摘要： A recording apparatus receives a video signal containing a horizontal sync signal and a data signal comprised of a given number of image bit data arranged within each horizontal scanning period, and stores the number of image bit data in synchronization with the horizontal sync signal. A voltage-controlled oscillator produces in synchronization with the horizontal sync signal a frequency signal having a frequency higher than that of the sync signal. A divider frequency-divides the frequency signal by a given factor to produce a number of sampling pulses corresponding to the given number of image bit data. A data sampling circuit receives the data signal for sampling therefrom the number of image bit data in response to the corresponding sampling pulses to thereby write the image bit data into memory. Another divider frequency-divides the frequency signal by the product of the given factor and the given number to produce a feedback signal. A comparator compares the phase of the feedback and sync signals with each other to produce a control signal effective to maintain the VCO to continuously produce the frequency signal synchronized with the horizontal sync signal.

摘要： A color hard copy apparatus converts an analog video signal of a still picture frame displayed on a color graphic display into binary video data to obtain a multicolor gradation picture. A single analog-to-digital converter samples the analog video signal a plurality of times at respectively different threshold levels, each threshold level being maintained constant during the sampling of the entire picture frame, to convert the analog video signal into corresponding binary video data. The binary video data are written in a picture memory at predetermined write-in addresses according to a predetermined multicolor gradation picture program, such as an organized dither program or a density pattern, and the binary video data are read out of the picture memory according to the predetermined multicolor gradation picture program to obtain binary picture data signals for use in printing a high-quality multicolor gradation picture corresponding to the desired picture frame displayed on the color graphic display.

摘要： An interface circuit of video signal hard copy apparatus for optimizing a phase of a sampling clock to an image signal. A delayed signal of a video sync signal is employed for a reference input signal of a sampling clock generation circuit. The delay quantity of the video sync signal is arbitrarily set by a control circuit. The delay quantity corresponding to the point of change of sampled data is detected by a CPU circuit according to the sequential comparison with some of the sampled data of an image signal in the plural delay quantities. A stable sampling can be attained even for a high frequency video signal exceeding 100 MHz by setting the optimum delay quantity according to the detected delay quantity.

摘要： This invention relates to a rocking device of a folding knife, which makes folding work easy and reduces the play between a blade and a holding handle. A round hole(21) and anchor notches(211), (212) are formed at the root portion of the blade(2) and a support sheet portion(42) is accommodated in the round hole(21) through a substantially criss-cross anchor plate member(41) and a compression spring(5), and the anchor member(41) is fixed to a drum sheet portion(11) of the holding handle(1) by fixing pins(3). When the back of the root portion of the blade(2) is pushed under the open state of the knife, the blade(2) deviates against the force of the spring(5) so that an anchor projection(411) of the anchor sheet member(41) that has been meshed with an anchor notch(211) of the blade(2) is disengaged from the notch(211) and the blade(2) is now able to rotate with respect to the holding handle(1). When the blade(2 ) is rotated clockwise under the folded state of the knife, the anchor projection(411) of the anchor sheet member(41) slides over an inclination formation portion(2121) of the anchor notch(212) so that the blade(2) can opened.
