An operation arrangement work is accelerated by improving efficiency of not only process of generating an operation arrangement proposal but also process of confirming whether the operation arrangement proposal is good or not by a user. A plurality of pockets are formed within the support base. The connecting mechanism moves in a first direction when the sliding means moves forward, and the connecting mechanism moves in a second direction when the sliding means moves backward. Embodiments of the present invention can advantageously provide a cost effective approach for enhancing VCO frequency ranges from a singly VCO, suitable for phase-locked loop applications. A primary array etching process may be performed with respect to the nitride film using a first photoresist pattern for opening a main pixel region in the pixel region. The frame can, for example, be a kink feedback frame associated only with a particular transmitter and receiver.
