Patent EP-0325181-A2 (EP)
Inventor: BRASSINGTON MICHAEL P
IPC: H01L29/732
Filed: 1989-01-14
Abstract: A method of making bipolar and MOS devices simultaneously using a single fabrication process. In one embodiment of the invention, a silicon substrate is divided into bipolar and MOS regions. A thin layer of gate oxide, having a thickness in the range of from approximately 150 angstroms to 300 angstroms, is thermally grown on the silicon substrate. A thin layer of polycrys­talline silicon, having a thickness in the range of from approximately 500 angstroms to 1000 angstroms is deposited on the gate oxide layer to protect the gate oxide layer during subsequent processing. Both the thin polysilicon layer and the gate oxide layer are removed from the bipolar region where the emitter is to be formed. To maintain the integrity of the gate oxide layer during etching, a photoresist mask used during the polysilicon etch is retained during the gate oxide etch, and the gate oxide is etched in a buffered oxide solution. A thick layer of polysilicon then is depos­ited on the bipolar and MOS regions of the silicon sub­strate, and the substrate is masked and etched for form­ing the emitter and gates of the bipolar and MOS devices, respectively.

IPC: G06F15/16

Abstract: Propositional reasoning is performed on a massively-parallel processor, with sets of element value combinations being handled by separate processing units. A host processor operates as a problem-solver, generating requests for propositional reasoning, and also operates as an interface between the problem-solver and the parallel processor. In response to a request that includes a formula, the interface provides one or more formulae such as justifications and class restrictions. The interface provides instructions to the parallel processor based on each of these formulae. The instructions based on each formula are provided so that the set of element value combinations handled by each processing unit is not divided or forked into two subsets until necessary. If possible, forking is avoided by forcing the value of an element to the only value consistent with the current formula. Furthermore, if no additional processing unit is available for forking, the current formula is kept on a queue of formulas, and the corresponding instructions are subsequently repeated. In this manner, the host processor orders the formulas into a sequence that reduces the number of processing units required. When necessary, a selected assumption is forced to one value to free processing units; its other value is considered subsequently by backtracking. Each element value is assigned one or more bit positions in each processing unit, but when the values in all the processing units are the same for a given element, its bit position may be reclaimed, to reduce memory requirements. The interface also responds to a request for results by sending instructions that use circuitry in the parallel processor to obtain a combined result from the processing units.

Abstract: A computer system having a display adapter, a refresh buffer and an interactive display terminal with a screen display on which is formed a plurality of at least partially overlapping windows, a depth buffer is added to the display adapter for providing clipping assistance to the software-based window manager in the CPU. The window manager is programmed to monitor the current depth position of each of the plurality of windows. In response to an input request for a rearrangement of the windows, the window manager assigns a new depth value to the subject matter associated with each affected window and requests that each application retransmit at least the affected subject matter. The depth buffer includes an array which stores the depth values of the subject matter associated with each of the windows being currently displayed on the screen. In response to the rearrangement request, depth buffer receives the new depth values for the subject matter associated with each affected window from the window manager and compares the current depth values. If the comparator determines that the new subject matter has a depth value associated with the same window or a window closer to the viewer, the depth buffer notifies the refresh buffer to store the newly transmitted subject matter from each of the applications being run on the CPU. In an alternative embodiment, two buffers are used to store the depth information associated with the subject matter in a window, i.e. a W-buffer to store the depth of each window relative to a reference point and a Z-buffer to store the depth of the subject matter within a window.

Abstract: A bogie for rolling stock, in particular for high speed vehicles, but suitable for use on railway lines not designed for high speed. The bogie comprises a swing bolster (21) carrying the vehicle body, a guide frame (1) carrying a pair of wheel sets (6), means for connecting the guide frame (1), the swing bolster (21) and the wheel sets (6), as well as a braking equipment (10). Each wheel set (6) comprises a pair of wheels (8) keyed to an axle (7) carried by support means for rotation, in particular axle boxes (11) with integral brackets (13). The swing bolster (21), which supports the weight of the vehicle body, rests directly on the wheel sets (6) through elastic supports and the guide frame (1) is not rigid, but articulated, the longitudinal members (2) of the frame (1) being interconnected by articulated cross members (3), the respective joints (4) of which lie equidistant from the centre and in diagonal alignment. The bogie is suitable to be used in operation both on railway lines designed for high and on lines not designed to this purpose. In particular, the performances of the bogie with guide frame unloaded of the vehicle body weight and articulated are considerably better with respect to the dynamic stability, curve inscribability and safety from derailment when passing on skew length track. The constructive solutions adopted make easier the car replacing operation.
