Abstract: A metallized-film capacitor includes a slit (5a) at approx. center of the width (W) of an effective electrode which actually forms a capacitance of a pair of deposited electrodes (110, 210). Divisional electrodes (2a, 2b) exist at a place between the center and insulation margins (4a, 4b), and the electrodes (2a, 2b) are coupled in parallel to each other by fuses (7a, 7b) disposed away from metallized contacts (6a, 6b). Such a structure as placing fuses (7a, 7b) away from the contacts (6a, 6b) allows reducing a current supplied from the contacts (6a, 6b) and running through fuses (7a, 7b), thereby lowering heat generated from fuses (7a, 7b). As a result, a temperature rise in the metallized-film capacitor can be suppressed.

Abstract: A variable position sensor has a stationary portion and a moveable portion. A plurality of plates are positioned on one of the members with the surfaces of the plates forming segments of a larger surface. A single plate is mounted on the other of the two members. One pole of an electric potential is applied to a first of the plurality of plates on the one member and the second pole of the electric potential is applied to the single plate on the other member. Similarly a pole of an electric potential is separately applied to each of the other of the parallel plates and to the one plate. When the one plate is positioned adjacent one of the plurality of plates a capacitance is formed between the adjacent plates, and by detecting the capacitance the position of the one plate can be determined.
