摘要:
A photoelectron beam converting device including a semiconductor substrate having a p-n junction formed between an n-type region and a p-type region and an opening portion formed on the side of the semiconductor substrate. An electron beam is generated by a light which enters from the opening portion and by a reverse voltage to be applied to the p-n junction.

An electron-beam information exchange apparatus adapted to effect information exchange in incoming light signals and outgoing light signals by utilizing electron beams. The apparatus has a plurality of electron beam generating means for generating electron beams according to the incoming light signals; a plurality of electron beam deflecting means for independently deflecting individual electron beams emitted from the electron beam generating means; and a plurality of electron beam detecting means for reproducing information from the thus-deflected electron beams to generate the outgoing light beams. The electron beam detecting means controls the electron beams so that each of the electron beams is made incident upon a desired one of said electron beam detecting means. Also, the electron beam generating means are semiconductor devices for generating electron beams.
摘要:
A recorder having an ink re-supply system for a moving ink tank has a movable record element for recording data, a first tank movable with the record element, a fixed second tank, a recording liquid path connecting the two tanks, and a supply device for supplying recording liquid during periods when the recording liquid path is established. Structure is also provided for connecting and disconnecting the recording liquid path. The connection/disconnection structure includes an opening through which part of the recording liquid path extends. The recorder can also include a flexible curtain blade for protecting the inside of the recording liquid path and through which the recording liquid path extends when it is established by the connection/disconnection means structure.
