Abstract: A clustering and association processor is disclosed for correlating sets (12) of two-dimensional data points (14). Clustering is performed by treating each data point (14) as a mass subject to gravitational attraction by other data points (14). The data points (14) are permitted to move in data space until all data points (14) in particular regions (16) of the data set (12) fall into a single point, or centroid (18). Individual data points (14) and correlated regions (16) of successive data sets (12) are then correlated by means of a resonant descent technique, which determines the distance and direction of individual data points (14) from a chosen data point. The processor then matches a pair of two data points (12) with the chosen data point which are equidistant and collinear with the chosen data point.

Abstract: A semiconductor input protection device is disclosed which comprises a well type punch-through transistor con­sisting of a pair of parallel-opposed well layers through intermediation of a field oxide film, one of which is con­nected to an input terminal and the other to a reference potential. The device further comprises an impurity diffu­sion layer resistance with an end thereof connected to the input terminal. The lower limit distance between the opposed sides of the well layers to each other and the channel stop­per is set to be smaller than that between the channel stopper and the input terminal-side well layer in the area where the latter and the impurity diffusion layer resistance intersect. The two lower limit distances depend on punch-­through voltage, the width of the depletion layer in the well layer at applied punch-through voltage, and the junc­tion disruptive strength of the well layer.

Abstract: Print heads are formed with spaced subheads having nozzles such that all of the lines or pixel rows on a print medium such as a sheet of paper are printed by scanning of the print head along the face of the sheet. The head structures include three subheads, each having nozzles for printing one or more adjacent lines with the subheads being spaced the same number of lines apart as the number of lines each prints; and three subheads spaced the equivalent of seven lines apart, each subhead having three nozzles spaced at the equivalent of alternate lines. The heads are advanced between scans by an equivalent number of lines generally equal to the number of nozzles in the head, whereby all print lines are addressed only once. Apparatus for printing includes the use of pointers in registers to keep track of head structure and location on a print medium for calculating print addresses. A partial page memory is used which wraps around to the beginning from the end. A positive printer carriage position encoder uses an index marker located in the middle of a strip of incremental markers. Sensing of the index marker resets an up/down counter with a value that gives a positive value for all count conditions.

Abstract: A data structure includes data indicating a set of strings of character or phoneme candidate identifiers. Each identifier indicates a machine discriminatable candidate type, and the data are accessible to determine whether a string of candidate identifiers is in the set. To produce the data structure, the set of strings is obtained using a list of words. All possible strings up to a given length are obtained, and those that have a high probability of being one of the words are retained. Also, the words are expanded into strings by using probable candidate identifiers for each character or phoneme. If necessary, the number of candidate types is increased or decreased to obtain a satisfactory set of strings. The data structure can include information relating to each string in the set; for example, it can be a finite state transducer with data units, each including a candidate identifier and a character or phoneme identifier, so that the characters or phonemes of a word can be obtained from it. A processor receives a string of candidate identifiers from a candidate discriminator and searches the data structure for the identifiers that occur in the string. If a search succeeds, data relating to the matched string are obtained, such as a word it is likely to be or an identifier of the string. If the string is likely to be more than one word, one of the words is selected and its characters or ph,one,mes are provided as output. A system can include parallel recognition units, each with a respective data structure. The sets of strings can correspond to words with features such as' part of speech font speaker, a language, or a specialized vocabulary. 
     A results processor can receive the results from the recognition units and use them to obtain the characters or phonemes of a word that is likely to be the string being recognized.

Abstract: An apparatus for controllably feeding a particulate material, and particularly silicon material into a crucible, comprises a drum (10) mounted for rotation about an axis tilted at an acute angle with reference to the horizontal. At least one cavity, a portion of which is formed in the inner surface of the bottom wall (12) of the drum, extends from about the outer periphery of the bottom wall at its one end towards the center thereof at its other end. At one of its ends, the cavity communicates with an aperture (17) in the bottom wall. A feeding tube (20) having an outlet port supplies the material into the cavity and is so positioned in relation to the drum that the outlet port directs the material into the cavity only when the cavity is in a rotational position in which its end with the aperture is elevated with respect to a horizontal plane above the other end of the same cavity and pours the material into that portion of the receiving cavity which is remote from the aperture. The flow of the material is interrupted when its level above the cavity reaches a predetermined level. Upon rotation of the drum, the cavity is filled with the material fed from the tube during the rotation of the drum through a first angular portion of its rotation when its aperture is disposed above the already filled portion of the cavity and is emptied to discharge the material by gravity during the rotation of the drum through a second angular portion of its rotation when the aperture is below the filled portion. The feeding rate of the material being discharged is controlled by the rate of rotation of the drum.
