The wire rod is made of steel containing C: 0.6 to 1.1%, Si: 0.1 to 2.0%, Mn: 0.1 to 1%, P: not more than 0.20%, S: not more than 0.20%, N: not more than 0.006%, Al: not more than 0.03%, and O: not more than 0.003%, the balance including Fe, and unavoidable impurities. Further, the wire rod comprises a pearlite structure wherein an area ratio of a second-phase ferrite is not more than 11.0%, and a pearlite lamellar spacing is not less than 120 mum.

The sensor malfunction detection system for a gas-turbine engine is configured to determine or check once every first predetermined time period whether the outputted value from the sensor is within a permissible range and determines that the sensor is faulty when the result of the check is at least one result between the case of the number of times the outputted value is found not to be within the permissible range exceeding a first predetermined value and the case of the number of times the outputted value is consecutively found not to be within the permissible range exceeding a second predetermined value. Since the system discriminates whether the total number of times the sensor output is found to be outside the permissible range is fewer than the first predetermined value, it can avoid erroneous detection of transient abnormalities caused by noise or the like as sensor malfunction, and since it discriminates whether the number of times the sensor output is consecutively found not to be within the permissible range is fewer than the second predetermined value, it can promptly detect sensor malfunction owing to wire breakage or the like. The system can therefore detect sensor malfunction with good accuracy using a simple configuration.

There is provided a layout structure of a semiconductor integrated circuit capable of preventing the thinning of a metal wiring line close to a cell boundary and wire breakage therein without involving increases in the amount of data for OPC correction and OPC process time. In a region interposed between a power supply line and a ground line each placed to extend in a first direction, first and second cells each having a transistor and an intra-cell line each for implementing a circuit function are placed to be adjacent to each other in the first direction. In a boundary portion between the first and second cells, a metal wiring line extending in a second direction orthogonal to the first direction is placed so as not to short-circuit the power supply line and the ground line.

The invention discloses a process for producing an ultra-fine copper wire. The process comprises the following steps of: 1) dragging a oxygen-free copper rod: preheating and drying electrolytic copper, smelting the electrolytic copper into a smelting device, covering the surface of a copper solution with charcoal and graphite scale, performing on-line degassing and deoxidization, dragging a copper rod in a clutch type vacuum environment by a dragging machine set, and sending the copper rod into a take-up device; 2) performing continuous extrusion, namely continuously extruding the oxygen-free copper rod to form a copper wire, and cooling and drying the copper wire through a vacuum anti-oxidization pipe and a water tank; and 3) drawing, namely drawing the copper wire for many times, wherein emulsion is used for lubricating and cooling the copper wire during the drawing process, and the copper wire is drawn greatly first till the diameter is 1mm to 3mm and then drawn till the diameter is 0.1mm to 0.5mm, resistance internal heat type continuous annealing is adopted, and finally the copper wire is drawn finely until the diameter of the copper wire is 0.01 to 0.05mm to obtain the ultra-fine copper wire. The process has the characteristics of short flow, high production efficiency, low wire breakage rate and the like.
