A vertical axis type wind power station and a blade manufacturing process, which can stabilize the turning motions of blades and can raise the power generation efficiency by lightening the blades to smoothen the turning motions of the blades; a structure and method for mounting the wind-driven device of a wind power station, by which the wind-driven device can be easily disposed at the upper portion of a building; and a windbreak wind power plant for breaking the wind by using the vertical axis type wind power stations or wind-driven devices arranged along the shoreline or the like.

Vertical axis type wind power station

An object of the present invention is to provide a linear actuator in which reliability is improved, and performance is also easily improved. The present invention provides a linear actuator including a stator, a movable element having an iron member, and being reciprocatable with respect to the stator, a permanent magnet fixed to the stator so as to be opposed to the iron member, and a coil fixed to the stator. Because both the coil and the permanent magnet are fixed to the stator, electrical current does not have to be supplied to the movable element, and the feeder lines connected to the coil will not be broken due to the movement of the movable element. In addition, the weight of the movable element will not be increased even when the weigh of the permanent magnet is increased in order to obtain high magnetic flux density for improvement in performance. Moreover, because the movable element does not include a magnet, a magnetizing operation does not have to be applied to the movable element. The permanent magnets may be a pair in which the directions the magnetic poles thereof differ from each other, and two pairs of permanent magnets may be provided. The number of magnetic fluxes that run through the magnetic pole elements and the iron member can be increased by providing a magnetic reluctance section around the permanent magnets.

Linear actuator

The wafer mapping system has an access port for transferring a wafer in and out and detects an accommodated wafer for a cassette in which slots for accommodating and holding inserted wafers are disposed in tiers. The wafer mapping system includes (1) a receiver that is fixed to a member facing the access port for receiving elements arranged serially along a height direction of the cassette, and (2) a transmitter that is disposed movable in an up and down direction of the cassette and transmits a signal toward a wafer accommodated in each of the slots of the cassette. The receiver receives a signal from the transmitter, and thereby the presence or absence of a wafer and a state of a wafer accommodated in each of the slots of the cassette are detected. Thereby, with a simple system configuration, an accommodation state of the wafer can be accurately detected.
