  • Publication number: 20090278361
    Abstract: When a rotation frequency of a rotary shaft 2 is not more than a predetermined value, a clutch 7 connects the gearing systems 6 and 8 with each other. Then, the rotation from the rotary shaft 2 is accelerated through the gearing system 6, clutch 7, and gearing system 8, and is transmitted to the rotary shaft 4. At this point, a freewheel clutch 5 disconnects the rotary shafts 2 and 4 from each other. On the other hand, when the rotation frequency of the rotary shaft 2 surpasses the predetermined value, the clutch 7 disconnects the gearing systems 6 and 8 from each other. Then, the rotation frequency of the rotary shaft 4 drops. When the rotation frequency of the rotary shaft 2 equals that of the rotary shaft 4, the freewheel clutch 5 connects the rotary shafts 2 and 4 with each other, thereby transmitting the rotation from the rotary shaft 2 as it is to the rotary shaft 4 via the freewheel clutch 5.

  • Publication number: 20080191484
    Abstract: Wind power can be always detected even when a wind turbine 11 forcibly brakes, as well as cost of components can be reduced. A generator includes a wind turbine 11 rotated by wind power to generate a driving force, a dynamo 19 operated by the driving force of the wind turbine 11 to generate electricity, a short-circuit brake 21 for switching the output side of the dynamo 19 between an output state and a short-circuit state, a rotational speed input unit 41 or an arithmetic processing part 51 for recognizing the magnitude of the wind power in both of the output and short-circuit states based on the rotational speeds of the wind turbine 11 in both of the output and short-circuit states, and an arithmetic processing part 51 for determining which state the dynamo 19 should be changed over to between the output and short-circuit states based on the rotational speed of the wind turbine 11 and controlling the switching of the short-circuit brake 21 based on the determination result.

  • Patent number: 6770109
    Abstract: A substrate transport container having a carrier box including a container body and a door hermetically sealably covering an opening provided in the front of the container body. Partitions form a circulating flow path in the carrier box. The circulating flow path has a flow path in which air flows toward substrates and a flow path in which air flows toward a fan. A substrate carrying section is disposed in the flow path in which air flows toward the substrates to carry the substrates in such a way that the principal surfaces of the substrates are approximately parallel to the flow path in which air flows toward the substrates. A particle removing filter and a gaseous impurity trapping filter are placed on the upstream side of the substrate carrying section in the flow path in which air flows toward the substrates. A fan motor for driving the fan is incorporated in the carrier box to form an air current for circulating through the circulating flow path.
