摘要:
A light emitting apparatus comprising a light emitting device (101) disposed on a supporting body (105), and coating layers ((108, 109) that bind a fluorescent substance that absorbs light emitted by the light emitting device (101) and emits light of a different wavelength and secures the fluorescent substance onto the surface of the light emitting device (101). The coating layers (108, 109) are made of an inorganic material including an oxide and a hydroxide, each containing at least one element selected from the group consisting of Si, Al, Ga, Ti, Ge, P, B, Zr, Y, Sn, Pb and alkali earth metals. Also an adhesive layer (110) is made of the same inorganic material as that of the coating layers (108, 109).
摘要:
The present invention provides a numerical control system employing an automatic tuning section for automatically tuning control parameters, such as position deformation parameters, corresponding to the numerical control of the position of a table using a servo loop. In particular, the present invention provides an apparatus for, a method of, compensating for machine deformation and ballscrew errors produced by the play resulting from loose connections between a ballscrew and a moving table engaged thereto. The present invention provides a first and second change slowing means for respectively changing the compensation amounts of the machine deformation and ballscrew deformation error amount stored in a numerical control apparatus. The first and second change slowing means allow the machine deformation and ballscrew deformation error amounts, respectively, to be combined with a position command signal output from the numerical control apparatus to form a compensated control signal in order to control the positioning of the table with high accuracy.

摘要:
An apparatus for and method of automatically tuning control parameters of a servo or spindle drive system controlled by a numerical control unit is disclosed. The numerical control unit employs an automatic tuning device that automatically selects a tuning program and test run program associated with a selected control parameter. The tuning device test runs the servo or spindle according to the test run program selected and changes and controls the status value data measured in accordance with the control parameter selected. The invention also relates to a method of changing a criterion for the feature values of a control parameter, a method of comprehensively determining the feature values where there are a plurality of tuning conditions, and a method of sampling the status value data of the servo or spindle.
