Title: Ktiopo4 single crystal and its production
Inventor: OKAMOTO TSUTOMU
IPC: C30B29/22
Filed: 1992-12-29
Abstract: PURPOSE:To provide a KTiOPO4 single crystal capable of growing a high-quality single crystal in which a sufficient single domain is formed and a method for producing the single crystal. CONSTITUTION:A KTiOPO4 raw material is melted with a flux to prepare a melt, which is used to produce a single crystal of the KTiOPO4 according to the so-called top seed solution growth(TSSG) method. In the process, the molar fractions of K2O, P2O5 and TiO2 contained in the melt are kept within an area surrounded by 6 points of A, B, C, D, E and F in the ternary constitutional diagram. At this time, K15P13O40 or a substance capable of providing the same composition by melting is used as the flux to provide the ratio of the KTiOPO4 composition accounting for 83.5-90.0mol% of the melt composition. Thereby, more stable crystal growth can be carried out.

Title: Wavelength separating element and manufacture of the same
Inventor: ITO MASAYA
IPC: G02B6/293
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To easily manufacture a wavelength separating device of uniform quality at a low cost by specifying the combination of a plurality of optical fibers and a lens. SOLUTION: When the light having the wavelengths λ1 and λ2 are injected to an end part A of a first optical fiber 1, the light of the wavelength λ1 is ejected from an end part B because a fiber grating 4 of a first fiber 1 is designed in such manner that it transmits the light of the wavelength λ1, and ejects the light of wavelength λ2 outside of the fiber. On the other hand, the light of wavelength λ2 is ejected outside of the first optical fiber by the fiber grating 4, and injected into a fiber grating 5 of a second optical fiber 2 by a lens 3. The light of wavelength λ2 entered into the fiber grating 5 is ejected from an end part C of the second optical fiber 2.  The wavelength λ1 is injected from the end part B and the wavelength λ2 is injected from the end part C by the reversibility of the light, whereby a device can act as a wavelength combining device for ejecting the light of the wavelengths λ1 and λ2 from the end part A.

Title: Antenna system
Inventor: HIRABE MASAJI
IPC: H01Q21/06
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To simplify and miniaturize structure. SOLUTION: When an electromagnetic wave is supplied to a first micro strip antenna 104, the first micro strip antenna 104 resonates and radiates the electromagnetic wave into air. Since a second micro strip antenna 106 is electro- magnetically connected to the first micro strip antenna 104 through the opening 8 of a ground board 4, the second micro strip antenna 106 resonates to the first micro strip antenna 104 and radiates the electromagnetic wave into air in the same way as the first micro strip antenna 104. Consequently, a bi- directional characteristic or a non-directional characteristic can be obtained. Namely, power is needed to be fed only to the first micro strip antenna 104 in an antenna system 2 and therefore the power distributor of three-dimensional structure is not required as in a former case. Thus, the system can be simplified and miniaturized.

Title: Color filter and liquid crystal display device
Inventor: WATANABE TAKUO
IPC: C09B25/00
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To obtain color filters having excellent dependence on a visual field angle by including resins and retardation decreasing particles into any of red pixels, green pixels and blue pixels. SOLUTION: Retardation decreasing particles having double refractive indices with opposite positive and negative signs to those of a resin are added to the resin, by which the double refractive indices of the resin are compensated and the color filters having the small absolute value of retardation and the good characteristic of the visual field angle are obtained. Namely, the particles having the alignment nearly perpendicular to the alignment direction of the resins in colored films are incorporated into the resins when the resins, such as polyimide and polyamide, having the high alignment characteristic are used for the resins constituting the colored film of the color filter, by which the codes of the double refractive indices of the resins and the particles are reversed in the positiveness and negativeness from each other and the retardations of the colored films are decreased.  The retardation decreasing particles have >=2 plane structure groups and have such conformation that the face of the one plane structure group is perpendicular to the plane structure group of the other face, by which the particles are eventually provided with the polarization rate anisotropy of the two components.
