    Abstract: A display system using a gaseous glow indicator tube having a plurality of indicator electrode units such as seven, for instance, each unit including a plurality of cathodes and having anodes disposed opposite the indicator electrodes. The indicator electrode units and the anodes are contained in an envelope and a driving circuit is provided for selectively feeding current to the indicator electrode units in such a manner that adjacent ones are not caused to glow successively.

    Abstract: A solid state imaging device with a plurality of line sensors (3, 4, 5, 6) in which each line sensor receives the light through the divided light paths from a straight line of a document into each unit is disclosed. The divided light paths are obtained by bending each rod lens (8) of a rod lens array (2), providing concave or convex lenses or convex mirrors or by providing transparent plates at different angles. As a result of the dividing of light path, the line sensors pick up linear image data without abutting each sensor in a straight line.

    Abstract: In an automatic focus control system for video cameras part of the object light is diverted through an optical sub-system (22) to a detecting unit (30) the output signals of which are used for controlling focusing of the optical main system. The output signals from the detecting unit are used for variably controlling a diaphragm (21) in the sub-system. The state of focus of the main optical system (2, 3, 4, 5 and 8) is sensed and depending on whether the main optical system is in considerably defocused state or approximately focused state, the effective diameter of the diaphragm (21) in the optical sub-system is reduced or enlarged, respectively.

    Abstract: A data input device for an electronic computer or calculator has an electro-mechanical transducer, preferably comprised of an electret and an electrode confronting each other with a gap therebetween which is narrowed by manual operation of a key, to electrostatically induce an electric charge by which a field effect transistor is controlled for producing an output, and a switch, preferably constituted by a second field effect transistor, for shunting the first mentioned field effect transistor and thereby removing the controlling electric charge from the latter so that only a single output is obtained from the first field effect transistor for each manual operation of the electro-mechanical transducer. A diode is further preferably connected between the electrode and ground potential and has its polarity arranged to remove the induced charge which remains on such electrode after the shunting operation of the second field effect transistor and the return of the electret and electrode to their normal spacing.
