Title: Electrode of electronic part
Inventor: INOUE KIYOSHI
IPC: B22F7/04
Filed: 1990-02-08
Abstract: PURPOSE:To rid an electrode of ion migration and lower its cost by using an electrode raw material of metal aluminum to which 0.1-10wt.% of boron nitride and 0.01-5wt.% of glass frit (lead borosilicate glass) are added. CONSTITUTION:Metal aluminum is used owing to its property of forming a thin oxide film on the metal aluminum surface even at over melting point (667 deg.C) and not being oxidized further in the inside of the metal as well as the property of not being subjected to metallic coagulation at a temperature over the melting point due to the formation of the surface oxide film and keep the shape as an electrode. In order to improve adhesion strength of metal aluminum to a ceramic element and have ohmic contact with the element an electrode raw material consisting of 0.01-5wt.% of glass frit (lead borosilicate glass) and 0.1-10wt.% of boron nitride is used, electrode raw material is sintered at 850-900 deg.C in air. In this way by means of an aluminum electrode using economic raw material, capable of being sintered in air and having ohmic contact with ceramic, danger of ion migration is eliminated and low cost may be secured in comparison with a silver electrode.

Title: Flat plate type light emitting device
Inventor: MATSUDAIRA TSUTOMU
IPC: G02F1/1335
Filed: 1990-02-07
Abstract: PURPOSE:To uniformize the light of a light emitting surface and to eliminate the unequalness by applying a florescent material on the surface of a diffusion plate or light transmission plate. CONSTITUTION:The fluorescent material is applied on the surface of the diffu sion plate 1-1 or light transmission plate 2-1 by decreasing the amt. of the fluorescent material applied on the inside surface of a discharge tube or without applying this material at all. Since the fluorescent material is applied on the diffusion plate 1-1 or light transmission plate 2-1 in this case, the uniform appli cation is possible and, therefore, the fluctuation in the light emitting color and light emitting brightness by the unequal coating is suppressed. Since the amt. of the fluorescent material applied on the fluorescent tube 1-2 is small, mainly UV rays are emitted from the fluorescent tube 1-2 and since these rays are converted to visible rays by the fluorescent material on the surface of the diffusion plate 1-1 or light transmission plate 2-1, the loss of the light on the way is decreased. The unequal light emitting colors and brightness are eliminated with the simple constitution in this way and the extremely uniform colors and brightness are obtd. In addition, the light emitting efficiency is en hanced.

Title: Bleeding method
Inventor: TAKADA KAZUHARU
IPC: B01D1/30
Filed: 1979-03-13
Abstract: PURPOSE: To ensure the long life of an oil-lubricated vacuum pump by discharging water vapor while avoiding the generation of water drops by reducing the water vapor in partial pressure with air or the like mixed therein.  
     CONSTITUTION: About 30°C seawater is sucked into a vapor chamber 1 kept vacuum via a strainer 15, a water supply pipe 12, a flow meter 14 and a valve 13, and sprayed over a horizontal heat-conducting pipe bundle 3 by a crude water sprayer 2. The vapor whose temperature is raised through the compression of a compressor 10 is introduced into the pipes of the bundle 3, and the condensation water produced through heat exchange flows out through the pipes and accumulates in a distilled water reservoir 5. In the meanwhile, the gas containing water vapor does not produce water drops even when compressed by an oil-lubricated vacuum pump 17 since the partial pressure of the vapor is lowered by the air mixed therein passing through the inlet 18 of an air ejector 16. Therefore, a pump becomes free from corrosion and lubricating oil aging and comes to have a long life.

IPC: F16C32/06
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To solve a problem in a fluid bearing device by which a rotary shaft is journaled by fluid pressure, that the bearing clearance of a land part for supporting the rotary shaft by dynamic pressure is narrow, thereby exothermic action occurs at the time of high speed rotation, the rotary shaft and a bearing member are locally thermally expanded in this land part, and finally seizure occurs. SOLUTION: Bearing clearances d1, d2 are so arranged that the bearing clearance d1 between a dynamic pressure generating land part 14 and a rotary shaft 20 is set larger than the bearing clearance d2 leading from static pressure pockets 6, 7 to a drain groove 10. Preferably, the bearing clearance d1 is set to be from 1.3 to twice the bearing clearance d2. Hereby, an exothermic action amount in the land part 14 can be suppressed even at high speed rotation, therefore seizure can be prevented.

Title: Molding of compressed powder form
Inventor: SAGAWA MASATO
IPC: B29C43/02
Filed: 1995-01-26
Abstract: PURPOSE: To make it possible to mold a compressed powder form with a constant density of powder filled in a depth direction in a rubber mold, highly homogenized and free from a distortion, cracks or chips by supplying powder to the rubber mold through a guide member, and performing a filling step to fill the powder to a high density using a pusher, in a few rounds of operation. CONSTITUTION: First, an upper punch p2 is caused to descend to sit on the upper face d1 of a die (d), and a lid member 11 attached to the lower face of a backup plate 8 is caused to engage with a stepped part m2 provided on the opening of the rubber mold (m). Next, the upper punch p2 is lowered and this action allows the die (d) to descend with the punch p2, resisting a coil spring 7 assist-supported by the die (d). On the other hand, a lower punch p1 fixed to a machine table 4 through an auxiliary support plate 2 is immovable, so that the depth of a space where the rubber mold (m) is charged, i.e., a die cavity 1 is reduced. Consequently, a rubber cavity m1 contracts inwardly, resulting in the compression of powder to a high density into a compressed powder form.
