A cooling method for multi-axis controller includes a first step of enabling a first temperature sensor and a second temperature sensor to respectively detect the temperature of a first heat source and the temperature of a second heat source and to send the respective detected data to a control unit, and a second step of enabling the control unit to drive a first bi-direction fan to exhaust air if the temperature of the first heat source surpasses a predetermined upper temperature limit or to drive a second bi-directional fan to exhaust air if the temperature of the second heat source surpasses the predetermined upper temperature limit, thereby achieving enhanced cooling efficiency.

An electric gripper system includes a motor driving a gripper mechanism, a sensor, and a controller. The sensor is assembled onto the motor for generating a current position of the gripper mechanism. The controller has a control segment, a transceiver segment, an accessible segment, and a driving segment. The control segment generates a target position according to a relative-position command value of the transceiver segment and an absolute cumulative position of the accessible segment. The control segment generates a driving datum based on a difference between the current position and the target position, and on a rotation rate of the motor. The driving segment uses the driving datum to drive the motor to move the gripper mechanism. With calculation among the relative-position command value, the absolute cumulative position, and the current position, the motor is prevented from accumulating positional deviation.

The present invention provides a method of producing hollow silica particles. First, an amine-ketimine compound is mixed with water to obtain a hydrophobic core dispersion, and then an organic siloxane compound and/or a coupling reagent is added into the hydrophobic core dispersion to form a core-shell silica dispersion. Then, the core-shell silica precipitate is separated from the core-shell silica dispersion, and then it is further dispersed and washed by a low carbon alcohol solution. Finally, hollow silica particles in accordance with the present invention are produced. In addition, the present invention also provides hollow silica particles produced by the afore-mentioned method without using any additional surfactant.
