摘要： A lens tube guide frame holds a retractable lens tube in the body of the camera and also holds a lens and a film surface in their respective correct positions for making exposures. The lens tube guide frame can be easily inserted in the body of the camera and includes a standard surface at its front inner wall opposite the open side of the lens tube guide frame to provide an exact stop for forward movement of the lens tube. The guide frame cross section is U-shaped or box-shaped, and has two projection portions directed outwards at the open rear end to engage adjacent side walls of the camera body. The lens tube guide frame, with the lens tube already in it, is inserted into the camera body through the back side when assembling, whereby the lens tube guide frame can be positioned without any adjustment.

摘要： The battery charging detects battery temperature and includes a temperature maintaining charging operation wherein average charging current is controlled to drive battery temperature to a holding temperature, and charging is performed while maintaining battery temperature at that holding temperature. In addition, a temperature increasing charging operation occurs prior to the temperature maintaining charging operation. The battery is charged with a current which raises battery temperature until the holding temperature is reached. When battery temperature rises to the holding temperature in the temperature increasing charging operation, charging can transition to the temperature maintaining charging operation.

摘要： In order to make a thermal utilization system operable in a stable and efficient condition regardless the variation of the operating heat source used, the system is provided with three hydrogen absorbing alloys having different pressure-temperature characteristics, wherein absorption/desorption of hydrogen gas is performed in two steps, i.e. the hydrogen gas desorbed from a first alloy is absorbed by a second alloy at a predetermined pressure, and is absorbed by the third alloy at a higher pressure after it is desorbed from the second alloy in a case when the temperature of the operating heat source is low, while the hydrogen gas desorbed from the first alloy is directly transported from the first alloy to the third alloy to be absorbed there when the temperature of the operating heat source is high. Alternatively, two hydrogen absorbing alloys having different pressure-temperature characteristics are used in such a way that, when the temperature of the operating heat source is low, the hydrogen gas desorbed from the first alloy is pumped to the second alloy to be absorbed there, but the gas is directly transported from the first alloy to the second alloy to be absorbed there when the temperature of the operating heat source is high.
