    • A hermetic reciprocating compressor includes a crankshaft stopper with an integrally formed resonance reducer portion. The crankshaft stopper is attached to the upper inner portion of a sealed casing of a compressor to restrict the movement of a motor portion and a compression device portion. The resonance reducer portion of the crankshaft stopper increases the rigidity of the sealed casing by reducing the resonance of the sealed casing. Since the vibration produced and transmitted to the sealed casing during the operation of the compressor is absorbed or damped by the crankshaft stopper with the resonance reducer portion, the resonance of the sealed casing is reduced and/or eliminated. Accordingly, overall noise caused by resonance of the sealed casing can be reduced.
    • 气密往复式压缩机包括具有整体形成的共振减速部分的曲轴止动器。 曲轴止动件附接到压缩机的密封壳体的上部内部,以限制电动机部分和压缩装置部分的移动。 曲轴止动器的共振减速器部分通过减小密封壳体的共振来增加密封壳体的刚度。 由于在压缩机运转过程中产生并传递到密封壳体的振动被具有共振减速部分的曲轴止动器吸收或阻尼,所以密封壳体的共振被减少和/或消除。 因此,可以降低由密封壳体的共振引起的整体噪声。

    • Disclosed are method and apparatus of restricting a data access. In particular, disclosed are method and apparatus for restricting an access to downloaded data to be possible only in permitted area or permitted time. A method for restricting data access of the invention, comprising: downloading data having information about an accessible area and a neighboring range of the area to a mobile communication terminal; reading-out the area and the neighboring range information from the data and checking a current position of the mobile communication terminal when a user requests an access for the downloaded data; and accessing to the data if the mobile communication terminal is located on the accessible area. According to the invention, it is also possible to induce the user into specific area in which the access to the data is possible, in specific time.
    • 公开了限制数据访问的方法和装置。 特别地,公开了用于仅在允许的区域或允许的时间内限制对下载数据的访问的方法和装置。 一种用于限制本发明的数据访问的方法,包括:将具有关于所述区域的可访问区域和相邻范围的信息的数据下载到移动通信终端; 当用户请求下载数据的访问时,从数据中读出区域和相邻范围信息并检查移动通信终端的当前位置; 以及如果所述移动通信终端位于所述可访问区域上,则访问所述数据。 根据本发明,也可以在特定时间内将用户引导到可以访问数据的特定区域。
