Abstract: An abnormal pattern detecting apparatus comprises an image operating device which generates a soft tissue image signal representing a soft tissue image, a bone image signal representing a bone image, and an original image signal representing an original image from several image signals representing radiation images of an object, which radiation images have been recorded by exposing the object to at least two kinds of radiation having different energy distributions. A prospective abnormal pattern finding device finds prospective abnormal patterns, which appear in the soft tissue, bone, and original images, by processing the corresponding image signals with an abnormal pattern finding filter. A bone pattern finding device finds information about the positions of bone patterns appearing in the radiation image.

Abstract: A radiation image read-out method comprises the steps of exposing a stimulable phosphor sheet, on which a radiation image having a background region has been stored, to stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, and detecting the emitted light in order to obtain an image signal representing the radiation image. The shape and location of the background region are determined in advance, and only the area outside of the background region on the stimulable phosphor sheet is exposed to stimulating rays. Light emitted from the area outside of the background region is detected and converted into an image signal. Alternatively, after the shape and location of the background region are determined, the background region is erased. Thereafter, the stimulable phosphor sheet is exposed to stimulating rays, and light emitted by the stimulable phosphor sheet is detected and converted into an image signal.

Abstract: Calculations are made to find the differences, .DELTA.ij=fij-f0, between the value of an image signal component f0 representing as picture element P0 in a radiation image and the values of image signal components fij representing the picture elements Pij, which are located on each of a plurality of lines Li, where i=1, 2, . . . , n, extending from the picture element P0 to the peripheral parts of the radiation image, and which are spaced a plurality of distances rij, where j=1, 2, . . . , m, from the picture element P0. A representative value, which is representative of the differences .DELTA.ij, is then found for each of the lines Li. A mean-level value of two representative values for each set of two lines, which extend from the picture element P0 in approximately opposite directions, is then calculated.

Abstract: A spindle device has a housing, a hydrostatic fluid bearing in the housing, a spindle rotatably supported in the hydrostatic fluid bearing, a bracket securely mounted on the housing, a roller bearing on the outer circumference of the bracket concentric with the spindle, a pulley mounted on the roller bearing, and a connector connecting the pulley with the spindle for transmitting rotation of the pulley to the spindle.

Abstract: A positioning device includes an X-direction slide table and a Y-direction slide table which are slidable in directions perpendicular to each other. Stops are adjustable as to their relative positions with respect to the slide tables to define accurate stop positions of the slide tables. Cams and levers shift the slide tables. Biasing devices bias the slide tables against the stops. A linear drive shifts at least one of the slide tables over a predetermined distance against the respective biasing device.

Abstract: An improved high pressure glass column for high performance liquid chromatography which comprises, both ends of the high pressure glass column on which flanges made of the same glass material are arranged, two column end fitting plugs which are made of a fluorine-contained resin and have a small bore for the effluent flow bored in their center, a piston part of a fitting plug inserted in the bore syringe part of the column end and a flange arranged to attach to the flange of the glass column tube, where the inside of the end of the piston part is formed with a conic shape and one or more narrow circled hollows are formed around the outlet of the piston part, two filters made of the fluorine-contained resin placed in between the both ends of the piston part of the fitting plug and the solvent material packed into the column, and two clips fitting and holding the two flanges of the column and the plugs.

Abstract: The present invention discloses a film capacitor and a method for making the same. A capacitor element formed by rolling or laminating metalized films less than 3.5 microns in thickness has ends coated with ion plating to form block terminals so that the strong bonds between the ends of the capacitor element and the terminals may be obtained with the resultant decrease in contact resistance therebetween. In order to increase the mechanical strength of the terminals a conducting layer may be formed on the terminals by metal spraying, and in order to increase the bond the ends of the capacitor element may be subjected to etching prior to ion plating so that the roughed end faces offer teeth to which the metal terminals cling. Thus the present invention provides a film capacitor which is considerably compact in size, light in weight yet highly reliable and dependable in operation and inexpensive to manufacture.
