    Abstract: A vehicle motion control system is provided. In a first state requiring understeer suppressing control, a controller determines, based on a yaw rate deviation, a first control amount of an actuator selected so as to generate an inward turning moment a vehicle. In a second state requiring spin suppressing control, the controller determines, based on the sideways slip angular velocity, a second control amount of an actuator selected so as to generate an outward turning moment in the vehicle. When the first and second states are concurrent, the controller selects an actuator to be controlled by the larger of the absolute values of first and second cooperative control amounts, and determines a control amount of the selected actuator as the sum of the first and second cooperative control amounts. Accordingly, the understeer suppressing control and the spin suppressing control can be performed in parallel, improving control performance.

    Abstract: The object of the present invention is to provide an antenna for communicating with a low earth orbit (LEO) satellite which is small-sized and light and can track a LEO satellite at high speed at a small-sized earth station using a LEO satellite. The antenna according to the present invention uses two offset parabolic antenna-type reflectors and each primary feed is installed in the focal position of a paraboloid forming the reflector. The quantity of an offset of the offset parabolic antenna is selected so that antenna gain is maximum at the minimum operational elevation angle. Each primary feed is mechanically independent of the mobile reflector, is attached and fixed to a feed line. In the meantime, each reflector is turned based upon an azimuth axis and an elevation axis according to Az-EL mounting.

    Abstract: A liquid crystal display driver has a system of driving a plurality of segments with 1/n duty binary voltages. In the system, one frame period has the following three sub-periods; the first sub-period, where the line sequential driving is performed, the second sub-period, where adjustment is made on the segment voltage dispersion which occurs depending on display patterns, and the third sub-period, which is at the other time span than the first and the second sub-periods in the same frame period, where the potentials of the common signals and those of the segment signals are identical. With this driving method, constant Von/Voff ratio is obtained, and the contrast dispersion and crosstalk, which occur depending on a display pattern, are mostly eliminated. Then a good display quality is obtainable, and also the effective values of the voltages applied to the liquid crystal, are adjustable irrespective to the power source voltage.

    Abstract: Provided is a method for liquefying natural gas which can be applied to LNG plants of a wide range of capacity and can produce LNG both efficiently and economically. Feed gas of natural gas or a non-liquefied component of recycle gas which is produced during a process of liquefying natural gas is liquefied by using a first refrigerant, for instant consisting of a C3 refrigerant, and a second refrigerant which is different from the first refrigerant, for instance consisting of a C2 refrigerant, in a stepwise fashion. The flow is then liquefied by a substantially isentropic expansion process. The non-liquefied component remaining from this expansion process is then pressurized by a compressor, and combined with the non-liquefied component of the natural gas for recycling the combined flow. The compressor is driven by power obtained from the substantially isentropic expansion process.
