  • Publication number: 20090266187
    Abstract: Under a state of a normal temperature, a pitch B2 of a feed nut 55, 65 is formed to be slightly larger than a pitch A2 of a feed shaft screw 53, 63. Accordingly, since the screw thread of the feed nut 55, 65 is pressed to the screw thread of the feed screw shaft 53, 63 with a small interference, there is no backlash between the feed screw shaft 53, 63 and the feed nut 55, 65 so that a smooth feeding operation can be carried out. Under a state of a low temperature, the feed nut 55, 65 contracts more than the feed screw shaft 53, 63. As a result, a pitch B1 of the feed nut 55, 65 has the substantially same dimension as that of a pitch A1 of the feed screw shaft 53, 63.

  • Publication number: 20080233634
    Abstract: A nucleic acid detection device is provided with a closed channel formed of a first channel portion, through which a washing reagent storage section for storing a washing reagent for washing a detection section for nucleic acid detection communicates with the detection section, and a second channel portion through which a pretreatment section for nucleic acid treatment communicates with the detection section. The closed channel is connected with a gas inlet/outlet path for communication with the outside. The gas inlet/outlet path is blocked by a sealing mechanism before nucleic acid detection. In storing a pretreatment reagent and the washing reagent frozen, the gas inlet/outlet path is kept open and connected to the channel. Thus, there is provided a nucleic acid detection device having a structure for preventing leakage of nucleic acid samples to the outside and which can be stored for a long period of time with the reagents therein.
