The cooler also includes a tube cage comprising a plurality of tubes, each having a first end and a second end. The cooler further includes a plurality of platen tubes located radially inwardly from the tube cage. The cooler yet further includes a pipe fluidly coupling the second end of the plurality of tubes with an inlet of the plurality of platen tubes. The cooler also includes an outlet pipe fluidly coupling an outlet of the plurality of platen tubes with a steam usage structure. The cooler further includes an inlet pipe fluidly coupling the steam usage structure to the first end of the plurality of tubes of the tube cage.

Abstract: The invention provides an enhanced method and system for machining an array of components. A holding mechanism is provided for holding an array of components in a machining process. The holding mechanism comprises: a rigid base plate and at least one support for holding a raw material while machining, one end of each support being coupled to the rigid base plate. The holding mechanism is further provided with a secure plate movably coupled to the rigid base plate. The secure plate is provided with one or more holding parts such as double-sided tape or guiding pins for holding the raw material. The secure plate can be elevated to hold the raw material during a machining operation such as peripheral machining.

Abstract: A volume change absorber simple in construction and wide in application range, an X-ray generator having such a volume change absorber, and an X-ray imaging apparatus having such an X-ray generator, are to be provided. The volume change absorber includes a rigid pipe-like member capable of being mounted in an airtight manner through a wall of a vessel into which liquid is sealed and a flexible tube having one end portion mounted so as to cover in an airtight manner an end portion of the portion of the pipe-like member which portion lies inside the vessel and also having an opposite end portion which is sealed in a crushed state.

Abstract: An embodiment provides a patient positioning system for an imaging device. The patient positioning system comprises a table assembly for engaging and supporting a patient, at least one single cross bar assembly coupled to the table assembly and a belt drive assembly coupled to the single cross bar assembly, the belt drive assembly being configured to drive the single cross bar assembly. Another embodiment provides a patient positioning system comprising a table assembly and at least two multiple cross bar assemblies coupled to the table assembly. The table assembly is configured to be displaced to multiple positions along a vertical axis. The multiple cross bar assembly comprises multiple pair of cross bars coupled to one another by a pivot. The patient positioning system can further comprise a screw drive assembly coupled to the multiple cross bar assembly for driving the multiple cross bar assembly.

Abstract: A positioning system for positioning a patient support in an imaging device is disclosed herein. The positioning system includes a fine positioning subsystem coupled to the patient support and adapted to position the patient support with fine precision along the X-axis; and a coarse positioning subsystem coupled to the fine positioning subsystem and adapted to position the patient support with coarse precision along the X-axis. In an embodiment, the fine positioning subsystem and the coarse positioning subsystem are a dual-stage drive positioning system, with the first drive including a screw mechanism and the second drive including a prime mover. In an embodiment, a programmer is provided for configuring the fine positioning subsystem to align the patient support based on a velocity profile.
