Filed: 1970-05-11
Abstract: 1316471 Electro-photographic copiers CANON KK 11 May 1970 10 May 1969] 22684/70 Headings G2A and G2H An electro-photographic copier comprises an original holder 45 which is turned over during copying so that both sides of the original 46 are copied. As shown before copying starts face B of the original faces downwards. As a carriage 47 supporting the holder 46 is moved leftwards, a cam 74, Fig.3, raises a roller 64, Fig.5(1) and thus raises a lever 63 which rotates a wheel 59 anti-clockwise and this rotates the holder shaft 48 clockwise against a spring 51 so that the holder is turned over and side A faces downwards. Wheel 59 is then locked in position by a lever 66. As carriage 47 then moves rightwards, firstly side A is copied and secondly a cam 77, Fig.3, raises lever 66 to release the wheel 59 and allow spring 51 to rotate the holder anti-clockwise so that side B is copied. Figs. 1, 2 (not shown) depict preferred exposure systems.

Filed: 1977-05-30
Abstract: 1535493 Semi-conductor devices MOTOROLA Inc 30 May 1977 [28 June 1976] 22832/77  Heading H1K An integrated circuit manufacturing process reduces the number of critical mask alignments and introduces a large element of self-alignment by employing two successive master masks, the first of which contains two groups of openings for successive formation of two groups of device regions using a double masking layer (e.g. nitride or oxide). This first double masking layer -is then completely removed prior to the formation of a second double masking layer. Dopant is introduced, preferably by ion implantation, through a selected area of the materials of this second masking layer, and the second master mask is then used, firstly to define the location of a third group of device regions and finally to open contact windows to selected areas of the integrated circuit.
