This paper mainly discussed the design and the implement of the motorcycle CVT working characteristics system from three aspects: data collection, data storing and data displaying.

The design of a data display system on the guidance radar monitor with 8098 single-chip computer is demonstrated.

A New Circuit about Digital Display of On Off signal;

The electrical control part of RX-300 hot spinning machine consists of five sys- tems: (1) mid-frequency induction heating system; (2) main shaft transmission system ; (3) roll wheel feeding system ; (4) hydraulic operating system ; (5) system for working para- meter measurement and digital display.

This paper introduces the reasons,the kind of the inerferance in the digital displaying device of inverter welding and the measures of anti interferance.

The digitaldisplaying technique for voltage revolu- tionises the traditional DC stabilizer,makes the stabilizer high efficient,low consuming,stabilizing range wide,digital displaying,voltage regulating continuous,worldwise adaptable and competitive.

The step adjustment of the generator output frequency and amplitude is controlled by a single chip microcomputer in order to realize the digital display.

This paper introduces a circuit design of digital display answering device by using monolithic machine,its operating principle as well as circuital programming.
