    • PURPOSE: A precision casting method and a mold therefor are provided to solve the problems caused by the riser effect and the end effect, thereby obtaining a precise and uniform cast iron. CONSTITUTION: The precision casting method comprises the modeling step(S10) of forming a wax model including a riser model having a volume more than ten-times of a casting forming part and a cast iron model connected thereto; the investing step(S20) of investing the wax model in a flask and filling the inside of the flask with an investment; the dewaxing-burn out step(S30) of heating the hardened investment to melt and remove the wax, thereby forming a mold; the casting step(S40) of mounting the mold on a casting machine, pouring a weld pool into the mold and leaving the mold in air to be hardened so that due to the difference of the cooling speed in mold, the cast iron in a runner is broken and heat conduction with outside is blocked; and the finishing step(S50) of performing the separation of the cast-iron from the mold and the post-treatment of the separated cast iron.
    • 目的:提供精密铸造方法及其模具,以解决由立管效应和最终效应引起的问题,从而获得精确均匀的铸铁。 构成:精密铸造方法包括形成蜡模型的建模步骤(S10),其包括体积大于铸造成形部分的十倍以上的立管模型和与其连接的铸铁模型; 投资步骤(S20)将蜡模型投资在烧瓶中并投资填充烧瓶内; 脱蜡烧结步骤(S30),加热硬化的投料以熔融并除去蜡,从而形成模具; 将铸模安装在铸造机上的铸造步骤(S40),将熔池注入模具中并将模具留在空气中以使硬化,使得由于模具中的冷却速度的差异,流道中的铸铁 被破坏,外界的热传导阻塞; 以及执行铸铁从模具分离以及分离的铸铁的后处理的精加工步骤(S50)。

    • PURPOSE: A goods information search method is provided to search for information on goods over a wireless communication network if a user inputs goods model name at a mobile terminal. CONSTITUTION: The method comprises several steps. First, a consumer, browsing a store, inputs a model name on desired goods at a mobile phone or a PDA to obtain information on specific goods(ST101). A web server checks a phone number of the mobile phone or the PDA, and authenticates the consumer by using member data stored at a database(ST102). The web server requests a search server to search for information on the input specific goods(ST103). The search server searches for information on the input goods in a database by executing a search engine(ST104). The search server checks a price of the goods to be sold at other store or a price of a competitive goods, and transmits the searched information to the mobile phone or the PDA(ST105). In a case that the consumer releases an access to the web server, the web server transmits member data and access time to a billing server for calculating an information usage fee according to the byte rate billing scheme(ST107).
    • 目的:如果用户在移动终端输入商品型号名称,则提供商品信息搜索方法来搜索无线通信网络上的商品信息。 构成:该方法包括几个步骤。 首先,消费者浏览商店,在移动电话或PDA上输入所需商品上的型号以获得关于特定商品的信息(ST101)。 Web服务器检查移动电话或PDA的电话号码,并通过使用存储在数据库中的成员数据对消费者进行认证(ST102)。 网络服务器请求搜索服务器搜索关于输入特定商品的信息(ST103)。 搜索服务器通过执行搜索引擎来搜索数据库中的输入商品的信息(ST104)。 搜索服务器检查在其他商店销售的商品的价格或竞争商品的价格,并将搜索到的信息发送到移动电话或PDA(ST105)。 在消费者释放对web服务器的访问的情况下,Web服务器将成员数据和访问时间发送到计费服务器,以根据字节码计费方案计算信息使用费用(ST107)。
