  • Patent number: 8420860
    Abstract: The present invention provides a triarylmethane compound and a color filter containing the compound in a blue pixel portion, the triarylmethane compound being capable of providing a colored material which causes little change in hue over a long period of time even under high temperature or light irradiation. For example, when used for preparing a blue pixel portion of a color filter, the triarylmethane compound is capable of providing a liquid crystal display device or the like which can provide a high-brightness liquid crystal display having excellent brightness over a long period of time even under high temperature or light irradiation. The triarylmethane compound contains, as a counter anion for a basic triarylmethane dye cation, a heteropolyoxometalate anion represented by (P2MoyW18-yO62)6?/6 wherein y=an integer of 1, 2, or 3, and the color filter contains the triarylmethane compound in a blue pixel portion.

  • Patent number: 8068297
    Abstract: The present invention relates to a pigment composition or pigment dispersion that is ideal for producing the blue pixel portion of a color filter for a liquid crystal display device, and a color filter. The invention has an object of providing a color filter having a blue pixel portion that yields a liquid crystal display device having a high degree of contrast that enables the display screen to be viewed with improved clarity, and a high level of brightness that produces a brighter display screen, as well as providing a pigment composition or dispersion that can be used to produce the color filter. The above object can be realized by using a dioxazine derivative that is substituted with a sulfamoyl group having a specific polyalkylene oxide group, and a pigment composition or dispersion for a color filter that includes this dioxazine derivative and a blue organic pigment or violet organic pigment.

  • Patent number: 6577940
    Abstract: A shift control apparatus comprises clutches driven by shift solenoids and whether or not the raising of the rotation speed occurs in an internal combustion engine is determined. If the raising of the engine rotation speed is detected, a hydraulic pressure learn correction is made to engagement hydraulic pressure and a time learn correction is made to the hydraulic pressure supply preparation time. The correction ratio of the energization-hydraulic pressure characteristic (I-P characteristic) of clutch clearance and the shift solenoid is set so as to become an appropriate distribution ratio and the learning is started based thereon.

  • Patent number: 6491605
    Abstract: When a contradictory event in which raising of the engine rotation speed is detected and the inertia phase start time is early occurs (8), a learn correction is made to engagement hydraulic pressure (ON side). If the raising of the engine rotation speed cannot be canceled still after the learn correction is made, release hydraulic pressure (OFF side) is increased for correction.

  • Patent number: 5684708
    Abstract: A numerically controlled machining method and a numerically controlled machining system execute numerically controlled machining. An optimum processing tool is selected based on the numerical control orders, and the processing steps are optimized. A numerically controlled machining system is constituted by a numerically controlled processor, controllers and numerically controlled machines. The numerically controlled processor finds production times for machining parts for all the numerical control orders and compares them with a reference value to classify them into a group of special express processes and a group of normal processes. The special express processes pertain to the group of machining methods giving importance to the degree of finish, and the normal processes are divided into a group of machining methods for minimizing the exchange of machining tools or to a group of machining methods of optimizing a drawing number, whichever gives better machining efficiency.

  • Patent number: 5683889
    Abstract: The present invention relates to a reagent for measurement of magnesium ions utilizing a complex of magnesium ion with adenosine 5'-triphosphate as a substrate of glucokinase derived from bacteria of the genus Zymomonas. By using this reagent, enough measuring range to measure a magnesium ion in various samples such as biological fluids, foodstuffs, etc. can be accomplished and, at the same time, the measurement can be made with high precision and reliability even in a sample containing a magnesium ion in low concentration. Further, the reagent of the present invention is superior in operation property by reducing a dilution operation, and has sufficient performance for a routine method for determination of magnesium ions.

  • Patent number: 5196955
    Abstract: An improved liquid crystal optical device utilizing a ferroelectric liquid crystal and a driving method for the same are described. A ferroelectric liquid crystal material disposed between a pair of substrates in the optical device has a coefficient of viscosity of 5000 cps to 30000 cps and a negative dielectric anisotropy at operational temperatures, e.g. between 10.degree. C. and 40.degree. C. The liquid crystal consists of a number of layers normal to the substrates. The constituent layer in turn consists of liquid crystal molecules parallel to the substrates. Misalignment of the molecules yields bends in the layered structure which degrades the contrast ratio. When given alternating electric fields, the molecules are subjected to an electric torque which exerts thereon in order to force the molecules parallel to the substrate by virtue of the negative dielectric anisotropy so that the bends can be removed.

  • Patent number: 5109295
    Abstract: A new type of non-volatile bistable liquid crystal device is disclosed. The device has substrates spaced apart by such a distance that the molecular arrangement of the liquid crystal moaterial is helical and is arranged such that the liquid crystal molecules can selectively take up either of two optically anisotropic stable conditions in dependence puon an applied electric field. The transition between the two stable conditions takes place via an intermediate conditon in which the liquid crystal molecules are reearranged in helical form and represent an optically isotropic condition.

  • Patent number: 5001409
    Abstract: In an apparatus for measuring texture and characterization of the surface of a sample on the basis of the drive signal of a servo control circuit by allowing a probe-tip (1) to approach the sample (2) and subjecting the probe-tip (1) to servo control so that a current, which is generated by moving the probe-tip (1) on the sample surface and which flows between the probe-tip (1) and the sample (2), becomes constant, the present invention discloses a surface metrological apparatus comprising a circuit (11, 12) for correcting the texture and characterization of the sample by use of a current error of the measured value of the current described above from the set current value.
