Title: Absorptive article
Inventor: SHIMIZU JOJI
IPC: A61L15/28
Filed: 2001-05-07
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility that a tacky adhesive layer and rear surface layer partly remain on underwear when the rear surface layer 12 is peeled after being secured to the underwear across the tacky adhesive layer as the surface strength and rupture strength (interpaper strength) in a thickness direction of the rear surface layer 12 of an absorptive article are degraded when the rear surface layer 12 is generally enhanced in waiter solubility. SOLUTION: The absorptive article 1 has the water-soluble rear surface layer 12, a liquid permeable front surface layer 10 and an absorption layer 11 held between the rear surface layer 12 and the front surface layer 10. The rear surface layer 12 is formed of a fiber sheet containing water-dispersible fibers and water-insoluble carboxymethylcellulose. The rate of the etherification (D.S) of the water-insoluble carboxymethylcellulose is 0.3 to 0.6 and the hydrogen of >=95% carboxylic acid is substituted with metal in the water-insoluble carboxymethylcellulose. The rear surface layer 12 is excellent in water solubility, has the high surface strength and the rupture strength in the thickness direction and hardly allows part of the tacky adhesive layer and the rear surface layer to remain at the underwear when peeling the layer from the underwear.

Title: Method of manufacturing electrode wire for wire electric discharge machining
Inventor: KURODA HIROMITSU
IPC: B23H7/08
Filed: 2001-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrode wire for wire electric discharge machining that can produce a Cu-Zn alloy coating layer having a desirable zinc concentration without an increase in manufacturing cost and excels in wiredrawing workability. SOLUTION: A core 1 of copper or copper alloy is coated with a zinc layer over the surface and next coated with a Cu-Zn layer over the surface of the zinc layer to form a composite wire rod. The composite wire rod is subjected to heat treatment in a heating furnace to diffuse zinc in the zinc layer into the Cu-Zn layer and thus form the Cu-Zn alloy layer 5. Wiredrawing in the phase of the composite wire rod, which wiredraws mainly the portion of the Cu-Zn layer with a low zinc concentration, causes no degradation in the wiredrawing workability. The heat treatment after the wiredrawing produces the Cu-Zn alloy layer 5 with a high zinc concentration to ensure excellent electric discharge machining performance. The Cu-Zn layer as the outermost layer enables batch heat treatment of the composite wire rod to thus improve the productivity.
