摘要： Throttles (10) include a bore (1b) defined within throttle body (1a). A longitudinal axis defined within the bore serves as a throttle air flow channel. Throttle shaft (3) extends across the air flow channel and is rotatably supported by the throttle body about a rotational axis. Throttle valve (5) is coupled to the throttle shaft and opens and closes the air flow channel by rotating throttle shaft and throttle valve within the bore. The throttle valve extends perpendicularly to the longitudinal axis of the bore when the throttle valve is disposed in a fully closed position. Clearance (S) is defined between a peripheral edge (5a) of throttle valve and an inner wall of the bore when the throttle valve is in the fully closed position. The peripheral edge of the throttle valve end defines a substantially spherical surface having a radius (R) of curvature with respect to the rotational axis.

摘要： In a PWM motor driving device, the amount of electric power supplied to a motor is controlled by controlling the ON/OFF duty factor of output transistors connected between a power source and the motor. This motor driving device has phase detecting means for detecting, among a plurality of phases of the motor, the phase which is currently being driven by the output transistors, and saturation preventing means for performing control according to the voltage of the phase detected by the phase detecting means in such a way that the output transistors are not saturated. Thus, the output transistors are controlled so as not to be saturated according to the voltage of, among the plurality of phases of the motor, the phase in which the motor is currently being driven by the output transistors. Thus, for example, when the upper output transistors are undergoing PWM switching, the lower output transistors are controlled so as not to be saturated no longer according to the voltage of the phase in which the motor is currently being driven by the upper output transistors as practiced conventionally. This helps obtain better motor rotation characteristics.

摘要： A sensorless motor driver receives the back electromotive forces appearing in the individual coils provided one for each phase in a brushless motor and the voltage at the node common to all of those coils, and produces square-wave signals including noise. These signals are then subjected to masking by a masking circuit in accordance with a noise masking signal produced by a masking signal producing circuit. In accordance with the thus masked signals, a driving current is supplied to the brushless motor. The driving current varies according to the load on the motor. The masking signal producing circuit monitors the driving current supplied to the motor, and outputs the masking signal in such a way that the length of the masking periods varies according to the driving current.

摘要： In rubber hoses for conveying fuels, the inner tube rubber layer coming into contact with fuels generally comprises two sublayers, namely the inside fluororubber layer coming into direct contact with fuels and the outside layer of an NBR and the like. The fluororubber layer is undesirably subject to degradation due to amine type additives contained in fuels and is poor in adhesion to the outside layer. In accordance with the invention, the contents of vinylidene fluoride, one of the fluororubber constituents, is reduced to 10-50 mole percent and at the same time a monomer capable of causing crosslinking of the fluororubber in the presence of a peroxide is newly added as a component of the fluororubber composition in a specified amount. The results are prevention of the degradation due to amine type additives and improved adhesion to the outside layer.
