Abstract: The objective of the present invention is to easily acquire necessary information at arbitrary times.

Abstract: A raw material including a mixture of a natural fiber and a thermoplastic fiber is supplied to a surface of a rotating rotary body. The natural and thermoplastic fibers are scattered toward a carrying surface of a conveyor belt by the rotational force of the rotary body. An air blower may direct pressurized air to the scattered raw material in order to further effect separation of the natural and thermoplastic fibers. Consequently, the natural fibers and the thermoplastic fibers are deposited such that the relative concentration of the natural fibers and the thermoplastic fibers gradually and seamlessly changes or varies across the thickness of depth of the resulting molded fiber material.

Abstract: A raw material (12) comprising a mixture of a natural fiber and a thermoplastic fiber is supplied to the surface of the rotating rotary body (11). The natural and thermoplastic fibers are scattered toward the carrying surface of the conveyor belt (15) by the rotational force of the rotary body (11). An air blower (14) may direct pressurized air to the scattered raw material (14) in order to further effect separation of the natural and thermoplastic fibers. Consequently, the natural fibers and the thermoplastic fibers are deposited such that the relative concentration of the natural fibers and the thermoplastic fibers gradually and seamlessly changes or varies across the thickness or depth of the resulting molded fiber material (50).

Abstract: A system for reusing water soluble slurry waste fluid wherein separated available abrasive grains and extracted water soluble coolant are reused. This system is capable of reducing a disposal cost due to a reduction of a load to a waste water disposal plant by effectively reusing water soluble slurry waste fluid, and making a contribution to a reduction of a total slicing cost by reusing abrasive grains and water soluble coolant.

Abstract: In a wire saw for slicing a cylindrical workpiece such as a silicon ingot so as to obtain wafers or the like, the feed rate of slurry fed to the workpiece, the viscosity of the slurry, or the feed rate of a wire is varied according to the cutting length in the workpiece or the angle between the wire and the circumference of the workpiece. It becomes possible to obtain wafers or the like, each having a uniform thickness.

Abstract: A method of manufacturing wire for use in a wire saw used for slicing a semiconductor ingot into wafers is disclosed. A starting wire, which is an iron or iron alloy wire plated with copper or copper alloy, is drawn into a fine wire in a finish drawing step. Subsequently, copper or copper alloy plating is removed from the fine wire surface through chemical polishing with an acid treatment solution or a like solution, physical polishing with polishing cloth or the like, or electropolishing, or through combined polishing thereof. The method makes it possible to manufacture wire having excellent quality characteristics without raising a problem such as metal contamination of product wafers sliced from the ingot.

Abstract: A wire saw apparatus which is less susceptible to loosening of the wire and to breakage thereof, includes a wire supply spool, a cutting head having a plurality of main rollers around which a wire from the wire supply spool is wrapped, a wire take-up spool for taking-up the wire from the cutting head, and a plurality of guide rollers for guiding the wire which are arranged between the wire supply spool and the cutting head and between the cutting head and the wire take-up spool, wherein each of the guide rollers has a peripheral groove having a square-shaped section with a width of 2-20 times the diameter of the wire, and the number of turns of the wire which is wrapped around each guide roller in the groove having a square-shaped section is not less than 1 and not more than 5.

Abstract: A method of slicing a semiconductor single crystal ingot by a wire saw slicing apparatus and a semiconductor wafer produced by the method, in which the running direction of the wire is not corresponding with the cleavage directions of the semiconductor single crystal ingot so that occurrence of cracks or breakage in the semiconductor wafer produced by the method can be suppressed significantly without any additional processes or an increase in cost.

Abstract: A water-soluble cutting fluid is produced by dissolving a polymer fatty acid triglyceride imidazole, 2-methyl-1-stearate, and boric acid imidazole in the dispersion of inorganic bentonite in water thereby preparing a main component and adding oleic acid (agent for enhancing the lubricity), Na salt of ethylenediamine tetraacetic acid (metallic ion adsorbent), benzotriazole (rust-preventing auxiliary agent), and a silicone type defoaming agent to the main component.

Abstract: In a method and an apparatus for correcting a hardening deformation of an annular element made out of steel, during the cooling stage of hardening, the annular element which still has an austenitic structure is subjected to working on either the outside or inside diameter, with the degree of working being 0.05-1.0% if it is on the outside diameter with the annular element being pressed into a mold, and 0.5-3.0% if the working is on the inside diameter. Thus the deformation that develops in annular steel elements due to heat treatments is effectively corrected to yield completely round, strain-free or deformation-free annular elements.

Abstract: An improved odorless polyolefin resin composition is proposed which is free from the problem of the generation of unpleasant odors unavoidable in the conventional polyolefin resin compositions filled with an inorganic filler due to the oxidative degradation of the ingredients. The deodorant effect in the inventive compositions is obtained by formulating limited amounts of a secondary alkane sulfonate having 12 to 20 carbon atoms per molecule and an organic nitrogen compound having at least one skeletal structure expressed by the formula ##STR1## in a molecule as exemplified by melamine and the like into a polyolefin resin-inorganic filler blend.
