    摘要: It is an object of the invention to improve the viewing angle properties of a liquid crystal display device by controlling the state of orientation of liquid crystal molecules. The liquid crystal display device is constructed with an liquid crystal display element disposed between a pair of polarizing plates, and with phase difference plates disposed between each polarizing plate and the liquid crystal display element. The phase difference plates are selected so that nx.gtoreq.nz>ny is satisfied and the Nz value is in the range of 0.ltoreq.Nz.ltoreq.0.5. The liquid crystal display element is constructed by placing a liquid crystal layer between substrate members prepared by forming transparent electrodes and orientation films in the pair of light transmitting plates, and the liquid crystal layer sandwiched between the transparent electrodes is used as picture elements. One picture element contains mixed liquid crystal molecules with different pretilt angles controlled by a light irradiation step after application and baking of the film material for the orientation films As a result, it is possible to obtain excellent display quality in both of the opposing viewing angle directions.

    摘要: A liquid crystal display device of stable color tone uses phase difference plates made of a uniaxially stretched polymer film and comprises a polarizer plate, a first phase difference plate, a second phase difference plate, a supertwisted nematic type liquid crystal display panel, and a polarizer plate which are stacked on each other in this order. The rate of retardation change with the change in viewing angle of the uniaxially stretched polymer film is denoted coefficient K defined by three-dimensional refractive indexes, coefficient K1 of one of the phase difference plates is set in a range of -1.ltoreq.K1.ltoreq.0.17 and coefficient K2 of the other phase difference plate is set in a range of 0.ltoreq.K2.ltoreq.1.

    摘要: A flow control having a wide flow rate range and excellent linearity between the degree of valve opening and flow rate. The valve includes a cylindrical or conical valve head formed on a circular-truncated-cone-shaped working face which is tapered towards the outlet of the valve with the valve head being located inside the outlet-side casing. With respect to the area of the valve opening defined by the valve head and the valve seat, the valve head is shaped so that the rate of change of the flow rate with valve stroke is small and linear, whereby fine control of the flow rate can be accurately achieved over the entire flow rate range. The valve stroke to fully open the valve occurs in the inlet-side casing. A servo motor or the like is employed as the drive source for operating the valve.

    摘要: A method of assembling a wheel tire to a tire rim as a tire wheel is disclosed. The method comprises steps of measuring dynamic balances of a rim and a tire wheel formed by securing a tire to the rim, seeking static balances of the rim and the tire from these dynamic balances, and securing the tire to the rim by directing the direction of the static balance of the tire at 180.degree. opposite to the direction of the static balance of the rim.
