Patent ES-8306278-A1 (ES)
Title: Display device.
IPC: G09G3/20
Filed: 1982-07-14
Abstract: In order to provide a passive electro-optical display medium in a matrix display device with a sufficiently steep threshold with respect to the applied voltage and having a memory, a switching element (9) is placed in series having each picture element. The switching element (9) is provided between a picture electrode (6) of each picture element and a driving electrode (8). The switching element (9) is formed by a polysilicon island (20) in which n+-doped regions (22,23) are provided which are separated by a p-doped region (21). As a result of this, two series-arranged, oppositely directed p-n junctions are formed of which one is always reverse biased. The width of the p-doped regions is so small that punch-through occurs between the two p-n junctions before one of the p-n junctions breaks down. Due to the occurrence of punch-through, the series resistance of the switching element is negligibly small so that a favorable RON/ROFF ratio is obtained and the picture elements can be driven with comparatively low voltages.

Patent ES-8403216-A1 (ES)
Title: A process and the latter's corresponding apparatus for analysing and classifying particles in suspension in a liquid
IPC: G01N35/00
Filed: 1983-02-18
Abstract: A description is given of a particle separator for classifying particles in suspension in a liquid in accordance with certain characteristics, using a method and an apparatus for detecting a change in the point of fractionation into droplets of a stream of liquid in the form of a jet subjected to vibrations. The vibrations produce amplitude undulations on the surface of the jet- form stream. The amplitude of the undulations is monitored or checked at a fixed point of the jet-form stream before the point of fractionation into droplets. A change in the amplitude of the undulations at this fixed point produces a signal voltage whose value is proportional to the change in amplitude. This signal voltage may be used (1) for alerting the operator to the fact that a change has occurred at the point where the jet-form stream divides up into droplets, (2) for automatically controlling the intensity of the vibrations in order to re-establish the undulation amplitude at this fixed point to its original state, or (3) in order automatically to deactivate the classification part of the apparatus. It is possible to use any of these procedures or any combination thereof.
