摘要： PROBLEM TO BE SOLVED: To obtain a yarn useful for diversifying a stretch material, controlled in stretchability and capable of being woven in the same texturing procedures as those of a usual yarn when preparing for weaving and weaving and readily providing a highly stretchable woven fabric by using a yarn rich in stretchability as a core yarn and carrying out the covering processing of a water-soluble yarn on s sheath yarn. SOLUTION: A yarn 1 rich in stretchability such as an elastic yarn, e.g. a polyurethane-based yarn or a polyester elsatomer-based yarn is used as a core yarn 1 and the covering processing of a water-soluble fiber such as a polyvinyl alcohol-based fiber is carried out on a sheath yarn 2. Furthermore, the resultant composite yarn 3 is preferably used as a warp yarn to produce woven fabric.

摘要： PURPOSE: To provide an x-y-θ fine movement stage capable of positioning in the accuracy of few tenth micron in x-axis, y-axis and θ-axis directions as a moving device for a measuring object in such measuring devices as metal microscope and scanned electron microscope with a small and light weight and simple structure. CONSTITUTION: For drive source of movable table 9, cylindrical piezoelectric element 6 with three or four poles is used and extension and bending motion of element upper surface caused by impressing pulse voltage to the piezoelectric element is utilized to move the movable table. As the displacement of the movement is small, an equilateral triangle displacement magnifier mechanism 8 is contacted to the upper surface of the cylindrical piezoelectric element to magnify the displacement. Furthermore, a cone upper projection is contacted to the upper surface of the displacement magnifier mechanism to reduce the effect of friction force between the movable table and the upper surface of the displacement magnifier mechanism and the movable table is loaded on it. The movable table is driven to back and forth, left and right or rotation directions according to the difference of vibration mode of the cone upper projection.

摘要： PROBLEM TO BE SOLVED: To provide a surface roughness measuring device using two-dimensional photo-electric transferring element alley which can make high reliability measurement of means roughness in short time even though the object to be inspected has a free curved surface without being influenced by a micro-displacement of the objected in an non-contact condition based upon the diffused light distribution analytical method. SOLUTION: To a surface to be inspected 5, parallel beams 2 of light are radiated in the normal direction, and the diffused light distribution from the surface 5 is received by a two-dimensional photo-electric transferring element alley 7, and image data is formed from the detected output of this element alley 7, and if the intensity distribution of the diffused light 6 is assumed as a three-dimensional body on the image exhibited on the screen of a display 11 as the spreading situation data of the diffused light distribution, the center of gravity of this three-dimensional body is determined as the center of gravity of the intensity distribution, followed by calculation of the ratio of the total intensity of the diffused light 6 between two regions having differing areas centering on the position on plane of this determined center of gravity, and the obtained ratio is compared with the evaluation data 16 where the previously measured ratio of the total intensity is related to the mean surface roughness, and thereupon the roughness of the surface 5 is evaluated.

摘要： PURPOSE:To orientate crystal axis to C axis of easy-to-magnetizing axis by allowing the surface temp. of cooling surface brought into contact with molten metal to be the solidified finishing point or below, setting the casting temp. higher than the solidified starting point of alloy and controlling the cooling speed. CONSTITUTION:The molten alloy consisting essentially of rare earth element, transition metal and boron is injected onto a rotating roll surface from a nozzle and rapidly cooled and solidified to continuously cast ribon-shaped strip. Then, the surface temp. of cooling surface brought into contact with the molten metal is heated from 50 deg.C to the solidified finishing point of alloy. The casting temp. is set to the temp. higher than the solidified starting point of alloy by 50-150 deg.C. Further, the cooling speed is controlled to 10-10 deg.C/sec. By this method, the thin strip of anisotropy magnetic material having excellent magnetic characteristic can be produced even by eliminating two step treatments.
