Title: Highly efficient flue-smoke tube boiler with superheater at part of smoke tube block
Inventor: SHIODA AKIO
IPC: F22B7/12
Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To enable saving of water and a fuel by a method wherein a part of a smoke tube block is separated from a water chamber part, enclosed by a container to form a superheater to which water of the water chamber part is guided and turned to steam to harness, assuring the same effect obtained by continuous blowing so as to keep high temperature water from being discarded outside. SOLUTION: Water heated from a lower water chamber 3 of a flue/smoke tube boiler is sent to a heater 4. A superheater 4 made up of a smoke tube block is heated by high temperature combustion gas heat from a combustion chamber 1 and the water sent from the lower water chamber 3 is heated into steam to be delivered to a steam section 5. The water in the superheater 4 increases in concentration and the operation of the boiler is ended. When the boiler is stopped or during the operation thereof, the water in the superheater 4 alone is subjected to blowing to be replaced with the water of the water chamber part. The water discarded by the blowing can be turned to steam to harness.  This eliminates the need for discarding the water of the water chamber part and thus, the water discarded by blowing is confined to the water of the part of the superheater 4 thereby enabling saving of water and a fuel.

Water is accumulated in the main body 2 when the impeller 7 is rotated, and resistance to the impeller is generated. However, since a closable cover 3 is provided, the cover is opened by an opening and closing means 11 as the pressure (weight) in the main body 2 increases in proportion to the magnitude of pressure, hence the water is discharged, the inside of the main body 2 is kept at the same pressure at all times, and the resistance value exerted on the impeller 7 by the water is kept constant. Further, the cover 3 is opened when the pressure in the main body 2 is increased and the water is discharged, and consequently foreign matter such as a material to be coated does not intrude from the outside.

Title: Coating method for repairing surface of film
Inventor: SHIMIZU TOYOICHI
IPC: B05D1/28
Filed: 1988-10-05
Abstract: PURPOSE:To simply repair the flaw part of a film by a method wherein a solid coating material capable of forming a film fixed to a sheet having specific surface tension in a lumpy state in a releasable manner pressed and transferred to the minute recessed part formed to the surface of the film by removing a minute film flaw part and cured.

IPC: F04B39/16
Filed: 1987-10-07
Abstract: PURPOSE:To prevent compressor elements from breakage and motor elements from seizure in a gas-liquid separator of an enclosed rotary compressor by disposing a partition plate having specially arranged orifices above an introducing pipe connected to compressor elements. CONSTITUTION:Refrigerant introduced from an expanded pipe 26 of a gas-liquid separator 28 provided on the outside of an enclosed container is compressed by compression elements 4 through a partition plate 24 and an introducing pipe 25 to be discharged from a discharge pipe 13 to a condenser. Since the partition plate 24 has orifices 24a which reduce the diameter and are disposed more coarce as they approach the center, copper and iron powder in the refrigerant are prevented from direct intrusion into the introducing pipe 25. Also, since the orifices 24a enlarge the diameter and are disposed denser as they approach the outside of partition plate, the refrigerant can pass through the outside orifices 24a even if the inside orifices 24a are choked. Also, even if copper and iron powder intrudes from the outside orifices 24, the powder is precipitated on the bottom of gas-liquid separator 28 without intruding directly into the introducing pipe 25 so that compression elements 4 are prevented from breakage while the partition plate 24 is prevented from loading so that motor elements 1 are prevented from seizure.
