Title: Production of composite metal wire blank material
Inventor: KAWAGUCHI SEIICHI
IPC: B21C23/00
Filed: 1979-11-21
Abstract: PURPOSE: To easily obtain a composite metal wire blank material through hot extruding by closing a core material into the through-hole or bottomed hole of a billet center by means of a plug.  
     CONSTITUTION: A through-hole 2 or bottomed hole 2' is pierced at the center of a billet of a metal or alloy. Next, a core material 3 of a metal or alloy different from that of the billet 1 and of a diameter approximately the same as the hole diameter is inserted or the molten metal or alloy different from that of the billet 1 is injected into the hole. Thence, an external screw 5 comprising a material having deformation resistance and m.p. identical or resembling to those of the billet 1 is screwed into the internal screw 4 engraved on the inside circumferential surface of the opening end part of the through-hole 2 or bottomed hole 2', whereby the hole is closed. After this, this composite billet 6 is extruded hot to a composite metal wire blank material. The reasons for using the material deformation resistance and m.p. identical or resembling to those of the billet 1 for the external screw 5 lie in that when the core material 3 is lower in m.p. than the billet 1 it does not melt out and that even if there is a difference in deformation resistance between the core material 3 and the billet 1 there is no place for the core material 3 to move during working and the core material is deformed and extruded simultaneously with the billet 1.

Title: Mounting method of packaged ic and mounting board
Inventor: OTSUKA TETSUYA
IPC: H05K3/34
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To avoid a solder bridge, even if a packaged IC is soldered to a printed wiring board by reflow soldering. SOLUTION: Solder balls are arranged in rows along the circumference of the bottom plane of a CSP-type IC 10. A printed wiring board 20 is warped in the warping direction A-A at reflow heating. The CSP-type IC 10 is put on the printed wiring board 20 to have the arrangement directions of the solder balls inclined from the warping direction A-A and soldered by reflow soldering. In this way, since the CPS-type IC 10 is mounted in an inclined attitude, when the printed wiring board 20 is warped, the solder balls in the inclined directions are adjacent to each other, and distances between the adjacent solder balls are increased so that solder bridges can be avoided.

Title: Pulse generating circuit
Inventor: SHIMANO AKIO
IPC: H03K3/354
Filed: 1985-07-08
Abstract: PURPOSE:To attain start of pulse oscillation only with application of a power supply even when variation exists in characteristics between FETs by providing an active load field effect transistor (FETs) and the 1st resistor connected in parallel. CONSTITUTION:A couple of inverters comprising the active load FETs 13, 14 connected in parallel and a FET using the 1st resistors 19, 20 as loads a couple of capacitors 15, 16 connecting mutulaly input and output terminals of the inverters, and the 2nd resistors 17, 18 connected between the input terminal of each inverter and a constant potential are provided. Since the current saturation characteristic of the load of the inverters slows down by the 1st resistors 19, 20, the input input voltage range having >=1 voltage gain is widened. Thus, even when variation exists in the characteristic of each FET, positive feedback is applied by the application of power supply only and the pulse oscillation is started automatically.

Title: Video image stabilizing device
Inventor: YONEDA YUTAKA
IPC: H04N5/66
Filed: 1992-06-11
Abstract: PURPOSE:To suppress disturbance of a picture such as occurrence of unsynchronization pattern flow or noise due to a fault of a state of a video signal by including a means discriminating the normality of the state of the video signal and a means controlling application/non-application of the video signal to a video display device according to the discrimination. CONSTITUTION:A state of a video signal is discriminated at first by a means discriminating the normality, and its result is inputted to a means 7 controlling application/non-application of the video signal. When the state is discriminated to be normal, the means 7 writes a video signal to a video display device 4. When discriminated to be abnormal, the means 7 controlling application/non- application of the video signal to the video display device 4 interrupts tentatively the write to the device 4 and the write to the device 4 is restarted after the state of the video signal is restored. Since the device 7 has an after-image characteristic, even while the application of the video signal is interrupted, the display corresponding to the video signal having been applied so far is maintained. Thus, the disturbance in the video image is prevented.

Filed: 1978-12-07
Abstract: PURPOSE: To make it possible to transfer a large quantity of heat with a small temperature difference by tightly securing to the inner wall of the pipe a metal net wick having its surface formed with fine ruggedness with deposited metal.  
     CONSTITUTION: Burnt deposit of copper or a copper alloy can be effected on the surface of a copper or copper alloy wire gauze of, for example, 50W200 meshes, and numerous fine whisker-like protuberances can be provided on said surface by subjecting said wire gauze to an electrolytic treatment at a relatively high current density in a low-concentration electrolyte of sulfuric acid or copper sulfate without causing liquid turbulence. By using the thus obtained wire gauze as the wick for a heat pipe, it is possible to actually bring the contact angle of the operating fluid close to zero and to increase the capillary force while keeping the pressure loss at the substantially same level as in the case of ordinary wire gauze.

Title: Wave detecting circuit
Inventor: IMAIZUMI HIDEO
IPC: H04N5/60
Filed: 1988-06-20
Abstract: PURPOSE:To prevent the generation of buzzing noise by setting a correction filter at the preceding stage of a PLL circuit which locks the video IF signal to correct the Nyquist strobe and detecting the sound signal by means of the output signal of the PLL circuit that receives no influence of the phase modulation. CONSTITUTION:The output signal of a tuner 7 is applied to an SAM filter 8 and amplified by a video IF amplifying circuit 9. This amplified signal is transmitted through a correction filter 10 and applied to a phase comparator 14. The center frequency of the filter 10 is set so as to secure the characteristics exactly adverse to the Nyquist strobe. Thus the side bands f1-f4 of the video IF signal applied to the comparator 14 have the flat levels. As a result, the phase of the oscillation output signal of a VCO 12 is locked by the video IF signal received from the outside. Therefore a sound signal free from the buzzing noise can be obtained by detecting the voice IF signal by means of the output signal of a PLL circuit.
