Title: Liquid crystal display
Inventor: KIISU HAAROO NIKORASU
IPC: G02F1/1335
Filed: 1990-08-13
Abstract: PURPOSE: To reduce the influence of unwanted light upon a thin film transistor(TFT) by making the thickness of one layer of the TFT different for each group at least and selecting this thickness according to color light. CONSTITUTION: The display elements of different colors form three groups, namely, the groups of a red, green and blue operating display elements. For example, a TFT 16 related to the group of the red display element has the thickness of a gate insulated layer for selecting the quantity of light, which is absorbed by its semiconductor layer 32, so as to get closer to a minimum value. Besides, the group of TFT 16 related to the green and blue display elements respectively has the thickness, which is different from that thickness, of the gate insulated layer selected so that the quantity of light absorbed in the relational semiconductor layer can similarly get closer to the minimum value each other.  Thus, when irradiating a display device with light directed from the side of liquid crystal away from the TFT 16, the quantity of light absorbed by the semiconductor layer 32 corresponding to a certain wavelength or wavelength range can be made closer to the minimum value.

Abstract: PURPOSE:To prevent a fish pass or a branched channel from wearing or breaking by gravel flowing-in through a watercourse, by a method wherein the bed of a waterway is divided into two parts and a coefficient of roughness of the surface of the bed for one of them is made smaller than that of the bed for the other. CONSTITUTION:A watercourse 1 is formed at the top of a structure such as a dam body. The bed of a waterway ranging from an intake to a partition wall 3 is divided into two parts in the direction of water-flow and waterway beds 6, 7 are formed. The waterway bed 6 is laid down with materials 8 having low roughness so as to become progressively narrow ranging from the vicinity of the corner end part of the intake at the side of the waterway bed 7 to the partition wall 3. On the other hand, the waterway bed 7 remains placed concrete, in order that a coefficient of roughness of the waterway bed 7 is made larger than that of the waterway bed 6. In another case, the roughness of the waterway bed 7 is controlled by putting cobblestones therein. Gravel falling together with the water-flow collects on the water bed 6 with the coefficient of roughness smaller, using the difference between the coefficients of the roughness. In this way, a watercourse 5 can be prevented from wearing.
