    • The present invention provides a design-for-product creating system and a design-for-product processing system. In the design-for-product creating system, a product vendor provides a user with a product design program, which enables the user to view virtual products that are graphics expressing designs created by the product vendor, and virtual part data representing virtual parts that constitute each virtual product. The user downloads the product design program and digital part data into his/her own computer, uniquely designs a product or part in a desired manner, and asks the product vendor over the Internet or the like to manufacture a product or part of the unique design. The product vendor in turn manufactures a product or part according to the desired unique design for a product or part provided by the user, and supplies the product or part of the unique design to the user. In the design-for-product processing system, the product vendor prompts the user to determine whether he/she will place an order for a product or part of the unique design created using the design-for-product creating system, whether he/she will have the product or part of the unique design sold on commission by the product vendor, or whether he/she will have the product or part of the unique design auctioned by the product vendor. The user can select at least one of the options.
    • 本发明提供了一种产品设计创建系统和产品设计处理系统。 在设计产品创建系统中,产品供应商向用户提供产品设计程序,其使用户能够查看作为产品供应商创建的图形表示设计的虚拟产品,以及表示构成的虚拟部件的虚拟部件数据 每个虚拟产品。 用户将产品设计程序和数字部件数据下载到他/她自己的计算机中,以期望的方式独特地设计产品或零件,并通过互联网等询问产品供应商来制造产品或独特设计的一部分 。 产品供应商又根据用户提供的产品或部件的所需独特设计制造产品或零件,并将产品或部分独特设计提供给用户。 在设计产品处理系统中,产品供应商提示用户确定他/她是否将为产品订购或使用产品设计创建系统创建的独特设计的一部分,无论他/她 将具有由产品供应商委托出售的产品或部分独特设计,或者他/她是否将具有由产品供应商拍卖的产品或独特设计的一部分。 用户可以选择至少一个选项。

    • There are disclosed a process for producing a polycarbonate through transesterification which comprises using, as a polymerization catalyst, (1) a combination of a nitrogen-containing organic basic compound and a quaternary phosphonium salt, (2) a tetraarylphosphonium salt having a specific chemical structure, or (3) a quaternary phosphonium salt having a specific chemical structure and containing a branched alkyl group; and a process for producing a polycarbonate which comprises the steps of preparing a polycarbonate prepoplymer by preliminary polymerization and thereafter polymerizing the resultant prepolymer in a state of a solid phase by the use of a quaternary phosphonium salt as a catalyst.By using any of these processes it is made possible to produce, in extremely high efficiency, a high-quality polycarbonate being excellent in appearance, heat resistance, hydrolysis resistance and the like.
