Filed: 1990-06-20
Abstract: PURPOSE:To prevent the adhesion of metallic particles of large sizes at the edge parts of tools and near these parts by directing the edge parts of the tools toward the side opposite from an evaporating source. CONSTITUTION:The tools having the sharp edge parts, for example, many microdrills 8 are so mounted on the inner side of a supporting frame 16 that the respective edge parts 8a face the inner side. The supporting frame 16 is rotated and the metallic particles 6 are generated from the evaporating source 4 while a negative bias voltage is impressed to the supporting frame 16 and the microdrills 8 from an external bias power source 12. The generated metallic ions 6i turn round to the edge parts 8a of the microdrills 8 as well similarly in the other parts by passing the spacing of the supporting frame 16 and react with the gaseous nitrogen in the atmosphere, by which the nitride thin films of the metal are formed. The extreme heating of the edge parts 8a is averted and the film thicknesses of the thin films with which the edge parts 8a are coated are about the same as the film thicknesses in the other parts; therefore, the tools having a good cut are obtd.

Title: Shock wave generator
Inventor: KADOWAKI KAZUO
IPC: G01P15/00
Filed: 1989-06-23
Abstract: PURPOSE:To reduce higher harmonic superposing components by providing a shock wave generator with the thin layer of a viscoelastic substance provided on the back of the colliding surface of a piston and a restraining member for restraining the shear deformation of the thin layer of the viscoelastic substance while sandwiching the thin layer. CONSTITUTION:When the elastic body 5a of an impact head 5 collides with the colliding surface 13a of a piston 13 to push down the piston 13, the colliding surface 13a of the piston 13 is elastically deformed. At this time, since a force acts on the thin viscoelastic substance layer 18 side in contact with a restraining member 19 so as to obstruct a deformation whereas a force acts on the thin viscoelastic substance layer 18 side in contact with the back 13b of the colliding surface 13a of the piston 13 so as to extend the layer 18 by the elastic deformation of the colliding surface 13a, a shear deformation is generated in the thin viscoelastic substance layer 18. A viscous resistance against a shear deformation force is produced by the shear deformation in the thin viscoelastic substance layer 18. The vibration energy of the colliding surface 13a of the piston 13 is converted to heat energy by the viscous resistance to restrain the vibration. Thus, higher harmonic superposing components can be reduced.

Title: Paper-feeding method for calender metal fitting fixer
Inventor: BENIYAMA YUUJI
IPC: B65H3/04
Filed: 1980-11-18
Abstract: PURPOSE: To fix calender papers orderly without any temporary binding by sending in piled-up calender papers from the topmost paper successively until they  are in touch with a metal fitting.  
     CONSTITUTION: A plurality of calender papers P piled up are conveyed toward a metal fitting fixer A. When they come under a feeding roller 8, since the circumferential velocity of the roller 8 is greater than that of a belt 7, papers P are rapidly and seccessively sent from the upper part, and at first, the topmost one reaches to the inside of a bent part 1a of a metal fitting 1. Consequently, the driving force of the topmost paper P is reduced, and the second paper P is sent into the metal fitting 1 as sliding between the first and the third paper. During this operation, the first paper P is kept in its inserted state into the metal fitting 1, and the similar operation is repeated subsequently. When the last paper P is sent into the metal fitting 1, all paper ends of a copy of the calender are released from the roller 8. Simultaneously, sliding is given between the belt 7 and the lowest paper P, and calender papers are kept in their inserted state into the metal fitting 1 by the frictional force for finishing paper feeding.
