Abstract: A seismic reinforcement device for a bridge includes a first member having a projecting portion and a second member having a depressed portion. The device has a horizontal force sharing function in which the projecting and the depressed portions are freely fitted to and engaged with one another to constitute a shear key and resist a horizontal force by causing the first member to be coupled to and supported by any one of the substructure and the superstructure and causing the second member to be coupled to and supported by the other of the substructure and the superstructure. In addition, the device has a level difference preventive function that suppresses dropping of the superstructure and reduces a level difference of the substructure and the superstructure by interposing a spacer having a predetermined thickness between the first and second members or between the substructure or the superstructure and the device.

Abstract: [Problems] To provide a monomethine dye compound that enables formation of a thin film with high refractive index and excellent optical properties through formation of a homogeneous thin film of dye molecule J-association complex by easy means (spin coating technique) and that has high sensitivity and excels in short mark recording capability so as to be suitable for high speed recording and high density recording, and further to provide an optical information recording medium utilizing the monomethine dye compound and a process for producing the same.
