摘要： PURPOSE:To obtain a stable polymeric semiconductor or conductor composition of excellent film-forming property, by reducing a holomethyl aromatic compound into a polymer mainly consisting of specified aromatic recurring units. CONSTITUTION:A compound of formula I is reduced to obtain the title composition as a polymer mainly consisting of recurring units of formula II, wherein Ar is a group having a conjugated system, such as a linear aromatic compound, or a condensed aromatic compound, Z and Z are each a halomethyl group, the C-C bond is double or triple, X and X are each H or a halogen or null when the C-C bond is triple. Because the light absorption characteristics can be reversively changed by doping and dedoping, the polymer obtained by this process can be used as an electrode material, a magnetic shield material, an electrochromic material, a p-h junction element, etc.

摘要： PURPOSE:To obtain an electrochemical junction element which can be brought into a state of total solidification by a method wherein a film is formed on one high molecular material by electric polymerization by performing a cathodic reduction or an anodic oxidation method on the high molecular materials having different electrochemical potential. CONSTITUTION:The solution, formed by melting the glass on which an ITO film is formed on the anode in acetonyl together with cobaltisium salt and [(C4H9)4N] BF 4 in an electrolytic cell in which platinum is used on the cathode, is electrolyzed applying -2.0 V to a silver electrode, and a cobaltocene polymer film of 800 Angstrom in thickness is formed. The solution formed by synthesizing Fe(C5H4CHCH3Cl)2 by reacting Fe(C5H4CHCH3OH)2 with PCl3 in a nitrogen gas atmosphere and dissolved in benzene, is cast on the cobaltsen polymer film and a ferrocene film is formed, and a solid-state electrochemical junction element is formed by pressure-bonding ITO glass.

摘要： PURPOSE:To enable the simple coupling of a thin film optical guide and optical fiber with good efficiency by providing the optical fiber on the thin-film optical guide formed on a substrate and providing an ultrasonic wave transducer. CONSTITUTION:An optical fiber 7 of which the clad on the side face is polished away until the core exposes partly is provided on the thin-film optical guide 6 formed on a substrate 2, by being contacted at its polished portion. In addition to this, an ultrasonic wave transducer composed of a comb-type electrode 8 is provided on the optical guide 6. Light signal is then entered from one end A of the optical fiber 7, at the same instant of which the electrode 8 is excited to propagate the ultrasonic wave signal in the optical guide 6 in the same direction as its incident light wave. Changing the propagation constant of light through controlling of this ultrasonic wave signal enables the selectively and highly accurate photocoupling to the other transmission path 9 connected to one end B of the optical guide 6.

摘要： PURPOSE:To obtain the title polymer which consists of a polyyne skeleton, can show semiconductivity or conductivity when doped and is useful as a functional polymeric material, by reductively polymerizing an aromatic compound having trihalogenated methyl groups. CONSTITUTION:A monomer of formula I (wherein Ar is a conjugated system composed of linearly bonded aromatic compounds or condensed aromatic compounds and Z and Z are each a trihalogenated methyl) (e.g., a compound of formula II or III) is prepared. This monomer and an electrolyte (e.g., tetrabutylammonium tetrafluoroborate) are fed to an electrolytic cell together with a solvent and polymerized by electrochemical reduction. In this way, a semiconductive or conductive polymer mainly consisting of a skeleton of repeating units of formula IV can be obtained. This polymer is excellent in film-forming property, can form a stable film and is useful as an electrode active substance of a secondary battery, an electrochromic material or the like.

摘要： PURPOSE:To arbitrary adjust the phase constant between optical guides by providing a photsensitive thin film on one optical guide in the photocoupling part of the photocoupling device or in proximity thereto and forming the grating image which periodically changes the refractive index of light. CONSTITUTION:A photosensitive film 4 is provided on one optical guide 3 in the coupling place L or in extreme proximity thereto as shown in the figure. The control light from the outside is radiated to this photsensitive thin film 4 to expose the grating image corresponding to the control light to this. Arrangement is so made that the refractive index of light at this portion is periodically changed. These enable the arbitrary adjustment of the phase matching conditions between the optical guides 2 and 3 and the enhancement of the photocoupling efficiency.

摘要： PURPOSE:To eliminate the need for separately connecting the elements having the function of optical filters and optical fibers by packing photosensitive material in the contact portions of the optical fibers and forming a grating directly in the layer by making use of its photosensitive characteristics. CONSTITUTION:At least two optical fibers 8, 9 which are cut and ground of clad parts 6 by a suitable length to exposre core parts 7 are coupled at a coupling length L. A layer 10 formed with optical grating is interposed in the contact portion of the optical fibers 8, 9. In forming the grating in the layer 10, the laser beams 11, 12 which are sensitive to photosensitive material are entered to the layer 10 at 2theta0 in the angle assumed by both beams to sensitize the layer 10. At this time, the bright and dark interference fringe is produced along the lengtwise direction of the optical fibers 8, 9, as a result of which only the bright fringe portions are sensitized and the optical grating is thus made. In this way, the need for separate connection of the elements having the function of optical filters and optical fibers may be eliminated.
