Title: Fluorescent lamp and display device using it
Inventor: NAKAMURA TOSHIYUKI
IPC: H01J61/94
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To facilitate the fabrication and heighten the light output. SOLUTION: A reflection surface consisting of particulates of a metal oxides film is formed on the inner surface of a light emitting chamber 6, and a phosphor film 18 is formed on the surface of the reflecting film 17. Accordingly ultraviolet rays generated by electric discharge are reflected many times by the reflecting film 17, and each time of light incidence and reflection, the ultraviolet rays pass through the phosphor film 18 to energize the phosphor film 18, so that the light output can be heightened. Because the reflecting film 17 consists of particulates of metal oxide in which titanium oxide, alumina, etc., is included, easy formation is assured, compared with the conventional arrangement which uses a metal evaporation process.

Title: Water treating adsorbent
Inventor: TAJIMA HIROKUNI
IPC: B01J20/24
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a water treating adsorbent excellent in ability to adsorb impurities or an effective component in water, easily desorbing adsorbed components and capable of recovering and recycling an adsorbed component by substituting carbamate groups for hydroxyl groups of cellulose at a specified degree of substitution and using the resultant cellulose carbamate as a carrier. SOLUTION: This adsorbent for water treatment uses cellulose carbamate as a carrier and the cellulose carbamate is obtd. by substituting carbamate (-O-C-O-NH2 ) groups for hydroxyl groups of cellulose at a degree of substitution of 0.05-0.45. Since the cellulose carbamate maintains hydrophilic property peculiar to cellulose, is excellent in ability to adsorb heavy metals, enzyme, etc., and attains easy desorption and regeneration, it functions effectively as a carrier for removing and recovering heavy metals or dyes in waste water or for fixing enzyme.

IPC: H01L23/522
Filed: 1984-12-13
Abstract: PURPOSE:To enable high yield capable of corresponding to the increase in density of the titled device and having no step cuts of metallic wirings and less electrical damage, by a method wherein both wet etching and anisotropic dry etching are used to process the insulation layer. CONSTITUTION:An insulation layer 5 using an organic polymer material e.g. polyimide is formed on the semiconductor device having the first layer metallic electrode 3 and the first metallic wiring 4. Next, a layer 7 serving as the mask to process the shape of the insulation layer 5, such as contact formation, is formed, and the mask layer 7 is processed in shape and then wet-etched. At this time, a contact hole is tapered and successively dry-etched e.g. by reactive ion etching. This results in the complete removal of the insulating material on the metallic electrode 3. Finally, the formation of contact holes is finished by etching away the mask layer 7. After contact hole formation, the second layer metallic wiring 6 is formed.

Title: Multi-color stamp
Inventor: GOTO KAZUMI
IPC: C09D11/00
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To present a rich expression of stamp-forming marks, and implement multi-color stamping even in complicate marks without detriment to its continuity by occluding two or more inks in a porous printing body of a rubber elastic body, forming each ink with at least a vehicle and coloring material, and allowing the vehicle to be the same irrespective of the color. SOLUTION: Two or more inks are occluded in a porous stamping body having a unit rubber elasticity, and each ink consists of the same vehicle, different coloring materials, and the coloring materials including only a pigment or a combination of a pigment and dye. As such, the deposition of ink solidified part, coagulation of the pigment, and the like can be precluded in the ink color surface even in the case where these are occluded together in a porous stamping body having a unit rubber elasticity. Accordingly, vivid stamp-forming marks can be maintained for a long period of time, and the stamp-forming marks can be rich with multi-color, thus forming complicate marks without detriment to the continuity of the marks.
