Abstract: PURPOSE:To provide the pad for the skin which is soft and obviates the hooking and hit to the skin by superposing plural sheets of non-woven fabrics contg. thermoplastic fibers, ultrasonically sealing and melt cutting these fabrics to a wire shape and sealing the powder to be applied to the skin therein. CONSTITUTION:Fiber webs of 100% side-by-side type composite fibers consisting of two components of polypropylene and modified polypropylene are subjected to a waterflow slip treatment and two sheets of such webs are laminated. Talcum powder is sprayed by 2g each at 10cm interval and further, one sheet of the water-flow slip non-woven fabric is laminated thereon. The talcum powder is held mainly in the middle water-flow slip non-woven fabric. The laminate is inserted between a circular cylindrical ultrasonic horn and a cylindrical metallic die which is cylindrical and is formed with a cylindrical blade at one end in such a manner that the center of the talcum powder of the laminate comes to the center of the metallic mold. This laminate is cut to a circular shape and simultaneously, the peripheral edge is ultrasonically welded under ultrasonic conditions of 3kg pressurization and 0.4 second oscillation. Since the broad hardened part by the welding is not formed in the circumferential part of the pad for the skin, there is no hooking to the skin and this pad is particularly suitable for babies.

Title: Cylindrical thermal printing element
Inventor: NAKASAKI MASAHARU
IPC: B41J2/335
Filed: 1987-11-26
Abstract: PURPOSE:To prevent an increase in the internal temperature of a cylindrical base, and reduce the internal heat accumulation of the cylindrical base even during high-speed printing to improve printing quality by using a low cost cylindrical base having satisfactory printing quality even on recording paper with a significantly uneven surface and providing a cooling means in the hollow part of the cylindrical base. CONSTITUTION:Heat generated in a resistant thermal element 2 is transmitted to a recording paper 7 side through a protective film to increase the temperature of the predetermined part of the recording paper 7 and thereby obtain printing dots. The heat generated in the resistant thermal element 2 not only runs to the recording paper 7 side but also conducts through wiring electrodes 3a, 3b provided on the surface of a base 1 and scatters, or conducts to near a point A inside the base 1. The heat conducted to near the point A transmits to near a point B, reaching a metal rod 5 inserted closely into the hollow part of the base 1 through the neighborhood of the point B. For this reason, even when printing is performed at high speed, ink run or print deformation which is generated by an increase in the heat accumulation near the point A in the base 1 is minimized.
