  • Publication number: 20230157038
    Abstract: An object of the present invention is to apply an organic thin-film transistor, which is produced using an organic semiconductor material, to an analog amplifier. The analog amplifier according to the present invention includes: a first amplifier (2) which voltage-amplifies an analog signal to be amplified; and a second amplifier (6) which power-amplifies the thus amplified signal output from the first amplifier to generate a drive signal that drives an equipment (10). The first amplifier includes an organic semiconductor amplifier element, namely an organic thin-film field-effect transistor (4), in which a semiconductor layer forming a channel is composed of an organic semiconductor. An organic semiconductor material is solvent-soluble and thus can be applied to form a film by a printing method such as an ink-jet method. Therefore, the production thereof can be carried out using a simple production facility.

  • Patent number: 8858829
    Abstract: The present invention intends to provide a novel cyclohexane compound that can form a liquid crystal composition of which response speed is improved when mixed with a nematic liquid crystal and the like and to provide a specified liquid crystal composition in which a novel cyclohexane compound is mixed. The novel cyclohexane compound is represented by the following formula (1). (In the formula (1), R1 and R2 represent the same or different R, ROCO or RCOO, and the R represents an alkyl group. The alkyl group may have an unsaturated bond, and, in the group, —CH2— may be substituted with —O—, —CO— or —COO—, and a part of or an entirety of hydrogen atoms may be substituted with a halogen atom or a cyano group. X and Y each independently represents a halogen atom or a hydrogen atom and does not simultaneously represent a hydrogen atom. Further, alternatively, X represents an oxygen atom and Y represents a direct bond to the oxygen atom.
