    摘要： A filter membrane has at its flow in side a first metal fibre web, at least two metal fibre layers, and a fine and at least one coarser fibre layer. The fine fibre layer is located at the flow in side of the filter membrane and the at least one coarser fibre layer is located downstream of the fine fibre layer. The filter membrane has at its flow out side, a stack of one or more first two-dimensional metal structures with constant and regular openings. The filter membrane also has at least one set formed by a second metal fibre web and a stack of one or more second two-dimensional metal structure with constant and regular openings; the at least one set is provided in between the stack of one or more two-dimensional metal structures that are having constant and regular openings, and the first metal fibre web.

    摘要： A method for controlling speed of a single phase induction motor using frequency variation, including the steps of generating an operation start signal and a speed command signal according to a user's selection, outputting a digital data for formation of a sinusoidal wave signal of a desired frequency, to converting means at an interval of a predetermined time period set by a timer to thereby generate the sinusoidal wave signal of the frequency desired by the user, generating the sinusoidal wave based on the digital data, comparing the sinusoidal wave with a triangular signal for controlling a speed of a motor, and converting a DC voltage from a power source into an AC voltage of a frequency band desired by the user to thereby operate the motor. An apparatus for controlling the speed of a single phase induction motor is also provided.
