Title: Manufacture of color cathode ray tube
Inventor: FUKUNISHI TOSHIAKI
IPC: H01J29/02
Filed: 1988-04-19
Abstract: PURPOSE:To eliminate a stress relief heat treatment and improve a withstand voltage characteristic by welding first-fourth spring clips to a frame before a blackening treatment process is applied, and welding the fourth spring clip to the washer in which an through-hole is formed after the blackening treatment process and a pair set process. CONSTITUTION:In a pair set process, the positioning of a shadow mask 2 is made with first third spring clips 4 in which the through-hole 4b having the size insertedly attached to first-third panel pins, is formed, and then a fourth spring clip 4 is welded to a washer 10 insertedly attached to a fourth panel pin 9. Consequently a stress relief heat treatment is unnecessary. And the broken spalling of a blackening film is eliminated by applying a blackening process after first-fourth spring clips 4 is attached to a frame 3. Moreover the occurrence of a weld splash can be eliminated in the weld of the washer 10 to the fourth spring clip 4 by previously removing the blackening film of the weld part of the fourth spring clip 4.

Abstract: PROBLEM TO BE SOLVED: To provide a substrate excellent in surface flatness by mounting a truncated conical flexible film hollowed in the center on the circumference of a truncated conical washer so as to form a highly airtight space by the washer and the flexible film, and connecting an air feed pipe and an air pressure reducing pipe to an air passage provided on the washer. SOLUTION: A washer 6 has a small screw bore on the circumferential upper edge, and it is opened in the upper end. A flexible film 5 having a truncated conical circumference and hollowed in the center is mounted thereon to form a chamber by the bottom of the flexible film 5 and a washer bottom 6c. A flexible pipe 8 which forms an air passage usable by one as both a pipe for feeding pressure air and a pipe for reducing the pipe internal pressure is connected to an air passage 6d extending from the head of the washer 6 to the bottom 6a thereof. According to this structure, the pressure air is supplied to the chamber formed by the washer bottom 6c and the flexible film 5, whereby the flexible film 5 is expanded to form a pressurization chamber.  Therefore, a uniform pressure according to the surface state of the abrasive cloth of a platen can be transmitted to a substrate to enhance the surface smoothness of the substrate.

Title: Recovery of graphite from desulfurization sludge in ironworks
Inventor: MURAKI MITSUO
IPC: C01B31/04
Filed: 1984-05-15
Abstract: PURPOSE:Iron is separated from desulfurization sludge and the residue is subjected to floatation to isolate graphite and the graphite is treated with a mixture of hydrochloric and hydrofluoric acid to enable inexpensive recovery of graphite of high quality in high efficiency. CONSTITUTION:At first, the desulfurization sludge in an ironworks is crushed and separated into magnetic materials and non-magnetic materials. In general, crushing makes iron lumps, but non-magnetic slag powders. The crushed sludge is passed through a magnetic separator to recover the magnetic materials (iron). The non-magnetic mixture of graphite, calcite, silicic acid and so on is subjected to floatation to collect graphite. The floatation is carried out under alkaline conditions of 10.5 or higher pH. The graphite collected by the floatation contains small amounts of Fe, SiO2 and CaO, thus chemically treated. The floating fraction is sent to the leaching tank, to which HCl is added so that the pH becomes 0.2-0.5, further HF is added in such an amount as the amount corresponds to 0.5-1.0 equivalent to SiO2 to effect leaching. Then, the remaining is filtered, washed and dried to give the objective graphite.

Title: Method for sealing air filter
Inventor: IWASAKI NOBUO
IPC: B01D46/10
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent a sealing agent from dropping from an outer frame to soil a filter at the time of operation, and enhance the production efficiency of the filter, by specifying the allowable use time of a sealing agent prepared by combining a principal agent composed of polyol and inorganic filler with a curing agent with isocyanate groups. SOLUTION: As a polyol constituting the principal material of the sealing agent, a castor oil-modified polyol is used and as an inorganic filler, calcium carbonate is used. As a curing agent having isocyanate groups, for example, modified diphenylmethane diisocyanate is used. The initial viscosity of the sealing agent composed of principal agent and curing agent is adjusted to 2300 cP or less so that the viscosity thereof is held at 500-3000 cP for 1-15 minutes during which the sealing agent can be used. Thus sucking the sealing agent into a filter material can be limited so that the sealing agent is prevented from drooling from an outer frame, and hence a good external appearance can be provided and since the curing time of the sealing agent is short, production efficiency can be improved and a good injection work can be conducted.

Abstract: PURPOSE:To increase and uniformalize the contrast ratio over the entire part of a display surface by constituting a back electrode of parts consisting of high-reflectivity films and parts consisting of low-reflectivity films. CONSTITUTION:The back electrode 2 formed on a substrate 1 is so formed that the parts consisting of the high-reflectivity films 3, such as, for example, aluminum films, and parts consisting of the relatively low-reflectivity films 4, such as chromium films, coexist at proper ratios. The sizes of the high- reflectivity parts 3 and the low-reflectivity film parts 4 are the same as or smaller than the size of display picture elements. The low-reflectivity films 4 occupying the entire surface or a part of the respective surfaces of the parts 21 corresponding to the intersected points with the display electrodes of the back electrode consisting of, for example, an aluminum film are formed, when the back electrode consists of plural band-shaped electrodes 20 intersecting with the plural band-shaped display electrodes. Then, the films 3 having the sufficiently high reflectivity exist on the rear surface of a liquid crystal layer when the liquid crystal exists on a cholesteric layer and, therefore, the white light by scattered light is stressed.
