Title: Machining power supply device of electric discharge machine
Inventor: MURAI MASAO
IPC: B23H1/02
Filed: 2002-12-16
Abstract: <P>PROBLEM TO BE SOLVED: To prevent interruption of discharge in delay time up to rising of voltage impression from a main power supply circuit after detecting the discharge by restraining a leakage current.  <P>SOLUTION: A parallel circuit of a resistor 44 and a capacitor 45 is inserted in series into a voltage impression circuit to between electrodes between a work 1 and an electrode 2 from a sub-power supply circuit 4. Voltage of a sub-power supply 41 is impressed between the electrodes by turning on a switching element 42. When the discharge is generated, an electric current is made to flow via the capacitor 45, and the discharge is maintained. Even if a discharge current vibrates by floating capacitance and inductance, the discharge is not interrupted. Machining is performed by making a machining large electric current to flow by a main power supply 31 by turning on the switching element 32 by detecting the discharge. Since the leakage current can be held in a small leakage current by a current limiting resistor 44 up to generating the discharge by impressing sub-source voltage between poles, galvanic corrosion of the work is restrained, and sticking of an electrode material to a work machining surface can also be restrained.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

IPC: H01L21/205
Filed: 2002-05-07
Abstract: The method produces coherent dislocation-free regions from initially dislocated and/or defect-rich lattice mismatched layer grown on top of the substrate having a different lattice constant, which does not contain any processing steps before of after the lattice-mismatched layer growth. The process preferably uses in situ formation of a cap layer on top of a dislocated layer. The cap layer preferably has a lattice parameter close to that in the underlying substrate, and different from that in the lattice mismatched layer in no strain state. Under these conditions, the cap layer undergoes elastic repulsion from the regions in the vicinity of the dislocations, where the lattice parameter is the most different from that in the substrate. The cap layer is absent in these regions. When the cap layer has a lower thermal evaporation rate than the underlying lattice-mismatched layer, the regions of this lattice-mismatched layer containing dislocations are selectively evaporated at high enough temperatures, and only the coherent defect-free regions of the initially defect-rich lattice-mismatched layer remain on the substrate. In one embodiment of the invention, the defect-free regions are formed on the substrate with a size preferably tuned in the range of 30-1000 nm, depending on the annealing conditions, thickness of the cap layer, and the lattice mismatch. A device created by this method is also disclosed.
