Abstract: The invention provides a loader work machine with improved front visibility and improved aesthetic appearance. The loader work machine includes a self-propelled machine body, a work device having a boom, a boom cylinder, and a side frame for vertically pivotally supporting base portions of the boom and the boom cylinder, and a frame unit for attaching the work device to the self-propelled machine body. The frame unit has a support platform projecting laterally outward from the self-propelled machine body and a main frame mounted erect on the support platform for supporting and connecting a lower portion of the side frame. An accumulator is connected to the boom cylinder for absorbing shock occurring during a vertical pivotal movement of the work device and this accumulator is attached to the frame unit.

Abstract: A multipurpose terminal receives an address signal and a data signal. An address valid terminal receives an address valid signal indicating that a signal supplied to the multipurpose terminal is the address signal. An arbiter determines which of an external access request and an internal refresh request is given priority. The arbiter disables reception of the internal fresh request in response to a fact that both a chip enable signal and the address valid signal reach a valid level (an external access request). The arbiter enables the reception of the internal refresh request in response to completion of read or write operation. As a result, in a semiconductor memory device including the multipurpose terminal which receives the address signal and the data signal, contention between the read operation and the write operation, and a refresh operation which responds to the internal refresh request is prevented, which prevents a malfunction.
