摘要： The disclosed camera power control devices operate with a camera in which a first switch responds to initial movement of a shutter release member, and a second switch responds to further movement of the release member. In the power control device, turning the first switch on energizes the light metering and display circuits, and turning on the second switch supplies an exposure control circuit such as a shutter control circuit with electrical energy. The power control device is provided with an electrical timer circuit, and a selection arrangement operates to selectively actuate the timer circuit when the release member is returned to its rest position and the first switch changes is state from ON to OFF. During a period of time determined by the timer circuit, power continues to be supplied to operate the light metering and display circuits.

摘要： A void space or region is formed within a camera body to protectively enclose a circuit board which controls the operation of the camera. Openings are formed to allow electric circuits and parts located outside of the region to be electrically connected to the circuit board. The openings are sealed with connecting terminals or seal members to tightly close or seal the region. Water, dust and the like are thereby prevented from entering the camera body from outside, and corrosion of essential electrical parts thus is avoided.

摘要： Disclosed is a multi-stage hydrogen water isotopic exchange column suitable for use in producing heavy water. It comprises, at each stage, an overlying vapor-and-water contact bed, an underlying catalyst bed and means for collecting the water dripping from the overlying contact bed and guiding to and sprinkling the water on the upper-surface of the vapor-and-water contact bed of the lower adjacent stage.The vapor-and-water contact bed consists of a closely compacted fine network structure, and the water dripping from an overlying contact bed is transferred through the catalyst bed via water channel and is sprinkled over the upper-surface of the vapor-and-water contact bed of the lower adjacent stage. With this arrangement a multi-stage exchange column according to this invention is guaranteed little amount of gas pressure loss and elimination of water splashing which otherwise would be caused by increasing the flow rate of hydrogen gas.

摘要： A photometric circuit for a camera including a first operational amplifier with a photo-electric element connected between its inverted and non-inverted input terminals and, a logarithmic compression diode connected between the output terminal and the inverted input terminal of the first operational amplifier, thus providing a voltage corresponding to the logarithmic value of the brightness of an object to be photographed at the output terminal of the first operational amplifier.A second operational amplifier has a plurality of temperature compensating commonly polarized diodes connected in parallel between its inverted input terminal and the output terminal. A first constant voltage is applied to the non-inverted input terminal of the second operational amplifier while a second constant voltage is applied through a resistor to the inverted input terminal of the second operatonal amplifier, thereby providing temperature-compensation of the output voltage of said first operational amplifier.

摘要： In the camera disclosed, an electromagnetic actuator is responsive to a timing pulse of short duration from an exposure control circuit for controlling the closing movement of a shutter. A permanent magnet may accidently be left latched and hold the rear curtain in cocked position after the timing pulse because of possible damage to an electromagnetic control circuit as a result of a battery short circuit. This may cause the film to fog during subsequent winding or rewinding. To prevent this, an indicator produces a visible indication either in the field of view of the camera finder or, in the case of remote shutter operation, outside the camera housing, that the rear curtain must be manually unlatched.
