摘要:
A semiconductor device includes a PLL (Phase Locked Loop) circuit configured to generate a reception clock signal and a transmission clock signal based on a reference clock signal which has been subjected to frequency-modulation; a serializer configured to convert parallel data into serial data in response to the transmission clock signal to output the serial data; and a CDR (Clock Data Recovery) circuit configured to perform clock data recovery on reception data in response to the reception clock signal to output recovery data. A deserializer is configured to convert the recovery data into parallel data; and a loop-back line configured to supply the serial data outputted from the serializer to the CDR circuit as the reception data.

An electrochromic display is disclosed which comprises an array-side substrate (10) wherein a TFT (14) and a pixel electrode (15) connected with the TFT (14) are formed, a color filter-side substrate (50) wherein a counter electrode (53) is formed, and an electrolyte layer (80) injected between the array-side substrate (10) and the color filter-side substrate (50). In this electrochromic display, the TFT (14) is formed to have an area not less than 30% of the area of the pixel, thereby supplying a larger current. Consequently, oxidation-reduction reaction in the electrochromic phenomenon proceeds at a higher rate, thereby enabling a high-speed response.

An electro-optical device includes pixel regions arranged at intersections of a plurality of data lines and a plurality of scanning lines on an element substrate. A sensor element, a sensor signal line for outputting a signal from the sensor element, a common wiring line, and a capacitive-coupling-operation bidirectional diode element are disposed at an end of a region on the element substrate in which the pixel regions are arranged. The capacitive-coupling-operation bidirectional diode element includes two capacitive-coupling-operation diode elements each including a semiconductor element including a source electrode, a drain electrode, a semiconductor layer having a channel region, and a gate electrode facing the channel region with a gate insulating film disposed therebetween, and a capacitor element arranged between one of the source electrode and the drain electrode and the gate electrode, the two capacitive-coupling-operation diode elements being electrically connected in opposite directions to each other. The sensor signal line is electrically connected to the common wiring line via the capacitive-coupling-operation bidirectional diode element. A control wiring line for supplying a gate voltage setting the semiconductor elements of the capacitive-coupling-operation bidirectional diode element to be in a non-conducting state is disposed for the capacitive-coupling-operation bidirectional diode element.

The detergent composition for petroleum refining apparatus in accordance with the present invention is one used as being mixed with a petroleum solvent when the inside of a petroleum refining apparatus is washed with the petroleum solvent in a nonaqueous system, wherein the detergent composition contains a surfactant having a solubility of at least 10 with respect to a diesel fuel at a temperature of 25° C. When this detergent composition for petroleum refining apparatus is used together with the petroleum solvent, soil components are rapidly impregnated with the petroleum solvent. Consequently, sufficient washing effects can be exhibited. As a result, the washing efficiency can be improved remarkably, whereby the washing time within the petroleum refining apparatus can be shortened greatly.
