A current detection circuit included in a power supply detects a current flowing to an inductance element from a detection tap of an inductance element connected between an output terminal and an output of a first switching element. A control circuit included in the power supply controls a first control terminal of the first switching element and a second control terminal of a second switching element and calculates an output current flowing to a load based on the current detected by the current detection circuit.

Power supply and control method for power supply

A coating agent includes a polyurethane and a hydrocarbon-based synthetic wax.

Coating agent

To provide an inorganic fiber that suppresses adverse effects on a human body and living environments, exhibits high biosolubility, and also exhibits excellent heat resistance as a constituent material for a filter material, a sealing material, or the like. The inorganic fiber comprises 30 mass % or more and less than 81 mass % of AlO, more than 19 mass % and 65 mass % or less of MgO and 0 mass % to 40 mass % of SiO, wherein the total content of AlO, MgO and SiOrelative to the entire fiber is 98 mass % or more.

Inorganic fiber and method for manufacturing the same

Provided are inorganic fibers which can exhibit high biosolubility and have excellent heat resistance as the constituting material for a filter material, a sealing material or the like, while exerting minimized effects on the human body or the living environment even when the fibers have an average diameter of 1 &#x3bc;m or less. Inorganic fibers including 35 mass% to 88 mass% of AlO, 3 mass% to 45 mass% of CaO and 5 mass% to 40 mass% of SiO, wherein the total content of AlO, CaO and SiOis 98 mass% or more of the entire fibers.
