Patent JP-S58124117-A (JP)
Title: Combustion controlling device
Inventor: ASANO YOSHIO
IPC: F23N5/20
Filed: 1982-01-20
Abstract: PURPOSE:To secure energy saving and safeness by a method wherein when ignition is performed by an ignition timer, combustion is interrupted by an electronic timer after a certain period of time elapses. CONSTITUTION:When a switch of the ignition timer 3 turns ON after a preset time period, preheating and ignition start. At the same time, the light emitting side 18a of a photocoupler and another light combining element 18b on the light receiving side 18b of the photocoupler are supplied with electric current via contact 2-1 and 7-9 respectively. Thus Hi signal is inputted into a start signal terminal of the electronic timer 19 to start the time counting of the timer 19.  On the other hand, an output signal at an output terminal (b) has been Lo from  before the start of the timer 19 and continues to be Lo for a certain time period  after the timer 19 starting. Then the output signal at the output terminal (b)  becomes Hi, so that a transistor 22 turns ON. Accordingly, another transistor 15  turns OFF to interrupt the current supply to a relay 16 so as to open a normally-opened contact 16a and also interrupt the current supply to a motor 9 of a  combustion air fan and the like so as to stop the combustion.

Abstract: PURPOSE:To electrolytically produce fluorine stably for a long period of time with high productivity by electrolyzing a fused salt mixture bath essentially consisting of KF and HF and executing the electrolysis by using a carbon or graphite anode having a specific surface layer consisting of C, F and metal. CONSTITUTION:The fused salt mixture essentially consisting of the KF and HF is used as the electrolytic bath and the fluorine is obtd. by the electrolysis. The carbon or graphite electrode having the surface layer of the compsn. expressed by the general formula CxMyFz (where M: group II metal or the periodic table or mixture composed of group I and/or III metals, x; integer in the range of 90-160, y; integer in the range of 2-8, z; integer in the range of 8-20) on the surface is used as the anode of this time. This anode can be formed by allowing the above-mentioned M to coexist in the above-mentioned electrolytic bath and executing the electrolysis by using the carbon or graphite electrode while energizing the same at the alternately switched inter-electrode polarities. Generation of an anode effect is thereby prevented over a long period of time and the electrolytic production of the fluorine is executes stably over a long period of time with less energy consumption and high productivity.
