    • An arcade game including an inclined playing surface and a coin directing mechanism. A coin hopper forces multiple coins through the coin directing mechanism and onto the playing surface for each activation of a button by the player. The player can direct the multiple coins in a desired direction down the playing surface using the directing mechanism. The coins roll toward one or more targets on the playing surface, and a game score is adjusted based on the targets that receive the coins. Indicators for the targets can highlight specific targets and goals during game play. A progressive bonus score can also be added to the game score when a progressive goal is achieved by the player. After the game is over, a tilting mechanism tilts the playing surface to clear the playing surface of coins that have not rolled into apertures and are resting on the playing surface.
    • 包括倾斜游戏表面和硬币导向机构的街机游戏。 硬币料斗通过硬币引导机构强制多个硬币,并且通过玩家每次激活按钮来强制播放表面。 玩家可以使用引导机构将多个硬币沿所需方向引导到玩游戏表面。 硬币朝向演奏表面上的一个或多个目标滚动,并且基于接收硬币的目标来调整游戏得分。 目标指标可以突显游戏过程中的具体目标和目标。 当玩家实现进步的目标时,也可以将渐进奖金分数添加到游戏得分中。 游戏结束后,倾斜机构倾斜播放表面以清除尚未滚动到孔中并在播放表面上的硬币的游戏表面。

    • A volume adjustable pipette, comprising a plunger mounted for movement in a housing to and from a stop to aspirate a fluid into and dispense the fluid from a tip extending from the housing. An axially moveable volume setting member in the housing defines the stop and a volume setting for the pipette and is axially moveable by a user turnable volume setting member. Turning of the volume adjusting member also controls a coarse volume setting means and a fine volume setting means, the course volume setting means being responsive to a relatively small turning of the volume adjusting member for moving the volume setting member a relatively large axial distance and the fine volume setting means being responsive to a relatively large turning of the volume adjusting member for moving the volume setting member a relatively small axial distance.
    • 一种体积可调移液管,包括柱塞,所述柱塞安装成用于在壳体内和从止动件移动以将流体吸入并从从壳体延伸的尖端分配流体。 壳体中的可轴向移动的体积调节构件限定止动件和移液管的体积设定,并且可由用户可转动体积设定构件轴向移动。 音量调节构件的转动还可以控制粗略的体积设定装置和微细体积设定装置,该音量设定装置响应于体积调节构件相对较小的转动,用于使音量调节构件移动相对较大的轴向距离, 微细体积设定装置响应于体积调节构件相对较大的转动而使体积调节构件移动相对小的轴向距离。
