Abstract: A control device is provided. A key structure of the control device includes a keycap, an optical film layer and a membrane switch. A protrusion structure is formed on the optical film layer or the membrane switch. When the keycap is pressed down by the user, the arrangement of the protrusion structure can facilitate the user to trigger the underlying membrane switch more precisely.

Abstract: An apparatus for automatically but delayedly lifting a toilet seat has a positioning base, a lifting weight and an L-shaped lifting rod. The positioning base is adapted to be firmly secured onto a toilet and includes a short shaft laterally extending therefrom. The lifting weight is a hollow housing including a fore-portion, a mid-portion and a post-portion. The fore-portion is formed with a transverse shaft hole for the short shaft of the positioning base. The mid-portion is formed with a front chamber, and the post-portion is formed with an upper and a lower chamber for containing water or other fluid to create a fluid weight effect. The L-shaped lifting rod is attached at one end to the free end of the fore-portion of the lifting weight and the opposite free end thereof is adapted to inserted between the toilet seat and the toilet. Water can flow among the front, upper and lower chambers to change the lifting torque, so that the toilet seat can be automatically but delayedly lifted by its weight.

Abstract: In a toilet seat and bowl assembly in which the seat rises hydraulically, a toilet bowl has an open-topped seat-receiving portion at one end, an inlet for flushing water at an opposite end and above the seat-receiving portion, a positioning base having a transverse through opening, and a passage for the flushing water from the inlet into the toilet bowl under the seat-receiving portion for flushing the flushing water through the opening, the passage having an upwardly facing, curved bottom surface. A toilet seat apparatus has a toilet seat at one end and a cup connected to the seat by a handle at an opposite end.
