摘要:
A lamp changing module for totally enclosing a lamp when the module is withdrawn from a support such as an illuminator cabinet, and permitting exposure of the lamp when properly installed and connected to the support. A potentially explosive lamp is thereby contained within the module when it is removed so that even if it explodes it will not harm nearby personnel. It also protects personnel from burn hazards associated with lamp changing.
摘要:
This invention concerns an electron beam generating system for high beam voltages in which the insulation between a grounded casing and the high-voltage electrodes is achieved by an insulating body surrounding the high-voltage electrodes with a small distance, so that the dimensions of the system are considerably smaller than with arrangements in which the insulation is primarily achieved by providing sufficient vacuum space about the high-voltage electrodes. The invention is further concerned with an automatically actuable replacement device for cathode holders, said replacement device being adapted to be controlled by monitoring means for at least one beam parameter so that the cathode holder under operation will be automatically replaced by a fresh cathode holder and cathode when the magnitude of the sensed beam parameter falls outside a predetermined range.

An anode target comprises: a plurality of target structures, used for receiving an electron beam emitted by a cathode to generate a ray, the plurality of target structures being of three-dimensional structures having bevels; a copper cooling body, used for bearing the target structures and comprising an oxygen-free copper cooling body; a cooling oil tube, used for cooling the anode target; and a shielding layer, used for achieving a shielding effect and comprising a tungsten shielding layer. The anode target, the ray light source, the computed tomography scanning device, and the imaging method in the present application are able to enable all target spots on the anode target to be distributed on a straight line, imaging quality of a ray system is improved, and complexity of an imaging system is reduced.

For coupling a halogen incandescent lamp to a plastic lamp base in correct positional relationship, a sheet-metal lamp holder is rigidly engaged with a hermetic end seal of the lamp, and a sheet-metal sleeve is anchored in the lamp base. The sleeve has several connecting fingers extending therefrom for somewhat loose engagement in openings in the lamp holder. The loose engagement of the sleeve fingers in the lamp holder openings permit adjustment of the positions of the lamp and the lamp base, which are secured respectively to the lamp holder and to the lamp base, with respect to each other. The sleeve fingers are welded to the lamp holder following the adjustment of the positional relationship between the lamp and the lamp holder.
摘要:
An irradiation device is provided having a housing having an interior chamber and an infrared emitter arranged therein. The infrared emitter has an emitter tube made of high silica content glass having a round cross section and a defined outer diameter. Electrical connection elements are made of a metallic material and led out from the emitter tube through a seal. In order to provide the emitter with a long service life and potentially higher output, which is also suitable for being enclosed by a seal that separates the regions of different media, temperatures, or pressures, the emitter tube end also has a round cross section and the defined outer diameter. Between the electrical connection element and the emitter tube there is a seal containing at least one transition glass, which has a thermal expansion coefficient lying between that of the metallic material and that of the high silica content glass.

摘要:
A device for reconditioning a neutron tube, comprising on the one hand invariant elements and on the other hand sensitive elements which are subject to wear and gaseous elements which are consumable and which are introduced by way of reservoirs. In accordance with the invention the sensitive elements, for example target (6) and gas reservoirs (7, 8) are collected in the same part (1') of the tube, which part is separable from the other part (1) by means of a tight connection system (12, 12', 13, 14 and 15) in order to make the replacements necessary for reconditioning.
