Abstract: ABSTRACT:            "Electron lithography masks".           A layer of electron sensitive resist (13) on a semiconductor substrate (12) is exposed to a patterned electron beam emitted from an erasable photocathode mask (6,9) in an electron image projector (5). The mask is formed from a transparent, e.g., quartz, plate (6) on which is provided a layer (9) of caesium iodide or other photoemissive material. A photoemissive pattern is defined in layer (9) by selective direct exposure to a beam of photons, electrons or ions preferably in an evacuated carbon-containing environment whereby the photoemission of the exposed areas of the caesium iodide is lowered. Alternatively using a beam of charged particles with a relatively high current density the exposed parts of the caesium iodide are actually removed by evaporation. In both cases, the patterned caesium iodide can be removed by rinsing in water and the transparent plate (6) can be reused with -the same or different photoemissive pattern.                (Figure 1).

Abstract: ABSTRACT Preparation of granules by making solid nuclei grow in a fluidized bed, by causing a liquid material to solidify there on, and removing the granules thus obtained, the liquid material being introduced into the bed from the bottom upwards with the aid of a feeding device provided with a central channel through which the liquid material is supplied and a channel concentric therewith through which a powerful gas stream is supplied, which creates a rarefied zone in the bed above the feeding device, wherein the liquid material is made to exit from the central channel into the rarefied zone as a virtually closed, conical film, nuclei from the bed are carried through the film with the aid of the powerful gas stream and next, during transport of the so moistened nuclei through the rarefied zone, the liquid material taken up by the nuclei is allowed to solidify.  By this process only a small amount of high-energetic gas is required, while very little agglomeration and dust formation occurs.

Abstract: ABSTRACT:          "Processor system comprising a plurality of data processors which are interconnected by a communication network."           A processor system comprises one or more stations (22, 24, 26) which are interconnected by a general communication net-work (20). Each station comprises one or more processors (34, 36). Superprocesses (74, 76, 78) which comprise one or more processes (80-90) can be executed in the stations. Each superprocess is pro-vided with mail-box space (50, 52, 54) for communication with the environment, in which mail-box space the relevant superprocess and other superprocesses can write but in which only the relevant superprocess itself can read. Processes within the same superpro-cess have variable data in common, but their register stacks are private. Each mail-box is provided with a filling indicator. In the case of a read operation in an empty mail-box space, a wait signal is issued for the initiating process; write operations in a full mail box space produce an error signal. There is also pro-vided a job control system for allocating jobs among the stations by way of an application load file. (Fig. 1).
