Abstract: A rod and rod cup alignment apparatus for a drilling machine has a receptacle for receiving a drill rod of the type having at least one rod flat, where the drill rod has a leading corner and a trailing corner relative to the direction of its rotation. The receptacle has at least one cup flat disposed on the inner surface of the receptacle and the cup flat further has a first top surface and a second top surface. The second top surface has a slope downward toward the bottom of the rod cup, so that, as the drill rod is lowered into the rod cup while the drill rod is rotating, the leading corner of the drill rod is caused to move downward along the second top surface, whereupon the trailing corner of the drill rod contacts the first top surface, thereby aligning the drill rod flat with the rod cup flat.

Abstract: The drilling machine of the present invention includes a frame, a tower, a rotary head, and a rotary head guide. The tower is mounted on the frame and includes an elongated member. The rotary head is engageable with the drill string and slidably coupled to the elongated member for movement along the tower. The rotary head guide includes a support, a wear block, a backing bar, and an adjustment mechanism. The support is coupled to the rotary head, the wear block is slidably engaged with the elongated member, and the backing bar is coupled between the wear block and the support. The adjustment mechanism is coupled to the support and engages the backing bar such that adjustment of the adjustment mechanism moves the backing bar away from the support to move the wear block against the elongated member.

Abstract: The drilling machine includes a frame that is supported for movement over the ground and a tower that is mounted on the frame. A rotary head is movable along the tower and engageable with a drill string for rotating the drill string. A pull down cable is connected to the rotary head for pulling the rotary head downward for pushing the drill string into the ground. A pull back cable is connected to the rotary head for pulling the rotary head upward for pulling the drill string out of the ground. The pull back cable is subject to a slack condition in response to elastic stretch of the pull down cable. A slack take-up device is connected to the pull back cable to remove the slack created in the pull back cable by the elastic stretch of the pull down cable.

Abstract: A dual access debugging architecture. This architecture allows the microprocessor to select between external debugging, supported via the physical system interface, and internal debugging, supported via logic within the microprocessor which is controlled by decoded software instructions. In one example of the present invention, a microprocessor includes a system bus interface and a program decoder which is coupled to the system bus interface. The system bus interface is coupled to a system bus to which external memory is coupled. Debugging operations are stored as debugging instructions in the external memory. When these debugging instructions are retrieved from memory, through the system bus and the system bus interface, they are decoded in the program decoder of the microprocessor and they in turn cause the microprocessor to enter a first debugging mode which is controlled by the debugging instructions. The first debugging mode may be referred to as an internal programmable method.

Abstract: One embodiment of the present invention provides a state machine that receives as input a clock signal and determines a frequency relationship between circuits. The state machine generates outputs that control buffer circuits. The buffer circuits latch signals input to them until the output signals from the state machine cause the buffer circuits to latch new input signals. The buffer circuits are used to latch data until that data can be used appropriately.

Abstract: A method and an apparatus using, in one embodiment, a multiple split mode for issuing multiple read or write requests that may be used during a data transaction within a computer system. In one embodiment, a processing unit comprises a bus arbitrator having bus control lines for controlling a bus, which transmits address and data information. The arbitrator is capable of issuing multiple consecutive read or write requests including at least one read request on the bus without releasing control by the processing unit over the bus during the consecutive read or write requests. In addition, the arbitrator is also designed to abort consecutive read requests during address cycles in response to bus control lines.
