Abstract: A memory system includes a non-volatile memory and a controller that includes a first memory and is configured to write log data to the first memory, including a history of commands for controlling the memory system. An information processing system includes the memory system and an information processing device configured to store an expected value and to transmit a signal that instructs the memory system to stop when a value of the log data transmitted from the memory system does not match the expected value. The expected value and the transmitted value are determined based on the log data of the memory system.

Abstract: A crane includes a lower traveling body, an upper turning body that is turnably provided on the lower traveling body, a counterweight that is mounted on the upper turning body, and a ladder for getting on and off the upper turning body. The ladder has an engagement member that is able to be engaged with and disengaged from an engaged portion provided at the upper turning body, a support portion that supports the engagement member, and a following mechanism that is interposed between the engagement member and the support portion. When the engaged portion in a state of being engaged with the engagement member is moved downward with work of mounting the counterweight, the following mechanism causes the engagement member to follow downward movement of the engaged portion.

Abstract: A working machine with a crawler includes a lower traveling body having a pair of crawlers, an upper turning body, an extension beam installed rotatably to be parallel in a longitudinal direction of the crawler, a fitting portion opened in a side frame of the crawler, a fixing pin fixing the extension beam to the side frame, a fixing pin insertion hole, a fixing pin fitting hole, and a reinforcement rib, in which the extension beam extends to be inserted into the fitting portion, and the reinforcement rib is provided at a center portion of an opening of the fitting portion, and the fixing pin fitting hole is disposed at a position which is deviated from an imaginary center line extending along a longitudinal direction of the fitting portion from the center portion and does not interfere with the reinforcement rib.

Abstract: An oil strainer which sucks an oil is disposed within an oil pan connected to a lower portion of a combustion engine. The oil strainer includes a strainer main body, which accommodates a filter element and extends so as to be inclined relative to a horizontal line, a suction port formed in a lower portion of the strainer main body, and a discharge port formed in an upper portion of the strainer main body.

Abstract: According to one embodiment, a memory system includes a memory unit, a first controller, and a second controller. In the memory unit, first to fourth levels (first level<second level<third level<fourth level) are written based on first and second data. The first controller comprises a first write mode of writing the fourth level based on the data of the second page and then writing the second and third levels and a second write mode of writing the third and fourth levels and then writing the second level. The second controller issues at least one of second and third commands to be supplied to the first controller in order to select at least one of the first and second write modes.
