IPC: G01D3/00
Filed: 1983-03-11
Abstract: PURPOSE:To measure a pressure value in an optional place in a vacuum system by displaying a pressure value obtained by multiplying a coefficient to a pressure value shown by a signal obtained from a pressure measuring, sensor attached to an optional place in a vacuum system discharged by a discharging pump, as a pressure value of a place being different from a sensor attached place in the vacuum system. CONSTITUTION:Places for measuring pressure in a vacuum system 10 are three points of A, B and C, and a sensor 12 is attached to the place A to which a sensor of a pressure measuring means can be attached easily, among them. An output of the sensor 12 is converted to a pressure signal in a measuring means 13, and used as a signal for displaying a pressure value PO of the point A on a display device 14a for constituting a pressure display means 14. Also, an output of the measuring means 13 is applied to operating circuits 15b, 15c, too, but the operating circuits 15b, 15c supply a display signal corresponding to a pressure value obtained by multiplying each prescribed coefficient K1, K2 to the pressure value PO shown by these applied signals, to indicators 14b, 14c of the pressure display means 14. As a result, pressure values P1, P2 corresponding to the point B and the point C are displayed on the display devices 14b, 14c, respectively.

Filed: 1980-03-28
Abstract: PURPOSE:To form an excellent window for contact by performing anode oxidation by using electrolytic solution containing fluoric acid and thereby removing in a short time a nitride film provided on a semiconductor wafer completely. CONSTITUTION:The wafer having an epitaxial layer 2 wherein an element region is to be formed is prepared n a semiconductor substrate 1. After the element region is formed, openings are made selectively in a silicon oxide film 5 and a phosphorus glass layer 6 and thereby contact parts are formed. Consecutively, a silicon nitride film 7 to be a surface protecting film is made to grow on the whole surface of the wafer. Next, current is made to flow in the electrolytic solution containing fluoric acid and only the nitride film in the part of the window for contact is removed through melting by the method of anode oxidation. Since the fluoric acid is contained in the electrolytic solution, the nitride film subjected to the anode oxidation  is melted quickly, and as the result, the nitride film can be removed completely in a  short time. The appropriate density of the fluoric acid is 1:100-1:50 of fluoric acid  to electrolytic solution in the content ratio.

Title: Diode and electric power conversion device
Inventor: NAGASU MASAHIRO
IPC: H01L29/861
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To improve the critical di/dt of a diode and to improve with it the conversion efficiency of a power conversion device by increasing a region where a second main electrode does not contact a second semiconductor layer at the edge part of the second semiconductor layer. SOLUTION: An L part is arranged at the boundary part of a termination region and an active region. An L is the distance (retreating distance of an anode electrode 16) between the last edge part on the termination region side of the p<+> conductor type semiconductor layer 11 and the farthest peripheral part of the part where the anode electrode 16 contacts the p<+> conductor type semiconductor layer 11. The value of the critical di/dt of the diode largely depends on the retreating length L of the anode electrode 16 and one of factors is the diffusion length of positive holes in an n<-> conductor type semiconductor layer 14.  If the retreating length of the anode electrode 16 is set longer than the diffusion length of the positive holes of the n<-> type semiconductor region 14, the local concentration of the current inside the n<-> conductor type semiconductor layer 14 at the recovery is prevented, the diode is harder to break and the critical di/dt is improved.

Then the both-terminal voltage of the resistance R5 connected between the terminal a3 and the ground is applied to the comparison input terminal of the CP. The CPU produces the preference deciding output when the voltage of the comparison input terminal exceeds the reference voltage level.

Title: Chromium plated rolling roll
Inventor: IZUSHI TOMOYA
IPC: C23C30/00
Filed: 1985-03-04
Abstract: PURPOSE:To lower the initial wearing speed of roll and to perform easily schedule-free rolling by properly lowering the surface roughness of a rolling roll lower than the initial one before or after plating the surface of the roll with chromium. CONSTITUTION:In a chromium plated rolling roll, the surface roughness of a rolling roll is lowered from the initial one by 5-20% by Rz before or after plating the roll with Cr. In this way, a peak part of the surface roughness of Cr-plated roll is smoothed, and the initial wearing speed of the roll in service is lowered, and the generation of the difference in surface roughness between the passing part and non-passing part in rolling is reduced. Thus, the schedule- free rolling is easily performed, and the operating efficiency of mill is improved.

Title: Preamplifier for optical communication
Inventor: NAKAMURA KAZUHIKO
IPC: H03F3/08
Filed: 1985-03-04
Abstract: PURPOSE:To obtain a preamplifier with a wide dynamic range, high band width and large gain by giving an output of a converting amplifier amplifying an output of a photodetector to one input of a differential circuit and giving an output of a reference voltage generating circuit of the same constitution as the converting amplifier to the other input. CONSTITUTION:The output of the photodetector is amplified by the converting amplifier 1 and the output of the amplifier and the output of the reference voltage generating circuit 2 activate the differential circuit 3. Thus, the gain is increased as a whole and the output amplitude is limited to a constant value. Since the amplifier 1 and the generating circuit 2 are of the same constitution, each output is changed identically in response to the fluctuation of power voltage and temperature and operated very stably as a whole. Thus, it is possible to give a proper gain, band, dynamic range and noise characteristic to the amplifier 1.

Abstract: PURPOSE:To eliminate position discrepancy caused by delivery of a wafer by a method wherein a wafer put and fixed on an X-Y table which is enabled in reciprocal movement precisely and moved from the prealignment position to the precision alignment position with the X-Y table. CONSTITUTION:An upper stage 7b of an X-Y table 7 is enabled fine movement against a lower stage 7a precisely to the axial directions of X-X' and Y-Y'. A guide means and a driving means are provided to give the lower stage 7a reciprocal movement by a certain distance horizontally as shown by a double- directional arrow B-B'. Three-point rollers 2a-2c and a positioning roller 3 are provided on the X-Y table 7 for prealignment of the wafer 1. With this constitution, as it is not necessary for the wafer 1 to be attracted and held, surface contamination of the wafer 1 is avoided and, as such processes as attracting and holding   transport   delivery are not included, position discrepancy caused by transport and delivery is eliminated.

Title: Self diagnosis system for pulse train counting rate meter
Inventor: KANO ICHIRO
IPC: G01T1/18
Filed: 1985-03-04
Abstract: PURPOSE:To make a prompt detection possible by switching a switch at the time of self-diagnosis and counting the pulses produced by pulse generating means. CONSTITUTION:Pulse train signals generated at a detector 1 and simulating pulse train signals from a pulse train generating circuit simulating them are switched by a changeover switch 2 and calculated by counters 8 and 9. The simulated pulses are adapted to have a predetermined counting rate by eliminating clock signals as from the count value of the pulse number designated by a CPU 7 to a DOS 4 by taking an AND 13 of the output clock signal of the oscillator 3 and the output of the digital one-shot (DOS) 4. To the DOS 4 are supplied count values desired to be counted by the counters 8, 9. At the outset of the counting period, a timer 6 inputs start signals, the DOS 4 starts counting the input pulse train and supplies the pulse train as the output of the AND gate 13 until the count value reaches a preset value. As from the preset value, the DOS controls the output of the AND gate 13, while the output of the pulse train becomes zero until the next start signal input.
