Abstract: GRANULAR DETERGENT COMPOSITIONS CONTAINING      ORGANO-FUNCTIONAL POLYSILOXANES                         ABSTRACT             Granular built detergent compositions containing additive levels of  organo-functional  polysiloxanes are  disclosed.   The  siloxanes  are derived from poly-di-short-alkyl siloxanes by substituting part of the alkyl  moieties  by   specific  organo-functional   groups,   preferably amino-groups, with the proviso that the degree of substitution is in the range  from 0.01  -  0.7.   The  granular  detergent  compositions  herein unexpectedly provide through-the-wash softening benefits comparable to what  can be  obtained  from  the  utilization  of  conventional  cationic rinse-softeners.    An   additional   benefit   originates   from   the "dry-softening"  feel  of  the  composition  herein  as  compared  to  the "greasy" feel conferred by conventional cationic rinse softeners.

Abstract: ABSTRACT A multi-channel broadcasting system in which encrypted data signals are transmitted in either or both directions between a central terminal and any one of a number of subscriber terminals. When a subscriber selects a secure channel dedicated to the transmission of encrypted data, the terminal is temporarily connected to a further channel dedicated to the transmission of encryption and/or decryption information signals. The transmitted encryption and decryption information signals are stored and used to encrypt and decrypt the data signal to be transmitted after the terminal is switched back to the selected secure channel. The stored encryption and decryption information signals are subsequently canceled.

Abstract: ABSTRACT      Method and apparatus for making high resolution color prints using ink jet techniques.  The method and apparatus of providing for precise control of the number of droplets of printing fluid which is deposited in a pixel on recording paper.  The precise control is achieved by incremental control of the print pulse width or time duration.  Further precision can be obtained by synchronizing droplet formation with for example, the leading edge of the print pulse.          The number of droplets charged during the time duration of the print pulse are the number of droplets which impinge on the paper and at the pixel location.          The number of droplets creates therefore a color density.  Use of a plurality of nozzles and ink colors will permit the production of very high resolution and high quality color prints.

Abstract: Abstract:        The present invention relates to a crank angle sensor.  The crank angle sensor comprises a magnetic recording medium rotating synchronously with a crank shaft on which magnetic signal are recorded and a magnetic sensor is provided opposite to the magnetic medium.  The magnetic signals are detected to produce rotational angle information.          The magnetic recording medium is divided into plural tracks, for example, an angle track, and a cylinder track.  On the angle track, unit magnetic poles serving as the magnetic signals are provided in a pitch P corresponding to an angle to be detected.  For each magnetic signal on the cylinder track there is consecutively provided some of the same unit magnetic poles as those in the angle track in the pitch P at locations which are determined by the number of cylinders of the engine. The polarities of the unit magnetic poles on the cylinder track are in the same arrangement as those of the unit magnetic poles of the angle track.  As a result, no magnetic interference occurs between the unit magnetic poles of the angle track and the cylinder track.  The angle signals and the cylinder signals can be obtained with high accuracy.

Abstract: Abstract A high speed monolithic current switching digital-to-analog  converter  (DAC) is provided.   The DAC  includes input level shift clock and data drivers,  differential dual latches,  differential  multiplexers and high speed  current switching cells.  Utilizing complementary clocks at one-half the  input data rate,  data is effectively latched  at  each transition  or  edge of the clock pulse rather than at  only the positive (or negative) going edge of the  clock.   Thus, feedthrough  of the previously unused clock edge and pertur-bation in the DAC output caused by the unused clock edge  is eliminated.
