Title: Terminating end crack preventive method in arc welding
Inventor: SHIMANUKI SHIZUKA
IPC: B23K9/00
Filed: 1979-02-13
Abstract: PURPOSE: To prevent terminating end crack by causing compressive strain in the terminating end due to arc heat strain difference, by welding and securing two end tabs differing in coefficient of thermal expansion to the terminating end of base metal in specified configuration.  
     CONSTITUTION: When an arc passes through the border line of steel plate terminating end tab plate, tear stress occurs in the direction vertical to weld line due to rotary deformation, which is concentrated in said border line to initiate crack in the terminating end. Therefore, the terminating end crack may be prevented by transforming this tear force into compressive force. Accordingly, materials 2, 1 of which coefficient of thermal expansion is equal to or larger than that of steel plate to be welded 3 are used in the end tabs. At this time, the material 1 is welded and secured to the material 3, while the material 2 is tack-welded to the material 1. The material 1 enters the inside of the material 2, and the extension of weld line 4 is positioned in the center of the material 1. In this setting, as advancing to the terminal end part of the arc, the material 1 swells larger than the material 3 until the clearance to the material 2 becomes null. Thereafter, a compressive stress acts on the material 1.

Title: Hot rolling process
Inventor: OOSONO RIYUUICHI
IPC: B21B37/00
Filed: 1978-02-10
Abstract: PURPOSE:To provide precise thickness plate steel, the steel plate is hot rolled in the final roll mill under the controlled temperature range in which steel deformation resistant is substantially constant. CONSTITUTION:When the crude rolling mill 1 completes crude rolling of the rolling material 4, a material temperature is measured by the thermometer 5 and transmitted to the calculator 6. The calculator 6 makes calculation, by using the measured temperature and the material 4 rolling schedule, a speed of the table 3b and a flow rate of the cooling spray 7 so that final rolling temperature is made to a specified temperature, that is, about A3 modification temperature. The calculated value of the table 3b speed is transmitted to the table motor speed control system 8, which controls table motor rotation to regulate the table 3b speed. The calculated value of the spray 7 flow rate is transmitted to the flow control valve 9, which controls cooling water amount of the spray 7 by adjusting valve opening. Thus, these means control the final rolling temperature of the material 4 to near A3 modification point to minimize diformation resistance variations.

Abstract: PURPOSE: To provide the titled polymer body easily by a method wherein fibers of appropriate diameters are aligned in a container, a monomer is poured into the container and polymerized in situ, then the polymer body is cut and only the fibers are removed by melting.  
     CONSTITUTION: The fibers (e.g., water-soluble polyvinil alcohol fibers) 3 are placed in the container 4, the monomer (e.g., methyl methacrylate) is poured into the container 4 and polymerized and solidified in situ. The resulting polymer body 7 is cut or cut off in such a shape that both ends of the fibers are located at the opposite surfaces of the body, thereby obtaining a semifinished product. The semifinished product is treated with a solution which dissolves the fibers but does not dissolve the polymer (e.g. water or an aqueous 0.9% solution of sodium chloride), thereby removing only the fibers by melting. Accordingly, the semifinished polymer product having the minute through-holes is obtained.
