Disclosed is a NOx purifying catalyst which is capable of removing NOx sufficiently efficiently even during operations at low temperatures such as operations in diesel cars. The apparatus has a computer having a microprocessor, a memory storage, a display for providing information to a user, and an input device. The support cage compensates for loss of surface tension of the film in the hot horizontal seal zone during the horizontal sealing cycle. The deactivation or turning off of unused delay stages conserves power at higher frequencies. The system also comprises a third computer system configured to accumulate information from the transaction statement from the plurality of heterogeneous databases. The corner reflector further includes: a canopy that unfolds concurrently with unfolding of the radio wave reflection film, and the canopy is connected to the unfolding device so as to partially overlie the radio wave reflection film.
