A tattoo needle tip () with a capillary ink reservoir () and combined device thereof are provided. The tattoo needle tip () includes a needle tip body (). A needle passage () is defined inside the needle tip body () for placing a tattoo needle (). The needle opening () is communicated with the needle passage (). A capillary disposed ink reservoir () directly connected to the needle opening () whereby can directly feed ink to the sharp end of the tattoo needle ().

Tattoo needle tip with capillary ink reservoir and combined device thereof

A vehicle position detecting method comprises: continuously detecting a detection region and generating a sensing signal by a sensor (S); continuously determining whether a sudden change exists in the sensing signal, and starting timing when the sensing signal suddenly changes (S); terminating timing after a preset time, if the sensing signal received at an end of timing does not restore to the sensing signal prior to the sudden change, confirming a vehicle is or is not in the detection region (S); the sudden change is defined as a variation of the sensing signal per unit time exceeding a preset range. A vehicle position detecting system is also provided.

An air-tight door system and a control method therefor. The air-tight door comprises a first door (M), a second door (M), a first door detection module (SSP), a second door detection module (SSP) and a controller (K). The air-tight door control method comprises: the first and second detection modules (SSPSSP) detect whether the first door (M) and the second door (M) are completely closed; and the controller (K) controls opening and closing of the first door (M) and the second door (M) according to whether the first and second doors (MM) are completely closed. The air-tight door system and the control method therefor ensure that at least one door is in the closed state at any time, thereby further improving air-tightness and device safety.

Air-tight door system and air-tight door control method

An air dome foundation comprises multiple foundation modules (). The multiple foundation modules () are used to be placed on the ground end to end. The foundation modules () comprise straight structure and L-shaped structure. The foundation is low in construction cost, short in construction period and suitable for always moving or the situation in which original ground surface can not be modified or damaged.
