Title: Impulse voltage superposing device
Inventor: AZUMA MASAHIRO
IPC: H02M9/06
Filed: 1985-04-18
Abstract: PURPOSE:To protect a facility apparatus by inserting a zinc oxide arrester element between an AC voltage generator and an impulse voltage generator, thereby smoothly testing in a short time. CONSTITUTION:An AC voltage generator 1 generates the prescribed AC voltage to an element 2 to be tested. An impulse voltage generator 3 superposes the impulse voltage on the AC voltage of the generator 1, and applies it to the element 2 to test the insulating characteristic. A separating gap 4 is provided to prevent the AC voltage from being applied to the generator 3. Further, the superposing phase is regulated by a phase regulator 5, and the generator 3 is energized by a trigger generator 6. In this case, a zinc oxide arrester element 7 is connected in series with one end of the gap 4. Thus, a current is limited by the series impedance of the element 7 when the gap 4 is flashed over so that an AC arc can be readily cut in the gap 4.

Title: Method for rolling tooth profile of spur gear by working while relieving residual strain
Inventor: SUGINO HIDEO
IPC: B21H5/00
Filed: 1983-05-12
Abstract: PURPOSE:To eliminate defect owing to a residual strain by heating the required part of a blank material for a spur gear to a specific temp., working axially the material by a boat-shaped tool and generating a tooth profile while relieving the residual strain. CONSTITUTION:A blank material 2 for a spur gear is heated from the outside circumference at the end face thereof toward the central part by a heater 1 and the material 2 is moved in an arrow 8 direction then the end face on the outside circumferential surface of the material 2 bites into the bow part of a boat- shaped tool 3. When the number of teeth is indexed and a switch of a motor is turned on, the tool 3 and the material 2 rotate. When the working ends, the temp. of the material 2 decreases during the working and therefore the material 2 is moved while the material is heated further by the heater 1 in an arrow 8' direction. The material 2 is removed from a center 5. Since stress remains in the material 2 on decreasing of the temp. during the working, the material is again heated to 600-650 deg.C and is removed from the machine. The material is placed as it is in a prescribed position and is released after the temp. of the material is restored to an ordinary temp.

Abstract: PURPOSE: To carry out precise cutting of a long member while transferring it at by a preset distance, by making a frame, on which the member is held, oscillate to the direction of transfer and reset to its original position for correcting the downward bending of the member.  
     CONSTITUTION: A long member 1 to be cut is put by its both sides between cylinders 23, 23 fitted to a double housing frame 14 and it transferred being driven by a saddle 5 on a roller conveyor 2. When the member 1 is moved not to collide with the rollers as the frame 14 rises, the head side pressure of a cylinder 26 is reduced, the pressure of an accumulator 34 resumes its original state, oil is supplied by means of a pump 39 to push a piston rod 27 to resume its starting position. This resets the position of the frame 14 against the saddle 5 by oscillating a lever 28 in the reverse direction, thus transferring the frame by the same distance as the saddle to cut the member 1 with an accurate precision.

Abstract: PURPOSE:To improve operability and measurement accuracy remarkably by a method wherein a work piece is put on a gimbal and made to approach a rotating glass disk, a beam of light is applied thereto, and the degree of flatness of a floating surface is measured from interference fringes generated by said beam. CONSTITUTION:A work piece 4 of a core slider used for a magnetic head is put on a work piece support 53 on a gimbal 50 having a gimbal support 70 which prevent an air current. This work piece 4 is made to approach a rotating glass disk 51 representing the degree of flatness, and a beam 72 of light is applied thereto from above. Then interference fringes are obtained on the floating surface of the work piece 4. From the size of slippage of a fringe pattern of the upper line 30, intermediate line 31 and upper line 32 of the fringes and the wavelength of the beam, the degree of flatness of the floating surface is calculated on the basis of a prescribed calculation formula. Therefore, the operability becomes very excellent, while reading can be implemented in a short time, and thus the degree of flatness can be measured with an accuracy of 0.01mum or below.
