Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A wafer transfer device for a pair of wafer carriers of the type having aligned side grooves for receiving a number of wafers and front and rear openings with only a first of the openings being wide enough to allow the wafers to enter and leave the wafer carrier, said device comprising: a base having an upper surface; and a wall member secured to the base and extending upwardly therefrom; said surface adapted to support a pair of wafer carriers with the first openings thereof abutting each other and with the grooves of the wafer carriers aligned with each other, said wall member adapted to enter the other opening of the adjacent wafer carrier as the wafer carriers move over the surface toward the wall member, so that the wafers will be shifted by the wall member from the grooves of the first wafer carrier to the grooves of the second wafer carrier.
Claim 2
Dependent Claim
153 words
A wafer transfer device for a pair of wafer carriers of the type having aligned side grooves for receiving a number of wafers and front and rear openings with only a first of the openings being wide enough to allow the wafers to enter and leave the wafer carrier, said device comprising: a base having an upper surface; and a wall member secured to the base and extending upwardly therefrom; said surface adapted to support a pair of wafer carriers with the first openings thereof abutting each other and with the grooves of the wafer carriers aligned with each other, said wall member adapted to enter the other opening of the adjacent wafer carrier as the wafer carriers move over the surface toward the wall member, so that the wafers will be shifted by the wall member from the grooves of the first wafer carrier to the grooves of the second wafer carrier.
Claim 3
Dependent Claim
17 words
A device as set forth in claim 1, wherein the wall member is in a vertical plane.
Claim 4
Dependent Claim
59 words
A device as set forth in claim 1, wherein the wall member has a lower margin spaced above said surface to accommodate a part of the structure of the first wafer carrier to permit the wafer carrier to shift past the wall member and to allow the wall member to enter the one opening of the first wafer carrier.
Claim 5
Dependent Claim
22 words
A device as set forth in claim 1, wherein is included a plate coupled with the wall member remote from said surface.
Claim 6
Dependent Claim
63 words
A device as set forth in claim 1, wherein said wall member extends upwardly from the surface near one end of the base, there being a slot between a major portion of the wall member and said surface, there being a plate on the wall member at the upper extremity thereof, there being a second slot between the wall member and the plate.
Claim 7
Dependent Claim
35 words
A device as set forth in claim 1, wherein is included a pair of rails secured to the base on opposite sides of the surface, said rails extending upwarly from the plane of the surface.
Claim 8
Dependent Claim
29 words
A device as set forth in claim 1, wherein said wall member has a hole therethrough for receiving the fingers of the hand to facilitate carrying of the device.
Claim 9
Dependent Claim
28 words
A device as set forth in claim 1, wherein said margin of the wall member comprises a flat face for engaging the wafers of said first wafer carrier.
Claim 10
Dependent Claim
32 words
A device as set forth in claim 1, wherein the length of the face is at least equal to the distance between the uppermost and lowermost wafers of the first wafer carrier.
Claim 11
Dependent Claim
52 words
A device as set forth in claim 1, wherein is provided means defining an upper slot and a lower slot above and below the wall member, the first wafer carrier having upper and lower webs receivable in the slots when the first wafer carrier moves along the wall member past said margin.
