A computer implemented representation of a circuit design including memory is abstracted to a smaller netlist by replacing memory with substitute nodes representing selected slots in the memory, segmenting word level nodes, including one or more of the substitute nodes, in the netlist into segmented nodes, finding reduced safe sizes for the segmented nodes and generating an updated data structure representing the circuit design using the reduced safe sizes of the segmented nodes. The correctness of such systems can require reasoning about a much smaller number of memory entries and using nodes having smaller bit widths than exist in the circuit design. As a result, the computational complexity of the verification problem is substantially reduced.

A shaft sealing assembly seals a rotary shaft of a refrigerant compressor with a first sealing member, which is a lip seal. The first sealing member has a hollow portion. As the pressure in the interior space of the compressor housing increases, an outer wall surrounding the hollow portion is elastically deformed. Accordingly, a lip portion of the first sealing member receives a tension that weakens a force pressing the lip portion against the rotary shaft. Therefore, the sealing assembly improves the durability of the lip portion and maintains a satisfactory property of the lip portion to follow displacement of the rotary shaft at the same time.
