Title: Amplifier
Inventor: MIZOE JUN
IPC: H03F3/193
Filed: 1993-03-24
Abstract: PURPOSE:To ensure the matching of gains in a wide-band and also to suppress the temperature variance by using a posistor having its resistance value increasing with rise of the temperature as a negative feedback impedance element of an amplifier element. CONSTITUTION:The signal received from an input terminal 1 is applied and amplified via a gate input matching inductor 3 of an amplifying transistor TR 6. The amplified output is led out through the drain of the TR 6 and then transmitted from an output terminal 7 via an output matching inductor 4. A negative feedback circuit consists of a series circuit of a matching inductor 5 and a posistor 2. The posistor 2 serves as an element which increases its resistance value Rf (T) with rise of the temperature T. Thus the gain fluctuation of the TR 6 is compensated by the temperature characteristic of the posistor 2. Furthermore dRf (T)/dt of the posistor 2 is set at such a level that can offset the gain variance due to the temperature change of the TR 6 and the gain various due to the change of negative feedback value with each other. So that the temperature variance of gains can be reduced and also the matching of gains is ensured in a wide band.

Abstract: PURPOSE:To obtain CdS having more favorable properties as fine particles and more favorable photoconductive characteristics, by heating a mixture of CdS with a flux to a specified temp. below the m.p. of the flux before calcination. CONSTITUTION:When a mixture of CdS with >=20wt% flux basing on the amount of the CdS is put in a calcining vessel such as a quartz crucible and calcined, the mixture is held at a certain uniform temp. above 100 deg.C for a while before the flux is melted. All of water contained in the CdS and flux is evaporated, and the internal temp. of the crucible is made uniform. The mixture is then calcined by uniform heating to a temp. >=50 deg.C above the m.p. of the flux. Since uniform calcination is carried out at any place in the crucible, reproducibility in the shape and electric characteristics of particles can be enhanced.
