  • Patent number: 11634639
    Abstract: A polarizing film including a polarizer that is a cured product of a polymerizable liquid crystal composition is provided. The polymerizable liquid crystal composition contains both a polymerizable liquid crystal compound having at least one polymerizable group and a dichroic coloring matter. The polarizer is laminated on a surface, having a pore size of 0.45 nm to 0.57 nm, of a base material. The pore size is obtained by converting, into a diameter, an average free volume radius calculated by a positron lifetime measurement method in which the positron lifetime is measured by irradiating the surface with positrons with an injection energy of 3 kV.

  • Patent number: 11196049
    Abstract: Provided are excellent coated lithium-nickel composite oxide particles with which it is possible, due to the high environmental stability thereof, to minimize the incidence of impurities owing to absorption of moisture and carbon dioxide gas, said particles having high adhesiveness such that the coating layer does not easily delaminate, and having lithium-ion conductivity. The coated lithium-nickel composite oxide particles, in which an electroconductive polymer is cross-linked to the lithium-nickel composite oxide particles by a three-dimensional structure, are electrically and ionically conductive, and the compound is capable of suppressing the transmission of moisture and carbon dioxide. It is therefore possible to provide coated lithium-nickel composite oxide particles for a lithium-ion cell positive-electrode active substance that is excellent for use in a lithium-ion cell.

  • Publication number: 20200062150
    Abstract: A seat assembly includes a seat cushion frame, a seat back frame, a bracket, a pin actuator, a sensor, and an electronic control unit. The seat back frame is pivotally connected to the seat cushion frame about a pivot axis. The bracket is fixed to the seat cushion frame. The bracket includes a cam surface, and a distance between the cam surface and the pivot axis varies along the cam surface. The pin actuation includes a pin. The pin actuator is fixed to the seat back frame. The pin actuator is configured to move the pin from a disengaged position to an engaged position. The electronic control unit determines whether the sensor detects the front collision of the vehicle and controls the pin actuator to move the pin from the disengaged position to the engaged position.

  • Patent number: 10439214
    Abstract: To provide excellent lithium-nickel composite oxide particles which have high environmental stability and are thus capable of suppressing generation of impurities due to absorption of moisture and a carbon dioxide gas, while being prevented from easy separation of a coating film because of high adhesion thereof and having lithium ion conductivity. Coated lithium-nickel composite oxide particles, which are obtained by coating the surfaces of lithium-nickel composite oxide particles with a predetermined coating material, have electrical conductivity and ion conductivity and are capable of suppressing permeation of moisture and a carbon dioxide gas. Consequently, the present invention is able to provide coated lithium-nickel composite oxide particles for positive electrode active materials of lithium ion batteries, which is excellent for use in lithium ion batteries.
