Abstract: PURPOSE:To positively prevent the arching and the accumulation of the tea-leaves, and in addition, to contrive the simplification of the mechanism concerned by providing a hopper shaft, a vibration plate inserted being made freely rotatable with the hopper shaft working as the pivot of the rotation, and a worm-shaped auger which conveys tea-leaves by the motion of its twisting, all of the above-mentioned parts being housed in the tea leaves feed hopper. CONSTITUTION:By bringing in contact the periphery of the top-end part 27 of the screw-thread of an auger 24 and one end of vibration plate 14, where the auger 24 rotates, following said rotation, the end of the vibration plate 14 is pushed upward caused by the rubbing action against the rotating screw in the manner of rubbing on the periphery of the top-end 27 of the screw thread. Because of this action, the tea-leaves stored in the feed-hopper is subjected to stirring in the form of being pushed up once. As the rotation of the auger proceeds and reaches a certain point where the vibration plate 14 separates from the engagement and rubbing state does not exist with the periphery of the top-end 27 of the screw thread, tea-leaves covering the distance of approximately one pitch which is equal to a distance between two adjacent screw-threads, that is the distance to the top-end 27 of this side which follows being twisted, fall under the weight of tea-leaves. At this time, the shock of the falling tea-leaves weight applies on the vibration plate 14, resulting in that the tea-leaves which have been pushed up in the feed hopper so far are prevented from causing arching and accumulating because their falling shock are applied thereon.

Abstract: PROBLEM TO BE SOLVED: To improve intake efficiency of refrigerant into a cylinder block and improve muffling effect of an intake muffler by composing the intake muffler of a conical front cone and an inverted conical rear cone. SOLUTION: A reed valve 15 repeats opening-closing action several times at the time of an intake stroke so as to generate pressure wave near an intake hole 14. This pressure wave travels as sound wave toward a muffler inlet part, and is amplified by the conical taper of a front cone 18 and reflected toward a muffler outlet part by the inverted conical taper of a rear cone 19. The reflected pressure wave reaches the muffler outlet so as to accelerate intake of refrigerant into a cylinder block, which results in improving intake efficiency. Since most of pressure wave is reflected by the rear cone 19, sound wave radiated from the muffler inlet part can be reduced so as to improve muffling effect.

Abstract: PROBLEM TO BE SOLVED: To prevent wear of a rotative speed variable compressor of a refrigerator caused by a shortage of lubricating oil due to an increase in viscosity of the lubricating oil and enhance the reliability, by stopping a machine room fan when the compressor operates at low speeds and the outside temperature is low. SOLUTION: A temperature controller 4 decides and outputs rotative speed signals of a compressor 6 and an outside temperature detector 13 outputs outside temperature signals. When a machine room fan rotative speed controller 7 judges the rotative speed of the compressor 6 to be lower than the normal rotative speed and the outdoor temperature to be lower than the specified temperature from the rotative speed signals and the outside temperature signals, a machine room fan 9 is stopped to prevent wear of sliding part of the compressor 6 by averting an excessive drop in temperature of the compressor 6 that causes a shortage of lubricating oil because of an increase in viscosity of the lubricating oil.

Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of defrosting, save energy, and to contrive freshness of a food at a high value by a method wherein defrosting is executed by operating a compressor through superlow rotation. SOLUTION: When the operation time of a number of revolution variable type (capacity variable type) compressor 17 attains a specified time by a defrosting timer 11, the number of revolutions variable type (capacity variable type) compressor 17 is operated at low rotation and cold air feed means 10 is stopped. When the number of revolutions variable type (capacity variable type) compressor 17 is operated at low rotation, the vaporization temperature of a refrigerant is increased to at least 0 deg.C being temperature at which frost is molten, and the temperature of a vaporizer 3 becomes also at last 0 deg.C. Frost adhered to the vaporizer 3 is defrosted through direct heat-exchange with the vaporizer 3 the temperature of which is at least 0 deg.C. This constitution improves the efficiency of defrosting, saves energy, and maintains freshness of a food at a high value.
