Title: Amplifier circuit, bipolar transistor and amplification method
Inventor: HANEDA SHOJI
IPC: H01L21/331
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To obtain an amplifier circuit and an amplification method, which show little nonlinearity and delay of signal propagation and obtain a bipolar transistor with which the amplifier circuit and amplification method can be realized easily. SOLUTION: The base B of a transistor Q, connected to its emitter E, has 1st and 2nd base terminals tB1 and tB2. The collector C of the transistor Q is connected to the base B. If a voltage by which continuity between the base B and the emitter E of the transistor Q is obtained is applied to the 2nd base terminal tB2 of the transistor Q, a collector current is made to flow between the collector C and the emitter E of the transistor Q via a load ZL. The change of the collector current is substantially proportional to the change of a voltage applied between the base B and the emitter E via the 1st base terminal tB1. A voltage applied to the 1st base terminal tB1 is not necessarily high enough to obtain continuity between the base B and the emitter E.

Abstract: PURPOSE:To simplify channel setting by providing plural decoders to which intermediate frequency signal are distributed within a same case body, converting respective demodulating outputs into high frequency signals with different ground broadcast bands respectively and after that, mix-outputting them. CONSTITUTION:Plural decoders 14, to which intermediate frequency signals are supplied from a distributor 13, demodulate them and output them to a RF converter 15.

IPC: H02M3/155
Filed: 1989-05-08
Abstract: PURPOSE:To reduce loss in a voltage dropping system auxiliary power circuit by taking advantage of a chopper by a switching transistor of a main circuit to supply voltage to the auxiliary power circuit. CONSTITUTION:When a switching transistor 5 is turned ON, a collector voltage VCE reaches about 0V. When the switching transistor 5 is turned OFF, a continuity of a free wheel diode 16 is made, so that the collector voltage VCE reaches about voltage VB of a battery 1. A diode 16 also repeats ON and OFF operation according to such repeated operation that the collector voltage VCE of the switching transistor 5 reaches 0V and the battery VB, and power is supplied to the auxiliary power circuit 11 intermittently. The loss in a voltage dropping system power circuit is proportionate to the difference between input voltage and output voltage, so that when an average input voltage VCE drops, the loss in the auxiliary power circuit 11 is reduced, and the efficiency of a DC-DC converter is promoted.

Filed: 1981-07-22
Abstract: PURPOSE:To obtain the titled material capable of arbitrarily controlling and keeping the pressure of H2 in a vacuum apparatus by means of the surrounding temp. and the residual H2 content by specifying the atomic ratio of a Zr-V alloy. CONSTITUTION:This material is an alloy represented by a general formula ZrVx (where x is 0.01-0.28). The alloy is somewhat viscous, it does not ignite in air even after repeating H2 absorption and release, and it shows well the expected performance in the form of lumps without requiring pulverization prior to use. A Zr-V alloy is homogeneously solubilized by heating to >=1,860 deg.C, and the alloy having the desired composition is easily obtd. by an Ar arc melting method or other method. The Zr-V alloy of this purpose is required to have >=90mol% beta- Zr phase, so the value of x is restricted to said range. When the value of x exceeds the upper limit, H2 is absorbed at a lower temp. under a much lower pressure of H2, yet H2 is released under a relatively high pressure. When the value of x is blow the lower limit, H2 is not almost absorbed at <=400 deg.C and pretreatment at a higher temp. such as heat treatment or activation is required.
