摘要： In order to image an object larger than a field of view for observation, imaging is effected by dividing it into several times and pictures thus imaged are synthesized to constitute a whole image. In order to image several times, only a detecting unit is moved and an X-ray source is substantially fixed with respect to the object. Images thus obtained include a common part of the object and are joined so that the common part are overlapped on each other. In case where an image pick-up tube is included in the detecting unit, the image pick-up tube is made operable, after a period of time necessary for attenuation of microphonic noise has lapsed, measured from a point of time where the detecting unit has been stopped.

摘要： An image input apparatus including a camera tube having a photoconductive layer onto which an optical image is to be projected, a cathode for emitting an electron beam for scanning the photoconductive layer, a control electrode for controlling a beam current of the electron beam emitted from the cathode in accordance with a control voltage, and a mesh electrode having a frame, the apparatus further including a deflecting circuit for periodically deflecting the electron beam to scan the photoconductive layer. The deflecting circuit periodically deflects the electron beam to scan an area outside a restricted scanning area determined by the frame of the mesh electrode. A beam current control circuit is further added, if necessary, for generating a control voltage and applying the control voltage to the control electrode to control the beam current of the electron beam such that the electron beam does not collide with the frame of the mesh electrode during a period in which the electron beam scans the area outside the restricted scanning area.

摘要： An X-ray television apparatus in which an X-ray image which is obtained by an X-ray image intensifier is converted to an electrical signal by a television camera. This electrical signal is converted to a digital signal and stored into an image memory, and the angiographic imaging can be performed due to a differential process of data between two X-ray images. Either one of first, second, and third operating modes in which the scanning periods and the numbers of scanning lines of the television camera differ and a fourth operating mode to obtain the X-ray images by a further low X-ray dose and to simultaneously monitor the X-ray images can be selected. Thus, proper time resolution and spatial resolution according to a desired purpose can be obtained and the beam current of the image pickup tube of the television camera which is optimum in each operating mode is set.

摘要： A visual travel route indicating apparatus, for use in an automotive vehicle or the like, including a distance sensor for detecting a current distance of travel of the vehicle, a gas rate sensor for detecting a current azimuthal deviation generated by the vehicle during a turning motion, a thermostatic control chamber for enclosing the gas rate sensor hermetically from external temperature fluctuations, and a signal processing unit for arithmetically obtaining a current location plotted on two-dimensional coordinates per a given unit travel distance of the vehicle from the outputs of the two sensors and storing the thus-obtained location data in sequence so as to be read out subsequently for a continuous visual indication of a current locus of the vehicle on a display. The power supply to the thermostatic control chamber is optimally controlled in conjunction with the on/off state of the ignition switch of the vehicle. The visual indication of a current travel route of the vehicle is inhibited until the atmospheric temperature of the thermostatic chamber reaches a desired constant level, whereupon the offset adjustment of the gas rate sensor output is automatically normalized so as to present a precise visual indication of the vehicle's travel route on the display. Further, the occurrence of an abnormal temperature within the atmosphere of the thermostatic control chamber is detected so as to provide a warning to a driver of the vehicle.
