A cloth edge control device for a sewing machine includes a pair of rollers, an optical sensor, and controller. The pair of rollers are arranged near a needle location in such a manner that the rollers are rotating about an axis perpendicular to a direction in which a cloth material is fed, so as to be pushed against the cloth material. The optical sensor is adapted for detection of the cloth material at a plurality of points on a line along a direction intersecting with the feed direction before the needle location. The controller detects the position and curvature of the edge of the cloth material according to a light intercept signal from the optical sensor and rotates the rollers independently of each other according to the position and curvature thus detected.

A filter unit comprises a metallic supporting plate possessed of stepped through holes opening with a larger diameter in one main surface and with a smaller diameter in the other main surface (wherein the diameter ratio of larger-diameter openings to smaller-diameter openings is desired to be in the range of 1:0.01 to 1:0.5) or a pressureproof supporting plate having in one surface thereof inclined liquid flow grooves arranged in a radial pattern and concentric circular liquid flow grooves adapted to intersect the radially arranged liquid flow grooves and a membrane filter disposed on the surface of the supporting plate containing larger-diameter openings or liquid flow grooves. This filter unit is ideally used for finely dividing and uniformly sizing suspended lipid particles assuming a definite average particle size and a specific particle size distribution. The high-pressure sizing apparatus and the method for production of suspended lipid particles utilize the filter unit constructed as described above and rely essentially for their operation on effecting fine division of lipid particles in the suspension by supplying the suspension of lipid particles from the membrane filter side under pressure and causing the suspension to pass through the membrane filter. Thus, they constitute themselves effective measures for pharmacological products and cosmetic products which are in need of lipid particles assuming a definite average particle size and a specific particle size distribution.
摘要:
A method of converting an area data, which is a rectangular or polygonal area data having an area, into a path data, which has both a series of central line segments and a width data. The area data is inputted into a computer where the area data is converted into the path data, based upon a connection relation among figures. The path data is then outputted by the computer. The method can also include the steps of determining whether or not the area data can be converted into one path data based upon whether or not the area data has an edge which fulfills a condition of the shape of the outline at corresponding corners, other than the first and last corners counted from one edge are the same, and when the corresponding corners are numbered from the one edge both clockwise and counterclockwise, all the rectangles whose opposite corners are the corresponding corners are included in the original figure. The method can also include the step of forming a path data by connecting the midpoints of corresponding two vertices when the area is determined to be convertible into one path data.

A suit material support device which comprises a center suit coat body support member and a pair of suit sleeve support members disposed on the opposite sides of the suit body support member. The suit coat body support member is rotatable from a suit coat body placing position and to right- and left-hand suit sleeve sewing positions. It has a plurality of suit body bars displaceable in planes intersecting each other at right angles and clamp needles for clamping suit sleeves against the suit body bars. A pair of suit sleeve support members are disposed on opposite sides of the suit body support member and each is rotatable between a suit sleeve attaching position and a suit sleeve placing position as the mechanism rotates. It has a plurality of sleeve bars movable for accommodating variation in the size of the suit sleeves and is displaceable in the plane of the axis of rotation of the suit sleeve support member to move the sleeve thereon into position for attachment to a suit coat body on the body support member.
