Abstract: A time-base error correction circuit for use in a video disk player, video tape player, or the like, with which all residual time-base error is eliminated. A detector circuit detects the amount of residual time-base error between the reproduced video signal and a write clock signal. A variable delay circuit disposed prior to a memory in which the video signal is stored adjusts the delay of the reproduced video signal accordingly.

Abstract: A pickup control device for a data reading device in which, for fast or slow reproduction modes, a slider motor is forcibly driven to change the relative position of the pickup and the disk in a radial direction of the disk after which the pickup is set to a normal or center position thereof. A slider motor for changing the relative position of the pickup and the disk is driven in response to a fast or slow reproduction instruction and a position signal representative of the position of the pickup is produced with which a tracking servo loop is opened for a predetermined period of time during which the pickup is returned to its normal position. With this construction, the pickup is prevented from returning to a first track from a second track to which it has jumped through a scratch or the like.

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.

Abstract: A synchronous control device according to the present invention completes an origin matching between a master section and a slave section without causing a phase difference even when a deceleration device is employed in the master section or in the slave section so as to perform an accurate synchronous control. The synchronous control device constantly detects the phase of a shaft of a master electric motor by a phase detector of the master electric motor according to the outputs of a master rotary encoder, and the phase of a shaft of the master machine by a phase detector of the shaft of the master machine according to the outputs of a master rotary encoder and an origin detector of the shaft of the master machine. In the same manner, the phase of a shaft of a slave electric motor is constantly detected by a phase detector of the slave electric motor according to the outputs of a slave rotary encoder, and the phase of a shaft of a slave machine is constantly detected by a phase detector of the shaft of the slave machine according to the outputs of a slave rotary encoder and an origin detector of the shaft of the slave machine. Then a first phase deviation between the shaft of the master machine and shaft of the slave machine by a first phase deviation detector, and a second phase deviation between the master electric motor and the slave electric motor by a second phase deviation detector for the electric motors are calculated. After an origin between the shaft of the master machine and the shaft of the slave machine is matched based on the first phase deviation, continuously an origin between the master electric motor and the slave electric motor is matched based on the second phase deviation so as to perform the synchronous control.

Abstract: A scanning method for high-speed reproduction of video data from a recording disk, whereby scanning is executed as a sequence of track jump operations, in which the data detection point of the pickup is caused to jump across tracks of the disk, alternating with intervals of play operation in which data are read from the disk. During each interval of play operation, data obtained from the disk are written into a memory, and thereafter are repetitively read out from the memory to produce an output video signal, until being updated during the next play interval. A display image that is free from noise and disorder is thereby obtained during scanning operation.

Abstract: A system for detecting an inversion of burst phase of a video signal, includes a reference color subcarrier signal generator for generating a reference color subcarrier signal whose frequency is equal to the frequency of the color burst signal of the video signal, and a phase comparator for comparing in phase the color burst signal of the video signal and the reference color subcarrier signal. When the level change in an output signal of the phase comparator exceeds a predetermined reference level, the system produces an indication signal indicating that the burst phase of the video signal is inverted.
