The present invention is related to a calibration method for parameters of a power amplifier, wherein the power amplifier has N parameters each having a preset range of standard power output value. The method comprises: step 1: manually calibrate parameter values of N1 parameters among the N parameters to obtain calibrated parameter values of the N1 parameters; step 2: input the calibrated parameter values of the N1 parameters into an Al background process program to calculate and derive calculated parameter values of remaining N2 parameters by the Al background process program, wherein N2 = N - N1; and step 3: install the calibrated parameter values of the N parameters in the power amplifier to finish calibration of the parameters of the amplifier.

A hazardous drug liquid-gas exchange device includes a syringe, a first connector, a second connector and a pressure balancing device. During the procedure of adding medicine, the collecting portion collects toxic gases so that the atmospheric pressure inside the drug bottle or soft bag maintains pressure balance with the external atmospheric pressure, and also prevents a small amount of harmful drugs inside the drug bottle or soft bag from passing through the second connector in gas form or by evaporation. During the procedure of taking medicine, the collecting portion collects and provides clean air, so that the air pressure inside the drug bottle or soft bag maintains a pressure balance with the external air pressure, and hazardous medicines can be easily taken out from the inside of the drug bottle or soft bag. Hazardous drugs will be blocked by the hydrophobic breathable membrane.

Provided is an explosion-proof water tank device, including a base, a circuit control unit, a water tank body, and an explosion-proof shield; wherein the circuit control unit and the water tank body are installed on the base. A water pump installed inside the water tank body is connected to an electrical conduit and a water outlet pipe, both extending outside the water tank body. The electrical conduit is connected to the circuit control unit, and the water outlet pipe is connected to the water outlet of the base. The explosion-proof shield is combined with the base to completely enclose the circuit control unit, the water tank body, the electrical conduit, and the water outlet pipe. Accordingly, the present invention can prevent explosions caused by sparks that may be generated during the operation of the circuit control unit when used in highly hazardous environments where open flames are strictly prohibited.

A direction control apparatus is provided. The direction control apparatus includes an input unit, and a magnetic sensing unit. The input unit includes an operation member, a magnetic member, an elastic member, and a base. The elastic member is an elastic structure. The magnetic sensing unit includes a magnetic sensor, and a magnetic signal processing device. The magnetic sensor is a device for sensing a distribution of a magnetic field, and the magnetic signal processing device is an electronic calculating device. The elastic member is provided for restricting the operation member at either a first status position or a second status position. When at the first status position, the operation member is positioned at balanced position where the elastic member achieves an elastic balance.
