Title: Magnetic material
Inventor: TAJIMA SHIN
IPC: H01F1/33
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To produce a soft magnetic material having superior magnetic property, mechanical strength and corrosion resistance at a low cost by forming a three-dimensional network of insulating layers, made of electrically insulating dispersed particles each having particles of a diameter smaller than a matrix particle on the interface between matrix phases made from the matrix particles of highly saturated magnetized material. SOLUTION: A matrix phase is formed with matrix particles of saturated magnetized material in one process. Dispersed particles are prepared with insulating powder, each having a micro small particle diameter in the other process. The matrix particles and the dispersed particles are mixed at a prescribed formulation percentage, and put into a pot to be stirred and mixed in a ball mill. A product is then obtained, in which insulating fine particles made of the dispersed particles are adhered to magnetic iron powder granulated particles of the matrix particles. The product is molded into a desired shape, and the matrix particles are then made into matrix phase by burning the product under inert atmosphere, or vacuum. Insulating phases are formed with insulating fine particles in the shape of a three-dimensional network on interfaces between the matrix phases.

Abstract: PROBLEM TO BE SOLVED: To made light distribution characteristics uniform in the periphery with a lamp axis being a center without a metal base being bent and fixed with respect to the lamp axis by fixing the metal base at an engagement with a base engagement insert part formed in the same diameter as an inner diameter of a skirt part. SOLUTION: A mount side of a metal base 2 of a cover part 1 has a base engagement insert part 11 at which a skirt part 21 of an E26 type metal base 2 is engaged and mounted in the outer periphery and a cylindrical part 12 with the same diameter as an inner diameter of a shell 22 of the metal base 2. Fixation of the metal base 2 is engaged with the base engagement insert part 11 with the substantially same diameter as the inner diameter of the skirt part 21, the metal base 2 is neither bent nor fixed with respect to a lamp axis in which respective contact faces are parallel to each other, and concentric light distribution characteristics can be obtained when the base 1 is mounted to a socket and is lit.  Further, since the base engagement insert part 11 and the cylindrical part 12 sides on which the base 2 of the cover part 1 is mounted is straight free of a screw groove, molding is easy. Since the base 2 is engaged at a site opposite to the skirt part 21 of the base, connection becomes secure and rigid.

IPC: G03F7/26
Filed: 1991-04-12
Abstract: PURPOSE:To apply a flat resist film having a uniform thickness to the surface of a substrate having a step part and improve the dimensional accuracy of a resist pattern by a method wherein the step part is filled with HMDS.

Title: Granular powder high-pressure transport method
Inventor: NAKA KOUSON
IPC: B65G53/16
Filed: 1981-05-25
Abstract: PURPOSE:To prevent abrasion of the inner surface of a transport pipe and crushing of granular powder by blocking a discharge opening when a tank contains a predetermined very little amount of granular powder in transporting granules such as ore in the tank by pressurized air. CONSTITUTION:A predetermined quantity of granular powder 10 is poured into a blow tank 1, and the interior of the tank 10 is pressurized to be a set pressure P1 through a pressure alarm device 8 from a valve 19. The, valves 12, 21 are opened to supply the granular powder 10 together with pressurized air through a discharge opening 11, a pipe 15, the valve 12 and a pipe 13 to a hopper 14. When the granular powder 10 in the tank 1 comes to a predetermined very little amount, powder flow resistance in the pipe 13 decreases remarkably so that the pressure in the tank 1 drops below steady pressure P2. Such dropped pressure is detected by the pressure alarm device 8, and the valve 12 is blocked by the detecting signal to stop discharging the granular powder 10, which can prevent abrasion of the inner surface of a transport pipe and crushing of the granular powder 10.

Title: Method for detecting liquid leak
Inventor: MURAYAMA YASUHIRO
IPC: G01M3/20
Filed: 1994-04-19
Abstract: PURPOSE:To enable a liquid leak to be detected easily by applying both a heating compound which generates heat when reacted with the leaked liquid and a dye compound which discolors when absorbing heat to a subject for measurement. CONSTITUTION:A liquid 7 leaking from a tank 1 generates heat when reacted with a heating compound contained in the applied paint, and a dye compound is discolored by absorbing this heat. A monitoring camera 4 photographs the tank 1, a pipeline 2, and the floor face 3 either constantly or intermittently, and photographic data are processed by an image processing means 5, and when the means 5 detects any color change, an alarm means 6 sounds an alarm to warn of the liquid leak. The liquid leak from the tank 1 can thus be detected easily and quick measures can be taken. The use of the dye compound that is irreversibly discolored enables the position of the liquid leak to be determined easily even after the liquid leak has stopped.
