A combinational static CMOS logic circuit for providing a plurality of basic two-input logic functions with reduced complexity and integrated circuit area. The combinational static CMOS logic circuit provides either a NAND or an XOR output at a first output terminal and a NOR output at a second output terminal. A configuration input terminal is utilized for selecting between the NAND or the XOR output being provided at the first output terminal. In an alternate configuration, the combinational s...

An apparatus and method for synthesizing a combinatorial library comprising a plurality of chemical compounds such that the chemical composition of each compound is easily tracked. The library compounds are synthesized on solid-phase supports, which are spatially arranged in frames during synthesis according to a predetermined protocol, such that each solid-phase support passes through a series of unique spatial 2D or 3D addresses by which the chemical composition of each compound may be determi...

A fast error diagnosis system and process for combinational verification is described. The system and process localizes error sites in a combinational circuit implementation that has been shown to be inequivalent to its specification. In the typical case, it is not possible to identify the error location exactly. The invention uses a diagnosis strategy of gradually increasing the level of detail in the analysis algorithm to ultimately derive a small list of potential error sites in a short time....

A combinational chair, recliner and typing stool including a base frame, a seat fixedly mounted on a fixed panel, a first linking member, a second linking member, a first adjusting rod, a fixing member fixedly mounted on a fixed panel, a supporting rod having an intermediate portion pivotally connected with the fixing member, a backrest rigidly mounted on an upper end of the supporting rod, a knee support fixedly mounted on a pair of fixed members, a first connecting member, a second connecting ...

A combinational weighing machine has articles delivered to a dispersion feeder, distribtuted therefrom to a plurality of weigh hoppers through independently driven radial feeders, and weighed such that a combination of weigh hoppers can be selected and their contents can be discharged together. Vibrations of each radial feeder are controlled by parameter values which are calculated on the basis of the parameter values previously set therefor and the weight of the articles in the corresponding we...

A combinational weighing or counting apparatus for performing a combinational calculation of measured weights or number of to-be-weighed articles M measured by a plurality of weighing hoppers 10 to determine a combination which gives the weight or number falling within a permissible range. This apparatus includes a mode selector 38 for setting the apparatus to one of weighing and discharge modes, and a mode control 39 for controlling the apparatus on the basis of one of the weighing and discharg...

A combinatorial library composition and method for using the library to construct oligomers effective to bind to a selected ligand is disclosed. The library composition includes at least two sets of ar oligomer libraries, each library set having selected oligomer subunit positions filled by known subunits, and other subunit positions containing permutations of subunits. In the selection method, oligomers from each library set are identified, and a new permutation library formed of subunits corre...

A combinational weighing or counting apparatus of a type in which the weighing hopper (30) once removed and subsequently remounted or the weighing hopper (30) from which the relatively large appendant has been separated naturally by gravity can be automatically reset to resume its participation in the combinational calculation. The apparatus includes an automatic resetting means (56) excludes, when the removal of the weighing hopper (30) is detected, weights detected by respective weight detecti...

A combinational weighing or counting apparatus designed to increase the probability of selection of combinations. This combinational weighing or counting apparatus includes a plurality of weighing hoppers (6.sub.i), and a plurality of driving feeders (3.sub.i) for supplying articles (M) from an upstream side towards the corresponding weighing hoppers (6.sub.i) when the driving feeders (3.sub.i) are driven. In this combinational weighing or counting apparatus, the value at which the probability o...

A combinational weighing machine has weigh hoppers for weighing articles, a dispersion feeder for dispersing articles to be weighed, supply troughs for supplying articles from the dispersion feeder to the weigh hoppers and a control unit for controlling overall operations of the machine inclusive of combining weight values outputted from the weigh hoppers and discharging articles from selected ones of these weigh hoppers. The weighing machine is placed inside a washing device which forms a close...
