Abstract: A flow meter includes a meter body and a pressure sensor. The meter body has a liquid impact surface, a sensing surface opposite to the liquid impact surface, and a mounting hole extending from the sensing surface toward the liquid impact surface. The mounting hole is a blind hole. The pressure sensor is mounted in the mounting hole, and has a resistance value that can be measured and that can be changed correspondingly with a change in liquid pressure caused by a change in flow rate. A device for producing an active hydroxyl free radical solution is also disclosed.

Abstract: An improved magnetic component structure, wherein the structure comprises a base and two iron cores, in which the base includes a centrally through winding axle tube and the openings at both the left and right ends of the winding axle tube individually extend out a baffle. Additionally, the two iron cores are caps, in which a core column extends out from the center of the iron core toward the opening of the winding axle tube, and the core column can be inserted to the centrally through part of the winding axle tube. Therefore, the two iron cores can be clip installed between the two sets of pin parts of the base and left and right assembled to the base such that the base combined with the two iron cores can be installed upright on one side having the notch of a drive circuit board in an LED light tube.

Abstract: The locked phase active power current control circuit is composed of a DC source, an electronic switch, a driving transformer, a phase detecting unit, a current intercepting unit and a square wave controller. A DC signal provided by the DC source is converted into a square wave signal by the electronic switch for the driving transformer to operate a load. The electronic switch outputs the square wave signal to the phase detecting unit whereat a phase signal of the square wave is detected and the detected signal is transmitted to the current intercepting unit whereat the detected signal is compared with the current intercepted at the electronic switch, the driving transformer, or the load, and the comparison result is fed back to the square wave controller so as to set the operation frequency of the electronic switch. The essential principle of the present invention is based on the fact that the square wave is in phase with the first harmonic wave.
