Abstract: A polyphase rectifying apparatus is disclosed, which substantially solves the instability of the single-phase rectifiers without adding a special circuit element, thereby balancing the input voltages of the single-phase rectifiers. The polyphase rectifying apparatus, used in a two or more-phase system, comprises a single-phase rectifier assigned to each phase, and having first and second input terminals, wherein the single-phase rectifiers of each phase are star-connected and the first input terminal of each single-phase rectifier is connected to the corresponding phase and the second input terminals of each of the single-phase rectifiers are connected to each other; and a converter assigned to each phase, wherein the output from the single-phase rectifier of the relevant phase is input into the corresponding converter. The single-phase rectifiers for all the phases are controlled by a common control signal. Preferably, the converters of all the phases are also controlled by a common control signal.

Abstract: A cushioning molded product is provided which is produced by binding a vegetable fiber with a copolymer of a saccharide and an aliphatic dicarboxylic acid to conduct molding. Further a process is provided for producing a cushioning molded product from a copolymer of a saccharide and an aliphatic dicarboxylic acid, and a vegetable fiber, the process comprising (a) mixing or adhering the copolymer and the vegetable fiber, and (b) molding the resulting mixture into an intended shape by heating the mixture to bind the vegetable fiber with the copolymer.
