摘要:
A stage apparatus enables easy position alignment at a real installation site. Mounts 25 having sub base plates 21 arranged thereon are provided on carriages 25 and thereby constitute sub mounting tables 20a to 20d; and the mounts 25 are fixed to a main mounting table 10 having a main base plate 11. The positions of main base plate 11 and sub base plates 21 are aligned with each other by adjustment mechanisms 30 provided on the sub mounting tables 20a to 20d. As main positioning members 16 and sub positioning members 241, 242 are arranged on the main mounting table 10 and sub mounting tables 20a to 20d, separation can be performed so that a state of position alignment is restorable. Accordingly, position alignment is easy when assembling after transportation.

A stage apparatus that achieves a high accuracy in assembling and enables easy work at a real installation site. In a stage apparatus of the present invention, sub rails are arranged on respective sub base plates, which are connected respectively with the first and second main rails on a main base plate to extend the first and second main rails. Accordingly, when the sub base plates are fixed to the main base plate 11 with positional alignment performed therebetween, the accuracy in positional alignment of the sub base plates which has already been fixed to the main base plate is not affected.
摘要:
To enable division for transportation and secure proper treatment on a substrate to be treated, the present invention provides a stage apparatus (11) including a substrate holding plane which holds a substrate to be treated, a pair of guide frames (13X1), (13X2) oppositely disposed with the substrate holding plane sandwiched therebetween, and a gantry (13Y) which is movably held on upper surfaces of the pair of guide frames (13X1), (13X2). The stage apparatus (11) is composed of a first structure V1 which includes one guide frame (13X1), a second structure V2 which includes the other guide frame (13X2), and a third structure V3 which includes the gantry (13Y). Thus, even if the stage apparatus is large, since it can be divided into the structures V1 to V3, the stage apparatus can be transported by land. In addition, since there are no joints on a moving path of the gantry (13Y), the stage apparatus can properly treat the substrate without causing deterioration of moving accuracy.

To obtain a stage apparatus that can be divided for land transportation and can properly treat a substrate to be treated, the present invention provides a stage apparatus including a substrate holding plane which holds a substrate to be treated W, a pair of guide frames (13X) oppositely disposed with the substrate holding plane sandwiched therebetween, a gantry (13Y) which extends over the pair of guide frames (13X) and which is movably held by the pair of guide frames (13X), and a substrate treatment unit (14) which is disposed on the gantry (13Y). The guide frames (13X) each are composed of a connected structure of a main frame portion (15A) which forms a moving path (work region R1) of the gantry (13Y) necessary for the substrate treatment unit (14) to perform a substrate treatment, and a sub frame portion (15B) which is connected to one end portion or both end portions in a longitudinal direction of the main frame portion (15A) and which forms a moving path to a non-work position (non-work region R2) of the gantry (13Y).
摘要:
A transport apparatus which can properly transmit a rotary driving force of a rotating motor to a transport arm and can correctly detect an angle of rotation of a rotary driving shaft, thereby transporting an object to be transported in a transport unit to a correct position. The transport apparatus includes: a housing having an airtight structure; first to third driving shafts that are provided in the housing to be independently rotatable around a predetermined coaxial rotary shaft; permanent magnets arranged at predetermined positions of the first to third driving shafts, respectively; and electromagnetic coils provided in the housing to correspond to the respective permanent magnets. Driving currents are supplied to the electromagnetic coils based on predetermined information, so as to move the first to third driving shafts. The object to be transported is transported by first and second linkages fixed to the first to third driving shafts.

This invention provides a transport apparatus having a simple configuration that can reduce its turning radius and transport semiconductor devices at high speed. The transport apparatus comprising the first and second arms having at a first end of each thereof a rotary drive shaft being arranged coaxially, and third and fourth arms rotatably linked at respective the first ends thereof to the respective second ends of the first and second arms. The second ends of the third and fourth arms are supported around centers of coaxially arranged spindles, respectively. The transport apparatus further comprises an articulating mechanism having an attitude control mechanism adapted to apply rotary forces with opposite phases to the respective spindles arranged at the third and fourth arms.
摘要:
A head with a pick-up coil is attached to a supporter so that the head is freely movable along the direction perpendicular to the surface of a superconductor. Fluid spouted from the spout hole of the head maintains the height (gap space) of the head from the surface. The head is firmly fixed to the supporter in the direction along the surface. Since the relative position of the head in the direction along the surface of the superconductor is changable by drive means for moving the superconductor or the head, the distribution of the magnetic flux which is trapped in the superconductor is measured by scanning the surface of the superconductor with pick-up coil.
摘要:
An assembling method that is high in assembly accuracy and easily performed at the actual installation site is provided. In this method, the sub base plates on the sub mounting tables are aligned with respect to a main base plate on a main mounting table at a temporary installation site, and the state thereof is maintained. Then, the main mounting table and the sub mounting tables are separated from each other to be transferred to the actual installation site, and the positioning state is restored at the actual installation site. Since a positional alignment can be performed at the temporary installation site, the work required at the actual installation site can be reduced. Furthermore, since a fine adjustment can be performed at the actual installation site, the accuracy in the positional alignment can be improved.

摘要:
A transport apparatus includes first and second linkages. The first linkage includes first and third arms that can be rotated around a coaxial rotary shaft of first through third driving shafts coaxially arranged, and transports a first carrier. The second linkage includes a second arm and the third arm that can be rotated around the coaxial rotary shaft of the first through third driving shafts, and transports a second carrier. The first and second linkages are arranged to allow the first and second carriers to move beyond the coaxial rotary shaft of the first through third driving shafts without interfering with each other.
