Filed: 1992-03-31
Abstract: PURPOSE:To generate the plasma easy to start an electric discharge, having good homogeneity over a large area during the discharge, and optimum for each process in multiple kinds of processes. CONSTITUTION:A microwave guide window 12 having an aperture 9 with a variable opening level is provided between a wave guide 6 introducing microwaves and a vacuum tank 3 generating plasma 17.

Title: Piston ring material made of steel
Inventor: HOSOO HIROSHI
IPC: C22C38/00
Filed: 1988-04-30
Abstract: PURPOSE:To improve seizure resistance and wear resistance as a piston ring material by specifying C content in a steel and also regulating respective contents of other chemical components. CONSTITUTION:A piston ring material made of steel has a composition consisting of 0.9-1.4% C and the balance essentially Fe and the seizure resistance of this steel is regulated to a value equivalent to that of cast iron. By incorporating 0.1-10.0%, in total, of one or more elements among Cr, Mo, and V into the above steel, self-wear resistance can be improved without causing deterioration in seizure resistance. By this method, the use of this piston ring material for a piston ring for internal combustion engine is made possible while obviating the necessity of surface treatment, such as hard chrome plating.

Title: Positive type electron beam resist composition
Inventor: MIYAGAWA MASASHI
IPC: G03F7/039
Filed: 1983-06-17
Abstract: PURPOSE:To obtain a positive type electron beam resist high in resistance to ion etching by replacing the hydroxyl groups of an alkali-soluble resin having them in the molecular structure. CONSTITUTION:The hydroxyl groups of a resin having them in the molecular structure, such as phenol novolak resin, cresol novolak resin, or polyvinylphenol are replaced by alkyl sulfonate or aromatic sulfonate groups to give an alkali- insoluble resin. When said resin is irradiated with electron beams, the sulfonate groups are cut off and made soluble in alkali. A positive type electron beam resist is thus obtained. A substrate is coated with said resist, exposed, and developed to form a pattern, and when it is subjected to ion etching by using gaseous CF4, said resist is strong in resistance to the ion etching.

Title: Device for applying flux
Inventor: IWASA SANDAI
IPC: B05C3/18
Filed: 1992-03-31
Abstract: PURPOSE:To apply extremely low residue flux and to improve the soldering quality by setting the capacity of a flux pool formed on the outside of a flux nozzle remarkably smaller as compared with that of a flux vessel. CONSTITUTION:The sum total S+S of the distance S between the outside of the flux nozzle 3 and an inner wall of the flux vessel 2 is set equally to or less than the sum total B+B of the length B in the carrying direction of a substrate at the bottom 3a of the flux nozzle 3. The capacity of the flux pool 18 formed on the outside of the flux nozzle 3 is set remarkably smaller as compared with that of the flux vessel 2. In other words, the sum total S+S of the length S of the flux pool 18 is set remarkably smaller than the length L=S+S+B+B in the carrying direction of the substrate of the flux vessel 2. Consequently, only new flux in a state close to virgin flux is always applied on the substrate.

Filed: 1989-04-27
Abstract: PURPOSE:To obtain the reflecting mirror having excellent moisture resistance and mass productivity by forming a silica gel film which has a single crystalline network structure and is uniform and dense without having pinholes as a protec tive film. CONSTITUTION:An underlying film 2 formed by vacuum deposition of, for example, SiO, having a good adhesive property to both of a substrate 1 consisting of plastics and a light reflecting film 3 is formed on the substrate and the light reflecting film 3 is formed thereon. This light reflecting film 3 is oxidized to lose the light reflecting characteristic by reacting with the moisture in the air, etc., in an exposed state and, therefore, the protective film 4 is constituted of the silica gel film thereon. Since this silica gel film is obtd. by the polymn. of the silica gel applied on the surface of the light reflecting film 3, the film has the dense network structure which is intrinsically single crystalline or monolithic and dense without having pinholes. The nearly perfect shut off of the external moisture is thus possible. The reflecting mirror having the excellent moisture resistance and mass productivity is obtd. in this way.

Abstract: PROBLEM TO BE SOLVED: To obtain a sound-source estimation device whose noise-resistant performance is excellent and in which a computing amount is small, and to provide its recording medium. SOLUTION: In a method, sound signals received by a plurality of microphones are processed so as to estimate the position of a sound source.

Then, regarding the cross-correlation function, a time difference which gives the maximum value of the cross-correlation function between a reference microphone and another microphone is found. The time difference is used as a preliminary estimated time difference. A time difference which makes the power of a delay sum maximum regarding all the microphones is searched near the preliminary estimated time difference. The time difference is used as an estimated time difference. Lastly, the position of the sound source is computed on the basis of the estimated time difference.
