Title: Temperature control of hot-water apparatus
Inventor: KATO SHOZO
IPC: F24D17/00
Filed: 1988-05-11
Abstract: PURPOSE:To improve safety by controlling the supply of hot water above a preset temperature with time, temperature, number of times, or purpose as restrictive factors. CONSTITUTION:To a control device 1A are connected a water flow sensor S1 and a temperature sensor S2 of the hot-water supply both provided to a hot-water supply conduit 2 and also temperature setting devices 8, 9, 10 provided respectively for a bathroom, shower room, and toilet room by a wiring 7. The control device 1A controls the heating by a hot-water apparatus 1 by comparing the temperature signals from the temperature sensor S2 with the signal of a preset temperature: the temperature of the hot water is maintained at a preset point of 80 deg.C until the end of a first prescribed period, and after the passage of the first prescribed period the preset temperature is changed to 60 deg.C and the count of the passage of time is reset. This temperature control secures safety, for example, by supplying hot water at 60 deg.C even if the user subsequently uses a shower 3 without changing the setting of hot-water temperature in the temperature setting device 8 from 80 deg.C. It is also possible to make the temperature control function on the basis of the member of times of the hot-water supply or according to the settings in temperature setting devices for differing uses in one hot-water supply system.

Title: Organic electrolyte battery
Inventor: MORITA TERUYOSHI
IPC: H01M4/58
Filed: 1984-06-04
Abstract: PURPOSE:To improve the ability of the molded electrode to absorb electrolyte and increase the packing rate and the reaction efficiency of the active material by using a mixture composed of proper amounts of a carbon black with a large specific surface area and that with a small specific surface area as the conductive material. CONSTITUTION:A negative electrode 2 is pressed and fixed to the inner surface of a sealing plate 1 and a disk-like positive electrode 4 is installed in a battery case 5. When a carbon black with a large specific surface area is used as a conductive material, a much greater amount of electrolyte is absorbed more rapidly as compared to the case when the same amount of a carbon black with a small specific surface area is used. Therefore a molded electrode with excellent liquid absorption can be obtained by using a conductive material with a large specific surface area. In contrast, when a carbon black with a small specific surface area is used as a conductive material, the molded electrode has great physical strength after it absorbs electrolyte. By the means mentioned above, it is possible to improve the ability of the molded electrode to absorb the electrolyte and to increase the packing rate and the reaction efficiency of the active material.
