A punch () and a pad () are opposed to each other such that a molded portion () of a metal laminate film () to be processed is interposed between the punch () and the pad (). An enclosed space () is compressed to raise only the temperature of the molded portion () while keeping the vicinity of the molded portion () at a low temperature (S, S). After that, the enclosed space () is moved with respect to the molded portion () to perform first molding (S) on the molded portion (), and then gas in the enclosed space () is released to perform second molding (S) on the molded portion () by means of the punch () and the pad ().

A coloring matter absorbing a near-infrared ray which comprises a diimonium salt containing a sulfonimide as an anion moiety, represented by the general formula (1): wherein R may be the same or different and represents a moiety selected from the group consisting of an alkyl group, a halogenated alkyl group, a cyanoalkyl group, an aryl group, a hydroxyl group, a phenyl group, and a phenylalkylene group, and Rand Rmay be the same or different and each represent a fluoroalkyl group, or together form a fluoroalkylene group. The coloring matter absorbing a near-infrared ray is excellent in the resistance to heat and moisture, and thus exhibits an ability of absorbing a near-infrared ray not lowering for a long period of time. A filter for cutting off a near-infrared ray manufactured by using the coloring matter can be advantageously used for wide applications such as a plasma display panel, an optical lens, a glass for an automobile, and a glass for a building material, due to its excellent resistance to heat and moisture.

The present invention provides a linear motor, which can improve motor efficiency and which can be manufactured by a simplified procedure. The linear motor of the present invention includes a movable unit of cylindrical shape and having the central axis at the intersection of the X-axis and the Y-axis. An inner yoke is arranged on an inner side of the movable unit with a given spacing in the radial direction of the movable unit and is formed by laminating a multiple of thin plates each in approximately rectangular in shape and having strong magnetic permeability arranged in the direction of the X-axis. An outer yoke is arranged on the outer side of the movable unit with a given spacing in a radial direction of the movable unit and is formed by laminating a multiple of thin plates, each approximately rectangularly shaped and arranged in the same direction as the thin plates of the inner yoke. A pair of permanent magnets are magnetized in a direction from the inner yoke to the outer yoke. The thrust force of the linear motor is stable and motor efficiency is improved.

Efficient cylindrical linear motor

A linear motor comprising prismatic inner yokes each constructed in a manner that a large number of sheets each having a generally rectangular configuration and having a high magnetic permeability are piled up each other and outer yokes each constructed in a manner that a number of sheets each having a generally rectangular configuration and having a high magnetic permeability are piled up each other. Each of coils is wound around a central portion of three magnetic pole portions of the outer yoke to alternately establish different magnetic poles along a direction of an axis of the linear motor. A surface of the outer yoke, holding the magnetic pole portions, is disposed in an opposed relation to the inner yoke to define a predetermined gap therebetween so that the inner yoke and the outer yoke form each of a plurality of yoke blocks. The yoke blocks are placed around the axis so that the sheet piling-up direction is perpendicular to a diametrical direction of a shaft. In addition, a moving element having a pair of permanent magnets magnetized radially so that their magnetizing directions are opposite to each other is movably located between the inner yoke and the outer yoke at a predetermined interval along the axis. This construction improves the motor efficiency and facilitates the manufacturing of the motor.

Cold rolling method for a metal strip and a mill array

A method for improving the resistance to surface roughening of tungsten-containing metallic articles such as cutting tools and hot mill rolls made of a cemented carbide or high-speed steel and extending the lifetime thereof. The method comprises treating a metallic article with an aqueous alkaline solution containing calcium ions and optionally tungstate ions having a pH greater than 8 so as to form a coating of calcium tungstate on the surface of the metallic article. In hot rolling with tungsten-containing rolls, the aqueous solution can be used as at least part of a cooling water to cool the rolls, thereby extending the period before roll replacement becomes necessary due to surface roughening and decreasing the frequency of roll dressing required during hot rolling.

Method for minimizing surface roughening of tungsten-containing rolls

The invention provides a method for improving the luster of a metal sheet surface without deteriorating the productivity and also in reducing the difference in glossiness between the upper and lower surfaces of the metal sheet at the time of cold-rolling. By making the velocity, after rolling of the metal sheet, equal to or larger than the rotational circumferential velocity of the work rolls, and by rolling the metal sheet with upper and lower work rolls crossed with each other in such manner that an angle of slip scratches left on the metal sheet surfaces becomes 5 degrees or larger and shear deformation in the widthwise direction can be effectively given to the metal sheet just before rolling, thereby improving the surface luster of the metal sheet. In addition, in the case where luster of the metal sheet surface is improved by changing the cross angle between the upper and lower crossing work rolls, the sheet configuration is corrected by a configuration control actuator, depending upon the sheet configuration of the metal sheet after the cross angle is changed. Furthermore, the difference in glossiness between the upper and lower surfaces of the metal sheet is reduced by selecting the cross angles formed by the upper and lower crossing work rolls with respect to the direction at right angles to the rolling direction and also employing rolls having different surface roughness as the upper and lower work rolls.
