  • Patent number: 11387472
    Abstract: The present disclosure provides an energy management system capable of improving energy efficiency. The energy management system includes: a fuel cell configured to supply energy used in a facility; a first hydrogen supply unit configured to supply hydrogen to the fuel cell by causing a power generation apparatus that uses renewable energy to perform water electrolysis; a second hydrogen supply unit configured to supply hydrogen to the fuel cell by reforming natural gas supplied via a pipeline; and a control unit configured to determine a ratio between hydrogen supplied from the first hydrogen supply unit to the fuel cell and hydrogen supplied from the second hydrogen supply unit to the fuel cell. The control unit determines the ratio in accordance with a percentage of heat energy and energy other than the heat energy with respect to the energy used in the facility.

  • Patent number: 6766894
    Abstract: A movable body movable on a given path is provided with a support section for an object to be carried. Supports for supporting an object to be carried are disposed in the lower portion of the support section on the right and left sides thereof such that a support position can be changed. The given path is provided with a changer positioned between the right and left supports for changing the support position provided by the supports. The movable body is moved until it is stopped with the now-empty support section opposite the changer. The changer is then actuated, thereby changing the support position provided by the supports. Thus, different kinds of objects to be carried can each be stably supported. The common changer simplifies the configuration and operation and enables the support position provided by the right and left supports to be changed quickly and reliably.

  • Publication number: 20030000413
    Abstract: A movable body (9) movable on a given path (4) is provided with a support section (30) for an object to be carried. Supports (50) for supporting, from below, an object to be carried are disposed in the lower portion of the support section (30) on the right and left sides thereof such that a support position can be changed. The given path (4) is provided with a changing means (70) positioned between the right and left supports (50) for changing the support position provided by the supports (50). The movable body (9) is moved until it is stopped with the support section (30), which is now empty, opposed to the changing means (70), whereupon the latter is actuated, whereby the support position provided by the supports (50) can be changed. Thus, a plurality of kinds of objects to be carried can each be stably supported. The common changing means (70) simplifies the configuration and operation and enables the support position provided by the right and left supports (50) to be changed quickly and reliably.
