Abstract: A method and apparatus for smoothing a fragile, flexible card 12 on a perforated plate. The method includes first locating and clamping the card on a tray 10 having an open center, and disposing the tray and card on the plate 48. The plate is located on a hollow platen 32 which is evacuated to draw the card to the plate. The hollow 40 of the platen has a center compartment 64 and peripheral compartments (66,68) located about the center compartment. The evacuation process begins with the center compartment and gradually evacuates the peripheral compartment such that the center portion of the card is drawn first to the periphery plate while the peripheral portions of the card are drawn later to the periphery of the plate. In this manner, the smoothing process begins with the center of the card and progresses outwardly from the center to the periphery of the card.

Abstract: A magnetic ball (1) comprises a hollow sphere (2) of magnetic material and a resilient covering (3). 
     A target substituting for a golf hole has two parts, a thin plate (4) of permeable magnetic material, and a cylindrical permanent magnetic (5) of significant thickness mounted upon the plate. 
     The plate size is approximately equal to that of a golf hole. The magnet (5) physically obstructs the passage of a ball over the plate, the thickness of the magnet being chosen to give the desired degree of obstruction. The magnet is strong enough positively to locate a ball on the plate.

Abstract: Photosensitive materials of the positive charging type which are useful in electrophotography are described. The material comprises a conductive support of any desired form and a photoconductive layer formed on the support. The photoconductive layer is made of X-type and/or τ -type phthalocyanine compound dispersed in a binder resin. The compound is dispersed partly in a molecular state and partly in a particulate state in the resin. To make such a dispersion, the compound is agitated in a solvent along with the binder resin until charge transferability and charge generating ability are developed in the resultant photoconductive layer. Fundamentally, single-layer photosensitive materials with good photosensitive characteristics and a high heat resistance can be obtained.

Abstract: The apparatus of the invention is provided with a contour pick-up unit (16) that finds a coordinate value sequence of contour pixels by tracing the contour of a figure from pixel data obtained by scanning the figure stored in a first image memory (14), and a protuberance coefficient calculation unit (18) which converts the contour pixels into protuberance coefficients that represent protuberant condition from the coordinate value sequence of contour pixels found by the contour pick-up unit (16). A contour line discrimination unit (20) discriminates, based on the protuberance coefficients converted by the protuberance coefficient calculation unit (18), which one of the characteristic components consisting of linear component, curve component, connection component, complex component and tiny component forms the above contour pixels. This unit then stores the label ("1", "2", "3", "4", "5") indicating the characteristic components in an address corresponding to a contour pixel which is discriminated in a second image memory (22). A label propagation unit (24) determines a characteristic component of a pixel in the line surrounded by the label based on the label stored in the second image memory (22) and the pixel data stored in the first image memory (14), and stores the label indicating the characteristic component in the address corresponding to a pixel in the line that is determined in the second image memory (22).
