摘要:
An exemplary semiconductor die package is disclosed having one or more semiconductor dice disposed on a first substrate, one or more packaged electrical components disposed on a second substrate that is electrical coupled to the first substrate, and an electrically insulating material disposed over portions of the substrates. The first substrate may hold power-handling devices and may be specially constructed to dissipation heat and to facilitate fast and inexpensive manufacturing. The second substrate may hold packaged components of control circuitry for the power-handling devices, and may be specially constructed to enable fast and inexpensive wiring design and fast and inexpensive component assembly. The first substrate may be used with different designs of the second substrate.

A guide mechanism and the optical drive utilizing the same. The guide mechanism includes a guiding base, a first axial fixing member, a driver, and a rotary structure. The guiding base comprises a first opening and a second opening. The first axial fixing member is disposed at a side of the guiding base. The driver, disposed at an opposite side of the guiding base, comprises an opening and a second axial fixing member. The rotary structure is fixed between the first axial fixing member and the second axial fixing member, comprising a spindle and a magnetic structure. The spindle comprises an operating region and a connecting portion having a maximum outer diameter smaller than a minimum outer diameter of the operating region. The magnetic structure is attached to the connecting portion and disposed in the opening.

A multiple die package includes a folded leadframe for interconnecting at least two die attached to another leadframe. In a synchronous voltage regulator the folded leadframe, which is formed from a single piece of material, connects the high side switching device with the low side switching device to provide a low resistance, low inductance connection between the two devices.

A resistive circuit includes a first terminal and a second terminal and polycrystalline first and second resistive segments coupled between the first and second terminals. A third terminal A is coupled to the first resistive segment, and a third terminal B is coupled to the second resistive segment. The third terminal A has a first voltage with respect to the first terminal, and the third terminal B has a second voltage with respect to the second terminal. With this arrangement, the non-linearity of resistance of the first resistive segment at least partially compensates for non-linearity of resistance of the second resistive segment.
摘要:
An extremely ductile fiber reinforced brittle matrix composite is of great value to protective structures that may be subjected to dynamic and/or impact loading. Infrastructures such as homes, buildings, and bridges may experience such loads due to hurricane lifted objects, bombs, and other projectiles. Compared to normal concrete and fiber reinforced concrete, the invented composite has substantially improved tensile strain capacity with strain hardening behavior, several hundred times higher than that of conventional concrete and fiber reinforced concrete even when subjected to impact loading. The brittle matrix may be a hydraulic cement or an inorganic polymer. In an exemplary embodiment of the teachings, the composites are prepared by incorporating pozzolanic admixtures, lightweight filler, and fine aggregates in Engineered Cementitious Composite fresh mixture, to form the resulting mixtures, then placing the resulting mixtures into molds, and curing the resulting mixtures.
