摘要:
A lens-fitted photographic film unit has a flash device for emitting a flash of light. A charge switch is adapted to bring the flash device into an on-state, either by rotation of a film advancing wheel, or when a shutter device is cocked. When the flash device is in the on-state, a main capacitor is charged so as to allow emission of a flash of light. In a preferred embodiment, the charge switch is initially turned on so as to keep the flash device in the on-state. In another preferred embodiment, the flash device is in the on-state while the charge switch is on, and is in the off-state while the charge switch is off, in response to the shutter device. When the lens-fitted photographic film unit is contained in a wrapper, an insulating tape is inserted between a positive electrode of the battery and a contact segment. Upon the wrapper being torn off the lens-fitted photographic film unit, the insulating tape is pulled out of the lens-fitted photographic film unit, so as to bring the flash device into the on-state.

A waterproof casing contains a lens-fitted photographic film unit in a watertight manner so as to take underwater photograph. The waterproof casing is provided with an air flow opening. An air-permeable waterproof sheet is attached to the air flow opening form the inside so that air can pass through the sheet freely so as to regulate the internal pressure of the waterproof casing but water will not enter the waterproof casing. In a preferred embodiment, the waterproof casing consists of a transparent main body with a bottom opening and a bottom lid. The air flow opening is formed os as to be covered by a film winding knob of the waterproof casing. Structure to be fitted in the bottom opening is formed with another air flow opening to which the air-permeable waterproof sheet is attached. Outside this structure is disposed a waterproof sheet having an opening at a position facing the air flow opening of this structure. The waterproof sheet is covered by the bottom lid.

The present invention provides a thermoelectric conversion element, a thermoelectric conversion element module, and a method of manufacturing the same that can easily realize high-density arrangement of thermoelectric conversion elements and securement of connection reliability. The thermoelectric conversion element has, for example, rod-shaped thermoelectric conversion material, tube that has an insulation property and an adiabatic property and houses thermoelectric conversion material, and electrodes that are in close adhesion to the end surfaces of thermoelectric conversion material and tube. A surface roughness Ra of the end surfaces is larger than 0.8 micrometers. In the present invention, the thermoelectric conversion elements can be arranged at a high density such that tubes are in close adhesion to each other. Also, since the close adhesion surface of electrodes on the end surfaces is large, the connection reliability of electrodes is further improved.

The invention provides a thermoelectric conversion module, which can implement a high power generation capacity and high reliability of electric connection between thermoelectric conversion elements and meet various diameters and lengths of a tube as a heat source. The thermoelectric conversion module includes a straight-chain module unit. In the module unit, plural P-type elements and plural N-type elements, which are alternately arrayed, are electrically connected in series by a braided wire A and a braided wire B. The braided wire A connects one end surface of the P-type element and one end surface of the N-type element. The braided wire B connects the other end surface of the P-type element and the other end surface of the N-type element. The braided wire B is shorter than the braided wire A. The thermoelectric conversion module including only the module unit is spirally wound around a tube as a heat source.
