Title: Diffusion treatment of steel material
Inventor: NAKAMURA MOTOHARU
IPC: C23C10/28
Filed: 1979-12-14
Abstract: PURPOSE:To subject the surface of a steel material to a diffusion treatment without removing scale previously by a method in which Al or/and Si with diffusion elements are given in a specific ratio to the amount of scale on the surface of a steel material, and on these Al or/and Si, etc., an antioxidant layer is formed and heated. CONSTITUTION:On the surface where scale composed mainly of FeO, etc., are present of a steel material, Al or/and Si powder are located first and then various diffusion elements, e.g., Cr, Zn, etc., are placed. Then, an antioxidant layer is formed on these diffusion elements and then heated in the air, whereby the diffusion elements are diffused over the surface of the steel material without the needs for the removal of scale in advance. The amounts of  Al or/and Si should meet the formula.

Title: Cord reel
Inventor: HIRAOKA MICHIO
IPC: B65H75/48
Filed: 1983-09-06
Abstract: PURPOSE:To automatically stop a power cord in an optional position and reduce the thickness of a cord reel, by utilizing the power cord as a part of a stopper mechanism. CONSTITUTION:When a power cord 21 is pulled out, a roller B25 is rotated and another roller A24 is also rotated to such a position, pulling a spring 26, that the cord can be pulled out. When the force pulling the power cord 21 is decreased in that state, the cord is put on the verge of being wound back by the force of a helical spring, but is pinched between the rollers A24, B25 and automatically stopped in the pulled-out position by the friction between the roller A24 and the cord and the restoring force of the spring 26 provided between the roller B25 and a case A22. To wind back the power cord 21, the lever of the roller A24 is tilted down to draw the spring 26 to eliminate the pinching action of the roller. As a result, the cord 21 is wound back on a reel 20 by the helical spring.
