This invention concerns quinazoline analogs of Formula I:where an A group is bonded to at least one of the carbons at the 5, 6, 7 or 8 position of the bicyclic ring, and the ring is substituted by up to three independent R3 groups. The differential amplifier provides a control voltage to the output circuit responsive to a difference between the reference and comparison voltages. With such a structure, by forming the extended shaft of a material having relatively high strength, the diameter of the extended shaft can be made smaller than that of the crankshaft, and hence, the diameter of the sprocket provided on the extended shaft can be reduced. The first and second stiffeners are coaxially wound exterior to the proximal inner liner. Non-time-sensitive data associated with recorded programs may be stored in a way that allows the user to interact with the data on playback as if the program were being originally aired. The valve body and the sub-valve body ascend together by pressing the fluid-storing portion ; and the valve body travels to an open position and the sub-valve body travels to a detached position.
