Title: Reflecting mirror
Inventor: YAMAMOTO HIROSHI
IPC: B23K26/06
Filed: 2002-05-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a reflecting mirror which can align teaching light to a processing laser beam and produce an easily visible target with a sharp contour.  <P>SOLUTION: A reflecting mirror 3 is constituted by joining a slope face 6a of a prism 6 to the back face 5b of a glass plate 5 (glass layer). The mirror prevents teaching light 1b split by the surface 5a of the glass plate 5 and transmitting the glass plate 5 from propagating in the same direction as teaching light 1a reflected on the surface 5a of the glass 5 to propagate to the welding torch. Thus only the teaching light 1a reflected on the surface 5a of the glass plate 5 propagates to the welding torch, and the teaching light can be aligned to the processing laser beam and an easily visible target having a sharp contour can be obtained.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-04-19
Abstract: <P>PROBLEM TO BE SOLVED: To obtain a non-hygroscopic and strong heat insulating material for solving the problem that a foam is excellent in heat resistance but the absorption of moisture in the foam results in lowering of the heat insulation and the lack of strength.  <P>SOLUTION: A skinned foam composite body can be formed by one process by putting powdered plastic and crosslinked expanding particular bodies of polyolefin in a mold and heating them under rotation.
