摘要： In a motor control unit, a current-carrying failure detection unit determines a first determination condition and a second determination condition. The current-carrying failure detection unit measures a duration of a state where the first determination condition is satisfied, and a duration of a state where the second determination condition is satisfied. When the first or second duration exceeds a predetermined reference period, the current-carrying failure detection unit determines that a current-carrying failure has occurred.

摘要： A vehicle wheel bearing apparatus which reduces the weight, size and number of parts and also prevents ingress of rain water or dusts and leakage of differential gear oil has an axle housing supported under a body of a vehicle. A hollow drive shaft is inserted into the axle housing. A wheel bearing is arranged between the drive shaft and an opening of the axle housing and is structured as a unit including a wheel hub and a double row rolling bearing. The wheel bearing includes an inner member with a wheel hub integrally formed with a wheel mounting flange on one end and an axially extending cylindrical portion. At least one inner ring is press-fit onto the cylindrical portion of the wheel hub. The inner ring is formed with at least one of the inner raceway surfaces on its outer circumferential surface. An outer member is arranged around the inner member and formed with double row outer raceway surfaces on its inner circumferential surface opposite to the inner raceway surfaces. Double row rolling elements are arranged between the inner and outer raceway surfaces of the inner member and the outer member. A cage freely rollably holds the rolling elements. Seals seal an annular space between the inner member and the outer member. A cap, having a metal core formed from steel, is press-fit into an end of a central bore of the wheel hub.

摘要： A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member and an inner member with a wheel hub and at least one inner ring. Double row rolling elements are contained between the inner and outer raceway surfaces of the inner and outer members. A sensor holder, with a wheel speed sensor to detect the wheel speed, is mounted on the end of the outer member. An encoder is mounted on the inner ring and arranged opposite to the wheel speed sensor, via a predetermined air gap. The sensor holder has an annular ring shaped cover and a holding portion of synthetic resin. The wheel speed sensor is embedded in the holding portion. The cover is press-formed of an anti-corrosion steel sheet. The cover has a cylindrical fitting portion fit onto the end of the outer member. A flange portion extends from the fitting portion and is in close contact with the end face of the outer member. A bottom portion further extends radially inward from the flange portion. At least the outer circumference of the end of the outer member onto, where the cover is fit, is anti-corrosion treated.

摘要： In a voltage clamp circuit, a normally-on type field-effect transistor having a negative threshold voltage has a drain connected to an input node, a source connected to an output node and grounded via a resistance element, and a gate supplied with an output voltage of a variable direct-current power supply. When a voltage at the output node becomes higher than a clamping voltage because of voltage drop of the resistance element, the field-effect transistor is tuned off. Accordingly, the output voltage is limited to be at most the clamping voltage. Thus, a response speed is higher than those of conventional voltage clamp circuits using diodes or the like.
