Abstract: A slide projector (1) is suitable for the projection of mounted slides (2) accommodated in different magazines (3, 11). The magazines (3, 11) to be used are distinguished by a differing slide compartment width. The intention is to achieve a matching of the effective width of the slide change slider (4) of the projector (1) to the differing slide compartment widths of the different magazines (3, 11). For this purpose, the width of the slide change slider (4) in its active region is smaller than the spacing between one and the next but one slide (2) in the magazine (11) with the smallest slide compartment width. Moreover, a rider (14) displaceable in the direction of transport of the slide change slider (4) is displaceable along this active region as far as its face edge (4b), the width of which is greater than that of the change slider (4) and smaller than the spacing between one and the next but one slide (2) in the magazine (3) with the largest slide compartment width.

Abstract: A method for the construction of oxide-isolated silicon integrated circuit structures is described wherein two pattern-forming means are utilized, the first (40) to provide definition for the etching of silicon tubs (43) and the second (46) to coat the sidewalls (44) of the silicon tubs (43) to control oxidation thereon. When oxidation of the material in the bottom (47) of the tubs (43) is carried out to provide a deep oxide region (50), formation of a ridge or berm at the periphery of the oxide region through excess oxidation of the sidewalls is avoided. The protective coating (48) on the sidewalls (44) is obtained by conformally coating the entire wafer with material having controlled oxidation properties. This coating is subsequently removed at all locations except the sidewalls (44) by anisotropic etching prior to oxidation of the silicon (47).
