    Abstract: A multiplexer using an FTMOST and capable of achieving both increase in transfer rate and reduction in leakage current and an integrated circuit using the multiplexer are provided. The multiplexer includes a plurality of pass transistors each formed by a four-terminal double insulated gate field effect transistor. A second gate of the field effect transistor is connected to a threshold voltage control node, and a resistor is connected between the threshold voltage control node and a threshold voltage control voltage source. Also, the multiplexer includes a plurality of transmission gates each formed by four-terminal double insulated gate N-type and P-type field effect transistors connected in parallel. One of gates of the N-type gate field effect transistor is connected to a first threshold voltage control node, and a first resistor is connected between the first threshold voltage control node and a first threshold voltage control voltage source. One of gates of the P-type gate field effect transistor is connected to a second threshold voltage control node, and a second resistor is connected between the second threshold voltage control node and a second threshold voltage control voltage source.

    Abstract: A light irradiation apparatus includes a plurality of light sources, a plurality of light transmission paths capable of selectively transmitting lights from the plurality of light sources, respectively, and an optical fiber path provided with a plurality of light incidence ends receiving respective lights from the plurality of light transmission paths, and a single light exit end. The optical fiber path has a plurality of optical fiber bundles. Incidence ends of the plurality of optical fiber bundles configures the plurality of light incidence ends, and exit ends of the plurality of optical fiber bundles configure the single light exit end by combining themselves. A lot of optical fibers constitute the plurality of optical fiber bundles. The optical fibers of the plurality of optical fiber bundles are dispersedly arranged with each other in uniform at the single light exit end.

    Inventor: Toshihiko OGURA

    Abstract: The invention provides a method of observing an organism or any other organic specimen in an aqueous solution in a scanning electron microscope. The method includes placing the organic specimen along with the aqueous solution between opposing surfaces of a pair of first and second insulating thin films facing each other, irradiating and scanning an electrically conductive thin film provided on an outward facing surface of the first insulating thin film with a pulsed electron beam an intensity of which is changed in a form of pulses, and acquiring an image according to a change in electric potential of an outward facing surface of the second insulating thin film, in which the composition of the specimen is analyzed based on the difference between the images corresponding to the pulsed electron beam applied at different ON/OFF frequencies.
