摘要:
The present invention is to prevent a drop in the detection accuracy caused by wear of the central shaft of a frame where a magnet holder and the magnet are fitted to each other in the course of prolonged use. A contactless liquid level sensor includes: a magnet holder which includes a resin holder body having an inner circumferential surface for defining a fitting hole and a magnet accommodated inside the holder body along the inner circumferential surface; a resin frame including a frame body, a central shaft protruding from the frame body, and a magnetic-electric converter accommodated inside the central shaft; a float arm including one end fixed to the magnet holder and the other end attached to a float vertically moving in accordance with a liquid level; and a metallic rotary support including a hollow cylindrical part arranged between the inner circumferential surface of the holder body and an outer circumferential surface of the central shaft. When the magnet holder rotates about the central shaft in accordance with the liquid level, a magnetic flux density passing through the magnetic-electric converter is varied thereby detecting a variation in the liquid level.

A greening system us disclosed for enabling plants/vegetation to grow only with natural rainfall, without any particular irrigation facilities, enabling a full-blown garden to be constructed on building rooftops, minimizing the applicable loads on the building, and free from the risk of leakage. Planting container 1 comprises box 2 with stickers 3 to carry perforated partition panel 4. The lower half of the container is constituted as water storage 5, and drain holes 6 are opened on sides of the container. Soil layer 7 placed on partition panel 4 is formed of light woody soil-based on charcoal 9 and humus timber chips for absorbing moisture transported from the water 8 stored in water storage 5 by evaporation or difference in humidity, to have a large water capacity letting less water evaporate into the air. Charcoal 9 absorbs water from the air inside the lower half of the container to water the plants. Water storage 5 assures an amount of water necessary for plants to grow.

摘要:
A contact is provided for a fluid level detection apparatus. The contact includes a contact support spring for rotating in response to a change in fluid level. The contact support spring includes a cantilevered spring arm having a proximal end to be fixed to a holder and a free end, and a contact support which is provided at the free end. First and second contacts are attached to the contact support in first and second positions, respectively, the first position being set at one end opposite to an end at which the second position is set. The joining position of the contact support and cantilevered spring arm is set so that a pressing load applied to the first and second contacts on the contact support by the flexure displacement of the contact support spring falls within a predetermined range.
