    • For detecting the end point of polishing by a CMP method, a transparent window member (11) having a positive refractive index distribution is provided in a light transmission area of a polishing pad. The window member (11) has areas (11a) having a high refractive index and areas (11b) having a low refractive index in its window face. In a cross section, perpendicular to the window face the high-refractive index areas (11a) and the low-refractive index areas (11b) are alternated in stripes. They are in a Fresnel zone plate arrangement where the first area (center circle) is a bright one (area having a high refractive index) in the window face. The Fresnel zone plates (F) are arrayed in a matrix in the window face of the window member (11).

    • A multiwheel grinding machine for grinding the journal regions of a crankshaft (63) which is mounted between a headstock and a tailstock, comprises a single radially adjustable workrest (60) engageable with a central journal region, left-hand and right-hand size gauges (64 and 66), and a surveyance gauge (62) for gauging the diameter of the central journal region adjacent the workrest. The position of the workrest may be adjustable under computer control to compensate for any grinding errors in the central journal region. Any difference hbetween the readings from the two size gauges (64 and 66) may be corrected by pivoting the common shat, upon which the multiple grinding wheels are mounted, by an appropriate amount.

    • A head for the linear dimension checking of mechanical pieces including a casing, an arm carrying a feeler for touching a surface of the mechanical piece to be checked, a fulcrum, coupled to the casing and the arm, for enabling displacements of the arm with respect to the casing and a transducer for providing signals depending on the position of the arm with respect to the casing. The head has specific flexibility and modularity features, thanks to the possibility of operating from the exterior for adjusting and replacing various components. The transducer is of the inductive, half-bridge type, with multiple windings. An integral element for the electric connection to a processing unit includes the windings of the transducer, a cable and a connector, and the latter comprises a rapid locking/unlocking device. The ends of the cable are connected between the windings of the transducer and the connector by means of an over-moulding process of a plastic material.
