Abstract: A lightweight viewing assembly for viewing horizontally aligned or vertically arranged stereo images shown on planar panels, particularly those shown on display monitors of computer systems and TV sets is disclosed, which includes a pair of reflector units for directing the sight of each eye toward spaced apart stereo images, a spectacle unit for bearing the reflector units, and a pair of adapter units as an interface between the spectacle unit and the reflector units for directing the sight of each eye toward vertically spaced apart stereo images. Attachment means enables the reflector units and the adapter units to be firmly attached to the spectacle unit and flexibly movable for adjusting the sight of each eye to obtain the best stereoscopic visual quality.

Abstract: A portable telephone charger has a charging seat, a connection wire, a first plug, and a second plug. A transformer is disposed in the charging seat. A cell chamber is formed on the charging seat. A connection socket is formed on the charging seat. A plurality of inner wires are disposed in the charging seat to connect the transformer and the cell chamber. The first plug is inserted in the connection socket. The connection wire is connected to the first plug and the second plug.

Abstract: A device for cleaning static precipitator in which hot air and steam are repeatedly filled into an oil-collecting sink of the static precipitator at different times or at the same time for heating and melting the oil dirt attaching to the static panels, making the oil dirt drop down into a collecting section. The static panels can be harmlessly cleaned up without disassembly or using any scraper. Hot air also serves to shorten the drying time for the static panels.
