Title: Optical disk improved in reflectivity
Inventor: TSUKADA HARUMICHI
IPC: G11B7/2539
Filed: 1987-02-03
Abstract: PURPOSE:To obtain a DRAW type optical disk having reproduction interchangeability with a reproduction-only optical disk which can be read with a reproduction-only player for CDs and VDs as well by interposing a thin transparent film layer having the refractive index lower than the refractive index of a plastic substrate between said substrate and recording film. CONSTITUTION:A thin film 3 of MgF2 having 1.45 refractive index is formed by a vacuum deposition method on the polycarbonate substrate 1 which is formed by injection molding and has 130mm diameter, 1.2mm thickness and 1.59 refractive index. The recording film 2 of Te/Se having 95:5 atom.% ratio is then formed to about 400Angstrom thickness thereon. Prescribed values of reflectivity % and C/N dB are obtd. by changing the film thickness Angstrom  of MgF2 to, for example, 500, 750, 1,000. The recording signal subjected to signal processing so as to be made into the same information signal as the information signal of a CD is written on such DRAW type optical disk by using a recorder having a feed mechanism resembling to the reed mechanism for laser cutting. The DRAW type disk subjected to the writing can be reproduced by a commercially marketed CD player.

Title: Erector for steel segment
Inventor: SHIRASAWA TAKAO
IPC: E21D11/40
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To eliminate the need to attach or detach a pin, and to easily grip and open a steel segment by pressing the hanging piece of a steel segment by a gripping tool consisting of a fixing part and movable part. SOLUTION: As a gripping part 3 of an erector, a slide shaft 7 of a gripping part 3b on the movable side is loosely fitted into the slide cylinder of a gripping part 3 on the fixing side and a guide hole 8a of a guide 8, and the piston of a hydraulic jack 4 is screwed to the slide shaft 7, thus allowing the gripping part 3b on the movable side to freely approach and separate from the gripping part 3a on the fixing side. As another scheme, the gripping part 3b on the movable side may be rotated around a support.  Then, irregularity 3c is formed on a gripping surface for gripping the hanging piece of a steel segment as a slip prevention, and an engagement groove 5 is formed for fitting the engagement plate of the hanging piece, thus eliminating the need to insert a pin by forming a hole in the hanging piece when the hanging piece is gripped by the gripping part 3, and hence easily gripping and releasing the steel segment.

Title: Sputtering target
Inventor: KANEDA YASUSHI
IPC: C23C14/34
Filed: 1989-01-31
Abstract: PURPOSE:To reduce fluctuations in leakage magnetic field even if erosion proceeds and to stabilize sputtering by constituting a target of a ferromagnetic substance in which magnetic permeability is distributed in a sheet thickness direction so that magnetic permeability is reduced from the rear toward the surface. CONSTITUTION:A magnetron sputtering target material is constituted of a ferromagnetic substance, and, while regulating the composition of this target to a fixed composition in a sheet thickness direction, magnetic permeability is regulated so that it is reduced from the rear toward the surface. In order to produce the above target, heating conditions in the surface and rear of the target are usually modified. By this method, the concentration of leakage magnetic field on an eroded part can be reduced because magnetic permeability is low at the target surface and increases toward the rear even if erosion proceeds when erosion is locally brought about in the sputter surface of the target. Accordingly, use efficiency can be improved, and also fluctuations in sputtering conditions can be reduced.

Title: Heat-developable color photosensitive material
Inventor: AOZUKA YASUO
IPC: G03C1/047
Filed: 1992-01-13
Abstract: PURPOSE:To obtain the heat-developable color photosensitive material high in image density (Dmax) and low in fog density (Dmin) and cost by incorporating a constant amount of calcium in accordance with the total amount of a binder. CONSTITUTION:The heat-developable color photosensitive material comprising at least photosensitive silver halide, a dye donor, and a binder on a support, incorporates further calcium in an amount of, at least >=5000ppm of the total amount of binder. If it is too much, clouding or precipitation becomes liable to occur in the coating solution to be used at the time of manufacturing the photosensitive material resulting in deterioration of filtrability of the coating solution. When the film of the photosensitive material is continuously processed, water absorbing capacity changes and fluctuation of photographic performance is made liable to occur by this raction, thus permitting polymers advantageous in cost to be used without limit and reduced in cost by adjusting the amount of calcium.

Title: Picture reader
Inventor: KITAHARA FUMIHIRO
IPC: H04N1/04
Filed: 1997-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a picture by means of automatic starting read, particularly near a maximum read position in an auxiliary scanning direction, having no difference of a picture characteristic by a read area. SOLUTION: Slow-up curve is selected at a motor start (S1) and a motor is started. Normally, a system is started from regular curve. Then, an intermittent operation and a read position are always checked to a read end (S5). The start and the stop of the motor being the driving source of a read mode for reading the original in a line unit from a main scanning direction, moving the line read position in the auxiliary scanning direction and executing read and of a driving mechanism for moving the position are controlled while slow-up/slow down are executed. Thus, the deterioration of the picture by automatic starting read can be prevented by control for executing the intermittent operation during read and executing read at slow-up/down near the maximum read position in the auxiliary scanning direction.

Abstract: PURPOSE:To allow to grow an epitaxial layer with a uniform impurity concentration without resulting in abnormal growing, by ion-implanting the same impurities as those in the epitaxial growth layer before the epitaxial growing. CONSTITUTION:On a semiconductor substrate 1, a buried diffusion layer 2 of the different conductive type from that of a layer intended to epitaxial-grow and a buried diffusion layer 3 of the same conductive type as that of the layer intended to epitaxial-grow are formed. To form an ion-implanted impurity layer, the same impurities as those in the layer intended to epitaxial-grow are ion-implanted and the ion-implanted layer is annealed. At this time, the surface portion 8 of the buried diffusion layer 2 is compensated by the ion-implanted layer 7. Next, the ion-implanted layer 7 is removed and the epitaxial growing results in an epitaxial grown layer 5 with a uniform concentration. In this way, the same impurities as those in the layer 5 intended to epitaxial-grow are ion-implanted so that the ion implantation depth is below the thickness of the layer to be vapor- etched, preventing auto-doping at the epitaxial growing from resulting.

Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To improve safety by preventing a low-temperature burn that may be caused by an error of a sue method of a user in the case of an electric blanket sable as both covering and underlying ones, and rapidly set the inside of a bed at a comfortable temperature when no person is present in the bed at the time of turning on power.
