An electric discharge machine to process a work piece includes a plurality of electrodes, and a plurality of discharge power supply units. The plurality of electrodes generate a plurality of discharges with the work piece, respectively. The plurality of discharge power supply units apply voltages for the plurality of electrodes, respectively and independently.

In a method of manufacturing a semiconductor device, an electrode layer is formed on a surface of a semiconductor substrate, and a resin insulation layer is formed on the surface of the semiconductor substrate so that the electrode layer can be covered with the resin insulation layer. A tapered hole is formed in the insulation layer by using a tool bit having a rake angle of zero or a negative value. The tapered hole has an opening defined by the insulation layer, a bottom defined by the electrode layer, and a side wall connecting the opening to the bottom.

A discharging nozzle is provided in an inside space of a metal cylinder for supplying an assist gas from an inside of the metal cylinder. The gas discharging nozzle shuts a high density energy beam intruding into the inside space of the metal cylinder through a hole, so that the energy beam is prevented from being emitted to an opposite side inner surface of the metal cylinder. Dross formed during the cut-machining is drifted and swept to the outside by an assist gas flowing out from the inside space of the metal cylinder through the hole, and is blown out by the assist gas flowing on an outside surface of the metal cylinder around the hole, thereby preventing the dross from sticking to peripheral area of the hole.

A transparent electroluminescent display panel overlaps at least a part of a conventional instrument panel, and forms a combined display panel assembly. Overlapping front and back panel displays are selectively displayed. The front electroluminescent panel displays additional information such as navigation maps, and is turned off when such additional information is not required while the back panel is turned on. The present invention eliminates undesirable reflected images of the back panel vaguely shown on the front panel when the front panel is on and the back panel is off. A light attenuator, eliminates the reflected images. It decreases the intensity of light emitted from the front panel to the back panel, and is disposed between the back and the front panels or built into the electroluminescent panel, so that the reflected images are eliminated.
