摘要： A downshift control device for an automatic transmission is provided in which a drive command is generated to a shift actuator when a shift command to change a gear ratio of the transmission is generated, to switch a shift valve and change oil paths, thereby to release a first engaging element that has been engaged in a first gear position established by the automatic transmission before the shifting operation, and engage a second engaging element that has been released in the first gear position, so as to establish a second gear position after the shifting operation. This downshift control device includes a pedal-depressed downshifting determining means for determining whether the automatic transmission is to be shifted down due to depression of an accelerator pedal, a delay time setting means for setting a delay time that ensures an increase of an engine speed due to depression of the accelerator pedal, and a shift valve operating timing control means for generating the drive command for switching the shift valve to the shift actuator when the delay time elapses after the pedal depressed downshifting determining means determines that the transmission is to be shifted down due to depression of the accelerator pedal.

摘要： An output circuit for outputting a control signal through a transistor to a controlled apparatus including an output detecting section for detecting the control signal and an external power supply for supplying a power to the output detecting section, a voltage due to the external power supply being applied to between a collector and emitter. The output circuit comprises a capacitor coupled in parallel to an output detecting circuit comprising the output detecting section and the transistor coupled in series to each other and resistor means coupled in series to a parallel circuit comprising the output detecting circuit and the capacitor so as to give a series resistance with respect to the parallel circuit. The output circuit further comprises a switch disposed to be parallel to the resistor for bypassing the resistor to substantially reduce the series resistance up to zero when a voltage between terminals of the capacitor is above a predetermined value. This arrangement can prevent the transistor from instantaneously taking the ON state, thereafter ensuring the normal operation by bypassing the resistor means through the switch.
