Patent JP-S6132537-A (JP)
Title: Semiconductor analyzer
Inventor: SHIRAGASAWA TSUYOSHI
IPC: H01L21/66
Filed: 1984-07-25
Abstract: PURPOSE:To make it feasible to analyze highly miniaturized and concentrated LSI in the atmosphere by a method wherein the surface of LSI is irradiated with laser beams to detect any current fluctuation due to electrons and holes of an electron hole couple produced within a semiconductor. CONSTITUTION:A CMOS-LSI is implanted with GND potential and power supply voltage to be irradiated with laser beams. When a point (a) on the surface of LSI is irradiated with finely throttled laser beams, an electron(-)-hole(+) couple 7 is produced in an n-well 1 corresponding to the irradiated laser power. A part of electrons and holes herein produced are extinguished by recoupling process but most of the residual electrons flow in an n<+> layer 6 reaching an outer terminal to be electron current Ie. On the other hand, most of the residual holes flow in a p<+> layer 4 reaching another outer terminal to be hole current Ih. The amount of electron current Ie and hole current Ih produced corresponding to the laser beam irradiation may mainly depend upon the position of laser beam irradiation as well as the voltages in the n<+> layer 6 and the p<+> layer 7. Therefore, each position of laser beam irradiation, kind of diffusion and status of potential may be detected in terms of Ie and Ih.

Title: Quantitatively analyzing method of acid or total iron ion
Inventor: TAKAHASHI AKIRA
IPC: G01N31/16
Filed: 1982-09-07
Abstract: PURPOSE:To measure exactly acid and total iron ion by selecting the time for adding a reducing agent, i.e., sodium thiosulfate in the range where the reducing power thereof can be thoroughly maintained and the reaction with acid is prohibited. CONSTITUTION:Alkali titration is performed from the beginning of measurement and the amt. of the alkali consumed in the titration is beforehand measured. The titration is once suspended when the pH value in the alkali titration attains the value around 1.4. A prescribed concn. or prescribed amt. of sodium thiosulfate is added to a sample and the sample is left standing until all of ferric ion is reduced to ferrous ion. The reaction FeFl3+3NaOH Fe(OH)3+3NaCl does not take place in the stage of determination of acid and only the reaction HCl+ NaOH NaCl+H2O takes place after the reduction of the ferric ion ends; therefore, if the alkali titration is performed again thereafter, the measurement of only the acid is exactly accomplished at the equiv. point of the 1st stage and the ferrous ion reacts to FeCl2+2NaOH Fe(OH)2+2NaCl in the titration after the equiv. point of the 1st stage. The measurement of total iron ion is accomplished exactly at the equiv. point of the 2nd stage.

Title: Manufacture of electrode plate for lead storage battery
Inventor: TOKUNAGA AKIO
IPC: H01M4/57
Filed: 1981-09-30
Abstract: PURPOSE:To increase the initial and the life performances of an electrode plate for a lead storage battery by making the plate by pressing and molding mixture, which consists of a lead oxide pwoder and micro-capsules containing an acid- proof binding agent, over a grid. CONSTITUTION:Lead dioxide powder manufactured by electrolytic oxidation, a lead oxide, is added with 1% of micro-capsules prepared from both a binding agent principally consisting of an unsaturated polyester resin, and casein used as a film-forming matter. A positive plate is made by packing thus prepared mixture into a grid, and subjecting the grid packed with the mixture to pressure formation. As a result, since the micro-capsules are broken with pressure during the above pressing work, the above binding agent princiaplly consisting of an unsaturated polyester resin flows out of the capsules, and intrudes among the lead-dioxide particels. At the same time, the above resin hardens due to the catalytic function of the above lead dioxide, and reinforces the bindings between the particles. Consequently, the positive plate can be made to have a high initial performance and an excellent life performance.

Abstract: PURPOSE:To make decompression operation in a pressure reducing piston performable even in time of trouble happening in a pump, by energizing the pressure reducing piston to the master cylinder hydraulic pressure side with a spring all the time. CONSTITUTION:A pressure reducing piston 101 of an actuator 100 is always energized to the hydraulic pressure side of a cut valve 104 or a master cylinder.

Each of solenoid valves 120 and 121 is controlled for their opening or closing whereby decompression and reapplication of pressure of braking pressure are controlled. And, sufficient high pressure is not produced in the power circuit 22 till the pump reaches a steady discharge state, but the pressure reducing piston 101 is situated in a normally preparatory position with energizing force of the spring 120 so that decompression is made possible even when the pump is before the steady discarge state or it is out of order.

Filed: 1980-11-07
Abstract: PURPOSE:To reduce defects of a wafer and to precisely inspect the wafer by providing a scattered electron shielding plate having a hole at the part to be emitted with an electron beam on a sample. CONSTITUTION:A wafer 4 is placed on a horizontally movable base 5, and a scattered electron shielding plate 8 is disposed in the vicinity of the wafer 4 on the wall of a sample chamber 6. An element observing hole of the wafer 4 is opened at the electro-optical center of the plate 8. An electron beam 2 passes through a hole to emit the element. Even if scattered electrons 3 are produced at this time and are reflected on the lower surface of an electromagnetic lens 1, they do not reach the wafer 4 via the plate 8, secondary electrons emitted from the wafer 4 are exhausted from the hole of the plate 8 to be collected by a secondary electron detector 7. With this structure, no element is damaged by the scattered electrons, and IC wafers 4 to be produced will increase. Since the wafer can be observed at high electron beam accelerating voltage, its resolution is enhanced and can be precisely inspected.

Abstract: PURPOSE:To accurately decide a pulse signal by a simple constitution and to easily form an integrated circuit by connecting a decision part consisting of a diode and a pull-up resistor between the output side of a pulse input part and the output side of a constant voltage part. CONSTITUTION:A pulse signal inputted from the pulse sending side to the pulse input part 1 is rectified and smoothed by the constant voltage part 3 and a DC voltage is inputted to a power supply input part 5 as the power supply of a control part 8. The DC voltage is impressed also to one end 9 of the pull-up resistor 13 in the decision part 11. In this case, the voltage on the side 4 of the input part 1 is changed with the lapse of time, and when the voltage is higher than the DC voltage, the voltage value of an intermediate point 14 goes the same potential as the DC voltage because of the existence of the diode 12 and the DC voltage is impressed to a signal input part 6. When the voltage of the input part side 4 is lower than the DC voltage, the DC voltage is not impressed to the input part 6. The control part 8 executes the data processing of a pulse signal in accordance with the difference of the voltage value from that of the input part 6 and a control signal is outputted from a control signal output part 7 to the load side by using the output of the constant voltage part 3 as a power supply. Consequently, the pulse signal can be accurately decided and cost can be reduced.
