Title: Producing device for welding rod
Inventor: UEDA MITSUHIKO
IPC: B22D18/06
Filed: 1981-05-11
Abstract: PURPOSE:To produce welding rods easily from highly hard and difficult to forge materials by immersing a cartridge into molten metal constituting the welding rods and sucking it up with a vacuum. CONSTITUTION:A vacuum chamber 2 is evacuated by closing the 2nd valve 9, opening the 1st valve 3 and operating a vacuum pump 1. The 1st motor 13 is driven to rotate an arm pipe 7, thereby setting one cartridge 10 over molten metal 29. The 1st valve 3 is closed and the 2nd motor 21 is driven to immerse respective pipes 11 together with the cartridge 10 into molten metal 29. When the 2nd valve 9 is opened, the metal 29 is sucked up into the pipes 11. If the temp. of the metal 29 is high, its viscosity is small and long materials are obtained in the pipes 11. If the degree of vacuum is high, suction forces increase and long materials are obtained.

Title: Method for welding metal catalyst carrier
Inventor: NAKAMURA KATSUAKI
IPC: F01N3/28
Filed: 1988-03-25
Abstract: PURPOSE:To remarkably improve the welding strength by previously projecting a flat sheet at both end faces of a core part at the time of winding a corrugated sheet and the flat sheet, pressing and bending the projected part when an electrode is welded to the end face of the core part, and resistance-welding both sheets. CONSTITUTION:The width of the flat sheet 25 is made slightly larger than that of the corrugated sheet 23, and the flat sheet 25 is projected from the corrugated sheet 23 at both end faces of the core part 21 when the sheets are wound. The edge of the flat sheet 25 is successively bent immediately before winding to form bent part 27 on the inlet side and the bent part 29 on the outlet side. When the end face is then allowed to abut on the core part 21 of an electrode 35, the electrode 35 is pressed on the end face, and hence the bent part 27 on the inlet side as the projected part of the flat sheet 25 and the bent part 29 on the outlet side are surely bent toward the end face of the corrugated sheet 23 and resistance-welded.

Title: Drive circuit for switching type dc converter
Inventor: NOZAWA SHIYUNICHI
IPC: H02M3/335
Filed: 1982-04-30
Abstract: PURPOSE:To stabilize the operation of a converter by composing to automatically limit the current when a load is shortcircuited to a small value. CONSTITUTION:The terminal voltage of a condenser C4 becomes much smaller than the normal value in the state that a load is shortcircuited or in the near state, and the amplitude of a jumping voltage which is presented at a coil 12 can be suppressed by the voltage of a condenser C4 to a small amplitude. Accordingly, the voltage of the coil 13 can be reduced, and the slope of the waveform in the vicinity of zero crossing point can be very smooth. Thus, the voltage waveform at the point c, at which the waveform is differentiated, can be reduced in negative amplitude. In this manner, even if a pulse is applied to the point c since the voltage Vd from the point d is considerably larger than the voltage Ve at the initial zero crossing point of the jumping voltage, a comparator 6 does not operate. Therefore, the comparator 6 does not operate until the voltage Vd is reduced to the value near the Ve, with the result that the opening period of the switch 14 becomes much longer than the normal operation.

Title: Synchronous signal processor
Inventor: TAMAKI SHIGEHIRO
IPC: H04N5/04
Filed: 1988-03-26
Abstract: PURPOSE:To prevent the timing of an internal vertical synchronous signal from being advanced by fixed noise by substituting a horizontal interrupting signal generated from the horizontal synchronous signal of a video signal for an internal horizontal interrupting signal to which a system clock is frequency-divided and executing the initializing of a horizontal direction counter. CONSTITUTION:A means 10, which generates a horizontal interrupting inhibiting signal (h) to have a time width covering a period in which fixed noise is super imposed on a video signal, and a means 11, which switches a horizontal interrupting signal HE initializing a horizontal direction counter 3 to an internal horizontal interrupting signal HI obtained by decoding the count value of the horizontal direction counter 3 for the period in which the horizontal interrupting inhibiting signal (h), are provided. Since the switching means 11 uses the internal horizontal interrupting signal HI obtained by the flywheel action of the closed- loop-constituted horizontal direction counter 3 and a horizontal direction combinational circuit 4 for the period in which the fixed noise is superimposed, the instrumentation of a horizontal period is not disturbed by the fixed noise. Thus, the output timing of an internal vertical synchronous signal does not receive the effect of the fixed noise.

Filed: 1993-03-30
Abstract: PURPOSE:To obtain an address generating device which can handle a rational address like affine transformation, has a small circuit scale, and can be made fast by providing a specific mask means, a specific shift means, and an adding means. CONSTITUTION:An (x)-directional logical address and a (y)-directional logical address have 1-bit decimal parts. When they are converted into a physical address, the (x)-directional logical address is arranged at the low-order digits. A bit mask circuit 1 masks the digits of the decimal part and replaces them with 0. Then, the address to be placed at the high-order side is shifted to the right or left by the difference between the (n)-bit width of the low-order side and the 1-bit width of the decimal part. At this time, the address is padded with 0 from the high-order or low-order side. The address to be arranged on the low-order side, on the other hand, is shifted to the right by the 1-bit width of the decimal part. At this time, the address is padded with 0 from the high- order side. The logical addresses which are separated in the (x) direction and (y) direction are connected by an adder to generate an (m+n)-bit physical address.
