Abstract: The invention provides a spinal neuron damage treating agent for use in the treatment of spinal neuron damage, or an agent for promoting the proliferation of spinal neuronal precursor cells in the culture of spinal neuronal precursor cells, or an agent for promoting the regeneration of spinal nerves after transplantation of cultured spinal neuronal precursor cells, and the like. The invention provides an agent that contains a substance (e.g., ghrelin) that acts on the growth hormone secretagogue-receptor as an active ingredient, the agent being a spinal neuron damage treating agent for use in the treatment of spinal neuron damage, or an agent for promoting the proliferation of cultured spinal neuronal precursor cells in the culture of spinal neuronal precursor cells, or an agent for promoting the regeneration of spinal nerves after transplantation of cultured spinal neuronal precursor cells, and the like.

Abstract: A stitch data processing apparatus which can produce an embroidered pattern utilizing an automatic sewing machine from a pattern of any relative size. The pattern to be embroidered on a work piece is input to the stitch data processing apparatus via a charge coupled device. The charge coupled device produces an image which is displayed on a display device. An operator scales the image to fit onto the display device and then indicates points along the contour of the embroidered pattern and defines regions in which the automatic sewing machine will complete the embroidered pattern. The stitch data processing apparatus is capable of creating curved contours from a number of discreet points input by the operator. It is also possible to control stitch density.

Abstract: A data processing device for a sewing machine stores basic pattern data indicating the relative position between a needle and a material holding unit and including X and Y components of an X-Y coordinate. After setting a reference point on the X-Y coordinate plane and two angles (.alpha.i, .beta.i) based on an X-axis and a Y-axis around the reference point, the data processing device rotates the X and Y components of the basic pattern data on the basis of the two angles (.alpha.i, .beta.i) to form a transformed pattern, and stores the transformed pattern data. The processes such as rotation, inversion and inclination are executed by a single operation by designating the angles (.alpha.i, .beta.i).

Abstract: Herein disclosed is a data processing system for a sewing machine, which system comprises: a needle adapted to be moved upward and downward; holding means for holding a material to be stitched; and means for causing a relative movement between said needle and said holding means on the basis of a pattern data indicating a positional relationship therebetween.

Abstract: A sewing machine with thread take-up mechanism is so constructed as to vertically move a take-up member, supported on a needle bar in such a manner as to be vertically movable at a timing which is different from that of the movement of the needle bar on which the take-up member is moved. The take-up member has a hole through which a thread being lead to the sewing needle is inserted.
