A moving crank mechanism that is particularly adapted for use in a conveyor system. A moving crank remains in a substantially parallel position with respect to a fixed reference plane as the crank member is driven by its offset opposed ends along an endless loop. The closed loop vertical lift unit is adapted for use in an automated high-speed storage system. The vertical lift unit is adapted to be used as a primary storage location or as a lift for carrying objects in transit between levels in a storage system. The vertical lift unit includes a plurality of crank members with generally rigidly mounted shelves that are adapted to carry objects continuously and indefinitely as the shelves travel through a vertically oriented closed path. While traveling along the vertically oriented closed path the shelves remain parallel to a fixed horizontal plane so objects can be carried on the shelves while the shelves transition between the up and down reaches of the vertical lift mechanism. The opposed ends of the crank member are journaled in carriage members that are mounted to carry the respective ends of the crank member around the closed loop. The respective ends are carried around the closed loop at about the same rate. The closed loops are offset from one another by the amount of the crank offset. Shelf stabilizing mechanisms can also be employed.

The present invention is to provide a wireless LAN system which achieves a relatively effective use of communication band, while suppressing occurrence of hidden terminal problems.

When wireless terminal A and wireless terminal B respectively transmit signals (T123, T133), and Access Point (AP) in the wireless LAN system recognizes occurrence of contention, if AP successfully recognizes an address of sending source of this signal and a duration of this signal as a result of analyzing any signal from the wireless terminal A, AP transmits a CTS signal which gives a clearance for transmission to the wireless terminal A which is the source of sending the signal (T113). The wireless terminal A which is given the clearance for transmission by the CTS signal, resends a signal identical to the one previously sent (T127), whereas the wireless terminal B which is not given the clearance for transmission by the CTS signal withholds a signal transmission during the duration indicated by the CTS signal.
