摘要： PURPOSE:To obtain an optimum residual image by changing the luminous amount of a bias line light emitting source irradiating a photoelectric face of an image pickup tube. CONSTITUTION:The bias light emitting source 10 is provided in an optical branching device 5 to irradiate the photoelectric face of the image pickup tube 6A of a television camera 6. Three(11A-13A) bias light driving power supplies having different voltage are provided to form selectively the residual image among short, medium and long images by means of button switches 11-13. Since the change in the bias light emitting source 10 causes the change in a dark current and changes the pedestal level, power supplies 11B-13B are provided for the correction, they are selected in interlocking with the selection of the bias light driving power supply by means of the button switches 11-13 to change the pedestal level of a pedestal clamp circuit 7A in a TV camera control unit 7.

摘要： The X-ray source (2) irradiates an examined object (3), behind which an image detector (4-6) is fitted. The X-ray image is amplified by an X-ray beam intensifier tube (4), converting the image into an optical one. The latter is converted by a video camera (6) into a video signal. An optical system (5) focuses the optical image onto the camera. The dia. of the input image of the X-ray beam intensifier tube is 250-400 mm and the dia. of the tube output image is 50-90 mm. The dia. ratio of the input to output image is 4 to 8. Pref. the image detector is secured to a table, on which the examined object also rests. ADVANTAGE - Improved three dimensional resolution, and compact detector.

摘要： PURPOSE:To smoothly digitize an inspection image by imprinting an inspection image of an object into roll film and magnetically recording graphic information on photographed frames on the magnetically coating part of the film in digital amount. CONSTITUTION:First, digital graphic identification information on the object 5 is inputted from a graphic identification information input part 18. The information is filed in a graphic identification information storage circuit 19 in order. When a photographing signal S1 is issued from a control signal generating circuit 12, X-rays 13 from an X-ray tube 7 are projected on the object 15, and its transparent X-ray image is transformed into an optical image by an X-ray detector 8, led to a photographing camera 10 and imprinted to the roll film 14. When the film 14 is fed frame by frame, the circuit 12 generates an image start recording signal S3, and an image start signal generator 20 generates an image start signal ST indicating an image position. The signal ST is recorded in the magnetically coating part of the film 14 by means of a magnetically recording part 17. Graphic identification information ID from the graphic identification information storage circuit 19 is record on the film 14.

摘要： PURPOSE:To improve operability, by providing a magnetic coating part or the end of a film not being a picture recording part so as to record magnetically a start position signal or the like, thereby deciding an accurate read start position of the picture. CONSTITUTION:A photosensitive emulsion 7 is applied entirely to an area A of an X-ray fluorography roll film 4 with a picked-up picture 2 or a picture number 3 picked up thereupon and a magnetic coating part 5 is provided onto other area B on the film base 6. The magnetic coating part 5 may be provided only on one side not being at both sides in the film broadwise direction. Moreover, the width is selected to be a proper width not overlapped onto the pickup- picture 2 or the picture number 3. In recording a picture on the film, since the read start position signal and the ID or the like are recorded and read by a magnetic head, etc., the handling and operability are improved.

摘要： PURPOSE:To measure density accurately, by arranging a polarization converter, which converts linearly polarized light into circularly polarized light or elliptically polarized light, which is approximate to the circularly polarized light, at an arbitrary place on a light path for a light from a laser to a picture film. CONSTITUTION:A light beam is emitted from a laser A and converted into circularly polarized light or elliptically polarized light, which is approximate to the circularly polarized light by a 1/4 wavelength plate C in a converging optical system B. The diameter of the beam is converted into a desired beam diameter by a beam diameter converter D. Then, the light is converged by a condenser lens G and inputted to the surface of a picture film L, which is held by rollers H-K. The light beam, which has passed the film L, is split into two light beams having a large quantity of light and a small quantity of light by a beam splitter N in a light receiving optical system M and outputted to a light quantity detector Q. One beam is converted into a voltage by a photoelectric converter P and a current to voltage converter R. The other beam is converted into a voltage by converter Q and S. The voltages are inputted to a voltmeter U in response to the selection of a switch T. The voltages are measured as the quantity of light, and the density of the beam scanning part is obtained based on the quantity of light.
