  • Patent number: 10933413
    Abstract: An analyzing device has one end of a supplying capillary channel opened at a spot application section formed so as to protrude from an analyzing device main body. The supplying capillary channel is connected to a microchannel structure formed inside the analyzing device main body. A sample liquid is applied to the spot application section and is suctioned by a capillary force of the supplying capillary channel. The analyzing device is used for reading in which a suctioned solution is accessed. The analyzing device includes a leading end of the spot application section that has an inclined face. The end of the supplying capillary channel is opened on the inclined face.

  • Publication number: 20200108384
    Abstract: A capillary cavity 19 and an inlet 13 protruding circumferentially outward from an axial center 107 are connected by a guide section 17 formed so as to extend circumferentially inward and on which a capillary force acts. A sample liquid collected from a leading end of the inlet 13 is transferred to a separation cavity 23. A bent section 22 and a recess 21 are formed at a connected section of the guide section 17 and the capillary cavity 19 so as to change the direction of a passage.

  • Patent number: 9757722
    Abstract: An analyzing device has a main body and is configured to draw a sample liquid from a spot application section of the main body and transfer the sample liquid to a measurement chamber via a microchannel structure formed inside the main body by a centrifugal force. The spot application section has an inlet. The analyzing device includes a supplying capillary channel formed within the spot application section. The supplying capillary channel has an end connected to the inlet of the spot application section. The analyzing device also includes a holding chamber connected to another end of the supplying capillary channel and having a thickness sized to generate a capillary force to move the sample liquid. The holding chamber is formed between a first side wall and a second side wall. The first side wall and the second side wall define the holding chamber.

  • Patent number: 9145579
    Abstract: A feature of an analyzing device is that a peeling portion (14) extending outward is partially connected to the outer edge of a reagent retaining portion (13) that is formed in a separating chamber (6) provided in a main unit case (2) and retains a reagent (8). With this configuration, when a droplet of the reagent (8) is dried and fixed on the reagent retaining portion (13), an external force applied to the droplet can be smaller than that on other portions. The dried reagent (8) starts shrinking from the position of the peeling portion 14. At the completion of drying, the reagent (8) can be smaller in size than the reagent retaining portion (13) in plan view and can be larger in thickness than the related art.

  • Patent number: 8899485
    Abstract: In a read label as an information recording medium and a method for recording information thereon according to the present invention, the read label includes: an adhesive layer 3; a metal film layer 4 disposed on the surface of the adhesive layer 3; and a light-transmissive protective film layer 5 disposed on the surface of the metal film layer 4. The adhesive layer 3 and the light-transmissive protective film layer 5 are larger in thickness than the metal film layer 4, and an evaporated and removed portion is formed in a part of the metal film layer 4 by radiating a laser beam from the side of the light-transmissive protective film layer 5.

  • Patent number: 8596150
    Abstract: An inlet (37a) of a capillary tube channel that feeds a liquid from a mixing cavity (39) to measurement spots is formed near one (4) of the wall surfaces of the upper and lower surfaces of the mixing cavity (39) situated in a direction of oscillation for mixing. On the other wall surface (3), a level difference (39a) is formed such that an inner gap is larger than an outer gap in the mixing cavity (39), so that a solution is reliably fed from the mixing cavity to the measurement cells.

  • Patent number: 8084165
    Abstract: An MEA having an MEA body part 5C; a frame 6 made of a plate-like thermoplastic resin; and gaskets 7 formed on opposed surfaces of the frame 6 so as to hold the frame 6 between. The gaskets 7 each have an annular portion 7A that is annularly formed so as to extend along the inner periphery of the frame 6 and elongated portions 7B1 to 7B8 that extend from the annular portion 7A and come into contact with the side faces of an associated electrode layer 5C after passing over the inner periphery of the frame 6 and a peripheral region 5D of a polymer electrolyte membrane.
