Title: Manufacture of nb3sn superconductive wire rod
Inventor: TACHIKAWA KYOJI
IPC: C22C1/04
Filed: 1989-03-24
Abstract: PURPOSE:To form an easily workable Nb3Sn superconductive wire rod showing excellent superconductive characteristic in a strong magnetic field and having a large critical current capacity by adding titanium, zirconium or hafnium which are group-IVa elements to a tin base body having excellent workability. CONSTITUTION:In a pipe body of at least one of a thin alloy base body 1 containing one or more selected from titanium, zirconium or hafnium, a copper base body 3, and a niobium base body 2, the remaining base powders are charged, or in either pipe body of the tin alloy base body 1 or the niobium base body 2, the remaining base body powder are charged, and the processing to a determined form is carried out. Then, a diffusion heat treatment is carried out to form a Nb3Sn compound containing the group-IVa elements around the niobium base body 2. Thus, as a sufficient amount of tin can be supplied from the complex internal part by diffusion, a large amount of Nb3Sn compound phase can be obtained to form a wire rod having a large critical current capacity.

Title: Thickness regulator for coating film in applicator
Inventor: YAMANO TAKAO
IPC: B05C11/10
Filed: 1983-04-20
Abstract: PURPOSE:To maintain the thickness of a coating film constant, by adjusting a gap between a doctor knife and a belt-shaped film or the like to desired size by the action of an eccentric body eccentrically rotating round the same axis as that of the doctor knife. CONSTITUTION:When the thickness of a coating film to be applied onto an endless steel belt 11 as a belt-shaped workpiece is adjusted, the peripheral surface 23 of an outer wheel 22 attached to an eccentric body 15 is pressed onto both widthwise side edges 37 of the steel belt 11 with proper pressing power by an air cylinder 34. At the same time on the other hand, a gap 38 between the steel belt 11 and the edge part 14 of a doctor knife 13 is adjusted by the operation of a gap controlling handle. Hence, the steel belt 11 is let run to form a coating film on the belt 11 with the doctor knife 13. Since the peripheral surface 23 of the eccentric body 15 runs in contact with the outer surface of the belt 11 regardless of the vibration of the belt or the ununiform thickness of the belt itself, the gap 38 is held constant at all times.

Title: Production of aminonaphthols
Inventor: UCHINO NOBUHIKO
IPC: C07C67/00
Filed: 1988-03-25
Abstract: PURPOSE:To obtain the subject compound useful as an additive for photography, etc., in high yield, from hydroxynaphthalenehydroxamic acids, by using Lossen rearrangement reaction. CONSTITUTION:The aminonaphthols of formula II can be produced by Lossen rearrangement reaction of hydroxynaphthalenehydroxamic acids of formula I (W is benzene ring condensed to another benzene ring). The method is espe cially effective in synthesizing 2-amino-3-naphthol which is hardly synthesizable owing to the difficulty in the introduction of amino group into the 3-site of 2-naphthol. The process enables relatively free synthesis of various aminonaphthols to enable the control of the characteristics (e.g., photographic sensitivity and storage stability) of a photo-sensitive sensitizing dye, etc., over a wide range.
