; an intake passage through which air-fuel mixture from the carburetor is introduced to the engine; portions for securing the intake insulator to the engine each comprising a through hole for a bolt and a counterbore for accommodating a head of the bolt; and a channel formed on a circumference of a bottom of the counterbore.
