摘要： A magnetic resonance imaging system includes an MR signal reception apparatus comprising a receiving multi-coil and a switchover member. The receiving multi-coil receives MR signals and is composed of a plurality of element coils. The switchover member is configured to switch reception states of the MR signals received by the plurality of element coils in response to imaging conditions. The switchover member connects output paths of the MR signals from the plurality of element coils to a receiver, to reception channels in the receiver in response to the imaging conditions. The reception channels is less in number than the element coils. The imaging conditions are for example directed to parallel MR imaging.

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.

摘要： A valve accommodating hole (11), and each of a supply port (20), discharge ports (21 and 22), and output ports (23 and 24) connected to the valve accommodating hole are formed in a valve casing (15), and a valve shaft (12) is attached to the valve accommodating hole (11) so as to be reciprocable in the axial direction. 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.
