Abstract: A method providing for the selective hydroprocessing of cracked naphtha feedstock to make a low-sulfur gasoline blending component. The method includes the use of two catalytic distillation stages in combination with two stripping columns and two fixed-bed reactors integrated in a novel arrangement so as to provide for the treatment of cracked naphtha feedstock that has a high sulfur concentration to yield exceptionally low-sulfur light cracked naphtha and heavy cracked naphtha products. The desulfurized light and heavy cracked naphtha are produced with a minimal amount of hydrogenation of the olefin content and at may suitably be used as gasoline blending components.

Abstract: A control apparatus for an internal combustion engine, which, in the case of intake-side and exhaust-side cleaning controls being performed, is capable of ensuring stable combustion of a mixture when the engine is returned from a decelerating FC operation to a normal operation, thereby making it possible to enhance marketability. The control apparatus for the engine includes an ECU. The ECU performs intake-side cleaning control for controlling an intake cam phase CAIN to a predetermined most advanced value CAIN_ADV so as to increase a valve overlap period of an intake valve and an exhaust valve, and performs exhaust-side cleaning control for controlling an exhaust cam phase CAEX to a predetermined most retarded value CAEX_RET so as to increase the valve overlap period of the intake valve and the exhaust valve. Further, during execution of one of the intake-side and exhaust-side cleaning controls, the ECU inhibits execution of the other.

Abstract: A communication network includes base stations. Each base station includes a BS function unit, a terminal function unit, a transfer unit, and an antenna. The antenna receives first uplink data from a subscriber terminal and downlink data transmitted from another base station and transmits downlink data to another base station or a subscriber terminal. The terminal function unit converts the downlink data received by the antenna to second uplink data. The BS function unit demodulates and outputs the first uplink data or the second uplink data as first data, and modulates input second data into downlink data and transmits the downlink data from the antenna. The transfer unit recognizes a communication destination of the first data, and, when a transfer of the first data is required, outputs the first data to the BS function unit as second data.
