Abstract: PURPOSE:To get an element which is simple and good in preservation stability by making acridine, pyrene and anthracene coloring matter compounds to be contained in a polypeptide derivative at specified percentages by weight. CONSTITUTION:Polypeptide derivative is made to contain pyrene, anthracene and acridine coloring matter compounds at percentages by weight at a rate of 1 - 500 - 1/5, and then, a prescribed amount thereof is desolved in an organic solvent to make uniform film on an element substrate 1 by use of the solution of the organic solvent and form a polymer layer 5. Then, a heating layer 2 is installed above and below the layer 5 or above or below it, and further, electrode layers 3a, 3b and total reflection layers 4a, 4b are installed between the heating layers 2. If the polypeptide derivative is heated over the threshold level without applying voltage thereto, a cholesteric liquid crystal layer is manifested to transmit clockwise or counterclockwise circularly polarized light. A cholesteric phase is changed into a nematic phase by then applying voltage to the polypeptide derivative, so that both the clockwise and counterclockwise circularly polarized lights are absorbed to make IN-OFF control of transmission. Moreover, the speed of response at the time of application of voltage is increased by introducing mesogen element to the side chain and the speed of the optical element can be further increased.

IPC: B41F17/36
Filed: 1991-11-15
Abstract: PURPOSE:To simplify manufacturing process of a resistor by simultaneously printing an indication part with the same material as that of a protective film on the section of a board surface where no resistance film is formed when printing the protective film on a resistance film. CONSTITUTION:An insulating material such as glaze, etc., is screen-printed on plural resistance films 5 for forming a protective film 6. The protective film 6 is printed only on the section where a resistance body 5 is present, and a base plate surface 2 is exposed where a resistance film 5 is not present. When the protective film 6 is printed, a display part 7 ('103' in this example) is simultaneously printed with the same insulating material as the protective film 6 on the board surface 2 where no resistance film 5 is present. The protective film 6 and the display part 7 are baked after dried out as required. As a result, both a process different from a protective film forming process and a material different from a protective film are not required, a manufacturing process for a resistor, thus, can be simplified.
