378131000 | With specific motor means | 12 |
20100080359 | X-ray generating method, and x-ray generating apparatus - An energy beam is irradiated onto a rotating anticathode so as to heat a portion irradiated by the energy beam under the condition that a vapor pressure at equilibrium state of the portion is set to 0.1 Torr or more, thereby generating an X-ray. The portion irradiated by the energy beam is kept at the rotating anticathode by a centrifugal force to the portion it a direction outward from a surface of the portion. | 04-01-2010 |
20100322385 | FREQUENCY TUNED ANODE BEARING ASSEMBLY - In one example embodiment, an x-ray tube comprises an anode configured to rotate at an operating frequency, and a bearing assembly configured to rotatably support the anode and tuned to a resonant frequency that is different than the operating frequency. | 12-23-2010 |
20110038459 | X-RAY TUBE BEARING SHAFT AND HUB - In one example, an assembly comprises a hub and a shaft. The hub defines an axis of rotation and includes first and second flanges that at least partly define a substantially cylindrical hub opening. The shaft is connected to the hub and includes a first end and a shaft cavity. The first end is received within the hub opening. The shaft cavity is formed in the first end and includes a bottom having a substantially curved transition area. | 02-17-2011 |
20110135065 | MAGNETIC COUPLER DRIVE FOR X-RAY TUBE ANODE ROTATION - An x-ray tube includes a housing enclosing a vacuum chamber, a cathode positioned within the vacuum chamber configured to emit electrons, and an anode positioned within the vacuum chamber to receive the electrons emitted from the cathode and generate a beam of x-rays from the electrons. The x-ray tube also includes a magnetic coupler drive configured to rotate the anode, with the magnetic coupler drive having an inner rotor frame positioned within the vacuum chamber and an outer rotor frame positioned outside the vacuum chamber and adjacent the inner rotor frame. The magnetic coupler drive also includes an inner rotor magnet mounted to the inner rotor frame and an outer rotor magnet mounted to the outer rotor frame. The inner and outer rotor magnets interact to generate a magnetic field that transfers torque from the outer rotor to the inner rotor, thereby causing the inner rotor to rotate the anode. | 06-09-2011 |
20110280375 | AMPLIFYING OPTICAL CAVITY OF THE FABRY-PEROT TYPE - The disclosure relates to an amplifying optical cavity of the Fabry-Perot type that can be used in combination with a high-rate picosecond pumped laser for generating monochromatic X-rays. The disclosure relates to an amplifying optical cavity of the Fabry-Perot type that can be used for obtaining a strongly focused pumped laser beam having a high stability at the average power P | 11-17-2011 |
20120076277 | ASYNCHRONOUS MOTOR WITH FEATURES CREATING MAGNETIC FIELD DISTURBANCE - A component for introducing disturbances into the magnetic field of an asynchronous motor by altering a reluctance of the motor is disclosed. An asynchronous motor is provided that includes a stator having a plurality of windings that is configured to generate a rotating magnetic field when a current is provided to the plurality of windings. The asynchronous motor also includes a rotor positioned within the stator configured to rotate relative thereto responsive to the rotating magnetic field and a component separate from the stator and the rotor that is positioned within the rotating magnetic field, with the component being configured to alter a magnetic reluctance of the rotor so as create a disturbance in the rotating magnetic field. | 03-29-2012 |
20120257722 | X-RAY EMITTER - An x-ray emitter has a rotating envelope x-ray tube that is rotatably mounted on a shaft in an emitter housing filled with a cooling and insulating agent, and a drive apparatus coupled to the rotating envelope x-ray tube by the shaft. The emitter housing is hermetically sealed and the drive apparatus includes a predetermined number of permanent magnets as well as electromagnets corresponding thereto. The permanent magnets are arranged within the emitter housing and alternate annularly around the shaft in terms of their polarity. The electromagnets are arranged on an exterior of the emitter housing and can be controlled by a control and regulating unit to produce a rotating alternating field. The x-ray emitter is suited to high rotational speeds and/or to high pressures of the cooling and insulating agent in the emitter housing. | 10-11-2012 |
20130077757 | X-RAY APPARATUS - An x-ray apparatus includes an x-ray emitter having an x-ray tube, a rotary anode disposed in the x-ray tube, and a drive for the rotary anode. The drive includes a reluctance motor having a stator disposed outside the x-ray tube and a rotor disposed inside the x-ray tube. The rotor is mechanically connected to the rotary anode. | 03-28-2013 |
