Aimed at the frequent accidents of conveyor belt and the the lower level of belt fracture protection in coal mine, this paper introduces a novel device equipment, the Eectro-hydraulic type Blt Cpture Dvice (Eh-BCD) to achieve safe and reliable working of steel cord conveyor belt. Firstly, after analysed the typical capture device existing on the market and researched the mechanical properties of the instant belt, an electro-hydraulic control type capture device solution was put forward, its work principle and main modules were introduced also. Secondly, main parts force of capture device calculated using Newtonian mechanics, designed and calculated the mechanical structure of the device, and determined key parameters such as installation space. Finally, after kinematic model built and analysed, device response time parameters the electro-hydraulic controlling capture was estimated.

In this study, the time response behavior of low-temperature polycrystalline silicon (LTPS) thin-film transistors (TFTs) to x-ray irradiation pulses with different frequencies is analyzed. The formulas for the time response of excited and recovery behaviors are proposed for possible use in circuit performance enhancement in real x-ray irradiation situations. The predicted and measured results fit fairly well, which is important in the development of x-ray image sensors using LTPS TFTs.
