摘要： Provided is a transport method comprising judging whether there is a possibility that misalignment greater than or equal to a threshold value occurs between substrates to be layered that are held by a pair of substrate holders aligned and stacked by an aligning section, the misalignment occurring when the pair of substrate holders is transported from the aligning section to a pressure applying section; and if the judgment indicates that there is the possibility of misalignment, transporting the pair of substrate holders to a region other than the pressure applying section. Whether there is the possibility of misalignment may be judged based on acceleration of the substrate holders. Whether there is the possibility of misalignment may be judged based on acceleration of a transporting section that transports the substrate holders. Whether there is the possibility of misalignment may be judged based on relative positions of the substrate holders. Whether there is the possibility of misalignment may be judged based on relative positions of (i) a transporting section that transports the pair of substrate holders and (ii) one of the pair of substrate holders.

摘要： A radio-frequency coil has a first element and a second element both being adjacently arranged so as to nip a division/join portion. The first element has a first main loop portion provided along an arrangement plain surface and a first sub-loop portion provided along a surface substantially perpendicular to the arrangement plain surface. The second element has a second main loop portion provided along the arrangement plain surface and a second sub-loop portion provided facing the first sub-loop.

Circular rubber elastic valve elements (51 and 52) are attached to the valve shaft (12) and used for switching between a communication state where either one of the elastic valve elements is spaced away from an inner peripheral sealing surface of the valve accommodating hole (11) such that the supply port (20) and the respective output port (23 or 24) communicate with each other and a shut-off state where either one of the elastic valve elements comes in contact with the inner peripheral sealing surface such that the communication is shut off. Composite valve elements (61 and 62) each equipped with a circular reinforcement ring (63) and a rubber elastic seal (64) integrally provided to the reinforcement ring are attached to the valve casing (15), and each of the composite valve elements (61 and 62) switches between a communication state where the respective valve shaft output port (23 or 24) and the respective discharge port (21 or 22) communicate with each other and a shut-off state where the communication is shut off.

摘要： Charged-particle-beam (CPB) mapping projection-optical systems and adjustment methods for such systems are disclosed that can be performed quickly and accurately. In a typical system, an irradiation beam is emitted from a source, passes through an irradiation-optical system, and enters a Wien filter (“E×B”). Upon passing through the E×B, the irradiation beam passes through an objective-optical system and is incident on an object surface. Such impingement generates an observation beam that returns through the objective-optical system and the E×B in a different direction to a detector via an imaging-optical system. An adjustment-beam source emits an adjustment beam used for adjusting and aligning the position of, e.g., the object surface and/or the Wien's condition of the E×B. The adjustment beam can be off-axis relative to the objective-optical system. For such adjusting and aligning, fiducial marks (situated, e.g., in the plane of the object surface) can be used that are optimized for the CPB-optical system and the off-axis optical system. Desirably, the image formed on the detector when electrical voltage and current are not applied to the E×B is in the same position as the image formed on the detector when electrical voltage and current are applied to the E×B. Also provided are “evaluation charts” for use in such alignments that do not require adjustment of the optical axis of the irradiation-optical system, and from which the kinetic-energy distribution of the emitted adjustment beam is stable.
