  • Patent number: 8770046
    Abstract: An autosampler is provided with a needle, a measuring pump which sucks and discharges liquid through the needle, a movement mechanism for the needle, and an injection port which has a needle sealing surface. A sample liquid is sucked into the needle and then the sample liquid discharged with the tip of the needle pressed to the needle sealing surface. When cleaning the needle sealing surface, a cleaning liquid within the injection port is sucked and then the cleaning liquid is discharged and sucked into the injection port at a position at which the tip of the needle does not make contact with the needle sealing surface. Alternatively, after the cleaning liquid is discharged into the injection port, the needle may be caused to perform an up and down motion such that the tip of the needle contacts the needle sealing surface and then is lifted.

  • Publication number: 20140149623
    Abstract: A disclosed information processing apparatus includes: a first processing unit; and a second processing unit that is in either of an operational state and a suspended state. The first processing unit and the second processing unit are coupled by a first signal line through which a first signal that represents a state of the second processing unit passes and by a second signal line through which a second signal that causes an interrupt to the second processing unit passes. The second processing unit outputs the first signal according to a state of the second processing unit. The first processing unit determines, based on the first signal, whether the first processing unit causes the second processing unit to resume. When the first processing unit causes the second processing unit to resume, the first processing unit outputs the second signal, and the second processing unit resumes, upon receiving the second signal.

  • Patent number: 8194161
    Abstract: An easy and inexpensive signal readout method is provided for a photodiode array consisting of n pieces of photodiodes whose signals are sequentially read out from the first through nth photodiodes. The method includes a canceling process that is performed one or more times before performing a complete readout operation for sequentially reading out signals from all the photodiodes, and the canceling process includes the steps of sequentially reading out signals of a predetermined number of photodiodes starting from the first photodiode to cancel the signals of these photodiodes and then returning to the readout of the signal of the first photodiode. According to this method, it is possible to easily set an appropriate charging time for each photodiode and yet prevent the photodiodes from becoming saturated.
