A captured video image obtaining unitobtains a captured video image in which a player making a golf swing is captured. A swing path type specifying unitspecifies at least one reference angle based on at least one of a position of a predetermined body part of the player at address or a position of a shaft at address, where the positions are specified based on the captured video image. A swing path type specifying unitspecifies a downswing angle of a club head captured in a captured video image based on the captured video image. The swing path type specifying unitcompares the reference angle with the downswing angle.

Golf swing analysis system, golf swing analysis method, and information storage medium

A receiving unit () receives a message transmitted from any one of the users that are talk targets. The interpreter () attempts to interpret, as an answer to a question, the message received by the receiving unit (). A collector () collects, upon success of the attempt made by the interpreter (), 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 () is present, an inquiry transmitter () transmits an inquiry about the question to at least the yet-to-respond user among the users. A result transmitter (), after the answers are collected from all of the users, transmits to the users a message indicating a result obtained by tallying the answers.

Server device, servicing method, and program

A recording/reproduction apparatus includes: a light source; and a near-field light production section that includes two conductor sections disposed opposite each other with a predetermined gap therebetween and that produces near-field light between the two conductor sections upon light irradiation from the light source, the two conductor sections being disposed such that when information is recorded on a recording medium using the near-field light, a direction from one of the two conductor sections to the other of the two conductor sections is generally perpendicular to a line direction of the recording medium.

Recording/reproduction apparatus and recording/reproduction system

An optical near-field generating device is provided. The optical near-field generating device includes: a light source; a light transmissive substrate; and a conductive scatterer irradiated with light from the light source to generate an optical near-field. The scatterer is formed across planes with different heights on the light transmissive substrate and includes a first area formed on a surface closest to an object to which the optical near-field is applied and a second area formed on a surface distant from the object as compared with the first area. The optical near-field is generated from the first area of the scatterer toward the object.

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.

Optical near-field generating apparatus and method and information recording and reproducing apparatus

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. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.
