IPC: G03G15/04
Filed: 1989-04-13
Abstract: PURPOSE:To miniaturize a device, and to reduce cost by arranging an opposed reflecting surface to reflect the light beam of a light source toward the surface of a body between the light source and a light incident hole. CONSTITUTION:An optical path converting mirror part 8 opposed to a lens array 3 between the light incident hole 6 and a light outgoing hole 7 is installed, and the opposed reflecting surface 12 to reflect the light beam of the light source 11 toward the body surface 9 is arranged between the light source 11 near the body surface 9 and the light incident hole 9. By irradiating the body surface 9 directly by the light beam of the light source 11, and simultaneously, by reflecting the light beam toward the body surface 9 by the opposed reflecting surface 12 in this way, the body surface 9 can be illuminated, and since the opposed reflecting surface 12 is positioned between the light source 11 and the side of the light incident hole 6, the flare of the light source 11 csn be shielded by the opposed reflecting surface 12 itself, and the miniaturization and the cost reduction of the device can be attained.

Title: Method for producing dual grating
Inventor: SUMI TAKESHI
IPC: G11B7/135
Filed: 1989-04-13
Abstract: PURPOSE:To reproduce grating on substrate side by a method wherein the grating is produced at positions, which lie on one straight line intersecting the center of the circle of a stamper and are symmetrical with each other, in such a manner that the direction of the groove is parallel or normal to said straight line so as to be coated with ultraviolet-curing resin in order to be exposed to ultraviolet rays under the state that substrate is brought into close contact with the surface of said resin. CONSTITUTION:Grating 19 for front surface is produced at positions, which lie on one straight line 18 intersecting the center A of a stamper 17 installed on a rotary state and are symmetrical with each other, in such a manner that the direction of the groove of the grating is parallel or normal to the straight line 18. Laser beams emitted from a laser beam source 23 is irradiated over the grating 19 for front surface on the stamper 17. Only the stamper 17 is turned for fine adjustment so that reflected beams and diffracted and reflected beams reach to the straight line 30 described on a locus surface 29. Ultraviolet-curing resin 31 is applied on the grating 19 for front surface and, after that, a cover 21 is mounted over the stamper. Since a recess 22 is formed in the cover 21 at the part facing to the grating 19 for front surface, substrate 28 is positioned in the recess 22 so as to be brought into close contact with the ultraviolet-curing resin 31. By exposing the resin to ultraviolet beams under the state just mentioned above, the grating for front surface is reproduced in the substrate 28 side.

Title: Coated throwaway tip
Inventor: NAKAI HIROSHI
IPC: C23C16/34
Filed: 1986-04-22
Abstract: PURPOSE:To aim at the promotion of long service life in a tip, by performing coating treatment, commensurable to each cutting function of a cutting face and a flank, on the throwaway tip, and giving it wear resistance or damageproof and tipping resistance. CONSTITUTION:A monolayer and a compound layer of titanium carbide or titanium nitride or titanium carbide-nitride are formed at the cutting face side of a tip by means of a physical evaporation process. On the other hand, the first layer of the monolayer or the compound layer of these of titanium carbide or titanium nitride or titanium carbidenitride is formed at the flank side by means of a chemical evaporation process, and the outer layer side is formed by the physical evaporation process. Therefore, wear on a flank is little, while adhesive strength in a film on the cutting face comes so high, and service life in the tip is thus sharply prolonged thanks to a synergetic effect of these layers.
