  • Publication number: 20240126616
    Abstract: A computation processing device includes: a convolutional computation unit that sequentially outputs convolutional computation result data; a pooling processing unit including a pooling computation circuit and a non-volatile storage circuit for pooling, in which the non-volatile storage circuit for pooling retains the convolutional computation result data or a computation result of the pooling computation circuit, as retained data, and the pooling computation circuit calculates and outputs pooling data subjected to pooling processing to a pooling region by using the retained data each time when the convolutional computation result data is input from the convolutional computation unit; and a power gating unit that blocks power supply to the non-volatile storage circuit for pooling while waiting for the input of the convolutional computation result data from the convolutional computation unit.

  • Publication number: 20210165676
    Abstract: A technique is provided for performing shutdown of a virtualization system. A control unit of a server may be configured with instructions to perform operations comprising operation as a first management unit that manages shutdown of a plurality of virtual machines that operate on a hypervisor, and a second management unit that, when all of the virtual machines are shut down, shuts down the server, and the first management unit, upon acquiring information indicating that shutdown of a virtual machine is completed, executes shutdown of another virtual machine.

  • Patent number: 9085116
    Abstract: A method for manufacturing a honeycomb structure includes: preparing a base material sheet; forming a plurality of strips by forming a plurality of slits parallel to each other at regular intervals in the base material sheet; twisting each of the strips around an axis along which the strip extends; temporarily forming a plurality of cell areas defined by the strips by temporarily, partially bonding each of the twisted strips to another strip adjacent thereto; and completing the form of the cell areas by performing permanent bonding on the temporarily bonded portions by inserting a mold into the temporarily formed cell areas and heating the strips.

  • Patent number: 7330990
    Abstract: Based on information that is transmitted to a UPS communication part by UPSs connected to an information processing apparatus, a UPS monitoring part monitors the states of the UPSs. A UPS control part employs the monitoring results to generate control information for controlling the state of at least one of the UPSs, and permits the UPS communication part to transmit the control information to the UPS that is to be controlled. The present invention can be applied for a computer having a redundant power supply function.

  • Publication number: 20050052805
    Abstract: A UPS monitoring part monitors a state of a UPS, on the basis of an information which was transmitted from the UPS which was connected to an information processing apparatus, and received by a UPS communication part. A UPS control part, on the basis of a result of that monitoring, generates a control information for individually controlling respective states of a plurality of electric power output parts of the UPS, in accordance with a condition of power-off of each load which was connected to the corresponding electric power output part, and carries out a control for transmitting it from the UPS communication part to the UPS.

  • Patent number: 6317697
    Abstract: An apparatus for determining life of a battery which supplies charged electricity to an electrical appliance is equipped with a storage part for storing relationship between standard total values of discharge voltage drop amounts since a start of discharge of the battery and standard life values, a discharge voltage drop amount totalizer part for totalizing the discharge voltage drop amounts since the start of discharge with the battery being discharged, and a life determination part for determining the life of the battery from a measured total value of totalized discharge voltage drop amounts and the standard total values of the storage means.

  • Patent number: 5987420
    Abstract: The present system comprises a device which issues tickets, a central processing device and an entrance gate device which controls entry to the site. The central processing device establishes appropriate data representing the maximum carrying capacity of each attraction (i.e., the maximum number of reservations which can be given out). It does so by performing a fuzzy inference based on fuzzy rules using as fuzzy variables various uncertainty factors which influence cancellations and other events that transpire after a reservation is made, such as type of attraction, weather, time of day, day of the week and season.

  • Patent number: 4198369
    Abstract: A process for lining container caps, which comprises applying a dispersion in an aqueous medium of an olefin resin to the inner bottom surface of a cap shell, subjecting the aqueous dispersion applied to a first-step heat treatment at a temperature below the thermo-forming temperature of the olefin resin, and then subjecting it to a second-step heat treatment at a temperature not lower than the thermo-forming temperature of the resin but below the heat decomposition temperature of the resin.
