Title: Optical information detecting device
Inventor: FUKADA SO
IPC: G11B11/105
Filed: 1996-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce cross talk by deviating cross talk of signals of an adjacent groove part and a land part from compensation conditions by performing optimum phase compensation for a land part and a groove part. SOLUTION: At the time of reproduction, reflected luminous flux of a groove part 20 or a land part 21 is divided into a transmission component and a reflection component by a polarization control function of an electric vector control mechanism 4 and a polarization beam splitter. States of all luminous fluxes- straight advance and reflection are set by a movable mirror 7 in the reflected component. When the mirror 7 is lowered, luminous flux is reflected, it is compensated by a half wavelength plate 8 with some optical phase difference as for detecting a light signal recorded in a groove 20, and divided into a transmission component and a reflected component by a polarization beam splitter 9.  When the mirror 7 is raised, luminous flux is passed through, and it is made for detecting a signal recorded in a land 21, and is compensated by a half wavelength plate 14 with optical phase difference differing from the groove 20, and divided into a transmission component and a reflected component by a polarization beam splitter 15, and they are outputted from differential amplifiers 22, 23.

Abstract: PURPOSE:To make it possible to use one kind of polishing chips for both coarse polishing and finishing polishing, by heating and melting a mixture of a thermoplastic material, an organic filler and a volatile material to form the mixture into a rope-like shape, and by cutting the same into pellet-like pieces. CONSTITUTION:A mixture of a thermoplastic material, an inorganic filler and a volatile material is fed into a hopper 2 in an extruder 1 and is then extruded from dies 3 so that the mixture is turned into a rope-like shape. The extruded rope-like mold product 4 is introduced into water 6 in an water tank 5 for cooling. Since at this time the rope-like product 4 is in a condition which is just after extrusion by the dies 3, the moisture component in the product 4 is evaporated so that a foamed structure is formed. The rope-like product 4 is taken out from the water 6 after cooling, and is then cut by a cutter 7 into pellet like chips 8. Each chip 8 is formed on its outer peripheral surface with a skin layer 10 having fine wrinkling like unevennesses, and has its front and rear cut faces from which the foamed structure is exposed so that air pores 13 are opened to form coarsely uneven surfaces 12. By using these chips having the above-mentioned finely uneven surfaces 11 and coarsely uneven surfaces 12, both coarse polishing and finishing polishing may be simultaneously conducted.

Title: Manufacturing method for semiconductor luminous device
Inventor: HIGUCHI HIDEYO
IPC: H01S5/00
Filed: 1978-07-14
Abstract: PURPOSE: To harden the ultraviolet curing resin making a contact with a light focussing medium by temporarily attaching the light focussing medium attached to the luminous portion of a semiconductor luminous element to one end of a light transmission path and after light system alignment by radiating the ultraviolet ray from the other end of the transmission path.  
     CONSTITUTION: Polyacrylate 7 is coated on the output end face of a laser 1 for covering the luminous portion therewith, and the laser 1 is aligned with the light axis of a light transmission path 2 with a ball lens 3a temporarily fixed to the input end. The axis alignment between the transmission path 2 and the ball lens 3a is achieved by etching the core portion at the input end of the transmission path into a dish shape and thereafter by inerting the ball lens into a chip board. The temporary fixing is achieved by making use of surfacial tension of the pure water. Successively the closed contact between the lens 3a and resin 7 is maintained by forcing the lens 3a to the laser end face to approach a position with a maximum joinning efficiency. The violet ray is irradiated to the intermediation between the luminous portion and the lens through the transmission path 2 to harden the resin. Thereafter, when the transmission path may be separated from the laser end face, the lens would make a contact with the laser end face, maintaining the condition wherein the luminous portion is aligned with the light axis.

Title: Oil draining method of oil-free screw compressor
Inventor: MORI HIDETOMO
IPC: F04C29/02
Filed: 1995-04-12
Abstract: PURPOSE: To eliminate generation of a drain oil stirring loss due to a periodic gear by feeding the inside of an end plate with air by way of an equalizing passage from a speed up gear, and discharge air bubbles in drain oil at an exhaust collecting part where a drain oil flow velocity is slow. CONSTITUTION: Air being stirred by two periodic gears 5 and 6 rotating at a high speed and mixed in drain oil and made flowing away into a speed up gear from the inside of an end cover 22, is returned to the inside of this end cover 22 again by way of an equalizing passage connecting the speed up gear and the end cover 22. Accordingly, pressure in the speed up gear will not go up at all, and a pressure differential between the end cover 22 and the speed up gear inward is kept in minuteness. In addition, a passage area of a drain oil collecting part 35 of the end cover 22 is so formed as to have that several times over the area of an discharge port 36. Therefore, a flow velocity of the drain oil at this drain oil collecting part 34 comes to the value ranging from one-several to one-tenth or so to that in a discharge pipe, namely, a buoyancy working on an air bubble grows larger than a drag working on the air bubble mixed in the drain oil, whereby the air bubble is floated up, separating from the drain oil.
