    • A holder 20 is rotatably connected to a body 10. A scribe tool 30 is attached to one end of the holder 20. A plate spring 16 is fixed to the body 10, and a receiving plate 26 is fixed to the holder 20. A piezo-actuator 40 is interposed between the plate spring 16 and the receiving plate 26. One end of a plate spring 50 having a small spring constant is fixed to the holder 20. The body 10 is provided with an adjustment screw 60. When a lower end part 65 of the adjustment screw 60 is protruded, the lower end part 65 presses the plate spring 50 for flexure, thereby generating a resilient force to the plate spring 50. By this, a rotational force is given to the holder 20 and thus a pressing load directing toward a workpiece is given to the scribe tool 30.

    • An unencapsulated solid electrolytic capacitor includes a substantially flat, multi-layer solid state capacitor element having an anode lead-out wire welded to a solderable flat anode terminal plate located in the same plane as that of the principal surface of the capacitor element. The terminal plate includes a pair of protrusions formed on a side of the terminal plate remote from the capacitor element. The lead-out wire has an end portion positioned between, but not extending beyond, the protrusions. A method of manufacturing the capacitor includes forming a capacitor element array by aligning respective capacitor element lead-out wires so that they are substantially parallel and are spaced at a predetermined pitch, forming notches at substantially the same locations in the lead-out wires. An anode terminal frame is constructed from a metal strip by forming a plurality of protruding regions extending from one side of the strip at the same pitch as that of the capacitor element array, and by forming in each of the protruding regions an opening defined by an end portion spaced apart from the strip and a pair of narrow branch portions extending between the end portion and the strip. The capacitor element array is then superposed on the anode terminal frame so that the notches are in registration above the openings, and the lead-out wires are welded to the respective end portions. The lead-out wires are then severed at the notches, and the narrow branch portions are cut along a line located between the severed ends of the lead-out wires and the metal strip.
