Title: Method of connecting linear gas bearing
Inventor: MIYATA EIJI
IPC: F16C32/06
Filed: 1988-08-22
Abstract: PURPOSE:To prevent a gas from being generated from a connecting surface, when a plurality of linear gas bearings used in a vacuum are to be connected, by providing a stepped part to the outer part of the bearing at a mating face of each linear gas bearing and filling this stepped part with a sealant after each linear gas bearing is connected, thereby improving flatness and parallelism of the outer surface of the bearing. CONSTITUTION:A stepped part A is provided to an end surface of each connecting surface of housings 2 and 3, which constitute a plurality of linear gas bearings. After the housing 2 and the housing 3 are connected, the outer surface is machined to the predetermined accuracy. After this machining work, this stepped part A is filled with a sealant 8. Owing to this sealant 8 used for filling, the gas is prevented from being generated from the connecting surface, thereby enabling this bearing to be used in a vacuum. With this contrivance, since the outer surface can be machined after the housings are connected, flatness and parallelism of the outer surface of the bearing can be improved.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/64
Filed: 1987-08-20
Abstract: PURPOSE:To obtain a high-density magnetic recording medium which has improved C/N and durability at a wide band range by providing specific granular projections onto a magnetic recording layer having a thin ferromagnetic metallic film on a coated layer of ferromagnetic metallic powder. CONSTITUTION:The magnetic recording layer formed with the thin ferromagnetic metallic film 3 on the coated layer 3 of the ferromagnetic metallic powder has 1-10K/mu<2> granular projections. For example, a monomer of styrene is introduced into a polyethylene terephthalate film which has 8mum thickness and is used as a substrate and while glow discharge polymn. is executed, Fe is evaporated by a resistance heating method to fix fine Fe particles of 300Angstrom  in average to the coated layer in the state of dispersing the particles in said layer by which the 2mum coated layer 2 is formed. The conditions are so selected as to form the granular projections to 3.7K/(mum)<2> in average and to 140Angstrom  height of the granular projection by adjusting the amt. of argon with respect to the amt. of the monomer at this time. The friction with a magnetic head at the time of high speed sliding is thereby greatly decreased and the durability of the thin ferromagnetic metallic film is improved; in addition, the C/N at short wavelength is improved. The C/N at long wavelength is improved since the ferromagnetic metallic powder contributes additionally to the increase of output.

Title: Solid-state image pickup device
Inventor: WATARI TAKASHI
IPC: H04N5/369
Filed: 1994-08-31
Abstract: PURPOSE:To increase the dynamic range of a solid-state image pickup device to the incident light by controlling electrically the charge amount that is stored in response to the exposure value. CONSTITUTION:A CCD is controlled so that its storable charge amount is changed to a 1st charge amount (Qsat1not equal to 0) and then to a 2nd charge amount (Qsat2not equal to 0, Qsat1<Qsat2) within a single image pickup period. Then the incident light quantity-electric signal relation having the knee characteristic (bend of characteristic graph) is corrected into a proportional relation by the correction of gains. Thus a range where the incident light can be be uniquely shown in a stored charge amount is increased. As a result, the dynamic range of a solid state image pickup device can be increased with use of a CCD equal to a conventional one.

Title: Vapor-phase synthesis of diamond thin film
Inventor: SHIBATA NORIYOSHI
IPC: C30B29/04
Filed: 1990-08-04
Abstract: PURPOSE:To obtain the title higher-purity diamond thin film on a specified substrate under mild conditions, i.e. at relatively low temperatures, by adding a halogen element to the decomposition reaction system for feedstock. CONSTITUTION:For example, a reaction vessel 1 is fed with hydrogen gas, methane gas and chlorine gas each at a specified flow speed through feed pipes 2a, 2b and 2c, respectively. The reaction vessel is then vacuumed to a specified level, and concurrently, a silicon substrate 5 is heated to about 600 deg.C using microwave and maintained at this temperature. During this period, the substrate 5 is irradiated with ultraviolet rays S from a high-pressure mercury lamp 9, thus giving the objective diamond thin film M on the substrate 5. With the present method, the halogen element added to the reaction system is decomposed and highly active halogen radicals are formed; thereby the feedstock gas having carbon element will be decomposed at a higher rate even if the temperature of the substrate is lower than those in conventional cases; thus, the objective good-quality diamond thin film can be obtained at substrate temperatures as low as 600 deg.C.

IPC: F04D29/32
Filed: 1981-12-23
Abstract: PURPOSE:To improve the rigidity of the rotor by a method wherein the low- pressure side of the rotor is made by laminating a plurality of stages of wheel disks and the high-pressure side thereof is made by arranging moving blades along the circumferential direction thereof to form an integral hollow cylindrical rotor while both parts of the rotor are connected by bolts. CONSTITUTION:In the moving blades for the rotor of the compressor, the size of the moving blade 11a on the low-pressure side of the rotor is large but the same of the moving blade 11b on the high-pressure side of the rotor is small. In case the chord size c of the moving blade is large, it is more profitable in the strength thereof to make axial blade groove along the width thereof and the blade 11 is planted onto a wheel 12. The moving blade 11b is planted onto the rotor 15 along the circumferential direction thereof and the rotor is formed to the hollow cylindrical rotor since the smaller moving blades occupy a majority of stages in the whole body of the compressor, while the end of the high-pressure stage is connected to the wheel 12 of the low-pressure stage through stacking bolts 12. According to this method, the outer diameter of the rotor 15 becomes to the diameter of ridigity, therefore, the rigidity of the whole body of the rotor is increased and the rotational vibration thereof may be stabilized.
