Abstract:
Provided are a non-reciprocal unit used for a polarization dependent type optical isolator and a polarization dependent type optical isolator that are simple in structure, can prevent damages due to light and heat and can obtain a high extinction ratio. In a polarization dependent type optical isolator, an input side lens (first lens) (5), a first birefringence unit (7), a Faraday rotator (9), a second birefringence unit (11) and an output side lens (second lens) (15) are arranged from the input side to the output side. The polarization dependent type optical isolator (1) is connected with optical fibers (3, 17) on the input and output sides, respectively, wherein a wedge angle (θ1) of the first birefringence unit (7) is different from a wedge angle (θ2) of the second birefringence unit (11).
Abstract:
According to one embodiment, a server device connected to a client device by way of a network includes a receiving unit, a first detecting unit, a cycle changing unit, a second detecting unit, and a transmitting unit. The receiving unit receives operation data through the network. The first detecting unit detects, from among operation events based on the received operation data, a specific operation event. The cycle changing unit, when the specific operation event is detected, changes a change detection cycle for screen data that is updated in an application in accordance with the specific operation event from a first cycle to a second cycle that is longer than the first cycle. The second detecting unit detects a change in the screen data in the second cycle. The transmitting unit transmits the screen data, in which the change is detected, to the client device.
Abstract:
A wireless communication apparatus wirelessly communicable with a plurality of communication devices including an identifier naming unit configured to give each of the plurality of communication devices at least one local identifiers allowed to be set optionally, a communication device management unit configured to associate the local identifier with a pre-assigned identifier to each of the plurality of communication devices, and to manage a relation between the plurality of communication devices with the local identifiers, and an identifier display control unit configured to control a display device to display the local identifier in place of the pre-assigned identifier as information specifying a currently wirelessly communicable communication device among the plurality of communication devices.
Abstract:
An image forming apparatus of the present invention includes a first circuit which creates image data on the basis of print job data, a second circuit which causes a printing unit to print an image on the basis of the image data created by the first circuit and is different from the first circuit, and a storage capable of being accessed by the first circuit and the second circuit, respectively. Additionally, when data is transferred in the first circuit and the second circuit, one circuit writes the data in the storage, and the other circuit reads out the data to transfer the data, thereby executing printing of an image.
Abstract:
An image forming system has a sheet deck assembly, an image forming apparatus, and a feeding buffering apparatus with plural feeding buffer trays for temporarily storing sheets of printing paper fed from plural printing paper decks of the sheet deck assembly. The feeding buffering apparatus feeds the temporarily stored sheets to the image forming apparatus.

Abstract:
According to one embodiment, an image relay apparatus includes a reception unit, a determination unit and a transmission unit. The reception unit receives compressed image data from a relay source apparatus. The determination unit determines whether or not the compressed image data is processable through a first path not involving decompression of the compressed image data, based on data on a relay destination apparatus. The transmission unit transfers, to the relay destination apparatus, either the compressed image data processed through the first path or recompressed image data obtained by processing the compressed image data through a second path involving decompression, drawing, and recompression of the compressed image data.
Abstract:
According to one embodiment, a server device includes a receiver, an acquisition unit, a difference extracting unit, an estimation unit, a determination unit, a compression unit, and a transmitter. The receiver receives manipulation information from a client device. The acquisition unit acquires a display image on which the manipulation information is reflected. The difference extracting unit extracts a region where pixel information on an image transmitted to the client device is not matched with pixel information on the display image. The estimation unit estimates an elapsed time since the manipulation information is received until the display image is acquired. The determination unit determines image quality, for which a response time is a predetermined value or less, on the basis of the elapsed time. The compression unit generates a compression image in which the image in the region is compressed with the determined image quality. The transmitter transmits the compression image.
