A method of producing a microstructured gel in a shape in accordance with a pattern comprises: dropping a polymerizable monomer aqueous solution containing a polymerizable monomer component onto a portion of a surface of a substrate having a pattern comprising a fine groove in the surface; moving by capillary action the polymerizable monomer aqueous solution along the groove constituting the pattern; and subjecting the polymerizable monomer aqueous solution in the groove to polymerization.

In a video signal recording/reproducing apparatus capable of outputting as a reproduced video signal a video signal which has been recorded in advance, a cuttable portion detection section detects a cutting portion in the received video signal while recording a received video signal. A cuttable portion identification section identifies whether or not a reproduced video signal reproduced from a storage device belongs to the cuttable portion detected by the cuttable portion detection section. A switch judgment section receives a result of detection by the cuttable portion detection section and a result of identification by the cuttable portion identification section, and gives an output switch section an instruction to switch a video signal to an output switching section when the switch judgment section judges that the reproduced video signal and the received video signal are contained in the same cuttable portion.

In a video signal recording/reproducing apparatus, a video signal is subjected to bit rate reduction including a variable length processing to obtain a coded data. The coded data is separated into basic data which shows a basic construction of video image and has a fixed data length and additional data which shows detailed information of the video image and has a variable data length. In recording the coded data containing basic data and additional data on a recording medium, the basic data is recorded in one region on the recording medium and the additional data is recorded continuously in a region other than the basic data recording region, by which both data are recorded in separated regions on the recording medium.

A discharge exciting excimer laser device comprises a pair of main discharge electrodes, a dielectric and an auxiliary electrode. The dielectric is in a cylindrical form and has a side opposed to one of the main discharge electrodes, which side is formed into a flat plate-like portion. The auxiliary electrode is embraced within the dielectric leaving a space and is opposed to one of the main discharge electrodes with the flat plate-like portion of the dielectric sandwiched therebetween. Such a construction increases laser output and improves insulating performance.

A scanner device includes a scanner body enclosed by a housing and an external cover covering an outer side of the housing. The external cover is comprised of a plurality of external members. By spacing the adjacent external members apart from each other at the side edge parts of the housing, recesses are formed between the adjacent external members so as to constitute parts of the external design of the scanner body. Preferably, the side edge parts of the housing are exposed between the adjacent external members at the side edge parts of the housing, and information providing devices providing information on the scanner device are provided at the side edge parts of the housing exposed between the adjacent external members.

A filter device includes a vertical NR process portion, a vertical resolution conversion portion and a vertical NR process decision portion. The vertical NR process portion receives a horizontal NR processed signal and produces an NR processed signal. The vertical resolution conversion portion includes a plurality of resolution conversion filters and uses the NR processed signal to perform a vertical resolution conversion. The vertical NR process decision portion decides whether or not the vertical NR process portion should perform the vertical NR process on the horizontal NR processed signal in accordance with a resolution conversion filter selection signal for selecting one of plurality of resolution conversion filters for the vertical resolution conversion portion.
摘要:
An audio/video synchronous playback device includes a first synchronization section for repeating or skipping a first video data sequence in units of a video frame interval thereof to synchronize the first video data sequence with an audio data sequence, and a second synchronization section for repeating or skipping a second video data sequence in units of a video frame or video field interval thereof to synchronize the second video data sequence with the audio data sequence. A first video data sequence output and a second video data sequence output having different frame frequencies are separately synchronized with one channel of audio data sequence output with their respective precisions.

A filter device includes a vertical NR process portion (14), a vertical resolution conversion portion (12) and a vertical NR process decision portion (20). The vertical NR process portion (14) receives a horizontal NR processed signal (26) and produces an NR processed signal (27). The vertical resolution conversion portion (12) includes a plurality of resolution conversion filters and uses the NR processed signal (27) to perform a vertical resolution conversion. The vertical NR process decision portion (20) decides whether or not the vertical NR process portion (14) should perform the vertical NR process on the horizontal NR processed signal (26) in accordance with a resolution conversion filter selection signal (32) for selecting one of plurality of resolution conversion filters for the vertical resolution conversion portion (12).
