  • Patent number: 7927507
    Abstract: Compositions for hydrogen storage and methods of making such compositions employ an alloy that exhibits reversible formation/deformation of BH4? anions. The composition includes a ternary alloy including magnesium, boron and a metal and a metal hydride. The ternary alloy and the metal hydride are present in an amount sufficient to render the composition capable of hydrogen storage. The molar ratio of the metal to magnesium and boron in the alloy is such that the alloy exhibits reversible formation/deformation of BH4? anions. The hydrogen storage composition is prepared by combining magnesium, boron and a metal to prepare a ternary alloy and combining the ternary alloy with a metal hydride to form the hydrogen storage composition.

  • Patent number: 7919384
    Abstract: A method of making planar-type bottom electrode for semiconductor device is disclosed. A sacrificial layer structure is formed on a substrate. Multiple first trenches are defined in the sacrificial layer structure, wherein those first trenches are arranged in a first direction. The first trenches are filled with insulating material to form an insulating layer in each first trench. Multiple second trenches are defined in the sacrificial layer structure between the insulating layers, and are arranged in a second direction such that the second trenches intersect the first trenches. The second trenches are filled with bottom electrode material to form a bottom electrode layer in each second trench. The insulating layers separate respectively the bottom electrode layers apart from each other. Lastly, removing the sacrificial layer structure defines a receiving space by two adjacent insulating layers and two adjacent bottom electrode layers.

  • Patent number: 7916821
    Abstract: A method and apparatus are provided for substantially reducing or eliminating the timing skew caused by delay elements in a delay locked loop. A method and apparatus are disclosed wherein a rising edge of a local timing signal is established and phase-locked to a rising edge of a system clock signal by delaying the system clock signal. A falling edge of the local timing signal is established and phase-locked to a falling edge of the system clock signal by further delaying only a portion of a signal representative of the delayed clock signal. By separately delaying different portions of the system clock signal and using the separately delayed portions to establish a local timing signal, a local timing signal may be established which is compensated for the varied effects of delay elements in a delay locked loop.

  • Publication number: 20110044856
    Abstract: A drug test device for bodily fluids, such as urine, includes a cup and a removable lid which houses one or more test strips. The lid is releasably locked onto the cup so as to align dipping ends of the test strips exposed through an underside of the lid with a position stabilizer, thereby causing the dipping ends to be located downwardly and submerged in fluid when the device is placed on its side in a reactive position. The position stabilizer may comprise a sidewall indentation that reduces the internal volume of the cup and keeps the cup from rolling when placed on its side.
