    摘要: A disposable film package of the type having a taking lens comprises a film casing; a film cartridge containing a high speed film therein in said film casing; a viewfinder; and a scene brightness indicating member disposed in the viewfinder. The indicating member becomes visible or invisible according to scene brightness conditions. When the indicating member becomes visible, the photographer is thus given warning that an improper exposure would result.

    摘要: A liquid crystal display device using an alignment film of ladder-type organosilicone polymer or cross-linking product of cross-linkable ladder-type organosilicone polymer makes a homogeneous liquid crystal orientation, irrespectively of the kind of the liquid crystal used, never lowers its orientation ability even when fusion-sealing or sealing of the liquid crystal device is made with glass or thermosetting resin, and makes a clear display owing to the alignment film being colorless. The alignment film is insoluble in the liquid crystal used.

    摘要: A current interruption type ignition system for an internal combustion engine comprises an ignition coil including a primary coil portion and a secondary coil portion; an exciter inducing an AC voltage in synchronism with rotation of the engine to be supplied to the primary coil portion of the ignition coil; a first semiconductor switch provided in parallel to the primary coil portion to conduct a current from the exciter therethrough; a second semiconductor switch provided on a controlled terminal of the first semiconductor switch so that the second semiconductor switch, upon conduction, causes the first semiconductor switch to be turned off so as to abruptly conduct a primary current into the primary coil portion of the ignition coil; and a signal source generating an ignition signal at the ignition position of the engine. The second semiconductor switch is provided in series to the primary coil portion of the ignition coil while the first semiconductor switch has the controlled terminal connected through the primary coil portion of the ignition coil to the exciter, whereby the first semiconductor switch is turned on by a signal applied by the exciter through the primary coil portion of the ignition coil.
