Title: Coil for superconducting magnet and manufacture thereof
Inventor: UMEYA KAORU
IPC: H01F6/06
Filed: 1987-12-08
Abstract: PURPOSE:To improve the efficiency of a superconducting magnet coil, by laminating superconducting thin films of ceramic quality or intermetallic compound quality in multiple stages as a spiral structure, and electically connecting the films. CONSTITUTION:Spiral grooves are formed on one surface or both surfaces of a hollow disk shaped substrate 1 made of metal plastics or ceramics. Superconductive material made of ceramic quality or intermetallic compound quality is evaporated in the spiral grooves. A superconductor thin film coil 2 is formed in a spiral shape from an outer terminal point (b) of the disk to an inner terminal point (a). Thus a superconductor board is formed. Said superconductor boards are laminated through insulating films in multiple stages. The spiral coils at all stages are electrically connected in series or in parallel. Thus the superconductive magnet coil having excellent coil efficiency can be formed.

Title: Eliminator for spray type humidifier
Inventor: NABESHIMA YASUSHI
IPC: F24F6/14
Filed: 1994-11-18
Abstract: PURPOSE: To keep water drops from flying even with a higher air velocity by housing two filter media formed of a fiber material into a frame body so that a space part is produced between the filter media. CONSTITUTION: In an eliminator, filter media 1 and 1 formed by compressing a fiber material like a woven cloth are mounted being spaced by a frame body 2 so as to produce a space part 3 between the filter media 1 and 1. Two single eliminators each thus obtained are bound successively in two levels, upper and lower, to be set within an air conditioning equipment. During the operating of the air conditioning equipment, when a mist sprayed from a humidifier C passes through the first and second filter media 1 and 1 of the eliminators on an air flow, the filter media 1 and 1 trap moisture which is not absorbed by the air. Fine water sprayed is condensed into water drops when hitting the first filter medium 1.  With the repetition of such a condensing operation, the water drops grown to a fixed size descends through the fiber of the filter media 1 and 1 by the dead load despite an air pressure and are drained outside the apparatus with a drain pipe 5.

IPC: F23L17/04
Filed: 1993-12-10
Abstract: PURPOSE:To prevent an air amount from being lowered owing to pressure loss that is increased as an exhaust tube length is increased in a combustor with a heat exchanger of a variable exhaust tube length by providing a drawing part with a variable cross section in the exhaust tube, and increasing the cross sectional area of the drawing part correspondingly to an increase of the exhaust length. CONSTITUTION:In a petroleum FF(forced feeding) heater, combustion air from fresh air passes through an air supply tube 2 from a feeding top outside passage 1, and is pressurized by a fan 3 and is fed to a mixing chamber 4. Coal oil is supplied from an oil feeding pump to the mixing chamber 4, and an evaporated fuel is mixed with the combustion air into premixed gas which is then sent to a flame hole 5 in a burner for its combustion. In such a combustor, a drawing part a51 with a variable cross section is provided in an exhaust tube 9, which is expanded in its diameter as the exhaust tube length is increased. Hereby, the flame is located downstream of the antinode, and the antinode of a pressure is located upstream when the exhaust tube length is increased. Thus, vibratory combustion is prevented.

Title: Mold for addition polymer silicone gel
Inventor: MATSUMOTO KOKI
IPC: C08L15/02
Filed: 1996-11-06
Abstract: PROBLEM TO BE SOLVED: To easily release a silicone gel molding by adopting a rubber mold of a predetermined shape containing a specific % of free sulfur. SOLUTION: A silicone gel mold 5 has, for example, a cylindrical molding part 51, which has a molding surface 52. Free sulfur of a contact surface 53 in contact with silicone gel molding 6 (or silicone composition of material for manufacturing the gel) is 0.01 to 0.1%. When the sulfur is less than 0.01%, a silicone oil layer 7 is scarcely formed, and there is a fear of hard release from a mold 5. Meanwhile, when it exceeds 0.1%, the layer 7 becomes excessively thick, and hence there is a fear of forming no silicone gel molding 6 of a predetermined shape.
