摘要:
Storage performance in a charged state is improved in a non-aqueous electrolyte battery that contains 10 volume % or more of γ-butyrolactone, which is highly safe and reliable, as a solvent. A non-aqueous electrolyte secondary battery has a positive electrode containing a positive electrode active material composed of a lithium-containing transition metal oxide containing lithium and cobalt, a negative electrode, and a non-aqueous electrolyte solution composed of a solute and a solvent. The solvent contains 10 volume % or more of γ-butyrolactone with respect to the total solvent, and the positive electrode active material contains a Group IVA element and a Group IIA element of the periodic table.

A non-aqueous electrolyte secondary battery has a positive electrode containing a positive electrode active material, a negative electrode, and a non-aqueous electrolyte solution in which an electrolyte is dissolved in a non-aqueous solvent. The positive electrode active material includes a lithium-containing transition metal oxide that releases oxygen during initial charge, and the non-aqueous solvent contains a fluorinated cyclic carbonate in which fluorine atoms are directly bonded to a carbonate ring.

摘要:
A processing method has been claimed for reducing the average wait time of requests in a queue in a system environment where garbage collection may occur. In the method, a computer system treats as a unit each request in a queue and a completion time of garbage collection that may occur at the time of processing the request, and processes requests preferentially and systematically in ascending order of the processing times of the units including the garbage collection times, thereby, reducing the average wait time of the requests. While, the computer system managing the queue knows the remaining amount of heap just before processing a certain request, the computer system statistically calculates in advance the amounts of heap to be consumed on a request type basis and holds the values. Accordingly, before processing a certain request, the computer system can predict whether or not the processing of the request will cause garbage collection, in consideration of the estimated heap consumption of the request and the remaining amount of heap in the memory.

To provide a conductive agent for a nonaqueous electrolyte secondary battery and the like, in which oxidative decomposition reaction of an electrolyte is sufficiently suppressed during charging and discharging under high-temperature, high-voltage conditions and thus the cycle characteristics under these conditions are improved.A conductive agent main body composed of carbon and a compound attached to a surface of the conductive agent main body are contained. The average particle size of primary particles or secondary particles of the conductive agent main body is larger than the average particle size of the compound and the compound contains at least one metal element selected from the group consisting of aluminum, zirconium, magnesium, and a rare earth element.

A method, system and computer program product for optimally allocating objects in a virtual machine environment implemented on a NUMA computer system. The method includes: obtaining a node identifier; storing the node identifier in a thread; obtaining an object identifier of a lock-target object from a lock thread; writing a lock node identifier into the lock-target object; traversing an object reference graph where the object reference graph contains an object as a graph node, a reference from the first object to a second object as an edge, and a stack allocated to a thread as the root node; determining whether a move-target object contains the lock node identifier; moving the move-target object to a subarea allocated to a lock node if it contains the lock node identifier, and moving the move-target object to the destination of the current traversal target object if the lock node identifier is not found.
