Title: Amplifier for microphone device
Inventor: SATOU SHINICHI
IPC: H03F1/34
Filed: 1980-10-21
Abstract: PURPOSE: To achieve broad operating range and stable gain, by controlling the operating point of an output stage transistor (TR) and gain independently through the provision of a differential amplifier at the prestage of a main amplifier and feedback loop to control the gain of main amplifier.  
     CONSTITUTION: The output signal of microphone 2 is amplified differentially, a collector current of a transistor (TR)3 is a base current of a TR1, and the TR1 takes a resistor (R)4 at the receiving end as a load. The gain to the AC component can be set to a desired value, by suitably selecting the values of R8, R9. On the other hand, as to DC, the operating point of the TR1 can be determind arbitrarily with the base potential of the TR3 through the distibution of R6, R7. Further, in a diode 9, the DC potential to the amplifier B is made higher than the potential at the collector of the TR1, the power voltage to the amplifier B is supplied through an R10, and a capacitor C8 by-passes the AC component. With this constitution, stable output over a wide range can be obtained by commonly using the power supply line of the amplifier and the output signal line.

Abstract: PURPOSE:To enable 2-color recording and overlay recording, by providing 2 photoconductive layers different in sensitivity to color lights and in ability to transfer photocarriers on a conductive substrate.

Title: Picture processing device
Inventor: TOMOSADA MASAHIRO
IPC: G03G21/14
Filed: 1984-07-16
Abstract: PURPOSE:To reduce generation of a miscopy by programming in advance an operating mode of a condition required for a standard copying operation, and resetting it to a standard mode after the lapse of a fixed time, after a copying operation has been ended. CONSTITUTION:When an IS is generated by an initial signal, an FF constituted of Q3 and Q4 is reset by the IS. Therefore, a full color mode is read by an initializing switch SWS of a copying mode, and the full color mode is outputted by a multiplexer Q6. When it is desired to change a color mode from full to other, it can be changed by selecting mode switches SW1-SW9. For instance, when the SW2 is turned on, its copying mode is stored with the 2nd code ''1'' by a register Q5. Since the FF constituted of Q3 and Q4 is set, a copying mode signal selected by the SW2 is outputted by the multiplexer Q6. In this way, copying of a standard mode which is used frequently can be executed without requiring a special trouble.

Abstract: PURPOSE:To improve reverse withstand voltage by removing a part having no relation to a light emitting function of an outer periphery in contact with the peripheral wall of an element of an electrode formed at least on one side surface of a semiconductor light emitting element. CONSTITUTION:A part not covered with a mask 7 of a semiconductor layer 5 is etched to a predetermined depth to form a ridge 1. After the etching mask 7 is further removed, the entire surface of the layer 5 is coated with heat resistant high resistance resin 2 in thickness of the degree that the upper surface becomes flat and cured. Thereafter, the resin 2 is removed from an upper part until reaching the top of the ridge 1. In order to remove resin, ashing by an oxygen plasma is normally conducted. Then, a p-type side electrode 3 is deposited on the layer 5, and an etching mask 6 of the same shape as that of an electrode to remain on the electrode 3 is further formed. An entire element is immersed in an electrode etchant for about 20 sec to remove the part of the electrode 3, not covered with the mask 6 by etching. The mask 6 is removed by solvent. Thus, a pass of a surface leakage current is not almost formed, its reverse withstand voltage can be improved, thereby improving reliability of a semiconductor light emitting element.
