Abstract: PURPOSE:To decompose CO2 produced in a boiler without consuming Mg and HCl used for the decomposition by making the reaction of CO2 and Mg to produce MgO and C, separating and recovering C, changing MgO into MgCl2 for electrolysis, recycling the obtd. Mg by electrolysis for the reaction with CO2, and changing Cl2 into HCl to be used for the reaction to change MgO into MgCl2. CONSTITUTION:CO2 discharged from a boiler 1 is introduced to a CO2 decomposing device 2 where CO2 is made to react with a Mg rod 4 heated by an electric heating device 3 so that CO2 is decomposed into C and MgO. C and MgO are dissolved in the aq. soln. of HCl 5 to recover unreacted C. MgO is made to react with HCl to produce MgCl2 hydrate. The MgCl2 hydrate is treated and changed into MgCl2, which is then electrolyzed in an electrolytic device 6 to be decomposed into Mg and Cl2. Mg is reused for the CO2 decomposing device 2, while Cl2 is reused for the production of HCl. Further, by using midnight power supply for the decomposing device 2 the consumption of electric power is also controlled to the leveling.

Title: Impervious structural material
Inventor: NISHIYAMA KATSUE
IPC: B09B1/00
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent a low permeability material from taking in calcium ions into the interior from the outside and allow a solidification material to exhibit necessary strength by covering constituent granules forming the low permeability material with a capsule that disappears in the process of solidification or after solidification of the solidification material. SOLUTION: A microcapsule 23 is integrated around bentonite 6 by adhering polyethylene glycol 22 to the outside of the mineral crystal of the bentonite 6. This microcapsule 23 is protected so that a chemical change may not occur due to ion exchange between sodium ions in the interior and calcium ions of cement. Cement produces a bozzolan reaction in addition to a central role as calcium ions and the microcapsule 23 melts in water after solidification or in the process of solidification. Thus the disappearance of the microcapsule 23 supplies water molecules to the bentonite 6, and the bentonite 6 contains water and swells, exhibiting imperviousness.

IPC: C21D1/773
Filed: 1987-01-24
Abstract: PURPOSE:To increase the b.p. of a quenching oil and to improve cooling efficiency and hardening characteristics by heating up a work, then immersing the work into an oil tank in a cooling chamber where the atmosphere is pressurized, thereby hardening the work. CONSTITUTION:The work W housed into a heat insulating chamber 12 is heated up by a heater 13 in a heating chamber 2, the inside of which is evacuated to a vacuum by an evacuation system 7. The work W which is thereby heated up to the prescribed hardening temp. is transferred by a carriage mechanism 15. An intermediate door 4 is opened and the work is transferred to a lifting mechanism 9 in the cooling chamber 1, the inside of which is previously evacuated to a vacuum by an evacuation system 6. The door 4 is then closed and the system 6 is stopped. An inert gas such as N2 is introduced from a gas introducing mechanism 10 into the chamber 10 and is fed by a fan 11 to pressurize the atmosphere in the chamber 1 from the reduced pressure state up to the pressure region of about atm. - several atm. The lifting mechanism 9 is lowered in this pressurized state to immerse the work W into the quenching oil O in the oil tank 8. The b.p. of the oil O is increased by the above- mentioned pressurization, by which the vapor film cooling of the work W is quickly shifted to convection cooling. The initial cooling rate is thereby increased and the effective hardening is executed.

CONSTITUTION:Assuming that the mobile body M is in running in frequency f1 at the zone A. The electric field is lowered, which is received at the base station A at the end of zone, and since the code error of the delivery path is increased, the counted number of ''1'' of the measurement 213 for diagnosis series is increased. If this counted value exceeds a criterion, the control station S makes instruction to the peripheral base stations B and C and lets the electromagnetic waves in frequency f1 to receive with the position detection receiver. Further, the control station S compares the average count number of ''1'' of the measurement 219. For example, if the counted number of ''1'' at the base station B is minimized, the mobile body M can be judged that it is transferred from the zone A to B.
