  • Patent number: 7635459
    Abstract: Disclosed is a method of removing nitric acid from an aqueous liquid containing various components such as vegetable extract, and nitrate ion is removed selectively without spoiling the taste or other components, by subjecting the aqueous liquid to chromatographic treatment with an amphoteric ion exchanger to separate nitrate ion from other components contained in the aqueous liquid. A nitric acid-reduced drink is produced by preparing a raw drink material comprising an extract or juice of plant tissue; removing nitric acid from the raw drink material with use of the method of removing nitric acid from an aqueous liquid as described above; and preparing a drink using the raw drink material after the removing of nitric acid.

  • Publication number: 20090156112
    Abstract: A toxic gas exposure preventing system for an anatomic practice room is provided which not only can obtain a satisfactory toxic gas exposure preventing effect without impairing workability but also permits the use of existing dissecting tables as they are without requiring any special work such as an exhaust duct installing work. A push hood having a uniform air flow blow-off mechanism and a pull hood having an air flow suction/exhaust mechanism are disposed independently of each of the dissecting tables in such a manner that at least a portion of a uniform air flow passes in contact with a donor body on the dissecting table and is thereafter sucked into the pull hood. Further, a filter having a toxic gas adsorbing function is installed within the pull hood.

  • Publication number: 20080239905
    Abstract: In a device for detecting a focus error in controlling a position in an optical axis, a laser beam is split into first and second beam components, and one of the first and second beam components is diverged or converged. Then, the first and second beam components are superposed on each other, providing a single laser beam. The single laser beam is applied to an optical data-recording medium through an objective lens. The first laser beam component is focused on a first focusing point that is set at one side of the pinhole. The second beam component is focused on a second focusing point that is set at the other side of the pinhole.

A relationship between a recording track width Tw of the recording head and a reproduction width Tr of the reproducing head is defined as Tr>Tw. When conditions g<(1500/Hc-Hc/4000.pi.+0.3)/(Hc/400.pi.-1/2) and g.gtoreq.(1500/Hc-Hc/4000.pi.+0.3-Tp+Tw)/(Hc/400.pi.-1/2) are satisfied, an erase region is formed between the recording tracks. In this case, the gap length of the recording head is represented by g [.mu.m], the recording track width is represented by Tw [.mu.m], the track pitch is represented by Tp [.mu.m], and the coercive force of the recording medium is represented by Hc [Oe].
