  • Publication number: 20030128642
    Abstract: An optical disc is formed with a guiding groove from an inner periphery side toward an outer periphery side of the optical disc at constant groove width and constant groove intervals, and the optical disc can detect a predetermined frequency by forming a wobble on an end of the guiding groove. When the wobble is rotated at constant linear velocity, a plurality of constant frequencies are obtained with respect to a predetermined recording position of the guiding groove.

  • Patent number: 5179678
    Abstract: A cache controller is coupled to a cache memory coupled through a bus to a microprocessor, for controlling the cache memory in response to a signal from the microprocessor. The cache controller comprises an address signal terminal and a control signal terminal for receiving an address signal and a control signal from the microprocessor, and a clamp signal terminal for receiving a clamp signal from the microprocessor. The cache controller also includes an input circuit coupled to the address signal terminal, the control signal terminal and the clamp signal terminal for outputting the address signal and the control signal as they are when the clamp signal is inactive and for generating an output address signal and an ouput control signal having a predetermined logic level when the clamp signal is active.

  • Patent number: 3964562
    Abstract: Steering system for an endless track type tractor having an engine, a power distribution device for equally distributing the power of the engine to two outputs, a pair of power trains each including a torque converter, a transmission and a steering brake for transmitting the power to each of a pair of lateral shafts adapted to selectively drive an endless track through a sprocket for turning the tractor rightwardly or leftwardly. The transmissions and the steering brakes are hydraulically actuated through hydraulic cylinders and electromagnetic valves controlled by a manually operable steering switch mechanism so as to shift either one of the transmissions to neutral while the related one of the steering brakes is actuated to braking position for the turning of the tractor at a rate determined by the fluid pressure supplied to the hydraulic cylinders.
