Title: Al alloy for fin of heat exchanger made of al
Inventor: ISHIKAWA KAZUNORI
IPC: C22C21/12
Filed: 1983-07-07
Abstract: PURPOSE:To obtain an Al alloy for the fins of a heat exchanger made of Al having improved heat conductivity without deteriorating the buckling resistance by restricting the total amount of Si and Fe in an Al-Cu-(Si+Fe) alloy and adding Mg and/or Zr. CONSTITUTION:This Al alloy for the fins of a heat exchanger consists of, by weight, 0.05-0.20% Cu, 0.3-0.6% Fe+Si, 0.1-0.5% Mg and/or 0.01-0.3% Zr and the balance Al with inevitable impurities. Reduction in the heat conductivity of the Al alloy is prevented by restricting the total amount of Fe and Si as impurities, and the buckling resistance is improved by adding Mg and/or Zr. The heat radiating effect of a heat exchanger can be improved by using the Al alloy, so the heat exchanger can be made small in size and light in weight.

Abstract: PURPOSE: To avoid an excessive increase in local voltage in a high temperature superconductor, that is, local heating of the high-temperature superconductor. CONSTITUTION: A hollow cylinder SL of a high-temperature superconductor 6 is covered with a conductive silver layer E1 having a thickness of 1 μm.

Filed: 1978-10-09
Abstract: PURPOSE: To accelerate the response performance as well as to increase the durability by inserting the hot wire strand containing the heat contact into the thick and large-caliber metal protective tube with its one end closed and then filling up the insulating agent.  
     CONSTITUTION: Hot wire strand 2 containing heat contact 2a is inserted along with filling tube 8 into thick and large-diameter metal protective tube 1 one end of which is closed. Then insulating agent 7 (such as MgO, etc.) is supplied from the upper part of tube 8 while giving vibration to tube 1 and lifting up tube 8. Thus strand 2 is positioned within tube 1 and at the same time filled up evenly with insulating agent 7. After filling agent 7, opening part 9 of tube 7 is sealed up via the resin or the like along with the diameter reduction process given. Thus the deterioration of the strand can be prevented due to no air existing within tube 1. As a result, the response performance can be accelerated by 5W8 times as much as conventional, at the same time increasing the durability owing to the increased outer diameter along with the facilitated manufacture.

Title: Tape winder
Inventor: NAKAO TOSHIAKI
IPC: H01B13/08
Filed: 1983-07-11
Abstract: PURPOSE:To improve work efficiency by fixing a filament vibration control guide brought into contact with the shroter sides of a filament rectangular in section to amplitude control means following the vibrating direction of the filament. CONSTITUTION:In case of winding tapes 2, 2' round a filament 1 with a tape winder 1, the winding speed of the tapes 2, 2' is different between the case where the tapes 2, 2' go along the shorter sides of the filament 1 and the case where they go along the longer sides thereof. If lateral guides 30, 30' are fixed with the tapes along the longer sides, that is, in the case of the higher winding speed, the tension of the tapes 2, 2' is increased remarkably, so that the tapes 2, 2' are apt to break. Therefore, the lateral guides 30, 30' are fixed to amplitude control means 34, 34', whereby when the winding speed of the tapes 2, 2' is increased to enhance tension, fluid cylinders 30, 30' are expanded and contracted corresponding to the tape tension to absorb the tnesion and prevent breakage of the tapes 2, 2'. Thus, the winding speed of a tape can be increased to improve work efficiency.

Abstract: PURPOSE:To make uniform the laser beam radiated on the sintered material surface, by making similar the shape of the convex mirror of the laser unit to the sectional shape of the sintered material, when the surface sintering is made for gears. CONSTITUTION:Along the light axis of CO2 gas laser 1 excited with glow discharge, the concave mirror 4 providing the flat mirror 2a, convex mirror 2c and through- hole 6 is placed, and the sintered material 5 is inserted in the through-hole 6. With this constitution, the shape of the convex mirror 2c is made similar to that of the cross section of the sintered material 5, that is, if the shape of the sintered material 5, is an equilateral triangle, the shape of the convex mirror 2c is also that. Thus, the ring laser beam in triangle shape 3c emitted from the surrounding of the convex mirror 2c is reflected on the concave mirror 4 and is collected on the point P2 of the sintered material 5 as the beam 3d. Thus, in the width l2 of the sintered material 5, the laser beam energy per unit area is made uniform and excellent sintering can be made.
