Abstract: In a plasma display panel, data electrodes are formed parallel to each other on a first substrate, and a selection voltage is to be applied to them. A dielectric layer covers a surface of the first substrate to include the data electrodes. Linear partitions are formed at a predetermined interval on the first substrate to be parallel to the data electrodes. A second substrate opposes the first substrate. A closed space between the first and second substrates is filled with a gas. A pair of sustain discharge electrodes are formed on the second substrate to intersect the data electrodes, and a discharge voltage is to be applied across them. Intersections of the pair of sustain discharge electrodes and data electrodes form matrix-like discharge cells. Stepped partitions are formed at a predetermined interval on the first substrate in a direction intersecting the linear partitions, and have heights smaller than those of the linear partitions.

Abstract: While transmitting an electromagnetic wave from a transmitting antenna to, for example, a magnetostrictive resonator, buried in a road, a reception section composed of a reception amplifier and signal processor is inactivated. After stopping transmission of the electromagnetic wave, the reception section is activated and a receiving antenna detects an electromagnetic wave radiated by the magnetostrictive resonator. In this method, a magnetostrictive resonator detection apparatus having a sufficient directivity and detection distance can be presented. The magnetostrictive resonator detection apparatus applying this detecting method is mounted aboard a vehicle, and a plurality of magnetostrictive resonators are buried in the road. By sequentially transmitting and receiving electromagnetic waves at different resonance frequencies thereof, and judging the configuration of the road and the vehicle, a safe traffic system is presented.

The light sources are located inside a boundary line of a mirror reflection area and the light reflector is located outside the boundary line of the mirror reflection area so that mirror reflection does not occur with the bar code reader.

Abstract: In a gas discharge display element according to the present invention, two pairs of electrodes are arranged in a discharge space of a display cell and one of the electrode pairs which forms a first discharge space between the first electrodes is driven such that discharge having a memory function and capable of being memory-driven is produced during a time in which light emission of the display cell is sustained. The other electrode pair is driven with a voltage pulse having duration smaller than that of the driving voltage pulse for the first electrode pair such that discharge a is obtained in the other space defined between the electrodes of the other electrode pair using the discharge in the first space as a seed discharge. The duration of the drive pulse for the second electrode pair preferably terminates before the discharge current is reduced due to the formation of a wall charge.
