An angle ?1 of the shoulder lateral groove 10 with respect to the tire axial direction is larger by 10 to 40 degrees than an angle ?2 of the first shoulder lug groove 11 with respect to the tire axial direction.

Abstract: An information processing apparatus includes: a power-failure detector that detects a halt of power supply from a power source; a standby power supply that supplies, when the power supply from the power source is halted, standby power to a processor, a memory, and a storing device; and a disconnector that disconnects communication between the processor and a peripheral device. When the power-failure detector detects the halt of power supply from the power source, the disconnector disconnects the communication between the processor and the peripheral device and the processor carries out a memory backup process that reads data from the memory and stores the read data into the storing device. With this configuration, the memory backup process is surely carried out even in the event of power failure.

Abstract: PCI devices write an MSI message in a memory and polling routines, which are executed by CPU cores respectively, poll the memory. The polling routines poll a cause of interrupt during an interval between tasks, during an interval between threads, and during idle and cause a CPU core with the lowest load to perform interrupt processing. An IO task performs inter-task communication with another IO task by using a command queue.

Abstract: A tire having a rotation timing indication hole of the invention has a rotation timing indication hole comprising a multi-step hole provided in a tire tread, and respective steps of the hole have different contours from each other. Since the contour of the hole changes when the tire is worn, the rotation timing of the tire can be recognized.

Abstract: A multi-core processor system has a processing order manager which manages command blocks in a lock acquired state under exclusive control, an assigner which assigns a command block managed by the processing order manager to one of the processor cores, an exclusion manager which manages command blocks in a lock acquisition waiting state under the exclusive control, and a transfer controller which, when the command block in the lock acquisition waiting state managed by the exclusion manager gets into the lock acquired state, releases the command block from the exclusion manager, and registers the command block in the processing order manager, thereby efficiently processing tasks.
