Abstract:
An endless metallic belt has at its outer peripheral surface a layer provided with a compressive residual stress by shot peening, and also has at its inner peripheral surface a layer provided with a compressive residual stress by shot peening. In a method for manufacturing the endless metallic belt, both outer and inner peripheral surfaces of the endless metallic belt are subjected to shot peening, wherein the inner peripheral surface is shot peened prior to the outer peripheral surface. The method produces an endless metallic belt having its fatigue strength improved without suffering any significant deformation.

Abstract:
A thermosensitive recording material is provided which includes a substrate, a thermosensitive recording layer formed on the substrate and including a binder resin, a coloring agent and a coloring developer inducing color formation in the coloring agent upon application of heat thereto, and a protective layer formed on the thermosensitive recording layer and including a resin, wherein the protective layer includes a particulate organic filler (A) whose average particle diameter is from about 1.2 to about 3.0 times the thickness of the protective layer and a particulate organic filler (B) having an average particle diameter of from about 0.05 to about 0.7 .mu.m. The thermosensitive recording material has good image qualities without undesired white streaks and good ability to be used with thermal printheads without sticking to and wearing out the thermal printheads.
Abstract:
A brightening chemical polishing solution for a hardened steel article (e.g., a carburized and quenched gear) comprises hydrofluoric acid having a molar concentration of from 0.2 to 2 mol/l, hydrogen peroxide having a molar concentration of from 0.4 to 4 mol/l, and water, a molar ratio of the hydrofluoric acid to the hydrogen peroxide being from 1:1.5 to 1:2.8. The steel article is quench hardened and is chemically polished in the solution. A shot-peening is additionally performed, prior to the polishing.
Abstract:
A thermosensitive recording material is composed of a support, a thermosensitive coloring layer capable of inducing color formation upon application of heat thereto, formed on the support, and an overcoat layer formed on the thermosensitive coloring layer, the overcoat layer being essentially composed of a resin component which is crosslinked by a glycidylamine compound serving as a crosslinking agent for the resin component. A coating liquid for the formation of the overcoat layer is essentially composed of the resin component and the glycidylamine compound.

Abstract:
To provide a thermosensitive recording material, containing: a support; an under layer; a thermosensitive recording layer; and a protective layer, where the under layer, the thermosensitive recording layer, and the protective layer are provided in this order on at least one surface of the support, wherein the support is synthetic paper, or a synthetic resin film, wherein the under layer contains a binder resin, and hollow particles, wherein an adhesive force of the thermosensitive recording material at −20° C., as measured by the described measuring method of the adhesive force, is 10.0 N/25 mm or greater.
Abstract:
Provided are a steel having a non-magnetic portion, which can be applied to the steel of the remaining portion irrespective of the material and which has a structure of a short treating time required and a determined depth direction, its manufacturing method, and a revolving electric core. There is prepared an electromagnetic steel sheet having a recessed groove. A two-layered chip of a modifier metal foil and a stainless steel foil is so set in the groove of the electromagnetic steel sheet that the electromagnetic steel sheet and the stainless steel foil have surfaces of the same height. The modifier metal foil is melted when electric current is applied under pressure. When this pressing and current applying is continued, inner sides of the electromagnetic steel sheet and the stainless steel foil contacting the modifier metal foil are melted to form a nonmagnetic alloy layer in the region excepting the surface portions of an electromagnetic steel sheet layer and a stainless steel layer. The nonmagnetic alloy layer and the stainless steel layer do not pass a magnetic flux.
