Abstract: An electric leakage detection apparatus may quickly detect an electric leakage. An electric leakage detection apparatus includes a pulse generator that supplies a pulse to a coupling capacitor, a voltage detector that detects a voltage at the coupling capacitor, an electric leakage determination unit that compares the voltage detected by the voltage detector to a first threshold and determines presence or absence of the electric leakage of a DC power supply based on a comparison result. The electric leakage detection apparatus also includes a discharge determination unit that compares the voltage detected by the voltage detector to a second threshold lower than the first threshold and determines whether the detection voltage becomes lower than the second threshold by a discharge of the coupling capacitor. The pulse generator generates a new pulse when the discharge determination unit determines that the detection voltage becomes lower than the second threshold.

Abstract: An electric leakage sensing apparatus includes a pulse generator that supplies a pulse to a coupling capacitor, a voltage detector that detects a voltage at the coupling capacitor, an electric leakage determination unit that compares the voltage detected by the voltage detector to a threshold and determines existence or non-existence of an electric leakage of a DC power supply based on a comparison result, a pre-check circuit that puts the DC power supply into a pseudo electric leakage state, a diagnostic unit that diagnoses whether the electric leakage determination unit determines that the electric leakage exists when the DC power supply is put into the pseudo electric leakage state, and terminals to which cables are connected. A current route from the pulse generator to the pre-check circuit through the coupling capacitor and the cables is formed when the DC power supply is put into the pseudo electric leakage state.

Abstract: A surfactant is added to a polymer solution (21) which is a coating fluid comprising an organic solvent and a polymer. The surfactant contains a fluorine atom and reduces the surface tension of the coating fluid. The coating fluid (21) is applied to a casting band (26) as a support. Dew condensation is caused to occur on the surface of the polymer film (40) formed by coating fluid application. The organic solvent and droplets are vaporized to thereby cause droplets to come into the film and form voids. By the use of the polymer solution (21), which comprises a mixture of an organic solvent, a polymer, and a fluorine-atom-containing surfactant for surface tension reduction, a structure having such fine pores is formed and a film (12) of a honeycomb structure is obtained. This film is reduced in the adhesion of dust, etc.
