Heterocyclic compounds, and pharmaceutical compositions thereof, are disclosed as ROR\u03b3t modulators that have a formula represented by the following:and wherein n1, n2, R1, R2, R3, and R4 are as described herein. In one aspect, slots are formed in posts and receive opposed ends of the circuit board. The modules further comprise flex circuits with one or more microprocessors to electrically engage the ink cartridges and a postage evidencing system. An actual value of the rotational angle coincides with a value, which is shifted from the reference angle in a valve closing or opening direction by a changing range decided by changing factors of a sensor side andor a mechanical-part side.
