摘要:
In order to make it possible to measure the light absorption coefficient of various sorts of substances contained in a light scattering material (18) with a high precision, a method is disclosed, by which wavelength of light (15, 23, 28, 34) transmitted through the light scattering material (18) is varied and the coefficient of light absorption (α) is calculated, starting from a ratio of variations in the intensity of the transmitted light to variations in the wavelength.

In a computer system including a disk subsystem (80) having channel interface (71) compatible to a count-key-data format and a SCSI interface (61) compatible to a fixed length data format, the disk subsystem (80) is connected to a CPU (10) controlled by an open system operating system (40) through the SCSI interface (61), and connected to an other CPU (11) controlled by a main frame operating system (50) through the channel interface (71). The CPU (10) is provided with a CKD record access library (35) and a VSAM access library (30) which accesses in a FBA format the VSAM record stored by the other CPU (11) in a CKD format in the disk subsystem (80) and allows the access by an application program (20) of the CPU (10) as a VSAM record based on VSAM control information.
摘要:
A storage system (80) is connected with a first computer (11) and a second computer (10) and comprises a first interface (71) for receiving first data in a count-key-data format from the first computer (11), a storage device (100) for storing the first data, and a second interface (61) compatible with a fixed length data format, for receiving a request for reading the first data from the second computer (10) and outputting data stored in a track storing the first data to the second computer (10). The request includes information sent from the first computer (11) to the second computer (10) and indicating the position in the storage device (100) where the first data is stored.
摘要:
A multi-point measuring apparatus of FBG sensor has an optical fiber 4, a wide-band wavelength light source 9, a light-source side light modulator 10 for controlling time of a light entering into the optical fiber 4, among lights from this light source, a detector side light modulator 12 for controlling time, during which a reflection light from a diffraction grating of the optical fiber 4 penetrates through, a wavelength shift amount calculator 14 for processing a signal obtained through detection of the reflection light from this light modulator, so as to separate a signal from the optical fiber 4, a temperature/distortion calculator 15 for calculating an amount of deformation of a target to be measured from a result of this calculator, and a display portion 16 for displaying information relating to the amount of deformation of this target to be measured, and thereby providing a multi-pint measuring method and an apparatus of FBF sensor, enabling to measure the FBG sensors of plural pieces of optical fibers, without using an optical switch therein, even under the condition of applying the plural pieces of the optical fibers in one (1) piece of a transmission path.
