When the dragging part is released by the positioning structure, a manipulator can manipulate the dragging part to make the sitting portion and the back portion relatively pivot to switch the child safety seat between a lying status and a sitting status. Thereby, the manipulator can conveniently and quickly adjust the child safety seat through the adjustment mechanism.

A dispensing pump includes a housing extending along a longitudinal axis and configured to be inserted in a bottle. The housing defines a dosing chamber and includes a venting hole. A retaining ring is fastened to the housing and inserted therein. A hollow stem is associated to a piston and inserted in a hole of the retaining ring leaving a passage. The hollow stem and piston are movable between a lowered position and a raised position corresponding to different volumes of the dosing chamber. A venting path includes at least the passage between the hollow stem and the retaining ring and the venting hole. Through the venting path a volume of air enters the bottle through the venting hole during the pump actuation to replace liquid pumped out from the bottle by the pump. A venting valve is interposed between the hollow stem and retaining ring, along the venting path.

Provided are a wafer having a thermal circuit and power supplier therefor, which enable the wafer to heat or cool itself without using any additional heating or cooling system. The wafer includes the thermal circuit that is installed on one side of the wafer to be capable of self-heating or self-cooling the wafer in order to perform a heating process or cooling process on a semiconductor device formed on the surface of the wafer and exchanges heat with the semiconductor device. Thus, a temperature of a semiconductor device can be precisely controlled, and heating and cooling energies are greatly reduced through a direct heat exchange method, thus attaining high efficiency. Since the thermal circuit is directly installed in the wafer, it is structurally simple and the costs of production and installation can be notably reduced. Also, the present invention is very advantageous for optimization, miniaturization, simplification, and environmentally friendly production of a wafer heating / cooling system. Furthermore, a temperature measuring circuit is installed on a reverse surface of the wafer so that the amount of energy that acts on an actual semiconductor device or actual temperature can be accurately measured in real time.

A self-draining vacuum breaker includes a tubular first valve, an internally-stepped tubular second valve, a circular diaphragm, a movable stopper, and a spring. The first valve includes an inlet formed at an end and thereof, and a coupling end formed at the other end thereof and having an external thread. The second valve includes a coupling portion formed at an end thereof and having a thread hole, and an outlet formed at the other end thereof, and a recess formed in the thread hole for jamming said circular diaphragm and having an outlet hole. A stepped portion is formed between the thread hole and the outlet hole, having a plurality of vent holes running therethrough for communicating with outside. Therefore, when the self-draining vacuum breaker is connected between an outfall and a hose, the air can be brought into the hose to eliminate the vacuum.
