Abstract: Dual-wall container includes an outer wall that is at least one of at least partially substantially transparent and at least partially substantially translucent, an inner wall adapted to contain a substance, at least one symbol arranged an outer surface of the inner wall, and at least one of a coating of a thermochromatic composition arranged on the outer surface of the inner wall, a thermochromatic composition layer arranged on the outer surface of the inner wall, and a thermochromatic composition arranged on an outer surface of at least the at least one symbol. The thermochromatic composition is structured and arranged to change color when the inner wall experiences or senses a temperature change. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

Abstract: A retracting mechanism for a lens barrel, the mechanism includes a non-rotatable member having an engagement surface; a frame movable along an axis towards and away from the non-rotatable member without rotation and having a holder for holding an imaging element, the holder pivotally mounted to the frame for movement between an aligned position where the lens barrel component is aligned with the axis and a displaced position where the component is displaced relative to the aligned position; and a spring assembly configured to resiliently hold the holder at the aligned position and having an engagement surface configured to contact the engagement surface of the non-rotatable member during movement of the frame towards the non-rotatable member, overcome the resilient holding of the holder at the aligned position, and move the holder from the aligned position to the displaced position.

Abstract: An electro-developing type camera uses an electro-developing recording medium, and has a determiner for determining whether the electro-developing recording medium has been recorded on or not when being loaded in the camera, and a selector for selecting one of a photographing mode and an image-reading mode as an operation mode of the camera. A photographing operation is executed in the photographing mode to record and develop an optical image in the electro-developing recording medium. An image-reading operation is executed in the image-reading mode to read the developed image of the electro-developing recording medium. The photographing mode is selected by the selector when the determiner determines that the electro-developing recording medium has not been recorded, and the image-reading mode is selected by the selector when the determiner determines that the electro-developing recording medium has been recorded.
