Filed: 1985-10-17
Abstract: PURPOSE:To eliminate the fluctuation of an output low level voltage due to the function of a power voltage and a resistance value by setting a low level voltage of a buffer amplifier based on a common voltage. CONSTITUTION:Transistors (TR) 16, 17 are turned on/off respectively by an input to input terminals 14, 15 to boost an emitter voltage of a TR 21. Then a base voltage of a TR 12 rises and a base voltage of a common emitter TR 6 is lowered to output a low level at an output terminal 3. In this case, a current flows to a diode 11 whose anode reaches a voltage higher than that of a base of the TR 6 by a voltage VBE with respect to common, the base voltage of the TR 6 is decreased, the saturation of the TR 6 due to too lowered collector voltage is prevented, the collector voltage and the base voltage of TRs reach a voltage higher than the common potential by the voltage VBE. As a result, a low level output decided by a common voltage, independently of the effect of the power voltage fluctuation or the fluctuation of resistors 18, 19 is generated.

Filed: 1990-09-03
Abstract: PURPOSE:To obtain a desired output voltage safely and reliably by detecting an input voltage upon selection of an output voltage and then stepping up or down the detected input voltage, as required, thereby modifying the output voltage into a selected one. CONSTITUTION:Upon selection of 100V input/100V output, selection switches S1, S2 in an output voltage selecting circuit are connected to 100V side and only a relay (c) is excited in an input voltage detecting circuit 30 whereas relays Ry1, Ry6, Ry7 are excited in a relay control circuit 40.

Abstract: PURPOSE:To easily recognize the importance of a trouble by providing plural pieces of integrated alarm display lamps, and changing the number of pieces of integrated alarm display lamps which are turned on at the time of generation of an alarm in accordance with the importance of the alarm. CONSTITUTION:When a data processing part 1 and a data processing part 3 become a fault, alarm signals 100, 102 are inputted to a two-input deciding part 4 and an OR logic part 5, respectively. Since the alarm signal 100 and the alarm signal 102 are inputted, the two-input deciding part 4 outputs a lamp lighting signal 103 to a lamp driving part 6, and the lamp driving part 6 which receives the lamp lighting signal 103 turns on a lamp 8. Also, when the alarm signals 100, 102 are inputted, the OR logic part 5 outputs a lamp lighting signal 104 to a lamp driving part 7, and moreover, the lamp driving part 7 which receives the lamp lighting signal 104 turns on a lamp 9 by a lamp driving signal 106. In such a way, a responsible person of an alarm system can recognize easily the importance of the trouble by only looking at the integrated alarm display lamps 8, 9 which are turned on.

At the time of the kick-down operation, an operating member 48 is pushed in by a shifting cam 51 so that a transmission control valve 44 is downshifted. When the kick-down operation is performed above the set vehicle speed V0, switches 62, 63 are both turned off so that the actuator 61 is put into action. At that time, the operating member 48 is pushed in by the actuator 61 independently of the shifting cam 51 so that the transmission control valve 44 is downshifted.
