Abstract: TYhe curtain drawing device providing either manual or automatic drawing of a curtain comprises an electric motor, a curtain rod which is driven rotatably by the motor, an exteriorly-protruding longitudinally-extending spiral element attached to the outer circumference of the curtain rod and a plurality of rings through which the curtain rod passes, each of which have a diameter larger than the diameter of the curtain rod, so that the curtain which is suspended from the rings can be drawn manually or by rotation of the curtain rod. An automatically-releasing tassel holder which can be operated by remote control may be provided.

Abstract: A shaft produced by the steps of rolling inorganic fiber cloths around a plastic resin base body into a cylindrical shape to form a shaft body, coiling two sets of carbon cloth tapes in the opposite directions around the shaft body, and impregnating resin into the shaft body and carbon cloth tapes to integrate them into a single body. The shaft obtained by the method is light and strong and shows excellent resiliency. The shaft is particularly advantageous and reliable for golf clubs, fishing poles, and the like.

Abstract: In preparing for the sewing of fancy or complicated stitch patterns, on a sewing machine provided with a feed dog able to feed sewn material both forwards and backwards and also provided with a transversely shiftable needle for implementation of zig-zag effects, the sewing machine is operated as if to sew the stitch pattern desired, but without any cloth actually present beneath the machine's needle. The movement of the machine's feed dog and the transverse or zig-zag shifting of the machine's needle are both detected by transducers which generate corresponding electrical signals. These signals are processed and converted into a form suitable for application to the x- and y-inputs of an x-y recorder, which then generates a display of what the thusly simulated stitching pattern will look like when actually stitched on cloth. The transverse shifting of the machine's needle is readily detected and unproblematic because of its definiteness.
