Patent JP-H05234756-A (JP)
Title: Electronic part
Inventor: MURATSU MICHIO
IPC: H01F27/29
Filed: 1992-02-20
Abstract: PURPOSE:To prevent generation of lead discontinuity caused by resin crack of an electronic part wherein a lead is molded with resin. CONSTITUTION:After mold release is applied to a surface of a lead 2 which is wound around a core 1, a resin 3 is molded. Thereby, the lead 2 and the mold resin 3 are made independent through the existence of the mold release. Even if crack A is generated in the resin 3 in a heat shock test, tensile force does not work on the lead 2 and discontinuity of the lead 2 caused by crack generation can be completely prevented.

Title: Manufacture of electrode for molten carbonate fuel cell
Inventor: NIRASAWA HITOSHI
IPC: H01M8/14
Filed: 1989-03-25
Abstract: PURPOSE:To retard decrease in pores to stabilize performance for a long time by adding a dispersion of oxide or fine particles of metal different from a base metal to the base metal particles of a gas diffusion electrode and by sintering the mixture to form a porous sinter for an electrode. CONSTITUTION:Oxide fine powder is added to an organic solvent such as alcohol to prepare a dispersion. The dispersion is added to metal powder which is a base material of an electrode. The preferable content of the dispersion is 0.5-5wt% because less content decreases creeping resistance based on the dispersion of the oxide fine powder and excess content causes low mechanical strength caused by decrease in sinterability of the base metal. They are put into a mechanical mixer together with mixing hard balls, and mixed for 10-100 hours depending on the kind of material and dispersed condition. The raw powder obtained is molded in a specified shape and the molding is sintered in a reducing atmosphere such as hydrogen atmosphere to obtain a porous sinter. Stress applied during operation and creep caused by heat are retarded.

Title: Drilling machine
Inventor: SAKATA FUMIAKI
IPC: E21B7/18
Filed: 1995-03-30
Abstract: PURPOSE: To prevent underground water pressure from entering a casing by providing a check valve at the end of the casing, opening a valve member when drilling the ground, and closing the valve member when stopping the drilling operation, as when extending the casing. CONSTITUTION: When a casing 11 is rotated and thrust into the ground, a feedwater pipe 14 is slightly pushed out, and a valve main body 19 moves in the direction of an end. Next, the valve member 19b of the main body 19 separates from and releases the seat 23a of a gate 23 formed inside the outer pipe of a check valve device 16. Then excavated earth and sand converted into muddy water is allowed to enter the casing 11, and is discharged out of a muddy-water takeout pipe at the end. When the drilling operation is stopped, the pipe 14 is drawn in, the main body 19 is moved by a spring 24, and the valve 19b abuts to the seat section 23a to close the gate 23 so as to stop the earth and sand from entering the casing 11. Therefore when the casing is extended during a drilling operation under high pressure, gravel can be prevented from splashing out of the casing ahead.

Title: Rotor of permanent magnet type rotary machine
Inventor: MIZUNO TAKAYUKI
IPC: H02K15/03
Filed: 1995-03-30
Abstract: PURPOSE: To provide the rotor of a permanent magnet type rotary machine where centrifugal force is improved without reducing electrical characteristics. CONSTITUTION: A groove 23 for main magnet and a groove 22 for supplementary magnet are provided by securing connection parts A and B at a core 21 and a main magnet 26 and a supplementary magnet 25 are engaged to the grooves 23 and 22. The main magnetic flux of each pole can be obtained by the main magnet 26 and the connection parts A and B can be magnetically saturated by the leakage magnetic flux of the supplementary magnet 25, thus preventing magnetic flux from leaking via the connection parts A and B. Then, since the core is connected in one piece by the connection parts A and B and has a high centrifugal force, no other reinforcing members are required, thus reducing an air gap, enhancing magnetic flux density, and preventing an effective core length from decreasing.

Abstract: PURPOSE:To prevent the scattering matter, vapor, etc. scattered by the irradiation of laser beam from depositing on the inside surface of the light transmitting member of a vacuum vessel by irradiating the laser beam to a rotatable body after injecting a gas into the vacuum vessel. CONSTITUTION:A rotatable body 2 is rotated by a rotating and driving mechanism and a vacuum pump 4 is operated to evacuate and suck the inside of a vacuum vessel 1. When the number of revolutions of the rotatable body 2 arrives at a dangerous number of revolutions, the vibrations of the rotatable body 2 are detected and measured by using a vibration detector 5, and from the results thereof, the unbalance quantity of the rotatable body 2 is detected by an electronic computer 6, and the working rate necessary for eliminating this unbalance is determined. Next, the number of revolutions of the rotatable body 2 is lowered down to a workable speed, and a gas is injected by opening the stop valve 12 of a gas injection tube 11. The laser beam from a laser oscillator 10 is irradiated to the prescribed position on the surface of the rotatable body 2, so that part of the surface is melted and scattered. Thereby, the diffusion of the scattering matter and vapor is prevented by the inert gas, and their pickup on the inside surface of the light transmitting member is prevented.
