    摘要: A digital filter circuit includes first and second counters which set and reset a latch circuit at predetermined counts. Clock pulses and the input signal are passed through a gate circuit to the first counter which outputs a set signal to the latch circuit only if the input signal is maintained at a high level for the predetermined count. Clock pulses and the inverted input signal are passed through a gate circuit to the second counter which outputs a reset signal to the latch circuit only if the input signal is maintained at a low level for the predetermined count. In this manner noise pulses on the input signal are filtered out of the output signal obtained from the latch circuit.

    摘要: A duty control circuit for controlling a duty factor in various industrial applications is proposed. It comprises a n-pulse counter, a m-pulse counter, another n-pulse counter, and a magnitude comparator. The magnitude comparator compares the count of the first counter with the count of the third counter and the duty control circuit gives a signal corresponding to ON when the former is larger than or equal to the latter and a signal corresponding to OFF when the former is smaller than the latter.

    摘要: After an output signal S4 is level-inverted, first and second shorting FETs 55, 56 as a level-inversion inhibiting circuit inhibit level-inversion so that the signal is maintained to the inverted state. Thereafter the inhibition of level-inversion is released, when the signal is subsequently level-inverted at a proper time according to a desired duty ratio of a PWM signal S1. Thus chattering can be prevented and thereby a PWM signal S1 of a stable duty ratio can be generated, even if the level of a reference signal S3 fluctuates due to a noise or the like during vehicle acceleration, for example.

    摘要: A parallel circuit 27 of a frequency control circuit 11 is provided as an external circuit. Thereby, the charging time t1 depends on the characteristics of the circuit elements, which are provided in the package of a semiconductor device 70 and therefore subject to manufacturing variations of the semiconductor device 70. The discharging time t2 depends on the parallel circuit 27, which is provided external to the semiconductor device 70 and therefore can be selected to have appropriate characteristics after the semiconductor device 70 has been manufactured. The circuit constants of circuits are set so that the discharging time t2 that depends on the device characteristics of the external parallel circuit 27 is longer than the charging time t1 that depends on the device characteristics of the internal circuits of the semiconductor device 70.

    摘要: In the power distributor using a semiconductor switching element, input terminals 10I and 10L, output terminals 12A-12J, connected to the element, and more preferably, the board terminals 30 and 32, are structured by a metallic plate, and arranged on the same plane perpendicular to the plate thickness. The metallic plate can be integrated by the resin mold, thereby the structure can be greatly simplified. The metallic plate can be produced by a greatly simple method by which, after the punching out of the metallic plate and the molding of the resin mold, a predetermined portion of the metallic plate is cut and the semiconductor switching element is mounted, and it can contribute to also the reduction of the cost.

    摘要: A method of and a device for detecting a pneumatic pressure drop of tires provided for a vehicle are disclosed. Rotational angular velocities of tires are determined and a judged value D is determined based on the determined rotational angular velocities. A speed of the vehicle, a front/rear acceleration FRA of the vehicle, a lateral acceleration LA of the vehicle and a turning radius R of the vehicle are substituted into a predetermined polynominal expression which is defined so that an influence of the turning radius R is exerted on all terms to determine a correction value. A judged value D' after correction is determined by correcting the judged value D using the correction value. It is judged whether a tire pressure drops or not, based on the judged value D' after correction. In such way, a tire pressure drop can be detected, accurately, excluding an influence of the turning radius R of the vehicle.
