Title: Manufacturing method of metallic short fiber
Inventor: NAKAGAWA TAKEO
IPC: B23P17/06
Filed: 1979-12-13
Abstract: PURPOSE: To produce high quality, extra-fine metallic fibers which are widely used as friction material, by forcibly destroying the surface of a block with a self-excited vibration tool.  
     CONSTITUTION: Thin layers 41 of a metal block 1 are raked up on a rake face 31 of a cutting edge 3. Given self-excited vibration to a tool 2, the cutting edge 3 is displaced in a direction separated from the surface of metal block 1. This displacement cancels the cutting margin and cracks 6 are forcibly produced on the layers 41 gathered up on the rake face 31. As the cutting edge 3 returns to the surface of metal block 1, the cracked portions 6 of the layer are momentarily shorne and discharged as completely fractured fibers 5. Extra-fine fibers 5 with a diameter of below 100μc are continuously produced in accordance with the vibration frequency, taking the aforementioned process as a cycle.

IPC: H01L21/3205
Filed: 1985-07-24
Abstract: PURPOSE:To protect insulating film from cracks by rendering the bond strength at the corners and periphery of a substrate greater than the thermal stress in a resin moulding process by a method wherein the width of Al wirings at such locations in defined to be not wider than 25mum. CONSTITUTION:The widths W1, W2 of an Al wiring 3 formed along the periphery and at the corners of a chip 1 are rendered so narrow that they may not undergo detrimental effects produced by thermal stress in a resin molding process. For example, the with W1 of the Al wiring 3 along the chip periphery is made to be not wider than 25mum. Again, the with W2 (as measured along the direction from a corner to the chip center) of the Al wiring 3 is made to be approximately 50mum wide. With the wiring width being set as such, there will be no poor performance attributable to cracks, which leads to the realization of semiconductor devices with their reliability enhanced.

Filed: 1992-05-29
Abstract: PURPOSE: To reduce stress generated on a diaphragm so as to extend the service life thereof by supporting at least most of the diaphragm working area between fluid compression and induction in a piston device. CONSTITUTION: A peripheral portion 4a of a piston head 4 extends to and engages with a peripheral portion 8a of a diaphragm 8 to reduce the volune of a vacuum chamber 3 when a piston 1 descends from the TDC (Top-Dead- Center) position. The oil stored in the vacuum chamber 3 is pressed out and returned to an oil tank 13 via an oil bore 31 and a non-return valve 30. When the piston head descends, the pressure in a liquid chamber 20 is increased and the engaged portion of the peripheral portion 8a of the diaphragm and the peripheral portion 4a of the piston head 4 expands simultaneously. The diaphragm 8 approaches a wall surface 23 of the liquid chamber 20 and compressed liquid is discharged through an outlet valve 25. Thus, the portion of the diaphragm that is not supported is reduced during the working period of the piston, therefore, the total stress on the diaphragm is reduced.
