Abstract: A flowerpot employs a water reservoir in its bottom section, a soil holding section above the water reservoir, a porous water/soil separation board which separates the water reservoir and the soil holding section, and a pot cover. Any excessive water in the water reservoir can escape to the outside through an overflow water escape facility. The porous water/soil separation board holds the soil thereon and allows any moisture or water to pass therethrough. The pot cover collects dews and rainwater and keeps the moisture in the pot from escaping to the outside by evaporation. Namely, the flowerpot is a planting system which has automatic water preserving, drainage, and recycling facilities.

Abstract: An automatic roadside multi-storied parking system including collapsible parking racks each having a plurality of vertically spaced parking platforms and between each two parking racks a lift conveyer capable of ascending and descending stepwise to reach the level of each parking platform. The parking system is also equipped with an emergency ladder on one side of each rack for a person to climb up or down during an emergency. A wheeled moving device is provided on the bottom of each module of the system to assist in adjustment of the angle and direction of the individual modules and is spring-released to flip into a storage recess for the stability of the modules. Parking racks and lift conveyers are fitted and supported each on both sides thereof with lazy tong-type links and oil cylinders are provided for lifting and unfolding of the parking racks and for raising and lowering of the lift conveyer to or from the level of a selected parking platform.
