A high-frequency heating apparatus comprises a heating chamber, a high-frequency generator, a waveguide, an antenna, a motor for rotating the antenna, and a stage (6) provided above and near the antenna to partition the heating chamber and made of dielectric. A rotary base on which an object to be heated is mounted is provided on the stage. A first magnet is provided to the antenna. A second magnet is provided on the rotary base at a place corresponding to the first magnet on the rotary base. By utilizing the magnetic coupling between the first and second magnets, the rotary base is rotated in synchronism with the rotation of the antenna. While maintaining the advantages of conventional antenna high-frequency heating apparatuses, the heating efficiency by grill heating or oven heating is enhanced, and minute heating uniformness is achieved.

The present invention provides a cleaning device and a cleaning performance maintaining method. By means of setting at least one of concave parts or convex parts arranged on at least a part of the surface of an elastic sheet facing to a cleaning blade between the cleaning blade and the elastic sheet, the surface of the cleaning blade is prevented from contacting with the surface of the elastic sheet.

An automatic packaging system for micro-injection-molded magnetic parts, including a feeding conveyor, a feeding mechanism for unqualified products, a feeding mechanism for qualified products, a packaging conveyor and a slide table; the packaging conveyor is arranged in parallel on one side of the feeding conveyor , the other side of the unloading conveyor is provided with unqualified product unloading mechanism and unqualified product unloading mechanism, the conveyer belt of unloading conveyor is provided with spaced grooves for holding micro-injection magnetic parts, the tail of packaging conveyor There is a sliding table at the end. The system is simple in structure, safe and reliable, and can automatically complete blanking, rejection of unqualified products and packaging of qualified products, which not only improves the efficiency of blanking and packaging, but also avoids surface contact of micro-injection magnetic parts.

The invention provides a permanent magnet suspension wing panel aeroelastic vibration generating set. The permanent magnet suspension wing panel aeroelastic vibration generating set comprises two support forms, namely, a double-side double support form and a middle single support form, a wing panel is supported by permanent magnet suspension; and an electromagnetic induction energy transformation type is adopted. Power is generated by means of aeroelastic vibration of a permanent magnet suspension support wing panel, and a mechanical elastic support element in a conventional wing panel aeroelastic vibration generating set design is removed, so that the problem of fatigue of a wing panel support element is solved fundamentally. A linear bearing is taken as a guide device for a support rod to perform ups and downs in conjunction with the wing panel, and a suspension annular permanent magnet is fixedly connected to the support rod, so that surface contact between the suspension annular permanent magnet and a cylindrical sleeve is avoided, and friction force of permanent magnet suspension support is lowered. The permanent magnet suspension support has a nonlinear rigidity feature, and the non-linear rigidity feature of the suspension annular permanent magnet can be changed by adjusting a distance between fixed annular permanent magnets at two ends of the cylindrical sleeve, so that the wing panel can perform chattering motion at a relatively low wind speed.
