    摘要: A pair of edges that are located at ends as viewed in the widthwise direction of a design pattern are recognized. On the basis of the edge direction in which the paired edges are recognized, edge points on the design pattern are detected as sub-pixels. The widthwise dimension of the design pattern is calculated on the basis of the edge points. In addition, the widthwise dimension of a circuit pattern is calculated at the same position as the widthwise dimension of the design pattern. On the basis of the calculated widthwise dimensions, the semiconductor wafer circuit pattern is checked.

    摘要: A door device for a vehicle includes a cable for connecting a handle device and a lock unit. A cable holding member mounted to the handle device is displaced between an engagement position in which the cable holding member engages with the cable and a non-engagement position in which the cable holding member does not engage with the cable. A contact portion of a door panel is configured such that when the handle device is being mounted to the door panel, the contact portion contacts the cable holding member in the non-engagement position and interferes with the assembly of the handle device to the door panel and the contact portion does not contact the cable holding member in the engagement position.

    摘要: A photolithography mask inspection apparatus has at least two sensors. One sensor is configured to sense light transmitted through an object to be inspected, and the other sensor senses light reflected off the object. A first optical system is arranged to expose a first portion of the object with a first light beam, and a second optical system is arranged to expose a second portion of the object, spaced form the first portion, with a second light beam. A third optical system focuses the transmitted light on to the first sensor, as well as the reflected light on to the second sensor. A defect detecting circuit is also provided to detect a defect of the object, based upon image data associated with the reflected and transmitted light.
