Abstract: A wind power generator is enclosed at the center of a duct. The duct comprises an upper and lower duct panels having solar panel. The distance between the upper and lower duct panels is the smallest at the center where the wind power generator is mounted. The distance gradually increases as the upper and lower duct panels extend further away from the wind power generator. Thus, the duct collects wind blowing toward the wind power generator and increases the speed of the collected wind, thereby achieving an increase in the quantity of power generated in the wind power generator.

Abstract: A household power supply system using an electric vehicle, comprises an external power system, a house with an indoor power line, an electric vehicle having a vehicle power system with vehicle batteries, a charger/discharger for connecting separably the indoor power line and the vehicle power system, and a controler for controlling power supply to the indoor power line. The power supply system is capable of supplying energy from the household power supply to the vehicle batteries at the normal state, and conversely supplying energy from the vehicle batteries to the indoor power line at the time of emergency, etc. to enable employment of indoor electric equipments.

Abstract: An FIP (Formed In Place) gasket arrangement includes three hollow parts which are joined with each other in such a way as to sealingly separate the inside and outside thereof. Two of the parts have surfaces which are flush with each other and adjoin at a line extending between the inside and outside of the two parts. The remaining one of the parts has a surface joined with the surfaces of the two parts by interposing therebetween an FIP gasket. The two parts also have edges extending along the above mentioned line, one of the edges being partially chamferred to provide a chamber. The FIP gasket has a portion filling the chamber.
