    摘要: A duplexed bus type network in which a main transmission line and a stand-by transmission line are interconnected by a repeater (30), a changeover switch (40) or a two-way amplifier, a modem at each station is duplexed and connected to the main transmission line and the stand-by transmission line, and, upon trouble in one modem (11A), only the relevant station is switched over to the modem (21A) belonging to the stand-by transmission line. When the main transmission line is broken, all the stations are simultaneously switched over to the stand-by transmission line.

    摘要: A method of making a semiconductor device which has sharp corners on an upper surface and wherein a passivation layer is formed over said surface and windows are formed in the passivation layer for the attaching and formation of electrodes in which a photoresist material is placed over the passivation layer and selectively removed so as to leave areas of photoresist at locations over said passivation layer wherein electrodes are to be formed after which a layer of metal is formed over the surface and the metal and photoresist is removed at those portions where the photoresist layer remained after which passivation the area is etched through the windows in the metal layer and the metal layer is then removed and the electrodes are formed in the windows.
