摘要： A heat transfer fluid storage device is provided, including a tank and one or more vertical chambers open at top and bottom and spaced from the top and bottom of the tank to define upper and lower liquid storage areas. Means are provided to extract liquid from either the lower storage area or the upper storage area, or both, deliver the liquid to heat exchanger means and then return the liquid to either the lower or the upper storage area, or both.

摘要： Energy distribution at a section of a laser beam is leveled by causing the laser beam, emitted by a continuous wave Q-switch pulse from a laser oscillator having an acousto-optic Q-switch element, to pass through a mask having a mask pattern. The laser beam having passed the mask is reflected by a pair of reflection mirrors provided on a pair of galvanometers. The reflected laser beam passes through an objective lens and is focused on a processing object. A desired character or sign is marked on the processing object through a scanning with the laser beam focused on the processing object by driving a pair of galvanometers.

摘要： A laser marking system comprises a continuous-wave (CW) pumped Q-switch pulse laser and a laser controller. The Q-switch element switches on and off according to a repetition control signal received from the laser controller. The repetition control signal comprises an emission period in a repetition rate. The CW-pumped Q-switch pulse laser emits the laser beam through the Q-switch element during the emission period. The emission period or duty factor of the repetition control signal is adjusted such that the CW-pumped Q-switch pulse laser emits a pulse laser beam comprising a plurality of emission pulses during the emission period. The pulse laser beam is used to generate a scanning pulse laser beam which is focused on the workpiece to be marked in a desired pattern.
