Abstract: A semiconductor structure includes a first interposer; a second interposer laterally adjacent to the first interposer, where the second interposer is spaced apart from the first interposer; and a first die attached to a first side of the first interposer and attached to a first side of the second interposer, where the first side of the first interposer and the first side of the second interposer face the first die.

Abstract: A dual-head fan is disclosed herein, comprising a drum fan, a first wind shell on the drum fan, an outer shield on one side of the first wind shell, a moving panel accommodated in the first wind shell, a supporting plate at a top of the first wind shell and having a hollow portion at a center thereof and an engaging part in a middle of the hollow portion for engaging with an upper end of the moving panel by one side thereof, an air duct baffle engaged with the other side of the engaging part of the supporting plate and having two laterals connected with a second wind shell and a lower outlet shell having a top surface, and an upper outlet shell rotatably connected on upper sides of the second wind shell and the lower outlet shell to regulate airflow direction by rotation.

Abstract: A ceiling mounted air purifier is disclosed, comprising a winnower having two winnower air entrances on two sides thereof, a winnower air exit, and a windshield; a base having a recessed groove below a middle thereof for accommodating the winnower, two air inlet passages disposed on two sides of the recessed groove respectively, and an integrated air exit disposed at a top thereof for tightly connecting the winnower air exit of the winnower by the windshield; a back shell disposed at a bottom of the base to position the winnower in the recessed groove and seal bottoms of the two air inlet passages; two air inlet filters respectively inserted into exits of the two air inlet passages and corresponding to the two winnower air entrances; a filter cartridge container disposed on the winnower air exit; and a front shell disposed at the top of the base to release filtered air.

Abstract: A hot and cool fan is revealed. An air distribution unit and a feed unit are mounted in a fan body. The feed unit consists of a driving part and a driven part connected to each other. An electric heating unit is connected to the driven part for being moved to be aligned with or away from an air exhaust part of the air distribution unit. Air from the air exhaust part is heated by the electric heating unit when the electric heating unit is aligned with the air exhaust part. Air is blown out of the air exhaust part smoothly when the electric heating unit is away from the air exhaust part of the air distribution unit. Thereby the fan is switched between a warm mode and a cold mode easily and there is a sufficient amount of wind available.
