Title: Manufacture of semiconductor device
Inventor: KUSAKA TAKAHISA
IPC: H01L21/30
Filed: 1985-11-22
Abstract: PURPOSE:To increase the reliability of a MOS-type semiconductor device which is manufactured by an electron beam direct image drawing method or an X-ray exposure method, by forming an insulating film contacting with a semiconductor substrate with silicon oxide nitride film, and performing an oxygen annealing. CONSTITUTION:Except the forming method of a gate insulating film, conventional technical arts are used. After an insulating film 2 for element separation is formed on the surface of a P-type Si substrate 1, the gate insulating film 3 is formed. Successively an oxygen annealing is performed under the conditions, for example, at a temperature of 1,000 deg.C, for about 20min and O2=5l/min, and the gate insulating film is completed. Then a poly Si gate 4 is formed, and a source.drain diffusion layer 5 is formed by an ion implantation. Thus a MOS transistor is constituted. Electron beam direct image drawing method is applied to all the lithography technology in this manufacturing process.

Title: Method for analyzing catalyst component for purifying exhaust gas
Inventor: TAKAYAMA OSAMU
IPC: G01N23/20
Filed: 1990-09-28
Abstract: PURPOSE:To accurately meaure the particle size of a Pt component by eluting and separating Pt from a catalyst carrier so that only Pt is not ionized by a minertal acid and separating and concentrating Pt from the mineral acid solution to subject the same to X-ray diffraction. CONSTITUTION:When a catalyst carrier 5 is immersed in a mineral acid solution 7, a component other than a Pt component is ionized but Pt is not dissolved and, therefore, Pt is separated without being ionized. By this method, the Pt component 8 is simply separated and conc. and the intensity of diffracted rays sufficient to measure the particle size of Pt can be obtained.

Title: Measurement for discharge power of silent discharge system laser
Inventor: UBAHARA JIYUN
IPC: H01S3/0975
Filed: 1985-11-21
Abstract: PURPOSE:To make it possible to measure the discharge power on the basis of the area of a Lissajous's figure and the frequency of the power source by finding the area of the Lissajous's figure with the quantity of charge and discharge voltage of the capacitor to be charged with a discharge current as its parameters. CONSTITUTION:A dielectric or dielectrics 5 is/are applied on one side or both sides of electrodes 3 and 4 arranged facing each other in a vacuum container 2 in a silent discharge system laser 1. Therefore, when a high-frequency electric field (its frequency is 100kHz, for example) is made to act between the electrodes 3 and 4 using a power source 7 in a state that laser medium gas is flowing in a discharge region 6, the so-called silent discharge is generated between the electrodes 3 and 4. As this silent discharge makes the laser medium gas excite, a laser oscillation is generated in an optical resonator consisting of a totally reflecting mirror 8 and a partially reflecting mirror 9 and part of the oscillating light is taken out as a laser beam 10 through the partially reflecting mirror 9. The discharge power of such a silent discharge system laser is found on the basis of a Lissajous figure.

Abstract: PURPOSE:To provide a treating agent for soil stabilization preventing the generation of dust and contriving the improvement of its reactivity, miscibility and dispersibility, by containing a substance consisting mainly of quick lime, etc., and fibrillated polytetrafluoroethylene resin. CONSTITUTION:The objective treating agent is produced by compounding (A) a substance (e.g. soft calcined lime or salt-calcined lime) consisting mainly of quick lime and/or calcined dolomite and preferably having a powder or powdery particle form with (B) preferably partially fibrillated polytetrafluoroethylene resin as an effective component ordinarily in an amount of 0.01-1.0wt.% (preferably 0.03-0.5wt.%). When added to soil, the treating agent absorbs water in the soil and the component A reacts with the water to generate heat. The treating agent is mixed with the soil under stirring in the presence of the generated heat to fibrillate the component B by the compression/shearing actions. Thus, the particles of the produced slaked lime are respectively covered and agglomerated with the resulting cobweb-like net to stabilize the soil.

Filed: 1985-11-21
Abstract: PURPOSE:To reduce work load and prevent a decrease in work efficiency or any accident by allowing a paper holding cam to ascend automatically if the passage of a pedestal through a prearranged position is detected. CONSTITUTION:A paper holding cam 15 is enabled to ascend and descend by a paper holding cam lifting mechanism 24 which is driven by an air pump 26. In addition, a limit switch 23 is provided at both sides of a printing surface plate, and generally during printing, the paper holding cam can be moved by turning ON an automation switch regardless of the operation of a cam lift pedal 22. In this case, if a pedestal 16 is shifted, an actuation protrusion 27 on the pedestal 16 strikes the limit switch 23, and the paper holding cam 15 automatically descends to fix printing paper before passage of the pedestal 16 through a printing surface plate 13. Then after passage of the pedestal 16 through the printing surface plate 13, the paper holding cam 15 automatically ascends to release printing paper.

Filed: 1986-11-06
Abstract: PURPOSE:To automatically perform the multi-window processing at the side of a display device just by setting previously the simple and necessary instruction value into a memory set at the display device side from the side of a central processing unit after shifting totally the multi-window processing to the display device side. CONSTITUTION:A display control means (e) reads the corresponding instruction data out of a 3rd memory means (c) and a 4th memory means (d) in response to the data on a 2nd memory means (b) read out successively for each picture element. Then the means (e) selects the data on the corresponding display picture out of a 1st memory means (a) based on the instruction data, the data on the means (b) and a display position on a display device (f). The selected data is displayed at the corresponding display position of the device (f). In such a way, the multi-window processing is totally shifted to the side of the display device and therefore the device can perform automatically the multi- window processing just by setting the simple instruction value to a memory of the device from a central processing unit.

Title: Controller for piezoelectric pump
Inventor: NAKAMURA SATOSHI
IPC: H01L41/04
Filed: 1988-10-20
Abstract: PURPOSE:To make such accurate control that is quick in control reactivity performable by controlling a drive circuit on the basis of a comparison signal between a physical state of fluid and reference data, and changing the waveform of an alternating current being impressed on a piezoelectric pump. CONSTITUTION:When a target flow rate is designated by a designating means 24, a central processing unit(CPU) 12 reads out reference data Q0 as to the target flow rate from a data base 14. Next, the CPU 12 gives a command based on this reference data to a drive circuit 11, and according to this command, the drive circuit 11 outputs an alternating current S of frequency fi and voltage value vi. A piezoelectric pump 10 is driven by the alternating current S, feeding a fluid under pressure. Flow rate Q of this fluid is detected by a sensor 36, and a comparator 37 compares actual flow rate Q with the reference data Q0, and the result is sent back to the CPU 12. Accordingly, the CPU 12 dictates a change of the frequency and voltage value to the drive circuit if necessary so as to cause a difference between them to become zero. The above operation is continuously performed according to a pressure-feed progress of the fluid, so that the target flow rate is stably fed out of the piezoelectric pump 10 under pressure.
