摘要： A blower includes: an impeller on which there are arranged axial flow blades 40 mounted at circumferential intervals to an outer peripheral surface of a boss; a case surrounding the impeller; and a bell mouth cylindrically constricted to guide gas into the case, wherein an inner diameter of the bell mouth is smaller than an outer diameter of the impeller. Further, each blade has, in the radial direction, a sweepforward wing portion situated on the boss side and exhibiting a positive advance ratio value, and a sweepback wing potion situated on the outer peripheral side of the blade and exhibiting a negative advance ratio value, with the arc length of each blade increasing from the boss side toward the outer peripheral side. Therefore, it is possible to achieve an improvement in ventilation efficiently, through an increase in static pressure and to achieve a reduction in noise.

摘要： A sound absorbing mechanism using a porous material has a sound absorbing plate of a thin plate porous material made by partially heating for welding plastic particles and a supporting member for supporting the sound absorbing plate and forming a back air space. More than one pair of resonators having a separated back air space in the aforementioned back air space are fixed to the sound absorbing plate, and the resonators are disposed to be opposed to a sound insulator with the supporting member between. Plural reflecting members or increased sound absorbers may be disposed to be opposed to the surface of the sound absorbing plate opposite to the surface equipped with the resonators, or a perforated protecting plate fixing the plural reflecting members or the increased sound absorbers thereon are may be equipped. The sound absorbing mechanism has a superior sound absorption characteristic from lower frequencies to higher frequencies.

摘要： An air conditioner includes bent portions provided at edge portions of a plurality of fins juxtaposed on a heat exchanger, respectively. Each bent portion is located at an edge portion which is near a cross flow fan and on the sides of said fin facing the cross flow fan and lying generally between the cross flow fan and a coolant pipe of the heat exchanger. The bent portions are formed by bending the edge portions so as to be in parallel to the coolant pipe and staggered along an axis parallel to the coolant pipe. Thereby, the noise during the operation of the cross flow of the air conditioner can be reduced.

摘要： In an apparatus for displaying a flying object, an air flow is created in a duct by a group of blowers. A holding line is attached to a lightweight flying object, and movement of the lightweight flying object is restricted by the holding line. By making the lightweight flying object fly in the air flow, the lightweight flying object is able to fly even in a small space.

摘要： A blowing apparatus includes a suction passage having a suction chamber enclosed by rigid body surfaces, suction ports opening toward the suction chamber for sucking air from outside, and a fan suction port serving as a suction port for a blower, the suction ports, the suction chamber, and the fan suction port being arranged in nonlinear form. In such blowing apparatus, a doughnut-like straightening guide is arranged on an opening edge on the suction chamber side of the fan suction port. The straightening guide has a projection toward the suction chamber, an appropriate thickness in the radial direction, and a guide passage matching the fan suction port in the middle thereof.
