Abstract: PURPOSE: A method for loading stand-by processor in a dual processor is provided to reduce load between the loading-use processor and a processor, and reduce the system initialization time by having an active processor load program and data. CONSTITUTION: A variable required for loading is initialized after active/stand-by negotiation is performed. After the variable is initialized, it is determined if the active side is normal. If so, the duplex mode is set up as active mode and a loading request is transmitted to an SSL. Program and data are loaded through IPC, and if the loading is ended, a CROS is run. If there is a failure in the active side, the duplex mode is set up as stand-by mode and an SBYSTS signal is sent to the SSL in order to recognize the stand-by state. If the acknowledge message is received from the SSL, the message is analyzed to decide either stand-by loading or dual copy. If it is determined to be dual copy, the dual copy is done through an active side. If the dual copy is ended, the CROS is run.

Abstract: PURPOSE: A cooling structure of a piston is provided to prevent supercooling of a piston in low-speed operation and to facilitate the cooling of a piston in high-speed operation by controlling the amount of draining oil. CONSTITUTION: A valve(9) is received in a valve mounting hole(8) formed in a piston(1) body. A spindle(10) is received in a wax pellet(11), and a wax body(12) is sealed in the wax pellet. The wax body expands or contracts according to the temperature of the piston. Upon expansion of the wax body, the spindle is pushed out. Upon the contraction of the wax body, a return spring(13) rebounds to return the spindle to its original state. In low-speed operation, the wax body is contracted and the valve is received in the valve mounting hole. Then, sectional area of an oil drain hole(7) is maximized and amount of oil drained from an oil gallery(3) is increased. Thus, oil filling efficiency of the oil gallery falls and supercooling of the piston is prevented. In high-speed operation, the wax body expands and the valve is exposed to the oil drain hole. Then, sectional area of the oil drain hole is reduced and amount of draining oil is reduced. Thus, the oil filling efficiency of the oil gallery is enhanced and cooling efficiency of the piston is improved.
