Filed: 1979-08-23
Abstract: PURPOSE:To obtain a cathode ray tube for display light source, good color light and contrast under the daylight by constituting its face glass with color glass whose color is the same as or similar to the luminous color of the fluorescent surface. CONSTITUTION:A negative potential, with respect to the potential of a negative electrode 7, is applied to a grid 8 and a prdetermined level of current is applied to a heater 6 to heat the negative electrode 7 so that the voltage of the grid 8 is made closer to the potential of the negative electrode 7. This causes electron beams 10 to be emitted from the negative electrode 7 toward a fluorescent surface 2. In this case, the beams 10 are irradiated to the fluorescent surface 2 as nonfocusing beams. As a face glass 3 is employed color glass of a color corresponding to an intended luminous color.

Title: Transfer molding method and mold therefor
Inventor: OSADA MICHIO
IPC: B29C45/02
Filed: 1984-05-28
Abstract: PURPOSE:To prevent the generation of void by a method wherein air or water trapped in molten resin is expelled through a gap with the path of movement of said molten resin blocked when the resin material in a pot is subjected to pressure and fusion by means of a plunger. CONSTITUTION:A lead frame E is set in a cavity 6 and a top force 1 is locked to a bottom force 2, and a reciprocating mechanism 11 goes into operation to move a screening member 10 to the side of a runner 9 for the runner 9 to be prevented from intercommunication. A process follows wherein a resin material F is fed into a pot 3. The resin material F is then heated up to a required temperature whereafter it is fused under pressure exerted by the pressing tip 41 of a plunger 4. The fusion of the resin material F starts at cull 7 whereat heat collects more than at other portions. The resin material F now molten cannot travel though under pressure so far as the B side of the cavity 6 because of the screening member 10. Under such circumstances, pressure upon the resin material F in the pot 3 is allowed to build, expelling air or water trapped in the pot 3 or the resin material F itself through a gap between the pot 3 and the the pressing tip 41. This method ensures the prevention of the formation of void inside or outside the molding material.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To produce a mullite-SiC mixture by adding a carbonaceous material to an alumina-silica refractory material and carrying out heat treatment. SOLUTION: The Al2O3 and SiO2 in an alumina-silica refractory material are allowed to react with each other to form mullite and an excess of SiO2 over SiO2 in the composition of mullite is reduced to SiC with C in a carbonaceous material in an atmosphere of argon. The alumina-silica refractory material is first comminuted, powder of the carbonaceous material is added and they are intimately mixed and heated. The alumina-silica refractory material may be a natural mineral such as agalmatolite or clay. The carbonaceous material may be natural graphite, artificial graphite, coke or the like and the amount of the carbonaceous material added depends on the amount of silica in the alumina-silica refractory material. The carbonaceous material is added by an amount sufficient to reduce all the excess SiO2 to SiC.  The heating temperature is 1,450-1,550 deg.C and diluted carbon monoxide or argon is preferably used as the atmosphere. A low-grade mineral unusable as a material of refractories can be effectively utilized.
