A transfer tool having a transfer film remover for abrading and removing various transfer films transferred on a sheet of paper or the like without scratching or staining the paper surface. A transfer film remover for abrading and removing a transfer film transferred on a sheet of paper or the like is provided in part of a case of a transfer tool for transferring coat film or other transfer film on a transfer tape onto a sheet of paper or the like. By the exclusive transfer film remover always furnish in the transfer tool, the transfer film transferred on the transfer area can be abraded and removed, and hence it is not dropped or lost.

Provided are a side member from which a clad member for heat exchanger exhibiting excellent productivity and corrosion resistance while preventing poor adhesion can be produced in production of a clad member for heat exchanger by controlling the surface state and flatness, a method for producing the side member, and a method for producing a clad member for a heat exchanger by using the side member. A side member (A) consists of a core material and one or more layers of side member (A) applied onto one side or both sides thereof and being used in a clad member for a heat exchanger, wherein a plurality of periodic forms (B) of fine groove which become arcuate toward one direction of the side member (A) is formed on the surface of the side member (A). The periodic form (B) of fine groove extends up to the outer circumferential edge of the side member (A) with a radius of curvature of 800-1500 mm and has a period (D) of 1-8 mm in the above-mentioned direction of the side member (A) and surface roughness of the side member (A) in the above-mentioned direction of 1-15 μm 10-point average roughness (Rz).

Skin material of a clad material is composed of one or more layers, each layer of the skin materials is made of a metal different from the core material in their component compositions, and at least one layer of the skin material has a cast microstructure, when the skin material is superposed on either of one or both faces of the core material.
摘要:
A method for manufacturing a clad material composed of a core material and one or more skin materials which are superposed on either one or both faces of the core material, includes a clad material preparation process where an ingot for core material is manufactured by dissolving and casting a metal, and an ingot for skin material is manufactured by dissolving and casting a different metal for skin material, without hot rolling. The ingot for skin material is superposed as a skin material at a predetermined position of either one or both faces of the ingot for core material and the superposed material is hot-rolled to manufacture a clad material.
摘要:
An abradant-containing eraser is disclosed which comprises an elastomer composition containing a matrix of a biomass plastic and crosslinked natural rubber particles dispersed like islands in the matrix of the biomass plastic, and an abradant. According to the present invention, it is possible to provide an abradant-containing eraser using an elastomer composition, which can be recycled, is friendly to the environment, and corresponds to the recycling society, without relying on fossil resources.
