Abstract: PURPOSE:To prevent surfaces of a liner from wearing in its corner part by forming an irregular surface in the surfaces of ceramics along a flow direction of gas in the corner part formed by a bottom wall part of the liner and its side wall part. CONSTITUTION:A channel-shaped liner 20, protected and coated in its internal side surface with ceramics 21, is connected to each blade plate 2 of an impeller. Surfaces of ceramics 21a, 21b in right and left corner parts 25, 26 of the liner 20 are irregularly formed along its lengthwise direction. Consequently, the corner part 25 is prevented from generating a smooth flow of gas, weakening simultaneously even flow energy of dust, and the liner 20 is prevented from easily generating wear in its surface by the dust.

Abstract: PURPOSE:To enhance dynamic pressure generating groove forming accuracy by coating a base material of a dynamic pressure bearing made of ceramics with resin or oil capable of absorbing a YAGQ switch pulse laser beam, radiating the YAGQ laser beam so as to form a recess portion formed into a predetermined shape, and removing the residual coating film. CONSTITUTION:A coating film 14 made of resin or oil, e.g. dimethyl silicone oil colored into blue capable of efficiently absorbing a YAGQ switch pulse laser beam is formed on a base material 10 of a dynamic pressure bearing made of ceramics. The YAGQ switch pulse laser beam is radiated onto the base material 10 made of ceramics along a trace 11 so that a recess portion 15 such as dynamic pressure generating groove or the like of a slide bearing is formed on the base material 10. After forming the recess portion 15, the residual coating film 14 is removed.

Abstract: PROBLEM TO BE SOLVED: To provide an ozone generator of a discharge system which uses high-purity gaseous oxygen to obviate the degradation in the ozone concn. in gaseous ozone as a raw material. SOLUTION: The ozone generator of the discharge system for generating the gaseous ozone by the discharge in discharge cells by using the high-purity gaseous oxygen as the gaseous raw material is provided with an ozone concn. meter 6 for detecting the ozone concn. of the gaseous ozone passing a gaseous ozone discharge tube 5. The output of the ozone concn. meter 6 is fed back to a control section 3 which maintains the ozone concn. of the gaseous ozone at a prescribed value. Subsequent one unit among the several discharge cells 1-1 to 1-6 is stopped for the prescribed time until the ozone concn. is restored and the ozone is generated by the remaining discharge cells.

Abstract: PROBLEM TO BE SOLVED: To efficiently wash Japanese clothes and silk products in whole at a low cost by adding silicone soap to a petroleum solvent at the time of washing in the dry cleaning method using the petroleum solvent as a washing liquid and adding ozone gas to it to wash the laundry. SOLUTION: The laundry is inserted into a washing tub 8, a petroleum solvent is fed to the washing tub 8 from a solvent storage tank 2 and circulated by a circulating pump 5 to wash the laundry, an air diffusing pipe 11 is arranged at the bottom section of a button trap 3, and ozone gas is mixed into the solvent. Silicone soap (detergent) is fed into the washing tub 8 from a soap feeding means 18. The soap in the solvent is adsorbed to the laundry, its concentration in the solvent is decreased as the quantity of the laundry is increased, and the soap quantity is controlled in sequence to maintain the prescribed concentration. The output of an electric conductivity sensor 12 is monitored by a control means 17, and the soap feeding means 18 is controlled to maintain the electric conductivity in the solvent at the prescribed value during the washing of the laundry.

Abstract: PURPOSE:To maintain a cargo loading surface in a same plane and make a curvature radius of direction change smaller by attaching a rhombus plate at each pitch and on a link outer surface of one side of a single row chain with the longitudinal direction of the rhombus perpendicular to the chain center line and with its outer side surface constituting a common surface. CONSTITUTION:A roller chain is constituted with a pair of parallel links 1a, 1b and a roller 1c. On the outside of the link la of the roller chain 1, an elongated rhombus-shaped plate 2 made of plastic material or the like is attached with its longitudinal direction directed perpendicular to the center line of the chain 1 and with all the outer surfaces of the plates 2 located in a common plane. When a conveyor chain C constituted in this way makes a directio change of a transfer path, the chain can be bent as far as the angle theta formed by the tapered edges of adjacent plates 2 becomes zero and both edges come in contact with each other to make a curvature radius smaller. At the same time, a cargo loading surface can be maintained in a common plane.
