Abstract:
The air-conditioning system sends, to a living room, air-conditioning room air in an air-conditioning room independent of the living room. In the air-conditioning room, an air conditioner is installed. A refrigerant concentration sensor detects a concentration of a refrigerant contained in the air-conditioning room air. A state changer switches between a first state where the air-conditioning room air is sent to the living room and a second state where air coming in and out of the air-conditioning room is less than the air-conditioning room air in the first state. A leakage determination unit determines whether or not the refrigerant is leaking by acquiring the refrigerant concentration detected by the refrigerant concentration sensor in the second state.
Abstract:
Provided is a heat-dissipating resin composition including: a rubber material having an average emissivity of 80% or higher in a wavelength range from 5 μm to 20 μm; and a filler having a grain diameter of 15 μm or smaller and an aspect ratio of 3 to 10, wherein the heat-dissipating resin composition has an emissivity of 90% or higher in the wavelength range from 5 μm to 20 μm.
Abstract:
Electrolytic manganese dioxide for lithium primary batteries has a sodium content of 0.05 to 0.2% by mass, and a pH of 5 to 7 as measured according to JIS-K-1467. Using this electrolytic manganese dioxide as a positive electrode active material for lithium primary batteries enables the batteries to be excellent in both initial discharge characteristics and long-term discharge characteristics.
