Abstract: While an engine (drive source) is being driven, when a long pressing operation (selection operation on a predetermined shift range) on an N-range button via a SBW shifter is executed, an engine drive/stop button blinks to notify a driver (step S1 and step S2). During the blinking of the engine drive/stop button, when the engine drive/stop button is pressed and the engine (drive source) is stopped, a neutral range is maintained without being switched to a parking range automatically (step 3 and step 4).

Abstract: A method and an apparatus which continuously separate and measure mercury in an exhaust gas in accordance with each chemical conformation and display a measurement result in real time. According to the method and the apparatus, water-soluble mercury in a gas is absorbed into an absorption solution (7), the gas and the absorption solution (7) are then separated from each other, the water-soluble mercury in the absorption solution (7) is reduced to be converted into gaseous metal mercury and led to an analyzer (20), and metal mercury in the gas which is not absorbed into the absorption solution (7) is led to an analyzer (22) in the form of gas. As a result, the water-soluble mercury and the non-water-soluble mercury contained in the gas can be captured and measured/analyzed in respective measurement systems in accordance with each chemical conformation. In addition, a concentration of the metal mercury and that of the water-soluble mercury in the gas can be continuously monitored in real time.

Abstract: To provide a method of and an apparatus for continuously measuring elemental mercury and bivalent mercury both contained in a gaseous medium fractionally with a simplified structure, the concentration of a total mercury (Metallic Mercury+Bivalent Mercury) and the concentration of elemental mercury contained in gases are measured continuously and fractionally. In the practice of this mercury measuring method, a first column 1, filled with a first fixed catalyst, and a second column 11, filled with a second fixed catalyst, are fluid connected in parallel relation to each other. The gases G are introduced into those first and second columns 1 and 11. In the first column 1, the first fixed catalyst collects and removes the bivalent mercury, but passes only the elemental mercury in the gases through the first column.
