Title: Optical disk
Inventor: HAMADA MITSURU
IPC: G11B7/24015
Filed: 1986-03-03
Abstract: PURPOSE:To improve the heat resistance of the titled disk by using a substrate provided with a molded pregroup as the core material, forming a recording layer on the substrate, and then mounting a cover substrate consisting of an optically isotropic transparent resin through an inner peripheral spacer and an outer peripheral spacer to form the optical disk. CONSTITUTION:A disk substrate 9 provided with the pregroup 8 is formed by using a heat-resistant thermoplastic resin, and the recording layer 3 is formed thereon. Since the cover substrate 10 for protecting the recording layer 3 from humidity and dust, transmitting a laser beam 6 condensed by a lens, and projecting the beam on the recording layer 3 is needed, a disk substrate material such as polymethyl methacrylate PMMA and polycarbonate PC is used for the substrate 10. Consequently, the laser beam 6 is projected on the recording layer 3 of the disk substrate 9 without causing any birefringence. With such a structure, the cover substrate 10 having low heat resistance is supported by the disk substrate 9 which can be continuously used even at the high temps. of 150-200 deg.C, hence the deformation is controlled, and the heat resistance of the optical disk is improved.

Title: Surface hardening of aluminum and aluminum alloy
Inventor: KAMIMURA TADASHI
IPC: C22F1/04
Filed: 1990-02-28
Abstract: PURPOSE:To uniformly harden the surface of an Al material and to make improvement in wear resistance by irradiating the surface of the Al material with welding energy to form a molten pool and charging composite powder formed by coating ceramics particles with Al particles into this molten pool. CONSTITUTION:The Al particles 2 having the grain size of about 1/10 the grain size of the TiC particles 1 of about 50 to 200mu diameter are stuck to the TiC particles and the particles are centrifugally rolled for about 1 to 5 minutes in a vessel, by which the impact force by gaseous flow is applied to the particles. The composite powder 4 consisting of nuclei 1 of TiC enclosed with Al films 3 is thus previously produced. An Al alloy casting 5 is then set to a TiG welding device and the surface to be hardened thereof is disposed to face a welding torch 8. While the welding torch 6 is moved in a direction A, the surface is irradiated with an arc and is thereby heated and melted to form the molten pool 9. The above-mentioned composite powder 4 is then successively charged from a powder supplying device 6 to the formed molten pool 9 to form the hardened layer 10 simultaneously with the above-mentioned heating. The uniform hardened layer 10 is formed on the surface of the Al alloy casting 5 in this way and the wear resistance thereof is improved.

IPC: F03B13/18
Filed: 1981-03-30
Abstract: PURPOSE:To convert wave energy into potential energy of water, bylifting water through utilization of wave energy as dynamic energy for a pump driving machine. CONSTITUTION:A plunger 6 has a buoyancy since its inside is hollow. A rotatable hinge 4 is normally supported above the water surface by the resultant buoyancy of links 1, 2. An air-filled cushion member 11, fixed to a quay wall 12 in a half-buried manner, serves as a means for protecting the hinge portion 4 from damages when it collides onto the quay wall 12. Here, provided that lateral waves advance toward the quay wall 12 from the offing, the link 1 receives the motion of waves on its flat surface and prevents the motion of waves, so that the links 1, 2 are turned respectively clockwise and counterclockwise around the hinge 4 until they extend in a straight line above a fixed link 3. Resultantly, the plunger 6 is pushed upwared by the link 2.

Abstract: PURPOSE:To easily and accurately confirm the assembling accuracy of a mirror at the time of its assembling. CONSTITUTION:The light beam outputted by a laser oscillator 18 as a light beam generating means fixed so as to penetrate the center of the optical axis of a projection lens 12 in parallel to the optical axis is reflected by a green transmission dichroic mirror 11 and changed in direction by 90 deg. to irradiates a position P1 on a fitting plate 15. At this time, a position confirmation hole 16 matches the irradiated position P1 as long as the green transmission dichroic mirror 1 is correctly fitted, but if the position confirmation hole 16 and irradiated position P1 shift from each other as shown in a figure, the fitting angle, position, etc., of the green transmission dichroic mirror 11 are adjusted so that the position confirmation hole 16 and irradiated position P1 match each other. Similarly, the light beam reflected by a reflecting mirror 10 irradiates a position P2 on the fitting plate 15, so the position of the reflecting mirror 10 is adjusted to align the position confirmation hole 17 and irradiated position P2 with each other. Consequently, the adjustment positions of the mirror fitting positions are easily and accurately confirmed.
