  • Publication number: 20220227567
    Abstract: A measuring container comprises a storage container and a storage section selector. The storage container includes storage sections each capable of storing a predetermined number of tablets. The storage section selector is attached to the storage container and has a second path that allows the tablets to pass through from one end to an other end. The one end of the second path is connected to an outside, and the other end is selectively connected to one of the storage sections.

  • Patent number: 11087904
    Abstract: A multicore cable includes two-core parallel electric wires, wherein the two-core parallel electric wires each includes two conductors; an insulating layer that covers a periphery of the two conductors and having first and second flat portions and first and second semicircular portions; a first shield tape that covers a periphery of the insulating layer; a drain wire arranged inside the first shield tape; and a jacket that covers the first shield tape, wherein a cross-section of the insulating layer is an oval shape and has a groove at a portion at the first flat portion, wherein the drain wire is retained in the groove such that a portion of the drain wire protrudes toward the first shield tape with respect to the insulating layer, and wherein a twist pitch of twisting together the two-core parallel electric wires is shorter than 250 mm.

  • Publication number: 20210012928
    Abstract: A multicore cable including a plurality of two-core parallel electric wires such that the plurality of two-core parallel electric wires are twisted together, wherein the two-core parallel electric wires each includes two conductors arranged in parallel to a length direction of the two-core parallel electric wire; an insulating layer that covers a periphery of the two conductors; a first shield tape that covers a periphery of the insulating layer in a state of being longitudinally attached to the insulating layer; a drain wire arranged inside the first shield tape; and a jacket that covers the first shield tape, wherein a cross-section of the insulating layer perpendicular to the length direction of the two-core parallel electric wire is an oval shape in which a length of a major axis is 1.7 times or more and 2.

  • Patent number: 10804009
    Abstract: A twinax cable 100 includes a twinax structure, the twinax structure including: a signal wire pair, the signal wire pair including a pair of signal wires formed of a first signal wire and a second signal wire, and an insulating layer configured to cover the pair of signal wires; a drain wire; and a shield tape arranged on the outer circumferential side of the insulating layer to cover the signal wire pair and the drain wire. The insulating layer is mainly composed of polyethylene. The insulating layer includes not less than 30 ppm and not more than 4000 ppm of a hindered phenol-based antioxidant. A dielectric tangent tan ? of the insulating layer at the time of application of a high-frequency electric field having a frequency of 10 GHz is not more than 3.0×10?4.

  • Patent number: 7165701
    Abstract: A nozzle includes a top portion projecting in the same direction as an opening of a container, and a plurality of liquid-medicine passages formed at an outer periphery of the top portion. When the container is inclined, a liquid medicine in the container leaks out therefrom via orifices of the individual liquid-medicine passages communicated with the opening of the container, so as to form a droplet on an outside surface of the top portion, whereby the liquid medicine is applied in a droplet.
