摘要： PROBLEM TO BE SOLVED: To provide an apparatus for measuring a gas concentration which can stably obtain data without variations. SOLUTION: The apparatus detects by an optical detecting part optical information obtained from a chemical reaction between a gas to be measured and a chemical substance, and obtains a concentration of the gas from the optical information. A casing 1 of the apparatus has downward opening parts (slits 2) which let in a gas containing the gas to be measured into the casing 1, and at the same time, prevent an external light from entering the casing 1. The concentration of the gas to be measured can accordingly be measured without being affected by the external light.

摘要： PURPOSE:To provide a bright color display which is easily produced by using a photosetting resin as a high-polymer material of a display material. CONSTITUTION:An optical element is constituted by forming a multilayered structure composed of the high-polymer material 605 consisting of a photosetting resin and a liquid crystal 606 between transparent electrodes 603 and 604 formed on substrates 601, 602. Since the refractive index of the liquid crystal 606 is changed by an electric field, the changing of the refractive indices of the liquid crystal 606 and the high- polymer material 605 is possible. The multilayered structure in which the difference in the refractive index between the high-polymer material 605 and the liquid crystal 606 is generated is obtd. if the voltage is not applied. Light 609 of a specific wavelength band among the incident light 608 is reflected and the light of the other wavelengths is obtd. as transmitted light 610 by the optical properties of the multilayered structure. The multilayered structure is dissipated when the difference in the refractive indexes between the high-polymer material 605 and the liquid crystal 606 is decreased by applying the voltage and changing the refractive index of the liquid crystal 606. The incident light 608 is then obtd. as it is as the transmitted light 610. Then, the reflection/transmission of the light of the specific wavelength band are electrically controlled.

摘要： PURPOSE:To reduce manufacturing cost and to miniaturize a device by forming a heating unit which is heated by an electric current in a first substrate, forming a conductor in a second substrate, and sandwiching high polymer scattering type liquid crystal between the first substrate and the second substrate. CONSTITUTION:A heating wiring 11 is formed as a heating unit in a first transparent substrate 18, a heating power source 13 is connected to the heating wiring 11, and a heating control switch 14 is provided between the heating power source 13 and the heating wiring 11. Also, a electric field applying wiring 12 is formed as a conductor in a second transparent substrate 19, a signal generator is connected to the electric field applying wiring 12, and the heating wiring 11 and the electric field applying wiring 12 intersect perpendicularly. And a high polymer scattering type liquid crystal 16 is sandwiched between the transparent substrate 18 and the transparent substrate 19. Therefore, since the high polymer scattering type liquid crystal 16 is used, orientation processing is not required and manufacturing cost is inexpensive, and since a heating head or a laser beam is not required to be used as a heating source, a display device can be miniaturized.

摘要： PURPOSE:To attain a television(TV) telephone set or a TV conference terminal capable of allowing visual lines to coincide with each other through a screen without expanding the size of a device or deteriorating display resolution. CONSTITUTION:An image pickup element 13 is arranged so as to consider a display face 14 and a hologram 12 for reflecting only the light of a specific wavelength and converging the light to the element 13 is arranged in the front of the display face 14. Only the light of the specific wavelength out of light reflected by a transmitter 11 is reflected by the hologram 12 and made incident upon the element 13. On the other hand, the light of the specific wavelength out of light projected from the face 14 displaying a receiver is reflected by the hologram 12 but the light of other wavelengths is passed through the hologram 12 and reached to the transmitter 11. Consequently the transmitter and the receiver can interact each other while observing the front faces of opposite speakers. Since the hologram 12 is like a thin film and has no shape to be recognized, display resolution is not deteriorated and compact size can be also attained.

摘要： PROBLEM TO BE SOLVED: To obtain a liquid crystal film which can be processed according to the user's desire, which is flexible and cut into any shape and which can be driven at low voltage by sandwiching a mixture with two transparent conductive films while the conductive faces face each other. SOLUTION: A liquid crystal and a polymer network substance such as a UV curing resin are weighed, to which plastic beads or glass beads as a spacer are added in a small amt. and mixed to prepare a liquid crystal mixture 8. Then the liquid crystal mixture 8 is applied on a transparent conductive film 5 produced by forming a transparent conductive layer 2 such as an ITO film on the film surface of polyether sulfone or the like. The films are stacked with the transparent conductive layers 2 facing each other. Thus, the liquid crystal mixture 8 is held between the two transparent conductive films 5. The laminate is irradiated with UV rays while uniformly pressurized on both sides by using glass plates 9, pressurizing clips 10 or the like.

摘要： PROBLEM TO BE SOLVED: To prevent colors from fading for a long time and obtain a molded form which does not easily get dirty, by forming a layer containing a metal oxide having a photocatalyst function on the surface of the molded form. SOLUTION: A non-solvent paint in which metal oxide particles having a photocatalyst function are mixed, is applied to the inner wall face of a mold, in a molding method of a resin molded form 1. A molten resin is injected in the metal mold and metal oxide particles are transferred to the resin 2 side. The resin molded form 1 provided with a layer 3 containing metal oxide at the cooled and solidified surface is separated. Titanium dioxide having a large photocatalyst action is favorably used. Titanium dioxide is classified to rutile and anatase types depending on the crystalline form and the anatase type has a larger photocatalyst action than the rutile type. The photocatalyst action of metal oxides is accelerated by addition of a trace of iron, niobium or the like into a metal oxide, or mixing of an ultraviolet ray absorbent.

摘要： PURPOSE:To increase the intensity of reflected light and to make display with high visibility by clamping a PDLC layer which selectively reflects only the right-hand circularly polarized light and a PDLC layer which selectively reflects only the left-hand circularly polarized light between substrates formed with electrodes. CONSTITUTION:This display/recording medium includes the high-polymer dispersion type cholesteric liquid crystal (PDLC) layers which are formed by dispersing the cholesteric liquid crystals or chiral nematic liquid crystals into high polymers and are alternately changed to a selective reflection state to reflect the circularly polarized light of a specific wavelength and a state not reflecting the circularly polarized light. The display/recording medium described above is formed by clamping the dextrorotatory PDLC layer 11 which selectively reflects only the right-hand circularly polarized light and the levorotatory PDLC layer 12 which selectively reflects only the left-hand circularly polarized light between one set of the substrates 5 formed with the transparent electrodes 4. As a result, the reflection of both circularly polarized light rays is made possible, the number of the reflection surfaces by the substrates and the electrodes and absorption of light are decreased and the high intensity of the reflected light is obtd.
