Patent DE-4018025-A1 (DE)
Inventor: MATHEA HANS
IPC: G03G15/20
Filed: 1990-06-05
Abstract: Conventional laser printers for continuous webs/labels have either gentle fixation, are relatively expensive, bulky and difficult to operate and service or are small, compact and robust but damage the printed material by heat and pressure. The profitability of a few larger versions is increased by making repeated use of the strips to be labelled. However, a separating device must be used afterward. The invention indicates a laser printer for continuous webs/labels which is inexpensive, economical to use, does not damage the adhesive layer or printed material and is easy to operate and service. The laser printer has a separating device in the same housing and is extremely compact.

Patent DE-4211162-A1 (DE)
Inventor: BUDINI MICHAEL DIPL PHYS
IPC: G06F17/50
Filed: 1992-03-31
Abstract: The invention relates to a hardware electronic ASIC prototyper which enables integrated circuits or ASICs to be emulated so that it is possible to test the chip to be created in the later hardware environment. Emulation systems are known which consist of a matrix of configurable logic blocks, configurable I/O cells and a configurable wiring. These systems only emulate the functional behaviour of the desired circuit.   According to the invention, adding programmable delay units into the logic cells and using programmable switching networks with delay units for interconnecting the logic modules formed from a plurality of logic cells has the result that the time characteristic of an ASIC is taken into consideration in the emulation so that complete emulation is achieved. By deliberately setting all inputs to a defined logic state, an error emulation can be achieved. The detection of "race" problems is possible by means of the programmable delay units. <IMAGE>
