Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 179 words
A horizontal/vertical conversion transporting apparatus for a vertical heat treatment device, comprising: a table movable along a surface of a base; a column extending upward on said movable table and rotatable about an axis of rotation extending along a longitudinal direction thereof: a support arm movable along the longitudinal direction of said column; a conversion arm rotatable about an arm shaft thereof as an axis of rotation and mounted on said support arm; an upper boat hand mounted at one end of said conversion arm; a lower boat hand mounted at the other end of said conversion arm; means for changing a mounting angle of said lower or upper boat hand with respect to said conversion arm so as to stably set a distance between said lower and upper boat hands; and means for compensating for backlash of a mechanical mechanism arranged on said conversion arm, said backlash occurring between said conversion arm and said lower or upper boat hand upon a change in mounting angle of said lower or upper boat hand with respect to said conversion arm.
Claim 2
Dependent Claim 179 words
A horizontal/vertical conversion transporting apparatus for a vertical heat treatment device, comprising: a table movable along a surface of a base; a column extending upward on said movable table and rotatable about an axis of rotation extending along a longitudinal direction thereof: a support arm movable along the longitudinal direction of said column; a conversion arm rotatable about an arm shaft thereof as an axis of rotation and mounted on said support arm; an upper boat hand mounted at one end of said conversion arm; a lower boat hand mounted at the other end of said conversion arm; means for changing a mounting angle of said lower or upper boat hand with respect to said conversion arm so as to stably set a distance between said lower and upper boat hands; and means for compensating for backlash of a mechanical mechanism arranged on said conversion arm, said backlash occurring between said conversion arm and said lower or upper boat hand upon a change in mounting angle of said lower or upper boat hand with respect to said conversion arm.
Claim 3
Dependent Claim 21 words
An apparatus according to claim 1, wherein said upper and lower boat hands comprise vertical support portions for supporting the article.
Claim 4
Dependent Claim 19 words
An apparatus according to claim 2, wherein said vertical support portions are formed at portions of two two-articulated fingers.
Claim 5
Dependent Claim 36 words
An apparatus according to claim 1, wherein said means for changing the mounting angle of said lower or upper boat hand with respect to said conversion arm is a cylinder mechanism mounted on said conversion arm.
Claim 6
Dependent Claim 35 words
An apparatus according to claim 1, wherein said base is arranged between a transfer unit and a horizontal transporting unit, and said movable table is reciprocated between said transfer unit and said horizontal transporting unit.
Claim 7
Dependent Claim 22 words
An apparatus according to claim 1, wherein the article is a wafer boat which stores a large number of semiconductor wafers therein.
