摘要:
An iron comprising a water tank, a blast unit, a steam generating unit and a steam spraying unit. The blast unit has a first inlet and a first outlet, the first inlet is connected to the inlet-pipe of the inlet of the water tank, wherein the blast unit generates steam rapidly in a limited space. The steam generating unit has a second inlet and a second outlet, the second inlet being connected to the inlet-pipe of the inlet of the water tank, wherein the steam generating unit heats the water to generate steam. The steam spraying unit connects the first and second outlet, has plural steam apertures, and sprays steam. Because a blast unit is arranged for the rapid steam generation in a limited space, the iron of the present invention obviates the disadvantages in the existing irons and improves steam blast strength, intensity at a low cost.

In general, a wavelength division multiplexed (WDM) communication system simultaneously pre-filters and combines groups of wavelengths with orthogonal polarizations to provide a pre-filtered, pair-wise orthogonal aggregate WDM optical signal. In particular, an orthogonally-combining interleaving filter multiplexer provides substantially orthogonal polarizations for odd and even channel wavelengths and simultaneously pre-filters and combines the orthogonally polarized odd and even channel wavelengths using interleaver optics. The orthogonal polarizations may be provided by orientation of PM input fibers or by a polarization rotator in the orthogonally-combining interleaving filter multiplexer.

In general, a wavelength division multiplexed (WDM) communication system may use wavelength selective switching to simultaneously pre-filter and combine groups of channel wavelengths with orthogonal polarizations to provide a pre-filtered, pair-wise orthogonal aggregate WDM optical signal. An orthogonally-combining wavelength selective switch (WSS) multiplexer may route channel wavelengths individually from different sets of channels to a common output. The orthogonally-combining WSS multiplexer may also provide substantially orthogonal polarizations for the wavelengths in the different sets of channels. The different sets of channels may include odd channels and even channels.

Disclosed are a form template definition method and a form template definition apparatus. The form template definition method comprises a cell extraction step of analyzing an image of a form so as to extract one or more cells from the image of the form; a cell classification step of classifying the extracted cells; and a cell attribute definition step of defining attributes of the extracted cells class by class. If an attribute of a first cell in one class is defined, then other cells in the class automatically copy the attribute of the first cell. As a result, the work amount of form template definition may be dramatically reduced by employing the form template definition method and form template definition apparatus.

The productivity of a catalyst in a gas phase polymerization of olefins (e.g. grams of polymer per gram of catalyst) may be increased by including in the gas phase from 1 to 20 weight % of an inert non-polymerizable hydrocarbon. The hydrocarbon may be in gaseous form but preferably is in liquid form.
摘要:
A discharge lamp lighting control device (100) having a DC power converter, a power factor improving power converter (1), a polarity reversing circuit (2), a starter circuit (3), and a controller (4). The power factor improving power converter 1 includes a switching device S, a power factor improver, and a power converter. The power factor improver operates to smooth a rectified voltage by storing energy in a first inductive device L1 and by discharging energy from a second inductive device L2, in which the first and second inductive devices are magnetically coupled together. The storing and discharging is performed by turning ON and OFF the switching device S. A predetermined DC voltage is converted by energy stored and discharged by a third inductive device L3 in response to the turning ON and OFF of the switching device S.
