Abstract: A phase adjustment circuit includes a comparator circuit and a synchronization circuit. The comparator circuit compares, with respect to each of multiple lanes, a common reference clock signal fed to each lane with first and second transmission clock signals each of which is in antiphase and is generated in each lane. The synchronization circuit synchronizes, with respect to each lane, data distributed to each lane with one of the first and second transmission clock signals, wherein a phase difference between the one of the first and second transmission clock signals and the reference clock signal is smaller than a phase difference between the other of the first and second transmission clock signals and the reference clock signal.

Abstract: A cleaning tool is for removing foreign matter from a surface of a photographic device. The cleaning tool includes an adhesive member and a body. The adhesive member has an adhesive surface for the foreign matter to adhere to. The body has a first end to which the adhesive member is attached, and has an end surface located at a second end being opposite to the first end. The outline of the adhesive surface includes a linear section, and the shape and orientation of the adhesive surface are represented on the end surface.

Abstract: A cleaning tool is to remove foreign matter from a surface of a photographic device. The cleaning tool includes an adhesive member and a stick body. The adhesive member has an adhesive surface for the foreign matter to adhere to. The stick body has an end to which the adhesive member is attached. The adhesive surface has an arcuate area, of which part of the outline is an arcuate section and a rectangular area that has a rectangular shape. The arcuate area is located between two theoretical lines which extend from two adjoining sides of the rectangular area.
