Title: Current sensor
Inventor: NAGAHAMA KATSUMASA
IPC: G01R19/00
Filed: 1989-03-09
Abstract: PURPOSE:To improve accuracy for current measurement by a method wherein a phase compensating circuit for compensating phase delay of the output of an operational amplifier with respect to the input is arranged between the input side and the output side of the operational amplifier. CONSTITUTION:A circuit wherein a resistor Rf and a capacitor Cf are connected in series is connected between one of input terminals (-) and an output terminal of an operational amplifier A1. This serial circuit is connected between one of input terminals (-) and the output terminal of the operational amplifier A1 in order to improve phase characteristics of the operational amplifier A1. When small signal frequency characteristics G(jomega) of the operational amplifier A1 containing resistors Rf,R1,R2 and the capacitor Cf is expressed in an equation, if a specific relation is obtained in the vicinity of frequency f0 having a recess in characteristics of secondary current i2 of a current sensor, phase delay between input voltage e1 and output voltage in the vicinity of the frequency f0 is made to a specific or smaller angle. Therefore by selecting values of the resistors R1,Rf and the capacitor Cf, recess of characteristic gain of the current i2 can be reduced.

Title: Charging machine for carbonization of formed coke
Inventor: TSUZUKI TOMIO
IPC: C10B31/02
Filed: 1978-05-12
Abstract: PURPOSE: The title charging machine designed to prevent a caking coal from powdering caused by drop impact in feeding the coal to a coke oven and to level almost charged coal, equipped with a saddle member in a specific place of the furnace.  
     CONSTITUTION: A caking coal fed from the charging chutes 3 to a coke oven is obstructed by the saddle members 4 set just under the charging chutes 3 to fall along the right and left sides of the members 4 slowly. The saddle member 4 supports the weight of a cob coal in the collecting hoppers 2 and the charging chutes 3. Since the coal in the chutes 3 falls gradually, softened crack under load of cob coal at the bottom of the charging chutes 3 can be avoided. Carbonization gases rising from the bottom of the furnace flow along the bottom of the saddle members 4 which are shaped into an inverted cone, and the cob coal below its level is heated equally by a uniform gas flow.

Title: Semiconductor device
Inventor: YAMAUCHI MASAMITSU
IPC: H01L29/812
Filed: 1981-04-14
Abstract: PURPOSE:To protect the surface of a GaAs substrate from impurity contamination by covering the surface of an aluminum gate electrode with non-porous alumina, preventing a damage, and covering the surface of the substrate between the drain and the source electrodes with porous alumina. CONSTITUTION:Aluminum 13 is deposited on an N type epitaxial layer 12 on an N type GaAs substrate 1, an anodic oxidation is performed, and the surface is converted to non-porous alumina 17. A resist mask 18 is performed on the alumina 17, is then subjected to an anodic oxidation in 2%-aqueous sulfuric acid solution, and is converted to porous alumina 19. Since an etching method is not used in this manner, a gate length can be accurately obtained as a mask pattern method, and the surface is protected from a damage due to hard non-porous alumina. Then, drain and source electrodes 15, 16 are attached to the alumina region 19. The alumina 19 is exposed with steam, and is sealed. Thus, the surface of the substrate is not exposed after the deposition, and is not accordingly contaminated. Since the surface is covered with the alumina having strong gettering effect, an inversion layer is not produced between the gate and the drain, source, and no leakage occurs.

Abstract: PURPOSE:To make it possible to adopt only merit of the conventional voltage synthesizer system and the PLL frequency synthesizer system, by interposing the second mixer between the first mixer for intermediate frequency conversion and a PLL and supplying the output of a frequency variable oscillator, which has the oscillation frequency controlled by the AFC voltage from the IF stage, to this mixer. CONSTITUTION:The second mixer 10 and frequency variable oscillator (VFO) 11 are provided further. Mixer 10 is interposed between the first mixer 3 and the PLL, and mixes output fPLL of voltage control oscillator (VCO) 5 and output fAFC of VFO11. Oscillation frequency fAFC of VFO11 is controlled by AFC output (voltage) VAFC of IF stage 4, and the fundamental frequency is controlled by the AFC voltage. As a result, degradation of tone quality and so on is not generated and the indicated frequency based on fPLL agrees with receiving frequency fANT in case of tuning slippage. Meanwhile, when the tuning frequency of IF stage 4 is shifted, AFC output VAFC appears, and VFO11 changes the frequency so that VAFC=0 may be true.

Abstract: PURPOSE:To enable reduction of variance of concentration even under different environmental conditions by using a specified iron oxide for a fine magnetic powder. CONSTITUTION:The magnetic iron oxide to be used for the magnetic toner contains a silicon element in an amount of 0.1-1.5wt.% on the basis of the iron element. The content of silicon A in the magnetic iron oxide is <=about 0.7wt.%, when the iron element is dissolved in the magnetic iron oxide in an amount of <=about 10wt.%, and that B in the magnetic iron oxide is in the range of 0.2-5wt.%, when the iron element is dissolved in the magnetic iron oxide in an amount of 90-100wt.%, and a ratio of B/A is >=1, and if the ratio is below 1, the amount of silicate compound present in the nuclei of the magnetic iron oxide in the early stage of producing it is insufficiently, and it is difficult to produce the magnetic iron oxide uniform in particle diameters and sharp in particle diameter distribution. The apparent bulk density of the magnetic iron oxide is adjusted to 0.35-0.50g/cc by using a fret mill and the like, thus permitting the variance of concentration even under different environmental conditions to be reduced.
