Patent JP-S61194906-A (JP)
Title: Operational amplifier circuit
Inventor: YOTSUYANAGI MICHIO
IPC: H03F3/45
Filed: 1985-02-22
Abstract: PURPOSE:To form an operational amplifier circuit in which a common mode input voltage range is taken at least from a positive power voltage to a negative voltage and whose operating point is stable by using the differential input stage by the 1st and 2nd MISFET differential pairs and a common load to them as components. CONSTITUTION:The 2nd differential pair via source follower is provided to the input stage. Even when an input common voltage VIN is fed to an input terminal via the source follower, the level of the input gate of the 2nd differential pair is lowered by the source follower and a prescribed common mode voltage only is fed, then even when the 1st differential pair is inactivated, the 2nd differential pair acts normally to function the operational amplifier. Further, the range of the common mode input voltage VIN is taken at least to the positive power voltage by adjustment. Since the common mode voltage range of the 1st differential pair is decided, the negative common mode voltage is taken up to the negative power voltage. Since a current flowing a transistor (TR) M5 flows all to TRs M3, M4 regardless of the operation of TRs M1 and M21, so long as the TR M5 is regarded as a constant current source, the voltage at a point (a) is very stable and the output operating point is not fluctuated.

Abstract: PURPOSE:To improve mass-productivity and a physical characteristic by combining a layer including inorganic scale material having a high density and a low elastic modulus with a layer including scale material having low density and a high elastic modulus and using the former as an intermediate layer so as to obtain a three laminated construction. CONSTITUTION:A diaphragm 1 is laminated with three layers; its surface and the bottom layer are made of an inorganic scale layer 1a including mainly graphite powder with high elasticity and low density and a little of mica powder with low elasticity and high density, and an intermediate layer is made of an inorganic scale layer 1b including mainly mica powder with low elasticity and high density and a little of graphite powder with high elasticity and low density. In this case, graphite powder as an inorganic scale with high elasticity and low density and mica powder with low elasticity and high density are uniformly scattered in paper-making water and naturally caused to deposit on a paper-making net. During this process the mica powder with high density settles down prior to the graphite, and on the mica layer the layer mainly made of the graphite powder is formed. Then the laminated body is transferred on other paper-making net, and the mica layer on the mica layer is deposited and the graphite layer on said mica layer is deposited. The mixture of epoxy resin and a stiffener is impregnated into the laminated body.

Title: Frequency conversion transmission system
Inventor: TANAKA HIROYUKI
IPC: H02J3/34
Filed: 1991-02-28
Abstract: PURPOSE:To increase power transporting ability by transmitting power, converting into a frequency (usually 10-30Hz) lower than a commercial frequency. CONSTITUTION:Frequency converters 4, 5 are put between a generator 1 and the beginning end of a transmission line 2, and between the termination of the transmission line 2 and a load 3 respectively. Hereupon the frequency of the AC power generated by the generator 1 is 60Hz. But the frequency is converted from 60Hz to 20Hz by the frequency converter 4 on the side of the generator 1, and converted reversely from 20Hz back to 60Hz by the frequency converter 5 on the side of the load 3. Incidentally, the frequency of the power is considered to be 20Hz, but it is judged that a range of 10-30Hz is appropriate. And this constitution makes it possible to transport more power on the same transmission line and to raise the transportation efficiency.

Filed: 1993-02-24
Abstract: PURPOSE:To prevent the resistance of the conductive layer, formed on a semiconductor substrate, from increasing when subjected to a large current for a long time by placing low melting point metal in contact with the conductive layer. CONSTITUTION:The title semiconductor device consists of a semiconductor substrate 1, conductive layer 5 formed thereon and low melting point metal 6 placed in contact with the conductive layer 5. For example, an n-type diffusion layer 2 is formed on a p-type silicon substrate 1, and a layer insulating film composed of silicon oxide 3 is formed to cover the circuit elements formed on the substrate 1. Contact windows 7 are in the silicon oxide film 3 on the n-type diffusion layer 2. A conductive layer of a laminated film composed of barrier metal 4 and aluminum alloy 5, is formed on the silicon oxide film 3, and low melting point metal 6 is placed on the aluminum alloy 5. Thus, even if a large current passes through the conductive layer and causes voids therein, accompanying temperature rise fuses the low melting point metal and the melted metal fills the voids. This prevents the resistance of the conductive layer from increasing.
