Title: Manufacture for hollow molded body
Inventor: HARADA KOHEI
IPC: B29C45/34
Filed: 1992-08-11
Abstract: PURPOSE:To provide a manufacture for a hollow molded product having the superior appearance which can shorten the molding cycle and prevent the generation of sinks, warps and flow marks, etc., on the outer surface of the molded product. CONSTITUTION:A solid needle-shaped member 52 is moved forward to reach a hollow part. 31 in a hollow molded product 3 within a cavity 13. Then, the needle-shaped member 52 is moved back thereby to form a thin hole 32 communicating with the hollow part 31 of the molded product 3. At the same time, a discharge path 53 is formed between the needle-shaped member 52 and the outer wall of the cavity 13 which allows no molten resin, but a pressured fluid to pass therethrough. A pressured fluid in the hollow part 31 of the hollow molded product 3 is discharged through the slim and thin hole 32 and the discharge path 53.

Title: Photocurable resin composition
Inventor: TAKEYAMA SHUICHI
IPC: G03F7/038
Filed: 1992-08-11
Abstract: PURPOSE:To obtain a resin composition which readily cures upon ultraviolet irradiation and suffers little cure shrinkage by mixing an epoxy resin with a cationic photopolymerization initiator, a silane coupling agent, and a given amount of a silica powder having a specific refractive index. CONSTITUTION:This resin composition is produced by mixing an epoxy resin component (A) consisting of a bisphenol epoxy resin and an alicyclic epoxy resin (e.g. vinylcyclohexene diepoxide) with a cationic photopolymerization initiator (e.g. p-chlorobenzenediazonium hexafluorophosphate), a silane coupling agent (e.g. gamma-glycidoxypropyltrimethoxysilane), and a silica powder having a refractive index of 1.54-1.56, the amount of the powder being 15-50 pts.wt. per 100 pts.wt. the component (A). When this composition is used for bonding lenses to a support therefor, the optical axis shifts little because the cure shrinkage of the composition is little.

In succession, a spatial filter is determined from the widths of the stripes and the standard deviation determined (S9) and a spatial filtering processing is executed for the above binary- coded image by the filter determined above (S10). Moreover, maximal stripes are extracted on the basis of a prescribed threshold value from the image subjected to the spatial filtering processing (S11), the maximal stripes other than those of prescribed sizes are removed from the extracted image (S12) and the area of the maximal stripes is computed from the remainders (S13).
