Patent EP-0447578-A1 (EP)
Inventor: CUTTS RICHARD W JR
IPC: G06F11/00
Filed: 1990-03-19
Abstract: A computer system in a fault-tolerant configuration employs three identical CPUs executing the same instruction stream, with two identical, self-checking memory modules storing duplicates of the same data. Memory references by the three CPUs are made by three separate busses connected to three separate ports of each of the two memory modules. The three CPUs are loosely synchronized, as by detecting events such as memory references and stalling any CPU ahead of others until all execute the function simultaneously; interrupts can be synchronized by ensuring that all three CPUs implement the interrupt at the same point in their instruction stream. Memory references via the separate CPU-to-memory busses are voted at the three separate ports of each of the memory modules. I/O functions are implemented using two identical I/O busses, each of which is separately coupled to only one of the memory modules. A number of I/O processors are coupled to both I/O busses. Each CPU has its own fast cache and also a local memory not accessible by the other CPUs. A hierarchical virtual memory management arrangement for this system employs demand paging to keep the most-used data in the local memory, page-swapping with the global memory. Page swapping with disk memory is through the global memory; the global memory is used as a disk buffer and also to hold pages likely to be needed for loading to local memory. The operating system kernel is kept in local memory. A private-write area is included in the shared memory space in the memory modules to allow functions such as software voting of state information unique to CPUs. All CPUs write state information to their private-write area, then all CPUs read all the private-write areas for functions such as detecting differences in interrupt cause or the like.

Abstract: This invention discloses an axial sealing mechanism for axially sealing an orbiting scroll (20) and a fixed scroll (10) of a scroll type compressor. The compressor includes a driving mechanism (54) for driving the orbiting scroll in an orbital motion and a block member (30) fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block member and the fixed scroll define an intermediate chamber (40) in which the orbiting scroll is disposed. The intermediate chamber is divided into a first (41) and second chamber (42) by an end plate (21) of the orbiting scroll. A first conduit (71a, 71b), which is sized to produce a pressure throttling effect, links the second chamber (42) and the discharge chamber of the compressor to increase the pressure in the intermediate chamber. A second conduit (81a, 81b), which also is sized to produce a pressure throttling effect, links the second chamber (42) to the suction cham­ber (80) of the compressor. During operation of the compressor, the second chamber is maintained at an intermediate pressure without pressure fluctuation due to the pressure of the first and second conduits. This intermediate pressure provides a constant urging force against the orbiting scroll to urge it against the fixed scroll to obtain a good axial seal between both scrolls without decreasing the durability of the driving mechanism and the rota­tion preventing mechanism.

Filed: 1990-03-27
Abstract: The improvements are applicable to the mound breakwaters (1) which are usually built with a core (3), some filter layers (4) and an armour (5). The armour is the basic element used to proted the general structure from breaking waves. The proposed improvements involve doting the breakwater structure with higher reliability and resistance. This is achieved by increasing the thickness of the armour layer (5) in the zone where, depending on the tide or storm surge, the mean sea levels (6) and (7) cross the external profile (8) of the armour (5). The greater armour thickness is a reinfercement (10) with concave internal profile facing the sea. This internal profile may be augular, truncated, curved etc. However, the external profile (8) of the armour (5) is uniform. 
     Said reinforcement (10) of the armour (5) gives to the general structure of the mound breakwater (1) an optimun damage function. It also improves the response in comparison with conventional mound breakwaters, "S shaped" breakwaters, and "Berm type" breakwaters.
