Abstract: A pixel circuit includes a light-emitting element that has a luminance corresponding to a level of a driving signal; and a signal generating circuit that generates a driving signal indicating the luminance of the light-emitting element on the basis of a data signal. The signal generating circuit includes a driving transistor that generates a driving signal by supplying a voltage corresponding to a data signal to its gate electrode, and a time constant circuit that rounds a waveform of the driving signal supplied from the driving transistor to the light-emitting element.

Abstract: An annular magnetic encoder in which a plurality of S poles and N poles, the S poles and the N poles being magnetic poles, are alternately arranged, the magnetic encoder has a structure in which a change in width of the magnetic poles in a rotational direction according to a rotational angle allows the rotational angle to be specified, so that little rotation can specify a rotational angle.

Abstract: A fuel injection system (10) for a multiple-cylinder engine includes a single solenoid-operated fuel metering valve (12) connected through fuel lines (50) to a plurality of fuel injection nozzles (52). The fuel metering valve (12) has a solenoid-operated movable valve member (14) that opens and closes a single discharge opening (26) having a first metering orifice (58). Each injection nozzle (52) has an equally calibrated second metering orifice (90) that serves to distribute the fuel metered by the first orifice evenly over all of the fuel injection nozzles. Preferred forms of the fuel injection nozzle is also disclosed.
