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 melting and casting a metal, and an ingot for skin material is manufactured by melting 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.

An elastomer composition is provided which contains a matrix of poly-(3-hydroxybutyrate-co-3-hydroxyhexanoate) produced from microorganisms and crosslinked natural rubber particles dispersed like islands in the matrix. An eraser using the elastomer composition is also provided. The present invention is capable of providing an elastomer composition and eraser using the same, which can be recycled, are friendly to the environment, and corresponds to the recycling society, without relying on fossil resources.

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 furnished 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.

An MOS-type semiconductor device comprises two semiconductors separated by an insulator. The two semiconductors comprise monocrystal semiconductors, each having a crystallographic orientation with respect to the insulator (or other crystallographic/semiconductor property) different to the crystallographic orientation (or other respective property) of the other semiconductor. This arrangement of crystallographic orientations (and other crystallographic/semiconductor properties) can yield reduced unintended electron tunneling or current leakage through the insulator vis a vis a semiconductor device in which such an arrangement is not used. Methods for forming the MOS-type semiconductor devices of the invention are also provided.

The present invention relates to a novel shorted patch antenna device that a thickness of a conductor of an antenna, a location of a feeding point and a shape of an antenna element is easily adjustable and can be miniaturized, as well as a method therefor. The shorted patch antenna device includes: an antenna element that is composed of a folded single conductor plate and has a radiation conductor plane (2) formed on one of opposing planes of the conductor plate and a ground conductor plane (3) formed on the other plane of the opposing planes; a miniaturization section that is composed of a hole (5) formed on the ground conductor plane (3) and a slit (7) cut out from a side of the radiation conductor plane (2) or a matching adjustment plane (31) formed by bending a tip portion of the radiation conductor plane (2) toward the ground conductor plane (3); a coaxial line (8) whose inner conductor (9) extending through the hole (5) to the radiation conductor plane (2) is electrically connected to the radiation conductor plane (2) and whose external conductor (10) is grounded to the ground conductor plane (3); and a resin (16) that fills between the radiation conductor plane (2) and the ground conductor plane (3) of the antenna element.

Equipment for manufacturing skin material of a clad material includes a casting apparatus which melts and mixes a metal for the skin material different from the core material in their component compositions, and casts the skin material; an ingot-cutting apparatus which cuts an ingot for skin material which is cast by the casting apparatus; and a conveying apparatus which conveys the ingot for skin material among each apparatus. The ingot-cutting apparatus is a slicing apparatus which slices the ingot for skin material into a predetermined thickness.

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 ram 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).
