Abstract:
A panel driving method has, in one filed time period, an all-cell initializing subfield for causing initializing discharge in all discharge cells for displaying an image in the initializing period, and a selection initializing subfield for selectively causing initializing discharge in the discharge cell that has caused sustaining discharge in the last subfield in the initializing period. The number of all-cell initializing subfields can be increased and decreased, and the initializing voltage for causing initializing discharge in the all-cell initializing subfield can be varied. At least one of the number of all-cell initializing subfields and the initializing voltage of the all-cell initializing subfields in one field is controlled based on the accumulation of the panel power-on time.
Abstract:
Initialization waveforms with different voltages are applied respectively to a predetermined subfield with a small number of sustain pulses, and a subfield with the smallest number of sustain pulses in subfields other than the predetermined subfield. This offers a plasma display device that achieves a correct write operation in all discharge cells even if discharge interference occurs between adjacent cells, and also achieves a high contrast.
Abstract:
A recording medium processing apparatus is disclosed. The recording medium processing apparatus includes: a head unit which traces a track formed on a recording surface of a recording medium and reads a data signal; a signal processing unit which detects positional information of the recording medium on the basis of the data signal; and a printing unit which prints visible information on a non-recording surface of the recording medium by referring to the positional information.
Abstract:
In a driving method of a panel, one field period is formed by arranging a plurality of subfields that have an initializing period for causing initializing discharge in a discharge cell, an address period for selectively causing address discharge in the discharge cell, and a sustain period for causing as many sustain discharges as the number corresponding to luminance weight in the discharge cell. One field period is formed by arranging a plurality of subfield groups having a plurality of subfields whose luminance weights monotonically increase. A holding period when discharge is not caused is disposed before the head subfield belonging to at least one subfield group of the plurality of subfield groups. In the initializing period of the head subfield belonging to at least one subfield group, an initializing operation of causing initializing discharge is performed in the discharge cell where the sustain discharge has been performed in the sustain period of the immediately preceding subfield.
Abstract:
In the initializing period of each of sub-fields comprising one field, one of all-cell initializing operation and selective initializing operation is performed. The all-cell initializing operation causes initializing discharge in all the discharge cells for displaying an image. The selective initializing operation selectively causes initializing discharge only in the discharge cells subjected to sustaining discharge in the preceding sub-field. During initializing discharge using scan electrodes as anodes, and using sustain electrodes and data electrodes as cathodes in the all-cell initializing period, applying, to the data electrodes, a voltage for delaying discharge using the data electrodes as the cathodes, after discharge using the sustain electrodes as the cathodes.
Abstract:
An information recording and/or reproducing apparatus includes a laser light source from which a laser beam having a wavelength of from 220 nm to 280 nm exits; and a converging lens unit disposed at a nearfield area of a recording medium and upon which the laser beam from the laser light source is incident. The converging lens unit includes an objective lens and a solid immersion lens. The solid immersion lens is disposed between the objective lens and the recording medium, and is formed of a highly refractive material having a high transmittance. The information recording and/or reproducing apparatus records an information signal onto or reproduces an information signal from the recording medium by irradiating the recording medium with the laser beam from the laser light source.

Abstract:
An electron beam irradiation system has a pumping block at an end of a microscope column of electron optics. The system has the rotary stage, the microscope column for directing an electron beam at the target on the rotary stage, the pumping block for evacuating air in the gap between the column and the target, a moving mechanism for sliding the rotary stage between a working position and a mounting position, and a cover member. In the working position, the target is opposite to the column. The cover member is brought into intimate contact with the rotary stage or target to prevent vacuum deterioration when the rotary stage moves from the working position to the mounting position.
