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.
Claims7
An open type X-ray generating apparatus comprising;
- a tubular portion having an electron path, the inside of said tubular portion being vacuumed by a pump;
- a mold power unit secured to a proximal end side of said tubular portion, said mold power unit having a high-voltage generating part and connecting lines electrically connected to said high-voltage generating part which are enclosed with an electrical insulating mold therein;
- a target provided in said tubular portion;
- an electron gun mounted to said mold power unit so as to electrically connect said connecting lines of said mold power unit and opposed to said target with said electron path interposed therebetween.
An open type X-ray generating apparatus comprising;
- a tubular portion, adapted to be vacuumed by a pump, having a coil part therewithin and an electron path surrounded by said coil part;
- a target provided in said tubular;
- a mold power unit, secured to a proximal end side of said tubular portion, having a high-voltage generating part and grid and filament connecting lines electrically connected to said high-voltage generating part which are enclosed within a resin mold;
- and
- an electron gun having a replaceable filament part electrically connected thereto by way of said filament connecting line and a grid part, electrically connected to said grid connecting line, surrounding said filament part, said electron gun being attached to said mold power unit so as to oppose said target with said electron path interposed therebetween.
