Title: Optical information reproducing device
Inventor: MATSUDA IKUO
IPC: G11B7/135
Filed: 1981-01-14
Abstract: PURPOSE:To shorten the overall height and overall length of an optical system by disposing a laser light source part, a beam splitter, and a signal detection part linearly, and by disposing a light focusing part and a reflecting mirror at right angle to said direction. CONSTITUTION:A laser beam 11 emitted from a left light source part 24 is supplied to a beam splitter 14, where a constant portion of it is reflected downward and then reflected by a mirror 29 to travel upward. A constant portion of the laser beam reincident to the beam splitter 14 is transmitted there and focused through a condenser to strike a disk signal surface 17. The laser beam reflected by the disk signal surface 17 is made incident to the beam splitter 14 as a return beam. A constant portion of the return beam is reflected by the beam splitter to strike a signal detection part 25 placed at the laterally opposite side to the light source part 24.

Abstract: PURPOSE: To improve the metal recovery rate from used large-size iron and steel products by bringing a liquefied gas into contact with the large-size iron and steel products subjected to crushing to cool these iron and steel products down to the embrittlement temp. area of ferrous metals and pulverizing the cooled large-size iron and steel products, then refining and recovering iron and copper therefrom. CONSTITUTION: The liquefied gas is brought into contact with the large-size iron and steel products contg. the copper based metals to precool these iron and steel products in a precooling and crushing device 1; thereafter, the iron and steel products are crushed by a hammer mill or press crushing machine and the crushed steel products are transferred to a cooler 2. The liquefied gas is brought into contact with the crushed large-size iron and steel products to completely cool the products down to the embrittlement temp. of the ferrous metals in this cooler 2. The cooled large-size iron and steel products are pulverized by a low-temp. pulverizing machine 3. The pulverized scrap is treated with an insulating oil, etc., by a high heat treatment in a reforming device 4.  The scrap is thereafter classified to magnetic materials and nonmagnetic materials by magnetic sepn in a recovering device 5. These materials are transported to a stage for recovering the copper based metals. The magnetic materials are efficiently recovered as iron scrap. The treatment costs are thus reduced.

Title: Optical fiber communication system
Inventor: AOKI TAKAHIRO
IPC: H01S3/0941
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To furthermore extend the span length of a very long span communication system for sending excitation light from both transmitting and receiving ends to an optical fiber amplifier on an optical fiber transmission line.

Title: Cleaning method of semiconductor substrate
Inventor: MATSUO CHIZUKO
IPC: H01L21/304
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To successfully remove both metal impurity and fine particles adhered to a substrate surface. SOLUTION: After a semiconductor substrate 11 is washed with a mixed liquid 15 in pH of 2 to 6 mixed with an organic acid and fluoric acid, the substrate is washed with an oxide liquid. When the contaminated substrate 11 is soaked with the mixed liquid, the naturally oxidized film 12 at the substrate surface is removed by the fluoric acid and fine particles 13 on the film and metal impurity 14 and metal impurity in the film transfer into the liquid as shown or Fig. (b). Since the mixed liquid 13 acid solution in the pH of 2 to 6, fine particle is charged to negative like the substrate surface and the metal impurity ion in the liquid becomes negative complex ion due to the complexing effect of the organic acid.  As a result, since the fine particle and metal impurity become negative at the surface potential like the surface potential of the substrate, adhesion or re-adhesion to the substrate can be prevented as shown on Fig. (c). When this substrate is soaked into the oxidizing liquid, a hydrophilic oxide film is formed at the substrate surface by the oxidizing liquid, and organic acid and organic substance adhered to the substrate surface can be decomposed and eliminated without complexing of metal impurity.

Title: Hologram recording material
Inventor: IKEGAMI YOSHIZUMI
IPC: G03F7/00
Filed: 1982-01-18
Abstract: PURPOSE:To obtain a photosensitive material sensitive to long wavelength light, and improved in sensitivity, resistance to moisture coupled with heat, and light resistance, by using a combination of a cyclic cis-alpha-dicarbonyl compd. and dyes for a polymer having vinylcarbazole rings. CONSTITUTION:A hologram recording material contains polymer having vinylcarbazole rings, a cyclic cis-alpha-dicarbonyl compd. producing radicals on light irradiation, and dyes as a light sensitizer or a spectral sensitizer. The carbonyl radicals generated by irradiation of light draws off hydrogen from the 3- or 6- position of the carbazole ring in exposed areas, and cross-links said ring to increase mol.wt. and consequently, presumably refractive index, as well as solvent resistance. The unexposed parts are swelled by treatment with a solvent, and becomes a half-dissolved state, and then it forms a relief pattern, presumably due to contraction action of a nonsolvent.

Filed: 1984-01-17
Abstract: PURPOSE:To enable the relative parallelism of a reflection mirror with an output mirror to be maintained with good accuracy by a method wherein a laser tube is covered with an outer cylinder of mirror form in outer surface, and cooling air is made to pass between the outer cylinder and the laser tube. CONSTITUTION:The outer cylinder 9 has blowing holes 10 and exhaust holes 11 provided at the positions opposed to those of the holes 10 in part of the outer periphery, forms a mirror surface in the outer plane, and is so installed as to cover the laser tube 2. Besides, the blowing hole 10 side is provided with a blower 12 to supply cooling air to the gap between the laser tube 2 and the outer cylinder 9 via blowing holes 10. According to the cooling method of such a construction, the laser tube 2 can be cooled directly and uniformly by the action of thermal diffusion of the cooling air supplied from the blower 12, and by the action of radiated heat reflection due to the fact that the outside of the outer cylinder 9 is a mirror plane, leading no generating of distorsion caused by the difference in temperature. Therefore, the relative parallelism of the reflection mirror 1 with the output mirror 3 can be maintained with good accuracy.
