Title: Fluorescent display tube
Inventor: AKANUMA MASANOBU
IPC: H01J31/15
Filed: 1979-06-25
Abstract: PURPOSE:To obtain a display tube having excellent brightness characteristics without almost changing the conventional manufacturing process by using a conductive material having a colour other than black and mirror surface structure as an anodic  segment surface. CONSTITUTION:A silver paste, etc., is screen-printed on the glass base plate 15 and then baked to form the wiring electrode 16 of a given pattern, and then a low- melting glass paste composed primarily of tin oxide is screen-printed on the wiring pattern and then baked to form the insulation layer 17. In this case, the insulation layer 17 is so formed that it is partially exposed and the through hole electrode 18 is formed on the partially exposed portion. Then, the anodic glass base plate is introduced into a vapor deposition apparatus where aluminium vapor-deposited film 19 is formed on the plate. Then, a bluish green fluorescent paste is screen-printed on the segmentary aluminium electrode 19 and then baked to form the fluorescent layer 20. Thus, without almost altering the conventional manufacturing process, a fluorescent display tube having excellent brightness characteristics can be obtained.

Title: Sintering operating method
Inventor: SATOU KAZUHIKO
IPC: C22B1/20
Filed: 1983-05-10
Abstract: PURPOSE:To eliminate the irregularity in sintering operation caused by the segregation in the particle size of the stock material in an ore storage tank, by successively applying difference in level in a stock material holding level from a tank high in said level to a tank low therein while controlling the delivery amount of each ore storage tank so as to retain the difference of the stock material holding levels between adjacent ore storage tanks in the order of the difference in level thereof in a constant range. CONSTITUTION:Main stock materials used in preparing a sintered ore are mixed and granulated while delivered from a plurality of ore storage tanks and the resulting granulated mixture is sintered. In this case, staircase like level difference is imparted to the stock material holding levels of a plurality of the ore storage tanks. For example, the level difference is imparted from max. 100% to min. 30%. In this state, the delivery amount of each ore storage tank is regulated so as to retain each level difference in a constant range without charging the stock materials into the ore storage tanks. When each level reaches a definite lower limit level, the stock materials are charged into the ore storage tanks at a constant speed up to a full amount.

Title: Fuel feeding device for engine
Inventor: OKINO YOSHINORI
IPC: F02D41/00
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the fuel injection through the first fuel injection valve from being impaired by the pressure in a cylinder by performing the fuel injection only through the first fuel injection valve injecting the fuel directly into the cylinder when the injection completion timing is relatively early. CONSTITUTION:The first fuel injection valve 11 injecting the fuel directly into a cylinder is provided on each cylinder of an engine 1, and the second fuel injection valve 12 is provided on an intake passage 13 communicated to the intake port 7 of each cylinder. A control unit 22 calculates the injection completion timing and the timing when the pressure in the cylinder affecting the first fuel injection valve 11 becomes the preset pressure at least not exceeding the injection pressure and compares both of them. When the injection completion timing is relatively early, the fuel injection is performed through only the first fuel injection valve 11, when the injection completion timing is later than the preset timing, the fuel injection is performed through only the second fuel injection valve 12 or both fuel injection valves 11, 12. Accordingly, the fuel injection through the first fuel injection valve 11 is prevented from being impaired by the pressure in the cylinder, and the adequate fuel injection is performed.

Title: Plasma display device
Inventor: ISAMOTO KEIJI
IPC: H01J11/34
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To reduce light leakage without restraining fluorescent coating and electrode material and improve brightness by providing a regressing/reflecting means on the back surface side than a cavity and returning light leaked to the back surface side of light generated in the cavity to a pixel. SOLUTION: By adhering piled thin sealing glasses 6 via a transparent encapsulating resin 7 on a prism board 5 which has cube (prism) shaped patterns arranged along pixel arrangement direction on its surface, a regressing/reflecting layer 3 is formed. The encapsulating resin 7 is a material with a refractive index more than that of a prism plate 5, and using back surface glass board 2 formed, in such way a display panel is constituted. Light which leaked to the back surface side of light generated in a cavity 17 is reflected by a regressing/reflecting layer 3 twice or four times and returns in the original direction. This can improve the outgoing efficiency to a front surface and the brightness of a plasma display device 1. If a pattern pitch of the regressing/ reflecting layer 3 is set shorter than thickness of a bulkhead 13, reflected light will not return to different pixels.
