Abstract: An information processing apparatus is provided which includes a processor for carrying out a pipeline processing over an instruction, a memory provided in the processor and input/output control means for giving access to the memory with a high priority, a memory access arranging method includes a step of causing a clock to be supplied to the processor to wait when a contention of access of the processor and the input/output control means to the memory is generated, a step of executing the access of the input/output control means to the memory, and a step of canceling the clock wait of the processor after ending the access of the input/output control means to the memory, and executing the access of the processor to the memory.

Abstract: A transfer mechanism distributes drive power from a drive power source of a motor vehicle to left and right front wheels and left and right rear wheels of the vehicle. A rear differential mechanism transfers the drive power to the left and right rear wheels. A clutch is provided between the rear differential mechanism and each of the left and right rear wheels. A control device independently controls an engaged state of each of the clutches. A speed-increasing mechanism sets revolution speeds of an output shaft of the transfer mechanism and of an input shaft of the rear differential mechanism to be the same and sets a speed of the outer circumference of the rear wheel to which the drive power is transferred, via an engaged clutch, to be faster than a speed of the outer circumference of the left and right front wheels.

Abstract: The power consumption and area of a programmable logic device formed from programmable logical elements can be reduced. In a programmable logic device 101 formed from programmable logical elements, there are provided first logical elements 102 and second logical elements 104 having the same logic as the first logical elements 102 but having an upper limit of operating speed designed to be lower than that of the first logical elements 102.

Abstract: It is an object to implement a small-scale data input/output mechanism to a memory at a high speed with a priority all the time for a memory provided in a processor.

Abstract: A vibration damping equipment for a torsional damper comprises a hub plate, side plates, a torsion spring, a friction block, and low rigidity members. Each low rigidity member is interposed between the hub plate and each friction block to be adjacent to each other through a partition of the hub plate. The low rigidity members are connected to each other on at least one axial side of the partition.

Abstract: A torsional damper comprises damper elements which are resiliently coupled by a spring arrangement and a friction generating device. One of the damper elements has a radially extending wall. The friction generating device includes a plurality of friction blocks received by the other damper element with play in the circumferential direction, and a spring arranged to bias the plurality of friction blocks against the radially extending wall. In order to absorb the shock of engagement of each of the plurality of friction blocks with the other damper element, a cushion is provided.
