Title: Ultrasonic wave transducer
Inventor: TODA KOJI
IPC: H03H9/145
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To convert an elastic wave propagated in the interior of a non- piezoelectric plate into an electric signal efficiently in a short reply time by propagating the elastic wave to the interior of the non-piezoelectric plate efficiently. SOLUTION: In the case of using an interdigital electrode 1 for an input electrode, when electric signals E1 , E2 with a phase difference are given between an electrode I1 and a ground electrode 2 and between an electrode I2 and the ground electrode 2 via a phase shifter 5, an elastic wave of unidirectivity is excited in a 2-layer structure consisting of a piezoelectric ceramic plate 3 and a glass plate 4 and propagated in the glass plate 4. Furthermore, in the case of using the interdigital electrode 1 for an output, the elastic wave propagated in the glass plate 4 is converted into an electric signal in the interdigital electrode 1.

IPC: F02M37/00
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To surely prevent evaporative emission from flowing out to the atmosphere, open/close a valve without insertion of a fuel feeding nozzle, and simplify the piping. SOLUTION: A main valve 17 closes its top opening 13b by buoyancy of a valve main body 14 and an energizing force of a coil spring 19 so as to sealingly separate a tank inside from a fuel feed port and opens by hydraulic pressure of the fuel flowing from the fuel feed port in feeding the fuel so that the fuel can be replenished by communicated with an external flow path 15. A subvalve 18 controls fuel inflow from the fuel feed port to the tank in fuel feed and when a fuel cap is opened for fuel feeding, it is closed by differential pressure between the atmospheric pressure and the tank internal pressure so that the evaporative emissions in the tank are prevented from flowing out to the atmosphere.

Title: Construction of underwater structure
Inventor: YOSHIDA YOJIRO
IPC: E02D29/063
Filed: 1992-08-06
Abstract: PURPOSE:To enhance the easiness in execution of works by laying a running path on the underwater bottom surface from the land via a slope prepared at a shore, transporting a structure fabricated on the land to the bottom surface using this running path, and installing the structure in place. CONSTITUTION:The underwater bottom surface 1 excavated to a required depth is graded with crushed stones, etc., and the existing structure 4 side is made in up-slope while the shore 2 is made in down-slope. On the bottom 1 a running path 5 is laid from the land via the slope at the shore. Unit structures 10 such as a tunnel section caisson fabricated at a land working base are placed on this running path 5, conveyed one after another to the bottom 1 using a propelling device such as hydraulic jack, winch, etc., and joined with the existing structure part 4 finally.

Title: Light emitting diode display
Inventor: FUJII TAKEHIRO
IPC: G09F9/33
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To diminish the space of light emitting diode displays even if plural pieces of these light emitting diode displays are lined up transversely by forming the shape of reflection cases to an approximate parallelogram inclined at about the same angle as the angle of the display figures composed of display segments. SOLUTION: The reflection case 5 and a lead frame 1 placed with light emitting diode elements 2 are completed by positioning the display segments 6 and the light emitting diodes elements 2 in such a manner that both correspond to each other and sealing these segments and elements with sealing resins, then cutting the lead frame 1 from a frame 4. Even if the display figures consisting of the display segments 6 of the reflection case 5 are inclined about 5 to 10 deg. in such a manner, the reflection case 5 of the light emitting diode displays have the shape of approximately the parallelogram inclined at about the same angle as the angle of the display figures and, therefore, the character pitch between the respective light emitting diode displays is made narrower than heretofore and the space occupied by the light emitting diode displays as a whole is diminished.  Even more, the character pitch of the displays of the surface packaging type is narrowed without the occurrence of camber.

Title: Wiring system of semiconductor integrated circuit
Inventor: YAMAGIWA AKIRA
IPC: H01L23/52
Filed: 1984-11-02
Abstract: PURPOSE:To reduce the size of a chip and to increase the integration of the chip by activating the gate electrode wiring layer of a block to enhance the utility of the intermediate wiring layer of the block of a chip center. CONSTITUTION:Since the wirings of a block 5 of the periphery of a chip are relatively small in the second layer wirings 10, 11 in a Y direction A1 between the blocks at the periphery of the chip, the second layer 9 in the block A1 is used. Accordingly, a cell 7 is disposed without spacing between the cells to reduce the block size. Then, the wirings of the block 6 at the center of the chip are more in the second layer wirings 10, 11 in Y direction A1 between the blocks at the center of the chip to be complicated. Consequently, the wirings are executed by avoiding the use of the second layer in the block A1. In other words, after the cells are spaced therebetween by considering the wirings exceeding the cell row to form the Y-direction wirings in the block in the silicide layer of a gate electrode in the disposition of the cell 7, the wirings in the block in Y direction is formed of the silicide layer. Then, the second layer in the block A1 is used for the wirings in the Y-direction between the blocks.
