  • Patent number: 11950503
    Abstract: An organic material represented by General Formula (1): where, in General Formula (1), R1 is an alkyl group having 6 carbon atoms or more but 20 carbon atoms or less; n is an integer of from 1 through 3; X1 to X4 are each a hydrogen atom or a fluorine atom; and Z is a compound represented by General Formula (2), (3), or (4) below: where, in General Formulae (2) to (4), R2, R3, and R4 are each an alkyl group having 6 carbon atoms or more but 20 carbon atoms or less; and Y is an oxygen atom or a sulfur atom.

  • Patent number: 9221462
    Abstract: A vehicle behavior stability control apparatus includes a yaw rate sensor, a lateral acceleration sensor, a vehicle speed sensor, an urgency determining section, a target yaw rate setting section, and an actuator control section. If the urgency determining section determines that an urgency with which a vehicle behavior is to be stabilized is equal to or lower than a determination criterion that indicates a necessity to stabilize the vehicle behavior urgently, the target yaw rate setting section sets, as a target yaw rate, a right-left cooperative target yaw rate that is commonly applied to both right cornering and left cornering. Otherwise, if the urgency determining section determines that the urgency exceeds the determination criterion, the target yaw rate setting section sets, as a target yaw rate, right-left independent target yaw rates that are independently applied to the right cornering and left cornering, respectively.
