摘要： An electric discharge is generated between an electric discharge surface treatment electrode and a wire electrode, and an electric discharge surface treatment material is stuck on the surface of the wire electrode by the energy of the electric discharge. An electric discharge is then generated between a work piece and the wire electrode on which the electric discharge surface treatment material is stuck, and a surface modified layer is formed on the surface of the work piece by the energy of the electric discharge.

摘要： An electrostatic microactuator, known as a “Scratch Drive Actuator” or SDA, is based on a collective set of distributed elementary SDAs of small size that are associated with one another and that integrates a large number so as to allow the addition of the forces generated by each of the SDAs in the collective set. An external mechanical prestress, formed by a homogeneous external pressure in the form of a bias voltage applied at rest to the associated SDAs, is applied to the SDAs to allow a superposition of the forces generated by the associated SDAs. This is done while communicating to an external load the entire driving force emanating from the collective behavior of the SDAs. The electrostatic attraction forces established by the bias voltage are used to calibrate an individualized prestress for each actuator involved in the collective set. Such an electrostatic microactuator forms part of an active three-dimensional microcatheter, as one possible application, that can be used in a blood vessel.

摘要： The invention relates to a method of electrolytically machining the surface of a workpiece by applying positive and negative electric current pulses alternately and repeatedly across the workpiece and a tooling electrode located oppositely in a neutral electrolyte so as to keep a predetermined gap therebetween, wherein the time interval from a negative pulse to a positive pulse is shorter than that from the positive pulse to the next positive pulse. The invention also relates to an apparatus for attaining the method comprising: a device for supporting the workpiece in an electrolytic machining tank; a device for supporting an electrode opposite to the workpiece so as to keep the gap; a power supply means for repeatedly applying across the workpiece and the electrode an electric current waveform wherein its polarity changes alternately and the time interval from a negative pulse to a positive pulse is shorter than that from the positive pulse to the next negative pulse; a device for supplying an electrolyte between the workpiece and the electrode; and a control system for controlling the workpiece fixing device, the electrode supporting device, the power supply means and the electrolyte supplying device.

摘要： A method and a device for finishing the cut surface of a work which is cut from a metal blank by a wire cut discharge process. The work and the waste piece of the metal blank are positioned in the same condition as just after the process. Electrolyte is fed through a clearance between the work and the waste piece and, at the same time, current is caused to flow from the work to the remainder. This subjects the cut surface of the work to electrolytic treatment to thereby make it smooth while removing oxide films and degenerated surface layers therefrom.
