Title: Regenerating method for ion exchanger
Inventor: UNO YASUMITSU
IPC: B01J47/12
Filed: 1980-07-01
Abstract: PURPOSE: To regenerate an ion exchanger efficiently without using chemicals by joining both ends of cation and anion exchangers and treating electrochemically after passing through between electrodes.  
     CONSTITUTION: The end of an anion exchange belt 2 and that of a cation exchange belt 3 ion exchanged by treated water are joined and passed through between electrodes 7, 6 to partition electrolytic solution, and voltage is applied between the electrodes 7, 6. Thus, ions that ion exchanged the cation exchange belt 3 migrate to an anion chamber 9, and ios that ion exchanged the anion exchange belt 2 migrate to the cation chamber 10. H +  ions formed on the anode 7 migrate toward the cathode and ion exchange the cation exchange belt 3 to make it H type. OH -  ions formed on the cathode 6 migrate toward the anode 7 and ion exchange the anion exchange belt 2 to make it OH type. By this way, the ion exchanger is regenerated continuously.

Title: Manufacture of schottky barrier diode
Inventor: NISHIOKA TAIJO
IPC: H01L29/872
Filed: 1985-04-26
Abstract: PURPOSE:To suppress a voltage fluctuation and keep excellent heat resistant property even if the area is reduced by a method wherein, after SiO2 of a bird beak part is removed by etching using a photoresist mask, a Schottky junction is formed. CONSTITUTION:Photoresist patterns 5 are formed on bird beak parts 11 of an SBD formation region on an Si substrate 2 by photolithography. SiO2 of the bird beak part 11 is removed by etching utilizing the photoresist pattern 5 as a mask. The method of etching the bird beak 11 may be an anisotropic dry etching or a wet etching with a mixture solution of hydrogen fluoride and ammonium fluoride. The area of a contact hole 10 is increased by the etching of the bird beaks 11 and this area is determined by the photoresist patterns 5 whose areas are very uniform. Therefore, variation of the areas especially within a wafer surface and between wafers can be minimized.

Title: Method for welding spiral pipe
Inventor: OGATA YOSHINORI
IPC: B23K9/032
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To obtain a method for manufacturing a spiral pipe by successively welding both side edge parts by a submarged arc welding method as forming a steel strip into a spiral shape. SOLUTION: Welding is executed as feeding a wire which is not energized toward a molten pool 7 from the side of the opposite direction to the advancing direction of welding. Thus, the solidifying speed of weld metal is accelerated and the shape of the recessed part which is formed in the middle part of bead is mitigated. In the welding of the spiral pipe, especially, the recessed part of the inside bead is reduced and it is effective to the suppression of undercut, so the labor and time required to repair products are drastically savable. And, as a result, the speedup of welding speed is expectable.

Abstract: PURPOSE:To contrive vaporization of oil in exhaust gas by increasing an exhaust gas temperature and to reduce exhaust smoke, by providing a catalyzar on an inner wall more upstream than an exhaust pipe to be connected with and directly after the exhaust pipe. CONSTITUTION:A catalyzer 7 formed by letting a metallic particulate having character of an oxidized catalyzer carry extending over a whole length of the internal circumference of a cylindrically molded ceramic carrier is provided in an exhaust pipe 5 directly after an exhaust opening 3 which is more upstream of an exhaust pipe 6a forming an exhaust course than the exhaust opening 3 formed on a wall of a cylinder (a). This catalyzer 7 is held by fitting it in a concave notched part 8 formed by notching the exhaust pipe 5 extending from an upstream to a downstream sides of the same. A temperature of exhaust gas is increased and oil contained in the exhaust gas can be vaporized as the exhaust gas is heated by chemical reaction when the exhaust gas is touched to the catalyzer 7. The oil, therefore, can be prevented from remaining and dispersing into the exhaust pipe 6a, and white smoke in the exhaust gas can be prevented.

IPC: C07D279/28
Filed: 1994-04-05
Abstract: PURPOSE:To obtain the title curative which is stable at about normal temp. but is excellent in latent curing properties, curing rapidly at high temps., by introducing specific groups into cyanoguanidine. CONSTITUTION:This curative is represented by formula I [R is a group of formula II (n is 1-8), III, IV, V, VI, VII, etc., (in each formula, X is a group of formula VIII)]. Cyanoguanidine has been well-known as the curative for an epoxy resin, and substd. cyanoguanidines have also been known to be useful for the purpose.'
