The invention provides: a gas sensor device that is capable of removing a component adsorbed on a gas sensor by relatively simple means and easily restoring a signal baseline of the gas sensor to a constant state; and a method for removing a gas component. The gas sensor device according to an embodiment of the invention includes a gas sensor and cleaning means that contains a liquid for cleaning the gas sensor. The gas sensor includes a sensor main body that is capable of detecting a characteristic parameter of a component present in a gas phase or a liquid phase, and a sensitive membrane that is coated on a surface of the sensor main body and is durable against the liquid.

A multi-layer photoelectric conversion device and technology is disclosed. A first photoelectric converter is separated from a second photoelectric converter by an insulative layer. The photoelectric converters may be of a variety of types, and the insulative layer provides protection to reduce pinhole faults in the multi-layer photoelectric conversion device.

Combined photoelectric conversion device

A light emitting element array is provided with a plurality of light emitting diodes arranged in a row, field-effect transistors connected in series with the respective light emitting diodes, shift registers for individually turning the respective field-effect transistors on by individually supplying drive signals to gates of the respective field-effect transistors, and an emission controller for driving the light emitting diodes by supplying the emission signals, whose levels are so differed as to correspond to the respective light emitting diodes, to the light emitting diodes connected with the field-effect transistors when these field-effect transistors are individually turned on.
