Title: Corrosion inhibitor solid for absorption refrigerating machine
Inventor: MATSUMOTO TORU
IPC: F25B47/00
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent embrittlement for a long period of time to maintain a circulation system of absorption solution in a desired condition by kneading aqueous solution of compound of binder with powder of compound of corrosion inhibitor and heating and drying the mixture thereof. SOLUTION: Diantimony trioxide, as a binder, is mixed with an aqueous solution of lithium bromide, as a corrosion inhibitor, at a weight ratio of 1:1-5 in the form of a paste. The mixture is put into a mold and heated at a temperature of 80-100οC for 20-30 hours and dried to form a strong corrosion inhibitor sold. The solubility of the inhibitor solid is nearly equal to that of conventional one at 70 deg.C; however, at 160 deg.C, the solid exhibits nearly constant solubility for a long period. Further, the conventional inhibitor is embrittled in several tens of hours and formed into a powder, whereas the corrosion inhibitor solid is gradually dissolved from its periphery and not embrittled for more than 1000 hours.  Consequently, the corrosion inhibitor can be supplied to a circulation system of the absorbing solution, where the corrosion inhibitor is consumed, and the system of absorption solution can always be maintained in a good condition.

Title: Power demand forecast method
Inventor: IIZAKA TATSUYA
IPC: G06F17/00
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To automatically estimate the maximum power generation time zone, and to completely automate the maximum power forecast by estimating the time zone for generating the maximum power of a forecast target date by a statistical means, and by using the obtained maximum power generation time zone and forecast weather data for forecasting the maximum power. SOLUTION: The timing when the maximum power is generated is estimated by a statistical analysis. A time zone for generating the maximum power is nearly determined by seasons. Concretely, the time zone for generating the maximum power is different for each region. However, normally, the maximum power is generated at 2-3 p.m. in summer, in the morning or immediately after the sunset m winter, and immediately after the sunset in spring and fall. Also, although the maximum power generation cannot be estimated at the change in seasons, in the case of normal days, the maximum power tends to be generated at the nearly same time as the previous day, thus resulting in procedures for obtaining power demand as in the following. First, the time zone for generating the maximum power is estimated by a statistical means. Then, the weather of the obtained maximum power generation time is used as input information for estimating the maximum power.
