Title: Polymer dispersion type liquid crystal device
Inventor: TAKAGI SHINYA
IPC: C08K5/315
Filed: 2000-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction of contrast ratio. SOLUTION: A liquid crystal-polymer composite layer 2 is disposed between a pair of substrates 1a and 1b and the composite layer 2 is constituted of a polymer layer 20, a two-frequency driving liquid crystal dispersed in the polymer layer 20 and particulates 21 dispersed in the polymer layer 20. The particulates 21 having a specific functional group on their surfaces are used. The scattering effect of light can be enhanced, since the particulates 21 are mixed in the composite layer 2. The reduction of the light transmission condition can be suppressed, since the particulates 21 has the specific functional group on their surfaces. Thus, a high contrast ratio can be obtained, since the scattering effect of light can be enhanced and the reduction of the light transmission condition can be suppressed just after the application of voltage is suspended.

Title: Semiconductor photoelectric cathode
Inventor: ARAGAKI MINORU
IPC: H01J29/38
Filed: 2000-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor photoelectric cathode that is capable of improving its property. SOLUTION: When the light absorption layer 2 is thick, deterioration phenomenon in the time resolution appears, but when the thickness of the light resolution layer 2 is limited, those lower part of electric concentration in one electron group is cut out. Therefore the overlapping region of the neighboring electron concentration distribution is reduced, and by a shortened running time necessary for the passing of the electrons, the overlapping region by diffusion can also be limited, and further, the electric field intensity can be increased. With these synergistic actions, the time resolution of infrared rays can be drastically improved.  In cases where the time resolution is 40 ps at the thickness of the light absorption layer being around the wavelength of the infrared rays, 1.3 μm, the time resolution will become 7.5 ps when the thickness of the light absorption layer is made 0.19 μm.
