Title: Thermal recording material
Inventor: MARUTA KEIICHI
IPC: B41M5/40
Filed: 1984-05-09
Abstract: PURPOSE:To provide a thermal recording material having excellent transparency, by incorporating polyvinyl alcohol and silica in a retouching layer. CONSTITUTION:The retouching layer applied to the surface of a thermal color forming layer comprises polyvinyl alcohol as a binder and silica as a filler. Water-soluble polyvinyl alcohol having a molecular weight of 15,000-150,000 is preferably used. Particulate silica, particularly, having an average diameter of 0.2-10mum is preferably used. Silica is used in an amount of preferably 0.4- 0.8pts.wt. per 1.0pts.wt. of polyvinyl alcohol. Accordingly, since silica is used as a filler in the retouching layer, transparency is not deteriorated when the amount of the filler is increased to enhance retouchability. In addition, since polyvinyl alcohol is used as a binder, an effect on enhancing the reprinting speed on a diazo duplicator can be obtained.

Abstract: PURPOSE:To quickly set the device in a state capable of measurement without any change of the set position of a laser beam generation device for vibration detection and its beam receiver by relaying the laser beam for the vibration detection on route. CONSTITUTION:When visible radiation S is emitted on a reflection mirror of a reflector 30 from a laser Doppler vibration measurement device 11, it is reflected to reach up to a suspended insulator body 6. Here, the reflected radiation S irradiates to reflect on the mirror 34 and returns to the device 11. This is confirmed by the use of a CCD camera 29 and a monitor television set TV. In the case where a strong reflection point on the body 6 is unclear and the like, a joy stick circuit is handled to adjust the inclined angle and the horizontal position of the mirror 34 and the reflection point is introduced to the proper position of the body surface. Next, when a laser beam for the vibration measurement from the device 11 is irradiated on the reflection point, the reflected laser beam surely returns to the device 11. In this state a suspended insulator 5 is vibrated by the use of a pulse laser beam generator to perform the measurement without any modification of the position of each device of emission and receiving.

Title: Optical modulator
Inventor: TOMITA AKIHISA
IPC: G02B6/12
Filed: 1990-04-09
Abstract: PURPOSE:To obtain an optical modulator which has a high extinction ratio and a small insertion loss by constituting a waveguide layer as a well layer where InAs and GaAs are laminated as one atom as the unit and a barrier layer of InA As or InP. CONSTITUTION:A waveguide layer 14 has a multiple quantum well structure which has a super-lattice, where InAs and GaAs are alternately laminated with one atomic layer one by one is used as a well layer 141 and has InAlAs or InP as a barrier layer 142, and an electric field is applied to this waveguide layer 14 by a p-side electrode 18 and an n-side electrode 19. Since the well layer 141 has the super-lattice where InAs and AlAs are alternately laminated with one atomic layer as the unit, local fluctuation of the composition does not occur, and the spectrum width of excitons is narrowed. Since the lattice oscillation in the lamination direction is suppressed in the super-lattice where the period is about one atomic layer, the coupling constant between excitons and the lattice oscillations is reduced to narrow the spectrum width of excitons. Therefore, a high extinction ratio and a small insertion loss are obtained.

Abstract: PURPOSE:To obtain the titled copolymer excellent in heat resistance and transparency by adding a methacrylic acid monomer to the system in the initial stage of polymerization and forming a styrene/methacrylic acid copolymer by effecting suspension polymerization at a specified monomer/water ratio. CONSTITUTION:In the production of a styrene/methacrylic acid copolymer comprising 95-75wt% styrene-based monomer and 5-25wt% methacrylic acid monomer by suspension polymerization, said suspension polymerization is performed in such a manner that the ratio of the monomer used to water falling within the range of 1/3-1/7 is selected and the methacrylic acid monomer is added to the system in the initial stage of polymerization. It is preferable to use a dispersant (e.g., partially saponified polyvinyl alcohol) in order to disperse said styrene/methacrylic acid monomer in water. An emulsion polymerization inhibitor (e.g., sodium nitriate) is used to prevent fine styrene/methacrylic acid copolymer powder from being formed and to increase the yield and the productivity.
