Title: Manufacture of surface acoustic wave resonator
Inventor: FUJIWARA YOSHIAKI
IPC: H03H3/08
Filed: 1987-07-17
Abstract: PURPOSE:To improve the reflecting efficiency of a grating reflector and to miniaturize a surface acoustic wave resonator, by performing etching after the polarization axes in the area of a substrate, where reflecting elements are formed, are inverted to the opposite direction when the reflecting elements of the grating reflector are formed on the substrate, on which a single polarization process is performed and the polarization axes are oriented in the same direction. CONSTITUTION:When the reflecting elements 31 of the grating reflector 3 are formed on the substrate 1, on which a single polarization process is performed and the polarization axes are oriented in the same direction, the polarization axes in the area on the base plate 1, where the elements 31 are formed, are inverted to the opposite direction and chemical etching is performed on the axes. Then grooves are formed at the parts where the polarization axes are inverted. Since such groove forming method does not required any mask, the reflecting elements 31 composed of the grooves having high reflecting efficiencies can be formed easily. Moreover, this surface acoustic wave resonator can be miniaturized since the number of the reflecting elements 31 constituting the grating reflector 3 can be reduced and, at the same time, the occurrence of an internal loss and spurious caused by bulk waves radiated at the boundary of a metallic electrode can be reduced.

Title: Guide light method
Inventor: HIRAMOTO JIYUNICHI
IPC: G02B27/40
Filed: 1983-09-27
Abstract: PURPOSE:To superpose visible light on invisible CO2 laser light and to use the superposed light for indicating the position to be irradiated by forming an optical waveguide for visible light into a tube and passing an IR fiber therein. CONSTITUTION:An IR fiber 3 is passed into a tube 6 consisting of a material which allows transmission of visible light, for example, PMMA (polymethyl methacrylate), etc. The PMMA tube is slit up to the mid-way and the IR fiber is taken out through the slit and is used as an incident end for CO2 laser light. The part 70 of the tube is distributed with the refractive index higher than the refractive index on the inside 71 and outside 72 thereof. The end of the tube on the side slit for the purpose of incidence of visible light is thermally worked to form the construction which is not tubular but circular columnar in section and to which light is made incident effectively. Visible light is thus always focused at one point on the focal plane and is made annular in the parts except the focal plane, by which the presence of IR light in said ring is distinctly indicated. Easy assembly is made possible simply by inserting the IR fiber in the case of manufacturing the IR fiber with indicating light.

Title: Discharge device for bookbinding machine
Inventor: KOJIMA NOBUYUKI
IPC: B42C11/04
Filed: 1992-05-27
Abstract: PURPOSE:To conserve a space by a method wherein the book body falling from a clamper is received by an up-and-down movable conveyor and transferred to a fixed conveyor by lowering the up-and-down movable conveyor to be fed and the up-and- down movable conveyor is raised to the original position after the completion of the transfer of the book body. CONSTITUTION:When a clamper 1 clamps a book body 2 to reach a discharge position, a shaft 6 moves to release the clamping of the book body 2. At the same time, a rotary shaft 11 is rotated to rotate an arm 14 in a counterclockwise direction through a cam 12 and an up-and-down movable conveyor 9 begins to fall. By this constitution, the book body 2 is received by the up-and-down movable conveyor 9 without receiving an impact. The up-and-down movable conveyor 9 falls to move in the moving direction of the clamper 1. Therefore, the book body 2 is obliquely downwardly moved in the moving direction of the clamper 1 and reasonably delivered to the up-and-down movable conveyor 9 to be moved to the lowermost position. During this period, a cover 3 is applied to the book body 2 by an erection mechanism. Subsequently, the leading end of the book body is placed on the fixed conveyor 30 running a slightly faster speed to be fed by the fixed conveyor 30. After the completion of the transfer of the book body, the up-and-down movable conveyor 9 returns to the original position.

Title: Method of manufacturing cathode ray tube
Inventor: ODAKA YOSHIYUKI
IPC: H01J9/22
Filed: 1983-09-30
Abstract: PURPOSE:To apply liquid material to the inner surface of a face plate without unevenness and to enable to form a uniform coating on it by rotating the face plate, of which the inner surface is downwardly directed, and injecting the liquid material for forming the coating to the inner surfasce from a supplying nozzle which is vertically and upwardly positioned. CONSTITUTION:A face plate 1, of which the inner surface is downwardly directed, is positioned and liquid material for forming a coating such as graphite suspension and so on is injected from a supplying nozzle 2, for example, with 6mm. of the inside diameter, which is positioned under the face plate so as to be upwardly directed to generally correspond to an axial direction of a tube. If the flow rate is reduced and in case of setting the flow rate under 3l/min., it is impossible to completely apply the liquid material to peripheral portions of the face plate and therefore the unevenness of application is caused, but it is possible to evenly apply the liquid material to the whole surface of the face plate by rotating the face plate 1 with a speed of about 80rpm as the axis of the tube is a center axis. Further, the excessive liquid 4 is collected into a container 3.

IPC: G01S15/58
Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To implement CW Doppler operation for an ultrasonic apparatus using multi-element transducer array. SOLUTION: The system has an ultrasonic probe 6, transmission beam shaping device 7, analog preamplifier 8, A/D converter 10 and is equipped with a system controller 20.

The signal is demodulated by a demodulator 14 and the image signal is supplied to a scan converter 16. Further, dither signals are added to the received echo beams before being digitized by the ADD converter. Thus, capability to detect low-amplitude signals is enhanced and a dynamic range of the A/D converter is enlarged.

Abstract: PURPOSE:To improve GaAs MESFETs in reproducibility and uniformity of their electrical characteristics by a method wherein an FET-forming region on an S.I.GaAs substrate is protected from damage attributable to plasma-using dry etching in a GaAs MESFET manufacturing process. CONSTITUTION:On an AlN layer 5, an SiO2 layer 6 is formed as a spacer insulating film. Next, the SiO2 layer 6 is subjected to dry etching with a photoresist 21 serving as a mask, when a Schottky gate-forming region on the surface of an S.I.GaAs substrate 1 is protected from damage because it is covered by the AlN layer 5. A high-melting metal layer 7 is formed on a Schottky gate opening and SiO2 layer 6 and, for the elimination of abrupt steps, flattening photoresist is applied. A plasma-using dry etching process is accomplished for the removal of the high-melting metal layer 7 from above the SiO2 6, when the surface of the S.I.GaAs substrate 1 is protected from damage because it is covered by the AlN layer 5 and the high-melting metal layer 7. The remnant of the SiO2 layer 6 or of the AlN layer 5 is removed for the formation of a Schottky gate 8 in a prescribed region.
