专利汇可以提供Facsimile system utilizing single crt for scanning and image reproduction专利检索,专利查询,专利分析的服务。并且An electrostatic facsimile system utilized a single cathode ray tube in performing both scanning and image reproduction operations. In one embodiment, one gun of a twin gun tube is used to produce a flying spot for scanning a document to be reproduced. The light reflected by the document is collected by a photomultiplier tube which produces an electrical image signal which is fed, through suitable monitoring means, to the second gun of the cathode ray tube. The external ends of the wire array terminate on the surface of a suitable receiving medium, where an electrostatic image is produced. Such image is then developed and fixed to produce a facsimile of the original. In a second embodiment one electron gun of a cathode ray tube is used for both scanning and image reproduction operations by providing means for switching the beam produced by the signal gun so that it alternately produces a flying spot on the document and produces an electrostatic image on the wire array.,下面是Facsimile system utilizing single crt for scanning and image reproduction专利的具体信息内容。
