    摘要: An apparatus and a method of analyzing constituents of gas in an oral cavity and exhaled breath is disclosed. The apparatus for analyzing the constituents of gas in the oral cavity and exhaled breath according to the present invention includes a filter to filter the outside gas by adsorbing polar molecules and non-polar molecules in the outside air and by removing water in the outside air in order to use the outside gas as carrier gas. The apparatus can also include a plurality of solenoid valves for controlling the flow of a carrier gas; a sensor for detecting components of the exhaled breath; a pump to draw the gas in the oral cavity or the exhaled breath and the carrier gas and discharge the gases to the outside; a control unit for controlling the components of the apparatus; and a display device to display results calculated by the control unit.

    摘要: A transmission device for farm tractors is disclosed. In the transmission device, a hollow travelling drive shaft and a PTO drive internal shaft are substituted for a typical hollow PTO drive shaft and travelling internal shaft, respectively. The transmission device also has a splined flange for directly transmitting the engine power from the flywheel to the PTO drive internal shaft. In a main change gear unit, a hub sleeve and a main gear shifting shaft are forged into a single structure. A super low-speed change gear unit is connected to a sub-change gear through two sets of shafts capable of allowing the super low-speed change gear unit to be independently operated from the sub-speed change gear unit. The transmission device is thus selectively operated without performing any super low-speed changing action.
