Abstract
Abstract A closed-circuit TV inspection X-ray microscope characterized in that means for moving the specimen inside a shielded specimen chamber includes the specimen-chamber wall which supports a specimen manipulator and which is movable in its own plane. The microscope is mainly intended to measure hidden flaws in smallsize products having an opaque enclosure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
226 words
A closed-circuit TV inspection X-ray microscope comprising a shielded specimen chamber for accommodating an object to be inspected, an X-ray source for producing an X-ray beam having a fixed axis with respect to said chamber, said X-ray beam entering said specimen chamber for producing an X-ray shadow image of the object, an X-ray sensitive TV pick-up tube positioned on said axis to receive said image and convert the same into a videosignal, a TV monitor connected with said pick-up tube and having a screen on which the image of the inner structure of the object can be displayed, means for moving the object inside said specimen chamber along three mutually perpendicular coordinates, said means including a wall which bounds said chamber and encloses the same and which is movable in its own plane parallel to said axis of the X-ray beam, plate means on said wall which is movable in a direction perpendicular to the movement of said wall, a rod passing through said plate means into said specimen chamber, said rod being provided at the end thereof extending into said chamber with a grip means to fix the object thereat, and control means at the opposite end of the rod remaining outside said chamber for moving said rod into and out of said chamber in a direction perpendicular to the axis of the X-ray beam.
Claim 2
Dependent Claim
226 words
A closed-circuit TV inspection X-ray microscope comprising a shielded specimen chamber for accommodating an object to be inspected, an X-ray source for producing an X-ray beam having a fixed axis with respect to said chamber, said X-ray beam entering said specimen chamber for producing an X-ray shadow image of the object, an X-ray sensitive TV pick-up tube positioned on said axis to receive said image and convert the same into a videosignal, a TV monitor connected with said pick-up tube and having a screen on which the image of the inner structure of the object can be displayed, means for moving the object inside said specimen chamber along three mutually perpendicular coordinates, said means including a wall which bounds said chamber and encloses the same and which is movable in its own plane parallel to said axis of the X-ray beam, plate means on said wall which is movable in a direction perpendicular to the movement of said wall, a rod passing through said plate means into said specimen chamber, said rod being provided at the end thereof extending into said chamber with a grip means to fix the object thereat, and control means at the opposite end of the rod remaining outside said chamber for moving said rod into and out of said chamber in a direction perpendicular to the axis of the X-ray beam.
Claim 3
Dependent Claim
56 words
A closed-circuit TV inspection X-ray microscope as claimed in claim 1 wherein said rod comprises two parts, one of which carries said grip means fixed thereon, said parts being coaxially mounted for relative movement by said control means, said control means comprising fine-adjustment means for said parts of the rod and rough-adjustment means for said rod.
Claim 4
Dependent Claim
54 words
A closed-circuit TV inspection X-ray microscope as claimed in claim 1 comprising means for rotating the means which moveS the object around an axis perpendicular to the axis of the X-ray beam, whereby the orientation of the plane of coordinate movements of the object changes with respect to said axis of the X-ray beam.
Claim 5
Dependent Claim
73 words
A closed-circuit TV inspection X-ray microscope as claimed in claim 1 comprising two scales arranged parallel to the coordinate movements of the object to measure said movements, one of said scales being on said rod to move together therewith and the other being transparent and affixed to said wall, and an optical scale-reading device permanently attached to said plate means so that both said scales are simultaneously in the field of vision thereof.
Claim 6
Dependent Claim
56 words
A closed-circuit TV inspection X-ray microscope as claimed in claim 1 comprising means for producing on the screen of said monitor an image of two mutually perpendicular and independently movable cross-hair lines and means for bringing the center of said cross-hairs to the axis of the X-ray beam falling on the target of said pick-up tube.
