Abstract: A pattern-matching system, such as of the RETE type, is updated. The updating operation is generalised to operate with correct match results for generalized RETE networks (ones where join nodes may have either predecessor be another join node), and for arbitrary partial update state, and uses stop nodes designating how far update operations have progressed for particular update tokens (designated suspended tokens) at any particular time. The updating operation consists of the follow-­ing steps: First, all tokens only partially updated through the network are shadowed, in that the partial result memories associated with the stop nodes are put into the state that exists or existed before the suspended tokens arrive at the stop nodes. Then for each suspended token, it is pushed to resume nodes connected as RHS (or LHS) inputs in a descending order of resume nodes. The descending order is determined among sets of resume nodes where one node is reachable from the other, either in an upwards or downwards direction. Following one token's push to RHS (or LHS) connected resume nodes, that token is unshadowed in the stop node's associated result memory, and that token is then pushed to resume nodes connected as LHS (or RHS) inputs, in an ascending order of resume nodes. Tokens are pushed from alpha top nodes when the stop node is in the alpha portion of the RETE network, to the suspended portion of the successor nodes of the alpha top node.

Abstract: A reflective-type photoelectric switch projects emitted light from a light-emitting element toward a detection zone by a light-projecting optical system, and guides reflected light from an object to be detected in the detection zone to a light-receiving element by a light-receiving optical system. A special optical element is used in part of at least one of the two optical systems. The optical element functions to diverge light in a direction parallel to a plane containing the optic axes of the light-emitting and light-receiving elements, and condense light in a direction perpendicular to the same plane. As a result, it is possible to detect, with excellent sensitivity, both an object which is far from the switch and an object very near the switch.

Abstract: A write-once-read-once batteryless token stores access data using fuses (34) similar to those found in programmable fuse link devices. These fuses indicate the status of a particular bit in either of two memory arrays (30, 40). An intact fuse indicates that a bit is a logical zero, and a blown fuse indicates that a bit is a logical one. The process of reading a particular bit in either array causes the destruction of the corresponding memory cells in both arrays before the data from the selected cell becomes available to the reading device. The memory bit cells are destroyed by blowing the bit fuse during the read cycle.

Abstract: In RDS car radios, a station-finding run is automatically carried out when the received quality drops below a predetermined limit and the alternative frequencies can also not be received with adequate quality or if there are no alternative frequencies, as is the case with local transmitters. It is the object of the invention to suppress a station-finding run in the case of short-time local disturbances. This object is achieved in that, after the alternative frequencies have been checked, no station-finding run is started if they, too, are not suitable for reception and instead the transmitter last tuned in is tuned in again and remains tuned in for a predetermined time.

IPC: G11B21/08

Abstract: The present invention utilizes the output of a voltage regulator to control the drive voltage to the stepper motor (14) driven transducer positioning system (15, 16, 19a, 19b, 22, 23, 21, 29 20). This technique will significantly reduce the access time. More specifically, in this invention, the output of a digital-to-analog converter (DAC) (50) is used to control the output voltage level of a voltage regulator circuit (Figure 4) which supplies the voltage of the stepper motor drive transistors (Q3 58; Q2 63; Q1 54). In order to optimize the drive voltage output from the voltage regulator to the stepper motor (14) for each disc drive, a series of seeks is performed using identical starting and target tracks. As each seek is performed, the input to the DAC is incremented by a microprocessor (11) causing the stepper motor drive voltage to be increased in one milli-volt increments. A ring detector (32) (which provides an output count of the number of target track crossings by the transducer (10) before the transducer settles on the target track) monitors the settling time of the head over the center of the target track. The data identifying the voltage regulator output which results in minimum ring-out count is stored and used from then on for that stepper motor disc drive system as the optimum access tuned voltage. This data will be applied by the microprocessor to a DAC, and output from the voltage regulator to the stepper motor drivers during each stepping sequence. 
     Typically, this tuning process is originally accomplished when the disc drive is first powered on and is part of the normal power-on recalibration routine. The disc drive could also be returned on   command or by any other interrupt routine parameter such as time or temperature change. 
     Alternatively, the calculated optimum drive voltage could be stored on a non-user accessible track of the disc surface of the disc drive, and automatically accessed as part of the power-on rountine for the disc drive.

Abstract: This invention relates to an over-write capable magnetooptical recording method and, more particularly, to a pit position recording method, and a recording apparatus used therefor. In a method and apparatus of this invention, a laser beam intensity is pulse-modulated between high and low levels according to data to be recorded. The modulated laser beam is radiated on a recording medium under the presence of a bias field, thus performing over-write capable magnetooptical pit position recording. In this case, a high-level emission time of the laser beam is shortened at the inner portion of the medium, and is prolonged at the outer portion. Meanwhile, a low-level intensity of the laser beam is decreased at the inner portion of the medium, and is increased at the outer portion, thereby increasing a C,N ratio upon reproduction.

Abstract: A power control system includes a voltage follower circuit 17 which may be interposed between a load power control circuit 19 which adjusts the level of power applied to a load, and a variable impedance 10 whose internal impedance prescribes the desired level of power. A feedback voltage from the output of the voltage follower circuit is compared with a corresponding voltage across the variable impedance and the difference between them is used to drive the output voltage 27 of the voltage follower circuit toward the input voltage 11. The voltage follower circuit permits control by a single variable impedance of many more load power control circuits than a single variable impedance can normally handle, and without appreciably affecting the power level as a function of the impedance level. This circuit is particularly useful in a system for controlling the level of light received from fluorescent light fixtures controlled by electronic ballasts.

Abstract: A store through cache environment managed exclusively grants exclusivity on a large granularity basis. A cross-invalidate is realized for all changed lines via a single transmission when exclusivity is released. A dynamic table that operates in conjunction with a directory look-aside table (DLAT) determines a number of pages that can be held exclusive simultaneously. For adequate operating speed, the special table must be either fully associative or at least set associative. Alternatively, the table can be incorporated into the DLAT. Each DLAT entry is also extended to include a set of "resident" bits and a "valid nonresident" bit. When exclusivity is released, the set of local change bits is broadcast to all processors. Upon receipt of such broadcast, the appropriate action is to change the "valid nonresident" indication to read-only and to clear residence bits whose corresponding local change bit is set.

Abstract: An air gap controlling system for a linear motor wherein a comparatively small air gap can be assured between a truck-carried element and a ground-mounted element to assure a high efficiency of the linear motor and construction for driving such ground-mounted element is simplified. Driving means is provided on each truck for driving a truck-carried element of a linear motor to be displaced upwardly or downwardly to adjust an air gap between the truck-carried element and an opposing ground-mounted element which also constitutes the linear motor, and an aimed value of the air gap between the two elements is set in response to a running speed of a velocity of the truck and a truck position signal representative of a position of the truck. At the first truck, the driving means is controlled so that the air gap may be equal to the air gap instruction value which is a rather high value. An air gap aimed value is set similarly for each of the trucks succeeding to the first truck, but is corrected so that an air gap of a succeeding truck may be controlled to a low value so as to assure a high efficiency of the linear motor.
