    摘要: A semiconductor switching element driving circuit comprises an overcurrent limiting circuit which instantaneously drops a voltage of a gate terminal of an IGBT when a main IGBT current becomes larger than a predetermined level i1. An overcurrent protection circuit which first decreases the main IGBT current at a first inclination when the main IGBT current becomes larger than the other level i2 lower than the i1 and then reduces the main IGBT current at a steep second inclination when it becomes smaller than another level i3.

    摘要: Detection of angles associated with wheel alignment of a vehicle can be carried out properly at all times according to the present wheel alignment examining apparatus irrespective of the size of a wheel to be examined. The present apparatus includes a sensor member (105, 106) pressed against a side surface of a wheel (11) to be examined and thus the sensor member rotates together with the wheel to be examined. Various inclination angles, such as toe, camber, caster and king pin angles, are detected from a displacement of the sensor member during its rotation. Use may be made of either a Cardan suspension mechanism or link mechanism for supporting the sensor member. When use is made of a link mechanism, toe and camber angles can be detected by the same encoder.
