摘要:
It is an object of the present invention to provide molecular compounds useful in the fields of state-of the-art materials, such as formulations, waste water treatments, energy transducers, conductors and bio-model reactions, in a way that interaction points and forces working inside polymer assemblies are fixed as well as controlled so that constituent polymers are aligned and modified. It is also an object of the present invention to provide methods for aligning and/or modifying polymers having hydrogen bond sites. A molecular compound is produced from a tetrakis aryl compound represented by Formula (I) (wherein, X is (CH2)n, or p-phenylene; n is 0, 1, 2 or 3; Y is hydroxyl, carboxyl or optionally substituted amino: and R1 and R2 are each hydrogen, lower alkyl, optionally substituted phenyl, halogen or lower alkoxy) and a polymer having hydrogen bond sites, such as polyethers, polyalcohols or polyamines.

There are provided a method of detecting dispensed quantity in which without the need of detecting a surface of liquid accommodated in a container, a liquid quantity can be detected only by measuring pressure change; and a relevant liquid suction monitoring dispensing apparatus. There is provided a method of detecting dispensed quantity for detection of the quantity of liquid suctioned and discharged by a dispensing apparatus including a pipette tip, a liquid suctioning/discharging mechanism for the pipette tip, a pressure sensor capable of detecting the pressure within the pipette tip, and a lifting and lowering mechanism for the pipette tip, which method comprises: an insertion step for inserting a distal end of the pipette tip down to the deepest zone of a container accommodating liquid to be measured; a suction pressure measuring step for without moving of the pipette tip, while suctioning the liquid into the pipette tip at a predetermined suctioning rate, measuring any pressure change during the suctioning; and a suction detecting step for on the basis of pressure change measured, determining the state of suction. Further, there is provided a liquid suction monitoring dispensing apparatus capable of practicing this method.

A storage system includes a plurality of disk drives, one or more controller boards for controlling data read and write from/to the plurality of the disk drives, and a Fibre Channel switching board for controlling path switching between the controller boards and the plurality of the disk drives. The Fibre Channel switching board has a control logical circuit for adjusting a control signal system between the controller boards and the disk drives according to a connection confirmation signal indicating whether or not the control signal cable is connected to the Fibre Channel switching board.

The storage control device of the present invention detects faults on the disk drives at an early stage, thus enhancing convenience of use. The disk drives are switchingly connected to a subordinate communication control unit via a switching circuit. An error information collection unit of an error monitoring unit detects errors which have occurred at each port of the switching circuit. The errors which have been detected are stored in an intermediate storage unit, and are input via an error information notification unit to a fault recovery control unit of the subordinate communication control unit. By doing this, it is possible to immediately specify whether or not a fault has occurred on any of the disk drives, and to start a fault recovery procedure.

A method of processing Ethernet signals for transport in an optical network system is disclosed. The method includes encapsulating Ethernet frames into EFP frames comprising a length header, a converged data link header, and a data area, and mapping the EFP frames into byte synchronous paths. The converged data link header replaces an Ethernet preamble of the Ethernet packet.

The power supply device of the present invention supplies power highly reliably by suppressing an increase in costs even when a multiplicity of load groups are present. When operating normally, each of the normal power supply units supplies power via a normal path to each of the load groups. One redundant power supply unit is provided for a plurality of normal power supply units. When any of the normal power supply units fail, the redundant power supply unit continues to supply power to the load group via the redundant path. A diode for connecting the redundant path to the normal path is provided in each normal power supply unit and the redundant paths that are routed through the respective normal power supply units are connected so as to intersect one another between the normal power supply units.
摘要:
A method is provided to point out which software program is causing a problem. Event records are collected from target objects being monitored. An event group is then produced by grouping the collected event records. The event group is compared with a plurality of pattern definition groups in terms of occurrence patterns of event records, where each pattern definition group defines a pattern of event records that would be produced upon occurrence of a particular problem. Subsequently a troubleshooting record is extracted. This troubleshooting record has previously been associated with a pattern definition group resembling the event group in terms of occurrence patterns of event records.
