Title: System for electronic transmission of still pictures or graphic reproductions
IPC: H04N1/17
Filed: 1971-07-29
Abstract: 1365918 Facsimile data transmission PIONEER ELECTRONIC CORP 29 July 1971 [29 July 1970] 35767/71 Heading H4F A system of facsimile data generation and transmission employs a rapid preliminary scan of each sub area of the image in turn, and only when useful information in a sub-area is detected is a regular scan of that sub-area initiated before the switching of the rapid scan to the next subarea. As shown pulse generator 1 produces vertical scan pulses for a sub-area, and generator 13 derives deflection signals for scanning tube 18, while for each vertical pulse a pulse multiplier 2 produces n horizontal scan pulse which similarly controls horizontal scan of the sub-area. Reflected light from the image is detected at 20 and this signal passed via 22 to a discriminator circuit 3. According to whether or not discriminator 3 recognizes useful information in the subarea, the next pulse from 1 is directed at 4 either to 5 or 7. Pulse generators 5 and 6 operate similarly to 1 and 2 but at a slower pulse rate to produce by means of 15, 14 the regular scan signals for the sub-area, and 5 opens gate 23 to pass the video signals to the output. Should no useful information have been recognized in the preliminary scan, or at the end of the regular scan of the sub-area, 7 receives a pulse and steps the count in 8 to increase the horizontal deflection signal supplied by 10 and thus step to the next sub-area in the line. This action is repeated (initiated by a pulse from 7 via 11 to 1) until the last sub-area of a line has been dealt with, when vertical shift to the next line is initiated by 9 which advances the document at 19 by means not shown. Figure 4 (not shown) illustrates a receiver for the facsimile data in which the sync. signals (from 6 and 9, Fig. 1) are separated from the video signals and used to control the generation of sub-area scan signals and shift signals for stepping from one sub-area to the next, these deflecting a CRT spot modulated by the picture information to control exposure of a photographic film.

The layers may be formed directly on the respective substrate or on a coating applied thereto of a metal such as gold, for example, and may be deposited by electroplating (examples of electrolytes are given) or by dry-coating such as sputtering, ion plating or vacuum evaporation. It may be advisable to heat the first layer to a temperature close to its melting point while dry-coating the second layer in order to increase the amount of alloy formed at the interface.
