摘要： A synchronous sampling data detection channel includes a data transducer head (26) positioned by a servo-controlled actuator (32) over a recording track of a rotating data storage disk (16), a preamplifier (28) for receiving electrical analog signals magnetically induced by the data transducer head (26) from flux transitions present in at least the servo information field, a digital sampler (46) for sychronously sampling the electrical analog signals to produce digital samples, and a Viterbi detector coupled to receive digital samples from the synchronous sampling data detection channel for decoding 1/4 T coded wide biphase servo information patterns as maximum likelihood servo data sequences, wherein the wide biphase magnet patterns are arranged e.g. as ++-- magnet patterns for a binary zero information value and --++ magnet patterns for a binary one information value.

摘要： A hydrodynamic bearing journaling a shaft (3) includes a rotatable bushing journaling the shaft (3) and thrust plates (4) on the shaft (3) at opposite ends of the bushing (7). The bushing (7) is encased in a cylindrical sleeve (6). Lubricant containing clearance spaces (11,18,19,21) are formed between the shaft (3), bushing (7), sleeve (6), and thrust plates (4). One or more internal helical passages (20) are formed between the bushing (7) and sleeve (6) and open into the axial ends thereof adjacent to the thrust plates (4). An internal radial chamber between the bushing (7) and sleeve (6) opens into the helical channel (20) through radial ports (14) for providing lubricant between the journal bearing and the shaft (3) and thrust plates (4).

摘要： Frame processing apparatus, and a related method for its operation, for use in a station connected to a token ring network, to ensure rapid stripping of frames from the network without reference to source addresses in the frames, and in spite of the possible presence of extraneous no-owner frames on the network. The adverse effects of extraneous no-owner frames are avoided by any of three techniques. First, transmitted information frames are preceded by a start strip delimiter frame and followed by an end strip delimiter frame. The process strips all incoming frames (except tokens and ring initialization frames, which are specially handled), but does not count the stripped frames until the start strip delimiter frame is detected. Therefore, extraneous frames preceding the transmitted information frames will be stripped but not counted, and all of the transmitted frames will be stripped. In another approach, an estimated stripping time is used to terminate stripping. Frame counters are not then needed and extraneous frames will be stripped prior to the desired information frames. A third approach is to preset the transmitted frame count to some selected value, so that more frames will be stripped than were transmitted. Thus, preceding extraneous frames will be stripped, but the end strip delimiter will still terminate stripping and preclude overstripping.
