摘要:
A method of diagnosing the deterioration of a zinc oxide type lighting arrester having one or more series-connected non-linear resistance elements including steps of elimination of the effects of capacitive currents from phase currents; obtaining a synthesized waveform using a window type transformer based on the resistance elements alone; and diagnosing the presence of a deteriorated non-linear resistance element by generating a first pulse voltage when the maximum crest value of the synthesized waveforms exceeds a predetermined value, generating a second pulse voltage representative of terminal voltage of the resistance element, and calculating the difference between the first and second pulse voltages.
摘要:
To provide a method and apparatus for treating a waste gas containing fluorine-containing compounds, according to which PFCs can be decomposed efficiently even at low temperature, and moreover fluorine from the product of the decomposition can be recovered for reuse efficiently. An embodiment of the present invention relates to a method of treating a gas containing a fluorine-containing compound, comprising contacting the gas with a treatment agent comprising a mixture of aluminum hydroxide and calcium hydroxide. Moreover, another embodiment of the present invention relates to an apparatus for treating a gas containing a fluorine-containing compound, comprising a treatment column comprising a hollow interior that is packed with a treatment agent comprising a mixture of aluminum hydroxide and calcium hydroxide and through which the gas can pass, heating means capable of heating the hollow interior to a prescribed temperature, a gas introduction port for introducing the gas to be treated into the hollow interior, and an exhaust pipe for discharging gas produced from the hollow interior.
摘要:
A mark is displayed to a manually scrapped component capable of being disassembled manually without disassembling or crushing by machine at the time of discard or recovery of an electric appliance after use, and the manually scrapped component is manually scrapped from a product, and in the case of crushing by machine thereafter, the mark display is a mark capable of separation into plural kinds of substance on which a cost burden is imposed and valuable substance after recovery, and scrapping can be performed easily at low cost.
摘要:
A refrigerating cycle apparatus including an inverter driven compressor with controllable speed of rotation, a four-way valve, an indoor heat exchanger, a pressure reducing device, outdoor heat exchanger, a defrosting condition detector for detecting a frosting state of the outdoor heat exchanger in a heating operation, a defrosting operation controller for carrying out a defrosting operation based on a detection signal from the defrosting condition detector and having a minimum operable frequency controller for controlling a minimum operable frequency for the compressor on restarting after completion of the defrosting operation and/or a starting speed controller for controlling a starting speed for the compressor based on a detection signal from the defrosting condition detector on restarting after completion of the defrosting operation in order to provide proper lubrication after a defrost operation.
摘要:
An information input device is provided which is to make input of information by operating a disk-shaped rotating member. The device includes the rotating member (36) which is rotatable with one main side thereof being operated, rotation detecting means (23, 32) for detecting a rotation of the rotating member (36), a central switch activator (26) provided at the center of rotation of the rotating member (36), a central switch (270) which is activated by operating the central switch activator (26), and a plurality of peripheral switches (27) which are turned on when a portion, apart from the center of rotation, of the rotating member (36) is pressed. Rotating the rotating member and pressing the apart portion makes input of information, and operating the central switch activator sets the information thus entered.
