Abstract: A process for preparing a moisture exchange element which comprises impregnating a substrate made of organic or inorganic fiber with an aqueous impregnating solution containing colloidal silica, an acid and a metallic cation; drying and gelatinizing the impregnating solution deposited on the impregnated substrate is disclosed. The absorbent formed on the substrate after the impregnating solution is dried has a pore size of about 60-70 .ANG., thus allowing the moisture exchange element of the present invention to provide improved moisture adsorbing/desorbing ability.

Abstract: A device to remove the pod peanuts from the root thereof. The device mainly comprises a stem and leaf conveying mechanism and a pod peanut rubbing and conveying mechanism. The two mechanisms hold the stem and leaf portion and the pod peanut portion respectively, and twist the two portions simultaneously so as to cause the pod peanuts to separated from the root of peanut plant. The stem and leaf conveying mechanism includes a sliding member and a driving member; the pod peanut rubbing and conveying mechanism includes a fixed rubbing member and a rotary rubbing member. Both of the two mechanisms are driven with a driving power so as to provide almost an equal conveying speed for the stem and leaf portion and the pod peanut portion.

Abstract: A safe and simple fuse replacement device whereby facile exchange of fuse can be achieved by means of the introduction of the replacement fuse onto a tripper that will jump outwards as it is subjected to elastic pressure transferred by a spring mechanism.

Abstract: The automatic trap for catching cockroach mainly includes an automatic control mechanism. As cockroaches enter into the trap, they will inevitably touch a switch of said automatic control mechanism to drive a slipping plate forward and further to automatically sweep these cockroaches into a confinement cell. After that, the slipping plate will be also automatically back to its original position, restoring the control function of the automatic control mechanism, which is the particularly advantageous feature of the present invention.

Abstract: The present invention is to provide an automatic animal-trapping device, more particularly, to provide a kind of animal-trapping device, used for trapping mice and other like wild animals, which may repeat its operating cycle all over again and catch lots of mice in continuity with special functions of its automatic control mechanisms.
