摘要： A video super-resolution device includes a down-sampler, video super-resolvers, and a selecting/averaging unit. The down-sampler divides an input low-resolution video into a plurality of frame rates. The video super-resolvers are video super-resolvers trained at different frame rates, and perform super-resolution of the low-resolution video. The selecting/averaging unit selects a video super-resolver according to the magnitude of an optical flow obtained as a result of video super-resolution. Specifically, in a case where the optical flow has a value smaller than 0.5 pixels, the selecting/averaging unit makes selection such as not adopting a result of video super-resolution at a high frame rate. Finally, the selecting/averaging unit obtains a mean value of the selected video super-resolution result, and outputs a final high-resolution video.

摘要： A laser apparatus includes: a light source configured to generate laser light; and an optical negative feedback unit configured to narrow a spectral line of the laser light using optical negative feedback. A modulation signal is input to the light source to modulate a frequency of the laser light. A modulation amount in the frequency of the laser light is detected. A modulation sensitivity is calculated from (i) the modulation amount and (ii) an intensity of the modulation signal.

摘要： Provided are a carbon nanotube production device and production method capable of realizing high-temperature heating of a catalyst raw material in a floating catalyst chemical vapor deposition (FCCVD) method, and improving the quality and yield of carbon nanotubes synthesized. A carbon nanotube production device 1 includes a synthesis furnace 2 for synthesizing carbon nanotubes; a catalyst raw material supplying nozzle 3 for supplying a catalyst raw material used to synthesize carbon nanotubes to the synthesis furnace 2; and a nozzle temperature adjusting unit 6 capable of setting a temperature of an inner portion 4 of the catalyst raw material supplying nozzle 3 higher than a temperature of a reaction field 5 of the synthesis furnace 2. By supplying to the synthesis furnace 2 the catalyst raw material that has been thermally decomposed after being heated to a temperate at which a catalyst metal will not yet be condensed, and by having the thermally decomposed catalyst raw material rapidly cooled to a CVD temperature at the synthesis furnace 2, microscopic catalyst metal particles will be generated at a high density in the space of the reaction field 5 such that carbon nanotubes having a small diameter can be vapor-grown at a high density.
