Abstract: The present invention relates to an electrolyzer for producing sodium hypochlorite by electrolyzing brine such as salt water or seawater and the like, and more specifically to a horizontal non-membrane type electrolyzer of a new structure which can maintain a constant interval among electrode plates without using a welding means or an adhering means on the inside of a housing by including a separator for dividing an inner space of a hollow type housing into a plurality of electrode chambers; the electrode plates which are arranged in parallel to each other in the constant interval within a rectangular space part of the separator; and a fixing bar for fixing the separator to an inner wall of the housing.

Abstract: A lower limit of a heating factor for heating control of an oxygen sensor is adjusted on the basis of the heating factor, a P-jump delay time calculated based on an output voltage of the oxygen sensor, and a diagnosis index of the oxygen sensor, and thereby an engine may be stably controlled even if the oxygen sensor is aged.

Abstract: Disclosed is a method for manufacturing a catalytic oxide anode using high temperature sintering, which can increase a decomposition efficiency of an organic substance by improving a performance of the catalytic oxide anode (Ru oxide anode, Ir oxide anode) used in a water treatment, and in particular, to a method for manufacturing a catalytic oxide anode, in which the oxide anode is sintered at 600° C. or higher, and a TiO2-screening layer is formed between a titanium base metal and a catalytic oxide layer to prevent a lowering of the oxide anode activity owing to an oxidation of the titanium base metal caused by sintering the oxide anode at high temperature and a solid diffusion of an oxide into an anode surface.
