IPC: H01P1/20
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To obtain a dielectric filter with a structure by which a wrong direction stuck label can simply and properly be prevented. SOLUTION: The basic configuration of this dielectric filter is also similar to that of a conventional dielectric filter.

Furthermore, the label 9 is stuck to the major side of the metallic case 7 in a way of covering the solder release hole 2.  A mortise 8 that is open is formed to a corner of the major side of the metallic case 7 and the label 9 is stuck onto the major side of the metallic case 7 in an asymmetrical way to cover other parts of the major side of the metallic case 7 than the mortise 8.

Inventor: SAKAMOTO KAZUO
IPC: C22C1/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining a forging molding by forging in only one step; wherein the light metal alloy under a semi-molten condition coexisting the solid/liquid phases with a solid phase ratio of a specific value or less or under a molten condition at the temperature right above the melting point, is injection molded so as to improve the moldability of the injection molding member of the light metal alloy. SOLUTION: For manufacturing the material for plastic working light metal alloy, a source tip is inserted into a hopper 6, forwarded in a cylinder 1 by a screw 2, heated by a heater 5, and injected to a die 4 with a high frequency injection mechanism 3. After the mold release, the preformed material is taken out, and is taken out again after forging to be a forged material. At that time, after the light metal alloy is made under the semi-molten condition of 20% or less solid phase ratio coexisting the solid/liquid phases or the molten condition at the temperature right above the melting point, it is injection molded. Furthermore, the material being plastic worked is heat treated. The average grain size of the liquid phase is 300 μm or less under the semi-molten condition. The temperature for forging is 400 deg.C or less.  The light metal alloy contains Mg as a base metal and 4-9.5 wt.% Al as an alloy component.

Title: Rotary fluid pressure cylinder
Inventor: OTA KOJIRO
IPC: B23B31/30
Filed: 1989-10-11
Abstract: PURPOSE:To concentrically rotate a supplying body and a rotary valve without the influence of the change of the pressure of pressurized fluid by a concentric action means having at least one of a fluid restirctor and a circular groove which change the difference of flow quantity, to the difference of pressures, due to the inclination of a circular gap. CONSTITUTION:When a rotary valve 5 is concentric to a sleeve 14, there is no inclination in the flow, in a circular gap 30, of pressurized oil supplied from an oil passage 25b', a fluid restirctor 25d via an oiling port 24 to an oil passage 25, a pressure gradient in circumferential and axial directions are identical to each other along the full circumference of the circular gap 30 of about several tens microns. A suppling body consisting of a sleeve body 13, a sleeve 14, etc., is apt to offset to a rotary valve 5 due to the dead weight thereof and thereby the upper portion of the circular gap 30 becomes narrower than the lower portion, pressure in the vicinity of the upper portion of the fluid restirctor 25d increases as the flowing- out resistance of the pressurized oil becomes high, pressures in the vicinity of the lower portion of the fluid restirctor 25d and the oil passage 25b decrease, the supplying body gets force in the upper direction and is apt to return to the concentric condition. The concentricity of the supplying body and the rotary valve 5 can be kept by the concentric action and the avoidance of offset load due to pressure balanced arrangement by the oil passage 25b and the fluid restirctor 25d.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical recording/reproducing method and device capable of surely reproducing the information by preventing the generation of residual magnetic field due to the hysteresis of a magnetic core of a magnetic coil. SOLUTION: After the recording operation or erase operation is finished, the magnetic core of the magnetic coil 29 is degaussed in such a manner that the magnetic field generated from the magnetic coil 29 is alternated and attenuated by supplying the AC current to the magnetic coil 29 of the magneto-optical recording/reproducing device 100 while gradually attenuating it. By this procedure, the generation of the residual magnetic field due to the hysteresis of the magnetic core is prevented, and the residual magnetic field does not be impressed on a medium 10 at the time of information reproduction. Therefore, this device is extremely suitable for the device to record/reproduce the medium reproducing the information without impressing the reproducing magnetic field at the time of information reproduction like the CAD type magneto-optical recording medium.
