Title: Electrophotographic receptor
Inventor: KAWAKAMI HARUO
IPC: G03G5/08
Filed: 1979-10-16
Abstract: PURPOSE: To obtain a photoreceptor of good spectral sensitivity, and superior heat resistance and printing resistance by providing a charge transfer layer by As 2 Se 3  on a conductive substrate and a charge generating layer of the composition of xAs 2 Se 3 -yAs 2 Te 3  of x, y in a specific range threeon.  
     CONSTITUTION: An As 2 Se 3  layer 3 of 178°C glass transition point is vacuum-evaaporated on a conductive substrate 1, for example, a substrate formed with an interface layer 2 of Al 2 O 3  by subjecting the surface to nitric acid treatment, whereby a charge transfer layer 3 is formed. Next, a charge generating layer 4 of the composition xAs 2 Se 3 -yAs 2 Te 3  (x:y is between 11W1/8) is evaporation deposited on the layer 3. The alloy of this composition range is of about 130W170°C in glass transition point and if the content of As 2 Te 3  is high, it has a large coefficient of absorption for long wavelengths, but since the specific resistance is lower to about 1/10 6  than that of As 2 Se 3 , the above-mentioned range composition is imployed. In addition, the above-described composition alloy is higher in hardness than As 2 Se 3 . In this way, the photoreceptor of superior heat resistance and print resistance power and good spectral sensitivity is obtained.

Title: Solar heat collector device
Inventor: MATSUMOTO KAZUO
IPC: F24S90/00
Filed: 1983-07-20
Abstract: PURPOSE:To enable a heat collection pump to be operated with a solar cell having low capacity by a method wherein under an actuation value setting mode, a minimum output value of solar cell which enables a continuous operation of a heat collection pump is calculated and under a normal operation mode a heat collection pump is enabled to operate under assistance of a secondary cell. CONSTITUTION:When the outputs from temperature sensors T1 and T2 are fed and a difference more than the desired value is detected, a first switch S1 is turned on, a power is supplied from a solar cell 3 and a pump P is started to operate. During the time in which the difference between the outputs from the temperature sensor T1 and T2 is more than the desired value, the operation of the pump P is continued. It is decided whether the secondary cell 4 is charged with the solar cell 3 or not in response to the output values of the ammeter A and the volt-meters V1 and V2. If it is judged that the charging can be performed, the third switch S3 is turned on and in turn if the charging can not be performed, the third switch S3 is turned off. If the output value I is more than the energization value I3, the second switch S2 is turned on to connect the secondary cell 4 and the pump P is energized under an assistance of the secondary cell.

IPC: H02H7/20
Filed: 1986-06-11
Abstract: PURPOSE:To reduce a clamping voltage by composing an input protective diode of a junction diode formed between an N+ type buried layer and a P<+> type buried layer. CONSTITUTION:A region for surrounding an isolation island region, i.e., a P-type semiconductor substrate 101, an isolation diffused layer 107 and a P<+> type buried layer 109 are operated as the anode of an input protective diode. The reverse breakdown voltage VR of the diode for deciding the clamping voltage of the input protective circuit is determined by the layers 109, and an N<+> type buried layer 105 for forming a high density P-N junction. Accordingly, it can be sufficiently reduced as compared with the case that it is decided by the isolation diffused layer and the N<+> type buried layer. Thus, the clamping voltage of the input protective circuit can be reduced without decreasing the circuit impedance.

Title: Semiconductor laser element and photoelectronic device into which said laser element is incorporated
Inventor: SAKAKI SHIGEO
IPC: H01S5/00
Filed: 1985-06-21
Abstract: PURPOSE:To obtain a semiconductor laser element having high reliability by forming a groove, which is shaped in parallel with the main surface of a substrate on both sides of a resonator and divides a P-N junction, and a passivation film coating the surface of the groove. CONSTITUTION:The surface on the side where a resonator 11 is mounted, the main surface, is flattened. Consequently, when a laser chip 1 is fixed to a mounting plate such as a sub-mount 14 through a cementing body 15 such as solder, the main surface as a fixing surface is flattened, thus preventing the inclined fitting of the laser chip 1, then keeping the position of the resonator 11 constant. A double hetero-junction is divided by grooves 12. Since the grooves 12 are formed through etching, the crystallizability of the surfaces of the grooves are made extremely better than that by rupture the due to scribing, etc. The surface is coated with a passivation film 13. Accordingly, the leakage of currents in the double hetero-junction exposed to the surfaces of the grooves 12 is inhibited, thus preventing the generation of the deterioration of characteristics, then improving reliability.
