Abstract: A stiffened diaphragm manufacturing method and the manufactured diaphragm using same are provided. The manufacturing method includes the steps of: applying a hot glue layer to a side of a stiffened plate; putting a base layer on the hot glue layer, and then heating and adhering the base layer and the stiffened plate together; and performing a pressing process on the base layer and the stiffened plate to form a diaphragm having a central portion and a surround portion. The stiffened plate is coated uniformly with the hot glue layer and then put on the base layer to undergo heating and adhesion; hence, an oversupply or undersupply of a glue will be unlikely to happen. Furthermore, the manufacturing process is simple and attains high-strength adhesion between the stiffened plate and the base layer.

Abstract: A composite diaphragm is provided to include a base layer and a micro-nanometer ceramic layer disposed on the surface of the base layer. The micro-nanometer ceramic is a structural material that has great stiffness and toughness, such that the composite diaphragm made of micro-nanometer ceramic manifests characteristics of high stiffness, high toughness, and great ductility. Thus, the composite diaphragm allows large deformation at room temperature to achieve high capability of producing high-definition tone.

Abstract: The present invention discloses a bird view system and a compensating method thereof. The system comprises a processing module and an image compensating module. The processing module receives and processes a bird view image generated from concatenating each image captured by each camera in the bird view system. The image compensating module compensates the bird view image. The processing module calculates a first compensation value and a second compensation value according to the difference of image information of overlapping or concatenating regions between an image and its adjacent right-hand or left-hand side images. The compensating module compensates the bird view image according to the first compensation value, the second compensation value and a compensation condition.

Abstract: The present invention pertains to a method of manufacturing a bi-metal screw comprising a sequence of procedures; wherein, the process preparation is for arranging a shank portion and a drilling portion made of different materials; the shank portion has a planar welding surface defined thereon; in particular, the drilling portion includes a conical section with a conical surface defined on the top face thereof. While operating, the conical section is gradually welded to the planar welding surface to form a composite screw, so as to smooth the air away for preventing the interspaces generated within the junction of the two portions and rendering the composite screw not to be slanted aside. Subsequently, an integral bi-metal screw is formed through the processes of precisely cutting and formation, thereby increasing the quality of the screw.
