High-frequency heating apparatus
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.

A sacrifice layer 36 is exposed through a chemical charging port 31 so that the sacrifice layer 36 and sacrifice layer 35 are etched and removed by an etchant introduced from the chemical charging port 31. Since the surface of an Si substrate 22 is exposed to an etching window 34 corresponding to the removed portion of the sacrifice layer 35, the Si substrate 22 is crystal anisotropically etched below the etching window 34 to form a cavity 23. In contrast, in a space corresponding to the etched and removed portion of the sacrifice layer 36, since the surface of the Si substrate 22 is covered with a protective film 32, the Si substrate 22 is not etched to form a bent hole 26 therein. The cavity can be formed in the semiconductor substrate by an etching process from the surface side. Moreover, a bent hole having a great acoustic resistance can be easily formed.

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.
