Abstract:
A storage apparatus includes a storage unit and a controller, wherein control of inputting/outputting data from/to a device provided in said storage unit is executed in accordance with a request received by said storage apparatus. An actual device of the storage apparatus corresponds to a virtual device which is external to said storage apparatus. The controller operates to perform a process for mapping an actual device address corresponding to a virtual device address, in accordance with a specification of the actual device to be mounted or unmounted to correspond to the virtual device, and storing and retaining mapping information obtained from the mapping in a first table. The controller also performs data input/output process for receiving, an access request for data input/output in which said virtual device address is specified, obtaining the actual device address mapped to said specified virtual device address in said first table, and accessing the actual device by said obtained actual device address.
Abstract:
Provided is a heat device which heats and fixes a developed image onto a recording material while nipping and conveying the recording material bearing the developed image by a nip portion, in which even when a turn-on duty ratio between at least two heat generation members provided to a heat source is switched in a direction in which a maximum amount of possible heat generation is decreased, in order to suppress generation of a fixing failure of the developed image formed on the recording material due to a shortage of electric power, in a case where the turn-on duty ratio of a second heat generation member to a first heat generation member is switched, at a predetermined timing, in a direction in which the maximum amount of possible heat generation is decreased, with respect to the at least two heat generation members provided to the heat source, it is set as a condition that a turn-on ratio of the first heating member at the timing is smaller than a predetermined value.
Abstract:
A controller of a cantilever evaluation system calculates a stream function value ψz(x, y; t+1) and vorticity ωz(x, y; t+1) at a subsequent time step t+1 using boundary conditions according to displacement h(z; t) of a cantilever and velocity δh/δt(z; t), a stream function value φz(x, y; t) and vorticity ωz(x, y; t) in two-dimensional planes. The controller uses the calculated stream function value φz(x, y) and vorticity ωz(x, y) to calculate a fluid drag force acting on the cantilever. The controller substitutes the calculated fluid drag force into a displacement calculation equation to calculate the displacement h(z; t+1) of the one-dimensional beam at the subsequent time step t+1. The controller repeats such calculation for each grid point and further repeats it at each time step.

Abstract:
A technique is provided in which, even when the number of devices and device addresses handled in the storage apparatus side increases, it is possible to access all the devices and save used resources by simple control of the configuration definition information without adding the device addresses retained on the host side. The host side handles a virtual device for an access to an actual device handled on a storage apparatus side to retain a virtual device address, specifies an actual device to be mounted to the virtual device, and makes an access for data input/output by the virtual device address. A CHA of a controller maps an actual device address to a virtual device address and retains it in a table in a SM, and when receiving the access by the virtual device address, obtains the corresponding actual device address from the table to access the actual device.

Abstract:
An object of the present invention is to integrally manage disk storage apparatuses through virtualization. Some physical storage apparatuses 14 connected to a host computer 10 via a communication network 12 are virtualized with a virtual switch 18, a control unit 20, and a virtual device 22. The physical storage apparatus specifies a command when receiving the command from the host computer 10, and accesses, if the command access has been made to its own physical storage apparatus, a real disk via the virtual control unit 20 and virtual device 22, and executes I/O processing. If the command access is not made to its own physical storage apparatus, the physical storage apparatus 14 directs the command to the transmission target via the virtual switch 18. The physical storage apparatuses 14 are integrally managed according to the command in the above described manner.

Abstract:
An image generating apparatus is provided which can maximize the throughput without causing thermal damage of the fusing components. It determines a sub-thermistor temperature threshold value for switching small size paper feed intervals in response to a sub-thermistor initial temperature. It supplies a heating body with current for heating, and starts feeding recording mediums at the feed interval determined by a feed interval initial value. It makes a successively conveyed paper count. Every time the successively conveyed paper count reaches a paper count threshold value, it performs the switching control of the sub-thermistor temperature threshold value. If the sub-thermistor temperature exceeds the threshold value while the recording medium is passing through the fusing apparatus, it carries out the switching control of the feed intervals. In another mode, it prevents the extension of the paper feed interval of the paper conveyance during a specified paper count α.
