Abstract: PURPOSE:To reduce traffic noise by forming a sound absorbing board of continuous bubble hard foaming material in a convex curved surface, and providing soundproof cylinders in the width direction so that both ends thereof are fitted to a noise insulating board, and by arranging the soundproof cylinders at prescribed intervals so as to direct toward the noise source. CONSTITUTION:A soundproof wall 1 is formed by curvedly bending a sound absorbing board 2a of foaming aluminum or the like which contains a large number of bubbles communicating with each other, and the width-directional both ends thereof are fixed to both ends of a noise insulating board 2b of aluminum flat plate to form a soundproof cylinder 2 of a half-blade shape in section. Then, the soundproof cylinders 2 are adjacently brought into contact with each other directing the convex cured surface sides of the sound absorbing boards 2a of respective soundproof cylinders 2 toward the noise source side, or are arranged at prescribed intervals. And the section of the empty space 3 perpendicular to the longitudinal direction of the soundproof cylinder 2 is made in a semicircular shape, and the sound waves from the noise source are incident on the sound absorbing board 2a so that they are penetrated into the empty space 3 through the communicating bubbles in the sound absorbing board 2a. Thus, the sound waves of a wide range of frequencies can be absorbed.

Abstract: PURPOSE:To increase splash effect affecting the cooling capacity and remove unnecessary splash upon the heating operation of a heat pump by a method wherein a separate nozzle for an outdoor fan is provided between the fan and the outdoor side heat exchanger while the splash of the condensed water utilizing wind pressure due to the nozzle thereof is effected. CONSTITUTION:The indoor side and the outdoor side are separated by a partition plate (j) and the inside is cooled and defumidified with the indoor side heat exchanger (b) and the condensed water is collected to a dew-pan (b) upon cooling operation. Upon heat pump heating, the outdoor side exchanger (f) becomes an evaporator to collect the heat at the outdoor side, in this case, an outdoor side base (k) is constituted so as to collect the condensed water. The condensed water collected to the dew-pan (b) is sent to the nozzle (g) through a tube (h) upon cooling operation. The condensed water at the nozzle (g) is slided on the nozzle inside surface by the wind pressure of the outdoor side fan (e), thereafter, it is splashed by the outdoor side heat exchanger (f). The condensed water collected into the outdoor side base (k) without evaporating may be discharged out of the optional draining port (i) same as the condensed water treatment upon the heating.

Title: Nozzle for vacuum cleaner
Inventor: ISE SHINSUKE
IPC: A47L9/02
Filed: 1991-02-18
Abstract: PURPOSE:To efficiently clean both the floor surfaces of a carpet and a mat or a bare board floor by installing a auction pipe so as to be freely rotatable to a nozzle main body in which plural lines of suction bodies whose cross section is a ship shape, formed by a soft material, are arranged on the bottom face of a nozzle. CONSTITUTION:As for the carpet floor surface, especially, the carpet floor whose hair foot is long, a suction body 11 is moved in a longitudinal direction. Accordingly, the tip part of the suction body 11 pushes aside the hair feet and moves, thus resistance by the hair feet is small and cleaning is executed easily. On the other hand, as for a bare board floor and a mat floor, a nozzle 10 is moved in the side direction of the suction body 11. In this case, since the width of the nozzle 10 is wide and the arrangement of the suction body 11 also has no dead angle, the efficiency of cleaning is improved. Also, since the auction body 11 is formed by a soft material, the suction body 11 does not damage the floor surfaces of the mat and the board.
