Title: Atomizing pump
Inventor: YAMAMOTO KAZUSHI
IPC: F23D11/34
Filed: 1984-01-25
Abstract: PURPOSE:To obtain stable atomization characteristics by making the knot of the oscillation system of a nozzle plate constant, by providing a cut groove to the part, which is coincided with the knot part forming position of the oscillation system generating flexural oscillation, on the surface of the nozzle plate. CONSTITUTION:When an electric oscillator 1 is oscillated by the application of voltage from an oscillation circuit, a nozzle plate 3 is vibrated through a fixing layer 4b to perform flexural oscillation and, therefore, the liquid allowed to fill a liquid chamber 8 is pressurized to be atomized through nozzle orifices 6. Because this atomization is dependent on vibration characteristics, a cut groove 10 is provided to the knot part forming position of the oscillation system on the surface of the nozzle plate 3 in order to stabilize the vibration characteristics of said nozzle plate 3. By this method, the rigidity of the part of the cut groove 10 is lowered and the flexural oscillation at the center of the nozzle plate 3 is easily converted to vibration motion at the cut groove part as the starting point and, because the knot of the oscillation system is made constant at this position, atomization characteristics are stabilized.

Inventor: KAKINUMA YUKIO
IPC: G01N29/24
Filed: 1983-01-31
Abstract: PURPOSE:To detect a flaw precisely even when a flaw detecting surface is rough by inserting a flexible film from the periphery of an ultrasonic wave transmitting surface of an ultrasonic flaw detecting probe having a water feeding hole to the inside and pressing the film against the flaw detecting surface by liquid pressure inside the probe to prevent liquid leakage. CONSTITUTION:The water feeding hole 3 is formed on the ultrasonic probe 1 storing a transmitting/receiving vibrator and a flexible film 4 such as plastic is fitted to the probe 1 by a wear resistant metallic jig 5. The film 4 is inserted from the periphery of the ultrasonic wave transmitting surface of the probe 1 to the inside and is pressed against the flaw detecting surface 6 by water feeding pressure from a water feeding pipe 2 to prevent water leakage from a liquid staying space 7. Since the film 4 is sufficiently pressed into contact with the flaw detecting surface 6 even if undulation exists in the flaw detecting surface 6, liquid leakage is prevented and the ultrasonic transmittig surface can be precisely filled with the liquid, so that precise flaw detecting can be attained.

Abstract: PURPOSE:To attain the high speed movement of each head by making an optical head and a magnetic head movable individually and detecting and controlling the relative position of the heads through the detection of a transmissive light from the optical head. CONSTITUTION:When the movement of an optical head 4 is started by a seek instruction from an external device, a laser beam 6 with weak power from the head 4 irradiates a disk 2, its reflected light is detected by a photodetector 10 in the head 4, the number of track slots of the disk 2 is counted and a linear motor 14 moves the head up to a desired track accordingly. In this case, a part of the laser beam 6 is transmitted through the disk 2, detected by the photodetector 10 having two-split light receiving faces 10a, 10b in the magnetic head 7 and the difference of the detection signals of the light receiving faces 10a, 10b is obtained by a differential amplifier 11. Then the linear motor 15 is subjected to feedback control so as to make the difference zero, thereby tracing the head 7 to the head 4. Thus, the weight of the movable part is made light.

Title: Manufacture of enameled copper wire
Inventor: UNO NAOKI
IPC: H01B13/16
Filed: 1978-02-08
Abstract: PURPOSE: To obtain a highly flexible enameled wire by the procedure in which a  pure copper coarse wire containing usual impurities is drawn at a processing rate of  less than 90 %, annealed, and then drawn further into a desired diameter wire.  
     CONSTITUTION: A pure copper coarse wire containing usual impurities is drawn at  a processing rate of less than 90 %, annealed, and then drawn further into a desired diameter wire at a processing rate of 10 to 40 %. And, the wire thus obtained is  subjected to an enamel baking process. By taking advantage of the fact that the  flexibility of completely softened pure copper wire is greater, the lower the processing rate, the processing rate before annealing is set up to less than 90 % to prevent  recrystallization and aggregation upon annealing, thus preventing the lowering of  flexibility due to enamelling. Thus, it is possible to obtain enameled copper wire  having excellent flexibility.

Title: Semiconductor element mounting board
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L21/60
Filed: 1990-01-23
Abstract: PURPOSE:To reduce the time and the cost necessary for mounting by forming, on the surfaces of electrode terminals, recessed parts becoming deep gradually from the outer periphery toward the central part, and forming the central part by using metal whose melting point is lower than the outer periphery. CONSTITUTION:A plurality of bumps 2 are formed on a semiconductor element 1, and a plurality of electrode terminals 5 are formed on a board 3 so as to correspond with the bumps 2 on the element 1. On the surfaces of the terminals 5, recessed parts 4 accepting at least the tip parts of the bumps 2 are formed so as to become deep gradually from the outer periphery toward the central part. The central part 5a is formed by using metal whose melting point is lower than the metal forming the outer peripheral part 5b. Hence, the bumps 2 can be highly precisely aligned with the terminals 5 only by pressing the element 1 against the board 3 after rough alignment. Further, when the low melting point metal of the center parts 5a of the recessed parts 4 is melted, the bumps 2 on the element 1 are brought into the center parts 5a of the terminals 5 by the effect of surface tension. Thereby the time and the cost necessary for mounting can be reduced.

     CONSTITUTION: When row direction driving circuit X 1  and column direction driving circuit Y 1  are selected, -E is applied to conductor A 1 , and meanwhile, conductor B 1  is released. As a result, -E is applied to needle electrode S 11 . At this time, if Y 2  is not selected, half-selection potential -E/2 is give to needle electrode S 12 . Consequently, since the potential difference between electrode S 11  and adjacent S 12  becomes -E/2, the leak between electrodes is prevented from being generated. At this time, since X 2  is not selected, the half-selection potential is applied to only electrodes adjacent to needle electrode S 11  which is in a driving state, and power is not supplied to electrode groups S 21 , S 22 ...connected to conductor A 2  which is arranged at a distance from electrode S 11 , so that this system may be economical.
