An analysis chip comprises a thin film layer, which is formed on a dielectric material block and has two different regions. A flow path unit comprising a supply path for supplying a sample onto the thin film layer and a discharging path for discharging the sample is releasably loaded into the analysis chip. A light beam is irradiated to a first interface between one region of the thin film layer and the dielectric material block, and a second interface between the other region of the thin film layer and the dielectric material block, in a parallel manner. Refractive index information with regard to a substance to be analyzed, which is located on the thin film layer, is acquired from intensities of the light beam totally reflected from the first interface and the light beam totally reflected from the second interface.

Analysis method and apparatus and analysis unit

There is prepared a printing plate on which a material being hydrophilic due to light energy at a first temperature and being hydrophobic at a second temperature due to heat energy which is lower than the first temperature is provided. First, the whole surface of the printing plate is forcibly made either one of hydrophobic or hydrophilic. Next, a region having the other nature out of hydrophobic and hydrophilic is formed so as to correspond to an image to be printed. Then, ink is supplied onto the region having hydrophobic nature to conduct offset printing.

Offset printing method and printing apparatus using heat and light to make a printing plate hydrophilic and hydrophobic

A plate-making method is capable of recording a sharp image on a photosensitive plate, and is applicable to a process operation executed in a light room, while adverse influences caused by laser flares can be hardly received. Ultra-short pulse laser light emitted from a Ti:AlOlaser light source is modulated by an AOM (acousto-optic modulating element). The modulated laser light is focused by a collective lens onto a high-sensitive photopolymer layer of a photosensitive plate-making material. The focused ultra-short pulse laser light may cause a photopolymerization reaction in a laser-light-irradiated portion of the high-sensitive photopolymer layer by way of a multiple photon absorption phenomenon, so as to form a hardened portion.

Plate-making method, plate-making apparatus used in such plate-making method, and image recording material

Disclosed herein is a measuring apparatus equipped with a plurality of measuring units. Each measuring unit includes a dielectric block, a thin film layer formed on the dielectric block, and a sample holding mechanism for holding a sample on the thin film layer. The measuring apparatus is further equipped with an optical system for making a light beam enter the dielectric block at an angle of incidence so that a total internal reflection condition is satisfied at an interface between the dielectric block and the thin film layer, and photodetectors for measuring the intensity of the light beam totally reflected at the interface. The optical system is constructed so that light beams simultaneously enter the dielectric blocks of the measuring units. The number of photodetectors corresponds to the number of the light beams.

Measuring apparatus and measuring chip

Disclosed herein is a sensor utilizing attenuated total reflection. The sensor is constructed of a measuring chip, an optical system, and a measuring section. The measuring chip is equipped with a dielectric block, a thin film layer formed on the dielectric block, and a liquid-sample holding portion for holding a liquid sample. The optical system is used to make a light beam enter the dielectric block at various angles of incidence so that a total internal reflection condition is satisfied at an interface between the dielectric block and the thin film layer. The measuring section measures the state of attenuated total reflection, based on the intensity of the light beam totally reflected at the interface. The liquid-sample holding portion has an opening at its top surface. The sensor further has a lid supply mechanism for placing a lid on the opening to prevent evaporation of the liquid sample.
