  • Patent number: 11135102
    Abstract: A plurality of openings (11) is formed in a region corresponding to at least a body fluid discharge region (H) of a liquid permeable top sheet (3). A polymer sheet (6) disposed adjacent to a surface of an absorbent body (4) side of the liquid permeable top sheet (3) is included, and the polymer sheet includes highly absorbent resin disposed along a longitudinal direction on both sides of the region corresponding to the body fluid discharge region (H). Upon the highly absorbent resin becoming swollen by absorption, a space (10) for holding a body fluid is formed between regions in which the highly absorbent resin is disposed (12) and also between the liquid permeable top sheet (3) and the polymer sheet (6).

  • Patent number: 10170486
    Abstract: Probability of malfunction of a semiconductor storage device is reduced. A shielding layer is provided between a memory cell array (e.g., a memory cell array including a transistor formed using an oxide semiconductor material) and a peripheral circuit (e.g., a peripheral circuit including a transistor formed using a semiconductor substrate), which are stacked. With this structure, the memory cell array and the peripheral circuit can be shielded from radiation noise generated between the memory cell array and the peripheral circuit. Thus, probability of malfunction of the semiconductor storage device can be reduced.

  • Patent number: 8173790
    Abstract: An objective of the present invention is to provide polynucleotides encoding insect desiccation resistance proteins, and uses thereof cDNA libraries were produced from Polypedilum vanderplanki larvae in a desiccated state, a P. vanderplanki EST database was constructed, and genes encoding LEA proteins were isolated. This resulted in the successful isolation of three types of novel gene encoding LEA-like proteins (PvLEA1, PvLEA2, and PvLEA3.) When secondary structure predictions and motif searches were performed on the proteins deduced from each of the genes, all three proteins had ?-helix-rich structures and LEA_4 motifs, which are characteristic of LEA proteins. Moreover, the recombinant proteins synthesized from PvLEA1, 2 and 3 genes were heat soluble even when boiling, so that PvLEA1, 2 and 3 proteins have highly hydrophilic property as well as plant LEA proteins. Therefore, the three isolated genes were found to be novel P. vanderplanki-derived LEA genes.

  • Patent number: 8098988
    Abstract: A disclosed optical add/drop multiplexing device demultiplexes a first signal into multiple signals according to wavelengths, drops one or more of the demultiplexed signals to a transponder, adds one or more signals output from the transponder, multiplexes these signals into a second signal, and outputs it. The device includes an injecting unit for injecting one of measurement signals, each of whose wavelength corresponds to that of a different demultiplexed signal, into a core of a multicore cable within the device, the core being used to transmit the different demultiplexed signal having the corresponding wavelength; a preventing unit for preventing the one measurement signal from emanating; a measuring unit for measuring, for each wavelength, levels of the one measurement signal before and after the corresponding core; a calculating unit for calculating loss of the corresponding core, based on the measured levels; and an informing unit for reporting the calculated loss.
