Analysis of ozone generation from air in silent discharge

Abstract: A new theoretical model for ozone generation from air is proposed. This model considers the dependency of the ozone dissociation rate by electron impact on the electric field strength, in addition to ozone decomposition processes through the reactions with nitrogen oxides. Assuming a stationary and uniform discharge in time and space, ozone concentrations obtained experimentally under various discharge gap widths and gas pressures are in good agreement with the analytical results. It is concluded that the discharge condition of a narrow gap and accordingly an optimized high gas pressure is one of the most effective means of efficient ozone generation for an air-fed ozone generator.

Resonant frequency and radiation efficiency of meander line antennas

Abstract: One of the approaches to reducing the size of half-wavelength linear dipole antennas is the meander dipole antenna, where the elements form a meander line. This paper presents a formula for the relationship between the geometrical size and the resonant frequency of the meander line dipole antenna, and a calculation formula for the radiative efficiency is derived from the result. It is shown that the geometrical parameters of the meander line dipole antenna can be determined from the specified radiative efficiency. © 1999 Scripta Technica, Electron Comm Jpn Pt 2, 83(1): 52–58, 2000

Planar light source device

Abstract: A planar light source device includes: a plurality of point light sources, each of which emits a light; a light guide plate that includes a first surface, and a second surface perpendicular to the first surface, and that is configured to guide the emitted lights incident from the first surface to be emitted from the second surface; a bottom case including a side portion substantially parallel to the first surface; a light source substrate that includes the plurality of point light sources arranged thereon at a predetermined interval, and that is arranged at a side of the first surface; a frame that sandwiches the light source substrate and the side portion of the bottom case and holds the second surface and that includes a plurality of gaps at positions facing the point light source.
