Abstract: A fabricating method for the self-drilling screw has acts of forming a main section and a secondary section by punching, forming a flat drilling blade with a tapered end at a bottom end of the small diameter portion by punching, and forming a thread portion on an outer surface of the main section and a chip removal thread portion with a spiral chip removal groove on an outer surface of the secondary section by rolling. The self-drilling screw utilizes the flat drilling blade with the tapered end and the chip removal section having chip removal function to reduce the size of the drilling blade. Therefore, the self-drilling screw reduces the size of the punching die, lowers the punching force, lowers both the load of the punching die and the load of the punching machine, and lowers both the die cost and the manufacturing cost.

Abstract: Sea wave energy is converted into electrical or mechanical energy. When a sea wave is pushing up a float, a transporter arm is pushed up inside a sealed box. This pushing up motion converts linear motion of the transporter arm into kinetic energy for a chain belt and an upper sprocket which are moving in a rotational path. When the float is moving down because the sea wave is receding, the transporter arm also comes down. This downward motion converts the linear motion of the transporter arm into rotational motion for the same chain belt and a lower sprocket which are moving in the same direction as the chain belt moves with the upper sprocket.

Abstract: An electric plug includes a casing, two metal contacting blades, a printed circuit board and a cap. The casing has a cavity defined in the casing. The two metal contacting blades are mounted in the casing and extend out from the casing. The printed circuit board is received in the cavity in the casing and has two metal clampers electrically connecting with the printed circuit board. Each clamper has two legs mounted on the printed circuit board and curved toward each other for securely clamping the contacting blade between the two legs and electrically conducting the contacting blade with the printed circuit board. The cap is mounted on the casing for closing the cavity in the casing. The clampers provide a high heat-resistance. The connections between clampers and the contacting blades are firm for providing a well conduction without wire or welding.

A component assembly comprising a functional element and a sheet metal part as well as a method for the attachment of a functional element to the sheet metal part are also claimed.

Abstract: A process for foaming ceramic foams, in which the ceramic foams are produced from a precursor or a mixture of precursors which contain at least one ceramic-forming element and liberates at least one volatile reaction product during an inorganic gelation process. In one embodiment, foaming is based on a precursor containing crystals of the AlCl3(Pri2O) complex. The decomposition of the initial precursor produces polymerizing species dissolved in liquid isopropyl chloride. The solvent and growing AlOxCly(OPri)z species are mixed homogeneously so that the boiling point of the solution is raised above the boiling point of the pure isopropyl chloride. Polymerization takes place in the liquid until a critical polymer size is attained, whereupon a phase separation into polymer rich and solvent rich regions occurs. Since the expelled solvent is suddenly above its boiling point, bubbles start forming instantly.

Abstract: An inflatable product has an air pump device and a pressure releasing valve. The air pump device has a housing and a pumping assembly. The housing has two openings as an inlet opening and an outlet opening. The pumping assembly is mounted in the housing and has a motor and a fan.
