There is provided a new medium structure to record a bar code for copyright protection or the like in an optical information recording medium capable of recording and reproducing information by a laser with respect to a dye. When a laser beamis irradiated and an optical discis rotation in the direction of an arrow F, the dye of a recording layer is decomposed, a mark piece MA of a bar codeis formed, and a substrate is deformed by heat generated by the dye decomposition. Next, the position of the laser beamis shifted to a position where a part overlaps with the mark piece MA, and when the optical disc is similarly rotated in the direction of the arrow F, a mark piece MB is formed to overlap with the mark piece MA. The above processing is repeated, so that the length of a bar is sequentially lengthened, and the bar code with a length along the standard is formed.

An optical property measurement apparatus is equipped with an optical system unit that selectively places an opening section for passing illumination light, a microlens array for measuring wavefront aberration, and a polarization detection system for measuring a polarization state of the illumination light on an optical path of the illumination light. Accordingly an illumination shape and a size of an illumination optical system, wavefront aberration of a projection optical system and a polarization state of the illumination light can be measured together. Therefore, for example, even when exposure is performed with polarized illumination that is a type of modified illumination, highly-accurate exposure can be achieved by adjusting various optical systems based on the measurement results.

A signal-level converter is provided between a first terminal and a second terminal. The first terminal is connected to a first logic circuit operating at a first supply voltage higher than a given reference voltage. The second terminal is connected to a second logic circuit operating at a second supply voltage higher than the first supply voltage. The signal-level converter has a switching transistor that forms a current passage between the first and the second terminals in response to a control signal supplied to a gate of the switching transistor and a bus-hold circuitry, provided between the switching transistor and either the first or the second terminal as the output terminal, the other being the input terminal, and configured to convert a voltage level of a signal transferred via the switching transistor into another voltage level at the output terminal. The bus-hold circuitry may have two bus-hold circuits between the input and the output terminals, for two-way signal transfer. The bus-hold circuitry may have one bus-hold circuit between the switching transistor and the output terminal, for one-way signal transfer. These circuit arrangements offer reduced chip size and simplified control operations for accurate output-terminal voltages. Moreover, the arrangements omit one direction-switching terminal in two-way signal transfer.

An image of a design pattern of wallpaper stored in a data base (DB) is viewed by a user computer of a user who is a general consumer or a contractor from a server computer provided in a head office of a wallpaper manufacturer through the Internet. Further, upon accepting an order of wallpaper from the user who saw the image by the user computer, the server computer fetches the image of the design pattern from the DB. A wallpaper printer then prints the image on a wallpaper sheet, thereby manufacturing the wallpaper desired by the user. The produced wallpaper is delivered to the user who gave out the order by, for example, a door-to-door delivery service.

Correlation values between a plurality of templates prepared beforehand and a picture-element data distribution as a pick-up result of an image are calculated, and the position of a maximum template whose correlation value is the maximum of the calculated correlation values is obtained. Subsequently, a curved surface function is calculated which fits the distribution of calculated correlation-values in positions near the maximum template's position, and the position of the picked-up image is calculated based on the curved surface function. As a result, the number of templates prepared beforehand to achieve desired accuracy in detecting a position and the number of times of calculating correlation-values can be reduced, and the image position can be quickly and accurately detected.
