A method of manufacturing a cathode ray tube employs an assembly of a frit jig and a flexible bolt for use during the aligning and sealing process of the glass cone and display screen components of a cathode ray tube. The flexibility provided by the bolt reduces the risk of damage to the glass parts of the cathode ray tube during the heat steps involved in the sealing process. Preferably, the bolt comprises a resilient metal pin that is flexible in a direction transverse to the longitudinal axis of the bolt. The bolt comprises a hollow part having a central bore with an opening and a head, the central bore extending substantially parallel to the longitudinal axis of the bolt, and the metal pin being comprised in the hollow bolt. The metal pin extends from the head through the bore over a length larger than that of the bore.

In an X-ray analysis apparatus, a moving mechanism is provided by a main guide member along which a main slide device can be displaced. Rotatably connected with the main slide device is a detector guide member along which a detection slide device is displaced. The main slide device, as well as the detection slide device, and an axis of rotation relative to an end of the main guide member are connected to a common central axis by respective arms which can be mutually rotated with them. The main slide device and the detection slide device can each be equipped with a drive motor where the motor for the main slide device is preferably driven first, and the motor for the detector slide device is driven by signals derived from displacing the main slide device. The rotatable arms ensure an optimum orientation of a crystal holder incorporated onto the main slide device, and a detection holder incorporated onto the detector slide device with respect to each other and with respect to a point of focus of an X-ray source.
