IPC: H01J9/227
Filed: 1989-11-16
Abstract: PURPOSE: To improve luminescence efficiency by mixing a specified amount of fluorescent powder to binder for phosphor paste, which is manufactured by cooling solution at an ambient temperature prepared by dissolving a specified amount of N.C. in BCA solution, and stirring the same. CONSTITUTION: While maintaining BCA solution(Butyl Carbitol Acetate solution) temperature of a glass vessel 9 in a water bath 4 at 75 deg.C+5 deg.C, and adding N.C.(Nitro Cellulose) in small amounts the solution is shakingly mixed, so as to dissolve by a mixing bar 2. Here the content of the N.C. is set to be 1.0 to 10.0 percentage by weight, the content of the BCA solution is set to be 99.0 to 90.0 percentage by weight, and when colorless transparent solution is formed by dissolving, the solution is gradually cooled at an ambient temperature. Phosphor paste is mixed and manufactured by utilizing a stirrer as adding phosphor powder in small amount in this binder for the phosphor paste. At this time, the approximate mixing ratio comprises 90.0 to 10.0 percentage by weight of binder and 10.0 to 90.0 percentage by weight of phosphor powder.  Thereby, a phosphor layer having a high luminescence efficiency can be obtained.

Inventor: HORIUCHI HIROSHI
IPC: H01M8/04
Filed: 1990-11-06
Abstract: PURPOSE:To avoid the reduction of the life characteristic due to gas deficiency worried when a load is abruptly increased without reducing the plant efficiency or increasing the installation area by providing a control means increasing/ decreasing the inlet pressure of the reaction gas according to the fuel cell operation mode. CONSTITUTION:The pressure of a pressure transmitter 7 connected to a fuel gas inlet manifold is controlled by a pressure adjusting valve 11 installed on a discharge side pipe 4.

Title: Analog/digital conversion device
Inventor: TANAKA SHUNJI
IPC: H03M1/10
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce noise at the time of non-signal in the PCM encoding transmission of sound by adding the lowest bit 1LSB to A/D conversion output, shifting data obtained by shifting the level of the non-signal time by 1LSB in an LSB direction by one bit and setting it to be data of 1/2. SOLUTION: A sound signal IN is inputted to an adder 30 and output is digitized in an A/D converter 10, is integrated in an integrator 20, and is fed- back to the adder 30. DC offset compensation is executed and the center value of a digital value is outputted at the time of non-signal. When non-signal voltage exists near input O, digital output fluctuates between coes 0000 and 1111. Then, digital output is added with 1LSB in an adder 40 and the whole is raised by 0001. Then, a characteristic is changed from a solid line to the state of chain line. Then, the characteristic is changed from the state of chain line to the state of a dotted line with the whole as 1/2 by shifting output to the LSB direction by one bit in the shifter 60 and switching the lowest bit. Thus, discontinuity around input O is reduced and noise output can be reduced.

Abstract: PURPOSE:To make a cassette mounting mechanism at a loading time minimum and to miniaturize a carrying system by dividing a cassette holder into a revolving arm part and a main body part and executing the expansion and contraction of the both parts with the moving operation of a slide chassis. CONSTITUTION:A main body part 20 and a revolving arm part 15 are turned in a counter-clock-wise direction and a cassette 6 is inserted with a cassette inserting port to be upward. Next, when the main body part 20 is pushed down in an arrow B direction, the engaging position of coupling pins 18 and 19 and through channels 16 and 17 are not moved, however, since a coupling pin 21 is passed through the inside of a guide channel 13, the cassette 6 is exactly positioned to a coiling reel 24 and a supplying reel 23. Next, when a slide chassis 11 is moved in a C direction, the engaging position of the guide channel and the coupling pin is not moved and obtained as a prescribed position. Thus, since the revolving arm part 15 and the main body part 20 are expanded and contracted by the moving operation of the slide chassis, the cassette mounting mechanism at the loading time can be made small.

Abstract: PURPOSE:To reduce a shock force applied to a die body at the time of removing a press residue and prevent damage to the die body by previously applying a mold lubricant to Al billet faces, a face of a die contacting with the billet, and a die ring face. CONSTITUTION:In the case that extrusion of Al stock by an extrusion device, extrusion is performed with a mold lubricant previously applied to faces of the Al billet or faces of an extrusion metal die directly contacting with the billet, that is, the front face of a die 1 and a die ring 4.

Abstract: PROBLEM TO BE SOLVED: To provide a sealing plate with an explosion-proof valve of high reliability by installing a hole having a diameter different from the diameter of an electrolyte pouring circular hole part for a cover in a seal plate, and covering the bottom of the seal plate. SOLUTION: A sealing plate is formed by installing an electrolyte pouring hole part 3 in a cover plate and covering the upper surface with a seal plate 4 having an explosion-proof valve. An explosion-proof valve hole part 4a is installed in the seal plate 4, and aluminum foil 4b is stuck to the lower surface of the explosion-proof valve hole part 4a. When the inner pressure of a battery is abnormally increased and an explosion-proof valve is worked, the aluminum foil 4b is swelled upward, then broken. The relation of the electrolyte pouring hole diameter of the cover plate and the explosion-proof valve hole diameter has large influence on the dispersion of valve working pressure.  The diameter of the explosion-proof valve hole part 4a of the seal plate 4 is made smaller or large than that of the electrolyte pouring hole part 3 of the cover plate, the broken position of the explosion-proof valve is limited when the explosion- proof valve is worked, and working pressure is stabilized.
