    摘要: The speed control circuit comprises a full wave rectifier having its output connected to an adjustable D.C. voltage divider. A series circuit connected to an A.C. power source includes an electric motor and an anti-parallel connection of two thyristors. The gates of the thyristors are connected to the output of the voltage divider via separate trigger circuits each providing a different trigger voltage proportional to the setting of the voltage divider. In this manner one or both thyristors may be selectively activated and the electric motor can be driven with half the waves as well as with full waves of the power source.

    摘要: Disclosed is a device for producing embroidery pattern stitch data, wherein a pattern or patterns may be entered or selected from a memory (3) and the like and optionally positioned. It is discriminated if the selected pattern or patterns may be wholly received in a predetermined stitch area. If the selected pattern or patterns may not be wholly received in the stitch area and partly extend beyond the stitch area, print data may be produced for printing the selected pattern or patterns, and simultaneously for printing reference marks defining the positions and angles of the patterns relative to the work holding frame for holding the work to be stitched.

    摘要: An electronic sewing machine is disclosed in which a first memory stores a plurality of patterns, a second memory temporarily memorizes pattern numbers each specific to the patterns, a first switch and address pointing means enable the second memory to memorize a series of selected pattern numbers, and a second switch resets the address pointing means. The address pointing means also advances the address of the second memory such that a display indicates the pattern numbers one after the other in the desired order.

    摘要: A plurality of different stitch patterns are stored in a first static memory. A second static memory memorizes a combination of these different patterns in a predetermined sequence. A third static memory stores basic needle position signals each specific to the patterns stored in the first memory. Calculating means utilize signals derived from the second memory and the third memory to determine values for adjusting the swinging amplitude of the sewing needle with a common variation rate and for setting a common basic needle position.

    摘要: Disclosed is a specific adhesive polyethylene composition comprising [1] a modified ethylene/&agr;-olefin copolymer resin or elastomer obtained by modifying a specific ethylene/&agr;-olefin copolymer resin or elastomer, each of which comprises ethylene and an &agr;-olefin of 3 to 20 carbon atoms, with an unsaturated carboxylic acid or anhydride, ester, amide, imide or metallic salt derivative of a unsaturated carboxylic acid thereof, [2] an unmodified ethylene/&agr;-olefin copolymer resin and/or an unmodified ethylene/&agr;-olefin copolymer elastomer and [3] a tackifier. Also disclosed is a multi-layer laminated film of 3 or more layers in which a layer of the above composition is interposed between an ethylene polymer layer and either a polyamide resin layer, an ethylene/vinyl alcohol copolymer layer or a layer of a mixture of polyamide resin and ethylene/vinyl alcohol copolymer. The adhesive polyethylene composition shows excellent adhesion strength to ethylene polymers, polyamide resins and ethylene/vinyl alcohol copolymers, high heat-sealing strength and heat resistance. The multi-layer laminated film shows excellent strength, heat resistance and gas barrier properties, and besides this film has heat shrinkability, so that the film is suitably used as a shrink film.

    摘要: Disclosed is a device for producing embroidery data on the basis of image data, wherein jump threads extended between unit images are effectively prevented from being stitched into the embroidery stitches by using particular stitch data produced by successively searching the image data from above to set a stitch starting point of each unit image. The stitch data forms the stitches starting from the stitch starting point and terminating at the stitch starting point. Although the jump threads are produced between the stitch starting points, these jump threads will not be stitched into the embroidery stitches.
