Abstract: Wind power turbines are largely divided into vertical axis type wind power turbines and propeller type (horizontal axis type) wind power turbines. The present invention discloses a vertical axis type wind power turbine. The airfoil of blades in this vertical axis type wind power turbine is formed in such manner that, denoting a proper position on the airfoil chord line as a camber reversing position, a camber having a downward convex curvature is given between said position and a leading edge and a camber having an upward convex curvature is given between said position and a trailing edge so as to be a mean line and a rational thickness distribution is given to this mean line. This vertical axis type wind power turbine is formed by keeping the spanwise direction of the above mentioned blade parallel with a vertical rotary axis and fitting a plurality of blades at regular intervals at a distance to the vertical rotary axis through respective supporting arms.

Abstract: A hydrophilic separating carrier is a porous spherical gel having primary hydroxyl groups and is produced by an aqueous suspension homopolymerization of pentaerythritol dimethacrylate or an aqueous suspension copolymerization of pentaerythritol dimethacrylate and a methacrylate monomer having hydrophilic group and/or hydrophilic convertible group.

Abstract: Wind turbines are largely divided into vertical axis wind turbines and propeller (horizontal axis) wind turbines. The present invention discloses a vertical axis high speed wind turbine provided with a starting and braking control system. This vertical axis wind turbine is formed by having blades of a proper airfoil fitted to respective supporting arms provided radially from a vertical rotary axis by keeping the blade span-wise direction in parallel with said axis and being provided with a low speed control windmill in which the radial position of each operating piece varies with a centrifugal force produced by the rotation of said vertical rotary axis.

Abstract: A composite material of a ferrous cladding material and an aluminum cast matrix which composite material exhibits excellent performance and a method for producing the same which can be carried out quite easily. The composite material comprises a ferrous cladding material, powder particles bonded to the ferrous cladding material, seizing portions defined by the powder particles, and a cast matrix of aluminum or its alloy held by the seizing portions. The method comprises the steps of spreading powder particles over a ferrous cladding material, bonding the powder particles to the ferrous cladding material by sintering, and casting aluminum or its alloy over the sintered surface. Further, a metallic layer can be formed between the bonded powder particles and the cast aluminum, by plating.

Abstract: Disclosed is a continuous atmosphere controlled furnace for aluminum brazing and other purposes. A plurality of pots are suspended from a circular roof rotatable in a horizontal plane and arranged in a circle having a center on the axis of rotation of the roof. Each pot comprises a body having an open top and a cover capable of closing the open top of the body. The open top of each pot projects above the roof and that portion of each pot which contains the material to be heated extends downwardly below the roof. The material to be heated is supported on a hanger depending from the cover of each pot and the cover is lowered to place the material in the pot and close the pot. The furnace further includes an atmosphere gas distributor having its center on the axis of rotation of the roof and connected to the pots by gas supply and exhaust ducts. A method of supplying atmosphere gas through the pots is also described.
