An apparatus for carrying out a fine servo control and a rough servo control with respect to the rotation of a motor for rotating a recording medium in accordance with information recorded on the recording medium. A fine servo signal is generated on the basis of a reproduction clock, filtered by a first filtering device, and used for the fine servo control. A rough servo signal is generated on the basis of a frame synchronizing signal, filtered by a second filtering device, and used for the rough servo control. The first filtering device has a first frequency band, and the second filtering device has a second frequency band. The upper limit of the second frequency band is lower than that of the first frequency band.

A gain controlling apparatus is provided with: an adjusting device (,) for adjusting a gain of a generation signal, which is generated on the basis of a light reception signal obtained by receiving a reflection light of a light beam from an information recording medium (,); and a detecting device (,) for detecting whether or not the generation signal is generated and outputting a detection signal when the generation signal is generated. The gain controlling apparatus is also provided with a controlling device (,) for controlling the adjusting device to increase the gain by a predetermined value set in advance when the detection signal is not outputted by the detecting device.

High speed plating apparatus in which a cylindrical electrode structure has fitted into it a metal tube. The metal tube has a higher melting point than the electrode, is corrosion resistant to plating liquid and protects the inner surface of the electrode.

High speed plating apparatus

This invention relates to a method and apparatus for manufacturing seamless material-filled capsules characterized by the fact that a capsule filler material, a sol solution and a water-insoluble solution in the form of a continuous jet are fed from a triple orifice of the same core into a stream of hardening solution, the spherical drops consisting of the above mentioned three layers are completed due to their interfacial surface tensions, then said water-soluble solution of said outermost layer is caused to strike several interrupting plates to have said water insoluble layer destroyed and separated from the sol solution as a second layer to react said sol solution with said hardening solution at this instant for forming a water-insoluble film and the diameter the wall thickness of said spherical drop can be changed easily by modifying the flow speed of the hardening solution and the diameter of said orifice.
