    摘要： A watersports sandal is disclosed. The sandal has a flexible sole that underlies and protects a user's foot in a walking configuration. The sandal has a detachable forefoot strap that connects the sole to the user's forefoot and an ankle strap that connects the heel portion of the sole to the lower leg of the user. The sandal can be reconfigured to a stowed configuration in which the forefoot strap attaches the sole to a user's lower leg. In this stowed configuration, the user's bare feet are exposed to allow him fine sensitivity to water sport devices such as surf boards.

    摘要： A cleaner for magnetic heads of tape recorders includes two gears centrally engaged with the revolving shaft of the recorder during use and pivotally installed in two revolving shaft holes on the tape cartridge respectively and peripherally engaged with each other. A plurality of projecting posts are spaced equally along the circumference in the planes of the two gears and alternately disposed in respect of each other post. A rocker is centrally and pivotally installed nearby the front end of tape recorder and between the two gears. Two opposite contact legs are provided to the rear end of the rocker and projected toward these posts respectively so as to contact these post alternately and respectively, and a cleaning element is installed on the front of the rocker. When this cleaner is installed in the tape recorder for use, the two gears rotate synchronously in opposite directions, the posts push and swing the rocker left and right alternately and respectively in sequence, so the rocker swings left and right and the cleaning element of the front end of rocker can clean the magnetic head of the recorder.

    摘要翻译： 磁带录音机的磁头清洁器包括两个齿轮，它们在使用过程中与记录器的回转轴中心配合，并分别枢转地安装在磁带盒上的两个旋转轴孔中，并且彼此周向接合。 多个突出柱沿着两个齿轮的平面中的圆周相等间隔，并且相对于每个其他柱交替布置。 摇杆在磁带录音机的前端附近和两个齿轮之间居中枢转。 两个相对的接触腿分别设置在摇臂的后端并分别向这些支柱突出，以交替地分别接触这些柱，并且清洁元件安装在摇杆的前面。 当该清洁器安装在磁带录音机中时，两个齿轮沿相反方向同步旋转，柱按顺序分别左右摇动摇杆左右旋转，摇杆左右摆动，清洗元件 摇杆的前端可以清洁录音机的磁头。
