    Abstract: An absorbent article (1) of the present invention includes a leg cuff (24). The leg cuff (24) has leg elastic members (25). The leg cuff (24) can be divided, by an imaginary line (IL) passing through the center (ct) between an outermost leg elastic member (25s) that is located farthest outward and an innermost leg elastic member (25i) that is located farthest inward, into a leg cuff first region (ST) that extends from the imaginary line (IL) up to and including the outermost leg elastic member (25s) and a leg cuff second region (IT) that extends from the imaginary line (IL) up to and including the innermost leg elastic member (25i). When the elongation amount of the leg cuff first region (ST) and the leg cuff second region (IT) in a natural state is defined as 0, and the elongation amount thereof in a maximally stretched state is defined as 100, the stress in the leg cuff first region (ST) is greater than the stress in the leg cuff second region (IT) when the elongation amount is 5.

  • Patent number: 8616061
    Abstract: An ultrasonic sensor includes a transmitting device, a receiving device, and a circuit device. The circuit device determines that the receiving device receives an ultrasonic wave reflected from an object, when an output voltage of the receiving device is equal to or greater than a first threshold. The circuit device includes a humidity detection section configured to detect an ambient humidity of the transmitting and receiving devices and a threshold adjustment section configured to calculate, based on the detected ambient humidity, a sound pressure of the ultrasonic wave that is received by the receiving device after propagating over a round-trip distance between the ultrasonic sensor and the object.

  • Patent number: 8503265
    Abstract: A transmission and reception device is located at a predetermined height on a movable object and directed toward an outside. The transmission and reception device includes a transmission unit for repeatedly transmitting sensing waves at a predetermined interval and a reception unit for receiving reflective waves of the sensing waves from a detected object. A peak value detecting unit detects peak values of the received reflective waves and stores the detected peak values. A difference arithmetic unit calculates a difference in the detected peak values with movement of the movable object closer to the detected object. An object determination unit determines the detected object to be a near-road-surface obstacle, which is close to a road surface, when the difference is a negative value. The object determination unit determines the detected object to be an other obstacle than the near-road-surface obstacle when the difference is a positive value.
