Abstract: In one example, a semiconductor device comprises a substrate having a top surface and a bottom surface, an electronic device on the bottom surface of the substrate, a leadframe on the bottom surface of the substrate, the leadframe comprising a paddle, wherein the paddle is coupled to the electronic device, and a lead electrically coupled to the electronic device. The semiconductor device further comprises a first protective material contacting the bottom surface of the substrate and a side surface of the electronic device.

Abstract: A vehicle canister device includes a main canister including an inlet port through which evaporative gas is introduced from a fuel tank, an outlet port through which the evaporative gas introduced during operation of an engine is discharged to an intake side of the engine, and an internal space for filling activated carbon. The vehicle canister device also includes an auxiliary canister mounted in fluid-communication with the main canister and configured to allow external air to flow into the main canister through an atmosphere port provided on the main canister or the evaporative gas to flow therethrough upon stop of the engine. The auxiliary canister includes a plurality of activated carbon layers each filled with an activated carbon and a plurality of air layers disposed between the activated carbon layers.

Abstract: The invention provides a canister for reducing emissions of fuel gas. Fuel gas absorbed onto active carbon inside a canister can be easily desorbed from the active carbon and then flow into canister in the engine. The canister, which is combined with fuel tank and throttle pipe for absorption and desorption of fuel gas generated in fuel tank, has following components: a fuel tank port and an air inlet formed at the upper end of one side; a junction pipe arranged in upper parts of this side; a canister body with a plurality of convex is formed; a junction configured to fit the junction pipe on the canister body formed at upper end of the canister body and a plurality of hooks connected with a plurality of convexes on the canister body are provided; air inlet set on an upper side, a heater with a heater module is set inside.
