Title: Forging method for sintered block of tungsten or molybdenum
Inventor: TAKAHASHI TSUTAE
IPC: B22F3/17
Filed: 1980-11-18
Abstract: PURPOSE: To prevent the oxidation loss of a sintered block of tungsten or molybdenum without forming an inert atmosphere in a heating furnace by containing said block in a tightly closed case by way of a heat insulating material and heating the entire part thereof then forging the same.  
     CONSTITUTION: A box of, for example, stainless steel or mild steel is used for a tightly closed case, and a heat resistant metallic material which does not react with a sintered block of W or Mo. at heating temps., for example, powder of alumina, is packed as a heat insulating material in the space between the inside wall of the tightly closed case and the sintered block contained therein. After  the entire part is heated to prescribed temps. in a heating furnace, the entire  part of the tightly closed case is forged. Since the free ends of the plate after  forging form the shape of, for example, a dipper, this is prevented by placing  dummy materials consisting of a metallic material which does not react with W  or Mo at the temp. during heating or forging at both ends of the sintered block  in the positions faced to both end parts of the tightly closed case.

Title: Recording or reproducing device
Inventor: ITANI TAKASHI
IPC: G11B5/024
Filed: 1982-09-17
Abstract: PURPOSE:To perform erasure wider than a recording track by supplying an erasure signal to a magnetic head at a selected head position among positions set by the transfer of plural steps. CONSTITUTION:When the ''A<B'' output of a comparing circuit 114 rises to a high level, a control circuit 116 reverses a motor 2. Consequently, an U/D counter 113 enters into down counting mode and when it generates an output 3n, the ''A=B'' output of the comparing circuit 114 goes up to the high level again, so the heat 3 is set at a position Hn, where the erasure for the portion of one turn is carried out securely. At the same time, the counted value of a counter 123 is set to 2. After completion of said operation, when a timer circuit 121 has finished clocking a time (t), an U/D counter 109 further counts down by one and generates an output (3n-1). Consequently, the head 3 is set at a position H''n-1, where erasure for the portion of one turn is carried out again.

Abstract: PURPOSE: To improve detection accuracy and reliability by varying greatly a Hall voltage by controlling control currents of several Hall elements and then by connecting them so that the polarity of an output voltage will change by turns in sequence.  
     CONSTITUTION: As number wheel 11 turns, magnet 13 fixed eccentrically to the wheel turns to allow Hall elements, e.g. 12a and 12b corresponding to display numbers to oppose to N and S poles of magnet 13. At this time, Hall voltage E 1  proportional to control current IC 1  is induced across element 12a and voltage E 2  proportional to current IC 2  is similarly developed across element 12b. In this case, currents IC 1  and IC 2  differ in polarity and voltages E 1  and E 2  have the same polarity in the positive direction; and a Hall voltage corresponding to one of display number is equivalent to the sum of both voltages and detected via amplifier 14. Next, when magnet 13 advances by one step, the polarity of the magnet opposing to element 12b changes and the Hall voltages has the same polarity in the negative direction.

Filed: 1994-06-22
Abstract: PURPOSE: To permit an assembly comprising an arm, a floating box, and a projector to instantaneously rock and retreat in a collision with an object and to restore to its first angular position by providing a torsion spring which restores the assembly to an angular balanced position. CONSTITUTION: An assembly, which comprises an arm, a floating box, and a projector, is positioned by a support 6 and a locknut 8 within a pond containing radioactive materials, so that the projector inside the floating box is at an interval of about 120 degrees to the periphery of a nuclear reactor. If during various operations a certain robot or device collides against one of the assemblies and the assembly moves from an angular position where it is originally placed, a coil spring 17 placed about a rotation axis 4 and around a turning rod 11 restores the assembly to its initial angular position since the angular position of the directable support 6 is held locked by the locknut 8. Also, such free oscillating retreat of the assembly reduces impact caused by collision with an object and does not hinder other devices moving inside the pond.
