摘要： A reproducing apparatus includes an equalizer for equalizing reproduced data, a clock generating circuit for generating a clock synchronized with the reproduced data, and a phase difference detector for detecting a phase difference between the reproduced data equalized by the equalizer and the clock. The clock generating circuit receives an output from the phase difference detector as a control signal, and generates a clock of frequency according to the output from the phase difference detector. The equalization characteristic of the equalizer is controlled by the control signal of the clock generating circuit. With this arrangement, it is possible to generate a clock which follows a variation in the frequency of the reproduced data, and it is also possible to realize an optimum equalization characteristic according to the variation in the frequency of the reproduced data.

摘要： A video signal processing apparatus for processing a video signal includes a plurality of series-connected signal processing circuits. A plurality of timing control circuits for respectively controlling the plurality of signal processing circuits in accordance with a reference signal are provided. At least one of the plurality of timing control circuits inputs a timing signal conforming to the reference signal, and delays the passage of the timing signal therethrough by a time interval corresponding to a delay time of the video signal generated by the corresponding signal processing circuit and outputs a delayed timing signal. Consequently, it is possible to minimize a change in the timing control circuits, that is, a change in the overall apparatus, caused by the partial change in the design of the signal processing circuits.

摘要： A method and apparatus for providing to an anti-rust treatment a peripheral portion a shell such as is associated with a brake booster and which comprises a pair of cylindrical members disposed in abutting relationship with each other and fastened together by a staking operation which occurs by applying a shearing action to the periphery of the abutting members at a plurality of locations. The substantially cylindrical shell is held at an angle with respect to the horizontal, and then driven for rotation. A vehicle containing an anti-rust paint is disposed below the rotating shell, and the shell is positioned so that its axis of rotation does not intersect the vessel. As the shell rotates, the shear-staked peripheral portion of the shell is successively brought into dipping relationship with the paint.
