Patent JP-S614756-A (JP)
Title: Preparation of composite powder
Inventor: IWAMOTO TOYOZOU
IPC: D21H17/67
Filed: 1984-06-20
Abstract: PURPOSE:To obtain composite powders having excellent oil absorptivity and an excellent effect of inhibiting ink strike-through when used as a filler for paper, by grinding a mixture of a hydrated silicic acid and urea resin powders to reduce the bulk specific gravity below a specified value. CONSTITUTION:A hydrated silicic acid obtained by, for example, the neutralization of an alkali silicate with an acid, and urea resin powders are mixed preferably in a weight ratio of 4-47:1. This mixture is ground to reduce the bulk specific gravity to 0.18g/cc or less, giving aimed composite powders. An example of a typical grinding method is the use of a fluid-energy mill with a fluid pressure at the inlet nozzle of 5kg/cm<2> or higher. The decrease in oil absorptivity of a hydrated silicic acid when it is dipped in water and dried will be effectively inhibited by the incorporation of urea powders therein.

Title: High-frequency high voltage generator for arc welding
Inventor: KASHIMA TAKAYUKI
IPC: B23K9/073
Filed: 1984-06-20
Abstract: PURPOSE:To charge a condenser to a required voltage with a high-frequency transformer having small current capacity by operating a boosting transformer as a high-frequency transformer by a switch circuit, converting a high-frequency high voltage to DC and impressing said voltage to the condenser. CONSTITUTION:A DC high voltage generating circuit B is constituted of a high- frequency transformer 12, a switching circuit 11 which intermits periodically the primary current to the transformer 12 and a diode 13 for high voltage which is a current rectifying element to convert the high-frequency voltage induced in the secondary side of the transformer 12 to DC. The required voltage can be therefore charged to the condenser even if the current capacity of the transformer 12 is small when the high-frequency high voltage is rectified by the diode 13 and impressed to the condenser. The high-frequency oscillation current flows to the series circuit of the condenser, a discharge gap 10 and the primary side of a coupling coil 10 when the voltage of the condenser attains the discharge start voltage of the discharge gap 10. The high-frequency high voltage is then generated in the welding circuit to assist the arc start.

Title: Interlaced fiber sheet having natural unevenness and raised fiber
Inventor: SAITO YOSHIMITSU
IPC: D04H1/4274
Filed: 1995-04-14
Abstract: PURPOSE: To improve the shape-retainability, dimensional stability and washing resistance of nonwoven fabric made of vegetable fiber by applying a polymer processing treatment before or after the softening treatment of the fabric and giving irregular strain to the fabric by a flexing machine or a tumbler. CONSTITUTION: A web is produced by using vegetable fibers longer than a prescribed length. Nonwoven fabric is produced by interlacing the fiber of the web by a high-speed fluid jet. Usually the nonwoven fabric is subjected to softening treatment or rubbing treatment after a polymer processing treatment when the thickness or weight of the fabric is smaller than prescribed levels or without using the polymer processing treatment when the thickness or weight is larger than prescribed levels. The fiber bundles are loosened to loosen the interlace, flexibilize the fiber, form a twist, give a natural unevenness and shading irregularity and form raised fibers and fluffs. Polymer processing treatment is applied to improve the shape-retainability, dimensional stability, washing resistance, etc., of fabric free from polymer processing treatment.

Abstract: PURPOSE:To purify crude phenylhydrazine into a purified, almost colorless and transparent substance having improved color tone in purifying the crude phenylhydrazine after distilling away an extracting agent by the rectification or simple distillation, by the presence of hydroxide of an alkali metal or alkaline earth metal. CONSTITUTION:A salt of phenylhydrazine obtained by the diazotation reduction and hydrolysis of aniline is neutralized with an alkali and extracted with an organic solvent.
