Abstract: A camera casing of the present invention is an integral two-color molded product whose case main body (32) consists of a transparent rigid resin layer (32a) and an opaque rigid resin layer (32b). Essential parts of the camera are exposed through the transparent resin layer (32a), so the camera may be operated from outside the casing. The casing is collected and melted as a whole without discriminating between the transparent rigid resin and the opaque rigid resin, to be recycled as a material for the opaque resin layer (32b) when the case main body is newly formed by two-color injection molding.

Abstract: The present invention provides a method of operating a lithographic projection apparatus including calculating a change in aberration effect in the projection system, due to heating effects, as a function of time, based on at least one set of predetermined parameters; and adjusting the lithographic projection apparatus to compensate for the calculated change in aberration effect. The parameters are obtained by a calibration operation, which may comprise a coarse calibration followed by at least one fine calibration. The coarse calibration yields a first estimate of at least a subset of the parameters. The estimate can be used as an input for a subsequent fine calibration. The calibration may also comprise a single fine calibration.

Pattern exposure is conducted by using the first exposure section and the second exposure section on the basis of the detected positional relationship.

Abstract: The invention provides a projector capable of cooling a light-source lamp efficiently and suppressing noises as well. In a first cooling system, the base side of a light-source lamp, which reaches a high temperature, is intensively cooled by a first sirocco fan. An axial-flow exhaust fan is provided close to the light-source lamp so that cooling air is allowed to quickly flow while cooling the light-source lamp. Therefore, even when the first sirocco fan, in which the air pressure of cooling air is liable to be reduced, is used, heat generated in the light-source lamp can be smoothly radiated, thereby efficiently cooling the light-source lamp. Since the first sirocco fan is remarkably quiet as compared to an axial-flow fan, noises are suppressed to a low level.

Abstract: The invention provides a projector capable of reducing costs and promoting miniaturization while also being dust-proof. A second sirocco fan with an air-inlet opposing a projection lens is used, and an air-inlet of an outer case is formed on a side face thereof. Thereby, it is difficult for dust to be sucked therein compared with an air-inlet formed on the bottom or top face of the outer case, enabling the projector to be dust-proof without any filter. Since the filter is not required, the number of parts is reduced, thereby reducing costs. Furthermore, the second sirocco fan is placed by utilizing a space under the projection lens, which is liable to be a dead space, enabling the arrangement space to be efficiently used thereby promoting miniaturization of a projector.

Abstract: In a camera, a setting system sets a photographic factor representing a proper exposure, and a measurement system measures an actual photographic factor, corresponding to the set factor during a photographing operation. A determination system determines whether there is a coincidence between the set factor and the actual factor, and a recording system records the actual factor on a photographed frame of a photographic film when the determination system determines that there is the coincidence between the set factor and the actual factor. The recording system is constituted such that an error message is recorded on the frame of the film when it is determined that there is a non-coincidence between the set factor and the actual factor.
