A bit apparatus in which a cutter member having cutting teeth is axially supported on a shaft for rotation about the shaft, and a bearing mechanism is interposed between the cutter member and the shaft. In a semiconductor area of the semiconductor chip, every contact pad of the plurality of contact pads has an associated pad cell provided, which includes at least one of a driver or a receiver and is configured to drive output signals or receive input signals on its associated contact pad, if the driver or receiver is connected to the contact pad. Monitoring, and processing means to interpret the results are comprised in an external coagulometer device. The other gear wheel is engaged with a shutter speed adjustment gear formed in a periphery of the shutter drive lever. The invention further provides nucleic acid primers and probes for use in methods for detecting the presence or absence of disease-causing genetic deletion at the SHOX locus of a horse. The parallel computer system performs a simultaneous search on each node of the computer system using the unique key and then utilizes a global combining network to combine the results from the searches of each node to efficiently and quickly search the entire database.
