摘要： There are provided an optical disk and a manufacturing method thereof which can increase its recording capacity, e.g. to 15 GB or higher. This optical disk may comprises an optical disk substrate 3 in which successive pits corresponding to a recording signal are formed, a reflection film 4 formed in this optical disk substrate 3 on its surface that successive pits 2 are formed and a light transmissive layer 5 formed on this reflection film 4. When a recorded signal is read out, i.e. reproduced from the optical disk, a signal recorded as successive pits is read out by irradiating of short-wavelength laser light having a wavelength of 350 nm to 420 nm from the side of the light transmissive layer 5 formed on the surface of the optical disk. Moreover, in this optical disk, when the successive pits are observed from the side of the light transmissive layer irradiated by reproducing laser light, the successive pits contain pits having length and width ranging from 80 nm to 250 nm, and the reflection film has the film thickness selected to be 20 nm or less, e.g. greater than 8 nm.

摘要： To provide a PDP display device and a drive method which use a set-up pulse having a portion that drops in voltage at a rate of 2V/&mgr;sec or more, whereby the occurrence of discharge errors in a sustain period can be suppressed even when wall charges are not sufficiently erased in an erase period and excess wall charges remain on some or all electrodes in a set-up period. To this end, the drop portion of the set-up pulse applied to a scan electrode group is set after a pulse applied to a sustain electrode reaches a voltage which does not cause a discharge between the sustain and scan electrodes. As a result, the occurrence of discharge errors in the sustain period is suppressed, without prolonging the set-up period.

摘要： An improved delta sigma digital-to-analog converter in which the thermometer code, which is output from a thermometer code converter, is divided into P blocks for every Q bits. An arrangement of the blocks is shifted in rotation by a barrel shifter at a frequency fs. Along with this, an arrangement of bits within each block is shifted in rotation by a shift register at a frequency of Q times fs. The bits within the code thus obtained are provided to local DACs, each specified to correspond to each of the given bits. In this manner, it is possible to maintain a lower operating frequency while at the same time to reducing the distortion in the output caused by a change in shifting the data in rotation in the local DACs, which change occurs depending on bit levels of the data in a form of the thermometer code.

摘要： A photoresist is applied onto a substrate, the photoresist-coated substrate is exposed to a laser beam of 300 nm or less in wavelength to form a latent image indicative of an information signal, and the photoresist on the substrate is developed to form a pit/groove pattern indicating the information signal. The photoresist has a mean value of 0.1 or less between extinction coefficients before and after the exposure to the laser beam.
