    Abstract: There is provided a traffic sign apparatus that can improve the luminance of a sign surface which emits light by ultraviolet irradiation, and the uniformity ratio of illuminance, so as to enhance the visibility thereof in the nighttime. The traffic sign apparatus 10 includes a sign body 11 having the sign surface 14 which emits light by ultraviolet irradiation, and an irradiation device 12 for irradiating ultraviolet rays onto the sign surface 14.

    Abstract: There are provided a transmission circuit capable of stabilizing high-speed data transfer by driving current, a data transfer control device, and electronic equipment. An HS current driver (transmission circuit) included in a data transfer control device has a current source connected between a first power supply AVDD and a node ND, and switching devices SW1 to SW3, one ends of which are connected to the node ND. The other end of the switching device SW1 is connected to a DP terminal. The other end of the switching device SW2 is connected to a DM terminal. The other end of the switching device SW3 is connected to a DA terminal. The DA terminal is connected to a second power supply AVSS inside or outside the transmission circuit. The transmission circuit is configured so that impedances of each current path from the node ND through the switching devices SW1 to SW3 become substantially equal when the switching device is turned on. This prevents an increase in the voltage of the node ND in a non-signal-transmission period.

    Abstract: There are provided a method and an apparatus for removing electrostatic charges from high resistivity liquid. An insulating film is formed on the surface of a conductive element which is in contact with the high resistivity liquid wherein the insulating film has such a thickness that a tunneling current may flow through the insulating film, thereby preventing the highly purified high resistivity liquid from being contaminated, as well as from becoming acid. Thus, objects to be treated with the high resistivity liquid become free of electrostatic charges without any contamination.
