Abstract: An osteosynthetic pin characterized in that the pin is formed substantially of a poly-L-lactic acid having a molecular weight of at least about 70,000, and is formed by axially drawing about 2 to about 10 times at an elevated temperature of about 70.degree. to about 120.degree. C.

Abstract: In a method of detecting a contacting position using a touch panel, a pair of resistance layers formed on two substrates are opposed with a gap. At least one conduction member is provided on one edge of one of the resistance layers and another conduction member is provided on one edge of another resistance layer which extends in a direction perpendicular to the edge of said one of the resistance layer. A constant current source is connected to one conduction member so that when the resistance layers contact at a contacting position, a constant current flows from the conduction member of one of the resistance layers to the conduction member of said another resistance layer through the contacting point. Thus, the coordinate position of the contacting point can be detected by the voltage drops on the respective resistance layers.

Abstract: A circular knitting machine comprising a knitting assembly for forming a tubular knitted fabric, fabric transport rollers for delivering the fabric from the assembly, a take-up spool for rolling up the delivered fabric thereon, and a pair of opposed frames stoppably rotatable about a vertical axis in synchronism with the knitting assembly. The rollers and the spool are supported by the frames. A constant torque is transmitted from a drive transmission for the frames to the transport rollers by a constant-torque transmission utilizing a magnetic force, while the spool is driven with power transmitted from the drive transmission through a belt transmission, so that the fabric knitted at a high speed can be rolled up properly. The spool comprises a pair of divided spool members and is therefore easily withdrawable from the rolled-up fabric.

Abstract: An apparatus comprising a movable frame reciprocatingly movable longitudinally of a tubular knitted fabric, a fixed press bed member spaced apart from the frame in the direction of transport of the fabric, at least one pair of upper and lower fabric feed rollers mounted on the frame and stoppably drivable in the transport direction, a tenter core member reciprocatingly movable with the frame for tentering the fabric as fitted therearound and having one end held by the feed rollers and the other end extending toward the press bed member, and a holding member for releasably pressing the fabric as tentered by the core member against the press bed member. The holding member is provided on the fabric facing side thereof with the cutter blade of a press cutter and elastic pieces.

Abstract: A rolling-up apparatus disposed below the knitting unit of a circular knitting machine has a pair of support frames rotatable and stoppable in synchronism with the knitting unit. A take-up spool, having a pair of spool members subdividing it lengthwise, is supported by the support frames and is rotatable about a horizontal axis. The spool members are advanced to a rolling-up position to clamp the leading end of the fabric and then rotated to roll up the fabric thereon. The spool members are withdrawn from the rolled-up fabric, which is then delivered from the knitting machine. The spool members are advanced again to the rolling-up position to roll up the subsequent portion of fabric, after part of it has been deflected into the path of the path of the spool members by a fabric shifting member.

Abstract: A proposal for detecting flaws not defining normal stitches in a knitted fabric. Fabric detection signals are derived from three detectors arranged to correspond to intervals between lines of thread defining stitches. The detection signals are then added with predetermined weights, and the signals thus weighted are subjected to adding and/or subtracting operations. As a result, the flaws not defining normal stitches in the knitted fabric are detected. According to this proposal, reliable detection is made of not only large flaws such as circular holes but narrow flaws such as runs also.
