IPC: G11B19/28
Filed: 1977-10-31
Abstract: PURPOSE: To increase the sensitivity of detection of the deviations in the number of revolutions by phase comparing both outputs of a frequency generator and a reference signal oscillator.  
     CONSTITUTION: When the revolutions of a rotator 1 are transmitted to a frequency generator 2 by way of a shaft 8, this FG 2 generates the outputs having the frequencies proportional to the number of revolutions of the rotator 1. A phase comparator 4 compares the phases of the output signal of the FG 2 and the output signal of OSC 3 and generates an output. A two color light emitting diode 7 emits red and green light. Here, the state where the number of revolutions of the rotator 1 is the same and phases have advanced. As a result the phase of the FG 2 also advances and therefore if θ is assumed to have changed from 0 to π/2, then it turns out that the light changes to a reddish orange color.

Title: Semiconductor device
Inventor: SUZUKI TETSUO
IPC: H01L27/088
Filed: 1978-10-26
Abstract: PURPOSE:To obtain a device in which high resistor and a transistor are connected in parallel by forming a part of MISFET channel as a depletion type and the other  part as an enhancement type. CONSTITUTION:Ions are implanted in a channel area with use of a resistmask and a part of an enhancement type is changed into an active dpletion type. This leads to a device in which an enhancement type FET is connected with the high resistance in parallel, as a whole. When this device is used in both the load side of an inverter circuit and a transistor T2, the leakage from an operating transistor T1 is compensated by a current in the depletion channel area of the transistor T2 so that output at OUT is able to be maintained at ''H'' level for a long period. Thus in the case of constituting a memory circuit, a refresh interval can be made wider.

Title: Dielectric porcelain composition
Inventor: SHIROTA KOJI
IPC: H01B3/12
Filed: 1993-06-02
Abstract: PURPOSE:To provide a dielectric porcelain composition which especially can be sintered at low temperatures and is of a high dielectric constant and a low loss and suitable for a dielectric material for a multilayer capacitor and the like of a small size and a large capacity. CONSTITUTION:A dielectric porcelain composition is a three component composition of Pb(Mg1/3Nb2/3)O3, Pb(Fe1/2Nb1/2)O3, and Pb(Zn1/2W1/2)O3. When it is expressed by a formula of Pb[(Mg1/3Nb2/3)x(Fe1/2Nb1/2)y(Zn1/2W1/2)z]O3, x, y, z exist within a region surrounded by points A-E. Accordingly, it is having a high dielectric constant, a low dielectric loss, high insulation resistance, and small temperature change of the dielectric loss, and it is possible to provide a small-sized capacitor of high reliability and high capacity. Since a sintering temperature is low, a baking cost is low. Consequently, in the case where this composition is used for a multilayer capacitor, relatively inexpensive metal such as silver can be used without using expensive noble metal such as palladium or platinum as an inside electrode.

Abstract: PURPOSE:To remarkably enhance the heat resistance of a twisted wire without excessively reducing the strength and heat conductivity by suitably drawing a plurality of rough wires of an Al-Zr alloy contg. Fe and Si and by twisting the drawn wires together in the form of a multiple layer.
