摘要： A driving circuit for use in controlling a motor for controlling an air mixing door, an inner and surrounding air change-over door and a mode setting door and the like used in a vehicle air conditioning device, or a motor used in opening or closing of window panes of a vehicle or in opening or closing the door which includes a control transistor for use in controlling a transistor circuit having a transistor to cause both normal and reverse directed currents to flow in a vehicle motor, the control transistor being operated until a specified period of time has elapsed after the power supply switch is turned on, the motor input being shut off by the control transistor so as to prevent erroneous operation of the motor just after the power supply switch is turned on or to prevent the production of a chattering sound caused by the operation of gear trains with the motor. The control transistor is operated with a charging voltage in a capacitor for sensing a load of the motor, the motor input is shut off when an excessive load is applied to the motor, the shut-off condition of the motor input is maintained by a self-holding transistor, an electric load in the capacitor is discharged through the control transistor when the motor is stopped, the shut-off condition of the motor input is not continued with the remaining electric load of the capacitor, whereby the stationary motor may subsequently be driven.

摘要： In an auxiliary apparatus for starting a diesel engine having a quick preheating circuit operable by the switching of a key-switch from its OFF to ON position and an afterglow circuit operated by the return of the key-switch from the ST position to ON position, there is provided a heat maintenance preheating circuit to maintain the temperature of the glow plugs for a predetermined time after the quick preheating operation is finished. The heat maintenance preheating circuit for maintaining the temperature begins its operation just after the immediate heating operation by the quick preheating circuit is finished, and continues its operation for a predetermined period while the key-switch is at its ON position. As a result, even when the engine is not started to operate immediately after the initial preheating, the temperature of the glow plugs is kept at the predetermined temperature, thus assuring smooth starting of the engine.
