  • Patent number: 7712251
    Abstract: In a method and apparatus for severing roots of bean sprouts, a severing table has a plurality of ridges formed at predetermined intervals and extending in parallel with a direction in which a cutter blade is moved. Each ridge is formed with a number of severing slits each of which has such a width that a root of a bean sprout falls into each severing slit. The bean sprouts are continuously supplied onto the severing table while a cutter blade is moved along an upper face of the severing table and air is being blown from above the severing table so that roots of the bean sprouts on the severing table flow into the severing slits. The roots of the bean sprouts fallen in the severing slits are severed by the cutter blade. The bean sprouts from which the roots have been severed are conveyed out of the severing table with movement of the cutter blade.

  • Publication number: 20040003275
    Abstract: To protect secrecy of information processed by a computer system by performing access control and encryption by using a group identifier as a key, an information storage (1) of the computer system includes an arithmetic processing unit (2) which generates a specific number (ID) for identifying the information storage (1) through parameter arithmetic on the basis of medium information (DD) which identifies definitely a data storing medium and specific information (SD) obtained by grouping environment information on a per species basis. The specific number (ID) is stored in a nonvolatile memory (6) or an information recording medium (7) as the group identifier (ID). An information recording medium control unit (5) manages the information on a per group basis on the basis of the specific number (ID). Information can be laid open in personal computers belonging to a same group while being protected from leakage to third party.

  • Patent number: 6544572
    Abstract: Bean sprouts conveyed on a conveyor are caused to fall into a number of cylindrical cases moved on an upper severing table so that the bean sprouts are enclosed in the respective cases in a standing state. Air is caused to blow from over the cylindrical cases by a blowing casing so that downward roots or leaves of the bean sprouts in the cylindrical cases are caused to fall into the severing slits. A first severing work is carried out in which the root or leaf of the bean sprout is held between a lower edge of the cylindrical case and an edge of the severing slit to be severed. A second severing work is then carried out in which the cylindrical cases are inverted upside down so that the bean sprouts in the cases are inverted upside down and so that the downward roots and leaves of the bean sprouts are severed by the lower severing table.
