摘要： A defect detection optical system includes a light receiving system including n light receiving elements arranged in a direction perpendicular to a main scan direction, for focusing an image thereon such that the image becomes in the arranging direction of the light receiving elements, in which, when a width of the image focused thereon in the main scan direction is equal to or smaller than the width of the light receiving elements, light reflected from a recessed or protruded defect is swung in the width direction of the light receiving elements and a light receiving area of the light receiving elements is reduced. When the reflection light from the recessed or protruded defect is; swung in sloped portions of the defect, an amount of light received by the light receiving elements is at least reduced, so that two detection signals having levels lower than those when there is no defect are obtained.

摘要： A mobile phone 1 receives a home cell signal sent from a base station B1 and a foreign cell signal sent from a base station B2 or from a mobile phone 21 in a foreign cell A2. The mobile phone 1 receives spreading codes C2–C4 sent from the base station B1, as home cell codes. The mobile phone 1 detects the interference between the home cell signal and the foreign cell signal. When the interference is detected, the mobile phone 1 receives a spreading code C1 sent from the base station B2 or from the mobile phone 21, as a foreign cell code. The mobile phone 1 cancels an interference signal by joint detection, using the home cell codes and the foreign cell code.
