Title: Parallel multiplex inverter
Inventor: NISHITOBA MINORU
IPC: H02M7/493
Filed: 1990-09-06
Abstract: PURPOSE:To simplify the control circuit, to suppress ripple in output current and to ensure follow-up performance by performing current follow-up control of two inverters and correcting the hysteresis width of one inverter equivalently when the difference between a current command and the output current of inverter deviates from a predetermined range. CONSTITUTION:Three-phase voltage type inverters 1, 2 are connected, respectively, through reactors 81, 82 with a load 4 terminal. When the sum of detection currents ia1, ia2 deviates remarkably, in positive or negative side, from a current command ia*, 1 is outputted from a three-level comparator 132 and the input to a hysteresis comparator 121 is subjected to incremental/decremental correction through a coefficient unit 132. Consequently, when current ripples of both inverters 1, 2 overlap, output from the hysteresis comparator 121 on the side of the inverter 1 is inverted, which is equivalent to differentiate the hysteresis width from that of a comparator 122 on the side of the inverter 2, and then the switching phases of the inverters 1, 2 are shifted thus suppressing the current ripple.

IPC: B32B15/082
Filed: 1989-09-14
Abstract: PURPOSE:To obtain a coated metallic plate having excellent weatherproof property and capable of folding, by applying coating material containing as a main constituent a fluorine-containing copolymer which comprises units based on a fluoroolefin and units based on a macro-monomer having a hydrophilic moiety and which has a number average molecular weight not lower than a specified value.

Since the units based on a mcro-molecule having a hydrophilic moiety is incorporated in the fluorine-containing copolymer, an aqueous dispersed liquid prepared therefrom shows improved mechanical and chemical stability as well as enhanced film forming properties and water resistance of paint films. When the number of average molecular weight of the copolymer is less than 100,000, the resulting paint film has poor flexibil ity, and in application to a metallic plate, the resulting coated metallic plate has poor flexing properties; therefore, and aqueous dispersed liquid containing such a copolymer is unsuitable for producing precoated metals.
