Abstract: This application describes a manufactured component and method for forming the component. The component comprises: a plurality of parts (212, 214) joined together by a straight line joint (216) and a multi-faceted joint (218). The plurality of parts define a cavity (236) having an internal surface (226) and an external (222) surface. The straight line joint extends through a wall of the component along a straight line between the external surface the internal surface; and, the multi-faceted joint includes an external joint line extending from an external surface to meet an internal joint line which extends from an internal surface, the external and internal joint lines being at an angle to one another. The internal joint line and the straight line joint are aligned with one another such that a straight line extending from the straight line joint will coincide with the internal joint.

Abstract: A method and system for removing substances from a surface, in which the surface is irradiated by high-energy laser radiation, characterized in that the laser parameters are chosen to selectively remove one or more predetermined substances from the surface without removing other substances from the surface.

Abstract: A method of repairing a component comprising: removing a damaged portion of the component to expose a region of the component; providing a patch having a rim exceeding the dimensions of the exposed region; placing the patch on the exposed region of the component such that the exposed region is covered by the patch and the rim is spaced apart from the exposed region; joining the patch to the component around the rim of the patch; and diffusion bonding the patch and the component together. The rim may be spaced apart from the exposed region such that the step of joining the patch to the component does not affect the exposed region. The method may further comprise machining a recess in the damaged region of the component.

Abstract: When capacity coupling between an output gate electrode (OG) and a last-stage transfer electrode is large at an output end of a CCD shift register, an electric potential of the OG is varied according to transfer clocks with the result that noise is liable to generate in an output signal. As measures for this, convex portions projecting horizontally are formed in those positions of the last-stage transfer electrode and the OG, which correspond to a channel region, and overlap between the electrodes is caused only on the convex portions. A clearance is formed between the OG and the transfer electrode except those locations, in which the convex portions are provided. In that location, in which the OG and the transfer electrode, respectively, are extended relatively lengthily toward wirings, the electrodes do not overlap each other. In this manner, capacity coupling between the electrodes is reduced.
