Then said sintered body is removed from the jig, washed by a solvent and the remaining metal paste 2 is washed away. A conductive part only whereon metal is helically baked is left on the outer circumferential surface of the sintered body. Subsequently, outer electrodes 7 and 8 are attached to both end parts of the conductive part, the outer circumferential surface of the sintered body 1 is molded by resin 9, and an inductor 10 is formed. Consequently, the use of cutting tools is unnecessitated, and the reduction in cost of production can be achieved.

Patent JP-H02250696-A (JP)
Title: Electromagnetic driver
Inventor: UCHIYAMA HIDEKAZU
IPC: H02K33/00
Filed: 1989-03-22
Abstract: PURPOSE:To produce high output by arranging an electromagnet producing a field for repelling a permanent magnet at a position, facing with the permanent magnet, of a cylinder to be fitted linear reciprocally with a piston then exciting the electromagnet within a range where the crank angle varies from the top dead point of piston to a point 9 deg. behind the top dead point. CONSTITUTION:An electromagnet 4 is excited with the lowering stroke timing of a piston 2 which is subjected to repelling force and pushed downward thus rotating a crankshaft 8. The electromagnet 4 is excited only in the range of 0 deg. crank angle(top dead point) to 90 deg. crank angle (a point 90 deg. behind the top dead point) where shaft torque T is outputted effectively. Since power conduction time of an exciting coil 4b can be shortened considerably with scarce sacrifice of the output shaft torque T, power consumption can be reduced considerably. Furthermore, since heating of the exciting coil 4b can be suppressed, droppage of magnetic force due to heating can be avoided.

Title: Elimination of p-t-butylphenol
Inventor: WATANABE CHUZO
IPC: C07C37/86
Filed: 1993-03-08
Abstract: PURPOSE:To prevent p-t-butylphenol (PTBP) from solidification in condensers, valves and lines during clistillation by eliminating before hand the PTBP unreacted as a raw material and contained in the reaction liquor when the aimed PTBP derivative is distilled in its production. CONSTITUTION:After synthesizing an o-alkylated PTBP derivative, sodium hydroxide is added to the crude reaction liquor to eliminate the PTBP unreacted as a raw material through its dissolution in water. An o->=4C alkylated PTBP derivative is not soluble in water by NaOH addition and the PTBP unreacted is eliminated as an aqueous solution. With this elimination process, no distillation trouble for the reaction product separated due to distilling PTBP occurs, thereby facilitating the distilling operation for the PTBP derivative as well as simplifying the distillation equipment.
