Abstract: An aperture covering including track-guided interconnectable panels that are compactly stored in a storage area containing weight counterbalancing mechanisms, such as a compressed spring, is described. When the panels are stacked in the storage area and removed one at a time, the first panel is removed from the storage area and enters the track. As the first panel moves through the track, it interlocks with the second panel and forces the second panel out of the storage area and into the track. Interlocking and removal of the panels continues until all of the panels are removed or the first panel reaches the end of the track. Weight counterbalancing can be assisted by track-contained toothed belts, cable and ball drive mechanisms, or other counterbalancing methods. The resulting aperture covering requires minimal storage space for the open aperture position, minimizes exposure to potentially hazardous counterbalancing mechanisms, and allows for heavy-weight panel construction.

Abstract: In an accumulator cycle, lubricating oil containing polyalkylene glycol (PAG) as a main component is used for a hermetic electric compressor. Lubricating oil mixed with refrigerant (carbon dioxide) can exhibit electric insulation resistance that causes no problems on a practical use. Since PAG has low compatibility with respect to carbon dioxide, a large amount of liquid phase refrigerant is difficult to be sucked into the compressor while being dissolved in lubricating oil. Therefore, the efficiency of the compressor is not lessened.

Abstract: A process for manufacturing synthetic quartz glass involves feeding a quartz glass-forming raw material to a high-temperature gas zone within a chamber, converting the quartz glass-forming raw material into quartz soot, and forming synthetic quartz glass from the soot.
