Title: Production of ceramic film
Inventor: KOBAYASHI TOSHIO
IPC: C03C17/25
Filed: 1989-03-30
Abstract: PURPOSE:To obtain a ceramic film preventing cracks, capable of accurately controlling a composition ratio by coating a substrate with a coating solution comprising a compound containing constituent elements of ceramics, oxidizing organic components of the coating film by plasma and calcining. CONSTITUTION:A compound containing constituent elements of ceramics is dissolved or dispersed into a solvent to give a coating solution, which is applied to a substrate, organic components of the coating film are oxidized by plasma, removed and the coating film is calcined to give the aimed ceramic film. Removal of the organic components by plasma oxidation in the above-mentioned production of ceramic film is caused by reaction between O2<+>, O<+>, O<->, e<->, ultraviolet light, etc., and organic components in the coating solution and oxidation of the organic components. By the oxidation, the reaction is advanced from the surface of the coating film exposed to the plasma atmosphere and cracks are prevented to produce a ceramic film of the aimed composition. Since energy of plasma oxidation is insufficient to sublimate a metal, composition control of ceramic film is accurately carried out.

Title: Photodetector
Inventor: MOCHIZUKI CHIORI
IPC: H04N5/369
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To achieve both satisfactory shielding and a satisfactory aperture rate, by providing a shielding layer that shields a switch TFT and further has an aperture region the area of which is larger than the light receiving area of a photoelectric conversion element. SOLUTION: A SiN film is formed as a passivation film 33 by plasma CVD, and then a red filter is formed as a shielding film 28 in a specified pattern. Polyimide resin is simultaneously placed as a protective film 29 in a specified pattern, and unnecessary parts, such as wire lead-out sections, are etched by RIE using the polyimide resin as a mask. It allows a switch TFT to be sufficiently shielded to use for the shielding member a material that selectively blocks the wavelength of incident light or a wavelength to which the switch TFT is sensitive, as mentioned above. This makes it possible to place a shielding layer having an aperture region the area of which is larger than the light receiving area of a photoelectric conversion element. Thus, it is possible to obtain a photodetector with reduced TFT leakage current and cross talk.

IPC: C30B15/02
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for pulling up a crystal, capable of reducing the danger of clogging in a replenishing pipe as much as possible and preventing a fine granular fraction from entering a pulling chamber above a liquid level. SOLUTION: This crystal pulling apparatus for producing a crystal block is equipped with a replenishing pipe 7. Granular silicon 17 is sent through the replenishing pipe to a crucible 2 filled with molten silicon 3 arranged in the interior of a container 1. The replenishing pipe 7 is furnished with a ring-shaped chamber 20 between an inner wall 18 and an outer wall 19. The ring-shaped chamber is opened at the end face of the lower part of the replenishing pipe 7 and is connected to a protective gas source 13 for supplying a protective gas. The temperature of the inner wall face of the replenishing pipe is lowered by the ring-shaped chamber of the replenishing pipe and the gas flowing in the replenishing pipe in comparison with a case of a conventional well-known replenishing pipe. Consequently, the danger of seizing of a replenishing material is avoided.  Simultaneously, a gas curtain is formed around the outlet of the replenishing pipe by circulating a gas to the ring-shaped chamber and the gas curtain prevents the replenishing material from entering the pulling chamber.

Abstract: PURPOSE:To obtain a thin film magnetic head with high efficiency, by providing a pair of coils which magnetize upper cores divided by a gap respectively, and using the upper cores formed vertically to a sliding plane as the main magnetic pole of a vertical head. CONSTITUTION:A core with thickness of L formed vertically to the sliding plane that is a part of the upper cores 5a bi-sected by a magnetic gap plane 6 is used as a main magnetic pole head, and when perpendicular recording is performed, magnetization is performed so that the same polarity can be attached on the upper end of the upper core 5b used as the main magnetic pole and the magnetic pole generated on the gap end face of the upper core 5a on one side. When an in-plane medium is used, the current direction of the pair of coils is controlled so that polarity different from each other are attached on those magnetic poles by a current control part 10. At the time of reproduction, it is controlled so that reproducing signals with the same polarity can be induced on the pair of coils similarly as in a conventional ring type head. In such a way, it is possible to generate the main magnetic pole head with high recording efficiency, and also, to record and reproduce both the in-plane medium and a vertical medium, and to simplify the constitution of a device.
