摘要:
An object is to provide a wind turbine blade having a serrated plate that can be formed irrespective of the overall structure of the blade, that is attached in the optimum shape, and that can effectively suppress noise occurring at a trailing edge thereof, and also to provide a wind power generator using such a wind turbine blade. Provided is a wind turbine blade (9) formed by bonding a back skin (19) and a front skin (21) and having a serrated plate (35) attached to a trailing edge (33) thereof, and the serrated plate (35) is formed so as to be attached by bonding the back skin (19) and the front skin (21).

Provided are a wind turbine blade that can reduce the thickness of a turbulent-flow boundary layer generated on the blade surface of a blade tip portion to prevent noise generated at a trailing edge portion effectively, as well as a wind power generator using the same. Provided is a wind turbine blade, which is a wind turbine blade having an airfoil shape in cross section, wherein an angle-of-attack decreasing portion that decreases an angle of attack during rotation at at least a predetermined rotational speed is provided over a predetermined range from a blade tip to a blade root side.

A multilayer glass structure constructed by joining the edge portions of a plurality of glass sheets by a sealant through spacers having an adsorbent filled therein. According to this invention, the adsorbent comprises a combination of a granular zeolite composed of a core of a synthetic zeolite/clay binder mixture containing the synthetic zeolite in an amount larger than its average content in the granular zeolite and a shell of a synthetic zeolite/clay binder mixture containing the clay in an amount larger than its average content in the granular zeolite, with granular activated carbon having on its surface 1 to 20% by weight, based on the activated carbon, of a coating of a synthetic resin latex. The adsorbent can effectively adsorb water vapor and the vapor of an organic solvent evaporated from the sealant, and prevent dew deposition on the glass surface. Moreover, it does not yield dust even when the glass structure is handled under severe conditions.

A process for producing activated fibrous carbon comprises carbonizing and activating vegetable fibers in the presence of at least a member selected from the group consisting of ammonium salts of inorganic acids, nitric acid and boric acid and zinc chloride of about 5 to 80 parts by weight per 100 parts by weight of the vegetable fibers. The process increases remarkably a yield of activated fibrous carbon and therefore permits the supply of activated fibrous carbon at by far reduced costs as compared with the conventional process, and the resulting activated carbon shows superior adsorption capability and flexibility.

An alarm device for signalling a reduction of pneumatic vehicle tire pressure comprises an oscillator 6 having an oscillation coil secured to a chassis of a vehicle; and a resonator 1 secured to the peripheral portion of a wheel having a tire adjacent to the oscillation coil and consisting of a pressure switch 4 for sensing an abnormal tire pressure change and a resonance coil and a capacitor 5 tuned to an electromagnetic wave radiated from the oscillation coil. A signal processing device contains a means for sensing a change in an oscillation condition generated in the oscillator due to a resonant condition of the resonator switched on and off in accordance with abnormal internal tire pressure and for processing a signal from the sensing means; and an alarm for generating a warning signal in accordance with the output of the signal processing device. The latter comprises a signal input section 21 having a desired number of input terminals, a signal processing section 22 having an arithmetic circuit connected to the signal input section, a resettable latch circuit 30,32, and an alarm section 23 operated by the output of the latch circuit whereby an alarm signal is not generated at normal internal pressure and during stops of the vehicle.
