摘要： An imaging tube coolant volume control system (14) for an imaging tube (18) includes a compensation tank (80) that is configured to fluidically couple an imaging tube cooling circuit (11). The compensation tank (80) includes a cooling fluid (17) and a compensation-dividing member (100). The member (100) is adjustable in response to the change in volume of the cooling fluid (17). An overflow vessel (82) is fluidically coupled to the compensation tank (80). A compensation valve (86) is coupled between the compensation tank (80) and the overflow vessel (82) and allows flow of the cooling fluid between the compensation tank (80) and the overflow vessel (82) when pressure of the cooling fluid (17) is greater than or equal to a first predetermined pressure level.

摘要： A fluorescent X-ray emitting source has an unfocused, omni-directionally radiating electron source and an anode target for the generation of X-ray bremsstrahlung, which releases mono-energetic X-rays in a fluorescent target. The electron source and the fluorescent target are arranged in a vacuum housing with an X-ray exit window. The housing has an interior wall surface forming the anode target and the fluorescent target is aligned with the X-ray exit window.

摘要： In a computerized tomographic apparatus for radiographic apparatus it has been proposed to orbit a source of X-radiation through several revolutions of the body of the patient. It is desirable to provide cooling to remove generated heat from the X-ray source, this being usually achieved by a cooling fluid such as oil. It is now proposed to provide a closed circuit cooling arrangement, for the source, comprising a circulatory oil path mounted to share in the orbit of the source without external fluid connections. To assist in cooling, the circuit is provided with a radiator and arranged such that, during pauses in the orbit, the radiator is brought to rest in a forced draught from a non-orbiting cooling fan.

摘要： An X-ray tube anode consists of a difficultly meltable plate which carries a layer of black substance outside of the focal point path, specifically upon its under surface. The invention is particularly characterized in that the black substance of the layer consists of a heating product of a mixture which includes titanium dioxide and additions of at least one other oxide which melts with difficulty.

摘要： A single-axis sun sensor consists of a cylinder of an insulating material on which at least one pair of detectors is deposited on a circumference of the cylinder. At any time only one-half of the cylinder is illuminated so that the total resistance of the two detectors is a constant. Due to the round surface on which the detectors are deposited, the sensor exhibits a linear wide angle of + OR - 50* to within an accuracy of about 2%. By depositing several pairs of detectors on adjacent circumferences sufficient redundancy is realized to provide high reliability. A two-axis sensor is provided by depositing detectors on the surface of a sphere along at least two orthogonal great circles thereof.
摘要翻译：单轴太阳传感器由绝缘材料的圆柱体组成，其上至少一对检测器沉积在圆柱体的圆周上。在任何时候只有圆筒的一半被照亮，使得两个检测器的总电阻是恒定的。由于检测器沉积的圆形表面，传感器呈现±50°的线性广角，精度约为2％。通过在相邻的周围放置几对检测器，实现了足够的冗余以提供高可靠性。通过沿着至少两个正交的大圆在球体的表面上沉积检测器来提供双轴传感器。

摘要： An image sensor array of photodetector elements, with two phototransistors at each element. Each phototransistor has emitter, base, and collector regions, with PN junctions between the regions serving as photodetectors which integrate incident light flux. The inherent capacitance of the emitter-base junction of one phototransistor is substantially greater than the inherent capacitance of the other junctions, to provide capacitance for charge storage during the period between incident light and sampling. The emitter-base junction of the second phototransistor serves as a switch when the element is sampled, to provide an electrical output representative of the integrated light. The video output may be derived from the collector regions or from either of the emitter regions.
