The server device includes a receiving unit, a first request unit, and a providing unit. The receiving unit receives an instruction from the terminal device to provide the information processing device with a predetermined service. The first request unit presents a test to the information processing device to authenticate whether or not the information processing device is being operated by a human. The providing unit provides the information processing device with the service in accordance with the instruction. The terminal device includes an instruction unit and a response unit. The instruction unit sends the instruction to the server device. The response unit makes a response to the test on behalf of the information processing device.
摘要:
A network management apparatus includes a processor, and a storage. The storage that stores an operation type indicating a rollback operation method by associating with attributes held by a command defining network settings. The processor executes extracting a difference between a command forming current setting information and a command forming previous setting information when the setting information set by the command is brought back to the previous setting information and acquiring the operation type corresponding to extracted command attributes from the storage unit, to generate a rollback command defining the rollback operation in accordance with the acquired operation type.
摘要:
An information signal to be fed to an information electrode group is formed of a selection pulse having a pulse width .DELTA.T, a first auxiliary pulse having a polarity opposite to that of the selection pulse and having the same width as that of the selection pulse before the selection pulse, a second auxiliary pulse having a polarity opposite to that of the selection pulse and having the pulse width of one third or less of the pulse width .DELTA.T after the selection pulse, and a third auxiliary pulse having the same polarity as that of the selection pulse and having the pulse width of one third or less of the pulse width .DELTA.T before the first auxiliary pulse. Thus, a driving margin is secured, and a flicker phenomenon is reduced.
摘要:
A display device is constituted by scanning lines arranged to form plural pixels including at least two types of pixels having mutually different areas inclusive of larger pixels and smaller pixels. The display device is driven by a driving method including a vertical scanning period wherein only scanning lines corresponding to the larger pixels are vertically scanned.

The waveforms of driving signals used for driving a display device which comprises a smectic liquid crystal and matrix electrodes including scanning electrode groups and information electrode groups are changed according to the ambient temperature in order to provide a satisfactory display in a wide range of temperatures. These types of the driving signals suppress unexpected inversion of the liquid crystal molecules at a low temperature and provide fast scanning at a high temperature.

摘要:
A liquid crystal display apparatus for presenting a high-quality image at a reduced power consumption comprises a liquid crystal display panel having scanning-signal electrodes and information-signal electrodes arranged in a matrix configuration, liquid crystals interposed between the scanning-signal electrodes and the information-signal electrodes, information electrode driving means for applying an information-signal voltage waveform to the information-signal electrodes, and scanning electrode driving means for applying a scanning-signal voltage waveform to the scanning-signal electrodes. The frequency of information-signal voltage waveform is lowered without changing the frame frequency of the apparatus by allowing two lines of scanning-signal electrodes to scan during a write pulse having a pulse length of .DELTA.T within one scanning period to select presentations of two pixels for each information-signal electrode.

A printing apparatus includes a first memory, a second memory, a first obtaining section, a second obtaining section, and a retrieving section. The first memory stores information concerning a registrant who has registered the printing apparatus as a print destination with a holding apparatus. The second memory stores information concerning an instructor who provides an instruction instructing the holding apparatus to hold print data that is to be used in printing performed by the printing apparatus. The first obtaining section obtains obtainment information. The second obtaining section obtains print-data identification information. The retrieving section retrieves, from the obtainment information, obtainment information which includes the print-data identification information and which is to be used to obtain print data that is held by the holding apparatus in accordance with the instruction and that is to be used in printing performed by the printing apparatus.
摘要:
A liquid discharging head cartridge that prevents a discharging head from being damaged due to exposure to liquid held in a liquid container during storage including the distribution period of a liquid discharging head cartridge, and ensures the reliability of the liquid discharging operation by the discharging head. An ink jet head cartridge includes an ink blocking member that is provided in the middle of an ink flow path and blocks ink supply to a recording head. The ink held in an ink container does not enter a section of the ink flow path between the ink blocking member and the recording head due to blockage by the ink blocking member.
