    Abstract: For use in gas chromatograph, there is provided a specimen capsule which has a sample wrapped in a foil or net of ferromagnetic metal. Also provided is a process for gas chromatography which comprises the steps of placing the specimen capsule in the vaporizer of the gas chromatograph, vaporizing the sample by means of alternative current induction and conducting necessary analysis on the resultant gases.

    Abstract: An industrial robot has a servo system allowing higher-speed robot operation than in conventional robots. The servo system includes a movable arm or arms pivotable about a pivot axis or axes and/or movable along an axis or axes. The servo system includes at least one movable arm pivotal about a vertical axis and associated with a servo motor for angular displacement within a substantially horizontal plane. A servo motor for driving the horizontally pivotable movable arm is mounted on a base frame of the robot. By mounting the servo motor on the base frame, the load on the movable arm can be reduced significantly so as to allow the movable arm to be operated at higher speeds. The servo system includes a controller adapted to control robot operation. The controller is programmed to actuate the working end of the robot arm along a predetermined non-linear trace, in which an acceleration zone is defined inthe vicinity of an initial position of the working end and a deceleration zone is defined in the vicinity of the predetermined working position and a relatively longer constant speed zone is defined between the acceleration zone and the deceleration zone.
