摘要： A phase shift circuit comprises a variable phase shifter responsive to an externally supplied voltage to change the amount of phase shift, and a phase detector operative to detect a phase difference between input and output signals of the variable phase shifter and supply a voltage complying with the phase difference to the variable phase shifter. When the center frequency of the variable phase shifter is changed by reason of production errors and temperature variations to deviate the phase shift amount from a desired value, the phase detector controls the center frequency such that the phase shift amount can be fixed to the desirably predetermined value.

摘要： A method and system for file relocation is provided. A file relocation system is connected to multiple storage devices. The system obtains a number of times that each of a number of files stored on the multiple storage devices is requested simultaneously with a concerned file. The relocation system then classifies multiple files into multiple groups, such that groups of files simultaneously are put together into one group. Multiple files classified in to the same group are then relocated to a single storage device. The relocation system then switches a storage device not accessed for a certain period of time into a power-saving mode.

摘要： In a television receiver in which scanning for an incoming video signal is performed at a frequency n times as high as the input horizontal synchronous frequency by suitably controlling writing and reading on its video memory, the signals for writing and reading on the video memory unit are generated by a horizontal synchronization/deflection circuit. The horizontal synchronization/deflection circuit is arranged by having a clock generation/synchronous deflection circuit for generating reference signals to control the writing and reading on the video memory unit provided with a phase comparator such that a horizontal drive signal to drive a horizontal deflection circuit and a flyback pulse are brought in phase.
