摘要： Coding section 205 recodes decoded data stored in decoded data storage section 204, data conversion section 206 converts data “0” and “1” output from coding section 205 to “1” and “−1” respectively, sum-of-product calculation section 207 multiplies the data output from data conversion section 206 by the demodulated data (soft decision value) stored in demodulated data storage section 201 and then calculates the sum of the products for 1 TTI and stores the sum-of-product result for each data rate, data rate decision section 208 decides the data rate corresponding to a maximum value of the sum-of-product results as the data rate of the demodulated data. This makes it possible to improve the accuracy of data rate decision and reduce decoding errors of a received signal.

摘要： An electron-beam generating device, in which a number of cold cathode elements are matrix-wired, as well as a method of driving the device, is applied to an image forming apparatus. Statistical calculations are performed in advance with regard to a required electron-beam output, and loss produced in the matrix wiring is analyzed. Drive signals are corrected by deciding optimum correction values based upon the analytical results. As a result, when rows of the matrix are driven successively row by row, the intensity of the outputted electron beams can made accurate for any driving pattern.

摘要： A method and apparatus for driving an electron source in which a high-quality image display is presented by correcting a non-uniform effective current distribution caused in cold cathode elements by leakage current. A digital video signal enters a shift register where a serial-to-parallel conversion is made for each line of an image based upon a shift clock signal. One line of the image data that has been subjected to the serial-to-parallel conversion is latched in a latch circuit and then applied to a voltage modulating circuit. The latter voltage-modulates the input data and sends the modulated signal to a voltage/current converting circuit. The latter converts the voltage quantity to a current quantity, which is applied to each of the cold cathode elements of a display panel through respective column terminals. A voltage V1 is applied to the selected row wire, and a voltage V2 (V2≠V1) is applied to all other row wires, for controlling the leakage current.

摘要： In order to prevent voltage drops across the wiring resistances in a multi-electron source having a plurality of electron emitters wired in the form of a matrix through a plurality of data wiring layers and a plurality of scanning wiring layers, a constant current signal is output to each data wiring layer. At this time, each non-selected data wiring layer tends to be set at a high impedance and vary in potential, resulting in an abnormal turn-on operation or an electron orbit shift. A driving circuit for solving this problem is provided. A switch for switching a constant current output unit for outputting a constant current regardless of the impedance of a signal output destination, and a constant voltage output unit for outputting a constant voltage regardless of the impedance of a signal output destination is connected to each data wiring layer. For example, a constant-current circuit (17) as a current output unit always outputs the same current (I1 to In) to a switch (30). A pulse width signal (PW1 to PWn) from a pulse-width modulation circuit (7) serves to switch the mode of outputting a current (I1 to In) to a data wiring layer (Dy1 to Dyn) and the mode of fixing a data wiring layer to voltage GND.
