  • Patent number: 11222182
    Abstract: A receiving unit (310) receives a message transmitted from any one of the users that are talk targets. The interpreter (341) attempts to interpret, as an answer to a question, the message received by the receiving unit (310). A collector (342) collects, upon success of the attempt made by the interpreter (341), the interpreted answer as the answer from the user who sends the message. When a predetermined requirement is satisfied in a state where a yet-to-respond user whose answer is not yet collected by the collector (342) is present, an inquiry transmitter (321) transmits an inquiry about the question to at least the yet-to-respond user among the users. A result transmitter (322), after the answers are collected from all of the users, transmits to the users a message indicating a result obtained by tallying the answers.

  • Patent number: 7547868
    Abstract: An optical near-field generating apparatus includes a conductive scatterer causing an optical near-field based on a surface plasmon to be generated by being illuminated by incident light, and a conductive body arranged in a vicinity of the scatterer and generating a surface plasmon by being illuminated by the incident light and by being influenced by the surface plasmon of the scatterer. An oscillation direction of the surface plasmon of the conductive body is approximately parallel to an oscillation direction of the surface plasmon of the scatterer, and a generation region of the surface plasmon of the conductive body exists in a position deviated from a region extending in an oscillation direction of the surface plasmon of the scatterer.

  • Patent number: 7454771
    Abstract: An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed.

  • Patent number: 7420892
    Abstract: A compact and light flying head type magneto-optical head apparatus is provided. The magneto-optical head apparatus (1) of the present invention comprises a suspension (12) whose one end is fixed to a lower surface of an arm (11), a slider (13) fixed to a free end of the suspension (12), and a magnetic modulation coil (14) and an object lens (15) mounted on the slider (13). The slider (13) mounted with the magnetic modulation coil (14) and the object lens (15) floats due to a wind pressure caused by rotation of an MO disk (3). The magneto-optical head apparatus (1) is further provided with a collimeter lens (21) between a light source (71) and the object lens (15) in a hybrid optical apparatus (7) provided to the arm (11), and a position of the collimeter lens (21) can be adjusted vertically along an optical axis O-O by a collimeter actuator (23), so that optical conditions between the light source (71) and the object lens (15) are improved.

  • Patent number: 7064906
    Abstract: An optical pickup device and optical disc apparatus of the present invention include an optical element that prevents the incidence of light on unnecessary portions of the optical element so that stray light and noise are eliminated. The optical element include at least one substrate having a plurality of lens substrates that have embedded lenses made of a material with a higher refractive index than the at least one substrate. A shielding means limits the optical path so that incident light propagates only within a prescribed optical path formed on a light incidence-side or emission-side surface of one of the lens substrates. In addition, the shielding means is formed from an absorptive or reflective film placed in a region outside the prescribed optical path or through machining the region outside the prescribed optical path.
