Abstract: A buffer solution is sampled from a buffer solution vessel (52) and is dispensed into a reaction vessel (12) on a reaction table (10) by first sampling/dispensing means (100), and a specimen containing an antigen or antibody to be measured is sampled from a specimen vessel (202) and is dispensed into the reaction vessel (12) by second sampling/dispensing means (140). A reagent containing insoluble carriers to which is bonded an antibody or antigen that specifically reacts with the antigen or antibody in the specimen is sampled from a reagent vessel (92) and dispensed into the reaction vessel (12) by third sampling/dispensing means (142). The entire reaction table (10) is shaken continuously during mixing of the buffer solution, reagent and specimen, and the reaction vessel (12) is maintained in an isothermal state. A stable antigen-antibody reaction in the resulting reaction solution is thus promoted to form an agglutinate of the insoluble carriers. The reaction solution is sampled from the reaction vessel (12) and dispensed into a sample chamber (160;162) by fourth sampling/dispensing means (144;146). The dispensed reaction solution is tansferred to a detector through which the insoluble carriers are passed and in which a signal is generated based upon a difference in terms of electrical or optical characteristics. The degree of agglutination of the insoluble carriers is obtained as a numerical value, thus making it possible to quantify the antigen or antibody of interest contained in the specimen.

Abstract: A microprocessor (32) periodically tests the status of the stem (40) of the motor operated valve (22), and turns off the valve's motor (24) if certain predefined criteria for the valve stem position and the valve stem load are satisfied. A position sensor (46) provides a valve stem position signal and a predicted stem position signal is computed. The current and predicted positions are compared with a preselected target position. A stem load sensor (48) provides a current valve stem load signal, a predicted stem load is computed and the current and predicted loads are compared with a preselected maximum desirable stem load. 
     When the control system is being used to fully open and fully close a gate valve, the control logic can use either a predicted position criterion or a predicted stem load criterion to determine when to turn off the valve motor (24). When the control system is being used with a flow control valve, the use of a predicted position criterion minimizes overshoot problems which would cause the motor (24) to be reversed one or more times while moving to a target position. 
     A motor load sensor (70) allows periodic measuring of the actual load on the motor (24). The motor is turned off if the measured motor load exceeds any one of a plurality of preselected maximum motor load values for a corresponding predicted period of time.

Abstract: An anti-lock braking system incorporates a copy valve (6) adapted to ensure that the behaviour of a brake (4) on one rear wheel of a vehicle is copied by the brake (5) on the other rear wheel when an anti-lock situation arises. For example, a single copy valve (6) may be incorporated in the braking circuit for the rear wheels of a vehicle of which the behaviour of the brakes (4, 5) is controlled by a single modulator (24). In another construction, two such copy valves are incorporated in a twin assembly of a braking system of the 'X' split type. In such a construction both rear wheel brakes respond to operation of one of a pair of modulators (34, 35), each responsive to signals from a speed sensor on a respective front wheel of the vehicle. The or each copy valve incorporates first and second pistons (12, 13) which are relatively movable in response to differential pressures from the pressure spaces (2, 3) of a master cylinder (1) in order to control operation an isolating valve (17).

Abstract: An electric motor (10) is braked by sensing the polarity of voltage (V ab ) of the alternating electricity for powering the motor and sensing the polarity of the voltage (V a , V b , V c ) induced in the motor by the back electromotive force. When these polarities are opposite the electricity is applied to the motor (10) to generate a braking torque. The application of the electricity is stopped a given interval after it begins to be applied during consecutive voltage cycles. This interval is derived from the time period between when braking commenced to when the electricity was applied during consecutive cycle.

Abstract: A print data generator uses bit-mapped font data to modify bit-mapped image data by shifting a series of font words followed by an all-zero word through a bit offset S and performing an operation on those bits of image words and shifted font words that correspond to enable bits in converted mask control words. To create the converted mask control words, the print data generator has a mask control data source for generating source mask control words consisting of S disable bits followed exclusively by enable bits, and a mask control data converter that passes the first source mask control word through unaltered, substitutes all enable bits for the next (N - 2) source mask control words, and inverts the Nth source mask control word. By generating and converting mask control words automatically, the print data generator creates print data rapidly without overloading its controller.

Abstract: This invention discloses an axial sealing mechanism between an orbiting scroll 10 of a scroll type compressor. The compressor includes a driving mechanism 50 of which a drive shaft 51 is operatively linked to the orbiting scroll to make the orbital motion of the orbiting scroll. A block member 30 is fixedly attached to the fixed scroll to define a chamber 40 in which the orbiting scroll exists. The chamber 40 is divided into first 41 and second 42 chambers by an end plate 22 of the orbiting scroll. A rotation preventing mechanism 60 for preventing rotation of the orbiting scroll is disposed within the second chamber. A first passage 71 having throttling effect links a discharge chamber 70 to the second chamber 42. A second passage 81 having throttling effect links a suction chamber 80 to the second chamber 42. During operation of the compressor, the second chamber is maintained at an intermediate pressure without pressure fluctuation. Thereby, the orbiting scroll is urged to the fixed scroll with a constant force to obtain a good axial seal between the scrolls, but without pressure fluctuations decreasing the durability of the driving mechanism and the rotation preventing mechanism.

Abstract: An expression comprising conditions is evaluated based on values of data elements presented to a network of a kind in which the conditions are represented by nodes and the relationships among conditions in the expression are represented by links among the nodes, by storing information that identifies which conditions represented by at least some of the nodes have been satisfied by the values of the data elements, and testing the stored information in accordance with the expression as a basis for evaluating said expression. In a second aspect, an expression that comprises conditions which pertain to possible values of data belonging to categories of data is evaluated based on actual values of data presented to a network of a kind in which the conditions are represented by nodes, by identifying a category of data for which values need not occur in the network in order for a condition that requires a value in the category to be provisionally satisfied, and causing the node that represents the condition to indicate that the condition is provisionally satisfied even when no values in the identified category occur in the network.
