    摘要: The present invention is intended to provide a grinding wheel which is prevented from the one-sided wear or the wear taking place intensively at the outer side of the segments due to working load so as to improve the processed quality of the ground surface. Thus the invention proposes a grinding wheel comprising a plurality of segments attached to the underside of a rim part of a grinding wheel, a rim part for supporting the segments, rib parts for connecting the rim part with a disk part, and a disk part with a central hole for connection to a motor-operated tool, wherein the segments are each demarcated into the inner portion and outer portion around the demarcating interface and the outer portions are so treated as to constitute a higher wear resisting region than the inner portions by controlling the particle size and/or the content of the super abrasive and/or by controlling the hardness of the metal bonding material for binding the abrasive particles together, in order to prevent one-sided wear.

    摘要: The present invention relates to an improvement of the conventional sandwiched type saw blade shank by providing, as the intermediate layer, a coated thin sheet with tens of electro-conductive points or a thin sheet with multiple contacts to enhance weldability and to minimize the thermal deform or pressed marks, so that sound absorption, noise reduction and also heat dissipation may be maximized during a high speed cutting operation. The invention provides a saw blade shank with cutting tips on the circumference of the shank, comprising two or more conductive steel plates (22,24) and coated thin sheet (30) as an intermediate layer inserted between the neighboring conductive steel plates, the coated thin sheet being coated so as to leave a plurality of uncoated areas (32a) on at least one of its surfaces, whereby the coated thin sheets (30) and the steel plates (22,24) are integrally combined by multi-contact thermal fusion through a predetermined high pressure and electric current concentrated on the uncoated areas (32a).

    摘要: A control knob for a vehicle has an improved outward appearance by forming a boundary line between two different materials in a portion that is not visible and preventing abrupt differences in color due to light refraction. The control knob is produced by dual injection molding of two different materials, is installed on one end of a shift lever, and functions as a handgrip. The control knob includes an portion of opaque and transparent materials, an overlapping portion opaque and transparent materials, and a coated portion formed of paint applied to portions of the transparent portion that do not overlap with the opaque portion. A boundary surface between the opaque and transparent portions is such that a refractive index of light passing through the transparent portion from the overlapping portion is close to a refractive index of light passing through the transparent portion from the coated portion.
