Title: Flap type servo valve device
Inventor: NAKAMURA KIYOUICHI
IPC: F15B13/04
Filed: 1981-11-11
Abstract: PURPOSE:To prevent generation of a throttling sound by forming an outflow nozzle slantingly in the direction of a small gap in a throttle passage between a side wall and a valve seat. CONSTITUTION:As for the size of gaps between a side wall 26a of a main valve member 20 and a valve seat 34 whieh is in a slanting condition to said wall 26a, an exterio gap delta2 is bigger than an interior gap delta1. Accordingly, pressurized fluid from an outflow nozzle 31 opening in the side wall 26a flows out at high speed into a valve chamber 26 of low pressure through a throttle passage 50 between the valve seat 34 of a flap valve 38 and the side wall 26a with special tendency to flow toward the exterior part with a big gap. However, since the outflow nozzle 31 is formed slanting in the direction of a small gap, that is, relative to the side wall 26a by an angle, outflow to the exterior is difficult and the same to the interior is easy. As a result, pressurized fluid from the outflow nozzle 31 flows out spreading about evenly on the whole periphery of the valve seat 34. Thus, not only cavitation but also generation of throttling sound are prevented.

Title: Inspecting defect of transparent thin film pattern
Inventor: MATSUYAMA YUKIO
IPC: G01B11/245
Filed: 1985-08-21
Abstract: PURPOSE:To surely inspect the defect of a pattern, such as a thin photoresist film residue, by selecting three kinds of light with wavelengths different from one another and calculating differences in the intensity of reflected lights. CONSTITUTION:Light from an irradiation source 11 is incident onto an objective lens 14 via a condenser lens 12 and a half mirror 13 and irradiated on a wafer 15 to be inspected on X-Y table 16. The wafer 15 comprises an Si wafer formed with an SiO2 thin film thereon and a photoresist pattern to be inspected on the SiO2 thin film. The light reflected from the wafer 15 is again transmitted through the lens 14 and the mirror 13 and spectroanalytically processed into three wavelength bands by dichroic mirrors 17a and 17b and then, after the wavelengths are restricted by optical filters 18a-18c with different wavelengths from one another, imaged by photoelectric transducer elements 20a-20c. The images thus obtained are corrected by magnification correcting lenses 19a-19c to equalize the magnifications of three images so that the magnification error due to chromatic aberration is not produced among image patterns. The output images 21a-21c from of the three elements 20a-20c, respectively, are arithmetically processed by a signal processor and the defect of photoresist film reside is detected.

Title: Impeller
Inventor: TOMOHIRO TERUHIKO
IPC: F04D29/30
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To retain performance over wide operating points by easily producing a rounding flow at a front edge and suppressing separation at the front edge. SOLUTION: This impeller has a structure that a blade 4 is annually arranged on a main plate and the other end is supported by an auxiliary plate, and the blade 4 is formed into a shape that its blade shape in a cross section cut by a surface perpendicular to a rotary shaft has an approximately semicircular projected part 19 on the back surface side 15 of the front edge 13. Therefore, even though the radius of the front edge 13 is increased and a flow inflow angle and a blade inlet angle are slightly shifted from each other, round flow at the front edge 13 is easily produced. Therefore, even though the inflow angle is slightly changed by a flow condition, sudden separation at the front edge 13 can be suppressed, thus performance can be retained over wide operating points.

Title: Thermosensitive recording head
Inventor: TANMACHI HARUO
IPC: H01C7/00
Filed: 1983-09-29
Abstract: PURPOSE:To form a thermosensitive recording head which is improved in the oxidation resistance of a resistance film while combining reproducibility and stability in the manufacture thereof by modifying the resistance film itself. CONSTITUTION:When a resistance film for heat generation is provided on an insulation substrate 1 to build a thermosensitive recording head, the lower layer resistance film 7 employs a resistor which enables production high in the producibility but less in the oxidation resistance while the upper layer resistance film 8 employs a resistor excelling in the oxidation resistance but less in the reproducibility and stability. With such an arrangement, the resistor itself can be made excellent in the oxidation resistance. Thus, improving the oxidation resistance in the resistor itself can eliminate any oxidation resistant layer as protective layer and hence, providing a wear resistant layer 5 along suffices for this purpose.

Title: Meter and method for measurement of film thickness by infrared rays
Inventor: MORISHIGE KIYOSHI
IPC: G01B11/06
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To obtain a meter whose accuracy is enhanced and by which a measurement is performed simply by a method wherein two P-polarized infrared beams are made incident on a film, to be measured, at an angle of polarization or an angle of inclination close to it in such a way that they are crossed with each other at a specific angle. SOLUTION: Infrared light from a projection part 12 is passed through a linear polarizer, and it is changed into P-polarized beams 24, 26 so as to go out from projection windows 16, 18. The two P-polarized beams 24, 26 are crossed at an angle close to 90 deg. on a film 10 so as to be incident on the film 10 at an angle of polarization. A light-receiving part 14 receives the two beams 24, 26 so as to be converted into electric signals by an infrared detector. The electric signals are converted into signals which are proportional to the intensity of transmitted light, and the two signals are added so as to be sent to a data processing part 28. In the data processing part 28, an absorbance is found from light-received data on the basis of Lambert-Beer's law, and the thickness of the film 10 is decided.  In a measuring apparatus, since the P- polarized beams are incident at the angle of polarization, no multiple reflection is generated inside the film 10.

Title: Dry etching
Inventor: KATSURAGI MASARU
IPC: H01L21/302
Filed: 1989-07-14
Abstract: PURPOSE:To reduce a dependence property of an etch rate of a silicon dioxide film on a contact hole diameter by a method wherein a selective ratio of the silicon oxide film to a resist is lowered in such a way that an aspect ratio of an opening part does not become large. CONSTITUTION:A selective ratio of silicon dioxide film to a resist is lowered in such a way that an aspect ratio of an opening part does not become large; thereby, a drop in an incident efficiency of ions is reduced. That is to say, an etching rate of the silicon dioxide film is proportional to the incident efficiency of the ions; when the incident efficiency is lowered, an etch rate is lowered; the incident efficiency of the ions depends on the aspect ratio; when the aspect ratio becomes large, the incident efficiency is worsened; although an etching rate of substratum Si depends on the incident efficiency of the ions, a CF polymer is hard to stick when the incident efficiency is worse and the etching rate of the Si is increased unlike the silicon oxide film. Consequently, it is possible to restrain a selective ratio to Si from being lowered when the incident efficiency of the ions is increased. Thereby, a dependence property of the selective ratio of the silicon oxide film and the substratum Si on a contact hole diameter (aspect ratio) is reduced.
