  • Publication number: 20210272276
    Abstract: A benign tumor development trend assessment system includes an image outputting device and a server computing device. The image outputting device outputs first/second images captured from the same position in a benign tumor. The server computing device includes an image receiving module, an image pre-processing module, a target extracting module, a feature extracting module and a trend analyzing module. The image receiving module receives the first/second images. The image pre-processing module pre-processes the first/second images to obtain first/second local images. The target extracting module automatically detects and delineates tumor regions from the first/second local images to obtain first/second region of interest (ROI) images. The feature extracting module automatically identifies the first/second ROI images to obtain at least one first/second features. The trend analyzing module analyzes the first/second features to obtain a tumor development trend result.

  • Patent number: 8893574
    Abstract: A ball screw with sectional circulating assemblies comprises an inner circulating block and an outer circulating block. In assembly, the inner circulating block is initially placed between the screw shaft and the nut before the rolling balls and the screw shaft are positioned, thus preventing the rolling balls from dropping out and the interference with the threads of the screw shaft. After the rolling balls and the screw shaft are positioned, the outer circulating block is placed into the nut and engaged with the inner circulating block, and the outer circulating block is fixed to the nut. This method can maintain the tightness of the nut, thus preventing the leakage of noise.

  • Publication number: 20140222201
    Abstract: A directional position control method uses an instructor device and a controller to control motion of a robot, and a directional-control starter is used to actuate a directional control function. The directional-control starter controls the controller to drive the robot to move according to the instructor direction reference by converting the coordinate of the robot into the coordinate of the instructor. The directional position control method allows the movement direction reference of the robot to be defined manually or automatically, so that the robot can be moved based on the instructor direction reference of the instructor, allowing the operator to operate the robot by intuition without too much discretion, consequently reducing difficulty and error in operating the robot. Besides, the operator can control the robot by staying at the location where the instructor is located, without standing close to the robot, therefore, improving safety of operating the robot.

  • Patent number: 8381607
    Abstract: A roller screw includes a long shaft, a screw nut sleeved onto the long shaft, and rollers, a turnaround member and a turnover member set in between the long shaft and the screw nut. The turnaround member enables the rollers to circulate. The turnover member defines a turnover passage extending over the peripheral surface of the long shaft and connected between two load paths in the long shaft and the screw nut to constitute a circulation path. The direction of arrangement of the rollers before entering the turnover passage is different from that after moving out of the turnover passage so that the amount ratio of the rollers that are arranged in two different directions is kept constant for industrial application.

  • Patent number: 8316732
    Abstract: A roller screw structure comprises a nut, a screw and a rolling assembly. The rolling assembly is movably disposed between the nut and the screw and includes at least one rolling cone. The slantwise rolling surface of the rolling cone contacts the spiral groove surfaces of the nut and the screw in a line-to-line manner, and the angle between the rolling surface and the self-rotation axis of the rolling cone is from 0 degree to 6.3 degrees. Thereby, making the distance between the self-rotation axis and the rolling surface of the rolling cone of the rolling assembly different can prevent the occurrence of speed difference caused at different rolling paths of the rolling assembly.

  • Publication number: 20120103115
    Abstract: A nut rotary ball screw with a predetermined pressure structure is disclosed. In the nut rotary ball screw of the present invention, we may rotate the predetermined pressure adjusting device to adjust the magnitude of the predetermined pressure by generating a predetermined pressure between the first inner slot and the outer slot as well as the first rolling pieces and between the second inner slot and the outer slot as well as the first rolling pieces. The present invention can greatly simplify the complicated adjustment process of the predetermined pressure in the prior art and can eliminate the time-consuming grinding step and the steps to disassemble or assemble a bolt. Accordingly, the present may simplify the adjustment process of the predetermined pressure and may lower the production cost.
