Title: Facsimile receiver and copying machine
Inventor: KONISHI MASAO
IPC: H04N1/29
Filed: 1979-04-18
Abstract: PURPOSE:To make it possible to easily perform both copying of a original and receiving of facsimile by use of one device, by devising so that positive and negative copies can be obtained by a simple handling. CONSTITUTION:A sensitive drum of the copying machine consists of a conducting substrate 26a, a photoconductive layer 26b made of semiconductor such as selenium, etc., and an insulating layer 26c made of ''Mylar '', etc. In case a negative copy is made, the primary charger performs a uniform electric charge, and charges the surface and the reverse side of the layer 26c to (+) and (-), respectively. Subsequently, a light image (a) is projected, the surface of the projected part 7 is charged electrically, and after that, the whole surface is exposed. Resulting from the foregoing, the photoconductive layer becomes conducting, the remaining load electric charge ceases to exist, the electric charge of the right part remains, and a negative copy can be obtained. In case of a positive copy, the light image is projected after the secondary electric charge has been finished. Thus, the remaining electric charge in the photoconductive layer of the light irradiated part ceases to exist, and the surface potential difference is caused in accordance with the change- over pattern, by which a positive copy can be obtained.

Abstract: PURPOSE:To obtain a high performance laser without almost exerting thermal influence to an oscillation layer in the diffusion of a short time by superposing a GaAlAs layer on a cap layer and diffusing an impurity from the surface. CONSTITUTION:An N type Ga1-xAlxAs(0<x<1) 3, a Ga1-yAlyAs(1>=y<1, x>y) active layer 4, a P type Ga1-xAlxAs 5 and an N type GaAs cap layer 6 are laminated on an N type GaAs substrate 1.

IPC: G08B21/08
Filed: 1985-03-13
Abstract: PURPOSE:To conserve power supplied to a hot wire type semiconductive element and to prevent the deterioration of a catalyst, by performing the intermittent supply of a current, which connects power in a sec unit at a min unit cycle, to the hot wire type semiconductive element and detecting the output at a transient time prior to the thermal stabilization of the hot wire type semiconductive element. CONSTITUTION:A coil shaped platinum wire 1 is closely adhered to a metal oxide conductor 2 compring SnO2 or ZnO to constitute a hot wire type semiconductive element 3. A bridge circuit 10 is constituted of this element 3, a compensation element 3A and a resistor Rb. The intermittent supply 11 of a current for lasting power for 1-2sec at a 2-3min cycle from a battery E is performed and voltage is detected by a variable resistor R. When CO2 or H2 is present in atmospheric gas, the conductivity of the element 2 rises and a resistance value is reduced and the output at a transient time prior to thermal stabilization is detected by the resistor R to send a signal to an alarm. Because the transient phenomenon, immediately after a power source was closed, is utilized, gas is detected with good sensitivity and power can be conserved.
