  • Patent number: 8261364
    Abstract: An administration server determines whether a request from a first client terminal is for authentication of a specific user who is in a log-in state via a second client terminal. When the request is for the specific user, the administration server performs a first or a second control, the first control including creating a new password; replacing an old password that is for the specific user to log-in to a network via the second client terminal with the new password; and sending the new password to the first client terminal, and the second control including determining that the request is disapproval; and sending a result of disapproval to the first client terminal. A double-log in by the same user and crush of an individual storage unit caused by a double-log in with the same user ID can be prevented.

  • Patent number: 8198090
    Abstract: A cartridge is provided that can remove a residual liquid all around the leading end of a pipette, without requiring any new equipment, regardless of the viscosity of the residual liquid. This cartridge includes a plurality of tanks, each of which has an upper opening, and a liquid is introduced into or led out from at least one of the plurality of tanks 110 to 119 with a pipette. The cartridge further includes waste liquid tanks 120 to 122. The waste liquid tanks 120 to 122 each includes a capillary phenomenon generation portion. A residual liquid present at the leading end of the pipette is brought into contact with the capillary phenomenon generation portion of the waste liquid tanks, and the residual liquid is transferred to the capillary phenomenon generation portion through the capillary phenomenon to be removed from the pipette.
