摘要： The present invention aims at providing a technique capable of supervising and controlling optical repeaters, without affecting transmission characteristics and wavelength bands of signal lights, by utilizing the Raman effect. To this end, the present invention provides a supervisory controlling system of an optical repeater, in an optical amplifying-and-repeating transmission system for amplifying and repeatingly transmitting signal light propagated through an optical transmission path by the optical repeater, wherein the supervisory control signal light is amplified due to the Raman effect by the signal light acting as excitation light in an optical transmission path (Raman amplifying medium), to thereby supervise and control the optical repeater in accordance with the thus Raman amplified supervisory control signal light.

摘要： An optical disk 100 is provided with a hub 3 at the central portion of a substratel. A relationship Y/X≧0.015, preferably Y/X≧0.05 is satisfied where X is the projected area of the substrate 1 and Y is a contact area between the hub 3 and the substrate 1. As result, no slippage occurs between the hub 3 and the substrate 1 even when they are rotated at high speed than conventional. With this higher rotational speed, the data transfer rate is improved, and irregular rotation and the camming are suppressed, thereby reducing tracking errors and write/read errors.

摘要： An information write/read head writes or reads information on or from recording tracks by the heat-assisted system. The information write/read head includes a magnetic head provided in such a manner that a longitudinal direction of a magnetic gap crosses a scanning direction. Further, the information write/read head includes an aperture slit having a length of not less than a diffraction limit of a light beam, and a width shorter than the diffraction limit in the direction orthogonal to the recording track, which is formed in such a manner that the longitudinal direction thereof is aligned in a scanning direction of the recording track.

摘要： An optical sample includes a mask layer made of a material in which an aperture is produced by a chemical change, which is reversible, upon application of heat or light, and a recording layer provided at a position where an evanescent field produced in the aperture when light is applied to the mask layer can reach. Since the aperture is produced in the mask layer by a chemical change, it can be opened and closed at a high speed and hence a high-speed transfer of information can be achieved.

摘要： A disc cartridge includes a disc casing having a disc chamber defined therein for rotatably accommodating the recording medium. The disc casing has a sensor hole and a slot defined in first and second wall portions of the casing that are opposed to each other. A safety device is disposed within the disc casing for preventing information recorded on the erasable recording medium from being erased inadvertently. The safety device includes a bearing bushing integral with the first wall portion, and a switching element connected at one end rotatably with the bearing bushing for angular movement between first and second operative positions. The sensor hole is adapted to be closed by the switching element when the latter is angularly moved to the first operative position.

摘要： In flow detection by a thermal-type flow measuring instrument, a flow rate valve with reduced measurement error due to temperature variation can be obtained even under environment where a fluid temperature and a circuit temperature are different. A measurement error due to temperature variation of the fluid of the thermal-type flow measuring instrument can be corrected on the basis of a temperature of the fluid by adjusting the measurement error to be constant ratio irrespective of the flow rate. On the other hand, a temperature characteristic of the circuit is adjusted to be substantially zero %.
