Abstract: In processing a sequence program for a b-contact, an input signal is logically inverted ultimately, and the processing for the b-contact requires logical inversion processing which is not involved in processing an a-contact. A logical inversion circuit (8) is provided for logically inverting an input signal corresponding to b-contact designation of the sequence program before the input signal is fed to a central processing unit (3), so that inversion processing in the central processing unit can be dispensed with and operation speed can be increased. The application of a logical inversion signal to the logical inversion circuit can readily be effected by utilizing an address line of the central processing unit.

Abstract: c This invention relates to infrared transparency films and films for thermal imaging processes, and in particular, to a coating material for such films. 
     Infrared imaging involves the use of a focused infrared lamp to heat an infrared absorbing image, i.e., the «original», which is in contact with a substrate, e.g. a transparencyfilm, having thermally sensitive imaging chemicals. Upon absorbing the focused infrared light, the infrared absorbing image heats the thermally sensitive imaging chemicals on the substrate, causing a chemical reaction, resulting in a copy of the original image on the substrate. 
     When projection transparencies are prepared from originals which are plain paper copies prepared from electrophotographic imaging processes, localized heating of the original results in partial remelting of the toner powder thereon, causing the original to adhere to the transparency. When the original is separed from the transparency, toner powder from the original is transferred to the transparency film, resulting in partial destruction of the original and irregular black spots on the transparency. 
     This invention provides a coating for infrared transparency films and thermal imaging films comprising a copolymer formed from (a) at least one fluorocarbon monomer and (b) at least one monomer which imparts hardness to the copolymer. The coating serves to prevent the transfer of toner powder from an original to the transparency film.

Abstract: in a process for forming vias in integrated circuits, a layer of a first metal is formed on a semiconductor substrate. A layer of a second metal is formed on the first metal layer. The second metal layer is etched in a predetermined via pattern with a second etchant which reacts with the second metal and which is substantially unreactive with the first metal. The first metal layer is then etched with a first etchant which reacts with the first metal and which is substantially unreactive with the second metal or with the semiconductor substrate in order to form a predetermined interconnect pattern having a predetermined contacting relationship with the predetermined via pattern. This process may be used to generate second and subsequent levels of vias and interconnects which can be used to contact metal layers at any level directly to the substrate by building via posts from the substrate to any desired metal layer.
