20100071882 | NATURAL MICROTUBULE ENCAPSULATED PHASE-CHANGE MATERIALS AND PREPARATION THEREOF - Microtubule encapsulated microcapsules of a phase-change material and preparation thereof are provided. The microcapsules of a phase-change material consist of a phase-change material, truncated microtubules, and a polymer. The truncated microtubules are formed by truncating hollow tubular natural fibers into fiber segments with a length of 0.1 mm-5 cm. The diameter of the hollow tubular natural fiber is 0.1-1000 μm. The phase-change material is encapsulated in the truncated microtubules and the truncated microtubules are covered with the polymer. The microtubules have high energy storage density due to high hollowness, and can transfer energy stably due to the closed structure, transfer heat rapidly due to the very fine micro-tubular structures, and may be used for a long term in view of the heat and chemical stability. | 03-25-2010 |
20100285313 | MICROENCAPSULATED FIRE RETARDANTS AND THE USES THEREOF - The present invention pertains to a microencapsulated fire retardant and the uses thereof. The inventive micro-encapsulated fire retardant comprises a core containing a fire retardant and a shell of a natural microtubule, wherein the core is encapsulated by the shell. The microencapsulated fire retardant of the present invention can be composited into a certain polymeric substrate by a mixing method so as to form into a corresponding, fire-retardant polymeric composite material. | 11-11-2010 |
20120148013 | SELF ADJUSTING BEARING USED ON CT GANTRY - A self adjusting bearing for use on a CT gantry is provided. The self adjusting bearing is configured to be mounted on a main frame of the CT gantry and is configured to support a rotating base of the CT gantry wherein the self adjusting bearing includes a roller, a first component, and a second component, the roller is configured to support the rotating base and is rotatably mounted on the first component, the second component is configured to be mounted on the main frame, and the first component and the second component are configured to rotatably engage each other such that they can rotate relative to each other during the mounting of the self adjusting bearing. | 06-14-2012 |
20120155607 | BELT-TYPE TABLE AND CT APPARATUS AND A METHOD FOR OBTAINING CALIBRATION DATA FOR A CT APPARATUS - A belt table is provided. The belt table includes a cradle, and a movement driver set configured to drive the cradle to move, wherein the cradle and the movement driver set are configured to cause at least one of low attenuation and nearly zero attenuation to X-rays along a scan plane. | 06-21-2012 |
20120243661 | DATA ACQUIRED SYSTEM AND CT APPARATUS USING THE SAME - A data acquired system is provided. The data acquired system includes a main structure with a cavity formed therein, the cavity having a bottom for mounting a circuit board with electrical components thereto, a fan assembly disposed on the main structure, and an airflow guide disposed within the cavity and configured to guide airflow from the fan assembly for heat dissipation of the electrical components, the airflow guide positioned at a distance above the electrical components to form a gap between the airflow guide and the electrical components, wherein a sidewall of the cavity is provided with an air vent corresponding to the gap such that the airflow passes through the gap and is discharged from the air vent. | 09-27-2012 |
20140003372 | ACTIVATING A MOBILE TERMINAL FROM MOBILE NETWORK SIDE | 01-02-2014 |
20140146939 | X-RAY DETECTOR, COLLIMATOR, CT APPARATUS AND METHOD FOR THE SAME - An X-ray detector, a collimator, a CT apparatus and a method thereof are provided. The X-ray detector comprises a plurality of detector modules which are arranged in an array along a slice direction and a signal channel direction being orthogonal to each other, the array at least comprising a left detection area, a central detection area and a right detection area that are contiguous in the signal channel direction, wherein, in the slice direction, coverage of the left detection area and coverage of the right detection area are complementary and sum of these two coverages is equal to coverage of the central detection area. The collimator comprises a pair of moving shield plates and a fixing shield plate, wherein shape of a window in the fixing shield plate is the same as shape of the array. The CT apparatus comprises the X-ray detector and the collimator. | 05-29-2014 |
20140146948 | CT COLLIMATOR AND CT SYSTEM INCLUDING THE CT COLLIMATOR - A CT collimator comprising a rotating slot part on a rotation shaft and having a plurality of blades, each blade has a slot of a different width and a radiation beam entering the collimator can only pass via a slot in one of the blades, each edge of each blade slot along a longitudinal direction has a convex curved surface structure, and in a vertical plane along a longitudinal direction, two side edges of the slot are curved, and each blade is arranged to be eccentric to the center of the rotation shaft. A CT system using the CT collimator, the detection area of the radiation rays projected to the radiation detector via the CT collimator can be maintained unchanged by adjusting the rotation angle of the blade, under the circumstance where the focus of the radiation source shifts during a CT scan. | 05-29-2014 |
20140208509 | CRADLE DRIVE MECHANISM, A TABLE, AND A PATIENT IMAGING AND CARRYING APPARATUS - A cradle drive mechanism, a table and a patient imaging and carrying apparatus are provided. The cradle drive mechanism includes: a first portion, which is arranged on a main base and has a belt drive structure, wherein the belt drive structure is used to connect a cradle and drive the cradle to make a reciprocating motion; a second portion, which is arranged on a secondary base and has a secondary supporting and rotating member, wherein the second portion and the first portion form a gap therebetween, and the secondary supporting and rotating member is used to support the cradle; and two guiding and rotating members, which are arranged on the second portion and/or the first portion for guiding the cradle to move linearly. The present application can simplify the structure by adoption of the belt drive structure. Further, the gap between the second portion and the first portion does not attenuate the X-ray additionally, so the dose of the X-ray emitted can be decreased. | 07-31-2014 |
