An optical ring system having: a wavelength demultiplexer to which wavelength-multiplexed optical signal to be sent through an optical fiber from a previous node of multiple nodes is input and in which optical signal with each wavelength assigned to itself is demultiplexed; an optical ring device which is disposed in a predetermined node of the multiple nodes to the each wavelength assigned and which is composed of a failure existence judging part which terminates an overhead of each optical signal with a wavelength demultiplexed by the wavelength demultiplexer and judges whether a failure occurs in regard to a wavelength in a previous section through which optical signal with the assigned wavelength is sent, and a switching part which, when the failure existence judging means determines the occurrence of failure, selects a path that allows optical signal with the wavelength to be transmitted to the previous node while avoiding the previous section incurring the failure; and a wavelength multiplexer which multiplexes optical signal to be output from the optical ring part and then outputs it to an optical fiber connected to a next node.

The present invention provides a VP protection system and a VP protection method which forward messages quickly to nodes on an ATM network when an error occurs on the ATM network and reduce an error recovery time. The VP protection system, for use on an ATM network that includes a plurality of ATM nodes performing protection, a plurality of working VPs, and a plurality of standby VPs, exchanges messages among ATM nodes when an error occurs, one group of VPs at a time. An intermediate ATM node in a standby path at least comprises a VPG resource information management table, a VP resource information management table, a VPG configuration information management table, a VPG switching message receiving circuit, a VPG switching message sending circuit, node resource management circuits, a VPG resource allocation circuit, a VP expansion circuit, and a VP resource distribution circuit.

The ratio is calculated between a first number of pixels and a second number of pixels on an image sensor. The first number of pixels is counted between two certain points projected on the image sensor from a first section of a plane. The second number of pixels is counted between two certain points projected on the image sensor from a second section, adjacent to the first section, of the plane. The number of pixels between two certain points increases if the image sensor gets closer to the plane, while the number of pixels between two certain points decreases if the image sensor gets remoter from the plane. The inclination of the image sensor can be determined relative to the plane based on the ratio between the two numbers of pixels. The attitude or inclination of the image sensor can in this manner be detected with a high accuracy.

Disclosed is a configuration to implement a robot replacement in a library apparatus while maintaining an electrically-activated state. In such a configuration, the library apparatus storing a recording medium (cartridge) for writing and reading information with a host computer, comprises a plurality of robot units, which carries the recording medium; and a control unit (library control unit) which stops power feeding to the robot units if an event is generated until processing time of the event or predetermined time elapses and which transmits to a query from the host computer a response representing that the processing of the event is in progress.

摘要:
The present invention provides a novel compound having a GPR40 receptor function modulating action, which is useful as an insulin secretagogue, a drug for the prophylaxis or treatment of diabetes and the like. A compound represented by the formula (I) wherein each symbol is as defined in the specification, a salt thereof and a prodrug thereof have unexpectedly superior GPR40 receptor agonist activity and also show superior properties as a pharmaceutical product, such as stability and the like. Thus, they can be safe and useful drugs for the prophylaxis or treatment of GPR40 receptor related conditions or diseases in mammals.
摘要:
First and second mobile carriers are accessible to individual cells defined in a storage. The first and second mobile carriers move along overlapped paths. First and second controller circuits are connected to the first and second mobile carriers, respectively. The second controller circuit is also connected to the first mobile carrier. Even when a defect occurs in the first controller circuit, the transport mechanism allows the second controller circuit to take over the control on the first mobile carrier from the first controller circuit. The control on the first mobile carrier serves to avoid interference between the first mobile carrier and any obstacle on the path. If the first mobile carrier is removed from the path of the second mobile carrier, the second mobile carrier is allowed to keep operating. The operation of the transport mechanism can be kept without any interruption.

Radio tags storing parts identifying information are arranged for the individual constituent modules such as tape drives and conveying robots of the library apparatus. Upon every rise of the apparatus, the conveying robots are moved to positions permitting read of the radio tags arranged on the individual constituent modules. The parts identifying information such as the serial number is read by the tag reader and stored in the non-volatile memory. When this is different from the serial number read in the preceding run, stored in the non-volatile memory, it is determined that the part has been replaced. The statistical information of the number of operating runs is then cleared, and management of the parts service life is started.

Disclosed is a magnetic disk apparatus including a magnetic reproducing head portion, and a magnetic recording head including an upper magnetic core having a end portion and a rear portion. As a resist for a frame which is used for forming the rear portion, a negative resist or an electron beam resist is used, whereby the frame is formed without any adverse effect of halation from a coil insulating film. That is, it is possible to manufacture a magnetic recording head in which the rear portion of an upper magnetic core is not emerged at the face opposed to a medium, and hence to obtain a magnetic disk apparatus exhibiting an areal recording density of 5 Gbit/in2 or more by mounting a magnetic recording/reproducing head including such a magnetic recording head.
