  • Publication number: 20080118639
    Abstract: A process for forming a unidirectionally oriented fiber structure formed of high tenacity fibers. A plurality of yarns of high tenacity fibers are supplied, with the yarns being unidirectionally oriented. The yarns are coated with a liquid having a viscosity of about 5 to about 600 centipoises and tension is applied to the yarns. The yarns are passed through a fiber spreading device and the yarns are dried. The yarns are reduced in thickness and increased in width after passing through the fiber spreading device, with the fibers forming the yarns being spread apart, thus providing a relatively thin unidirectionally oriented fiber structure.

  • Patent number: 6970395
    Abstract: A memory device includes a delay-locked loop circuit having delay elements and a synchronization circuit coupled to the delay-locked loop circuit. The synchronization circuit receives a synchronization enable signal and outputs a plurality of enable signals, including an enable signal coupled to an output circuit. Because the enable signal is synchronized with the read signal, it is possible to provide more time to read data into the buffer. A method of reading data from a memory device couples a synchronization enable signal and an external clock signal to a synchronization circuit. A read signal and an output enable are generated based upon a synchronization enable signal and a delayed clock signal of the external clock signal. Because the output signal is synchronized to the read signal, more time is allowed for the sense function.
