A multi air conditioning system for adjusting the amount of refrigerant flowing into indoor units determined to be in a stopped state, to improve the overall system efficiency, and a method for operating the multi air conditioning system. The system also includes a support structure supported by the lift structure, and a table supported by the support structure. Next, an opening is formed in the semiconductor substrate in a region overlapping the predetermined region. Furthermore, a gyro filter uses data processing in floating-point format to calculate displacement data for a required amount the image-capturing device is to be displaced and a Hall filter uses data processing in floating-point format to generate drive data for the focus adjustment member. Each one of a plurality of storage nodes is coupled to a separate one of the plurality of alternating semiconductor regions. Torque transmission between the shaft and the reamer is accomplished by torque transmitting tabs or a threaded connection.
