  • Patent number: 7297557
    Abstract: A method of attaching a molecular layer to a substrate includes attaching a temporary protecting group(s) to a molecule having a molecular switching moiety with first and second connecting groups attached to opposed ends thereof. The temporary protecting group(s) is attached to the first and/or second connecting group so as to cause the opposed ends of the switching moiety to exhibit a difference in hydrophilicity such that one of the ends remains at at least one of a water/solvent interface and a water/air interface, and the other end remains in air during a Langmuir-Blodgett (LB) process. An LB film is formed on the interface. The temporary protecting group(s) is removed. The substrate is passed through the LB film to form the molecular layer chemically bonded on the substrate. The difference in hydrophilicity between the opposed ends causes formation of a substantially well-oriented, uniform LB film at the interface.

  • Patent number: 7297416
    Abstract: Disclosed are photoluminescent tiles containing photoluminescent materials, and manufacturing methods thereof. A tile is filled or glazed with photoluminescent glaze powder including photoluminescent phosphor comprising a MAl2O4 compound (M: metal) as a matrix, and then baked, thereby obtaining the photoluminescent tiles. Since the photoluminescent tiles can be manufactured via a dry process, the manufacturing method is convenient and enables mass production via process automation. Additionally, the photoluminescent tiles of the present invention can be baked at a high temperature, and do not have degradations, such as fine cracks on the photoluminescent materials.

  • Patent number: 7298654
    Abstract: Disclosed is a non-volatile memory device and a method of erasing the non-volatile memory device. An erase voltage is simultaneously applied to a plurality of sectors contained in the non-volatile memory device. Then, erase validation is sequentially performed for each of the plurality sectors and results of the erase validation are stored in a plurality of pass information registers. According to the results stored in the pass information registers, sectors which were not successfully erased are simultaneously re-erased and then sequentially re-validated until no such “failed sectors” remain in the non-volatile memory device. Upon eliminating the “failed sectors” from the non-volatile memory device, a post-program operation is sequentially performed on each of the plurality of sectors.

  • Patent number: 7298565
    Abstract: A 2×2 opto-mechanical switch is disclosed. A first embodiment of the present invention utilizes a transmitting compact parallel prism and four or two pieces of the 45-degree prism to increase the beam separation. The compact parallel prism keeps a much smaller load to the relay arm. This makes the current invention less sensitive to the ambient shock and vibration. A second embodiment of the present invention utilizes a similar transmitting compact parallel prism and two wedge prisms which has similar advantages. The compact prism applies a small loading force to the relay arm. Both of these embodiments also feature superior thermal and mechanical stability. An opto-mechanical switch in accordance with the present invention utilizes a transmitting design and thus is more stable to ambient thermal or mechanical change. The embodiments of the present invention also feature much better repeatability than the conventional 2×2 optical switches.

  • Patent number: 7298177
    Abstract: A method and apparatus for determining the size of a keeper transistor in a dynamic circuit is provided. A first portion of a dynamic circuit, comprising the keeper transistor, is analyzed to determine keeper current data that describes what size the keeper transistor would need to be to supply a specified amount of keeper current. A second portion of the dynamic circuit is analyzed, separate from the first portion, to determine an estimated amount of leakage current that passes through the PDN when the PDN is not actively discharging the dynamic node may be determined. The size for the keeper transistor that enables the keeper transistor, when activated, to produce an amount of keeper current that is substantially equal to the estimated amount of leakage current may be determined based on the analysis performed on the first and second portion.
