摘要： A memory comprises a multilayer Langmuir-Blodgett film (1) in which each layer (2) is capable of carrying a charge. A photo-injector layer (D) is located on one side of the film for introducing charges into the film in a time sequence which corresponds to the information to be carried. Voltage source (6) is provided for applying a voltage between the faces of the film to cause the charge carried by any layer to be transferred to the adjacent layer. The sequence of charges carried by the film may be read out by a photon-emitting electron arrival detector (F) on the opposite side of the film, or by a method of current differentiation. The film (1) is preferably formed of a polydiacetylene.

摘要： An optical read apparatus for reading a disc-shaped record carrier. A read element is mounted on an adjusting member by means of which the read element is radially movable. Moreover, there is provided a deflection element for correcting the radial position of the scanning spot. In order to enable an arbitrary information unit on the record carrier to be read with a short searching time, the drive of both the adjusting member and the deflection element is controlled. In order to enable the adjusting member to be moved in a rapid and controlled manner there is provided a position indicator, which indicates the instantaneous radial position of the read element. Moreover, there is included a correction circuit which eliminates the adverse effect of inaccuracies in the position indicator on the searching time.

摘要： An optical data recording system in which during recording the writing beam is made to move at the same velocity as the recording medium whereby motion blur is minimized or reduced. Movement of the writing beam at the same velocity as the recording medium is achieved by supplying a constantly varying frequency RF signal to an acousto-optic device which deflects (diffracts) the writing beam in accordance with the instantaneous frequency of the RF signal. The acousto-optic device can also be utilized to amplitude modulate the writing beam.

摘要： A storage disk comprising at least one data track which is composed of spiral-shaped turns or concentrical turns, the data being arranged in the form of data blocks on the turns so that between the data blocks alternately a guide segment or a blank segment is present. The lengths of the unit, measured in angular degrees, consisting of data block and guide segment and the unit consisting of data block and blank segment are substantially the same and are chosen so that the same number of units is accommodated in each turn. The spirals are sub-divided into sectors which contain only data blocks or only guide segments or blank segments. In each sector containing guide segments the radial distance between these segments is substantially twice the distance between the data blocks in each sector containing data blocks. The invention also relates to a device for writing and/or reading data of a rotating disk as described, comprising a light deflection system which notably includes a slow light deflector and a fast light deflector, the latter deflector scanning the guide segments.

摘要： A detector circuit for MOS/LSI integrated circuit devices comprises a series transistor which has a sense clock applied to its gate and a gated capacitor connected between the gate and a sense node. The sense node and an input node may be precharged to a level at or near the supply. During the sense clock, the input and sense nodes are shunted together by the series transistor. If at the logic level of the supply, the gated capacitor is off and does not affect the circuit; if the input node decays toward the other logic level, the gated capacitor is on and the trailing edge of the sense clock causes the sense node to be switched to a full logic level.

摘要： A randomly accessible memory display is disclosed wherein a latching memory panel can be placed in direct optical contact with the triggering electroluminescent panel having a similar matrix. Once the glowing light from the trigger panel shines on the photosensitive resistive layer providing positive feedback, the corresponding region in the latching memory panel is latched. In accordance with the invention, a technique is disclosed for electrically reading the latched state in any one cell. This is done by selectively propagating a high frequency sinusoidal interrogation signal through each of the Y axis lines connected to the cells and measuring any phase alteration in each of the X axis lines connected to the cells, for each Y axis line interrogated. Since the resistance of the photosensitive resistor for a particular latching cell is altered if that cell is emitting light, the impedance of the cell is changed, thereby introducing a phase shift to the interrogation signal. The detection of the phase shift indicates whether the selected cell is latched in its light-emitting or light-extinguished state.
摘要翻译：公开了一种可随机访问的存储器显示器，其中可以将锁存存储器面板放置成与具有相似矩阵的触发电致发光面板直接光学接触。一旦来自触发面板的发光的光照射在提供正反馈的光敏电阻层上，则锁存存储器面板中的相应区域被锁存。根据本发明，公开了一种用于电读取任何一个单元中的锁存状态的技术。这是通过选择性地传播高频正弦询问信号通过连接到单元的Y轴线中的每一根，并且对于所询问的每个Y轴线，测量连接到单元的每个X轴线中的任何相位变化。由于如果该单元发光，光敏电阻器对于特定的锁存单元的电阻会改变，所以单元的阻抗发生变化，从而将相移引入询问信号。相移的检测指示所选择的单元是否被锁定在其发光或熄灭状态。

摘要： A close-packed magnetic bubble propagation device includes a pattern having a plurality of propagation elements positioned in at least four adjacent rows. These elements are spaced to provide a period or spacing of bubbles in these rows of less than three bubble diameters. Upon application of a rotating in-plane field to the elements, bubbles in adjacent rows move in opposite directions. A preferred embodiment of this propagation device has at least two storage loops which contain at least four adjacent horizontal rows of propagation elements. A preferred device utilizing this pattern has at least two storage loops and an access path which passes through each of the loops. An electrical conductor is associated with the propagation elements in the access path so that the passing of a current through the conductor together with the application of an in-plane rotating field to the elements causes bubbles associated with the elements in the access path to move along the access path. Preferably, the pattern is surrounded by an array of confinement elements which confine the bubbles to the storage loops and the access path.

摘要： In an optical memory device, such as an optical video disk, an injection laser is used as the source of the light, as the detector of the light reflected from the memory element and as the detector for controlling the proper focus of the light on the memory element. The light reflected from the memory element is fed back into the injection laser and variations in certain characteristics of the injection laser, such as the optical output at constant current, the electrical current through the laser at constant voltage and the voltage drop across the laser at constant current, are used to read the memory device and to maintain the focus.
