Abstract: ABSTRACT OF THE DISCLOSURE          There is herein disclosed an inverter of an integrated logic structure which is formed in a semiconductor device.  More particularly, an epitaxial layer is formed on a semiconductor substrate.  This layer includes a laterally arranged transistor and a vertically arranged transistor in side by side relationship.  The collector of the lateral transistor is connected integrally with the base of the vertical transistor.  The base of the lateral transistor is connected integrally with the emitter of the vertical transistor.          Supply voltage terminals are provided, one of which is connected to the emitter of the lateral transistor and the other of which is connected to the base of the lateral transistor as well as to the emitter of the vertical transistor.  Diodes corresponding in number to the number of collectors in the vertical transistor are connected respectively in parallel with each base-collector junction of the vertical transistor and poled the same as the base-collector junctions.  The emitter of the vertical transistor is formed as a buried layer in the semiconductor device.  The lead from the outer surface to this buried layer is a highly doped zone, preferably formed by ion implantation. Each inverter is separated from an adjacent inverter in the same semiconductor chip by suitable isolation means, such, for example, by an insulating guard ring of SiO2 or by pn junction isolation.  The output is taken from the collectors of the vertical transistor.

Abstract: ABSTRACT OF THE DISCLOSURE        A device for connecting either one of two alternative incoming Bowden cables with an outgoing Bowden cable has a frame with a cam plate. Two mirror-image cam curves each has a valley surrounded by higher cam portions. The incoming cables are connected to opposite ends of a link arm, the ends of which are also provided with cam-engaging rollers. The center of the link arm is via an intermediate link connected to a swing arm, the free end of which is connected to the outgoing cable. In neutral position, the link arm extends between the cam valleys.          When one of the incoming cables is operated, the associated cam engaging roller will climb out of its valley, thereby pushing the link arm towards the opposite cam curve so that the opposite cam engaging means engages its cam valley to form a pivot axis for the link arm. The intermediate arm transfers the pivoting movement to the swing arm and outgoing cable.
