    Abstract: An optical pickup device includes: a first partition wall defining two housing portions inside a housing, and including a through-hole penetrating from a first principal surface to a second principal surface of the first partition wall; a light-emitting element holder holding a light-emitting element, including an opening through which a light beam from the light-emitting element passes, a portion of the holder surrounding the opening being in contact with a portion of the first principal surface surrounding the through-hole; and a diffraction grating whose peripheral portion is in contact with a portion of the second principal surface surrounding the through-hole. In the device, the light-emitting element holder, the first partition wall, and the diffraction grating together form a closed space, and an optical path of the light beam from a light-emission point of the light-emitting element to the diffraction grating is inside the space.

    Abstract: A vehicle seat comprises a cushion plate mounted on upper and lower seat springs, a seat cushion provided on a front side of the cushion plate, an auxiliary plate provided between the seat cushion and the cushion plate for pushing out the seat cushion forward. The cushion plate includes an upper plate located higher than the lower seat spring and a lower plate located lower than the lower seat spring. The lower plate has such elastic force that when the lower plate receives, through the seat back cushion, pressure from a person properly seated on the seat, the lower plate can move backward by a greater distance than the distance of rearward movement of the lower seat spring.

    Abstract translation: 汽车座椅包括安装在上座椅弹簧和下座椅弹簧上的缓冲板，设置在缓冲板前侧的座垫，设置在座垫和缓冲板之间的辅助板，以向前推出座垫。 缓冲板包括位于比下座椅弹簧高的上板和位于下座椅弹簧下方的下板。 下板具有这样的弹性力，当下板通过座椅靠背垫接受来自正确坐在座椅上的人的压力时，下板可以向后移动比下座的向后运动的距离更大的距离 弹簧。
