摘要： A digital device generates a local frequency and phase signal adapted for the conversion of one of a plurality of codified signals into binary code. The received codified signals are continuously stored in a shift register which is able to contain the signals received in a predetermined period at a time. The output of the shift-register addresses a memory. At predetermined instances of time the memory produces a control word which is input to a counter dependent on the phase of the received signals stored in the shift register. The counter activates output signals at predetermined instances of time in order to produce a local signal in synchronism with the received signal.

摘要： The apparatus can deal with graphs obtained as a computer output and comprises recording means controlled by a computing unit in response to the generation of each point of the graphs for recording in a memory an indication of its location in the graphs, addressing means for addressing said recording means so as to record the subsequent location indications being recorded adjacent and in the same order of the representation of the points made by said displaying or plotting means, and shifting means conditioned by said addressing means when the recording of a point is addressed for causing the shifting in said memory of the indications of all points following said recorded point in said order. The graph so recorded is plotted under the control of means which reads said memory in sequence. The memory is organized in cells, each one adapted to receive at least one of a group of points of a predetermined subarea of the plot. Each cell, when recording no points, is adapted to record a number indicating a plurality of blank subareas comprised between two subareas having at least one point recorded in the memory, whereby the blank subareas are recorded in compressed forms.Partial images are recorded with compacted record of blanks and are transferred to a disk memory. In order to be plotted all the partial images are extracted in parallel and, upon decompacting, the blacks are compounded in a printing buffer so as to enable a point printing head to plot the entire image in a single scanning of the paper.

摘要： An angular position transducer for a rotating member comprising a notched disc connected to said member, an opto-electronic pair for sensing the angular position of said disc and a supporting shell for said pair which is fixable on the support of the rotating member coaxially to said member. The disc is fixable directly to the rotating member at a predetermined position with respect to the shell, and comprises a thin flexible lamina guided on its periphery by a guiding element adjacent to the notches. The flexibility of the lamina compensates for any disalignment and axial displacement of the rotating member. The position signal is periodic and is sent to the terminals of a reference resistor. A control circuit modifies the value of the resistor in order to stabilize the peak value of the position signal within predetermined narrow tolerance limits.

摘要： An electrophotographic copying machine having duplexing mode of operation and first and second selectively enabled sheet supply stations. The first supply station has a feeding device which turns the copy sheet to be fed upside down before delivering it to the conveyor moving the copy-sheet toward transfer station. In the duplexing mode of operation sheets fed from the second station are one side imaged along the copy-sheet path and are collected in the first section. Then one side imaged copy sheets are fed from the first supply station and are imaged on the other side along the copy-sheet path. A storage tray with adjustable stops is provided in said first supply station to handle copy sheets of different formats.

摘要： In a computer wherein a central processor and at least one peripheral controller have access to a memory, this latter is divided into two simultaneously accessible zones, namely a private zone accessible by the processor and a direct access zone accessible both by the processor and by the peripheral controller. A logic unit synchronizes the controller's access to the direct access zone with the processor's access to the private zone, the controller's access being delayed, if necessary to occur simultaneously with the processor's access. The peripheral controller's access is thereby achieved without interruption of processor operations.

摘要： A dot matrix printing device for electronic calculator comprising a plurality of electrically heatable dots of an insulating plate aligned therebetween and spaced according to a constant pitch to print the digits of the calculator amounts. A symbol dot is located adjacently to the terminal digit dot which prints the least significant digit of the amount, aligned with the other dots of the plurality. The symbol dot is spaced from the terminal digit dot by a distance greater than the constant pitch of the other dots and prints the explanatory symbols of the amounts leaving a blank between the digits and the symbols of the amounts.

摘要： In an apparatus for recording binary information on a flexible magnetic disk, a plate, is provided connected to an electric motor, for rotating the disk, and a spiral guide is formed on a first surface of the plate for moving a recording head radially with respect to the disk, in synchronism with the rotation of the plate and the disk. The improvement comprises an electronic circuit, which controls the angular speed of the motor, and quickly accelerates the motor, when the last binary information has been recorded on the disk, for shortening the time taken by the head to return to the rest position.

摘要： The operative memory of the computer is of the MOS type and is cyclically refreshed under the control of logic circuits, in turn controlled by the timing unit during the microinstructions decoding. Particularly, every machine cycle in which an odd microinstruction is fetched, a row of memory locations is addressed for being refreshed during the same cycle, before the next following machine cycle is started, thus preventing any overlapping of refreshing operation with the CPU operation on the memory.
