    • The present invention relates to a sprue bush, and more particularly, to a sprue bush in which a cooling water flow channel is formed into a spiral shape so as to sufficiently improve an injected liquid temperature control range and thus improve the cooling function of the sprue bush. Forming the spiral cooling water flow channel within the sprue bush using a general machining technique may pose difficulties, and therefore, the sprue bush has a structure enabling separation into an upper body and a lower cover so as to enable the spiral cooling water flow channel to be easily formed within the sprue bush. In addition, a packing element is formed between the separated upper body and the lower cover so as to improve water-tightness in the cooling water flow channel. Thus, not only may functionality of the sprue bush be improved but reliability and component molding capability of an injection-molding apparatus using the sprue bush may also be improved, thereby improving the competiveness of the sprue bush, the injection-molding apparatus, and components molded by the injection-molding apparatus.
    • 浇道衬套技术领域本发明涉及一种浇道衬套,更具体地说,涉及一种浇道衬套,其中冷却水流道形成为螺旋形状,从而充分提高注入液体温度控制范围并因此改善浇道的冷却功能 衬套。 采用普通机械加工技术在浇道套内形成螺旋冷却水流通道可能会造成困难,因此,浇道套具有能够分离成上部本体和下部盖的结构,从而使螺旋形冷却水通道能够 容易在浇道衬套内形成。 另外,在分离的上体和下盖之间形成填充元件,以改善冷却水流动通道中的水密性。 因此,不仅可以改善浇道套的功能性,而且还可以提高使用浇道套的注射成型设备的可靠性和部件成型能力,从而提高浇道套,注塑成型设备和部件的竞争力 由注塑设备模制。

    • A wireless receiver and a wireless receiving method are provided wherein a frequency of a radio frequency (RF) is down-converted into a frequency of a substantially zero intermediate frequency (IF) signal or a substantially low IF signal. The down-converted signal may be filtered by an integrated filter having a low quality factor and then up-converted again into a particular IF signal, thereby integrating an external element. For example, a receiving device may receive a RF signal in a required band. A frequency down-converting device may down-convert a frequency so that a center frequency of the RF signal becomes zero. A channel select filtering device may select a required channel from the signals whose frequency is down-converted. An IF signal converting device may up-convert a frequency of the channel selected signal into a required IF. An IF processing device may extract a baseband signal after the converted IF signal is inputted and processed. An amplifying device may amplify a signal with a gain required in a process of converting a frequency.
    • 提供了一种无线接收机和无线接收方法,其中射频(RF)的频率被下变频成基本为零的中频(IF)信号或基本上低的IF信号的频率。 下变频信号可以由具有低质量因子的积分滤波器滤波,然后再次上变频成特定的IF信号,从而整合外部元件。 例如,接收设备可以接收所需频带中的RF信号。 降频转换装置可以降频转换频率,使得RF信号的中心频率变为零。 频道选择滤波装置可以从频率被下变频的信号中选择所需频道。 IF信号转换装置可以将频道选择信号的频率上变频成所需的IF。 IF处理装置可以在转换的IF信号被输入和处理之后提取基带信号。 放大装置可以放大具有在转换频率的过程中所需的增益的信号。
