A rotary spinning ring structure for use on a spinning frame or the like comprises, as principal components, a stationary tube fixedly supported on a ring rail, a slide ring, a rotating tube assembly supported for rotation by the slide ring on the stationary tube, and a balancing mechanism incorporated into the rotating tube assembly. The rotating tube assembly comprises a rotating tubular body made of an antistatic synthetic resin material, a circular brake ring made of an antistatic synthetic resin material and joined to the rotating tubular body, and a dust cover made of an antistatic synthetic resin material and put on a middle portion of the rotating tubular body. Each of the antistatic synthetic resin materials forming the rotating tubular body, the brake ring and the dust cover is a mixture of a synthetic resin, and fibers, powder or flakes of a conductive material, such as carbon and has a low volume resistivity.

A spinning ring structure (10) for twisting a fleece into a yarn and taking up the yarn on a bobbin (82) comprises a stationary ring (20) fixedly mounted on a ring rail (74), a rotary ring (30) disposed for rotation about its own axis inside the stationary ring (20) coaxially therewith so as to surround the bobbin (82) disposed with the stationary ring (30). A traveler (50) is put on the rotary ring (30) so as to revolve along the circumference of the rotary ring, and a brake ring (60) is mounted on the rotary ring (30) and provided with a plurality of radial vanes (68) to which air applies resistance against the turning of the brake ring. The brake ring (60) is provided with an air pressure evading wall (64) for avoiding the influence of a pressure generated by whirling air currents produced by the rotating cop, on the brake ring (60) to prevent retardation of the variation of the rotational speed of the rotary ring according to the variation of the effective circumferential speed of the cop built on the bobbin during a cop building operation so that a balloon formed by the yarn will not expand and will not collapse.

A gate valve device which includes a partition wall having an opening, a valve member movable along the partition wall to open or close the opening, a driving system for moving the valve member, and a pressing mechanism for pressing the valve member toward the partition wall. The pressing mechanism has a pressing member projectable toward and retractable from the valve member, wherein the pressing mechanism presses the valve member against the partition wall when the valve member is in a position closing the opening.

A plurality of circuit blocks are arranged in the longitudinal direction in which data is transferred, and this pattern of the longitudinally arranged circuit blocks is repeated laterally. The identical circuit blocks repeated laterally are provided with a common control line pattern. The main power-supply line pattern is formed longitudinally on the axes of symmetry for the repetition of the circuit blocks.

An annular cutter connecting apparatus includes an arbor, annular cutter fixing locking members received in holding holes formed in the lower end portion of the arbor and a sleeve member surrounding the lower end portion of the arbor, for fixing an annular cutter to the arbor. The sleeve has a first control face having an inner diameter equal to the outer diameter of the lower end portion of the arbor, for projecting the locking members into the central bore by a predetermined length when the first control face engages the locking members, and second control faces formed circumferentially in the first control face, for receiving the locking members. The sleeve is rotatable around its own axis so as to cause the locking members to selectively face the first control face and the second control faces, respectively. An annular cutter has a shank portion provided with locking member passing portion or portions on that part of the outer peripheral surface of the shank portion which corresponds to the holding holes of the annular cutter connecting apparatus. The shank portion has depressed locking member receiving portion formed in or on the locking member passing portion or portions and receive the locking members. The annular cutter is connected to and removed from the arbor in one-touch operation.

An image processor includes an image memory for storing image data; a data memory for storing graphic data; a display unit for displaying the image data and the graphic data; an input unit for giving an instruction to trace; and a semi-automatic image trace processing section for processing the line image of the image data. Two points on the contours at both sides of line image are set as trace base points for the line image, and the line image is traced, while determining end points and branch points, by moving the two trace base points on the contours at both sides of the line image concurrently in the same directions, while monitoring a relationship between the two trace base points and absorbing some noise of the different line widths.

A pattern recognition apparatus is capable of subjecting a large image region to image processing with an image memory having a small memory capacity and providing a contouring line data of an image in the same manner as processing with an image memory having a large memory capacity. The pattern recognition apparatus is provided with an image input means for inputting an image; an image data storing means for storing image data; a contouring line data storing means for storing contouring line data; and a contouring line data connecting means. The contouring line data connecting means is to partition image data into adjacent partitioned regions so as to allow them to overlap with each other by only one pixel, to delete a contouring line data in an overlapping portion of the adjacent partitioned regions from a contouring line data for the image data in each of the partitioned regions on the basis of a vector data passing in a predetermined direction, and to connect the contouring line data of an open drawing so as to match their terminal points in the overlapping portion thereof with each other, thereby providing a total contouring line data.

A partitioned image processing device executes image processing of large size drawing data using an image memory of small capacity to provide substantially the same processed result as that obtainable by using an image memory with a large memory capacity. An image data input device for inputting the image data; an image memory for storing the image data; and an image processing device for performing the image processing of the image data read in the image memory are provided. The image processing device is designed to partition the image data read-in from the image memory into partitioned regions; to read the partitioned regions of the image data in the image memory so that the portions of the image data in the adjacent partitioned regions partly overlap with each other, and to execute the image processing of each of the partitioned regions.

An image processing device which is designed to trace a pixel line in a pixel line data and provide a polygonal line data. The image processing device is provided with a pixel line tracing means for forming a tracing dot data by tracing one pixel after another in the pixel line, a tracing direction selecting means for selecting a direction substantially coinciding in a branch direction with the pixel line tracing direction on the basis of the tracing dot data obtained so far by judging the branch direction nearby a pixel at the branch point when the pixel line tracing means detects the pixel at the branch point by tracing, and a polygonal line processing unit for forming a polygonal line data by selecting a pixel line tracing direction by the tracing direction means, causing the pixel line tracing means to continue the tracing of the pixel line in substantially the same direction over the branch point, and forming a tracing dot line. The image processing device permits an effective processing of polygonal lines in the image processing.
