摘要： In order to reduce radio interference jamming in the same channel exerting from an adjacent broadcasting area when a digitized image signal of, for example, high-definition television utilizing an idle channel in ground broadcasting of television is transmitted, a digital string such as a binary coded image signal is thinned out every predetermined digital period so as to be divided into two groups. Continuous digital strings of two series are formed by converting clock rates of the respective groups and converted into multi-value digits. Intermediate carriers are then modulated with the digital signals of the two series having their requisite bands compressed through quadrature modulation to form modulated carriers, and the modulated carriers are transmitted in bands of two divisional channels which escape from adjacent video and voice carriers, the power of which is responsible for the radio interference in the same channel. The carriers are subsequently received for reconstruction.

摘要： A method for re-tracing an end point of an image by an image processing device for converting the line images of the image data into vector data in a semi-automatic way by tracing plural line images and converting them into one vector data. The method for re-tracing the end point of the image involves tracing the line images by transferring the tracing points on the line images and continuing the previous trace processing for re-tracing the line image which follows by waiting for an instruction to re-trace from the input unit and entering the instruction to re-trace the image specified for re-tracing when the tracing point has reached the end point of the line image whose tracing points have been traced.

摘要： In a semiconductor memory device having a sense amplifier for amplifying a potential difference between a pair of regular bit lines, the memory device further comprises a dummy bit line having a load capacitance equal to that of each of the pair of regular bit lines, a dummy memory cell having a bit line drive capability equal to that of the regular memory cell, a precharging circuit for precharging the dummy bit line, a selecting circuit for simultaneously selecting the regular memory cell and the dummy memory cell, a dummy bit line potential sensing circuit for sensing that the potential of the dummy bit line is changed from a precharge potential by a predetrmined potential when the dummy memory cell is selected by the selecting circuit, and a sense amplifier control circuit for receiving an enable signal which enables operation of the sense amplifier, and a sensed signal from the dummy bit line potential sensing circuit, to determine an operation period of the sense amplifier, in response to both the enable and the sensed signals. When the output data is determined by the sense amplifer, an output logic level of the level sensor is inverted, and the sense amplifier is disabled. The sense amplifier is kept disabled until the next clock signal is generated, and no feedthrough current flows during this period, decreasing wasteful power current consumption.
