  • Patent number: 11110594
    Abstract: A fine work assistance system is configured such that a parallel link mechanism is used for a slave manipulator activated by a master operation, and a precise motion for microsurgery or the like is performed by remote control. In a slave unit of a master-slave manipulator, the parallel link mechanism with multiple degrees of freedom is used for a link mechanism in which an end effector is movable with respect to a base. Moreover, a tip operation part is driving by a hydraulic driving mechanism such that a plurality of linear actuators supported by the base move one ends of links so as to move the end effector, and the slave unit is activated in response to a user operation on the master unit. This achieves the precise motion of the end effector and causes the end effector to perform operations for a precise work.

  • Patent number: 10737519
    Abstract: A ribbon cassette includes a case, an ink ribbon, a first spool, a second spool, a rotating member, a clutch spring, and an engaging part. The ink ribbon has one end portion wound over the first spool and another end portion connected to the second spool. The rotating member is engaged with a first inner surface of the first spool. The clutch spring includes a coil like annular part attached to the rotating member, and an extension part extending from the annular part. The engaging part is positioned on a locus of rotation of the extension part. The first spool has a protrusion provided at a second inner surface of the first spool. The case-hole is in communication with an interior of the first spool, and has a portion overlapped with an entire circular region surrounded by a path of rotation of the tip end of the protrusion.

  • Patent number: 9266365
    Abstract: A printer includes a feeding portion, a guide portion, and a processor. The processor determines whether a roll sheet in the printer is an inward facing roll sheet or an outward facing roll sheet. When the roll sheet is the inward facing roll sheet, the processor controls the feeding portion to move the downstream-side end portion of the print medium from the cutting position to an upstream side in the feed direction than the upstream end portion before the printing. And the processor controls the printing portion to start printing. When the roll sheet is the outward facing roll sheet, the processor controls the printing portion to start printing in a state in which a downstream-side end portion of the print medium in the feed direction is positioned further to a downstream side in the feed direction than an upstream-side end portion of the guide portion in the feed direction.

  • Patent number: 9133943
    Abstract: A flow path switching valve has an injection side portion formed with an injection chamber and an outer valve seating surface, and a discharge side portion provided with a partition member formed with an inner valve seating surface. A discharge control block communicating with a discharge chamber is formed with a control flow path which is increased and decreased in volume by a discharge rod. To fill the control flow path with grease, a valve element closes an inner flow path and opens an outer flow path. On the other hand, to discharge the grease in the control flow path to the discharge chamber, the valve element closes the outer flow path and opens the inner flow path. After being supplied to the control flow path, the grease is supplied to the discharge chamber.
