IPC: G11B7/00
Filed: 1992-10-19
Abstract: PURPOSE:To execute appropriate access for a sector on a track by making the control possible whether tracking is performed along a track on a spiral shape track or the tracking is performed by keeping an existing track. CONSTITUTION:When the command of the write/read of data from a host computer is issued, a temporary purpose sector is set. Then, the track jumping sector is set before by 1 sector or 2 sectors than the temporary sector. The process is executed by an optical disk controller 41. Then, a sector address where a head is placed present is read. Then, whether a head arrives at the sector before by 1 track than a target track or not is checked, and when not, the head is seeked or jumped by a difference. When arrives, a track keep control signal (c) is outputted from an optical disk controller 41 to a drive controller 42. Then, the device 42 executes write/read operation.

IPC: G01T1/167
Filed: 1991-10-24
Abstract: PURPOSE:To monitor whether radioactivity leaks or not from a primary to secondary system in any of a plurality of steam generators. CONSTITUTION:Radioactivity of a secondary system coolant passing through main steam pipes from steam generators to a steam turbine is detected and a radiation dose detected in the main steam pipes 13a, 13b and 13c is integrated to judge whether the integrated value thus obtained is maintained within a reference value determined based on such a degree of radioactivity level that appears attributed to the background radiation. Objects to be detected of radiation detecting means 14A, 14B and 14C are the secondary system coolants existing before mixed with or diluted into the secondary system coolants of other secondary systems loops to improve detection accuracy. When there is no abnormality with the absence of leakage of radioactivity and changes in the background, an integrating function by a detection value integration/signal transmission switching means 19H provides a replacement as a handy measuring system thereby achieving a higher processing speed thereof as well.

Title: Light amplification module
Inventor: SHIKII SHIGERU
IPC: G02F1/35
Filed: 1988-12-06
Abstract: PURPOSE:To decrease the number of components and adjustment positions and to reduce light loss by using a narrow-band interference filter. CONSTITUTION:High-output exciting light 111 from a light source 11 for excitation is passed through a collimator lens 12 and reflected by the narrow-band interference filter 15 to pass through the collimator lens 16, thereby entering a long-sized transmission optical fiber 17. Signal light which is propagated in the fiber 17, on the other hand, enters the filter 15 through a lens 16. Therefore, the light 111 and signal light coexist in the fiber 17 and the signal light is amplified by Raman scattering with the light 111. Then the amplified signal light in multiple light is transmitted through the filter 15, the majority of the exciting light except a component nearby the signal light frequency is reflected by the filter 15, and the amplified signal light enters the fiber 13 through a lens 14. A multiplexer demultiplexer is not necessary as compared with a case wherein a multiplexer demultiplexer and a narrow-band filter are used to decrease the number of components and adjustment points, thereby reducing the light loss.
