摘要:
A method of and system for cleansing a toilet or urinal are proposed which require less maintenance work and are safer to users than conventional methods using acid substances, and which can prevent the formation of stain on the toilet or urinal effectively and suppress the generation of ammonia sufficiently, thus accomplishing a sufficient countermeasure to the stench. A urinal (A1) is provided with a continuous electrolytic cell (1) having at least a pair of electrodes, a passage formed between the electrodes, and an inlet and an outlet that lead to the passage. Tap water is electrolyzed by the continuous electrolytic cell (1), whereby free chlorine is produced. Then the water containing free chlorine produced is supplied to the urinal (A1), and the water containing free chlorine sterilizes the inside of the urinal, thus preventing urease, an enzyme carried by bacteria, from acting to decompose urea. By this method, the deposition of uric stone and the generation of the stain and stench are suppressed on the surface of the urinal and in the trap of the urinal.

A composite structure forming method comprises the steps of first pre-treating brittle material fine particles to impart an internal strain to the brittle material fine particles, secondly causing the brittle material fine particles in which the internal strain has been created to collide with a substrate surface at high speed or applying a mechanical impact force to the brittle material fine particles containing the internal strain therein provided on the substrate surface, to deform or fracture the brittle material fine particles, re-joining the fine particles through active new surfaces generated by the deformation or fracture, forming an anchor section made of polycrystalline brittle material of which part bites into the substrate surface at a boundary section between the new surfaces and the substrate, and further forming a structure made of polycrystalline brittle material on the anchor section.

A composite structure forming apparatus adapted to ejecting and causing an aerosol generated by scattering brittle material fine particles in a gas to collide with a substrate at high speed to form a structure made of the brittle material. The apparatus includes an aerosol generator for generating the aerosol, a nozzle for ejecting the aerosol, a shredder for shredding the brittle particles cohering in the aerosol and preventing cohesion of the brittle material fine particles, and a classifier for classifying the brittle material fine particles in the aerosol. The apparatus also includes a pretreatment device for creating internal strain in the brittle material fine particles, and a position control device for controlling the position of the nozzle relative to the substrate. The apparatus further includes a container having a sieve and a vibration device, and one or more of these components may be associated with the aerosol generator.

Object: To provide a machineable glass ceramic which has excellent machineable properties and various other physical property values.Solution: A machineable glass ceramic comprises a glass matrix having substantially only fluorine phlogopite crystals dispersed therein, wherein an average dimension in the directions of major axes of said fluorine phlogopite crystals is less than 5 μm. The machineable glass ceramic constituted as above is produced by forming and degreasing glassy powder containing at least Si, Al, Mg, K, F and O, and thereafter by sintering the same at temperatures of 1000-1100 degrees centigrade.

摘要:
In order to control and reduce generation of disjoined grains from a plasma-resistant member, the present invention provides a plasma-resistant member having no pores and boundary layers. In a layer structure made of yttria polycrystal and formed on a surface of a member for a semiconductor manufacturing apparatus on a side exposed to plasma, the ratio of pores to the surface of the layer structure is less than 0.1 area %. With this, corrosion from pores never progresses even in a plasma atmosphere. It is also possible to control and reduce disjoined grains due to such corrosion.

In order to control and reduce generation of disjoined grains from a plasma-resistant member, the present invention provides a plasma-resistant member having no pores and boundary layers. In a layer structure made of yttria polycrystal and formed on a surface of a member for a semiconductor manufacturing apparatus on a side exposed to plasma, substantially no hyaline boundary layer exists in the yttria polycrystal. With this, corrosion from a boundary layer never progresses even in a plasma atmosphere. It is also possible to control and reduce disjoined grains due to such corrosion.
