  • Publication number: 20240301476
    Abstract: An analysis method according to the present disclosure includes: mixing a binding substance and a sample including a target substance. The binding substance includes a nucleic acid region composed of a nucleic acid and having activity to bind to the target substance; removing the binding substance not bound to the target substance; amplifying the nucleic acid region; and detecting a phenomenon caused by the amplification of the nucleic acid region. For example, the analysis method includes: forming a complex of a template nucleic acid including a sequence complementary to a 3? side sequence of the nucleic acid region; and amplifying the nucleic acid region by an action of a nucleic acid amplifying enzyme using the complex as a starting point.

  • Publication number: 20240241078
    Abstract: An ion sensor includes an ion detection element, a reference electrode that provides a reference point of a potential, and a solution in which an ion concentration can be changed in a sensing area of the ion detection element. The sensing area of the ion detection element is disposed in the solution. A method for detecting a target substance employs an ion sensor. The target substance bound to a label having a function of changing the amount of ions detectable by the ion sensor is introduced into the solution, and a change in the amount of ions is detected using the ion sensor.

  • Patent number: 9531243
    Abstract: A motor includes an attachment portion, a first circuit board, and a second circuit board. The attachment portion is fixed to a frame of an apparatus to be driven by the motor. The first circuit board is located axially below coils and axially above the attachment portion. End portions of conducting wires defining the coils are connected to the first circuit board. The second circuit board is located axially below the attachment portion. An AC to DC conversion portion is mounted on the second circuit board. In addition, the attachment portion is arranged between the first and second circuit boards.

  • Publication number: 20090039725
    Abstract: A servo unit is arranged to operate an actuator, and a brushless motor is utilized in the servo unit. The brushless motor includes a rotational portion provided with a shaft and a rotor magnet rotating integrally with the shaft, a bearing portion rotatably supporting the shaft, a housing provided with a cylindrical portion retaining the bearing portion and a base portion bulging radially outwards from an axially lower portion of the cylindrical portion, a stator provided with a stator core having an inner peripheral surface to radially oppose an outer peripheral surface of the cylindrical portion of the housing and coils formed by conductive wires wound around the stator core, and a motor circuit board disposed on an axially upper side of the base portion. The base portion of the housing is arranged on an outer peripheral surface with a substantially arcuate concave portion which is concave in a radially inward direction.

  • Publication number: 20080012452
    Abstract: To control low-speed rotation of a motor, a contact-less sensor for reading rotation information on the back surface of a discoid disc is fixed on a radially outside portion of a rotary part. The distance between a detection face of the contact-less sensor and the back surface of the discoid disc is adjusted by bending a mounting plate.
