摘要： A circuit for generating a tracking error signal is provided. The circuit includes a digitized circuit, a short signal removing circuit and phase comparator. The digitized circuit receives first and second pick-up signals outputted from a pick-up head, and respectively compares the first and the second pick-up signals with a reference signal to obtain a first digital signal and a second digital signal. The short signal removing circuit is used for removing pulses in the first and the second digital signals, wherein the pulse width of the removed pulses are shorter than a preset time, and the first and second digital without the removed pulses are respectively served as a first determining signal and a second determining signal. The phase comparator receives the first determining signal and the second determining signal for outputting the tracking error signal according to a phase difference between the first and the second determining signals.

摘要： A data recovery device including a filter, a tilt detection unit, a tilt cancellation unit and a data conversion unit is provided. The filter filters a radio-frequency data stream to generate an original data stream. The tilt detection unit synthesizes a tangential push-pull data stream by employing a first to a fourth data streams, and generates a tilt direction signal according to symmetry of a curve composed by the tangential push-pull data stream. The tilt cancellation unit detects a plurality of rising areas and falling areas of the original data stream, and reconstructs a plurality of data points corresponding to the rising areas or falling areas in the original data stream so as to generate a tilt repair data stream. The data conversion unit recovers the tilt repair data stream to a modulation signal.

摘要： A process for producing an ethylene vinyl acetate insole involves weighing molding compounds for manufacturing the ethylene vinyl acetate insole. The molding compounds are mixed and rolled by means of a roller so as to form a sheet material. The sheet material is cut into a plurality of elongated strips. A predetermined amount of the strips are placed into a first mold unit, which is heated and pressurized so as to form a partially foamed insole. The partially foamed insole is placed into a second mold unit, which is heated, pressurized, and cooled so as to form a completely foamed insole. The completely foamed insole is trimmed to form a finished ethylene vinyl acetate insole.
