Abstract: An effective thread number in the thread section which is disposed on the mouth section of the bottle is formed to be 2.2. That is, the thread section is formed such that the thread section 13 should serve effectively in the mouth section such that an interval between a start position and an end position should be 2.0 to 2.5. In the bottle can member 11 which has such a thread section, an outer diameter of the thread section which is formed on the mouth section is 28 to 38 mm. Also, the thickness of the mouth section is 0.25 to 0.4 mm. The thread section which has the effective thread number 2.0 to 2.5 is formed by eight-thread per inch pitch. By doing this, it is possible to put the cap desirably.

Abstract: Nip rollers 11 and 12 each including a pair of upper and lower rollers are disposed on an upstream side and a downstream side with a portion to be cut of an optical film F located therebetween. In the nip roller 12, a center axis C of the upper roller 12b is displaced relative to a center axis L of the drive roller 12a in a direction away from the portion to be cut. Upon cutting of the polarizing film F, the upper rollers 11b and 12b are simultaneously moved downward, so that a timing at which the downstream nip roller 12 nips the polarizing film F is delayed. Further, the nip roller 12 pulls the polarizing film F in the direction away from the portion to be cut, so that tension is applied to the polarizing film F. In this state, the polarizing film F is cut by a laser device 10.

Abstract: A suction table 9 is disposed at a cutting action position for a polarizing film F, and holding blocks 9a and 9b, which are different in height from each other, are disposed in proximity to each other along a transport direction on a surface of the suction table 9 to form a suction groove 14. Nip rollers 11 and 12 are disposed on front and rear sides of the suction table 9 to nip opposed ends of the polarizing film F. Further, the suction table 9 suction-holds the polarizing film F in a state that the polarizing film F is inclined with the suction groove 14 located below a portion to be cut. In this state, a laser device 10 scans the polarizing film F along the suction groove 14 to cut the polarizing film F in a width direction.

Abstract: A surface polishing method for enhancing crystal orientation on the surface of a tapelike metal substrate in order to enhance the critical current of a superconducting thin film. In an oxide superconductor comprising a tapelike substrate, an intermediate layer formed on the tapelike substrate, and an oxide superconducting thin film layer formed on the intermediate layer, the method for polishing a surface to be polished of the tapelike substrate comprises a step for polishing the surface to be polished while traveling the tapelike substrate continuously, wherein an initial polishing step and a finish polishing step are included. Ultimately, the average surface roughness Ra of the polished surface is 2 nanometer or less and the in-plane orientation ?? is 5° or less.

Abstract: A can manufacturing device in which a tool supporting base has: a plurality of working tool units that support a plurality of working tools; a supporting member that supports a plurality of working tool units; and a linear driving mechanism that reciprocates the working tool units with respect to the supporting member in the axial direction of a workpiece. The linear driving mechanism has: a guide section fixed on the supporting member with a base plate therebetween; a slide rail that is fixed on the working tool unit and slides along the guide section; an electromagnetic coil provided on the base plate; a magnet plate that is provided on the working tool unit and generates, between the electromagnetic coil and itself, a thrust force for the guide section; and a supply pipe that is provided at the electromagnetic coil and supplies coolant to the inside of the electromagnetic coil.

A surface of the tape-shaped substrate is polished by continuously running the tape-shaped substrate. The polishing step includes initial polishing process and finishing process which are carried out such that the average surface roughness Ra of the substrate becomes 2 nanometers or less and the in-plane directionality of the intermediate layer becomes 5° or less after the polishing step.

Abstract: In a bottle-shaped can manufacturing method and a bottle-shaped can, a necking process is performed on an opening portion of a cylindrical workpiece with a bottom several times to form a body, a shoulder, and a portion for forming a neck that is continuously connected to an upper end of the shoulder in the axial direction of the bottle-shaped can and extends upward, and a first convex is formed in at least one of a connection portion between the shoulder and the portion for forming the neck and a connection portion between the shoulder and the body. Then, the shoulder is pressed to the inside of the body while the first convex is recessed inward in the radial direction, thereby forming grooves in the shoulder.
