Abstract: A differential unit (1,30,40) has axially aligned helically toothed output gears (11,12;51,54,57) of different diameters to provide an unequal division of the input torque, in meshing relationship with two sets of intermediate gears (22,24;32,34;60,61) which mesh together and are rotatable on axis parallel to the output gear axis. The gears (61) of one set of intermediate gears mesh with concentric internally and externally toothed output gears (54,57) to provide alternative outputs at different torque division rates. Slip within the unit can be opposed by frictional coating on the gears and/or on the housing by which they are carried and/or by a damping fluid which may be an electro-rheological fluid.

Abstract: The invention pertains to a circuit for controlling the power to a plurality of sense amplifiers used for sensing data on data lines in an array of floating gate storage cells, wherein the data stored in the array is sensed at regular intervals. The circuit includes a first plurality of data paths through the array, and a second data path containing replications of all necessary circuit elements in the first plurality of data paths to assure that the data delay through the second path equals or exceeds the maximum delay in any of the first plurality of data paths. A clock (CLK) is used to provide an initiation signal which starts the propogation of input data through the array. The control circuit of the invention reduces the power consumption of the sense amplifiers because they are powered only during the duration of data transmission, but are otherwise powered down.

Abstract: A correspondence relation between a structure of a bi-level pattern A and a structure of a bi-level pattern B is statistically learned by use of a learning high-density image. The bi-level pattern A forms a partial region of a low-density character and line image except a screened dot image. The bi-level pattern B forms a corresponding partial region of a desired high-density image. A judgment is made as to whether the low-density image is equal to or different from a screened dot image. Reference pixels are selected from the partial region of the low-density image. The low-density bi-level pattern A is converted into the high-density bi-level pattern B on the basis of a result of the learning by use of the selected reference pixels when the low-density image is different from a screened dot image. A pixel of the low-density image is repeated to convert the low-density image into the high-density image when the low-density image is equal to a screened dot image.

Abstract: The offset hashing lookup table of this invention locates entries in a lookup table faster than previously known methods that were as space efficient, while requiring less space than previously known methods that were as fast. 
     In the offset hashing lookup table of this invention, the data of information is sorted in a first vector of entries according to the hash value of a key for each entry in the table. The possible range of hash values ranges from 0 to the number of entries minus 1, (N-1). In addition, an offset vector is utilized which has the same number of entries as the first vector of entries. The offset vector is constructed such that at any given position "i" from 0 to N-1 within the offset vector, the sum of the contents at that position "i" and "i" is an index of the first entry of the first vector which has a hash value greater than or equal to "i". In the first vector, all the entries with the same hash value are contiguous, and bounded by the offsets found in the offset table at position h(key) and h(key)+1.

Abstract: Method of forming conductive members on a substrate (10 - Fig. 1A) of GaAs. Silicon (13 - Fig. 1B) is placed on the substrate surface (10) in the desired pattern of the conductive members. The substrate (10) is exposed to a gaseous atmosphere containing WF₆. WF₆ is reduced by the silicon causing tungsten to selectively deposit on the silicon but not on the exposed GaAs. The substrate (10) is given a rapid thermal annealing treatment which causes the silicon-tungsten elements (13, 14 - Fig. 1C) to form conductive members (13-14 - Fig. 1D) having a silicon rich layer at the bottom, an intermediate tungsten silicide layer, and a tungsten rich layer at the top. The conductive members form ohmic contacts with underlying heavily doped GaAs and rectifying Schottky barrier contacts with underlying lightly doped GaAs.

Abstract: The machine comprises essentially a substantially belt-like endless conveyor (6) provided with plates (16) having cells to which the bodies (C) to be wrapped are supplied individually. The cells with the bodies (C) housed therein are covered by a wrapping sheet (F) which is supplied continuously (26) and is subsequently cut (30) to form an individual wrapping sheet portion for each body (C). The unit constituted by each body (C) and its respective wrapping sheet portion is turned over and transferred to a drum (9). A thrusting action exerted on the body (C) moves the body from the conveyor (6) to the drum (9) which is provided with gripping jaws and associated folding members. An intermediate, generally tubular wrapper with two end parts and a central part in which the body is situated is thus formed. Rotary pincers provided with pairs of clamping fingers act on these two end parts to form bow-like twists.
