    • A chromatograph provided with a new and improved purge system for the sample introducing chamber, wherein a first carrier fluid supplying conduit is connected to the chamber adjacent to the sample injection port thereof and a second carrier fluid supplying conduit is connected to the fluid path between the column and the connecting point of the first conduit and the chamber. When a sample is injected into the chamber for analysis, the carrier fluid is supplied into the chamber through the first conduit to carry the sample components into the column, and when the analysis has been completed, the carrier fluid is introduced into the fluid path through the second conduit to flow upstream through the chamber, thereby preventing any of the sample components remaining in the chamber from entering the column to cause "ghost" peaks or baseline fluctuation in the chromatogram.
    • 一种色谱仪,其具有用于样品引入室的新的和改进的吹扫系统,其中第一载体流体供应管道连接到邻近其样品注入端口的室,并且第二载体流体供应管道连接到流体路径 柱和第一导管和室的连接点。 当将样品注入到室中用于分析时,载体流体通过第一导管供应到室中,以将样品组分携带到柱中,并且当分析完成时,载体流体被引入到流体路径中 通过腔室上游流动的第二导管,从而防止残留在腔室中的任何样品组分进入色谱柱,从而引起色谱图中的“重影”峰值或基线波动。

    • A sailing simulator comprising: a hull provided with a boom and a rudder; first supporting means for supporting the hull through the intermediary of springs for heeling motion; second supporting means for supporting the first supporting means for rotation about a vertical axis; and drive means for causing the first and second supporting means to effect heeling motion and rotation, respectively; and means operable in response to the handling of the boom and/or the rudder to control the drive means. An elastic means is interposed between the first supporting means and the drive means therefor so that the hull can be moved about the heeling axis by positional change of the weight of the trainee on the hull. Means is also provided for application of a reactive force to the boom as the boom and/or the rudder are handled.
    • 一种帆船模拟器,包括:设有吊杆和舵的船体; 第一支撑手段,用于通过弹簧中间的支撑船体来抬起运动; 第二支撑装置,用于支撑围绕垂直轴线旋转的第一支撑装置; 以及用于使第一和第二支撑装置分别实现向上运动和旋转的驱动装置; 以及响应于所述起重臂和/或所述舵的操纵而可操作以控制所述驱动装置的装置。 在第一支撑装置和其驱动装置之间插入弹性装置,使得船体可以通过船体上的受训者的重量的位置改变而围绕倾斜轴线移动。 还提供了当处理悬臂和/或方向舵时将手段施加到起重臂的反作用力。

    • A mass spectrometer comprising an ion source for producing an ion beam, an ion optical system having an entrance and an exit slit, and an ion detector. The ion optical system comprises a series combination of an energy dispersing unit and a mass dispersing unit. The energy dispersing unit comprises a toroidal electrical field having a deflection angle of 85.degree. to 95.degree. while the mass dispersing unit comprises a homogeneous magnetic field having a deflection angle of 85.degree. to 95.degree. and an entrance end face made concave as viewed from the entrance side of the ion beam when the apparatus is operated as a double focussing mass spectrometer of the reverse geometry type and an exit end face inclined 6.degree. to 14.degree. to the negative side from a position perpendicular to the axis of the ion optical system.
