A CT detector includes a scintillator module including at least one scintillator configured to be impinged with radiographic energy from a radiographic energy source, at least one indexing pin connected to the scintillator module, and a collimator assembly having at least one comb, wherein the collimator assembly defines a relative position of the at least one comb, and wherein the at least one comb has a plurality of teeth configured to engage the at least one indexing pin.

Self-aligning scintillator-collimator assembly

The present invention is directed to scintillator module for a CT detector as well as an apparatus and method of manufacturing the same. The scintillator module is comprised of a scintillator array having a plurality of scintillators aligned in parallel with respect to one another. A collimator assembly includes a comb having a number of teeth and a plurality of collimator plates positioned proximate to the scintillator array. The scintillator array includes at least one indexing pin extending therefrom. The indexing pin engages the comb and is constructed to improve alignment of the scintillator array relative to the collimator plates.

A heat exchanger using two hydrogen storage alloys, including: a tubular housing member disposed in a horizontal position; a vertical partition plate extending axially within the housing member for partitioning the inside space of the housing member into two, first and second reaction zones in which the first and second alloys are contained, respectively, to form an upper space above each alloy; first and second heat-exchange tubes disposed in the first and second reaction zones, respectively, and arranged so that first and second fluids may be passed therethrough for indirect heat exchange with the first and second alloys, respectively; openings provided in the vertical partition plate at least at positions so that the upper space in the first and second reaction zones are in fluid communication with each other; and a plurality of vertically extending gas passages provided in each of the first and second reaction zones, and each being in fluid communication with the upper space, whereby hydrogen gas released from one of the first and second alloys can efficiently diffuse in the other alloy.
