Abstract: A viewing angle control element of the present invention contains transparent regions 23 having a transmittance T1 and light shield regions 24 capable of switching between a transmittance T2 and a transmittance T3 which is less than T1 and T2 according to an external signal. Each of the transparent regions 23 and the light shield regions 24 is positioned opposite to one of pixels. Displays are produced at or close to the original brightness of the image display element in wide viewing angle mode, whereas in narrow viewing angle mode, light transmission is limited to achieve narrow viewing angles. This is in contrast with other viewing angle control elements which produce displays at or close to the original brightness of the image display element in narrow viewing angle mode, whereas in wide viewing angle mode, light is diffused or otherwise modified to achieve wide viewing angles.

The first optical-path changing layer has a refractive index substantially equal to that of the transparent substrate, and includes predetermined protrusions and predetermined depressions. Further, a low refractive-index layer is provided on a front-face side of the first optical-path changing layer. The low refractive-index layer is in contact with the protrusions and the depressions of the first optical-path changing layer, and has a smaller refractive index than the refractive index of the first optical-path changing layer. Further, a second optical-path changing layer is provided on a rear-face side of the rear-face side transparent substrate. The second optical-path changing layer includes predetermined protrusions and predetermined depressions.

Abstract: A weather prediction unit calculates a local numerical weather prediction model from GPV data and weather observation data and predicts a regional meteorological phenomenon in a fractionated region. A power demand prediction unit predicts a power demand in each region on the basis of the regional prediction result of the meteorological phenomenon. A generated heat value prediction unit predicts a generated heat value in each region on the basis of the regional prediction result of the power demand. The regional prediction result of the generated heat value is reflected on the numerical weather prediction model. Meteorological phenomena are predicted by adding the thermal energy as sensible heat from the earth's surface and taking artificial exhaust heat by electrical energy into consideration. Accordingly, weather prediction and power demand prediction are organically combined so that accurate weather prediction and power demand prediction are implemented while considering artificial heat exhaust.

Abstract: A sintered metal sprocket for a silent chain is produced by the following steps. A base mixture is prepared, which contains a powder metallurgical iron powder, a lubricant and a graphite powder. Then, the base mixture is subjected to a compression molding while being heated at above approximately 100° C. thereby to produce a green compact. Then, the green compact is subjected to a sintering at a temperature above approximately 1180° C. For much improving the mechanical performance of the sprocket thus sintered, the same may be subjected to a carbonizing hardening or an induction hardening.

Abstract: An antenna section radiates a pulse beam and receives its reflected wave, and a signal processing section observes a rain or cloud occurring region within a covered area based on a signal intensity of the reflected wave. In this case, to obtain wind direction and velocity information for the rain or cloud occurring region, the signal processing section observes Rayleigh scattering-induced Doppler echo components in that region to calculate the wind direction and velocity from a result of the observation. To obtain the wind direction and velocity information for a region other than the rain or cloud occurring area, the beam formed by the antenna section is directed toward the region to be observed so that the signal processing section can observe Bragg scattering-induced echo components based on a received signal of the reflected wave to calculate the wind direction and velocity from a result of the observation.

Abstract: The invention relates to a liquid crystal display device wherein phase difference plates equal in retardation value, being composed of uniaxial polymer film or the like, are disposed symmetrically at the front side and back side of an STN liquid crystal panel, and the wavelength dispersion is made nearly ideal. As a result, the phase difference is compensated over the entire wavelength region, and the azimuth angles of the exit ellipsoidal polarization are aligned. Thus, a colorless display and a high contrast may be realized at the same time.
