IPC: H03K3/356
Filed: 1979-10-09
Abstract: PURPOSE:To enable high switching operation, by connecting the drain of two isolation gate transistors, in which the gate and the drain are mutually in cross-connection, to the emitter of two bipolar transistors.

Abstract: PURPOSE:To prevent the deterioration of sensitivity for dust detection, by a method wherein the drop of the quantity of light from a light-emitting element is detected and its compensation is done by its detected output so that the sensitivity of a dust-sensing part is kept constant. CONSTITUTION:At a DC power source, a resistance 21 and a light-emitting element 22 are connected in series, and the light-emitting element 22 is turned on.
