Title: Method and apparatus for improving ground
Inventor: YAMASHITA GIICHI
IPC: E02D3/08
Filed: 1985-04-22
Abstract: PURPOSE:To uniformly and precisely improve the ground by a method in which powdered quick lime columns formed through casing pipes under the ground are mixed with soil by stirring blades to harden the whole area of the ground. CONSTITUTION:The stirring blades 24 of a stirrer 25 are penetrated into the ground 1 while being turned, and casing pipes 2 are penetrated into the ground 1. Quick lime 5 is then packed into the pipes 2, and when the blades 24 and the pipes 2 are raised, covers 7 are opened and the quick lime columns are left under the ground 1. Whereupon, the quick lime columns are mixed with soil by the blades 24 being turned while rising from below to above, and the quick lime and soil mixture absorbs groundwater in the ground uniformly to cause slake lime reactions which harden the ground 1. The ground can thus be uniformly and precisely improved over the whole area.

Title: Hydrogen fuel power generating system
Inventor: KAWAKAMI AKIO
IPC: H01M8/00
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To generate an electric power demand during a midnight time period when the electric power demand is little while to suppress the electric power demand in the daytime when the electric power demand is much. SOLUTION: Midnight power is supplied from a distribution panel 12 for midnight power during only a predetermined midnight time period. A controller 66 converts the midnight power into a DC to supply it to an electrolytic cell 18 when a pressure sensor 38 detects a hydrogen pressure lower than a target value during the midnight time period. The electrolytic cell 18 supplies the DC between electrodes 22, 24, to electrolyze water into hydrogen. The hydrogen discharged to a negative electrode side air chamber 20A inside the electrolytic cell 18 is compressed by a compressor 30, to be filled in a hydrogen storing tank 36. In a fuel cell device 42, the hydrogen supplied from the hydrogen storing tank 36 is reacted with oxygen in the air, thereby generating electric energy corresponding to an outside load.

IPC: C02F9/00
Filed: 1991-03-25
Abstract: PURPOSE:To obtain fresh water (ultra-pure water) by noticing that a b. p. falls on dropping of the atm. pressure, heating the sea water or polluted water with a solar heat absorbing plate or electric heating plate to accelerate the generation of steam as the b.p. falls rapidly near the vacuum, sucking the steam with a vacuum pump, cooling the steam with a cooler and passing the water through an ion exchange resin in order to remove impurities. CONSTITUTION:The water is first sucked up by a water feed pump 1 and the sea water or polluted water deaerated by a deaerator 2 is put into a cylinder evacuated nearly to the vacuum. The water is then heated by the solar heat absorbing plate 3 or the electric heating plate 8, by which the temp. is raised. Since the b.p. is low, the water can instantaneously be evaporated. The generated steam is sucked by a vacuum pump 4 and is accumulated in a steam accumulator 5. The steam is cooled with the cooler 6. The fresh water (ultra-pure water) is obtd. if the impurities intruded into the water are removed by the ion exchange resin.
