  • Patent number: 11624970
    Abstract: A projection liquid crystal display device including a first optical system that splits a light beam outputted from a light source into a red light beam, a green light beam, and a blue light beam, a red liquid crystal panel, a green liquid crystal panel, and a blue liquid crystal panel that modulate the red light beam, the green light beam, and the blue light beam, respectively, a second optical system that combines the modulated red light beam, the modulated green light beam, and the modulated blue light beam into one optical path, and a projection lens system that projects a light beam outputted from the second optical system on a projection surface, in which a configuration of a liquid crystal layer of the red liquid crystal panel is different from respective configurations of liquid crystal layers of the green liquid crystal panel and the blue liquid crystal panel.

  • Publication number: 20220390783
    Abstract: It is an object of the present disclosure to dispose an optical element on a lower surface side of transistors without being influenced by heat treatment in a transistor forming process such that peeling, displacement, and the like do not easily occur. A transistor array substrate includes: a first substrate (110) including transistors (113) arranged in an array; and a second substrate (120) including an optical element (122), in which the transistors are arranged on a front surface side of the first substrate, and the second substrate is bonded to a back surface of the first substrate by plasma bonding treatment.

  • Publication number: 20220113611
    Abstract: A projection liquid crystal display device (1) including: a first optical system that splits a light beam outputted from a light source (40) into a red light beam, a green light beam, and a blue light beam; a red liquid crystal panel (100R), a green liquid crystal panel (100G), and a blue liquid crystal panel (100B) that modulate the red light beam, the green light beam, and the blue light beam, respectively; a second optical system that combines the modulated red light beam, the modulated green light beam, and the modulated blue light beam into one optical path; and a projection lens system that projects a light beam outputted from the second optical system on a projection surface (30), in which respective driving voltages of the red liquid crystal panel (100R), the green liquid crystal panel (100G), and blue liquid crystal panel (100B) are identical to each other, and a configuration of a liquid crystal layer (110) of the red liquid crystal panel (100R) is different from respective configurations of liquid

  • Patent number: 6685995
    Abstract: Liquid crystalline compounds suitable for driving at a low voltage and at a wide temperature range, and suitable for high speed response, liquid crystal compositions comprising the compound, and liquid crystal display devices comprising the liquid crystal composition. The crystalline compounds are ester compounds expressed by the general formula (1) wherein R1 represents e.g. a hydrogen atom; A1 to A5 each independently represent e.g. 1,4-cyclohexylene, 1,4-phenylene, 1-cyclohexene-1,4-diyl, 3-cyclohexene-1,4-diyl, 1-sila-1,4-cyclohexylene, or 4-sila-1,4-cyclohexylene; bonding groups Za to Zd each independently represent e.g. a single bond, —CH2—, —O—, —C≡C—, or an alkylene group or alkenylene group having 2 to 4 carbon; bonding group Ze represents e.g.

  • Patent number: 4890719
    Abstract: An excavator for a bucket elevator type continuous unloader has a horizontal travel section constituting an excavating section of the bucket elevator which is constituted by an endless bucket chain, and a parallel link mechanism. The parallel link mechanism is positioned below an elevator post which is moved up and down by a boom, and supports the horizontal travel section. The excavating section is moved sideways from just below the elevator post by swinging the parallel link mechanism so as to rake up bulk cargo such as ore and coal located deep inside the hold. The degree of movement of the excavation section in the vertical direction is detected by detecting the swing angle of the parallel link mechanism, by which the boom is automatically controlled so as to maintain the excavating section at the same level. In this way, fumbling of the excavated bulk cargo can be prevented.
