Abstract: Semiconductor devices and methods of manufacture are provided wherein a metallization layer is located over a substrate, and a power grid line is located within the metallization layer. A signal pad is located within the metallization layer and the signal pad is surrounded by the power grid line. A signal external connection is electrically connected to the signal pad.

Abstract: A dual pass band filter element includes: a substrate, and a bandpass filtering structure and an anti-reflection structure formed on two opposite surfaces of the substrate. The bandpass filtering structure includes a plurality of first material layers and a plurality of second material layers with a refractive index higher than the respective first material layers, wherein the first and second material layers are stacked alternately along the normal of the substrate; the dual pass band filter element has a first pass band and a second pass band that does not overlap with the first pass band in a band of 400 nm to 1800 nm. In this way, two different bands of light are allowed to pass through the dual pass band filter element, thereby expanding the application field of the dual pass band filter element.

Abstract: The present invention relates to a retractable blowing exerciser, wherein the round cup is designed into a taper shaped radial face for matching and positioning of the arc of the ball body, a neck pipe is positioned below the base of the round cup to connect the integrated retractable ring so that the flat round body of the ring folds into the integrated extension coefficient, people can adjust the distance depending on their height for playing in the ball blowing area and achieve the practical benefits of fitness and entertainment for users in all ages anytime and anywhere.

Abstract: A rotatable water-spraying bat is disclosed. The bat comprises a soft material mount, a water storage cylinder and a push pushing-piston. The soft material covers the external of the water storage cylinder, and the inner diameter of the water storage cylinder provides the insertion of the pushing-piston cylinder as one unit. The bat is characterized in that at an open area of the water storage cylinder being provided with two fastening ring is mounted with a recess for the insertion of the corresponding L-shaped fastening plate and is then rotated, the protruded ring urges the recess to be in a fastening position so that the great impact onto the spray bat will not dislocate the spray bat the guiding corner at the front end of the recess allows the protruded ring to be engaged and dislocation is not possible.

Abstract: This invention having a torch body and an assembled cover to form an inner room which contains a PC Board, bulb holder and batteries; a button switch attached on the face of the torch cover with a L-arm part with a current conducting plate at the front end able to be connected to the PC Board; a light shade having a convex lens on its upper shell and with a lower shell made of diaphanous material; the PC Board with two diodes and one condenser to form an unstable oscillator is served to be an electric torch, flash warning tool and magnifying glass.
