The row electrodes and said column electrodes being provided between the front substrate and the back substrate and forming unit light emission areas at intersections with each other within the discharge space. A crystal having a volumetric particle-size distribution in which a ratio of a crystal having a particle size of 0.7 μm or less is 25% or less, is provided in an area facing the discharge space between the front substrate and the back substrate.
Abstract:
A plasma display panel and a drive method therefor, which can enhance a representation capability when displaying a dark image. The plasma display panel includes fluorophor layers containing magnesium oxide. The drive method includes a reset step to initialize all the pixel cells into states of one of a light-up mode and a light-off mode, and an address step in which the pixel cells are caused to perform address discharges selectively in accordance with pixel data, which are successively executed in each of a head subfield and a second subfield within a one-field display period. In reset step, a voltage that sets row electrodes on one side, in the row electrode pairs as an anode and sets the column electrodes set as a cathode is applied between the row electrodes on the one side and the column electrodes.
Abstract:
A housing for a portable electronic device includes a metallic base, a chemical plating layer, a prime layer, a color coating layer, a decorative layer, and a transparent protection layer. The chemical plating layer, the prime layer, the color coating layer, the decorative layer, and the transparent protection layer are coated on the metallic base in that order. The decorative layer defines a pattern extending through the decorative layer.
Abstract:
A received signal delivered through a transmission line can be compensated for CFO and DCO to improve the SNR of the received signal, eventually resulting in an effective improvement in the error rate. In this context, methods for estimating and compensating for CFO and DCO have been studied, for example, using pilot signals or a blind method. However, the methods would require a huge amount of calculations for the estimation of CFO in the presence of DCO, as with the ML method, or never essentially eliminate errors from an estimated value. The received signal has convoluted influences through the transmission line, so that observation of the continual symbols of periodic pilot signals on the frequency axis shows just a phase shift by the CFO. Therefore, the CFO can be analytically found from the continual symbols of periodic pilot signals, thereby allowing the DCO to be estimated and both the CFO and the DCO to be compensated for.
Abstract:
A ring mechanism having a housing and at least one ring configurable between a closed position for retaining loose-leaf pages and an open position. A pair of hinge plates, operatively connected to the ring, are pivotable within the housing between first and second position corresponding respectively to the closed and open positions of the ring. Each hinge plate has a free end and a line of weakness formed therein proximate the free end to facilitate bending of the hinge plate. A hinge plate actuator has a bearing surface engageable with the hinge plates proximate the free ends thereof upon movement of the actuator from a first position toward a second position thereof such that the hinge plates bend proximate their free ends to delay pivoting movement of the hinge plates upon initial movement of the actuator from its first position toward its second position.

Abstract:
An exo-tetrahydrodicyclopentadiene is produced from endo-tetrahydrodicyclopentadiene through isomerization reaction. An acidic ionic liquid is used in the isomerization. The isomerization of endo-tetrahydrodicyclopentadiene gives a reaction conversion and a selectivity both higher than 99%. Besides, the ionic liquid used is environmental-friendly and recyclable.
