EMBEDDED-COMPONENT-TYPE ACTUATOR AND CONTINUOUSLY VARIABLE VALVE DURATION SYSTEM, AND VALVE TRAIN SYSTEM FORMED THEREBY
An embedded-component-type actuator is provided. The actuator includes an output shaft that is rotated, a planetary gear set that forms an overlapping section coaxially with the output shaft, and a motor that is coupled to the overlapping section of the planetary gear set. A sensing controller detects a rotation angle of the output shaft. The output shaft passes an actuator housing and the planetary gear set, the motor, and the sensing controller are arranged in series, thus minimizing a package. Additionally, the actuator is applied as the power source of a CVVD system to improve mountability to a complex engine room due to the space occupancy minimization.

ARRANGEMENT JIG FOR A SIDE TRACK BUFFER, SIDE TRACK BUFFER SYSTEM HAVING AN ARRANGEMENT JIG AND METHOD OF ARRANGING A SIDE TRACK BUFFER USING AN ARRANGEMENT JIG
Provided are an alignment jig, a side track buffer system including the same, and an alignment method using the same. The alignment jig includes a horizontal jig fixed to a bottom plate of a side track buffer to extend in a horizontal direction to a lower portion of the transfer rail, and a vertical jig fixed to the transfer rail to extend downward in a vertical direction so as to be adjacent to a top surface in the horizontal direction. A separation distance between an intersection point of the vertical jig and the horizontal jig and a central portion of the bottom plate is detected as a buffer separation distance, and a buffer frame is horizontally moved automatically or manually to allow the buffer separation distance to match a reference separation distance, so that the side track buffer is installed in an accurate position.

METHOD FOR CORRECTING POINTING ERRORS OF BIAXIAL ROTATION SYSTEM BASED ON SPHERICAL CAP FUNCTION
The invention discloses a method for correcting the pointing errors of a biaxial rotation system based on the spherical cap function, comprising: error collection: selecting stars or radio sources distributed evenly in a star catalogue for tracking and observation to obtain the theoretical position and measurement position of the stars, and subtracting the measurement positions and the theoretical positions to obtain the error distribution; error model fitting: selecting a suitable orthogonal spherical cap function for the obtained error distribution and performing fitting to calculate an error fitting coefficient, the orthogonal spherical cap function model comprising a hemispheric harmonic function HSH, a Zernike spherical cap function ZSF, and a longitudinal spherical cap function LSF; and error control and compensation: putting the error model and the related fitting coefficient into a pointing control system for compensation. In the present method for correcting the pointing errors of a biaxial rotation system based on a spherical cap function, the model has strong stability and is not easily affected by measurement noise; there is no need to determine the form of the model on the bases of the frame form of the telescope, and the correction accuracy is high.
