[OBJECT] To provide a radiation detector that allows a substrate with a semiconductor layer, and a light emitting device, to be attached simply. [SOLUTION] A glass substrate 11 having an X-ray sensitive semiconductor 14 for converting incident X rays into carriers, and a planar light emitting mechanism 28 disposed on a side opposite from an X-ray incidence side of the glass substrate 11, are provided to remove carriers remaining in the X-ray sensitive semiconductor 14 by means of light emitted from the light emitting mechanism 28. Since a gel-like adhesive sheet 32 having light transmissivity is interposed between the glass substrate 11 and light emitting mechanism 28, and the light emitting mechanism 28 is planar, the glass substrate 11 and light emitting mechanism 28 can be attached simply. Since the adhesive sheet 32 interposed has light transmissivity, the light emitted from the light emitting mechanism 28 can be transmitted through the adhesive sheet 32, without being blocked, to irradiate the glass substrate 11.

In a light sensitive semiconductor unit having a plurality of light sensitive semiconductor cells connected in series, the light receiving area or size of the light sensitive semiconductor cells is increased as the distance from the center of the unit increases so that every light sensitive semiconductor cell can generate generally equal short circuit current even if the light intensity is decreased as the distance between the light sensitive semiconductor cell and light source increases, whereby a high operating voltage can be obtained.

Solid state optically activated switches in which a plurality of spaced cacts are arranged in a line on one of the broad surfaces of a semiconductor wafer and one or more bridging electrodes are arranged on the opposite broad surface thereof. The two end contacts are the switch terminals. This arrangement directs the electric field and the load current into the bulk of the semiconductor in a zig-zag fashion to provide a high hold-off voltage and a short conduction path. Also the bridging electrode can be used as a control electrode. A novel circuit utilizing such switches is shown.

摘要:
A photo-coupler apparatus has a light emitting element in the primary side. The secondary side of this apparatus is comprised of a photoelectromotive diode array, a light sensitive impedance element series-connected to said array, a drive transistor, and at least one output MOSFET connected to the output terminals of this apparatus. The light sensitive impedance element comes into a large impedance state when an optical signal from the light emitting element is weak. In this case, the light sensitive impedance element generates a sufficient voltage to activate the drive transistor, in spite of the photocurrent being small. This results in an improvement of the dynamic sensitivity of this apparatus. When said optical signal is strong, the impedance element comes into a small impedance state, thus providing the MOSFET with a sufficient photo-current. This results in the shortening of switching times of the output MOSFET.
