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 polyphenylene ether bismaleimide resin is provided. The polyphenylene ether bismaleimide resin (PPE-BMI) is formed from a modified polyphenylene ether diamine and a maleic anhydride by a condensation polymerization. The modified polyphenylene ether diamine is formed by reacting a phenol-based compound with a polyphenylene ether.

Abstract: A polymer resin includes a copolymer of polyethylene terephthalate (PET). In the process of preparing PET, part of ethylene glycol is replaced with other components to obtain the copolymer of PET.

Abstract: A ladder balance adjusting apparatus installed on an n-shaped ladder leg includes an assembly, a base cover, a fixing element, a base cup, a stand rod, and a control element. The assembly has a first component and a second component, and the second component has a side and a bottom to form an L-shaped structure, and after the ladder leg is installed between the two components, the ladder leg is locked by a plurality of locking elements. The base cover is coupled to the assembly and the base cup, and the fixing element is built in the base cover, and the stand rod is provided for passing the aforementioned elements to support the ladder leg, and the control element is provided for controlling the fixing element to adjust the height of the ladder leg, and to simplify the manufacturing process of components, the installation and disassembly of the apparatus.

Abstract: A heat dissipation connector capable of dissipating heat from electric appliances in relative close proximity, such as a personal computer and possesses one or more USB ports for connecting to other electrical appliances. Specifically, the present invention is provided with at least two USB ports. One USB port is capable of receiving electrical power supplied from a USB port of a connected electric appliance such as a personal computer for driving built-in fans of the present invention.

Abstract: A heat dissipation connector of the invention is not only an externally auxiliary heat dissipation device used beside relative electric appliance such as PC or the like to do heat dissipated away from relative electric appliance, but also an externally auxiliary connector to provide one or more USB ports to be used for other electric appliance.

Abstract: A fast rotation joint is disclosed. The fast rotation joint is engaged between a machine body and a joint of the transferring flexible tube. The fast rotation joint includes mainly a first main body, a second main body, and a third main body. A drain-preventing pad is illustrated between the first main body and the second main body. The drain-preventing pad is used to prevent air from drainage so that the pressure will be insufficient. A plurality of rollers are mounted between the second main body and the - :third main body for preventing the deformation from the engagement of the machine body with the transferring flexible tube so as to increase the lifetime of the transferring flexible tube and the joint.
