Title: Device for converting solute sample into ionized molecule
Inventor: JIEIMUZU EI APUFUERU JIYUNIA
IPC: G01N30/72
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To ionize sample without using a flow distributer, and enable correct mass analysis by a small quantity of introduced solvent by moving a charged molecule in electric atomization through an aperture part in a housing to cross toward a second passage in the housing. SOLUTION: Liquid sample is introduced through a nebulizer having a passage 14, and it is discharged from an exit 15 of the passage 14 under conditions for forming electric atomization 11. Charged liquid is electrostatically pulled to an aperture part 17 laterally to cross a gap between the exit 15 of the passage 14 and the aperture part 17. Electrostatic attraction force is generated by providing plural voltage sources 16, 18 to device parts. The voltage source 16 and the voltage source 18 are respectively connected to a housing 19 containing a passage 22, and the passage 22. In the process of crossing the gap to get closer to an entrance to the passage 22, after passing an aperture part 21 in the housing 19, the electric atomization eliminates solvent controlled by cross flow of gas 20 from liquid drops, acting to leave charged liquid drops which are small.

IPC: G03G15/01
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To excellently supply toner to a developing device by making the lower end of an aperture part for supplying developer higher than a rotary carrying member in a rotary type developing device where development is executed at a position where a wall surface on which the aperture part for supplying the developer is formed is tilted. SOLUTION: In this rotary type developing device, a state where the wall surface on which the aperture part for supplying the developer is formed is inclined is set as a developing position, and positional relation between a toner carrying screw 11Y and the aperture part 30 of a toner hopper is regulated so that the lower end 301 of the aperture part of the toner hopper 2Y in such an inclined state is made higher than a horizontal plane passing the upper end of the outermost periphery of the rotational locus of the screw 11Y. The toner carrying screw is set to be buried under the toner T even when toner in the toner hopper flows out to a toner cartridge side at the developing position.

Title: Concentrated constant isolator
Inventor: TAKEDA SHIGERU
IPC: H01P1/383
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a high performance concentrated constant isolator by making the value of energy absorbing resistance larger than a characteristic impedance. SOLUTION: In the case of measuring this concentrated constant isolator of 1000MHz band by the measurement system of 50Ω, the frequency characteristics of an S parameter calculated by considering only the loss factor ΔH of garnet are obtained. In this case, the energy absorbing resistance is 50Ω. That is, the fact that reflection loss is in an optimum state in the measurement system of 50Ω means that it is stronger than an optimum magnetic field from the view point of opposite direction loss. Thus, when the incorporated energy absorbing resistance is made larger than the characteristic impedance, the problem is solved.  In such a manner, when manufacturing an isolator using a lossy concentrated constant circulator as a base, incorporating resistors and manufacturing an isolator, it is desirable to use the resistor larger than the characteristic impedance of the measurement system 1 to optimiz the reflection loss.

Title: Liquid crystal display device with back light
Inventor: KOGURE KAZUYA
IPC: G02F1/1335
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device with a back light of which lighting can easily be confirmed. SOLUTION: A back light 21 is arranged behind a translucent type liquid crystal panel 20. A switch 22 controls ON-OFF the back light, and a light emitted diode 23 flickers in response to ON-OFF of the back light 21. Therefore, it is possible to confirm the lighting state of the back light 21 through the light emitted diode 23 even in a well-lighted area. Since two driving signals of different duty ratios are selectively inputted to the light emitted diode 23, reduction of power consumption is attained by changing over the brightness of the light emitted diode 23 in accordance with the ambient condition.

Title: Transistor
Inventor: NAGURA HIDEAKI
IPC: H01L29/10
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the decline of current amplification degree consequent on concentration of current on the side plane of an emitter by providing an annular addition region of the same conductive type as of a collector region which surrounds a connecting part between a base electrode and a base region, in the base region. CONSTITUTION:In a base region 4, an addition region 6 of the same conductive type as of a collector region 2 is formed so that it surrounds a base electrode 7. By this constitution, a P-N junction is formed between said region 6 and the base region 4 and accordingly a depletion layer is produced around the addition region 6 which restrains the current injected into the base region directly from the side wall of an emitter 5. As a result, the main injected current flows out of the lower side of the emitter 5, thereby preventing the concentration of current on the side plane of the emitter and the resulting decline of current amplification degree due to the recombination in the surface condition of the boundary with an oxide film. Also, as the available emitter area on a constant chip area increases, the enhancement of collector saturation voltage and the decline of d.c. current amplification degree of large current can be reduced.

Abstract: PURPOSE:To produce a seamless steel tube having high strength, high yield ratio, and high toughness while obviating the necessity of quench-and-temper treatment by subjecting a master tube stock prepared by roughing a steel billet to heat treatment under specific conditions and then to finish rolling to the respectively prescribed outside diameter and thickness at the time of producing a seamless steel tube from a steel billet. CONSTITUTION:A steel billet as a stock for seamless steel tube is heated up to 1200-1250 deg.C and subjected first to piercing and then to roughing by means of a mandrel mill so as to be formed into a tube stock. This tube stock is previously cooled down to a temp. of the Ar1 transformation point or below and then reheated up to a temp. between the Ac3 point and (Ac3+50 deg.C), by which the structure is austenized. Subsequently, the tube stock is cooled again down to a temp. between (Ac3 point -30 deg.C) and (Ac3 point -100 deg.C) and finish- rolled to the desired diameter and thickness by means of a stretch reducing mill. By this method, the seamless steel tube excellent in strength, toughness, etc., can be produced while obviating the necessity of treatments, such as hardening and tempering.

A sensor operation confirmation execution unit 13 confirms whether or not the sensor operates normally. When the sensor is usable, a program restart part retrieval unit 14 determines the measurement restart place. Then an approach operation command unit 15 moves the sensor to the measurement restart place of the measured body. Then a program restart command unit 16 indicates the restart of a program and measurement is started at the measurement restart place.

Filed: 1983-10-26
Abstract: PURPOSE:To keep beam position within specified range of scanning position by a method wherein the drawing for specified frame is skipped according to the data on beam position in the shifting direction of a specimen rack to be drawn again later. CONSTITUTION:A lower limit beam value V2 is preliminarily set up a little bit inside the beam scanning range limit V0V2 selecting the value not to exceed V0V2 in the cell even if it exceeds V2. When the limit value 2 is excessive in an arbitrary cell, next cell is skipped as a not-yet drawn cell by this signal.

Any skipped cell drawing may be drawn again after drawing the frame before shifting to next frame or after drawing several frames or after drawing all frames.
