Abstract: A composite lubricant for recording disk media, a recording disk media including a layer of the composite lubricant, and method of manufacturing the same are described. The composite lubricant may include a non-phosphazene component and a phosphazene component where the non-phosphazene component is a difunctional perfluoropolyether compound terminated with first and second polar end groups, the first polar end group comprising a first number of hydroxyls and the second polar end includes a second number of hydroxyls, greater than the first number of hydroxyls. The phosphazene component may be a difunctional perfluoropolyether compound terminated with a phosphazene functional group and with a third polar end group, the third polar end group comprising a third number of hydroxyls equal to the second number of hydroxyls.

Abstract: A handy information display system is disclosed. The system has three main components: a light emitting diodes (LED) array display board, an information server and a portable unit. The LED array display board includes a plurality of light emitting diodes and photodetectors. It can be used to display alphabets, numbers and simple graphics. While it visually gives an effectively stationary message display, the LED can also be modulated to transmit high frequency signals. The modulating frequency should be high enough to be imperceptible by humans. Both message display and signal transmission are controlled by an information server. The system further comprises at least one portable unit. The portable unit is equipped with an optical transceiver and a visual display unit. The optical transceiver can detect the signals transmitted from the LED array display board. The visual display unit then shows the information corresponding to the received signals.

Abstract: A process for producing a ferroelectric lead zirconate titanate dielectric for a semiconductor device by applying a lead titanate seeding layer to a substrate before applying the lead zirconate titanate film, and a semiconductor device produced in accordance with the process. The lead titanate seeding layer allows the subsequent lead zirconate titanate to be annealed at a significantly lower seeding temperature, to lessen interdiffusion among the films, electrodes and substrate and to lessen thermal stresses.
