Title: Thermal transfer color printer and a method relating  thereto
Inventor: YANA MASASUMI
IPC: B41J2/32
Filed: 1983-04-14
Granted: 1986-10-28
Abstract: THERMAL TRANSFER COLOR PRINTER AND A METHOD RELATING THERETO According to the invention, a printer includes an elongated ther-mal printhead and a carrier drive means for transporting a multi-color ink carrier in a first direction and a medium drive means for trans-porting a record medium, in the same direction and rate, contiguously over the head. The printhead has a row of thermal elements, each of which may be energized to transfer a particular color ink onto the medium as the carrier sheet moves over the head. Various transfera-Me color inks form areas which are arranged in equal color lengths along the length of the carrier sheet. Each respective color area extends transversely along the width of the sheet and are alternately and successively arranged along the length of the carrier sheet. The printhead is selectively forced into contact with the carrier sheet and record medium as they advance at the same rate by means of the carrier and record drive means. The record drive means also tran-sports the record medium sheet in a second direction, opposite to the first direction, one color length while the printhead is disengaged fro m the carrier and record medium. This permits superimposing of color patterns for creating greater color hues and color ranges. The movement of the record medium in the second direction occurs at a higher rate than the transportation of the record medium in the first direction.

Abstract: SYSTEM FOR PROVIDING SHORT-TERM EVENT DATA AND             LONG-TERM TREND DATA            ABSTRACT OF THE DISCLOSURE           The system comprises first and second input circuits for receiving first and second parameter signals, respectively, from a patient monitor and producing first and second data signals.  The first and second signals may be ECG and respiration signals, respectively.  Each of the signals is passed directly to a switching circuit, and also passed through a time delay circuit which provides a time delay represen-tation of the signal to the switching circuit.  Also, the first signal is passed to a rate circuit which provides a rate signal indicative of the frequency of the first signal to the switching circuit.  The switching circuit is operative to selectively connect the real time signals, time delayed signals or rate signal to an output circuit depending on the mode of operation of the system chosen.  The output circuit can be connected to a strip chart recorder for providing a permanent readable record of the signal selected by the switching circuit.

Abstract: RADIO RECEIVER Abstract of the Disclosure A radio receiver for frequency modulated signals in which direct conversion techniques are used to provide zero I.F. quadrature baseband signals I & Q.  The I & Q signals are limited (11,12) to form square wave signals and pulse forming networks (13,14) derive pulse sequences the frequencies of which represent the polarity changes in the square wave signals.  Each square wave is multiplied (15,16) by the pulse sequence derived from the other square wave to produce a unipolar pulse train.  The two unipolar pulse trains are combined (17) to give a digital output signal the frequency of which is equal to the sum of the frequencies of the two pulse trains.  Low pass filtering the output signal produces a simulation of the original baseband modulation.

Abstract: ABSTRACT OF THE DISCLOSURE    A radio communication control system for a lead unit and a plurality of remote units is disclosed.  The system has a protocol for establishing a communication link between the lead unit and the one or more remote units in the system which prevents any of the units in that system from processing messages or commands from other units in other train systems or processing messages or commands originating from units within a train system which are addressed to other units within the system.  The communication system also includes a communications channel contention system for minimizing the probability of multiple units transmitting on the common communication channel at the same time and for insuring that the highest priority communications in each train are transmitted first in time measured from the end of the latest transmission on the radio communications channel.  The invention also includes apparatus for verifying the establishment of the communications link by means of signaling through the mechanical coupling in the train and monitoring the radio response.   The invention further includes an improved flow rate sensor for use in a remote unit for determining when significant air flows occur into the brake pipe of the remote unit.  The invention further includes an air pressure regulation system which prevents the fluctuation of the air pressure in the equalizing reservoir of the lead and remote units consequent from either leakage or change in the ambient temperature.

Abstract: ABSTRACT OF THE DISCLOSURE A self-checking shared encoder/decoder circuit 161 for use with a Reed-Solomon coding scheme of an optical disk storage system.  The optical disk system  (20)  includes a drive adapted to permanently store data on a removable platter (44).  Prior to recording a data byte on the platter, the data is encoded with a Reed-Solomon code. When  the data  is read  from  the  disk,  it  is  decoded  and  error correction  syndromes  are  generated  with  ECC  generation  circuits (164).   A plurality of syndrome buffer  registers are provided  in order  to allow  several of  the error  correction functions  to be carried out in parallel.   Syndromes that are detected to comprise all zeros are used to simplify the error correction processes beyond the  normal  processes  used.   The  same  circuitry  is  shared  for performing  the  encoding  and  decoding  functions.   This  circuitry includes independent sets of a RAM (165), coupled to one input of an exclusive OR (modulo two sum) adding circuit (177).  The output of the adding circuit is fed back to an input of the RAM (165).  Two multiplier circuits are coupled to the output of the RAM (165).  A product of one is  tied to one  input of  the modulo two addition circuit  (172).   The product of  the other  is combined  in another module two addition circuit (173) with similar products from other sets, and the resulting combination signal is selectively connected to the other input of the modulo two addition circuit (172), along with data to be recorded on the platter,  or data read  from the platter.

Abstract: LASER-FIBER POSITIONER            Abstract of the Disclosure To position a light output device such as a laser diode relative to a light input device such as a waveguide so as to obtain maximum coupling of light, light is launched into one end of the fiber and is detected at a remote part of the fiber where a corresponding electrical signal is generated.  Positional information contained in the signal is used to reduce misalignment between the waveguide and laser by manipulating a positioner attached to the fiber.  Since there is usually some slight movement of the fiber as an anchoring epoxy bead cures, it is necessary to move the fiber within the curing epoxy and it is advantageous if the position at which the positioner contacts the fiber is at the same site as the epoxy bead.  By the invention, the positioner is attached to the fiber using a wax or similar material so that as the epoxy cures, it does not cure in contact with the positioner.  When the epoxy is fully cured, the wax is melted and the positioner withdrawn.     - i -
