Title: Position detection device
Inventor: ISHIZAKI AKIRA
IPC: G01D5/245
Filed: 1993-01-19
Abstract: PURPOSE:To provide a position detection device which has simple structure and provide practically sufficient accuracy by using a rotor exclusively with an integral number of pieces of salient poles which are equal to the sum or the difference of the number of pair poles of an exciting winding and an output winding and without a winding. CONSTITUTION:In a stator 11, slots 11a are formed at equal intervals over the whole of the inner circumference in which the exciting windings of the number p1 of pair poles and the output windings of the number p2 of pair poles are placed. The rotor 10 does not have any winding but has a salient pole 10a of iron core formed in the outer circumference. The number p1, p2 of pair poles an the number of a salient poles 10a i.e., the number N are so selected that the relation of p1+p2=N or p1-p2=+ or -N is satisfied. When the exciting winding is for single phase and the output phase is for two-phase or three-phase, the two-phase or three-phase voltage of a sinewave having the movement of 1/N of the entire circumference of the rotor 10 is induced into the output winding. When the exciting winding is for two-phase, the output voltage becomes a sinewave which is changed by 2pi in phase when the rotor 10 is moved by 1/N. Thereby, a position can be detected.

Title: Diffusion furnace device
Inventor: FUJISAWA MASATO
IPC: H01L21/22
Filed: 1986-01-17
Abstract: PURPOSE:To conduct precise thermal diffusion treatment by constituting an silica trough at the same curvature as an silica tube and washing a foreign matter adhering on the silica trough. CONSTITUTION:With an silica trough 20, a section takes an arcuate shape at the same curvature as an silica tube 3, length is longer than an silica boat 5, and it is formed by quartz. The boat 5 on which wafers 6 are formed in line in an orderly way is housed in the silica tube 3 under the state in which the boat is placed on the silica trough 20. Consequently, the boat 5 is put on the silica trough 20, and a lower section in the silica tube 3 is brought to the state in which the lower section is covered with the silica trough 20, thus resulting in an adhesion on the surface of the silica trough 20 of reaction flakes generated through thermal diffusion treatment. Since thermal diffusion treatment is executed continuously, the boat 5 is inserted into the silica tube 3 by an auto-loader, etc., but only the silica trough 20 is brought into contact with the silica boat 5, thus resulting in an adhesion on the silica trough 20 of foreign matters generated by friction. Accordingly, when only the contiminated silica trough 20 is washed, the degree of washing in the silica tube 3 is ensured, thus resulting in precise thermal diffusion treatment.

Abstract: PURPOSE:To make it possible to measure the distribution of the intensity of strain in a compound semiconductor substrate and an epitaxial film at high resolution, by observing a photoluminescence topography using first exciting light, and dividing and measuring backward scattering light caused by second exciting light. CONSTITUTION:A first exciting laser light beam 20 having energy larger than the band gap of a sample 13 is projected on the specified region on the surface of the sample 13, which is a compound semiconductor crystal, approximately uniformly from an Argon laser 9. A photoluminescence topography in the specified region is observed. A second exciting laser light beam 30 is projected in a minute region in a specified region from a laser 8. The backward scattering light is guided into a double-diffraction grating spectroscope 3 through an objective lens 12 and a mirror 15. The light undergoes spectroscopic action and is amplified by means of an amplifier 5. Thereafter, the light is recorded by means of a recorder 6 as the intensity of strain. Then the second exciting light 30 is swept in the specified region, and the intensity in each minute region is obtained. Thus the distribution of the intensity of the strain in the specified region is measured.

Title: Electro-optical device
Inventor: SUZUKI TERUYA
IPC: G02F1/133
Filed: 1990-01-16
Abstract: PURPOSE:To improve the yield of production by changing a signal electrode potential level or a scanning electrode potential level to restore a defective picture element like software operation. CONSTITUTION:A voltage waveform to be impressed to a point short-circuit defective picture element is changed to restore the defective picture element like software operation. In the case of driving a normal picture element other than a defective one, charge is injected to the normal picture element through a non-linear resistor element at the time of using a selected waveform and the picture element is turned on and off by utilizing holding characteristic based upon the capacity of liquid crystal. On the other hand, the defective picture element is driven and turned on and off by an effective voltage impressed to the liquid crystal. Consequently, the electro-optical device can be manufactured with high yield without increasing the number of production processes.

Abstract: PURPOSE: To set different compression conditions between the inside and outside of a specified area that a user can optionally set. CONSTITUTION: The user specifies a part which is given importance of picture quality as the area through an area input means 12. An area dividing means 14 divides inputted image information into blocks of 8×8 pixels and outputs them in order to a compressing means 16.

Title: Optical information recording medium
Inventor: KANNO TOSHIYUKI
IPC: G11B7/246
Filed: 1986-01-17
Abstract: PURPOSE:To obtain a pollution-free optical information recording medium which has high reflectivity and recording sensitivity, permits stable writing and reproduction of an optical signal and has high stability to light and humidity by forming a recording layer contg. a specific org. dye. CONSTITUTION:The recording layer contg. one of the org. dyes expressed by 15 kinds of similar prescribed constitutional formulas such as formulas I and II is formed. The recording layer is obtd. by dissolving the dye into an ethyl acetate, toluene and other solvent and forming a thin film on a substrate by a spinner method and other methods. The recording sensitivity is higher as the thickness of the thin film is smaller but the reflectivity depends on the film thickness and therefore, the thickness is preferably 10-1,000nm, more preferably 30-500nm. The film formability, heat resistance and moisture resistance are improved by adding a binder resin to 1-40wt%, more preferably 3-20wt% to the dye.

Title: Mold for continuous casting
Inventor: MIYATO MOTOHISA
IPC: B22D11/059
Filed: 1987-01-16
Abstract: PURPOSE:To improve the heat resistance and wear resistance of an inner face of mold for continuous casting and to lengthen the service life of mold by forming in order alloy plating layer composing of nickel and phosphorus, cobalt plating layer and chromium plating layer on the inner face of mold constituting by copper or copper alloy. CONSTITUTION:On the inner face of mold constituting by copper or copper alloy, the alloy plating layer composing of nickel and phosphorus is arranged, and on this layer, the cobalt plating layer having >=0.3mum thickness is arranged and further on the layer, the chromium plating layer is arranged. As the second layer of plating layer of cobalt, which is the metal forming the solid solution with both metals of nickel and chromium, is included between the nickel and phosphorus alloy plating layer as the first layer and chromium plating layer as the third layer, the adhesion each between the layers is remarkably improved. A reason, which the chromium plating layer is arranged on the most outer surface, is that its melting point, such as 1,890 deg.C, is higher than the melting point of alloy plating of nickel and phosphorus, such as 890 deg.C, and molten steel is difficult to stick to it.
