Abstract: A recorder using an analog-to-digital converter for converting an input signal into a succession of digital words. The digital words are stored in groups with each group having a number of words corresponding to the number of recording elements arranged along a recording line. Each digital word in a group is compared with a digital signal representative of the position of a recording medium. Upon the detection of an equality between the compared signals, an energizing signal is applied to a corresponding one of the recording elements which energized state is maintained until the loss of an equality between the compared signals corresponding to a previously energized recording element. The recording lines are located transverse to the motion of the recording medium with a plurality of recording lines forming a recording frame for recording a predetermined portion of a time axis of the input signal.

Abstract: Recording and playback apparatus for recording visible representations on a recording medium having a uniform distribution of capsules containing a suspension of reflective, force-field responsive particles. A first recording means is arranged to direct an alternating magnetic field into the medium to selectively align the particles to produce a recorded visible representation while the aligned particles exhibit a substantially zero net remanent magnetic field external to the medium. A second recording means is arranged to direct a unidirectional magnetic field into the medium to selectively align the particles to produce a visible recorded representation while the aligned particles exhibit a net remanent magnetic field external to the medium. A magnetic playback head is traversed across the recording medium to detect the net remanent magnetic field indicative of the recording produced by the second recording means.

Abstract: A magnetic recording head for recording on a magnetically responsive recording medium is arranged to incorporate a core structure of high magnetic retentivity material with individual core members being magnetized by a respective winding to produce a magnetic flux through the magnetically responsive recording medium. A flux return path is arranged to distribute the magnetic flux in the return path to a flux density level which is ineffective to produce a recording on a recording medium and is arranged to provide a flux return path on the other side of the recording medium from the magnetic recording head. A common bias and reset winding is arranged on the core structure and is separately energized to normally bias the core structure to a magnetic state which is ineffective to produce a recording on the recording medium during the absence of a signal on the individual windings on the core members and to reset the core structure to a non-recording state after the core members have been placed in a recording state by a signal applied to the respective windings on the core members.

Abstract: A lens device traverses a predetermined portion of a light path between an external scene and an image plane on which an image of the scene is to be focused. A wobbulating mirror effects a rotation of the image on the image plane. A light detection device comprising a mask with apertures therein and a light responsive device, is positioned at the image plane. As the image is uniformly moved over the mask, the frequency characteristic of the output signal of the light detection device varies with the degree of sharpness of the scanned image. The high pass filter passes only the high frequency components of the output signal of the light detection device to a frequency-to-magnitude converter which, in turn, is connected to a peak detector circuit. The output of the peak detector circuit is related in time to the position of the lens at which the best focused image appeared at the image plane during the predetermined travel of the lens.

Abstract: A focus detecting system includes first and second lens devices for forming first and second auxiliary images of an object on first and second detector devices, respectively. Each detector device includes a corresponding plurality of linearly displaced light responsive elements. Before initiating a focus detecting function, a light diffusing device is positioned in the light paths ahead of the detector devices to effect substantially equal illumination of the detector devices. A balancing circuit connected to the detector devices or the a balancing charge representative of any inequality in the signals fuel to the corresponding light responsive elements. When the focus detecting action is initiated, the light diffusing device is removed and one of the lens devices moves with respect to its associated detector device to shift the light distribution pattern of the corresponding auxiliary image. The moving lens device is so coupled to a moving objective lens, which focusses a principal image of the object on a light sensitive film, that when the principal image is in focus, equal amounts of light will fall on corresponding light responsive elements of the first and second detector devices. The stored balancing charge is combined with the signals provided by the photo responsive elements during a focus detecting operation to provide compensated signals which are then processed to effect the termination of the movement of the objective lens when the principal image is properly focussed.

Abstract: A focus detecting system includes first and second lens devices for forming first and second auxiliary images of an object on first and second detector devices, respectively. Each detector device includes a plurality of linearly displaced light responsive elements. One of the lens devices is movable with respect to its associated detector device to shift the light distribution pattern of the corresponding auxiliary image in the direction of linear displacement of the light responsive elements. The movable lens device is so coupled to a movable objective lens, which focusses a principal image of the object on a light sensitive film, that when the principal image is in focus, the light distribution ppatterns of the first and second images will be correspondingly positioned with respect to the first and second detector devices, respectively. A reference signal of a predetermined frequency controls a switching circuit to compare the electrical signals from the light responsive elements in the first detector device, alternately, at the predetermined frequency of the reference signal, with electrical signals provided by first and second predetermined groups of the light responsive elements in the second detector array. Signals are thereby provided which are processed and phase-detected to provide an output signal representative of the direction that the objective lens is displaced from a focus position at which the principal image is in sharpest focus.
