Title: Production process for fatty acid monoalcanolamine amide
Inventor: KADO KAZUHIRO
IPC: C07C233/20
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To obtain a fatty acid mono-alkanolamine amide that includes considerably low levels of an unreacted raw material and ester amide, has good color tone with reduced smell by allowing a fatty acid methyl ester to react with a specific monoalkanolamine in the presence of an alkali catalyst. SOLUTION: The condensation reaction between a fatty acid methyl ester of formula I [R is a (OH-substituted) 5-21C alkyl, or an alkenyl] and a monoalkanolamine of formula II (X is H or methyl) is carried out in the presence of an alkali catalyst, then water is added to the reaction mixture, which is heated, after completion of the reaction, and the water is removed under reduced pressure to give the objective compound useful as an auxiliary for detergent and as an additive. In a preferred embodiment, water is added to the reaction mixture after completion of the condensation reaction, stirred at 80-180 deg.C for 5-60 minutes and an excessive amount of water is distilled off under a reduced pressure. The water is added, preferably in an amount of 0.2-30.0 wt.% based on the theoretical yield of the fatty acid monoalkanol amide.

Title: Manufacture of saddle-like deflecting coil
Inventor: KITAMURA KATSUYUKI
IPC: H01J29/76
Filed: 1982-12-24
Abstract: PURPOSE:To reduce suction force exerted among electric wires so as to maintain the saddle-like shape of a deflecting coil stably by simultaneously winding a number of electric wires to be fused to make the saddle-like coil before the electric wires are fused by feeding currents of reverse directions in the electric wire groups. CONSTITUTION:In making a saddle-like deflecting coil 11 used as a horizontally deflecting coil for a television receiver, a number of electric wires to be fused are simultaneously wound into a saddle-like shape having a window portion 12 and a peripheral portion 13. After that, currents are fed to the thus formed body in such a manner that the direction of a current flowing in half of the electric wires is reverse to that of a current flowing in the remaining half to produce Joule heat, thereby fusing the electric wires. As a result, the saddle-like shape can be stably maintained by decreasing suction force exerted among the electric wires during current feeding, thereby preventing any reduction in the performance of the saddle-like deflecting coil 11 which might be caused due to a deteriorated distribution of the winding and improving efficiency of making the coil 11.
