Abstract: The present invention provides for improved testing of an integrated circuit 1. In order to measure a signal S in circuit 1 a multi-pattern is placed in shift register 70. The multi-pattern is generated by overlaying at least two test patterns Ax and Bx. Therefore the signal S changes its state in response to only a small amount of shift operations.

Abstract: The plate-shaped component (1) has a sealing (2) surrounding its side faces (2a) and is easily exchangeable. The surrounding sealing (2) is an integral part of component (1) and has varying thicknesses along its length. This allows compensating for dimensional variations of the plate-shaped component (1) by suitable production processes, such as casting or spraying, and keeping the fixed external dimensions of the component (1) surrounded by sealing (2). An overhanging area (3), positioned on component (1) and surrounded by sealing material, serves as a stop and permits component (1) to be flush-mounted in a housing (7) from the inside. A wedge-shaped elevation (4) of sealing material, which acts as a pinch or fold and is positioned in the overhanging area (3), improves the flush mounting still further. For outdoor installation, the plate-shaped component (1) may be additionally provided with heating as well as temperature measuring means (5, 8). For this purpose, the component may comprise connecting electrodes for power supply as well as heating wires extending therebetween, or an areal oxide layer suitable for the same purpose, which, if required, may be a transparent and thus invisible layer.

Abstract: PAPER TRANSPORT MECHANISM FOR A PRINTER UNIT A transport mechanism for single and endless forms includes a print roll as a support and transport means, and also includes a pin transport means designed as a plug-in unit. The print roll can be driven via a shaft, couplings and gears by means of a stepper motor as well as a handwheel. A ratchet wheel carries one coupling part and, by means of the handwheel, can be shifted, latched, and coupled to the other coupling parts on the free-running gear arrangement. In the coupled state, the tractors and the roll are driven via the free-running gear arrangement located on the shaft of the print roll. In an intermediate position, without coupling, only the roll is driven by hand or motor, if there are no tractors. In a further position the ratchet wheel and the print roll are latched, so that only the tractors are driven.

Abstract: The steel type band moves in front of the rectangular, block-shaped printing platen over which passes the paper web to be printed. The band has a track of individual type symbols below which are located the timing tracks. The impact surfaces on the platen has on its front and rear sides, layes made of bearing material esp. lead bronze against which the printing hammers impact the printing type on the type band. The use of such a platen markedly increases the service lift of the type band and improves print quality by offering uniform frictional characteristics.
