摘要： An improved ultrasonic imaging apparatus utilizing ultrasonic waves for obtaining an image of a target object which comprises a transmitting transducer radiating ultrasonic waves whose direction of radiation varies depending on the input frequency, a receiving transducer receiving reflected acoustic waves from a target plane, a frequency analyzer converting the output signal of the receiving transducer into a signal representing the position of the target plane on the basis of the frequency and the position of the received acoustic waves on the receiving transducer, and an image display unit displaying the output signal of the frequency analyzer. In the apparatus, in order to obtain a three-dimensional image including depthwise image information in addition to plane image information of the target object, the frequency analyzer is constructed so that a plurality of image information successively obtained from a plurality of target planes of different depths can be converted into signals representative of different depths to be displayed in superposed relation on the display unit.

摘要： 1,051,421. Cathode-ray tube displays. HITACHI Ltd. March 3, 1964 [April 3, 1963], No. 9033/64. Heading H4T. Signals (a1, Fig. 2) derived via a microphone A1 (Fig. 1, not shown), held in the region of the trachea and equalized in a circuit A2 (waveform a2) are displayed on the screen of a cathode-ray tube D against a time base which is triggered at a predetermined instant by a pulse (c). The latter is produced by counting in a circuit C a selected number of the pulses of a train (b1) produced in circuit B1 and the timespacing of which is equal to the period of the cycles of waveform (a1). Additionally, a circuit B 2 is employed to convert pulse train (b1) into a pulse train (b2) having amplitude variations corresponding to the variations in timespacing of (b1), i.e. amplitude variations corresponding to variations in pitch (frequency) of waveform (a1) and such variations are also displayed on the tube, e.g. by employing a dual beam tube. The input to circuit B1 may be replaced by the output of a reference generator E producing frequency modulated waves for calibration purposes. The tube preferably has a long persistence to facilitate direct visions.

摘要： 1,176,407. Recording and playback. HITACHI Ltd. 27 Sept., 1967 [28 Sept., 1966; 16 Dec., 1966; 7 June, 1967], No. 44074/67. Heading G5R. Intended particularly for use in dictation, playback apparatus is controlled by means which responds to a break in the recorded signal to interrupt the playback for a length of time which depends upon the length of the immediately preceding playback period. The length of the pause is controlled by means of a capacitor (16, Fig. 1, or 43, Fig. 5) which is charged during playback and discharged during a pause, or by means of a cam (68, Fig. 7) which is driven in one direction during playback and in the opposite direction during a pause.
