  • Publication number: 20060181013
    Abstract: A sheet guide apparatus includes a transfer cylinder, delivery chains, and sheet guide structure. The transfer cylinder holds a sheet. The delivery chains hold the sheet received from the transfer cylinder and conveys the sheet along a first convey path which is at least substantially arcuate. The sheet guide structure guides the sheet conveyed by the delivery chains. The sheet guide structure includes a movable guide member and stationary guide member. The movable guide member is movable between positions close to and spaced apart from the first convey path. The stationary guide member is stationarily arranged at a position spaced apart from the first convey path. When the movable guide member is close to the first convey path, a thin-sheet guide surface having a continuous substantially arcuate section is formed by only the movable guide member.

  • Patent number: 6526887
    Abstract: A plate inserting apparatus in a rotary printing press inserts a plate in a leading edge plate clamp of a plate cylinder. The plate inserting apparatus includes a plate holder and actuators. The plate holder holds the plate. The actuators move the plate holder in directions to come close to and separate from the plate cylinder. The plate holder forms a moving track comprised of at least a first straight portion and a curved portion. The first straight portion extends in a direction to insert the plate held by the plate holder into the plate fixing unit. The curved portion is connected to a counter plate cylinder-side end of the first straight portion to change a traveling direction of the plate holder.

  • Patent number: 5956263
    Abstract: A multiplication, division and square root extraction apparatus which calculates the solutions to addition, division and square root extraction functions by approximation using iteration has a multiplier, an adder-subtracter and a shifter of prescribed bit width connected to a bus. Iteration is conducted by inputting the output of the multiplier to the adder-subtracter or the shifter and returning the result to the input of the multiplier via the bus. A shifter and an arithmetic and logic unit connected to a second bus connected to the aforesaid bus via a switch have a greater bit width than the prescribed bit width and are used for large scale calculations, thus preventing a reduction in processing speed.

  • Patent number: 5485287
    Abstract: A high-speed image signal processing system for encoding an image signal, read out at a high speed, into an encoded signal, and/or for recording a decoded signal obtained through a decoding operation on an encoded signal. The image signal, obtained through a scanning operation on an original document, is sent to an encoder through an image bus. A code bus, provided at an output of the encoder, is connected with an encoded-signal memory for storing the encoded signal. A code transfer unit, for performing input/output operation over the encoded signal and for performing transfer of the encoded signal from the code bus to a system bus, is disposed between the code bus and the system bus. A control unit, performing control over the entire system, and a document management data memory, storing management data for performing management over documents stored in the encoded-signal memory, are connected to the system bus.

  • Patent number: 5125095
    Abstract: A microcomputer system has a microprocessor and a number of independent coprocessors for executing individual instructions according to instruction data sent from the microprocessor. An address bus and a data bus interconnect the coprocessors with the microprocessor. The microprocessor sends instruction data to the coprocessors via the data bus and concurrently sends coprocessor designation data to the coprocessors via the address bus. The coprocessor designated by the designation data reads and reacts to the instruction data while the other coprocessors within the system disregard the instruction data.

  • Patent number: 4888721
    Abstract: A function arithmetic unit which performs elementary operations at high speeds and which enables required memory capacity to be reduced. The function arithmetic unit includes a constant memory which stores a constant that corresponds to the number of successive iterative operations; a controller which causes addition or subtraction in the successive iterative operations; and arithmetic units which receive, as initial values, an argument of an elementary function value to be found and two constants determined depending upon the elementary functions to be found, and which subject these initial values to n iterative operations to produce elementary function values. A further arithmetic unit subjects the elementary function values to multiplication, addition, subtraction, or division, or a combination thereof, thereby to produce the thus obtained value.

  • Patent number: 4736324
    Abstract: The optimum control conditions for a plurality of looms are simply estimated with the use of a trial loom. Hereby, the plurality of looms are operated under a centralized control method. The looms, even if they vary in their respective characteristics, can be effectively operated by correcting standard control data for controlling the looms in response to variations of the loom characteristics. The present centralized control method can save much labor and time to improve productivity of the looms, by properly eliminating elaborate trial weaving processes.

  • Patent number: 4619294
    Abstract: Motor-driven let-off and take-up motions in a loom are controlled by controlling the rotation of a motor for driving warp yarns with a tension control system operating in response to a signal indicative of a target tension and a feedback input signal indicative of an actual tension of the object during a normal operation of the loom, and controlling the rotation of the motor with a feedforward control system during a transient operation of the loom, the feedforward control system storing operation patterns of directions, and speeds of rotation and angular displacement of the motor for respective operation modes and weaving conditions of the loom. At the time of the transient operation, and operating condition of the loom is detected, an appropriate operation pattern is read from the feedforward control system based on the detected operation mode, and the read operation pattern is applied as a control signal to a drive control system for the motor.
