  • Publication number: 20130245540
    Abstract: A producing method for a living organism-applicable hydrogen-contained fluid, which includes hydrogen molecules in living organism-applicable fluid enclosed in a container (2i) with hydrogen molecule permeability, is provided. This method includes a hydrogen exposing step of exposing hydrogen molecules to the container (2i) in which the living organism-applicable fluid is enclosed from the outside of the container without opening the container. The container with hydrogen molecule permeability is one that allows a dissolved hydrogen concentration of a normal saline solution to be 1 ppb or greater when the container filled with the normal saline solution is immersed for 5 hours in a volume of hydrogen water, which stably maintains an approximately saturated state (1.6 ppm at 20 C degrees under 1 barometric pressure) and is 20 times the content volume of the container.

    Abstract: A method, a device, and a computer-readable medium for simulating a multilayer optical storage medium are disclosed. A multiple-layer optical storage medium is simulated by using a set of multiple single-layer media, wherein the number of multiple single-layer media is equal to or smaller than the number of multiple layers of the multiple layer optical storage medium, and each single layer of the set of multiple single-layer media comprises a copy of the corresponding layer of the multiple-layer medium. This is transparent to any application software accessing a device having such a single-layer medium inserted therein by the drive reporting to the application that a multi-layer optical storage medium has actually been inserted into the device for reading or writing. The device may be comprised in an audio-visual player and/or a recorder such as a DVD recorder.
