A filtration apparatus having a cover pivotably installed through a hinge mechanism has a casing bracket secured to a casing flange and a cover bracket secured to the cover. The substrates are high temperature insulating materials provided with a conductive pattern. The geographic area includes a plurality of geographic sub-areas that each correspond to a geographic sub-designator. The ball joints and the adjusting nut attachment are formed at their respective positions on an integrated metallic member so that they can be attached as an aiming unit to the low-beam lighting assembly attachment. The intermediate layer is formed of a material that is higher in Vickers hardness than the metal material used to form the metal portion, the metal material used to form the first metal layer and the metal material used to form the second metal layer. The technician enters a diagnosis code and a treatment code representing the diagnosis and treatment of the patient.
