Abstract: A droplet generator includes a steering system, a reservoir, a nozzle, a first heater, a second heater and a third heater. The steering system is used for controlling a position of droplet release of the droplet generator. The reservoir is held on the steering system for storing tin. The nozzle is connected with the reservoir for generating tin droplets, wherein the nozzle comprises at least a first zone, a second zone and a third zone connected in sequence. The first heater surrounds a peripheral surface of the nozzle in the first zone. The second heater surrounds a peripheral surface of the nozzle in the second zone. The third heater surrounds a peripheral surface of the nozzle in the third zone, wherein the heating of the first heater, the second heater and the third heater are separately controlled.

Abstract: A case assembly includes a first case, a second case, a moving mechanism and a block. The first case has an inner surface and a groove located at the inner surface. The second case includes a main part disposed on the first case and a fixing part disposed on the main part. The moving mechanism is pivoted to the inner surface. The block is pivoted to another end of the moving mechanism. The block is slidable between a fixed position and a detached position. When the block is located at the fixed position, the block restricts the fixing part so as to assemble the second case and the first case together. When the moving mechanism drives the block to the detached position, the fixing part is not restricted by the block, and the moving mechanism forces a part of the second case to separate from the first case.

Abstract: A signal transmission device is provided. The signal transmission device comprises a linked unit, a switch button, a data connector and a lock fastener. The linked unit includes a first shaft, a second shaft, a first elastomer and a second elastomer. The switch button is attached/disposed on the linked unit. The data connector rotates and expands according to the first shaft and the first elastomer. The lock fastener rotates and moves according to the second shaft and the second elastomer.
