Title: One-boiler two-circuit type hot water supply equipment
Inventor: TANAKA YOSHIHIKO
IPC: F24H1/00
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of noise of a blower fan by changing the number of revolutions of the blower fan from the number of revolutions in a combustion operation to that for ignition in the case when the operation of a burner is once turned OFF in the operation of equipment and by making the fan stand by during an OFF period. SOLUTION: When operation is started, a control part 70 computes a necessary combustion heat quantity from a set heated water temperature, an incoming water temperature from an incoming water temperature sensor, the quantity of incoming water from a water quantity sensor 51, etc., and executes an FF control, using the combustion heat quantity as an FF control value. Then it executes an FB control, using a combustion heat quantity corresponding to a difference between an actual heated water temperature and the set heated water temperature as an FB control value.  When a general hot water faucet 43a is closed and consequently the quantity of water detected by the water quantity sensor 51 becomes the lowest operating water quantity or less in the course of a hot water supply operation, the control part 70 turns OFF combustion of a burner 12 by stopping supply of fuel, while it changes the number of revolutions of a blower fan 11 from that in the combustion to that in post-purge and further stops the rotation of the blower fan 11 after a prescribed post-purge time passes. Thereby the operation is ended.

Title: Non-aqueous secondary battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M10/052
Filed: 1990-08-09
Abstract: PURPOSE:To enhance the cycle characteristic of a non-aqueous secondary battery by preparing Li-containing Mn oxide used for pos. electrode active substance so as to have a specific surface area of 9.0-6.7m<2>/g as measured by BET method. CONSTITUTION:Mn oxide containing Li used to a positive electrode 7 has a specific surface area which becomes smaller than that of MnO2 as crude material when mixture of Li salt and MnO2 is subjected to heat treatment, depending upon the sort of MnO2 as material, share of Li content, heat treatment temp., etc. The specific surface area of this L-containing Mn oxide measured by BET method is restricted to 9.0-67.5m<2>/g, but a further restriction tot the range 9.0-61.5m<2>/g gives a proper specific surface area to enhance the charge/discharge cycle characteristic and provide a large discharge capacity as well as high endurance against overcharging. Selecting the particle sizes of the Li-containing MnO2 to under 20mum accomplishes uniform reactions of Li salt with MnO2, and remaining of a portion out of reaction can be suppressed. If the particle sizes of Li-containing MnO2 is below 20mum after the pos. electrode has undergone pressurized molding, Li can disperse evenly in the Mn solid phase, and movement of Li be suppressed during charging and discharging. Thus an enhanced cycle characteristic is obtained.
