Abstract: An acid pickling tank 11 is filled with an acid liquid L, and a lid 12 is attached to the acid pickling tank 11. A central part of the lid 12 is depressed downwards to form a covering portion 12b. The covering portion 12b is located at a lower position than the liquid level of the acid liquid L in the acid pickling tank 11 to cover a free surface of the acid liquid L. Immersion guide rolls 20a to 20e are provided on the covering portion 12b, support blocks 21a to 21e are provided at the bottom of the acid pickling tank 11, and skids 23a to 23e are provided on the support blocks 21a to 21e via a bottom plate 22. Thus, the free surface of the acid liquid L in the acid pickling tank 11 is decreased to suppress a loss of the acid, and prevent an overflow of the acid liquid L to the outside of the tank, thereby making acid pickling of the strip steel plate S efficient.

Abstract: A camera in which the ratio of an object to the photographing frame can be set comprises a varifocal lens in which the in-focus position is changed in accordance with the change in the focal lens and a focusing lens for correcting the focus by the varifocal lens. The size of the object is set to the desired size by using the varifocal lens, and thereafter the deviation of the in-focus point is controlled by the focusing lens. Since the zooming is carried out by using a varifocal lens, a camera can be provided in which the ratio of an object to the photographing frame can be set in a simple structure.

Abstract: A camera capable of taking pictures selectively in a standard or full size frame and a panorama frame having a reduced vertical dimension. This camera includes vertically movable light-shielding members for partly light-shielding an exposure range of the standard frame to set an exposure range of the panorama frame. When the panorama frame is selected, a warning is given on a display provided on the camera body to the effect that a date and other photographic information cannot be recorded on pictures taken in the panorama frame. The shutter of the camera includes an electronic device for detecting an amount of light traveling from a photographic object to which light is flashed. Output of this device is used for suitably controlling exposure for photography in the standard and panorama frames.

Abstract: A camera system is capable of operating in a number of different photographic modes and includes a display system which provides information relevant to each of the modes. The camera system also includes an automatic film rewinding mechanism that has two modes of operation. In a first, automatic, mode, the tensioning of the film during winding is detected to indicate the end of the roll of film. Upon such detection, the film is automatically and fully rewound into the film cartridge. In a second, user selectable, mode a signal is manually provided by the user to initiate film rewinding. Rewinding of the film is stopped just prior to the time the end of the film enters the cartridge, so that a portion of the film leader remains extended outside of the cartridge.
