摘要： An electrical discharge machining apparatus for forming minute holes in a workpiece has a machining electrode supported in V-shaped grooves for forming a minute hole through an electrical discharge between the machining electrode and the workpiece. The machining electrode is movable toward and away from the workpiece. The workpiece is movable between a position below the machining electrode and a position below a microscope disposed in conjugate relation to the machining electrode. After a position to be machined has been set by the positioning means, the workpiece is moved to the position below the machining electrode for electrical discharge machining. The machining electrode is subjected to little displacement while it is being rotated, and the position to be machined can be determined with high accuracy. The electrical discharge machining apparatus can quickly form a neat minute hole of small out-of-roundness and reduced surface roughness in the workpiece at a correct position thereon.

摘要： The present invention discloses a film capacitor and a method for making the same. A capacitor element formed by rolling or laminating metalized films less than 3.5 microns in thickness has ends coated with ion plating to form block terminals so that the strong bonds between the ends of the capacitor element and the terminals may be obtained with the resultant decrease in contact resistance therebetween. In order to increase the mechanical strength of the terminals a conducting layer may be formed on the terminals by metal spraying, and in order to increase the bond the ends of the capacitor element may be subjected to etching prior to ion plating so that the roughed end faces offer teeth to which the metal terminals cling. Thus the present invention provides a film capacitor which is considerably compact in size, light in weight yet highly reliable and dependable in operation and inexpensive to manufacture.
