摘要:
In each node of an optical transmission system: an optical preamplifier has an ALC function for maintaining an optical output level constant and an AGC function for maintaining the gain constant; the operational mode of the optical preamplifier is changed from an ALC mode to an AGC mode after the gain is set in the ALC mode; an optical postamplifier has an AGC function; an optical switch unit performs an optical crossconnect operation; and a thru-light-shutoff control unit makes a switch setting so as to shut off pass-through light in the optical switch unit and stop transmission of an optical signal having an unstable level to a next stage when the optical preamplifier operates in the ALC mode, and clears the switch setting when the operational mode of the optical preamplifier is changed to the AGC mode.

Gain setting of a receiving amplifier, is performed by detecting the necessity of gain setting when a receiving amplifier is turned on, requesting WDM transmission equipment in a preceding station to output ASE light; in a WDM transmission equipment of the preceding station, shutting off both passing-through light and added light, and outputting the ASE light corresponding to a predetermined number of wavelengths of signal light; in the receiving amplifier of the WDM transmission equipment in the station of interest, performing the gain setting by use of the ASE light; and on completion of the gain setting, the WDM transmission equipment of the station of interest, requesting the WDM transmission eouipment of the preceding station to halt the ASE light output, and the WDM transmission equipment of the preceding station, halting the ASE light output upon receiving the request and switching the output to an optical signal output.
摘要:
The present invention relates to a toner for electrophotography which has a small particle size and is excellent in all of low-temperature fusing ability, anti-hot offset property and image characteristics and a process for producing the toner, as well as to a dispersion of crosslinked resin particles which is used for production of the toner for electrophotography and a process for producing the dispersion of crosslinked resin particles. The dispersion of crosslinked resin particles having a volume median particle size (D50) of from 0.05 to 0.7 μm according to the present invention is produced by a process including the steps of (A) neutralizing a resin containing an acid group-containing polyester in an aqueous medium to obtain a dispersion of resin particles; and (B) mixing the dispersion of resin particles obtained in the step (A) with an oxazoline group-containing polymer at a temperature of from 60 to 100° C.

A plating method for pre-plating or plating a cylinder inner peripheral surface to be treated of a cylinder block by introducing treatment liquid to the cylinder inner peripheral surface by using a plating apparatus provided with a sealing jig having a sealing member and an electrode to which the seal jig is mounted includes the steps, which are performed successively: sealing the cylinder inner peripheral surface by bringing the sealing jig into contact with the cylinder inner peripheral surface; introducing the treatment liquid to the cylinder inner peripheral surface; and treating the cylinder inner peripheral surface by applying predetermined charge to the electrode of the plating apparatus and the cylinder block to thereby perform pre-plating or plating process in a state that a liquid to be treated fills a space including the cylinder inner peripheral surface. In the method, the treatment liquid introducing step is performed after confirmation of sealing by the sealing step.

摘要:
When a user indicates a point on a display screen of a computer using a pen sensor, first the display screen is divided into a plurality of areas and the areas are displayed by mutually different colors or brightnesses. The plurality of colors or brightnesses displayed are scanned by the pen sensor and the colors or brightnesses detected by the light receiver to judge in which area the indicated point is located. Next, the judged area is further divided into a plurality of areas which are displayed by mutually different colors or brightnesses. Next, a routine similar to the above is successively repeated to narrow down the area in which the point indicated by the pen sensor is located and finally determine the position of the point, that is, the XY coordinates on the display screen.
