Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

PROBLEM TO BE SOLVED: To provide a coastal zone fertilizing system which contributes to recovery of a bioenvironment by making effective use of iron fulvate and ocean deep water.

SOLUTION: According to the system an organic acid iron salt is added beforehand to a driving fluid for driving a fluid jet pump constituting a deep water pumping device, by a constant quantity feeder of the organic acid iron salt, and the deep water pumping device functions to pump and feed deep water by the driving fluid, followed by sucking and agitating the deep water and peripheral surface water discharged toward an intake port of a deformed inverted U-shaped pipe type distributive water feeder. In this manner the agitated water is discharged from a water discharge port arranged on a seabed in the coastal zone again via the distributive water feeder, and therefore the novel coastal zone fertilizing system is realized.

PROBLEM TO BE SOLVED: To provide a method for reducing nutrient salt concentration in brine utilizing a marine alga, and a system as well as its apparatus.

SOLUTION: The method for reducing the nutrient salt concentration in the brine uses an immature unialgal culture strain which a marine alga sporophyte has grown up into or the alga body in which the immature unialgal culture strain has propagated introduced to its apparatus. The marine alga sporophyte originates from a specified large-sized red marine alga, for example, the Gracilaria species having the following properties: (1) a matured female gametophyte in nature is not found, (2) a matured form of only a tetrasporophyte is found, (3) it grows in an area of natural marine water mixed with fresh water.

PROBLEM TO BE SOLVED: To provide a nutrient salts concentration reducing apparatus, a system, and a method for reducing the concentration of nutrient salts in salt water.

SOLUTION: In the nutrient salts concentration reducing apparatus, each of reducing units with different heights has a seaweed cultivation section for absorbing the nutrient salts; each of the reducing units other than the units at the lowest position among the multiple reducing units has a siphon pipe and a switching device; the reducing unit at the lowest position is connected to at least one of the multiple reducing units other than the unit at the lowest position via a circulation pump and the switching device; salt water can be sent from the higher reducing unit to the lower reducing unit; and salt water can be sent from the reducing unit at the lowest position to at least one of the reducing units other than the reducing units at the lowest position.

PROBLEM TO BE SOLVED: To provide a new nutrient salts concentration reducing apparatus, system, and method for reducing the concentration of nutrient salts in salt water.

SOLUTION: A plurality of nutrient salts concentration reducing units U1-U8 having a seaweed culture part are arranged at different heights, and salt water is fed from a higher-located reducing unit to a lower-located reducing unit through a siphon tube, allowing the salt water to be smoothly fed without using a liquid feeding means such as a liquid feed pump. The heights of the plurality of the reducing units U1-U8 are changed at a predetermined timing, and the passages of the salt water are switched at the predetermined timing, enabling a more efficient reduction of the nutrient salts concentration. By using special kinds of seaweed as the seaweed, or by retaining the seaweed on special gel and/or fiber, the efficiency of reducing the nutrient salts concentration is further improved.
