摘要： In an optical transmission network of the present invention, an optical signal output from a CWDM unit is combined on an optical transmission path of a DWDM network via a multiplexing filter arranged on a light output terminal of a DWDM unit adjacent to the CWDM unit. Furthermore, an optical signal propagated on an optical transmission path is branched from the DWDM light by a de-multiplexing filter provided on a light input terminal of an adjacent DWDM unit, and applied to a CWDM unit adjacent to the DWDM unit. As a result, it is possible to mutually connect a plurality of CWDM networks, using an optical transmission path of a DWDM network, and it is possible to realize a longer distance for CWDM networks.

摘要： A small-sized mobile radio has a built-in antenna is high enough to enhance the antenna characteristics. In the mobile radio, a base plate is structured by a section (antenna-housing section) including a supply portion and a short-circuiting portion, for example, of an antenna element which affect the antenna characteristics, and a section (circuit-housing section) which is the rest of the base plate. The antenna-housing section is so positioned so as to keep the built-in antenna high enough, that is, to keep the space between the base plate and the antenna element large enough. On the other hand, the circuit-housing section is positioned toward the back of the cabinet to provide room for a display and a key section.

摘要： The present invention relates to a process for recovering subliming substances, which deposit in the form of crystals, from a subliming substance-containing gas by combining a cooling operation for lowering the temperature of collecting tubes for the deposition of crystals below the temperature at which the crystals deposit with a heating operation for heightening the temperature of the collecting tubes above the temperature at which the crystals deposit. A subliming substance is continuously recovered in the form of crystals at a high ratio without suffering the recovered crystals from developing a color.

摘要： An automatic transmission has: a primary transmission mechanism including: an input shaft; a planetary gear set having a sun gear, planetary gears and a ring gear, each being a helical gear, the ring gear and sun gear being respectively connected to the input shaft and to a stationary member via a one-way clutch, and a carrier for the planetary gears is connected to a primary output shaft; and an centrifugal clutch engaged/released the input shaft with/from the primary output shaft in correspondence with a centrifugal force by a weight and a thrust force by the helical gear; and a secondary transmission mechanism connected to the primary output shaft, for controlling a gear-shift into two or more speed-changed conditions. A multiplicity of change-speed gears is obtained by selectively combining the released and engaged states of the centrifugal clutch for each of the speed-changed conditions of the secondary transmission mechanism.
