摘要:
A system and method for correcting alignment of a product on a tool and, more particularly, to a system and method for correcting alignment of a wafer on a chuck of a tool. The system is a tool comprising at least one contact near a circumference of the tool and a grounded contact proximate to the at least one contact. The method comprises measuring current on each branch of a circuit and calculating an angle of a wafer based on a difference in the current on each branch of the circuit.

A sample stage for performing measurements using an optical metrology system includes at least one sample section for retention of a sample, and components for controlling orientation of the sample section with relation to the optical metrology system. A method and a computer program product are provided.

An aerial assembly comprising an upright tower of the type having attached vertical sections and an aerial standard carriage slidably attached to the tower and slidable along the tower, said tower serving the main upholding strength of the entire assembly and yet also serving as a guide-track.
摘要:
A sight glass assembly generally consisting of a first housing section having an opening therethrough mountable on a vessel wall, a second vessel section having an opening therethrough registrable with the first housing section opening when the first housing section is disposed in assembled relation with the second housing section, a pair of lenses disposed in the housing sections across the openings thereof, provided with beveled surfaces along the mating surfaces thereof, a packing member disposed between annular side walls of the lenses and the housing sections, and means for urging the housing sections together to compress the packing material and cause it to expand laterally to place the lenses in radial compression to maintain their structural integrity upon being fractured. The inner wall of the packing engaging the annular side walls of the lenses is provided with an annular recess registrable with the mating surfaces of the lenses which permits material of the packing to flow therein during compression thereof and thus avoid such material from being forced between the beveled edges of the lenses to force the lenses apart by a wedging action.
摘要:
A sight glass assembly comprising a housing adapted to be mounted on a wall, the housing having a bore therethrough, the housing bore having an enlarged section providing a shoulder, a lens disposed in the enlarged bore section and seated on the shoulder, at least one deformable O-ring mounted on the lens and disposed between a periphery of the lens and a wall of the enlarged bore section of the housing, a retainer member threadedly mounted on the housing, the retainer member having a bore therethrough disposed in alignment with the housing bore when the retainer member is threadedly munted on the housing, the retainer bore having an enlarged section providing a shoulder and the lens being disposed between the housing and the retainer shoulders, the retainer member having a member receivable within the enlarged housing bore section between the housing and the lens when the retainer member is threadedly mounted on the housing for compressing the O-ring against the housing shoulder and causing the O-ring to expand laterally and place the lens in peripheral compression, and a shoulder provided on the retainer member for restricting the travel of the compression member into the enlarged housing bore section.
