  • Publication number: 20200298452
    Abstract: A method for manufacturing a cured product pattern of a curable composition includes the steps of, in sequence, depositing a droplet of the curable composition onto a substrate; bringing a mold having an uneven pattern formed in a surface thereof into contact with the curable composition; curing the curable composition; and releasing a cured product of the curable composition from the mold. The mold has a recess having a bottom surface and a stair structure arranged to form an opening surface that becomes wider from the bottom surface toward the surface of the mold. In the contact step, the curable composition comes into contact with the stair portion after a top of the droplet comes into contact with the bottom surface.

  • Patent number: 10538162
    Abstract: A power conversion system includes an AC to DC conversion circuit, a voltage detector, a step-down chopper circuit, a power conversion device for auxiliary power sources, and a control unit. The AC to DC conversion circuit converts AC power supplied from overhead wires via a transformer into DC power. The voltage detector detects a voltage of AC power supplied from the transformer. The step-down chopper circuit steps down the voltage of DC power produced through conversion by the AC to DC conversion circuit. The power conversion device for auxiliary power sources converts the DC power stepped down by the step-down chopper circuit into power for driving loads mounted in an electric vehicle and supplies it to the loads. The control unit controls the AC to DC conversion circuit and the step-down chopper circuit such that the voltage of AC power detected by the voltage detector approaches a reference voltage.

  • Patent number: 8353816
    Abstract: A capsule endoscope is swallowed by a patient, to capture images from inner wall surfaces of patient's digestive tract, while detecting imaging positions of the capsule endoscope. A doctor observes the images captured by the capsule endoscope, to select an aimed point image that contains a portion suspected of a lesion, and some images that represent pass points on an insertion route of a balloon endoscope. While a probing tip of the balloon endoscope is being inserted into the patient for the sake of thorough examination of the suspected portion, a degree of similarity between an image captured by the balloon endoscope and an image of a destination point, which is one of the pass points and the aimed point, is detected to judge by the similarity whether the probing tip has reached the destination point or not. So the doctor can get the probing tip to the aimed point easily.

  • Publication number: 20110057646
    Abstract: There is provided a position sensing apparatus when a non-orbital movable truck moves over a spherical surface, a cylindrical surface, or a flat surface, which is capable of position sensing even when, e.g., the non-orbital movable truck circumferentially moves over the spherical surface or the cylindrical surface to be hidden from the position sensing apparatus. A second linear encoder is disposed which includes a wire in a main body thereof to output an amount by which the wire is withdrawn as an encoder value. The tip of the wire of the second linear encoder is fixed to a position at the non-orbital movable truck to which the tip of the wire of a linear encoder is fixed. From an amount by which the wire of the linear encoder is withdrawn and the amount by which the wire of the second linear encoder is withdrawn, the position of the non-orbital movable truck is calculated in a calculation device.
