Abstract: This disclosure relates to a film removal apparatus that is suitable for uncovering a film of a semiconductor substrate and includes a carrier, an uncovering mechanism and a lifting mechanism. The carrier supports the semiconductor substrate. The uncovering mechanism includes a slider, a guider and a roller. The slider is slidably disposed on the carrier. The guider is fixed to the slider. The roller is rotatably disposed on the slider and arranged beside the guider. The uncovering mechanism is to uncover the film from the semiconductor substrate. The lifting mechanism selectively separates the semiconductor substrate away from the carrier.

Abstract: A feeding apparatus is provided. The feeding apparatus includes an apparatus body, a container, an elevatable platform, and a pulling mechanism. The container is disposed in the apparatus body, wherein the container has a carrier unit, and the carrier unit is detachably connected to the container. The elevatable platform is disposed on the apparatus body, wherein the elevatable platform is adapted to be moved between the first height and the second height. The pulling mechanism is disposed on the elevatable platform, wherein the pulling mechanism is adapted to be moved relative to the container.

Abstract: A method, apparatus and device for correcting a vascular pressure difference are disclosed. An intracavity imaging technology is used to acquire images in a main branch blood vessel. A plurality of blood vessel cross sections are obtained using the images, and an area of a cutting plane of a side branch blood vessel is directly calculated by using the blood vessel cross sections. The blood vessel difference is then corrected by using the cutting area.

Abstract: A blood vessel pressure difference correction method includes: obtaining a plurality of blood vessel cross sections between a first end point and a second end point along a main axis of a first blood vessel by taking a proximal demarcation point of the first blood vessel and a second blood vessel as the second end point, and taking a carina as the first end point; forming contour lines by the blood vessel cross sections on a first blood vessel wall and a second blood vessel wall; enclosing, by the contour lines formed by the blood vessel cross sections on the first blood vessel wall, a plurality of first blood convex surfaces; enclosing, by the contour lines formed by the blood vessel cross sections on the second blood vessel wall, a plurality of second blood vessel convex surfaces; intersecting, by the first blood convex surfaces and the second blood vessel convex surfaces, to form a plurality of intersection lines; fitting the plurality of intersection lines into an intersection plane; calculating an area o
