A surface treatment apparatus having a treatment bath for immersing and treating a workpiece therein with the workpiece being put into and taken out of said treatment bath by the lifting and lowering thereof and with the workpiece being rotated about a horizontal axial line while in the bath. A jig is provided for holding the workpiece having a pair of suspending points at each end thereof in symmetrical relationship about a horizontal axial line. Ropes suspend the jig with each one connected to...

This invention relates to a surface coating device of bamboos including the stays having anti-corrosion, insect-prevention property and produced by said device characterizing that a nozzle having an opening permitting to freely pass natural materials such as bamboos or tree branches whose outside diameter is irregular is inserted in the resin chamber set up adjacent to the cylinder pushing out melted synthetic resin such as vinyl chloride and by passing said natural materials or the materials wh...

A motor driven agitator providing slow rotational movement of a specimen holder rack with momentary periodic motion in the direction of the rotational axis induces maximum penetration of a treating fluid into specimens held in porous capsules on the rack. A self-aligning, automatic engaging clutch arrangement permits the agitator cover with motor, to be conveniently removed and replaced without complex mechanical components or annoying delays caused by unsuccessful efforts to align separated dri...

An apparatus and a method used to determine the speed and direction of the wind experienced by a wind turbine are provided. The apparatus comprises at least one sensor fixed to the rotor of the wind turbine, an angular sensor to measure the angular position of the rotor of the wind turbine, and a circuit which converts the relationship between the output of the at least one sensor and the output of the angular sensor into the speed and direction of the wind experienced by the wind turbine. Accor...

A wind turbine for converting wind energy to useable energy having a plurality of overlapping sail members. The sail members extend radially outward from a vertically disposed shaft in three columns positioned equidistantly around the shaft. The overlapping sail members hang downwardly in a naturally biased, vertical orientation so as to block rotational movement of each other in one direction. This configuration allows the wind to engage with the sail members on one side of the shaft to rotate ...

An apparatus for heat treating semiconductor wafers is disclosed. The apparatus includes a heating device which contains an assembly linear lamps for emitting light energy onto a wafer. The linear lamps can be placed in various configurations. In accordance with the present invention, tuning devices which are used to adjust the overall irradiance distribution of the light energy sources are included in the heating device. The tuning devices can be, for instance, are lamps or lasers.

Aspects of the invention related to a system for providing advance notice of impending contact between a stationary component and a rotating component in a turbine engine. For example, the system can be used to warn of potential contact between a seal holder and a rotor disk in the compressor section of the engine. In one embodiment, a pad or other component can be provided on the stationary seal holder. If the seal holder and the rotor disk approach each other during operation, the pad can cont...

A journaled rotor is provided for rotation about an axis to be disposed transverse to a fluid flow path and the rotor includes a plurality of mounting portions spaced radially outwardly from and circumferentially about the axis having a plurality of vane assemblies rotatably mounted therefrom for angular displacement about axis generally paralleling the axis of rotation of the rotor. Vane assembly displacement control structure is operatively connected to the vane assemblies for angularly displa...

The present invention provides a new and improved method for quickly and accurately determining the rotor blade angle of a wind power installation. The present invention also allows for the rotor blade angle measurements to be taken from the ground, thereby allowing the measuring equipment to be easily disconnected and transported to other sites. For example, a rotor blade angle of a wind power installation may be determined by using a spacing measuring device to measure the spacing between the ...

The present invention provides a heat transfer assembly that, when coupled to an object, is capable of keeping the object at a uniform elevated temperature while removing large amounts of heat from an external source. The assembly may be contained in a pedestal for use in a UV-cure chamber. The heat transfer assembly includes a heating element to control the wafer temperature and a cooling element to remove incident IR heat from the wafer and pedestal. A heat resistant layer having a calibrated ...
