To provide an end point detection method applying a resonance phenomenon, an end point detection apparatus, and a chemical mechanical polishing apparatus on which the detection apparatus is loaded for monitoring variation in the thickness of an electrically conductive film in real time, reliably detecting a polishing end point of the electrically conductive film at high accuracy, without generating noise, low power consumption, and capable of reducing the cost.In order to achieve above described objects, the present invention provides an end point detection method applying a resonance phenomenon in which a polishing end point is detected when the electrically conductive film is polished and removed to an appropriate thickness, wherein a sensor 37 composed of an oscillation circuit of the Colpitts type or the like having a planar inductor and a concentrated constant capacitor is used, and the variation in the thickness of the electrically conductive film is monitored in real time from the variation in the oscillation frequency of the sensor 37 caused along with the variation in the thickness of the electrically conductive film opposed to the planar inductor.

Conventional transcoding techniques cannot generate a continuous encoded stream when the transcode operation is interrupted due to insufficient power, etc. and later resumed, causing a degradation in the quality of the image or sound at the point of interruption. A transcoding technique of the present invention determines whether a transcode operation is to be interrupted due to power failure, etc. and if so, stores coding information required to resume the transcode operation at the point of interruption.
摘要:
A method for bending a metallic flanged member includes the steps of applying a compressive force to a flange 2 of a metallic flanged member 1 in a direction that intersects a longitudinal direction of the metallic member for compression plastic deformation of the flange, and thereafter bending the metallic flanged member 1 along a flanged side thereof in such a manner that the flanged side of the metallic flanged member is situated on an inner side of a bending process, and an apparatus for use with the same method.
