    • There are provided a method for machining a slide core hole and a measurement/correction system for use in machining of a slide core hole, which enable efficient machining of a slide core hole while utilizing the high-speed cutting performance of a five-axis machine tool. The method for machining an inclined slide core hole, comprised of a core pocket and a rod hole, in a mold as a workpiece by means of a five-axis machine tool having, in addition to X-axis, Y-axis and Z-axis, an A-axis for pivoting of a spindle head and a C-axis for rotation of a table, includes the steps of: pivoting the spindle head to meet the inclination angle of the slide core hole to be machined in the mold, and fixing the A-axis angle; spot-facing a shallow flat-bottomed spot-faced hole in the surface of the mold by using an end mill as a tool; drilling a guide hole in the bottom surface of the spot-faced hole by using a drill or a reamer as a tool; drilling said rod hole by using a gun drill as a tool with the guide hole as a guide for the gun drill; carrying out, as pre-machining before machining of said core pocket, shaping machining to form an intermediate pocket hole while expanding the spot-faced hole by using an end mill as a tool; correcting a reference point for use as a reference in machining of the core pocket based on measurement of the shape of the intermediate pocket; and executing a corrected machining program with the corrected reference point to carry out precision shaping machining of the core pocket while expanding the intermediate pocket by using an end mill as a tool.

    • A detector for an air/fuel ratio sensor, which is comprised of a structure formed by stacking an oxygen reference electrode, a dense zirconia solid electrolyte, a negative electrode, a porous zirconia solid electrolyte, a positive electrode and a porous protection film on one another, is formed over a ceramic substrate having a heater built therein. Thus, a combined air/fuel ratio sensor can be obtained which is operated in a short time (about 5 seconds or less) after power-on so as to comply with emission control applied immediately after startup and provides low power consumption and a high degree of reliability.
