Title: Manufacture of photoconductive film
Inventor: NISHIGAKI SATOSHI
IPC: H01L31/0248
Filed: 1985-02-18
Abstract: PURPOSE:To enable the fine working of electrodes by flattening steps caused by formation of the titled film, by a method wherein a groove equivalent to the thickness of this film is previously formed on top of a substrate, in the manufacture of a photoconductive film formed out of a single substance of a II-VI group compound semiconductor containing Cd or a compound semiconductor containing these. CONSTITUTION:A photoconductive paste is applied over a substrate 1 to the same thickness as the depth of a groove 2, thus eliminating steps caused by the thickness of a photoconductive film 3. This film 3 successively undergoes calcination in an N2 atmosphere and does not additionally generate steps which comes to problem during the later electrode processing. The substrate 1 thus flattened by formation of a photoconductor thick film is coated with Ti, Mo, Cr, Ni, Au, or the alloy made of at least two or more kinds from among these metals, which is then processed into a required fine electrode pattern 4 by using a normal photolithography technique or lift-off technique, resulting in the production of a photoelectric conversion element.

Title: Liquid crystal display element
Inventor: HADO HITOSHI
IPC: G02F1/1337
Filed: 1988-02-15
Abstract: PURPOSE:To prevent the generation of an orientation defective line and to expand a visual field angle by forming a liquid crystal composite of a liquid crystal display element of a double refractive index control type by a spiral structure. CONSTITUTION:A liquid crystal composite 20 of a liquid crystal display element 18 of a double refractive index control type is allowed to have a spiral structure, and brought to very small pre-tilt array in which a major axis of a liquid crystal molecule 22 is about 0.5 deg. against the surface of substrates 12, 13. In such a way, a fact of having a pre-tilt angle for prescribing a tilt molecule of a liquid crystal in some prescribed direction at the time of applying a voltage has an effect for preventing the generation of an orientation defective line. Therefore, when the liquid crystal molecule is silted by applying a voltage, not only the tilt but also a twisted molecular orientation are taken, and accordingly, the optical quality becomes constant irrespective a visual angle, and the visual field angle expands.

Title: Wind pressure sensitive type windmill blade
Inventor: SATO HIDEKI
IPC: F03D7/04
Filed: 1993-01-06
Abstract: PURPOSE:To enable each windmill blade to cope with abrupt change in wind pressure without making its structure complex by providing each spring so that the pitch angle of each blade is changed in response to change in wind pressure applied to each blade. CONSTITUTION:Each blade 1 is rotatably supported by a boss 2. When the blade 1 is tried to be rotated by wind pressure F, a link 3 is pulled out, so that a spring 5 is thereby held down via a crosshead 4. The spring 5 is deformed in response to wind pressure F, and subsequently the pitch angle of the blade 1 is changed in accordance with the aforesaid deformation. The change of the pitch angle of each blade 1 permits not only the efficiency of the windmill to be improved but also air resistance to which each blade is subjected at the time of a sudden gust of wind, to be lowered while its projected area is made small, so that the windmill can thereby keep rotating without being damaged.

Title: Formation of coated film on material to be coated
Inventor: MUKOGASA KOICHI
IPC: B22C3/00
Filed: 1987-02-16
Abstract: PURPOSE:To permit easy sticking of a coated film forming material on a material to be coated and to improve the quality of the coated film stuck and formed thereon by previously coating a surfactant on the surface of a core, master mold, etc., to be used for casting, then coating the coated film forming agent thereon. CONSTITUTION:A soap soln. is used as the surfactant. After said soln. is coated on the surface of the core by spraying or brushing, etc., the soap soln. coated on the core surface is dried as a 2nd stage. A mold coating material is then coated on the coated and dried core surface by a spraying, brushing, dipping or showering method, etc., as a 3rd stage, by which the coating stage is completed. Then, the adhesive power of the mold coating material to the core surface is improved by the soap soln. and, therefore, the generation of uneven coating of the mold coating material is decreased. Since the soap soln. layer is merely interposed between the core surface and the mold coating material layer, the amt. of the surfactant to be used is decreased as compared to the case of mixing the surfactant with the mold coating material and coating the mixture on the core surface.

Title: Formation of thin film of oxide superconductor
Inventor: KAMITO KOJI
IPC: C30B29/22
Filed: 1989-02-10
Abstract: PURPOSE:To increase the efficiency of film formation of applying DC voltage on a stabilized zirconia substrate when noble metal films are adhered to both sides of the substrate and thin films of an oxide superconductor are formed on the surfaces of the noble metal films in an oxygen atmosphere under reduced pressure. CONSTITUTION:Films of a noble metal such as Pt are adhered to both sides of a stabilized zirconia substrate. This substrate is set in a sputtering device so that the noble metal films as anodes confront targets. The vapor growth device is evacuated while feeding oxygen into the device. When DC voltage is applied between electrodes, oxygen in a formed atmosphere is taken in by load. This oxygen penetrates the substrate in the thickness direction by ionic conduction and deposits on the surfaces of the anodes. At the same time, thin film of an oxide superconductor are formed on the surfaces of the anodes by vapor growth. The deposited oxygen permeates the thin films and reacts to supply the deficiency of oxygen during film formation. The amt. of oxygen in the resulting thin films can be made proper.
