A video camera includes an LCD monitor. Embodiments of the valve comprise a flexible membrane with one or more linear slits therethrough, and means for applying tension to the flexible membrane in-line with the linear slits. Of course, many alternatives, variations, and modifications are possible without departing from this embodiment. The valve guide also includes a recess portion, situated in relation to a water jacket and between the contact portions. The resulting polymers have a narrow polydispersity and are useful for manufacturing photoresists. The mask layer is disposed on the dielectric layer and covers the insulation layer and the mask layer includes an opening to expose the connection region of the pad.
