  • Patent number: 11386373
    Abstract: Provided is a work management device for arranging a worker in consideration of a change of work efficiency. In a work management device 10, an index acquisition unit 11 acquires, for each work section, a work evaluation index calculated based on work history performed by a worker. A duration time acquisition unit 12 acquires a duration time for which a work status of the worker is the work evaluation index. A cost acquisition unit 13 acquires a cost incurred when the worker moves between the work sections. A determination unit 14 acquires an estimated work amount performed by the worker until the duration time is elapsed. The determination unit 14 determines, based on the estimated work amount and cost, arrangement of the workers in the plurality of work sections in such a way as to increase work efficiency in a whole of a work range.

  • Patent number: 6666390
    Abstract: Reduced thickness portions in a form of a recess are formed in a contact surface in a lower end of a tip packing, which contacts with an upper end of a nozzle body. Furthermore, reduced thickness portions in a form of a recess are formed in a contact surface in an upper end of the tip packing, which contacts with a nozzle holder. With this arrangement, a sealing surface pressure around a connection between corresponding fuel passages is increased with use of a reduced axial fastening force by reducing the sealing surface area in each contact surface. Furthermore, one of the reduced thickness portions formed in the contact surface in the upper end of the tip packing is used as a leakage recovery passage.
