Abstract: A silicon carbide crystal includes a seed layer, a bulk layer and a stress buffering structure formed between the seed layer and the bulk layer. The seed layer, the bulk layer and the stress buffering structure are each formed with a dopant that cycles between high and low dopant concentration. The stress buffering structure includes a plurality of stacked buffer layers and a transition layer over the buffer layers. The buffer layer closest to the seed layer has the same variation trend of the dopant concentration as the buffer layer closest to the transition layer, and the dopant concentration of the transition layer is equal to the dopant concentration of the seed layer.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: An image detecting module includes a socket, a circuit board, an image sensor, an elastic element, a filter and a holder. The socket comprises an inner circumference wall along a main axis for defining an inner space and a platform that extended from the inner circumference wall. Pluralities of mounting holes are provided on the holder and pluralities of protrusions are provided on the socket; thus the elastic element and the filter could be fixed between the platform and the holder by fitting the protrusions into the mounting holes.

Abstract: The present invention provides a method for fabricating an indium(In)-111 radioactive isotope. A target of cadmium(Cd)-112 is processed through steps of dissolving with heat, absorbing, washing, desorbing and drying for obtaining the In-111 radioactive isotope. Thus, chemical separation is coordinated with the target for fabricating the In-111 radioactive isotope with high efficiency and low cost for production procedure.

Abstract: A lens module of an imaging device includes a lens-barrel plate, a shutter plate and at least one elastic device. The lens-barrel plate includes at least one guide post, which is vertically arranged on the surface of the lens-barrel plate. The shutter plate includes at least one groove, which facilitates movement of the guide post in the groove. Each elastic device corresponds to an associated guide post and groove. Accordingly, the elastic device is compressed when external force is exerted on the lens-barrel plate and the shutter plate, and the elastic device recovers to separate the shutter plate from the lens-barrel plate when the external force is removed.
