An integrative device of a leak test and leak reset button for a leak breaker. The part of the test reset button above a case body is divided into two layers. The upper layer is a T layer surface (101) and the lower layer is a R layer surface (102). The test reset button bends in the underside and stands out to form a combine part (104) in the bottom. The combine part is clipped with a chimb combine part (401) of a leak lock to form a linkage. A test circuit simulating the leak current is provided with the protect function of double break nods to turn off. The advantages of the invent is to integrate the test button and reset button into a single device, therefore the structure gets simple and small and can be used in a smaller leak break. A burn accident is avoided by a break nod circuit board in the projection part of a handle when inlet and outlet wires in errors.

The invention discloses an efficient generating shoe capable of generating electricity. The efficient generating shoe comprises at least one cavity formed in the sole of the shoe, an airflow-driven generating device, an energy accumulator connected with the airflow-driven generating device through a control circuit and an air energy accumulator for storing pressure air, wherein the cavities can be compressed and can restore deformation on the dependence of the elasticity of the cavities. Each cavity is provided with a one-way air inlet and a one-way air outlet. All the one-way air inlets gather to form a main one-way air inlet. All the one-way air outlets gather to form a main one-way air outlet. The airflow-driven generating device is provided with an air inlet and an air outlet which are connected with the main one-way air outlet. The air energy accumulator for storing pressure air is arranged between the air inlet and the main one-way air outlet of the airflow-driven generating device. When the shoe gets away from the ground, the air energy accumulator can supply air to the airflow-driven generating device continuously till the pressure of the air inlet and the pressure of the air outlet of the airflow-driven generating device reaches the balance, and the generating efficiency is improved effectively.

A semiconductor structure and a method for forming the same, wherein the forming method includes: providing a substrate with a fin column on the substrate, the fin column includes a bottom region, a channel region located on the bottom region, and a channel region located on the bottom region. A top region on the channel region; a first isolation layer is formed on the substrate, and the first isolation layer covers the bottom region of the fin column; and a sidewall surface of the channel region of the fin column is formed a first gate oxide layer and a second gate oxide layer, the second gate oxide layer is located on the top surface of the first gate oxide layer, and the thicknesses of the first gate oxide layer and the second gate oxide layer are different; A gate structure is formed on the top surface of the first isolation layer, and the gate structure covers the first gate oxide layer and the second gate oxide layer; a second isolation layer is formed on the top surface of the gate structure, and the second An isolation layer covers sidewalls of the top region of the fin post. The formation method can improve the performance of the semiconductor structure.

The invention relates to the technical field of valve control in fluid delivery, in particular to a freeze protection check valve for a liquid delivery pipeline. The freeze protection check valve for the liquid delivery pipeline comprises a valve body, and a valve clack and a hole plugging device which are arranged in the valve body; the valve clack is provided with a plurality of damping holes; the hole plugging device is arranged on the valve clack and is not interfered with the opening and closing of the valve clack; the hole plugging device is matched with the damping holes and can seal the damping holes if necessary. When the check valve is in a low temperature working condition, open damping holes can enable liquid from the check valve to a water tank pipeline to slowly flow through the damping holes to flow back, and the pipeline is prevented from being subjected to frost cracking due to long-term liquid storage; continuous production is required in summer or in busy times, the damping holes are sealed by the hole plugging device and the on / off states of the damping holes in the valve clack are changed through the hole plugging device, so that working efficiency is ensured, different functions of the check valve are realized, and different working condition requirements are met.
