IPC: C08G59/00
Filed: 1980-04-22
Abstract: PURPOSE:To obtain a resin for lenses with high workability by reacting a copolymer of a monomer having a specified structural formula and a resin monomer having a specified range of refractive index and Abbe's number with an epoxy resin curing agent contg. halogen. CONSTITUTION:A monomer having a structural formula represented by the formula (where each of X, Y, Z and R2 is H, halogen or alkyl and R1 is alkyl) is copolymerized with a resin monomer having 1.55-1.65 D refractive index and >=40 Abbe's number. This copolymer is then mixed with an epoxy curing agent contg. halogen and having a high refractive index, and the mixture is injection-molded and heated to cause secondary curing. The resulting plastic lenses can be reduced by about 40-50% in thickness as compared to conventional lenses, and they have high workability and are easily used as lenses for glasses.

IPC: H01L23/50
Filed: 1989-03-06
Abstract: PURPOSE:To thoroughly remove a runner and a gate remaining on a resin main body by a method wherein a plating film small in adhesion power to resin is formed on the part of a lead frame corresponding to a resin injection path. CONSTITUTION:A semiconductor element (not shown in a figure) is mounted on a die pad 12 of a lead frame 10, the semiconductor element is connected to the tips of inner leads 18 through wire bonding, and the semiconductor element and the leads 18 are sealed up with resin through a usual method. As a resin injection path is formed at the parting faces of a cope and a drag of a molding die, a runner 30 and a gate 32 are left on a side rail 16 of the lead frame 10. Then, a plating film A small in adhesion power to resin is formed on the part of the side rail 16 where the runner 30 and the gate 32 are attached. Therefore, when the runner 30 and the gate 32 are removed by bending them in a direction that they are separated from the face of the frame 10, they are prevented from remaining attached to the surface of the frame 10.

Abstract: PURPOSE:To lead efficiently the light emitted from a light emitting element pellet to an optical fiber by forming a transparent body, which faces the light emitting element pellet arranged in an element arrangement part of a stem, so that the center part of this body has a plane disc shape and the peripheral part is thinner according as going father from the center of the transparent body. CONSTITUTION:A light A2, which is reflected by a paraboloidal reflective plate 12, of the light from a pellet 10 is made incident approximately vertically to a plane disc-shaped part 13p of a transparent body 13c, and a light which is not reflected by the reflective plate 12 and is made incident to the plane disc-shaped part is made incident to an optical fiber 19 without bending the optical path. A light A1 going to the peripheral part of the transparent body 13c of the light which is not reflected by the reflective plate 12 has the optical path bent in the direction of the optical axis of a convex lens part in the peripheral part in this convex lens part. Since the focus of the convex lens part is near the p-n junction part of the light emitting element pellet 10, the light transmitted through the convex lens part is made incident to the optical fiber 19 approximately vertically, and thus, the light of the light emitting element pellet 10 is led effectively to the optical fiber 19.

Title: Pigment fixing element
Inventor: TSUKAHARA JIRO
IPC: G03C8/24
Filed: 1992-02-06
Abstract: PURPOSE:To prevent discoloring of organic pigment that may be caused by the light in forming images by means of transfer of the pigment by containing a specific hydrazine derivative in a pigment fixing element. CONSTITUTION:A pigment fixing element contains a hydrazine derivative expressed by the formula. In the formula, R1-R4 independently represent a substitutional or non-substitutional alkyl grop, a cycroalkyl group, an alkenyl group and an aralkyl group and in this case R1-R4 may be coupled together to form a ring. The ring is a non-aromatic heterocyclic ring, and among atoms forming the ring, those belonging to R1-R4 must all be carbon atoms. The hydrazine derivative is thus synthesized by alkylating hydrazine hydrate in sequence. Alkylation is carried out by a direct method in which alkyl halide and sulfonic alkyl groups are employed or a reducing method in which a carbonyl compound and cyanoboron sodium hydride are employed.

Abstract: PURPOSE:To improve yield and quality by injecting wash water from a pair of oppositely arranged nozzles and making wash water to collide and making a turbulent flow generated abut against the surface of a substrate to be washed positioned on the sides of the nozzles and washing the surface of the substrate. CONSTITUTION:A pair of nozzle 10, 10' are disposed oppositely, wash water is injected simultaneously from a pair of the nozzles and made to collide and a turbulent flow generated is made to abut against the surface of a wafer 11 positioned on the sides of the nozzles and the surface of the wafer is washed.

The turbulent flow represents a spiral vortex, etc., the direction of a water current made to collide by the positioning of the wafer 11 on the sides of the nozzles is changed to the side, and the water current collides with the surface of the wafer by a certain hydraulic pressure. Consequently, wash water in the fine deep electrode window 6 is exchangeed, and the inside of the window is washed. Accordingly, the yield and quality of an IC are improved.

IPC: E02D19/12
Filed: 1990-03-05
Abstract: PURPOSE:To execute excavating work in a short term at a low cost without using any particular mechanical equipment by removing a sandy component of underground water, pumped up from a pumping up well, through a sedimentation basin, and thereafter allowing the water to penetrate by its own weight in a free underground water layer outside water shield wall. CONSTITUTION:Excavating construction work is performed while pumping up underground water from a pumping up well 2 by a submerged pump 4, and the pumped up underground water is drained to a drainage channel; 8 through a sedimentation tank 12. The underground water, accumulated in the drainage channel 8, penetrates by own weight a free underground water layer 5 outside water shield wall 1 from the internal surface of a groove 9. Since penetrability of the underground water, which penetrates the free underground water layer 5, is decreased smaller than that of the original ground, the underground water of an amount or more, recirculated to an excavation hole side, is pumped up by the submerged pump. In this way, underground construction work can be performed under a dry condition by dropping a level of free underground water to L' in the inner and outer of the water shield wall 1.
