Abstract: A stepping motor control circuit includes a rotation detecting means for detecting an induced signal generated by rotation of a rotor of a stepping motor, and detecting a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means for controlling driving of the stepping motor by using any one of a plurality of main driving pulses having energy different from each other or a correction driving pulse having energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means.

Abstract: A process for manufacturing a vehicle body for automobiles in which at a welding step, a vehicle body and plate-like parts to be mounted onto the vehicle body, such as a bonnet, a trunk lid, fenders and doors, are separately fabricated, and at a painting step, they are separately passed through the same painting step, or separately passed through stages excluding a topcoating and a final drying, following which they are separately subjected to the same topcoating and final drying treatments. At an assembling step, the plate-like parts which have been subjected to fitting-out are assembled onto the vehicle body after completion of fitting-out or replenishment of grease and oils for the vehicle body.
