Abstract: A semiconductor package includes a first die, a second die and a redistribution layer structure. The first die and the second die are disposed laterally. The redistribution layer structure is disposed over and electrically connected to the first die and the second die, wherein the redistribution layer structure includes a plurality of vias and a plurality of lines stacked alternately and electrically connected to each other and embedded by a plurality of polymer layers, and wherein from a top view, first vias of the plurality of vias overlapping with the first die or the second die have an elliptical-like shape.

Abstract: A method of manufacturing a car wax spray, particularly to the one stored in the decomposed liquid state in a storage bottle that will turn into solid state after being sprayed out from the storage bottle. The present invention comprises the steps of filling 55% of the solid wax into the bottom of a storage bottle, and then 35% of the soluble gaseous propane to dissolve and decompose the solid wax into a concentrated liquid state, and then filling 10% of the volatile butane into the storage bottle to dilute the concentrated wax liquid by the movement of two steel beads into a diluted ready liquid, such that when the air pressure sprays out the wax, the butane is oxidized by the air and is vaporized instantly, and the even film remaining after the spray will resume its original solid state.

Abstract: A grease atomizing nozzle comprises a jet tube with a concave ring shaped depression at a middle section thereof. Two tapered holes with large openings facing outwards are formed at the ring. A jet opening penetrates through a top side of the jet tube. A lower end of the opening is perpendicular to the tapered holes. A lower end of the jet tube is formed with a tapered surface which applies a pressure to a resilient spring tberebelow. A seat below the jet tube is a cylindrical body with a cavity formed therein. A plurality of concave trenches radially spaced are formed in the cavity. These trenches are perpendicular to an inner surface of the cavity; and a gas inlet being formed at an upper side of the cavity.

Abstract: A rail including a number of slots being longitudinally formed therein and a number of options each including a guide being slidably engageable in the slots. Each slot consists of a wide portion and a narrow portion. The wide portion of each slot is proximate to the axis of the rail while the narrow portion of the same is distal from the axis of the rail. Each guide has a form being compensative to that of each slot. Thus, each option will not be radially disengaged from the rail when the guide of the option is engaged in a corresponding slot formed in the rail.
