  • Publication number: 20060292039
    Abstract: It becomes possible for a user to check his/her own health state at a desired place without visiting inspection agencies. Furthermore, it becomes possible for a user to conveniently check his/her own health state. First, a user collects body fluid to be a measurement object, such as blood, saliva, and urine. Then, the collected body fluid is introduced to the chip (101) as a sample. Then, the sample is made to act on a detection reagent which acts on a specific component in the sample to generate a predetermined detection reaction. This chip (101) is set to the mobile terminal (127). A measurement unit (151) of the mobile terminal (127) measures an amount of a specific component in the sample by means that product of reaction is quantitated by an optical method or the like. The mobile terminal (127) transmits the measurement value to an analysis center (153).

  • Publication number: 20060233474
    Abstract: A slider is displaceable in an axial direction on guide sections of a cylinder tube through a guide mechanism. A first elastic member is interposed between a first bearing support member of the guide mechanism and one retaining section of the slider. A bearing installed in the first bearing support member, is pressed continuously toward the guide section. A second bearing support member is installed via a second elastic member between the guide section and another retaining section of the slider. A bearing provided on the second bearing support member is pressed toward the guide section by means of a resilient force of the second elastic member.

  • Publication number: 20060230923
    Abstract: A coupler is provided inside an engaging hole of a piston yoke, which is connected to pistons. A slider is installed on an upper portion of the coupler through a coupler-insertion hole. An engaging member, provided at a lower portion of the coupler, is inserted into the engaging hole so as to be displaceable by a slight amount in the widthwise direction of a cylinder tube. The coupler is inserted into the coupler-insertion hole of the slider, so that the coupler-insertion hole is slidable with respect to curved surface sections of the coupler.

  • Publication number: 20060233475
    Abstract: A slider is displaceable in an axial direction on guide sections of a cylinder tube. Bearings are installed with the slider, so that the bearings are opposed to the guide sections. Bearings are also installed on first and second bearing support members, which are provided respectively at retaining sections of the slider. When the slider is displaced in the axial direction along the cylinder tube, only one end surface of one of the flange sections of the bearing is pressed, depending on the displacement direction of the slider, in order to effect displacement in an integrated manner.

  • Publication number: 20060214101
    Abstract: After a sample is previously separated into plural components in a channel formed in a microchip (353), the channel is irradiated along a separation direction with a laser beam from a laser oscillator (361) to sequentially ionize each fraction separated in the channel. The ionized fraction is detected by a mass spectrometry unit (363) and analyzed by an analytical result analyzing unit (371). The analytical result is stored in a memory (369) while associated with position information in a driver control unit (367) and information on laser beam irradiation condition in a laser control unit (373), and the analytical result is imaged by an imaging unit (375). The imaged analytical result is displayed on a display (377).

  • Publication number: 20060102836
    Abstract: A liquid sample (104) introduced in a main flow passage (101) is held in a dam portion (105), and a trigger liquid (106) is filled in a trigger flow passage (102). In this state, the trigger liquid (106) is further introduced at desired timing into the trigger flow passage (102) so that the front end portion of the level of the trigger liquid (106) is advanced and the front end portion is brought to be into contact with the dam portion (105). This causes the liquid sample (104) to move to the right (downstream side) in the figure, resulting in the liquid sample (104) flowing out to the downstream side of the main flow passage (101). This means that the trigger liquid (106) provides priming to realize a liquid switch.

  • Publication number: 20060070951
    Abstract: A particular component in a sample is recovered in a high concentration and solvent-replaced. A separator 100 is placed on a microchip and includes a channel 112 for flowing the particular component. The channel 112 includes a sample feeding channel 300 as well as a filtrate discharge channel 302 and a sample recovering part 308 which are branched from the sample feeding channel 300. There is formed a filter 304 for preventing passage of the particular component, at the inlet of the filtrate discharge channel 302 from the sample feeding channel 300. Furthermore, there is formed a damming area (hydrophobic area) 306 for preventing entering of a liquid sample while allowing for passage of the liquid sample by applying an external force equal to or larger than a given level, at the inlet of the sample recovering part 308 from the sample feeding channel 300.

  • Publication number: 20060063273
    Abstract: Individual components are separated with a high concentration and accurately, from a sample containing components-to-be-separated. The separation apparatus includes a channel through which a sample containing components-to-be-separated moves; and gateway portions partitioning the separation channel into a plurality of compartments. The separation apparatus further includes an external force imposing unit, which imposes external force to the components-to-be-separated so as to allow them to move through the channel. The external force imposing unit is configured so as to alternately repeatedly execute a first external force imposing pattern by which the external force is imposed in the forward direction of the channel, and a second external force imposing pattern by which the external force is imposed in the direction opposite to the forward direction along the channel. This makes it possible to fractionate the components-to-be-separated into any of the compartments.

  • Patent number: 6970050
    Abstract: An oscillator includes a transistor, a first bias resistor connected between the base of the transistor and a power input terminal, and a second bias resistor connected between the base of the transistor and a control-voltage input terminal. When the control-voltage input terminal is grounded, the bias voltage at the base of the transistor is below a predetermined threshold, thus causing the oscillator to stop oscillation. When the control-voltage input terminal is open, the bias voltage at the base of the transistor is above the threshold, thus causing the oscillator to start oscillation.
