Abstract: PURPOSE:To exhibit blowing performance even under a service condition of large ventilation resistance by providing projection like ribs along the outer periphery to the outer periphery end parts of the blowout side of blades, in an axial blower used for an outdoor machine and the like of a separated type air conditioner. CONSTITUTION:Projection like ribs 2c along the outer periphery ends are provided to the outer perphery end parts of the blowout side of plural number of blades 2b around a hub 2a. Even under an installation condition of large ventilation resistance of an axial blower, air current on the surfaces of blades 2b of an impeller 2 is induced by the projection like ribs 2c provided to the outer periphery end parts in the blowout side, without forced out from the outer periphery end, force form the impeller 2 sufficiently acts on the air current on the blade surface indicated by arrow marks B, therefore blowing performance never falls. Moreover, since a gap toward a blow out port 3b of an orifice 3 is large in the neighborhood of the outer periphery end part of the blowout side, interference between the projection like ribs 2c and the blow out port 3b of the orifice 3 is so little that there are no apprehensions that air current is disturbed by the projection like ribs 2c.

Abstract: PURPOSE:To obtain a cooling device, which will never generate vibration and noise, by a method wherein the cooling device is constituted of a pair of electrodes, in which a fluid pump is arranged in a refrigerant pipeline, a D.C. power source, connected to the pair of electrodes, and a superconductive coil, rotatable around the refrigerant pipeline. CONSTITUTION:Electrodes 12, 13 are connected to a D.C. power source 14 and refrigerant of a fluid pump 9 in a refrigerant pipeline 8a is ionized by the positive and negative electrodes 12, 13 whereby an electric current is conducted from the electrode 12 to the electrode 13. The current is generated between the electrodes 12, 13 in the refrigerant pipeline 8a and strong magnetic field is generated by superconductive coils 10, 11, whereby the flow of refrigerant is generated by Lorentz force. The superconductive coils 10, 11 are rotated around the outer periphery of the refrigerant pipeline 8a to change the positions of the electrodes 12, 13, whereby an angle between the direction of the current and the direction of the strong magnetic field is changed, the Lorentz force is changed and the flow speed of the refrigerant in the pipeline is changed, therefore, a capacity is changed. On the other hand, the superconductive coil is turned more than 180 deg. whereby the direction of the magnetic field is reversed. Accordingly, the Lorentz force is generated in opposite direction whereby the flow of the refrigerant is reversed.

Abstract: PURPOSE:To prevent the vibration and noises in the device by constituting a fluid pump with a super-conductive coil arranged near a coolant piping, a pair of electrodes located in the coolant piping at a position corresponding to the super-conductive coil, and direct current electric power source connected through a switching device which reverses the direction of the electric current. CONSTITUTION:If, for example, a positive electric charge is given to an electrode 13 and negative electric charge to an electrode 14 by means of a switching device 15, the coolant in the coolant piping 9a of a fluid pump 10 is ionized in positive and negative electrodes 13 and 14 and an electric current flows from the electrodes 13 toward the electrode 14. On the other hand between super-conductive coils 11 and 12 a strong magnetic flux is generated from the super-conductive coil 11 toward the super-conductive coil 12 by means of the super- conductive coils 11 and 12. With this magnetic flux a Lorenz force develops by the electric current flowing between the electrodes 13 and 14 and the magnetic flux which flows between the super-conductive coils 11 and 12 and the ionized coolant moves to a heat exchanger 2 on the outdoor side, and a flow of the coolant to the heat exchanger 2 is generated and it circulates in a cooling device. With this arrangement a fluid pump can be formed without mechanical vibration and noises and by reversing the flow of the coolant by reversing the direction of the electric current with the switching device the cooling cycle can be made a room heating cycle.

Abstract: PURPOSE:To make a uniform speed of air passing through a heat exchanger and utilize a maximum capacity of heat exchanging operation in a heat exchanger by a method wherein a fin pitch of the heat exchanger at a part opposing to a blowing port of a blower is constructed to be smaller than that of other portions. CONSTITUTION:Since a width S of a blowing port of a blower 11 is shorter than a length l between end plates of heat exchangers 17 and 17', a distribution of air speed at the front surfaces of the heat exchangers 17 and 17' shows a high value at a part opposing to blowing ports 10 and 10' of the blower, and an air speed at the front surfaces of the heat exchangers at the end portions of the heat exchangers 17 and 17' become low. However, since the fin pitch at the portions 17a and 17a' showing a high air speed at the front surface becomes smaller than that of other portions, an air resistance becomes high and a passing air speed is decreased. Since the fin pitch at the portions where an air speed at the front surface is low is relatively large, the air resistance becomes low and a passing air speed is increased. The passing air speed is made uniform throughout an entire heat exchanger, an efficiency of heat exchanging operation is improved, an air resistance in the entire heat exchanger is reduced, thereby a performance of air blowing can be improved and a noise of air blowing can be reduced.

Abstract: PROBLEM TO BE SOLVED: To attain a feed water control suitable for an automatic ice-making device which feeds water into two ice-trays so as to make ice. SOLUTION: In an automatic ice-making device which supplies water from a water-filled feed water tank 11 to two ice-trays (a first ice-tray 26a, a second ice-tray 26b) provided in an atmosphere below the freezing point through a pump 24 so as to make ice, when feeding water, at first the water is supplied to a specific ice-tray (the first ice-tray 26a), and even in the worst case where a water level of the feed water tank 11 is low and insufficient water is supplied, the amount may be caused to exceed that of the other ice-tray (the second ice-tray 26b) so that the completion of ice-making of the other ice-tray (the second ice-tray 26b) may be recognized upon completion of ice-making of the specific ice-tray (the first ice-tray 26a). Even though two ice-trays are provided, one ice-tray may only be managed, so that its structure is simplified at a low cost. COPYRIGHT: (C)2003,JPO
