Systems and methods for monitoring crankcase ventilation system integrity are disclosed. The optics consists of CaF2 as the major component and Mg in an amount in the range of 13 ppm to 20 ppm while Ce and Mn are <0. In one embodiment the chamber is formed of two adjacent, parallel heat exchange plates, wherein at least one plate has a peripheral lip which, in contact with the opposing plate, forms the closed chamber. The second member is moveable from a first position connected to a lateral side of the first member and to a second position where the moveable second member is not connected to the lateral side. The invention further relates to a method for treating a fabric article in need of treatment that combines a clothes dryer and liquid dispensing system designed to uniformly treat fabric. A method includes manufacturing the resin sealing-type semiconductor device.
