Title: How-to-determine recessing method in numerical control information making function
Inventor: YAMAMOTO KYOICHI
IPC: G05B19/4093
Filed: 1989-12-13
Abstract: PURPOSE:To facilitate the determination of a recessing method by extracting a form element whose recessing is designated, and constituting it to automatically determine the type and sequence of a manufacturing process and the recessing range according to each feature of forms of the groove form element and the adjacent form elements. CONSTITUTION:An operator operates a control panel 6 as checking each of input contents with a display unit 5, and stores each form of materials and parts into a storage memory 3. A processor 1 extracts a form element whose recessing is designated in form element lines on the basis of a program stored in a control memory 2, thereby determining each of working conditions and tool types automatically. This determination depends upon the presence of a shift groove and a recessing range, length of a groove form element other than a groove cover, or the like. On the basis of information on the working conditions, tool types determined as the above, and process types and the working range registered in a temporary storage memory 4, the processor 1 produces numerical control information on the recessing, storing it in a storage memory 8. Accordingly, the desired recessing can be easily done by the numerical control information stored in this memory.

Title: Method of manufacturing semiconductor device
Inventor: ITO RYOICHI
IPC: H01L29/73
Filed: 1999-11-15
Abstract: PROBLEM TO BE SOLVED: To improve a frequency responsibility of a transistor, especially a vertical PNP transistor, in other words, to increase a cut-off frequency fT, in the manufacture of a semiconductor device including a bipolar transistor having a high cut-off frequency. SOLUTION: A P-type diffusion layer serving also as a side face collector region of a vertical PNP transistor is formed by vertically etching an N-type epitaxial layer which constitutes the vertical PNP transistor. Then, the P-type diffusion layer is formed on its side wall with an oxide film and then is filled with high melting point metal. The side face collector region itself is reduced in resistance and its width and diffusion depth, which have been expanded in a thermal diffusion, are not expanded. As a result, a parasitic capacity of the diffusion layer of the side face collector region is reduced and a collector capacity is also reduced as a whole, increasing a cut-off frequency fT of the vertical PNP transistor.

Title: Surface finishing method for grooved part
Inventor: TANIGAKI MASABUMI
IPC: B24B31/00
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent abrasive from entering into a groove of a part having a groove during grinding and to eliminate requirement of operations for removing the abrasive from inside of the groove after finishing of grinding. SOLUTION: When a surface of a part 1 having a groove is ground by a barrel process, filler 3 made of water soluble resin is previously filled into the groove 2 of the part 1 having the groove. By relatively moving the part 1 having the groove and abrasive in this condition, abrasive can be prevented from entering into the groove 2 of the part 1 having the groove during grinding. When the part 1 having the groove is soaked into a water tank after finishing of grinding in the condition that the filler 3 remains to be charged, the filler 3 solves in the water due to its water solubility and is removed from inside of the groove 2. At this time, by adding ultrasonic vibration to the water, micro cut powders adhered to the surface of the part 1 having the groove are removed.
