Abstract: A phase synchronizing circuit for a time axis shift correcting circuit includes a closed-loop phase lock circuit of a phase comparator, a VCO, and a frequency division counter, for providing an output signal phase locked to a reference signal included in an input data signal. Hold circuitry, responsive to a hold instruction signal, is provided to hold the phase relationship of the output signal held just prior to the hold instruction signal for the duration of the hold instruction signal. The hold instruction signal is produced in response to a predetermined condition of the input data signal.

Abstract: A video processing system in which data obtained from sampling an input video format signal according to a first timing signal is written into a first memory according to the first timing signal. Data is read-out of the first memory according to a second timing signal having a frequency equal to N times that of a horizontal synchronizing frequency of the input signal, thereby obtaining data with no time-base fluctuation. M-samples of data from the first memory is then written into a second memory, and data from the second memory is read-out such that the read-out signal from the second memory has a different phase than that of the input video format signal. The system is operable for simultaneously stopping data being read-out of the first memory and data being written into the second memory for a period of time equal to R+kM samples of the input video format signal, wherein R is an integer remainder of N/M, and k is either a positive integer or zero.

Abstract: A video information playback system for playing the so called CLV disks which uses a digital video memory for enabling special playback mode operations such as the SLOW mode, the STILL mode, and the FAST mode. In order to simplify the construction of the system, a frequency of write and read clock signals used in the digital video memory is selected n times the horizontal synchronizing signal frequency. A time base servo control part of the system is controlled using a phase difference signal between a playback synchronizing signal and a reference signal whose frequency is 1/n time the frequency of the write and read clock signals. During a track jump operation for a special playback mode operation, a supply of the write clock signal and/or the read clock signal to the reference signal generator is stopped so that the phase difference is maintained constant before and after the track jump operation.

Abstract: Continuous fluorination of carbon is carried out by employing an apparatus for contact reaction of solid powder and reactive gas which comprises a horizontal reactor having a trough provided with weirs (e.g. height: 1 to 6 mm., interval: 5 to 30 cm.) and a vibrating means for vibrating the trough, and in which carbon particles supplied continuously are transported on the trough in a form of thin layer by the vibration of the trough while continuing the reaction by contacting efficiently the carbon particles with a fluorine gas. The contact reaction is efficiently conducted without accumulating the reaction heat to produce the fluorinated carbon in high yields, and the process is useful for the mass production. The apparatus is also useful for various contact reaction of a solid powder and a reactive gas.
