Title: He-ne gas laser tube
Inventor: SEKI FUMIO
IPC: H01S3/03
Filed: 1980-11-12
Abstract: PURPOSE:To suppress a wave of 3.39mum length oscillating in competition with a wave of 0.6328mum length in an He-Ne gas laser tube by utilizing a magnetic field generated by a magnetic substance which is magnetized by a magnet. CONSTITUTION:Magnetic substances 5-5''' are fixed on a case 3 by means of screw thread structure, their tips are placed near a narrow tube region 1' of an He-Ne filled tube 1, and other tips are placed in contact with magnets 6-6''' at the surface of the case 3. The magnetic substance generates magnetic field at a tip by magnetization of the magnet, and oscillation in 3.39mum wave length can be suppressed efficiently by Zeeman effect due to magnetic field. By mirrors 7, 7' disposed at both sides of the case and by a high voltage applied between lead wires 8, 9 for an anode and a cathode of the gas filled tube, a laser light 10 is brought out. By this constitution because the magnetic substance can be maintained in the vicinity of the narrow tube region of the gas filled tube and because a magnetic field to suppress the wave of 3.39mum length is applied efficiently on a laser oscillation medium, a magnet is reduced into a small size, and a laser tube can be formed in a small size.

Title: Trim flange press die
Inventor: MATSUSHIMA MORIKATSU
IPC: B21D19/08
Filed: 1980-11-12
Abstract: PURPOSE: To enable one process work preventing generation of burrs and early wastage of punches and dies by holding a blank with an energized movable second pressure plate to check coming up of the blank, and making flange work and blanking after making it precede completely.  
     CONSTITUTION: By descent of a punch holder 7, the second work pressure plate 10 comes into contact with a blank 12 on the first work pressure plate 5, and the blank 12 is pressed and fixed elastically by pressure plates 5, 10. Since elastic supporting power of the pressure plate 10 is set smaller than that of the pressure plate 5, the pressure plate 5 maintains stationary state and keeps the same height with a die 2. When the holder 7 further lowers a punch 8 contacts with the blank 12 and blanks it with the die 2. The pressure plate 10 comes into collision with the lower face of the holder 7 to become the limit of ascent. When the pressure plates 10, 5 go down in a united body by further descent of the holder 7, the pressure plate 5 lowers resisting against elastic supporting power, flange working of the blanking edge 12a is made between the edges of the pressure plate 10 and die 2.

Abstract: PROBLEM TO BE SOLVED: To provide a wide image in which a sense of incongruity is less by configuring a read control signal with a count of different clocks in response to a position on a horizontal scanning line. SOLUTION: Let an extension rate of a picture element in the middle for each horizontal scanning line be 1 and picture elements are read and displayed so that the extension rate is continuously changed in the horizontal direction.

A multiplier section 3 receives the absolute value |X-b| and a prescribed constant (a) and provides an output of a|X-b≫. A 2nd adder section 4 receives the output a|X-b| and a prescribed constant (c) and adds them and provides an output of characteristic equation Y=c-a|X-b|.  The characteristic equation is added to a 3rd adder section 5 as Y=ΔX, then an address K based on the count is obtained and the address K is fed to a memory section, from which picture elements are read to obtain an image whose extension rate is changed continuously in the horizontal direction.

IPC: G06F9/32
Filed: 1994-06-17
Abstract: PURPOSE:To make a user feel none of a click noise, delay, and distortion when a voice program is dynamically assigned to an MSP memory. CONSTITUTION:An NOP controller 500 which assigns the voice program from a host memory 11b to the MSP memory 12b dynamically in read time is provided. The NOP controller 500 make execution disabled by temporarily varying the memory capacity by masking instructions stored in locations in the MSP memory 12b to which the voice program is assigned. Namely, the host CPU 20 of a host processing module 11 dynamically assigns the voice program, selected on a keyboard, etc., from the host memory 11b to the MSP memory 12b and the NOP controllers 500 transfers the program to the masked memory locations. Therefore, other voice programs in the MSP memory 12b are not masked by the NOP controller 500, so that they are continuously executed without being affected by the dynamic assignment. Thus, the user feels none of a click noise, delay, and distortion.

Title: Semiconductor device and its manufacture
Inventor: INOUE TOMOTOSHI
IPC: H01L21/3205
Filed: 1987-06-29
Abstract: PURPOSE:To avoid the possibility of wire breaking due to electromigration, by using a wire whose surface is covered with a high hardness metal layer containing heat-resisting metal. CONSTITUTION:On the whole surface, a first metal layer 7 composed of WN is spread by a method like sputtering. A metal layer whose main component is Al, e.g., Al-Cu layer which is low-resistive and excellent in workability is spread on the whole surface. Thereon, a second metal layer 9 of WN is spread. A third metal layer 10 is subjected to anisotropic etching by applying RIE, and only the side-wall part of a wiring part formerly formed is left. As the surface of the metal layer 8 whose main component is Al is protected by the metal layers 7, 9, 10 containing heat-resisting metal of high hardness, hillocks do not generate in a thermal process. Thereby, the possibility of wire- breaking due to electromigration is reduced.

IPC: H01L21/66
Filed: 1994-07-12
Abstract: PURPOSE:To obtain a foreign matter removing apparatus for removing foreign matters locally deposited on the surface of a member. CONSTITUTION:A foreign matter removing section 8 is mounted to a block 7, which is guided to move along the surface of a member 2 having the substantially flat surface at least in one direction, to slide on the surface of the member 2 in order to remove foreign matters deposited on the surface thereof. Good contact between the foreign matter removing section and the member can be assured by inclining the foreign matter removing section 8 in the moving direction and rotating the block 7 mounting the foreign matter removing section 8 around the guide shaft 8a. Therefore since foreign matters can be removed surely only by causing the foreign matter removing section 8 to slide on the surface on which foreign matters are deposited, the periodical foreign matter removing work using a plishing member is no longer required, removal and remounting of the member 2 from which the foreign matters are removed is unnecessary and discrepancy resulting from deviation of remounting position can be eliminated.
