Title: Production of superfine powder of high-melting-point carbide
Inventor: OGAWA TORU
IPC: C04B35/56
Filed: 1989-02-03
Abstract: PURPOSE:To easily produce the superfine powder of a high-melting-point carbide excellent in sinterability by hydrolyzing a transition-metal alkoxide in a suspension of carbon in alcohol under specified conditions, drying the formed gel, heating and then disintegrating the dry gel. CONSTITUTION:A carbon suspension, alcohol and a transition-metal alkoxide, alcohol and water are mixed, the pH of the mixture is controlled to a value close to the isoelectric point of the transition-metal oxide, and hydrolysis is carried out. The water is removed by heating, etc., to dry the product, and a metal oxide gel in which fine carbon grains are uniformly dispersed is obtained. The gel is heated (ordinarily at about 1250 deg.C) in vacuum or in an inert gas to obtain a granular carbide which is disintegrated for several minutes by an ultrasonic wave, etc., into fine powder. By this method, the superfine powder of a high-melting-point carbide such as ZrC, TiC and TaC having 4 about 1mu grain diameter is easily obtained.

Title: Manufacture of needle
Inventor: IIJIMA TETSUO
IPC: B23P13/00
Filed: 1988-02-08
Abstract: PURPOSE:To obtain the simple method for manufacturing needles in a wide application range by etching-treating a metal wire on which a deformed or broken part is formed, on the surface of an electrolytic liquid or in the electrolytic liquid. CONSTITUTION:After a metal wire 1 is inserted into a tube 3, a deformed or broken part 2 is formed on the metal wire 1, and then said wire 1 is etching- treated in an electrolytic liquid. Then, the wire is surely cut at the deformed or broken part 2. Since a formed needle projects by several mm from the top edge of an insulating tube 3' in the lower part, said needle can be easily taken out. The reason of the formation of the needle at the deformed or broken part 2 comes from the fact that this part is made thinner in comparison with the diameter of the original wire, and etching is completed faster, or the surface area of the etching-treated part is increased, and the etching rate is increased.

Abstract: PURPOSE:To detect a flaw accurately, by coating magnetic powder with synthetic resin  containing a fluorescent agent and coloring agent and thereafter, coating said powder  with a surface active agent by using a solution of the surface active agent in which  covered magnetic powder is dissolved moreover in a solvent not dissolving said synthetic resins. CONSTITUTION:Polyvinyl butyral resin is dissolved in an organic solvent and a fluorescent agent (9, 10-dianilinoanthracene etc.) is dissolved in this solution and then, a magnetic powder having 8-12mu mean grain diameter is kneaded with a dispersion of a  coloring agent (pigments such as titanium white, red oxide, graphite). Thereafter, the  solvent is evaporated by heating and a resin coated magnetic powder A is obtained by  crushing said solid matter. Next, 100pts. powder A and 40pts. solvent not dissolving  the resin, are add to a solution of 4pts. nonionic or anionic surface active agent. Said solution is kneaded and is heated and then, the solvent is removed. Thereafter, obtained solid matter is crushed and is sieved and then, the magnetic powder for flaw inspection having 10-15mu diameter is obtained. Accordingly, inspection accuracy is high and the  secular change of the magnetic powder is lessened because said powder is dispersed in water or solvent thoroughly and dispersion liquid is stuck on a defective part to be  inspected only and then, the coloring agent and fluorescent agent are not separated  from the magnetic powder.
