Abstract: PURPOSE: To provide an ozone generating method and device therefor capable of drastically reducing a Cr compd. in the generated ozone even if a stainless steel pipe is used as the generated ozone delivery pipeline. CONSTITUTION: The ozonizer 7 is provided with the ozone generating cell 9 having a raw gas supply part 8, a high voltage impressing means 16 and an ozone discharge port 10 and the lines 11 and 12 for delivering the generated ozone. A gas prepared by adding carbon dioxide and/or carbon monoxide 2 to oxygen 1 by 10-20 vol.% is used as the raw gas. The ozone thus produced is appropriately used to form a metal oxide, especially silicon oxide.

Abstract: PURPOSE:To provide a solvent deodorizing method of a dry-cleaning apparatus which enables the elimination of odor of a petroleum base solvent by a simple method and effectively. CONSTITUTION:A petroleum base solvent in a solvent storage tank 2 is drawn with a circulation pump 5 to be supplied to a washing tank 8 through a filter (cartridge filter tank 6) and an adsorbent (carbon tank 7) and circulated to the solvent storage tank 2 through a button trap 3 from the washing tank 8. In a dry-cleaning apparatus of such a type, an ozone gas is injected into a solvent as fine bubble circulating through the dry-cleaning apparatus. Then, odor components of the solvent itself and malodorous components of pollutants accumulated in the solvent are decomposed by ozone for deodorizing them.

Abstract: PURPOSE:To provide a long durable electric discharge reaction device with stable performance which is free electrode wear resulting from high density electric discharge and contamination of a reaction product by a harmful substance as well as is capable of generating a high concentration of ozone. CONSTITUTION:The electric discharge reaction device is composed of a dielectric present between a high voltage electrode 3 and a grounded electrode 4 to generate a silent discharge and/or a creeping discharge between the dielectric 2 and the high voltage electrode 3, and/or between the dielectric 2 and the ground electrode 4. Thus the substance is allowed to undergo a reaction in a discharge space 1. A metal material which is highly corrosion-resistant against the substance in the discharge space 1 and a reaction product there and also can be used for anodic oxidation coating, is used as an electrode material in a part which comes in contact with an electric discharge in the discharge space 1. The part which comes in contact with the electric discharge in the discharge space 1 is coated by an anodic oxidation treated film. In addition, a highly pure or pure, significantly corrosion-resistant and chemically stable substance film is formed tightly on said anodic oxidation treated film within said applicable range.

Abstract: PURPOSE:To provide a ceramic dynamic pressure bearing and grooving method for it by which the quantity of fine particulates generated in the machining face of a fluid dynamic pressure generating groove can be reduced or eliminated and the machining of the ceramic material after the formation of the fluid dynamic pressure generating groove can be eliminated. CONSTITUTION:A dynamic pressure generating groove 2 is formed by radiating YAG pulse laser beams on the sliding face 1a of a bearing base body 1 made of ceramics of Sic, Si3N4, and Al2O3. On the internal surface of this dynamic pressure generating groove 2, a refined layer 2a comprising ceramics, which is the base metal of the ceramic bearing base substrate 1, melted and solidified is formed.

Abstract: PURPOSE:To contrive the improvement of durability of a liner prevented in its corner part from forming a clearance as small as possible by previously forming the liner integrally with its bottom and vertical wall parts and adapting the fellow ceramics to each other from both directions in the corner part formed between the bottom and vertical wall parts. CONSTITUTION:A channel-shaped liner 20, whose internal side surface is protected being coated with ceramics 21, is connected to each blade plate 2 of an impeller. The liner 20 is a structure previously forming its bottom wall part 22 and right and left side wall parts 23, 24 as an integral unit, and the liner 20 connects to its internal side surface the ceramics 21. The liner 20, in its right and left corner parts, forms a structure such that an end face of a ceramics 21b, connected to the internal side surface of the bottom wall part 22, is adapted to a surface of ceramics 21a connected to the internal side surface of the left side wall part 23, while an end face of ceramics 21c, connected to the internal side surface of the right side wall part 24, is adapted to a surface of the ceramics 21b.

Abstract: PURPOSE:To continuously and promptly cool a plurality of containers, by arranging a continuous transfer means and a cool air-blowing-out means for containers and by feeding a plurality of containers from a charging opening of a freezer and discharging required numbers of the containers from another discharging opening. CONSTITUTION:Respective jugs J placed on a conveyor C from a charging opening 1 are transferred continuously by the guide of respective guide walls G and cooled effectively by blowing of cool air due to respective fans 21 on the way. When the first jug J reaches the end of the path, it abuts against the stopper 22 by a holding lever 24 and stops. When the corresponding button to required numbers of jugs is pushed, a solenoid 25 is energized and a hook 24b of the holding lever 24 relieves the connection of a pin on the lower face of the stopper 22 and the first jug J reaches the discharging opening 2, pushing a discharging door 1. The solenoid 25 is relieved by a sensor detecting the revolved angle of the stopper 22 after its proceeding by an angle corresponding to required numbers of jugs J and the holding hook 24b returns to the preventing position of revolutions of the stopper.

Abstract: PURPOSE:To make stop and release smooth and reliable in a gate mechanism of a conveyor or the like by disposing a stopper plate made of a disk with its outer circumference formed with arcuate recesses of a radius smaller than the radius of a cylindrical body on a base plate capable of advancing and retracting elastically relative to a travel path and controlling it by means of an external signal. CONSTITUTION:A hook 7a of a restraint lever 7 engages with a bolt head portion 6of a stopper plate 3 projecting by a maximum limit from an opening Ga of a guide wall G into a travel path to make the stopper plate 3 immovable. A cylindrical vessel B transported by a conveyor C comes into contact with an end 3a of an arcuate portion 3b of the stopper plate 3 and stops. When a solenoid 12 is urged by a control signal to retract the restraint lever 7 and release the bolt 6, the stopper plate 3 is rotated by the conveyor C and by the vessel B being urged forward so that the vessels B are passed through in succession. This arrangement makes the stop and release smooth and reliable.
