Abstract: A planar winding transformer includes a magnetic core set and a multilayer circuit board. The magnetic core set includes two magnetic cores and two magnetic columns. The two magnetic cores are parallel to each other. The multilayer circuit board is disposed between two magnetic cores, and two magnetic columns penetrate through the multilayer circuit board. The multilayer circuit board includes two low voltage winding layers and one high voltage winding layer. Two low voltage winding layers are connected to each other in parallel, and the high voltage winding layer is disposed between two low voltage winding layers. When the high voltage winding layer receives a polarity current, at least one of the low voltage winding layers generates a corresponding induced current. Two magnetic cores and two magnetic columns form a closed path for magnetic flux.

Abstract: An automatically detecting system with microscope includes a platform and a gripper. The platform has a carrying area, a fixed block, a movable block, and an elastic member. The carrying area is formed at the platform, the fixed block and the movable block are configured at opposite sides of the carrying area, and the elastic member is connected to the movable block. The gripper pushes the movable block through an inclined plane of the movable block when moving a slide to the carrying area. When the gripper puts the slide on the carrying area, the movable block and the fixed block hold the slide with the elastic restoring force of the elastic member, and the gripper closes and moves on the upper surface of the slide to flatten the slide. Therefore, the slide can be set on the platform stably and flatly to obtain the focal length precisely and rapidly.

Abstract: A liquid amount control device includes a position detector, a pump, a driver and a controller. The pump is connected with a first tip and configured to suck up the liquid out of the test tube. The driver is connected with the pump and configured to drive the pump to move. The controller is configured to: (1) control the driver to drive a first suction end of the first tip to enter a detection region of the position detector to obtain an end height position of the first suction end; (2) control the driver to drive the first suction end of the first tip to enter the liquid by a first entering depth according to the end height position; and (3) control the pump to suck up the liquid in the test tube through the first tip.
