    Abstract: For eliminating a high-tension cable in order to improve the handling, the open type X-ray generating apparatus (1) in accordance with the present invention employs a mold power unit in which a high-voltage generating part, a grid connecting line, and a filament connecting line which attain a high voltage are molded with a resin, whereas the mold power unit is secured to the proximal end side of a tubular portion (2), whereby an apparatus of a type integrated with a power supply is realized. Since the high-voltage generating part, grid connecting line, and filament connecting line are confined within the resin mold as such, the degree of freedom in structure of the high-voltage generating part and the degree of freedom in bending the lines improve remarkably.

    Abstract: This invention concerns an electron beam generating system for high beam voltages in which the insulation between a grounded casing and the high-voltage electrodes is achieved by an insulating body surrounding the high-voltage electrodes with a small distance, so that the dimensions of the system are considerably smaller than with arrangements in which the insulation is primarily achieved by providing sufficient vacuum space about the high-voltage electrodes. The invention is further concerned with an automatically actuable replacement device for cathode holders, said replacement device being adapted to be controlled by monitoring means for at least one beam parameter so that the cathode holder under operation will be automatically replaced by a fresh cathode holder and cathode when the magnitude of the sensed beam parameter falls outside a predetermined range.

    Abstract: An indexing mechanism for an electron beam tube having many electron guns arranged on a turret, which rotates the turret to replace the gun being used when it fails, and to rotate the turret to serially activate the cathodes of the guns during construction of the tube. One indexing apparatus employs an indexing wheel fixed to the turret, a stack of bimetallic washers, and a heater for making the washers buckle to move a pawl member toward the indexing wheel to advance it. Another indexing apparatus includes an indexing wheel fixed to the turret, a thermal motor that can rotate a shaft, a latch arm on the shaft that pivots out of engagement with the indexing wheel during the first few degrees of shaft rotation, and a pair of driving members that rotate the wheel after the latch arm disengages from it.
