Title: Electrode wire for wire electric discharge machining and its manufacture
Inventor: SHIYOU HITOSHI
IPC: C23C22/24
Filed: 1985-06-14
Abstract: PURPOSE:To shorten the discharge gap thus to improve the machining speed and accuracy by placing brass wire containing specific weight of zinc into sulfuric acid aqueous solution containing specific quantity of chrome ions and sulfuric acid and applying coating of specific thickness through immersion or electrolysis. CONSTITUTION:When 100-1,000Angstrom  chrome oxide is coated during discharge, shortcircuit or cutting through welding are prevented while the effect of zinc in brass wire is never damaged. While in manufacturing method, if the quantity of chrome ions in aqueous solution for performing chrome acid processing is lower than 5g/l, chrome oxide will never adhere sufficiently while if it is higher than 100g/l, the liquid will be unstable to never adhere stably and if it is lower than 5g/l, it is not effective while if it is higher than 30g/l, brass wire will dissolve more. It is not so effective for such quantity of Zn in brass electrode wire as lower than 30% while it is hard to extend the wire for the quantity of Zn higher than 40%. When employing such wire, the discharge gap can be shortened to consume the spark discharge energy efficiently for fusing and removal of work resulting in improvement of the machining speed and the accuracy.

Title: Process for lining inside surface of pipe
Inventor: KARASAWA HIROSHI
IPC: B05D7/22
Filed: 1985-06-14
Abstract: PURPOSE:To execute lining of an inside surface of a pipe inexpensively without giving damage to the pipe by filling a lining material in the pipe between a preceding and recording pig, disposed in the pipe, allowing a pressure of pressurized liquid to act on a hind surface of the receding pig to move the preceding and recording pig to run integrally together with the lining material. CONSTITUTION:A lining material 4 (e.g. cement mortar mixed with an admixture for underwater concrete) is filled between preceding and receding pigs 2, 3 in a pipe 1, then the preceding and receding pig and the lining material are caused to run integrally by acting the pressure of pressurized fluid 6 such as water on the hind surface of the receding pig 3. Thus the inside surface of the pipe is lined with the lining material passed through the space between the receding pig and the inside surface of the pipe. By this method, necessary cost for driving the liquid is reduced even for a large-sized pipe to be lined, and noise is also reduced. Further, damages or breakages of pipes are prevented. Moreover, there is no fear for causing floating up of the pipe during work for lining even if the pipe is laid under water such as sea bed, etc.

Title: Disc-shaped body caused to fly by controlling gravitational acceleration
Inventor: MUKAI KUSUE
IPC: F03H99/00
Filed: 1981-08-20
Abstract: PURPOSE:To optionally cause a body to fly, by controlling the acceleration energy in the gravitational field of the earth and other planets. CONSTITUTION:Annular pulsing high-frequency magnetic fields 11 are produced around the electroconductive coil 3 of a flying body. Microwaves or millimeter waves generated by an electromagnetic wave oscillating unit in a motive power chamber 1 are emitted upwards from the open parts 4 of waveguides 5 to a parabolic outer part 2 centering the direction of the electroconductive coil 3. The electromagnetic waves are reflected on the concave surface of the parabolic outer part 2 so that the waves proceed downwards and pass through the pulsing high-frequency magnetic fields 11 halfway. The magnetic fields 11 and the electromagnetic waves have such frequency that the components of the magnetic fields and the magnetic field components of the electromagnetic waves resonate with each other or absorb each other. For that reason, the energy of the magnetic fields 11 is increased so that pulsing high-frequency resonant magnetic fields 12 are generated.

Filed: 1992-04-22
Abstract: PURPOSE:To carry a continued terminal regardless of size and interval of feeding hole for continued terminal by carrying the continued terminal by the friction of a driving pulley to the continued terminal. CONSTITUTION:The rotating shaft 52 of a driving pulley 50 is inclined at about 1 deg. from the right-angled direction to the feeding direction of a continued terminal. Thus, the contact point of the pulley 50 to a band carrier is approached to a protruding surface 44 as drive is progressed. The rotating shaft 62 of a dragging force giving pulley 60 is inclined at 5 deg. from the right-angled direction to the feeding direction of the continued terminal. Thus, the contact point of the pulley 60 to the band carrier is approached to the protruding surface 44 as drive is progressed, and the terminal is pushed to the protruding part 44 by the position of the pulley 60. The pressing forces of the pulleys 50, 60 are regulated by a mechanism 55 and a regulating knob. The continued terminal is carried along the protruding part 44 of a guide part 40, and can be cut in a determined dimension. Since the continued terminal is carried by the friction of the pulley 50 to the band carrier, thus, the carriage can be performed regardless of size and interval of feeding hole.
