Abstract: A process for making melamine-formaldehyde microcapsules in an aqueous solution containing a high concentration of a water miscible or water soluble organic solvent is provided. The aqueous solution is prepared and a water insoluble melamine-formaldehyde pre-condensate is dissolved therein by adjusting the temperature and organic solvent concentration of the aqueous solution such that the melamine-formaldehyde pre-condensate is barely soluble therein. A substance to be encapsulated, preferably an oily solution containing a dyestuff precursor, is dispersed into the aqueous solution to form an emulsion, the melamine-formaldehyde pre-condensate being insoluble in the substance to be encapsulated. The melamine-formaldehyde pre-condensate is separated from the aqueous solution onto droplets of the substance to be encapsulated and the self-condensation reaction of the phase-separated melamine-formaldehyde pre-condensate initiated to form capsule walls around the droplets, thereby producing melamine-formaldehyde microcapsules in the aqueous solution containing a high concentration of a water miscible or water soluble organic solvent.

IPC: H03L7/091
Filed: 1993-01-18
Granted: 1998-05-19
Abstract: A modulus counter counts first clock pulses to modulus M and outputs the count value as an m-bit reference signal, M being an integer.  A latch circuit samples and holds the reference signal in response to a trigger signal generated by a trigger signal generator in synchronism with an input signal.  A high-speed counter is supplied with second clock pulses of a frequency higher than that of the first clock pulses and starts counting the second clock pulses in response to the trigger signal and stops the counting in response to a first one of the first clock pulses immediately thereafter.  A data processor converts the n-bit count value of the high-speed counter to n-bit data corresponding to a phase fraction of a phase quantization step in the latch, combines the n-bit data as low-order bits with m-bit data from the latch and outputs the combined data as phase difference data.

Abstract: In a distributed system  ,  such as a  local  area network having a facility for synchronous remote procedure calls and multi-threading,  an interface mechanism for linking client workstations  on  the  distributed  system  with  external switched communications networks is provided.  The interface extends the  remote procedure calling facility beyond the distributed system by classifying the different types of remote procedure calls that can be issued to a switched communications  gateway  in  the  distributed  system,  and permitting the  issuance  of multiple  threads  of  control, according  to  the  type  of  function  the  procedure  call represents.   Related  functions  are  forced to  execute sequentially  at  the  gateway,  while  those  classified  as unrelated   functions   can   execute   sequentially.    The advantages  of  heterogeneity   and  concurrency  of  the distributed  system  are  thus  extended  to  its  switched communications links with external switched networks.

Abstract: A striding exercise device  includes a base having two elongated parallel tracks which curve upwardly in a constant radial arc, and two footskates which are rotatably  supported  on the  tracks  for  reciprocating movement thereon.  The radial arc generally corresponds to the natural swinging arc of a human leg as the leg pivots about the hip.  When the operator stands on the footskates and reciprocates the footskates back and forth along the upwardly curved tracks, the operator's torso is maintained in a stationary and balanced position over the base.   The reduction in torso movement substantially eliminates strain on the leg joints, particularly the knee and hip joints, caused by up and down movement of the torso  and  further  substantially  eliminates  back strain caused by reaching and bending at the waist.

Abstract: Electronic signature apparatus and method provide an electronic signature that can be created only by a signer, but cannot be used for other than the signature object document to be processed, and that can be verified and authenicated as an image. Since the verified result is an image, such as a print of a seal and a signature, the verifier can easily verify the validity of the image. In addition, since a signature image and a signature object document may separately be processed, combined, and decomposited upon decryption, they can effectively be used for a printed signature.
