Abstract
The present inventive concept provides a method for manufacturing a filament including the steps of inserting and bonding an electrode having a desired length into a through-hole of a plate-shaped base to form a first part; bonding a wire having a desired length to one surface of a plate-shaped disc to form a second part; and bonding the electrode of the first part and the wire of the second part to form a filament, a filament manufactured by said method, and an X-ray tube having said filament.
Claims16
A method for manufacturing a filament including the steps of:
- inserting and bonding an electrode having a desired length into a through-hole of a plate-shaped base to form a first part;
- bonding a wire having a desired length to one surface of a plate-shaped disc to form a second part;
- and
- bonding the electrode of the first part and the wire of the second part to form a filament.
An X-ray tube including a filament configured to emit electrons by the supply of power;
- a target configured to receive the electrons from the filament and emit X-rays;
- a body configured to seal the filament and the target while facing each other;
- and a cap configured to emit heat in close contact with the target, wherein the filament includes a plate-shaped base having a desired thickness;
- an electrode provided through at least two regions of the base;
- a wire connected to one end of the electrode;
- and a plate-shaped disc connected to the other end of the wire that is opposite to one end connected to the electrode.
