摘要： The semiconductor circuit includes a voltage-controlled semiconductor device (N)N, the resistance value of which is controllable with a high voltage, the drain terminal of the N can be connected to the gate terminal (control terminal) of an output semiconductor device (NO) via a resistor (R) or to a last output stage of the driver circuit, the source terminal of the N is connected to the emitter terminal of the NO, and the gate terminal of the N is connected to the collector terminal, which is the output terminal, of the NO. When the input terminal of the semiconductor circuit is at the Hi-level, the NO OFF. By connecting the output terminal of the NO to the high-potential-side of a high-voltage circuit disposed separately and the negative electrode of a control power supply (VDD) to the low-potential-side of the high-voltage circuit in the state, in which the NO is OFF, a desired high voltage is applied between the collector and emitter of the NO. Since a p-channel MOSFET (PD) is turned ON as the input terminal potential is changed over to the Lo-level and the high voltage is still being applied to the output terminal of the NO, the N is turned ON and the NO is brought into the ON-state, in which the current driving ability of the NO is low. The semiconductor circuit can protect the devices from an over voltage with a simple circuit configuration.

摘要： In the disclosed camera, a switchover arrangement automatically shifts from an automatic exposure mode to a flash mode in response to a charge completion signal from a flash device. A line electrically connects a terminal capable of receiving the charge completion signal from the flash unit to the switchover arrangement. A switch connected to the connecting line applies a signal of a value corresponding to the charge completion signal from a signal source in the camera to the switchover arrangement to cause the latter to effect a switchover to the flash mode in response thereto in the same manner as when a charge completion signal is applied thereto.
