摘要:
Insulating ceramic parts for insulating collector electrodes in a traveling wave tube and a vacuum envelope are formed in a cylindrical shape in which the central axis of the inner diameter diverges from the central axis of the outer diameter and are constructed such that holes are provided in portions of the insulating ceramic parts where the thickness in the radial direction is great, and high-voltage leads for supplying prescribed voltages to said collector electrodes from the exterior pass through these holes.

摘要:
A driving method for a gas discharge display panel especially of a large size. The invention uses a gentle rise-up waveform or stepwise rise-up waveform of the sustaining pulse to allow a more operational margin while not increasing load to the driving circuit.
摘要:
A work holding apparatus is a work holder for holding a work in a predetermined position in relation to a basic member. A base column is rotatably supported astride on two sets of base plates. Holding fixtures are removably mounted on each side of the base column, such that different types of works can be supported and clamped by the holding fixtures. An indexing-rotation driving device rotates the base column such that it may be applicable to various types of works, thereby facilitating the holding of many types of works and the replacement of supporters and clamps. Furthermore, the base plate for supporting the base column is divided into two sets to reduce the weight of the base plate moving parts, and a base plate synchronizing means is provided to insure synchronized operation of the two base plates.
