Abstract: An exhaust gas purifying apparatus includes an exhaust pipe, a first oxidation catalyst, a selective catalytic reduction (SCR) catalyst, a urea water supply system, a particulate filter (PF) and a controller. Exhaust gas discharged from an internal combustion engine flows through the exhaust pipe. The first oxidation catalyst is disposed in the exhaust pipe. The SCR catalyst is disposed in the exhaust pipe downstream of the first oxidation catalyst. The urea water supply system supplies urea water to the SCR catalyst. The PF is disposed in the exhaust pipe downstream of the SCR catalyst. The controller stops supplying the urea water from the urea water supply system during regeneration of the PF, so as to supply the NO2 formed in the first oxidation catalyst to the PF, wherein the NO2 functions as an oxidizing agent to oxidize particulate matter (PM) deposited on the PF for regenerating the PF.

Abstract: Disclosed is a conventional organic light emitting diode (OLED) having one reflective electrode in combination with at least one transparent OLED in stacked configuration functioning as backlighting in a transflective display apparatus such as a liquid crystal display (LCD). Preferably, at least two transparent OLEDs are arranged in a stacked configuration with one conventional OLED, each of the three OLEDs emitting light of a different bandwidth. The reflective electrode located behind the backlight also serves as a reflecting plate for the display. This arrangement enhances reflectivity and permits color sequencing in the transmissive mode, allowing all the components of a full color display (i.e. red, green, blue) to emit through the same pixel without the need for a color filter.

Abstract: An exhaust gas purifying system is used for purifying exhaust gas discharged from an internal combustion engine installed in a vehicle. The exhaust gas purifying system includes an electrochemical device and a control device. The electrochemical device includes an anode, a cathode and an electrolyte layer disposed between the anode and the cathode. The control device is operable to control the internal combustion engine and the electrochemical device. The control device receives data on condition of the internal combustion engine and controls amount of electric current to be supplied to the electrochemical device based on the data. The data represents amount of exhaust gas. When the control device recognizes that the amount of exhaust gas is increased, the control device increases the amount of electric current to be supplied to the electrochemical device.
