Title: Thin-film transistor
Inventor: HIRANAKA KOICHI
IPC: H01L27/12
Filed: 1986-06-18
Abstract: PURPOSE:To prevent a current from being unnecessarily outputted in response to stray light by a method wherein an amorphous semiconductor film, which is a two-film layer of amorphous silicon hydride and amorphous silicon carbide, is employed in a thin-film transistor. CONSTITUTION:A thin-film transistor activation layer is constituted of a two- film layer of an amorphous silicon hydride thin film 4a and amorphous silicon carbide thin film 4b. In such a design, the effective optical gap falls at the middle between the large optical gap of amorphous silicon carbide and the small optical gap of amorphous silicon hydride. Exposure to stray light triggers off but a very little photoelectric current, which reduces the possibility of a current being outputted in response to such light and protects the S/N ratio from lowering. Accordingly, when a thin film transistor of this design is employed to drive a liquid crystal display unit capable of tonal display, the tone is protected from undesired changes attributable to stray light and therefore the tonal display characteristic of the unit is improved.

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To improve brightness of a blue light emitting phosphor on a color image screen to fully exhibit the brightness of a red and green light emitting phosphor, and brighten the whole color image by setting an inter-barrier rib distance where an R phosphor layer is formed smaller than an inter-barrier rib distance where a B phosphor layer is formed. SOLUTION: An inter-barrier rib distance Pr of a cell where a red phosphor layer is formed is set smaller than an inter-barrier rib distance Pb of a cell where a blue phosphor layer is formed, and a luminance level as a whole is enhanced, and a color image is brightened further. Since Pb is set larger than an inter-barrier rib distance Pg of a cell where a green phosphor layer is formed, a luminance level of the whole can be enhanced further. Since these are set in the relationship of (1<Pb/Pr<=2), a problem such as blue light emitting luminance is low and a problem such as red luminance is high and a color temperature easily lowers, can be simultaneously solved, and a beautiful white color can be realized on an image screen.

Title: Snow-melting system for cooling tower
Inventor: OTSUKA HIROSHI
IPC: F28F27/00
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent snow accumulation on a fan or in a cooling tower when the fan is stopped by providing a sprinkler above the fan and sprinkling water over the fan at the time of stopping the fan. SOLUTION: Firstly, the freezing of cooling water is prevented by making the water to flow a little by fully opening a valve 15 and slightly opening valves 16 and 17. Air is sucked in a cooling tower 1 through a vent hole by rotating a fan 7 and discharged from the top of the tower 1 through a filler material 4. At the same time, water is sprinkled over the filler material 4 from a main distributor 5 by operating a pump 9. When the sprinkled cooling water drops onto the material 4, the water is cooled by blown-up air, collected in a water storage tank 8, and sent to a heat exchanger 10 by the pump 9. Then the water is heated through the heat exchange with water to be cooled and again sprinkled from the distributor 5. Therefore, snowing on the fan 7 or in devices incorporated in the cooling tower 1 can be prevented.  Since the sprinkler used for sprinkling the cooling water is enabled to supply the cooling water to a sprinkler provided on the cooling tower 1, a snow-melting system becomes simpler.
