摘要:
A virtual computer system executes a virtual computer control program on a physical computer and thereby causes guest programs on the logical partitions, respectively. The virtual computer control program includes an error recovery module to periodically recover from an error in a cache memory, an error interruption handler module responsive to an interruption notice caused by an error which has occurred in the cache memory, to recover from an error in the cache memory, and an error data initialization module to recover from an error in the cache memory with shutdown or restart of one of the logical partitions as a momentum. And the virtual computer control program conducts recovery processing from an error in the cache memory.
摘要:
A hydraulic power transmission device in a work vehicle transmits motive power from two hydraulic motors disposed in parallel to each other. The hydraulic power transmission device includes: a case; a first motor shaft and a second motor shaft respectively disposed in a right-side area and in a left-side area inside the case, each linked to one of the two hydraulic motors; a counter shaft disposed in an area ranging between the first motor shaft and the second motor shaft in the case; an output shaft; a first transmission mechanism that transmits motive power from the first motor shaft to the output shaft via the counter shaft; a second transmission mechanism that transmits motive power from the second motor shaft to the output shaft; and a hydraulic clutch device disposed at the counter shaft, that transmits the motive power from the first motor shaft to the output shaft or cuts off transmission of the motive power.
摘要:
A preventive and/or therapeutic agent for post-transplant arteriosclerosis occurring as a rejection response to organ transplantation or for auto- or allo-arteriovenous graft post-transplant intimal thickening, wherein the agent contains, as an active ingredient, a monocyte chemoattractant protein-1 (MCP-1) function inhibitor. Administration of the MCP-1 function inhibitor enables prevention and treatment of post-transplant arteriosclerosis occurring as a rejection response to organ transplantation or for auto- or allo-arteriovenous graft post-transplant intimal thickening.
