Title: Method and device for blast work
Inventor: MASE KEIJI
IPC: B24C9/00
Filed: 1990-07-31
Abstract: PURPOSE:To completely remove dust or the like sticking to a workpiece by feeding high temperature steam to a nozzle, facing into a blast work processing tank, or to a nozzle in an afterblow processing tank, provided successively in line with the blast work processing tank, and jetting this high temperature steam to the workpiece through the nozzle to remove extraneous matter sticking to the workpiece. CONSTITUTION:Extraneous matter of dust, oil film, etc., being charged with static electricity generated by blast work, adheres to surfaces of a workpiece W, but when high temperature steam, fed by a high temperature steam supply source 12, is blown to the workpiece W through a nozzle 50 in a blast work device 30, the extraneous matter sticking to the workpiece is blown off by the high temperature steam. Simultaneously with the above, static electricity, with which the sticking matter and the workpiece are charged, is discharged, so that dust, detached from the workpiece to float in the air, is prevented from adhering again to the workpiece and dropped down.

Filed: 1990-07-31
Abstract: PURPOSE:To allow the easy manufacture with a simple structure and stably obtain an emission current for a long time by constituting the emitter electrode by a whisker having a multiaxial needle crystal part. CONSTITUTION:An emitter electrode 14 is formed by a whisker 13 having a multiaxial needle crystal part. In the whisker 13, the diameter of the needle crystal part is less than several mum, and the radius of, curvature in the top part is several hundred-several thousand Angstrom . When the whisker 13 is used in the emitter electrode 14, thus, the emitter electrode 14 having an extremely sharp top part can be obtained, so that the electron emission starting voltage can be reduced, and more emission current can be taken out from the emitter electrode 14. As the emitter electrode 14 has the multiaxial needle crystal part, also, the top part can be easily turned in the direction of a gate electrode 15. Thus, the manufacture can be easily performed with a simple structure, and the emission current can be stably obtained for a long time.

Title: Machine tool
Inventor: HANSU HENINGU BUINKURAA
IPC: F16C29/02
Filed: 1990-07-31
Abstract: PURPOSE: To allow a guide for machine parts to have constant characteristic damping to guide the machine parts in a shape fitting manner in coordinate directions by splitting a shoe along a horizontal plane, and guiding the upper and lower parts of the shoe by use of the upper and lower faces of a projection. CONSTITUTION: A shoe 20 is split into two along a horizontal plane 40, and the upper part 30 is guided by the upper face 52 of a projection 17 and the lower part by the lower face of the projection 17. This constitution allows the guide of a machine tool having synthetic resin pads 46, 48, 50 to have natural characteristic damping, either to prevent the transmission of great vibration resulting from a machining process with a large amount of removal of cutting, from one machine part to the other machine part, or to transmit the vibration while strongly damping it. The guide of the shoe 20 by use of a guide rail 11 having the projection 17 is utilized to enable the machine parts to be guided perpendicular to the longitudinal direction of the guide rail 11 in a shape fitting manner in any coordinate directions.  This is effective when an upward force, e.g. the repulsive force of the tool, is applied perpendicular to the guided machine parts, particularly if the guide rail 11 extends horizontally.
