摘要： PURPOSE:To prevent cracks and obtain efficient work by integrally forming a face glass and a spacer glass with heat molding, and chamfering the end face sealed to an anode plate. CONSTITUTION:A glass plate 3 is set on a lower mold 2 and an upper mold 1 is set thereon. A glass chamfering section 4 is previously provided at the corner of the lower mold 2 corresponding to the sealed portion on an anode plate side. This forming mold is given pressure and heat. At this time, the glass plate 3 is softened, fluidified and thrusted by the upper mold 1, resulting in a molded glass plate 3. At the lower mold 2 where the chamfering section 4 is provided, chamfering is also performed upon molding a cover glass, so that a cover glass 5 can be obtained which is chamfered inside the sealed portion on the anode plate side. There is therefore no need for chamfering by polishing the cover glass.

摘要： PURPOSE:To improve the shrinkage anisotropy of a plastic molded product and to enhance the strength of the weld of the plastic molded product by providing a shape wherein at least two thin pieces are bonded in a vertical state. CONSTITUTION:Compressed air is introduced between an upper mold guide frame 3 and an upper mold 1 through the compressed air introducing port 8 of the upper mold guide frame 3 and sprayed to a molded filler base material 11 through the compressed air supply port 16 of the upper mold 1 to press the same downwardly. By this method, the filler base material 11 is released from the upper mold 1 and broken between the adjacent recessed parts 14 of the upper mold 1 at the same time and formed into a small piece to prepare a filler. By repeating this compression molding, a large number of fillers are obtained. This is, each of fillers 21-24 has such a shape that at least two thin pieces are bonded in a vertical state. When the fillers thus obtained are mixed with a plastic molding base material to perform molding, the shrinkage of a molded product has isotropy without being biased to one direction and the plastic molded product not lowered in the strength of the weld thereof can be obtained.

摘要： PURPOSE:To obtain a quartz glass molding vessel wherein moldability and yield of a molded article are improved by coating silica sol-silicon carbide slurry on the surface of a molding vessel made of graphite. CONSTITUTION:Silica sol-silicon carbide slurry is coated on the surface of a molding vessel made of graphite which is used to obtain a molded body having a required shape by pressurizing and molding quartz glass at high temp. Then a silicon carbide layer is formed on the surface of this molding vessel by heat- treating the molding vessel coated with this slurry. In order to prepare the used silicon sol-silicon carbide slurry, preferably ion-exchange water is firstly added in reactive equivalent to organic silicon e.g. silicon compd. forming silica sol by hydrolysis such as tetraethoxysilane to form silica sol slurry. Then high- purity beta-silicon carbide fine powder is added to this slurry in the range of Si(OH)4/SiC=1.0-0.10 molar ratio to obtain silica sol-silicon carbide slurry.

摘要： PURPOSE:To form an optically good convex surface readily, by preforming a glass material using a forming mold having air vent holes in the central contact surface part and forming the optical surface of the lens. CONSTITUTION:A glass material 1 is prepared by cutting out a planar flat glass having both ground surfaces with a cutter and placed between molds 2 and 3, which are heated to a temperature required for forming and moved in the direction for compressing the glass material 1. Thus, the glass material 1 is deformed and formed by pressurization. The formed glass material 1 is then pressed to a state in which the central parts of both surfaces thereof enter air vent holes a little to complete the preforming in the shape of the glass material 1 having slight protruding parts 8. The resultant preformed glass material 1' is then fed between mold 4 and 5, which are heated to a temperature near the softening point of the glass to pressurize and form the glass material 1' and give the aimed lens having the desired shape.

摘要： PURPOSE: To obtain a material for forming die glass having superior parting characteristic for glass by forming a uniform parting layer for glass on the whole surface of a metallic forming die.
CONSTITUTION: A uniform parting layer for glass is formed on the whole surface of a metallic forming die such as Ni, then softened glass by heating is formed by press-contacting the softened glass closely to the forming die material. Thus, a forming die material which is striped easily from a formed product is obtd. The above-described parting layer is preped. by heat-treating the metallic forming die together with carbon powder to form a carbide layer, then cooling slowly, thus forming a layer wherein fine free carbon or carbide is present on the surface of said forming die in the form of a single substance or a compound body.
