摘要： PURPOSE:To prevent a funnel from becoming large in size and to attain improvement in a pumping capacity and suppression of noise by a construction wherein a sharply tapered part is provided at the lower end part of a funnel and a water surface is positioned at the sharply tapered part, while a straight tube part is provided in a continuity to the lower end of the sharply tapered part. CONSTITUTION:A funnel 4 is constructed of a gently tapered tubular body 4a shaped like an inverse truncated cone, a sharply tapered tubular body 4b shaped like an inverse truncated cone and provided in a continuity to the lower end part of the tubular body 4a and further a straight tube part 4c provided in continuity to the lower end of the tubular body 4b. A sirocco fan 5 is disposed above the funnel 4 and the funnel 4 is connected to the lower end of a shaft l of the fan so that it rotates horizontally with the fan 5. The lower part of the funnel 4 is immersed in water so that the surface of the water is positioned at the sharply tapered part 4b. According to this constitution, the water in contact with the inner and outer surfaces of the funnel 4 rotates with the rotation of the funnel 4 so that it follows this rotation, rises along the inner surface of the funnel 4 by a centrifugal force and then scatters around from the upper edge of the funnel.

摘要： PURPOSE:To prevent generation of discomfort sound and a variation in a pumping amount by a simple structure by standing a cylindrical metal gauze concentrically with a funnel from a bottom of a water pan at inside or/and outside of an end of the funnel. CONSTITUTION:A condenser body 1 having a top late 1a and a cylindrical skirt 1b is arranged above a water pan 2. a cylindrical stainless steel gauze 7 is so stood to protrude at its upper end from a horizontal surface as to surround a lower part of a funnel 4 at a center of the pan 2. The funnel 4 is mounted at a shaft of a fan motor 11 and rotatably driven together with a fan 5. Accordingly, water in the pan 2 tends to form a vortex flow due to recessing at a center by a centrifugal force, but the gauze 7 becomes a resistance for the vortex flow to suppress generation of the vortex flow, thereby preventing generation of noise due to the vortex flow and further suppressing a variation in a water level near the center of the pan 2 by the vortex flow, and hence a variation in a pumping amount can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a pipe fitting convenient to use whereby the hose drawout direction can be changed any as desired while the fitting remains in one sort. SOLUTION: A pipe fitting is composed of a socket 1 and a plug and can generate connection by instant coupling motion with possibility of being mounted and removed freely. A hose end 2 for connection of a hose is provided at the base of at least either of the socket 1 and plug rotatably so that the heading of the hose end 2 about the axial direction is changeable with respect to the axial direction of the socket 1 and/or plug.

摘要： PROBLEM TO BE SOLVED: To supply grease sufficiently over the whole section between an inner peripheral face of a cock storage hole and an outer peripheral face of a cock to prevent running out of grease. SOLUTION: Width W1 of a rising face 15 is set to a smaller value than the inside diameter of a gas passage 12 and a gas hole 21. The rising face 15 is arranged in such a manner that the whole section in the direction along an axis of a cock 2 enters each opening of the gas passage 12 and the gas hole 21.

摘要： PURPOSE:To incorporate a water droplet capturing capacity equivalent to a metal gauze or more and to reduce a ventilating resistance as compared with the gauze by forming a plurality of protrusions at a funnel from an upper edge upward, and supporting an annular shielding plate to upper ends of the protrusions. CONSTITUTION:A funnel 4 scatters water scraped from a water pan 2 on a condensing coil 3 by a centrifugal force. Water scraped by a water scraping vane 9 at a lower end of an inverted truncated conical funnel body 4 and raised along an inner wall is radially scattered from an upper edge of the funnel 4. An annular shielding plate 8 so disposed as to cover the upper edge of the funnel 4 captures the water droplets or alters its direction to eliminate directing upward of the droplets. A plurality of protrusions 7 formed at an equal interval at the upper edge of the funnel 4 support the plate 8. The water scattered from the upper edge of the funnel 4 to its periphery forms a continuous film, thereby preventing disturbing of a rising air flow.

摘要： PURPOSE:To control an air conditioner by providing first, second, and third lines between a heat source apparatus and each of terminal apparatuses, a change-over switch at each terminal apparatus, and a means of controlling the supply of heat medium which is placed at the heat source apparatus and acts in response to the output of detective means. CONSTITUTION:To a single heat source apparatus 1 terminal apparatuses 2a-2c are connected by means of first lines L1a-L1c, second lines L2a-L2c, and third lines L3a-L3c. At each of the terminal apparatuses 2a-2c a change-over switch 3 is provided with a common contact 4 connected to the first line L1a, individual contacts 5, 6 connected respectively to the second lines L2 and the third lines L3. To detect the temperature of the rooms, temperature detecting elements 7 are provided, and to set the target temperature, temperature-setting devices 8 are provided and their outputs are fed to processing circuits 9. To these processing circuits 9 signals from the contacts 4, 5, 6 are also fed. The processing circuits 9 periodically turn on and off switching elements provided respectively in the lines L1.
