Title: Resin composition for sliding material
Inventor: FUJII YOSHIKATSU
IPC: C08L61/04
Filed: 1979-10-25
Abstract: PURPOSE: To provide a resin compsn. for sliding materials, in which friction coefficient and wearing properties in an atmosphere under vacuum or high temperature conditions, are improved, by a method wherein hydrous graphite is added to a resin for a sliding material.  
     CONSTITUTION: Graphite is treated with an acid to obtain hydrous graphite. 5W 50wt% of the hydrous graphite is mixed with a resin compsn. for a sliding material. The hydrous graphite can be prepared, e.g., by treating natural flaky graphite with a conc. sulfuric acid-conc. nitric acid mixed, washing the resulting graphite with water, dehydrating the graphite, and, if necessary, neutralizing an excess of the acid or the acid adsorbed on the surface of the graphite with an e.g. soln. of ammonium hydroxide, and then drying the graphite at a temp. of 150W200°C.  When the added amount of the hydrous graphite is less than 5wt%, the effect of the addition of the graphite is low and the variability of characteristics will be increased. When the amount of the graphite is more than 50wt%, the miscibility and the moldability of the mixed material are remarkably lowered and the strength of the material is reduced.

IPC: C25C7/06
Filed: 1986-06-13
Abstract: PURPOSE:To keep a copper electrolytic soln. in an electrolytic cell at a temp. in a set temp. range and to increase a covering rate by feeding the electrolytic soln. to the cell through a heat exchanger so as to properly cool or heat the soln. according to the temp. CONSTITUTION:When copper is electrolyzed in an electrolytic cell covered to prevent the release of heat from the surface of an electrolytic soln., a copper electrolytic soln. is sent to a head tank through a heat exchanger 2.

Abstract: PURPOSE:To facilitate a ball bonding with an aluminum wire by flowing a current through a metallic wire forming a ball, heating and melting a ball forming part with an arc in this state and forming the ball having a metallic gloss. CONSTITUTION:An AC pulse arc 15 is, for example, generated between W electrodes 8A and 8B containing Toria (trade name) by changeover switches 7A-7D. A fine metallic wire 1 made of aluminum or aluminum alloy is inserted in the length necessary to form a ball 2 into an arc 15 and is molten. At this time arc 15 is covered with inert gas, e.g., Ar or the like supplied from a nozzle 9, and a desired current (0.1-100mA) is flowed through a resistor 11 from the arc 15 toward the wire 1 to a cathode. The diameter of the ball 2 is controlled by the current value and the feed amount of the wire 1. In this manner a ball capable of heat press-bonding can be formed to the aluminum wire which is apt to be oxidized.

As a result, the thermion emitting temperature is lowered to 1750 deg.K (lanthan hexaboride), and moreover, a tungsten carbide layer (W2C) is formed making the activation process unnecessary. And since the lanthan hexaboride is impregneted in the high melting point of metal sintered bodies 13, thermion emitting bodies 19 of a good adhesive property can be obtained.
