Abstract: An improved structure of electric lock disclosed herein employs only one electromagnetic coil and a DC power source formed of 4 3A-type dry battery unit for operating the lock instead of using two coils and an AC large power source along with a clumsy conductor layout, and a skilful arrangement of mutual positions between the driven rod and the extended portion of the actuated rod can produce an amplified driving torque effect from this minimized DC power source. Besides, the key function is controlled by a coded chip attached thereon to identify the visitor.

Abstract: An electronic chip functioned lock whose tongue piece revolving mechanism is either manually operatable with a mechanical key, or by an electronic chip attached key. The lock mechanism is connected to a computer for reading input information to confirm the code stored in the chip so as to avoid unauthorized entry, and to amend, store, or erase the data in case of need. The computer can further be interconnected to a local security system.

Abstract: Disclosed is a heeling-in and transplating means for easy inducing and cutting roots comprising a culturing bag and being characterized in that the culturing bag is provided near a middle portion a partition which guides roots of a plant heeled in the culturing bag to grow and extend evenly and radially above the partition and then downward along an innner periphery of the culturing bag, a plurality of water-soluble root-inducing nutrient stripes attached to the inner periphery of the culturing bag below the partition, and a plurality of externally communicable eyelets provided at a lower portion of the nutrient stripes for guiding and cutting roots. When the culturing bag is to be used, first position it in a planting hole on the ground, and the partition is lifted to facilitate the filling in of culture medium. Then, the partition is lowered again and more culture medium is filled in the bag to an adequate thickness.

Abstract: A bicomponent tissue and seedling culture bottle includes an upper cover portion having an opening facing downward, and a lower container portion having a closed base and suitable for fitly but detachably connecting to the downward opening of the upper cover portion, characterized in that, a T-shaped air vent consisting of a vertical air passage centered at a top portion of the upper cover and two horizontal air passages symmetrically located at and extending from two opposite sides of the vertical air passage to be communicable with the outside air, so that air or gas produced in the culture bottle during the culture process can escape from the air vent and germs or viruses can be prevented from entering into the culture bottle when the seedlings are matured and/or are transplanted and the survival percent of the bottle cultured seedlings can be raised.
