    Abstract: A gas-liquid separator includes a housing (10) being supplied with water-containing gas, a gas-liquid separation portion (3) being provided inside the housing (10) and separating water from water-containing gas, a water storage portion (5) being arranged on a bottom portion of the housing (10) and storing water separated by the gas-liquid separation portion (3), and a valve mechanism (6) enabling discharge of and stop of the discharge of water in the water storage portion (5) via a discharge flow path (18a) communicating with the water storage portion (5). An inner wall of the housing (10) has a guide surface (4) flowing water toward the water storage portion (5) and is provided with a regulating portion (25) regulating staying of water in a vicinity of a flow-in port of the discharge flow path (18a).

    Abstract: A road surface condition estimation device (200) includes a control circuit (201), an acquisition circuit (202) and an estimation circuit (203). The control circuit (201) is configured to control a driving device that is able to independently drive a plurality of wheels. The acquisition circuit (202) is configured to acquire detection results of a plurality of wheel speed sensors that detects rotation speeds of the plurality of wheels respectively. The estimation circuit (203) is configured to calculate a slip ratio for each driving wheel, based on a detection result of a first wheel speed sensor and a detection result of a second wheel sensor. The estimation circuit (203) is configured to estimate a friction coefficient for each region on a road surface that corresponds to the driving wheel, based on the slip ratio.

    Abstract: A vehicle seat device includes: a base member (32, 33) provided in a seat cushion (2, 102) or a seat back (3, 103); a movable member (33, 34) rotatably connected to the base member; and stopper parts (56, 57) disposed to abut against each other on the base and movable members. The movable member rotates from a storage position and the rotation of the movable member is restricted at a deployment position so that a seat mode is changed. The vehicle seat device further includes an air bag interposed between the base and movable members and presses the base and movable members to rotate the movable member; and a clutch mechanism (55, 65) interposed between the base and movable members, allowing the rotation of the movable member in a deployment direction, and restricting the rotation of the movable member in a storage direction.
