Patent number: 5277539Abstract: A substrate conveying apparatus usable with a semiconductor manufacturing apparatus wherein a pattern of a mask is transferred onto a semiconductor wafer by exposing the semiconductor wafer to synchrotron orbital radiation or other exposure energy through a mask. The conveying apparatus transfers the semiconductor wafer to and from a wafer chuck while the surface thereof extends vertically, and/or transfers the wafer to and from a wafer cassette which contains a plurality of wafers horizontally. The apparatus includes a conveying hand having a gimbal mechanism for supporting the semiconductor wafer to assure the semiconductor wafer transfer to and from the wafer chuck while the wafer is vertical. When the semiconductor wafer is transferred to and from a wafer cassette, the apparatus is provided with a correcting mechanism for correcting the attitude of the conveying hand to prevent the semiconductor wafer from contacting the wafer cassette.Type: GrantFiled: May 10, 1993Date of Patent: January 11, 1994Assignee: Canon Kabushiki KaishaInventors: Shin Matsui, Takao Kariya, Nobutoshi Mizusawa, Ryuichi Ebinuma, Shunichi Uzawa

Patent number: 5183366Abstract: An extendable boom assembly is mounted on a platform or a base for longitudinally pivotally moving a drill rod between a rod rack and a drill rig in a position in alignment with the drill string axis regardless of whether the drilling direction is vertical or is angularly positioned relative to the vertical direction. The boom assembly is mounted for pivotal movement with the track assembly and transverse movement relative thereto, the track assembly being mounted on a drill rig platform. The upper end of the boom assembly mounts a jaw assembly for releaseably gripping a drill rod, the jaw assembly being mounted for limited pivotal movement about a horizontal axis and is of a design not requiring the rods being in a particular spaced relationship relative to one another. The gripping assembly jaws and the limited pivotal movement results in the rod to be transferred being pivoted to a position parallel to the main boom arm central axis as the rod is being clampingly engaged and moved away from the rod stack.Type: GrantFiled: December 4, 1990Date of Patent: February 2, 1993Assignee: Longyear CompanyInventor: Ivor N. Paech
