Title: Etching equipment
Inventor: GOMYO YOSHIO
IPC: H01L21/3065
Filed: 1991-04-08
Abstract: PURPOSE:To enable the etching of a very fine pattern on a thin film, by encapsulating gas of high thermal conductivity at several Torrs or lower in a hermetic space enclosed by an object to be etched and its support, and equiping the support with refrigerant piping. CONSTITUTION:After resist patterning, an X-ray mask thin film part 6 is fixed on an etched-object support 7 via an 0 ring 8, so as to be integrated with an Si wafer 4 and a retaining frame 5. Interposing a gap of 1mm or less the support 7 faces the thin film part 6. Gas of high thermal conductivity under a pressure of several Torrs or lower is introduced in the gap which is hermetically sealed by the 0 ring 8. The retaining stand 7 is equipped with a cooling pipe 10. Hence the heat generated at the time of etching is conducted to the support frame 5 side via the gas of a high thermal conductivity, and the object to be etched is quickly cooled. Thereby the etching of a very fine pattern is enabled on the thin film 6.

Patent JP-S551509-A (JP)
Title: Inspection method of gas cock with overflow preventing valve
Inventor: FUJIMOTO JIYUNYA
IPC: G01M99/00
Filed: 1978-06-20
Abstract: PURPOSE: To enable judgement of goodness or not of the cock to be surely done by displaying the maximum pressure loss and maximum flow rate when the overflow preventing valve of the cock has operated in correspondence to the set values.  
     CONSTITUTION: When a governor Z 1 , valve V 1  and laminar flowmeter A are interposed between the gas cock y to be tested and a pressure gas source and the opening ratio of the valve V 1  is gradually increased, then the flow rate increases. When the flow rate increases a fixed rate, the overflow preventing valve of the cock Y operates to stop the flow. The maximum pressure loss of this time is sensed with a pressure sensor N, and is converted to a voltage signal by a pressure transmitter 0. This signal is then transmitted to a digital panel meter R which indicates the maximum pressure loss. The change point of the pressure loss at this operation is held and the measured value is indicated in the meter R. At the same time, a lamp OK or NG is lighted for the upper limit value by a setter Q. Further, OK or NG display for the peak value of the working flow rate is accomplished with respect to the upper limit value and lower limit value of the setter G.

Title: Motor having commutator mechanism
Inventor: NAGATA YASUKAZU
IPC: H02K23/00
Filed: 1988-03-28
Abstract: PURPOSE:To obtain a stable rotary torque by circumferentially inclining commutator segments at a predetermined skew angle. CONSTITUTION:Commutator segments 4a-4d are planely of parallelogram shape, and bent in a circular arc shape. The segments 4a-4d are so disposed circumferentially at an equal interval as to maintain insulating states therebetween to be integrally molded with synthetic resin 6. The segments 4a-4d are inclined at a predetermined skew angle theta with respect to a line parallel to the axis of a rotor shaft 5. Accordingly, even if brushes 15 are slightly displaced at its set position at the time of conduction switching of exciting coil 2, the period of time in contact with the segments 4a, 4b or 4c, 4d is lengthened. As a result, they do not become non-excitation at the time of switching of the coil 2, and a conventional rotary torque drop does not occur. Thus, a stable rotary torque can be obtained.

Title: Thickness measuring device for sheet-like object
Inventor: ISOZAKI KENJI
IPC: G01B11/06
Filed: 1982-05-01
Abstract: PURPOSE:To measure the thickness of a sheet-like object, by detecting the high or low intensity of the light owing to interference that appears in transmitted or reflected light when monochromatic light of variable wavelengths is irradiated to said object as a function of the wavelength. CONSTITUTION:The monochromatic light irradiated to a film 6 is conduced to a photosensor 19 by repeating the reflection at an angle theta and the transmission through the film 6 in reflection parts 17 and 18. When the monochromatic light is transmitted through the film 6, the light is reflected partly on the front and rear surfaces of the film 6 and the transmittance thereof is changed by the interference of the reflected light and the rectilinear light. If the wavelengths forming the adjacent crest and crest of the wave of the transmitted light when a prism 13 is rotated and the monochromatic light of continuously varying wavelengths is irradiated to the film 6 are designated as lambda1 and lambda2, the relation l=(1/2ncostheta).[1/(1-lambda1)-(1-lambda2)] holds, and if the refractive index (n) of the film and the incident angle theta of the light are beforehand determined, the thickness l of the film 6 is determined continuously from the output E3 of an arithmetic part 19. The above-mentioned E3 is calculated from the signals E1, E2 corresponding respectively to the wavelength lambda and the quantity of the light transmitted through the film 6.

Title: Injection timing control for diesel engine
Inventor: FUKUYAMA TADASHI
IPC: F02D41/40
Filed: 1986-03-31
Abstract: PURPOSE:To control the firing lag interval to the minimum level at all times by calculating the firing lag interval based upon the difference between detected actual firing timing and actual ignition timing then controlling the fuel injection timing such that the calculated firing lag interval is minimized. CONSTITUTION:A firing lag interval theta is related to an injection timing INJT and a firing timing IGT as shown by a formula I, and it can be seen that there is an injection timing INJT for minimizing the firing lag interval theta. Consequently, even if the injection timing is varied, the difference of the firing lag intervals thetabefore and after the injection timing is eliminated (thetan+1-thetan=0), and the injection timing INJT is feedback controlled, with an area for minimizing the firing lag interval theta being employed as a demand area. Since it is controlled such that the firing lag interval is shortest over the entire operating area, vibration, noise, etc. of engine are reduced and the emission or the black smoke in the exhaust gas are prevented from increasing.
