摘要： PROBLEM TO BE SOLVED: To make it possible to describe much information in a product of a small area and to manage processes without using a host computer by preparing plural materials of which reading methods are mutually different as components, multiplexing code patterns corresponding to process management information, writing the multiplexed code patterns on the surface of a product, and reading out the written information. SOLUTION: Ink or toner is prepared by using plural materials of which reading methods are mutually different as respective components. Code patterns such as two-dimensional bar codes corresponding to information required for process management are multiplexed and written on the surface of a product by a printer 2 such as an ink jet printer connected to a computer 1 for inputting information. These code patterns are read out by a reader 3 and displayed on a computer 4 to execute process management. Coloring materials, a transparent material (e.g. a fluorescent coloring matter) and a transparent material for emitting near infrared rays by visual light or heat are used for these materials.

摘要： PROBLEM TO BE SOLVED: To provide a recording medium which can deal with a high recording speed and enables high precision and high density recording by incorporating an org. compd. recording material consisting of such a compd. that has at least two reactive positions in the molecule which absorb light in a specified wavelength region and can produce a dimer with another molecule, and that the molecules in the crystal structure are arranged to have an optically active part when the dimer is produced. SOLUTION: A compd. expressed by the formula is used as a recording material. In the formula, X1 is a disubstituted aromatic ring or heteroring, Y1 is a monosubstituted aromatic ring or heteroring, and R is a monosubstituted alkyl group. The optical recording medium containing this material is irradiated with patterned light in a specified wavelength range to produce dimers. The recording and reproducing method includes a writing process of information to cause rotary polarization in the irradiated part, and a reading process to read out the written information by mapping the rotatory degree of the medium to detect a part having optical rotatory and a part not having optical rotatory.

摘要： PROBLEM TO BE SOLVED: To obtain an optical circuit which is capable of easily aligning the usable wavelength of an optical function element, such as an optical amplifier, to an optical waveguide, such as a plastic optical fiber, is easily producible and is easy to handle by incorporating org. dyestuff into the photo-oxide of polysilane of an optical function element. SOLUTION: The org. dyestuff is incorporated into the photo-oxide of the polysilane of the optical amplifier 14 in the optical circuit having the optical waveguide 13 and the optical amplifier 14 which is the optical function element connected to this optical waveguide 13. While the polysilane used here is not particularly limited, the polysilane having the repeating units expressed by general formulas I to III is more preferable. In the formulas I to III, R denotes a substd. or unsubstd. hydrocarbon group; R denotes a substd. or unsubstd. hydrocarbon or acyl group; R denotes a substd. or unsubstd. sillyl group or polysilane skeleton.

摘要： PROBLEM TO BE SOLVED: To control the distribution of silicon nanocrystal particle size in gas phase by irradiating a silicon oxide containing silicon nanocrystal with a laser light of specified wavelength in an atmosphere containing oxygen and oxidizing the surface of silicon nanocrystal of such size as absorbing the laser light thereby controlling the particle size thereof. SOLUTION: Silicon nanocrystal having interband pumping energy lower than the energy hν of laser light is oxidized to reduce the particle size thereof substantially. When the particle size decreases furthermore, the interband pumping energy of silicon nanocrystal increases gradually and at a moment of time when it exceeds the hν, the laser light is not absorbed nor the oxidation proceed. When a laser light having wavelength of 500nm or less is used, particle size of the silicon nanocrystal can be arranged at 5nm or less.

摘要： PURPOSE:To provide the optical wavelength converting element which has a high conversion efficiency and does not require the processing of uncoverted light of an incident fundamental wave by shutting the fundamental wave, which is made incident on a waveguide part, in the waveguide part to allow it to resonance so that it is not radiated out of the optical wavelength converting element. CONSTITUTION:A waveguide part 1 consisting of a nonlinear optical material, a waveguide support part 2 which is arranged as one body together with the waveguide part 1, and a reflecting film 3 which is arranged as one body on both end faces in the guiding direction of the waveguide part 1 and reflects the fundamental wave made incident on the waveguide part 1 are added to make a resonator of the optical wavelength converting element. Thus, the power of the fundamental wave is accumulated in the resonator, and the efficiency of conversion to the second or third harmonic wave is considerably improved. Since the incident fundamental wave is shut in the waveguide part 1, the postprocessing of unconverted light in the fundamental wave is unnecessary.
