Abstract: A lead-acid battery (100) is provided with a lid (14). An external flow passage (530) communicating with a communication chamber (520) through a vent hole (321) and communicating with a discharge port (405) of a lid (14) is formed inside the lid (14). A compartment fence (452, 454) continuously extending over the entire width of the external flow passage (530) is formed in the external flow passage (530). A residual volume is larger than the volume of the communication chamber (520), the residual volume being obtained by subtracting, from the total volume of a plurality of external spaces (460, 462, 464) divided by the compartment fence (452, 454), the volume of the discharge-side external space (464) closest to the discharge port among the plurality of external spaces.

Abstract: A liquid crystal lens includes a first electrode including a first electrode portion having a circular opening and a second electrode portion arranged on an inner side of the opening, a second electrode opposed to the first electrode, a liquid crystal layer formed between the first electrode and the second electrode, and power supplies configured to apply an AC voltage to the first and second electrodes. The power supplies include a first power supply configured to apply a first rectangular wave voltage to the first electrode portion, a second power supply configured to apply a second rectangular wave voltage with a phase identical to that of the first voltage to the second electrode portion, and a third power supply configured to apply a third rectangular wave voltage with a phase different from those of the first and second voltages by 180° to the second electrode.

Abstract: A vehicle seat includes a seat cushion that is rotatably joined to a floor portion of a vehicle such that a rotation axis of the seat cushion extends vertically, the seat cushion being configured to support a buttocks of a seated vehicle occupant. The vehicle seat also includes a footrest that is joined to the seat cushion and is configured to support soles of feet of the seated vehicle occupant, the footrest being placed in a raised position in which, when seen in a seat side view, the footrest slopes rearwardly upwards such that heels of the seated vehicle occupant are raised up, and a rear portion of the footrest is placed vertically below a front end of the seat cushion.

Abstract: In a vehicle seat, a seat cushion is coupled to a floor section of a vehicle so as to swivel about a vertical axis. When the vehicle seat swivels about the vertical axis from a forward-facing position to a rearward-facing position, a seatback of the vehicle seat is swiveled about a horizontal axis extending in a seat width direction by a first swivel mechanism from a first upright position (while in the forward-facing position) toward the seat front side so as to be disposed in a second upright position that is inclined forward relative to the first upright position (while at a position between the forward-facing position and the rearward-facing position), and then is swiveled from the second upright position toward a seat rear side (while in the rearward facing position).
