When error correction data, which is to be inserted into transmission data at specific intervals, is generated by calculating exclusive-OR of the transmission data, cumulative exclusive-OR of the transmission data is continuously calculated independent of the error correction data insertion intervals. Exclusive-OR between a calculation of the exclusive-OR at the time of the previous error correction data insertion and a calculation of the exclusive-OR at the time of the current error correction data insertion is calculated, thereby generating error correction data to be inserted at the present time. This provides efficient error correction data calculation.

The present invention provides an electro-optical panel that is capable of effectively exhibiting the features of the construction in which two transistor elements are used per pixel, and an electronic device using the electro-optical panel. A pixel includes a P-channel thin-film transitor (TFT) in which the gate electrode is connected to a scanning line, and an N-channel TFT in which the gate electrode is connected to a scanning line. When the P-channel TFT and the N-channel TFT are turned on, the voltage of an image signal supplied to a data line is written into a holding capacitor HC and a holding capacitor LC. The holding capacitor HC is connected to the drain electrode of the N-channel TFT. Also, the holding capacitor HC is connected to the drain electrode of the P-channel TFT via a wiring line L. Since the wiring line L is formed of a low-resistance material, the time constant when the image signal is written into the holding capacitor HC via the P-channel TFT can be decreased.

Provided is a Schottky emitter having the conical end with a radius of curvature of 2.0 μm on the emission side of an electron beam. Since a radius of curvature is 1 μm or more, a focal length of an electron gun can be longer than in a conventional practice wherein a radius of curvature is in the range of from 0.5 μm to not more than 0.6 μm. The focal length was found to be roughly proportional to the radius of the curvature. Since the angular current intensity (the beam current per unit solid angle) is proportional to square of the electron gun focal length, the former can be improved by an order of magnitude within a practicable increase in the emitter radius. A higher angular current intensity means a larger beam current available from the electron gun and the invention enables the Schottky emitters to be used in applications which require relatively high beam current of microampere regime such as microfocus X-ray tube, electron probe micro-analyzer, and electron beam lithography system.

An object of the present invention is to enable a real-time distribution even if the band of a network varies. A distributing apparatus receives a packet retransmission request or a packet restoration notification, which is transmitted from a receiving apparatus, with an error information receiving unit. If the number of received retransmission requests or that of restoration notifications becomes equal to or larger than a certain value, a distribution band controlling unit decreases a band used to distribute a packet by a certain band.
