摘要:
A method and apparatus for processing exceptions in a microprocessor having a plurality of pipelined stages. The method comprises the steps of generating an exception processing code at a given stage to indicate the occurrence of an exception at the given stage; temporarily stopping processing at the given stage; transferring the exception processing code to a special stage; decoding said exception processing code at the special stage; and causing the pipeline to execute exception processing when the exception processing code is decoded at the special stage. Using the invention, the microprocessor can avoid much of the delay and complexity resulting from using an external circuit to control exception processing and can cope with the occurrence of an exception at any stage without prematurely cancelling or reexecuting processing steps. The invention is simplified in both hardware and software, and can easily cope with expansion of the number of stages.

In a control valve abnormality detection method of detecting abnormality in a control valve, a characteristic expression representing the relationship between three factors in the normal state of the control valve is pre-set. The three factors consist of the displacement of the valve stem, a driving force from the valve stem driving device which changes upon displacement of the valve stem, and the force of the fluid which acts on one end of the valve stem through the valve. The three factors are detected on the basis of measurement result. On the basis of two factors selected from the detected three factors, the estimated value of one factor, which is not selected, is calculated by using the pre-set characteristic expression. The detected value of one factor, which is not selected, is compared with the calculated estimated value, and abnormality in the control valve is determined on the basis of the comparison result. A control valve abnormality detection apparatus is also disclosed.

In a stick-slip detection method, the displacement of a movable member having a slidable contact portion is detected. A first quantity of state is calculated on the basis of the detected displacement of the movable member. A second quantity of state, which can be estimated from the first quantity of state, is calculated on the basis of the detected displacement of the movable member. An estimated quantity of state is calculated by estimating a second quantity of state from the calculated first quantity of state by using the relationship between the first and second predetermined quantities of state which are obtained from the displacement of the movable member in a normal sliding state. The calculated second quantity of state is compared with the estimated quantity of state to determine an abnormal sliding operation of the movable member on the basis of the comparison result. A stick-slip detection apparatus is also disclosed.

A cast-iron product has a composition of 4.3-4.9 wt. % Carbon Equivalent (CE), 0.25-0.5 wt. % Chromium (Cr), 0.05-0.12 wt. % Tin (Sn), 0.4-1.2 wt. % Manganese (Mn), 0-0.1 wt. % Phosphorus (P), and 0-0.15 wt. % Sulfur (S), with the balance being Iron (Fe). A brake assembly comprises a sliding element made of such a cast iron, and the sliding element is adapted to slideably contact with a friction element or elements made of non-asbestos material and constitute the assembly. Further, a method of producing a cast iron product comprises the steps of casting a cast iron having a composition of 4.3-4.9 wt. % Carbon Equivalent (CE), 0.25-0.5 wt. % Chromium (Cr), 0.05-0.12 wt. % Tin (Sn), 0.4-1.2 wt. % Manganese (Mn), 0-0.1 wt. % Phosphorus (P), and 0-0.15 wt. % Sulfur (S), with the balance being Iron (Fe), releasing a mold at a temperature not less than A.sub.1 allotropic transformation temperature, and cooling the cast iron at a relatively high cooling rate.
