Title: Method for synthesizing diamond
Inventor: KATSUMATA SATOSHI
IPC: C23C16/26
Filed: 1990-08-27
Abstract: PURPOSE:To synthesize diamond at high speed while obviating the necessity of using carbon monoxide harmful to human body as gaseous raw material by subjecting a gaseous raw material consisting of carbon dioxide and hydrogen to reduction treatment, bringing this gas into contact with a base material, and synthesizing diamond on the base material. CONSTITUTION:Carbon dioxide and hydrogen are used as gaseous raw material, and this gaseous raw material is subjected to reduction treatment. Subsequently, this reduced gaseous raw material is excited and brought into contact with a base material, by which diamond is synthesized on the base material. It is desirable that the above gaseous raw material is previously purified to such an extent that it does not adversely affect the quality of diamond. The mixing ratio of the components in the gaseous raw material is properly selected according to the reduction treatment method and the desired composition of gas after the reduction treatment. It is preferable to use, as the above reduction treatment method, various plasma treatments, particularly microwave plasma treatment, from the standpoints of efficiency (yield), reaction time (treatment time), and the simplicity of equipment.

IPC: G03G21/00
Filed: 1989-08-31
Abstract: PURPOSE:To prevent a lump of toner which is formed at the time of cleaning from sticking and to obtain excellent image quality by setting each press- contacting part of a cleaning blade and a cleaning roller at a specific angle to the horizontal line. CONSTITUTION:The roller 13B of a cleaning device 13 removes completely a small amount of toner which is left between the surface of a photosensitive body belt 1 and a cleaning blade 13A and easy to form a lump when the blade 13A leaves the belt 1 after the cleaning. In this case, each press-contacting part of the cleaning blade and the cleaning roller is set at -30 deg. <= theta1 <= 60 deg. and 30 deg. <= theta2 <= 90 deg., where theta1 is the angle between the horizontal line passing the center of rotation of a rotary roller 3 and the press-contacting position of the blade 13A, theta2 is the angle between the horizontal line passing the center of rotation of the roller 3 and the press-contacting position of the roller 3. Consequently, toner which is scraped off with the blade 13A slides down on the back surface of the blade and no toner is accumulated nearby the front end of the blade.

Abstract: PURPOSE:To facilitate an improvement in the uniformity of a single crystal and the formation thereof in a large area, by using a three-layer composite film as an electron- absorbing film in a method of manufacturing a semiconductor device wherein the single crystal is formed by energy beams. CONSTITUTION:An amorphous or polycrystalline silicon film 3 to be single-crystallized is formed on the surface of an insulating film 2 on a substrate 1, and an insulating film 4 is formed on the surface of the film 3. Then, a three-layer composite film 8 composed of an electron-absorbing belt-shaped high-melting metal film 7, a polycrystalline silicon film 5 for relaxing a thermal stress acting between the metal film 7 and the insulating film 4 and a metal film 6 being easier to deform at high temperature than the high-melting metal and the polycrystalline silicon is formed on the surface of the insulating film 4. When electron beams are applied to this electron-beam-absorbing film 8, the thermal stress generated due to a difference in a thermal expansion coefficient between the high-melting metal film 7 and the polycrystalline silicon film 5 is relaxed and reduced by the metal film which is deformed easily. Thereby the generation of a local thermal stress in the single- crystallized film 3 is reduced, the uniformity of a single crystal thus formed is improved, and also the area thereof is easily enlarged.

IPC: B05B1/02
Filed: 1986-09-24
Abstract: PURPOSE:To enhance washing effect and blood circulation promoting effect by extending the stay time of fine air bubbles in a bathtub, by providing an air bubble forming plate constituted by forming a specific three-layered structure into a semispherical shape at the opening part of a nozzle housing on the blowoff side thereof. CONSTITUTION:An air bubble forming plate 21 is constituted by a method wherein a pressure reducing body 14 for finely dividing air is held between a pressure reducing plate 13 having pores 16 having a pore size of 1mm or less formed to the almost entire surface thereof and a dispersing plate 19 having emitting holes 17 larger than the pores 16 and the whole is formed into a semispherical shape. This air bubble forming late 21 is mounted to a predetermined opening part so that the dispersing plate 19 turns to the outside. Since fine air bubbles formed by the pressure reducing plate 13 and the pressure reducing body 14 can be radially dispersed in a bathtub 1 by the dispersing plate 19, the fine air bubbles blown in the bathtub 1 becomes low in apparent concn. with respect to hot water and prevented from unification. As a result, the stay time of the fine air bubbles in the bathtub is extended.

IPC: C07B61/00
Filed: 1992-08-25
Abstract: PURPOSE:To safely and efficiently obtain carbonates in high selectivity and high activity by reacting carbon monoxide with an alcohol and a hydrogen acceptor in the presence of a metallic complex. CONSTITUTION:Carbon monoxide is made to react with an alcohol (e.g. methanol) and a hydrogen acceptor (e.g. an aldehyde, a ketone or an acetal) in the presence of a complex of a group 5 to 10 metal of the periodic table [e.g. Cr(CO)6 or further pyridine as a ligand] at 30-350 deg.C to afford the objective carbonates. The objective substance can be obtained by removing oxygen from the interior of the reactional system and the deterioration in selectivity due to the carbon monoxide by the formation of water as a by-product while avoiding the danger of explosion without using a highly toxic substance having the possibility of causing environmental problems. The carbonates are useful as a polymer such as a urethane or a polycarbonate, a raw material and synthetic intermediate for medicines and agricultural chemicals and as an alkylating agent for a raw material for producing ethers or tetraalkylammonium salts, a gasoline additive, a solvent, etc.

Abstract: PURPOSE:To uniformize magnetic flux density in a gap between magnetic poles by forming a vertical section of a coil setup to the orbital direction of a charged particle beam as specified, in case of a deflecting magnet at a synchrotron radiation generator or the like. CONSTITUTION:A pair of opposed cryostats 6, having a superconducting coil of a deflecting magnet built in, are set up in a void in a cold core 1, and upper superconducting coils 2a, 2b and lower superconducting coils 2a', 2b' are installed symmetrically with respect to an orbital surface of a charged particle beam 5. In addition, a vertical space h2 of these coils 2a, 2b at the outer circumferential side of an orbit of the beam 5 is made larger than a vertical space h1 of the coils 2a, 2b at the inner circumferential side, while the horizontal width of a return yoke 7b at the outer circumferential side is made larger than that of a return yoke 7a at the inner circumferential side and as for the sectional form, the inner circumferential side and the outer circumferential side are formed asymmetrical separately. With this setup, magnetic resistance in magnetic flux passing through both inner and outer circumferential sides is uniformized over the whole orbit length of the charged particle beam rather than a position where the charged particle beam passes through whereby magnetic flux density in a gap between magnetic poles becomes uniformized.
