Abstract: A method is provided that includes a main laminate making step of forming a plurality of main magnetic poles onto a substrate, covering each magnetic pole with a first protective film, and forming onto the first protective film a stopper film provided with openings at respective parts opposing the main magnetic poles. Each opening is wider than a planar width of a corresponding main magnetic pole, so as to make a main laminate. The method includes a main polishing step of polishing the first protective film and main magnetic poles through the openings of the stopper film in the main laminate by a CMP method. In the main laminate making step, the openings in the stopper film is provided with a width distribution.
Abstract: Block representative values are set adaptively based on the feature amount concerning the distribution state of a prepared histogram of input image data. Thus, if block truncation coding is executed based on an input image having mixed CG image and scanned image areas, efficient coding can be performed and a high-quality decomposed image can be provided. Further, when the histogram is divided into image data groups, the image data groups can be again divided to provide a high-quality decomposed image, thus efficient coding can be performed and a high-quality decomposed image can be provided more reliably.
Abstract: A mail transmission/reception system, in which a user on the transmitting end, who wishes to revise or delete a print mail mistakenly sent to a remote user, can transmit a cancel mail to the destination address of the same remote user to have the specified print mail deleted on the remote user's computer system in S690, thereby preventing the print mail from being printed on the remote user's end. Also, the user on the transmitting end can know whether the printing has been prevented based on mail returned from the remote user in S660-S680 and can take appropriate measures when the mail cancellation has not been successful.
Abstract: A light beam from a light source is formed into an annular beam and an inner wall of a hole in an object is illuminated with the annular beam.
