A moisture adsorbent for adsorbing moisture in exhaust gas and an NOx adsorbent for adsorbing NOx are disposed in a bypass passage for bypassing an exhaust passage of an internal combustion engine. The display device detects a shadow of the object, which is projected on the display panel when the object approaches the display panel and blocks ambient light, with a photosensor, whereby a position or motion of the object is detected. The amorphous phase industrial material can be slag, fly ash, silica fume, andor lime kiln dust. Depth sensing pixel pairs may be formed from depth sensing pixels that have different asymmetrical angular responses.
