Title: Plastic lens
Inventor: NOMURA TAKAMITSU
IPC: G02B3/00
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To easily and surely detect a gate cross section part by forming the gate cross section part on the outer peripheral face of a flange part and a band-like glossy surface on the whole circumference except the gate cross section part. SOLUTION: A plastic lens is a lens about several mm in diameter used for an optical pickup, etc., such as a CD-ROM drive and has an optical function part 1 functioning as a convex lens in the middle part. A flange part 2, for mounting it on a holder on the drive side at the time of mounting the lens, is formed around the optical function part 1. A gate cross section part 3, from which a surplus part made on the gate position is cut, is formed in a part of the outer peripheral face of the flange part 2. All regions except the gate cross section part 3 on the outer peripheral face of the flange part 2 are made to be a glossy surface. Consequently, the erroneous detection that a scratched part is the gate cross section part 3 is removed and the gate cross section part 3 is easily and surely detected.

Title: Modified ethylene polymer
Inventor: KAKIZAKI TETSUJI
IPC: C08F255/00
Filed: 1982-10-12
Abstract: PURPOSE:A modified ethylene polymer good in moldability, adhesive property, and blendability, prepared by graft-modifying a specified ethylene polymer with vinyl acetate and having a specified vinyl acetate content and a xylene-insoluble portion. CONSTITUTION:A modified ethylene polymer prepared by subjecting an ethylene polymer of a crystallinity of 4-50% and vinyl acetate to a graft reaction and having a vinyl acetate content (including vinyl acetate initially contained, if any) of 5-70wt% and a boiling xylene-insoluble portion of below 1wt%. An ethylene polymer having a crystallinity exceeding 50% is not desirable as the above ethylene polymer because the diffusion of vinyl acetate is difficult during impregnation, and it is difficult to obtain a uniformly graft-modified polymer, whereas an ethylene polymer having a crystallinity of below 4% has poor moldability and so is undesirable.

Title: Production of printed wiring board
Inventor: MATSUBARA TAKAHIRO
IPC: H05K3/00
Filed: 1994-07-29
Abstract: PURPOSE:To make it possible to expose the wall face in a hole without deteriorating the accuracy of circuit width when the circuit of a printed board is formed by irradiating a UV light. CONSTITUTION:A thin transparent film 4 is sandwiched between a transparent plate 6 and a mask film 3 on the opposite sides of a copper clad laminate 1. A transparent liquid 5 is passed between the thin transparent film 4 and the transparent plate 6 and then they are pressed to project the mixture of the thin transparent film 4 and the transparent liquid 5 into a hole in the copper clad laminate 1. Consequently, a parallel UV light entering from each side is retracted and scattered to impinge on the wall face in the hole. Since a parallel light can be converted into a scattered light only at a required part, the accuracy of circuit width is prevented tram deteriorating.
