Title: Water treatment apparatus
Inventor: YAMAGUCHI YOSHIO
IPC: C02F1/46
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To certainly suppress the propagation of bacteria in stagnated water in a filter material or residual water in a main body over a long period of time, in a water treatment apparatus equipped with a filter material, by providing a means for supplying silver ions due to an electric field and a control means for controlling the electrolytic quantity of silver on the upstream side of the filter material. SOLUTION: A silver ion supply device 1 is arranged on the upstream side of a water purifying catridge 10 to continuously or intermittently add silver ions to supplied water. The silver ion supply device 1 is constituted as a supply device due to the electrolysis of silver and a silver electrode 6 being an anode and an insoluble electrode 7 being a cathode are arranged to a silver dissolving tank 8. Therefore, if a current is supplied to both electrodes 6, 7 at every predetermined time, silver ions can be supplied to supplied water. At this time, the current value supplied to both electrodes 6, 7 through a current value control device 30 is controlled on the basis of the flow rate signal from the flow rate counter 5 by a supply control device 3.  By this constitution, the propagation of bacteria in residual water in the filter material etc. housed in the water purifying cartridge 10 is certainly suppressed.

Title: Imperfect burning detection device
Inventor: TAKEMURA HIDEO
IPC: F23N5/08
Filed: 1984-07-11
Abstract: PURPOSE:To detect abnormal burning by disposing a detection circuit that detects imperfect burning condition by output signal from a photoreceptor element that catches the radiation light from a red-hot body. CONSTITUTION:Vaporized fuel is mixed with air in a hollow space between an outer flame tube 2 and an inner flame tube 3, and rises at it is burnt. As a red- hot body 6 which is disposed at the upper end of the outer tube 1 and is made with a rod in a Z-shape that consists of heat-resistant metal emits radiation light at a higher intensity than the burning flame 5 around it, the photoreceptor element 4 receives the light mainly from the red-hot body 6. When oxygen becomes defficient under such a condition, the flame intensity of burning wanes by the burning mechanism which is intrincic to the natural vaporization type burning apparatus, the calorific value to heat the red-hot body 6 deminishes. As a result, the radiation light from the red-hot body 6 decreases as the temperature of the red-hot body 6 decreases, and the spectrometric characteristics of light deviates to the side of a longer wave length. Therefore, by catching such a change by the photoreceptor element 4, an abnormal burning due to the oxygen defficiency can easily be detected even in a natural vaporization type burning apparatus.
