    • A vortex unit suitable for providing a desired environment for a semiconductor process may include a vortex tube and a semiconductor processing device suitable for performing a semiconductor processing function. The vortex tube includes an air inlet for receiving compressed air, a first air exhaust for outputting an air stream having a temperature greater than the received compressed air, and a second air exhaust for outputting an air stream having a temperature lower than the received compressed air. The semiconductor processing device is connected to the second air exhaust of the vortex tube so that the semiconductor processing device receives a cooled air stream from the vortex tube, the cooled air stream providing an environment suitable for enabling the semiconductor processing device to perform the semiconductor processing function.
    • 适于为半导体工艺提供期​​望环境的涡流单元可以包括适于执行半导体处理功能的涡流管和半导体处理装置。 涡流管包括用于接收压缩空气的空气入口,用于输出温度大于接收到的压缩空气的空气流的第一排气和用于输出温度低于接收的压缩空气的空气流的第二排气 。 半导体处理装置连接到涡流管的第二排气管,使得半导体处理装置从涡流管接收冷却的空气流,冷却的空气流提供适于使半导体处理装置执行半导体加工的环境 功能。

    • A wagering game apparatus and method is provided which permits the random selection of prizes for games such as blackjack, poker, and electronic games. A side wager is placed in a receptacle or designated area which indicates to the dealer that the player wishes to participate in the random jackpot selection portion of the game. If a random event occurs, such as the player being dealt a preselected combination of cards, the player or dealer may activate the random prize selection process. The random prize selection is performed by a computer which uses a random generated number to select a prize from a pay table. The prize may be displayed on or near the gaming table. The player is then awarded the random jackpot amount.
    • 提供了一种投注游戏装置和方法,其允许随机选择诸如二十一点,扑克和电子游戏的游戏的奖品。 侧面赌注被放置在插座或指定区域中,该区域向经销商指示玩家希望参与游戏的随机累积奖金选择部分。 如果发生随机事件,例如玩家被预先选择的卡片组合,玩家或经销商可以激活随机奖品选择过程。 随机奖品选择由使用随机生成号码的计算机执行以从付费表中选择奖品。 奖品可能会显示在游戏桌上或附近。 然后,玩家将获得随机累积奖励金额。
