Abstract: Polymer particles are provided which contain fluorescent molecules with high presence ratio in a polymer layer thereof and a method for preparing thereof. Polymer particles are swelled in a non-aqueous solution excluding exclusively water preferably promotes selling of the polymer layer and transfer of the fluorescent molecules to the polymer layer could not protected by water molecules such that much more fluorescent molecule may be introduced into inside of the polymer layer. Furthermore, since the water is added to the reaction system prior to evaporation removal of the non-aqueous solvent, dry-up of the polymer particles is prevented by the water remained in the reaction system and the polymer particles including fluorescent molecules with high presence ratio of the fluorescent molecules preferably keep high dispersibility using the above described procedures.

In an affinity reaction of biosensing, ligands are immobilized to magnetic fine particles and the magnetic fine particles are forced to reaction fields of the affinity reaction by magnetic guiding so as to bring the affinity reaction, which is the velocity controlling factor in the sensing, to high rates. According to the present invention, coated magnetic fine particles with having both of the high dispersion performance and high magnetic responsibility as the above described magnetic fine particles and the affinity reaction occurs quickly and in high density such that the present invention makes it possible to obtain relatively large signals within significantly short time duration when compared to the conventional art.

Abstract: Nano-sized inorganic particles having uniform particle sizes and precisely controlled particle diameters have already been produced by synthesis in an organic solvent, but these nano-sized inorganic particles are hindered from dispersing in a polar solvent because of the adsorption of a long-chain fatty acid on the surfaces of the particles. Further, it was difficult to form nano-sized inorganic particles dispersible in a polar solvent by replacing the long-chain fatty acid coats.

Each of the switch units comprises a circuit substrate having a required circuit pattern formed to include a plurality of pairs of short-circuiting possible land portions, and a switch mounted on the circuit substrate so that any one of the plurality of pairs of land portions are short-circuited selectively to set a switching function inherent to that switch unit. Any one selected from the switch units is mounted in one of the unit mounting sections, and the switch of that switch unit is turned on. A switch unit decision section constituting a control section detects the land portions short-circuited to automatically make a decision about the kind of a switching function of the mounted switch unit.

Abstract: An optical head used for recording/reproducing information signals for an optical disc having a light transmitting layer on a recording layer includes an actuator for the collimator lens. A collimator lens arranged between a light source and an objective lens is moved by the actuator for the collimator lens in a direction of cancelling the spherical aberration ascribable to thickness errors in the light transmitting layer. By this structure, the amount of generation of spherical aberration is reduced even if the numerical aperture NA of the objective lens loaded on the optical head is increased to render it possible to increase the recording capacity of the optical disc.
