Title: Improving method for fatigue strength of forming dies
Inventor: MIYAZAKI MASAYUKI
IPC: B21D37/20
Filed: 1978-05-11
Abstract: PURPOSE: To cancel the tensile stress generated while the forming work, to improve the fatigue strength of the dies, and to facilitate the selection of the shape of dies, by cooling the interior and heating the exterior of the forming dies while forming work, so as to generate a residual thermal compression stress due to the temperature difference.  
     CONSTITUTION: The heater 11 is installed round the outer circumference 7 of the dies 1, which is then heated to temperature T 1  by the power source 10; and the inner circufmference 8 is cooled to temperature T 2  with the liquefied nitrogen. Since the temperature difference T 1 -T 2  is positive, a plastic deformation due to the tensile stress is caused in the stress-concentration part 3 of the dies 1; therefore, when the temperature difference becomes none, a residual compression stress is generated in the stress-concentration part 3, and it cancles the tensile stress generated in the stress-concentration part 3 due to the compression at the forming work. Hereby, the fatigue strength of the dies 1 is improved, and the selection of the desirably designed dies, which was hitherto difficult, can be easily made.

Title: Measuring method for transient response characteristic
Inventor: NAGATA KOUHEI
IPC: H01L21/66
Filed: 1980-04-30
Abstract: PURPOSE:To obtain a high sensitivity for the DLT method to be used for measuring the deep  level in a semiconductor crystal by a method wherein a driving pulse is applied on the sample to  be measured, the ingredient generated by the driving pulse is removed from the output signal obtained and a transient response signal alone is picked out. CONSTITUTION:The driving pulse 16, which has been synchronized to a trigger pulse 15, is added to the gate 2 on a GaAsNES FET1, for example, and the output pulse signal 17 of the FET1  is outputted to a driving pulse removing circuit 14. This circuit 14 is operated in such manner that  it will be in the state of breaking while the main pulse 18 which is synchronized to the trigger  pulse 15 is applied. Accordingly, the output 19 of the circuit 14 is applied to an amplifier 4 when  it is turned into a transient response signal 21 alone after a driving pulse portion 20 has been removed from the output pulse 17. Subsequently, a sampling is performed on the initial value of amplification signal and the value obtained after the lapse of the prescribed period of time and the difference of the above two values is inputted to the Y axis of a recorder 8. The measurement is performed by changing the temperature of the sample and the desired data is obtained by inputting the temperature into the Y axis. Through these procedures, the amplification degree can  be increased and the sensitivity of measurement can also be improved without interruption by the  driving pulse having a large signal level.

Title: Color picture tube
Inventor: NAKAMURA KOUJI
IPC: H01J31/20
Filed: 1979-05-09
Abstract: PURPOSE:To expose a fluorescent screen with the same exposure device regardless of the arrangement of a digitally arrayed electron gun by matching a thinner wedged lens with the direction of the deaxialized length S in the digitally arrayed electron gun and exposing with a digitally arrayed light source. CONSTITUTION:Since the DELTAP' component of the landing error is an error which is commonly generated in tri-colors, it can be compensated with an optical lens. On the other hand, since the beam deflection compensation DELTAS' differs from each direction S of blue B, red R, and green G, it must be compensated using a wedged lens. Consequently, the fluorescent screen is exposed and sticked using a digitally arrayed light source, it is exposed, matching the thinner wedged lens with direction of the deaxialized length S in the digitally arrayed electron gun. By combining an electron gun with inline arrays with this fluorescent screen 2, a picture tube is completed. This reduces the necessary beam compensation and controls the generation of a color shift.

Title: Purification of medium oil used for rolling and processing metallic aluminum
Inventor: MATAGAWA KIYOUSUKE
IPC: B03C1/025
Filed: 1980-05-02
Abstract: PURPOSE:To remove fine particles of metallic Al from the titled medium oil while retaining the properties of the oil and thereby to purify the oil by a method wherein the oil contaminated with the fine particles of metallic Al is contacted at a predetermined feed rate to ferromagnetic fibrous wires which are placed in the magnetic field of an air-core coil in such a manner that the direction of the fibers is orthogonal to that of the field. CONSTITUTION:The medium oil contaminated with the fine particles of metallic Al is purified by a high-magnetic separator in the following manner. The oil is fed to the magnetic separator in which the ferromagnetic fibrous wires (steel wool) having a diameter of not larger than 20mu are placed in the magnetic field of the air- core coil in such a manner that the direction of the fibers is orthogonal to that of the field. In this case, it is necessary to set the intensity of the field to be not less than 1000 Oe and the feed rate of the oil in a separating chamber to be not higher than 20m/hr. Accordingly, the fine particles of metallic Al in the contaminated oil can be removed at a high removing rate, for instance, 93%.

Title: Manufacture of semiconductor device
Inventor: HONMA TSUTOMU
IPC: H01L21/306
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent interlayer films other than a hole-forming part from being etched, due to the fact that etchant infiltrates more than required into the interface between an interlayer film and a resist film at the time of performing wet-etching in forming the hole having a multi-layer structure. SOLUTION: In this method, inactive ions such as Ar ions are caused to hit the junction surface of a film, so as to strengthen and control the condition of junction between a resist film and a film to be patterned and between the films. In such a case, prior to forming the resist film on the surface of the first oxide film 3 and the second oxide film 5, which form the hole, the inactive ions 12 are caused to hit the junction surface. An SOG(spin on glass) film 4 is formed, and before forming the second oxide film 5, the inactive ions are caused to hit the surfaces of the first oxide film 3 and the SOG film 4. An adhered material 16 generated by hitting the inactive ions is removed by contacting a brush 14 with the surface of a silicon wafer 13 and rotating it, and at that time, pure water from a pure water jetting nozzle 15 is also used.
