There is provided a fluorine-containing diamine represented by formula (1). In this formula, R1 represents a condensed polycyclic type aromatic hydrocarbon group, and at least one —C(CF3)2OH group and at least one —NH2 group are in a relation such that they are attached to adjacent carbons of carbon atoms constituting the condensed polycyclic type aromatic hydrocarbon group. Polymer compounds derived from this fluorine-containing diamine have superior low dielectric property and low water-absorbing property, and, in addition to that, shows low thermal expansion property and high glass transition temperature.
摘要:
Disclosed is a fluorine-containing dicarboxylic acid represented by formula (1), wherein n represents an integer of 1-4, and the two carboxylic groups are not adjacent to each other on the aromatic ring. It is possible to obtain a linear polymer compound by reacting the fluorine-containing dicarboxylic acid with a comonomer (e.g., diaminodiol). By thermal cyclization, this linear polymer compound can be converted into another polymer compound having superior characteristics.
摘要:
When a first-stage operation or first operation of a freeze switch is performed, a still image is stored in image memory and is displayed on a monitor. When an electronic variable power switch is operated in this state, a still image electronically enlarged is formed on the basis of a signal of the above-described image memory. Then, when a second-stage operation or second operation of the freeze switch is performed, the above-described enlarged still image is recorded in a recording device. Owing to this, it is possible to display and record an arbitrary still image that is enlarged and is positioned on optimum conditions. Moreover, by single operation of an electronic variable power switch, an enlarged still image can be formed and can be also recorded simultaneously. Furthermore, even if continuous recording operation is prohibited, the next recording operation can be performed by operating the electronic variable power switch.
摘要:
A resist composition comprising a blend of a cyclic polymer having alcoholic groups as soluble groups and a polymer having carboxyl or hexafluoroalcohol groups whose hydrogen atoms are replaced by acid labile groups as a base resin forms a resist film which is improved in transparency, alkali dissolution contrast and plasma etching resistance.
摘要:
A movable lens is provided at the tip of an electroscope, and an optically enlarged image can be observed by moving the movable lens by a motor. A microcomputer measures the entire moving time from a far end to a near end of the movable lens, and the moving time is used as the variable power position information about the movable lens. The variable power position information is displayed by a meter display, etc. on a monitor. Thus, an encoder, etc. is not required.
