Abstract
Abstract An x-ray tube target element in which a target disk portion, a stem portion and a base portion are integral. The elements are composed, alternatively, of metals frequently used for target disks alone or of graphite. A layer of an alloy, such as tungsten-rhenium, disposed circularly on a face of the target disk substrate constitutes the focal track of the target. The base of the element is adapted for coupling it directly to the anode rotor assembly.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
60 words
A unitary target element (13, 60) for an x-ray tube having a rotor assembly (20), the element characterized by a circular target body portion (40, 61), a stem portion (41,62) integral with and extending coaxially from said body, and a base portion (42,63) integral with said stem and spaced from the body portion,for mounting the element to said rotor assembly.
Claim 2
Dependent Claim
60 words
A unitary target element (13, 60) for an x-ray tube having a rotor assembly (20), the element characterized by a circular target body portion (40, 61), a stem portion (41,62) integral with and extending coaxially from said body, and a base portion (42,63) integral with said stem and spaced from the body portion,for mounting the element to said rotor assembly.
Claim 3
Dependent Claim
64 words
The unitary target element defined in Claim 1 characterized in that the base portion is circular and extends radially and integrally from said stem portion and is spaced from said target body, said rotor assembly having a circular part and said base portion having a circular recess (43) on a side remote from target body for fitting (44) said base portion on said rotor.
Claim 4
Dependent Claim
29 words
The unitary target element defined in Claim 1 characterized in that the base portion of the integral element has an external thread (65) for coupling it to said rotor.
Claim 5
Dependent Claim
31 words
The target element as defined in any one of claims 1, 2 or 3 characterized in that the integral target body portion, stem portion and base portion are composed of graphite.
Claim 6
Dependent Claim
45 words
The target element as defined in any of claims 1, 2 or 3 characterized in that the target body portion, stem portion and base portion are composed of a metal selected from the group consisting of tungsten and molybdenum and alloys of tungsten and molybdenum.
Claim 7
Dependent Claim
45 words
The unitary target as defined in any one of claims 1, 2 or 3 characterized in that the stem portion has an axially extending hold (50) for reducing its cross sectional area to thereby reduce heat conduction from said target body portion to said rotor.
Claim 8
Dependent Claim
69 words
7: The unitary target element as defined in claim 1 characterized in that the circular target body portion, stem portion and base portion for mounting are composed of graphite and a face of said target body portion opposite of the stem is beveled to define an annular focal track region (52), and at least a portion of said region has a circular layer of tungsten-rhenium alloy bonded to it.
Claim 9
Dependent Claim
65 words
The unitary target as defined in claim 1 characterized in that the circular target body portion, stem portion and base portion are composed of molybdenum and a face of said target body opposite of said stem portion is beveled to define an annular focal track region (52) and at least a portion of said region has a circular layer of tungsten-rhenium alloy bonded to it.
