There is provided an idle stop system that can more quickly restart with small noise in conducting idle stop. In preparation for a restart request during an engine inertial rotation, after a motor is rotated in a state where a starter motor is not coupled to the engine, a pinion is engaged with a ring gear during the motor is subjected to inertial rotation like the engine. In this situation, the rotational speed including future pulsation of the engine is estimated with the use of information on the crank angle, and a pinion pushing timing is controlled so that the pinion and the ring gear contact each other with a given rotational speed difference taking a delay time of a pinion pushing unit into consideration.

An exhaust aftertreatment system comprises an injector for injecting urea water into an exhaust duct, and a denitration catalyst disposed downstream of the injector with respect to a flow of exhaust gas. The exhaust aftertreatment system reduces nitrogen oxides in the exhaust gas by the denitration catalyst while using ammonia produced from the urea water injected from the injector. The urea water is injected along a direction of the flow of the exhaust gas within the exhaust duct, and a porous plate is disposed in multiple stages in a space of the exhaust duct such that droplets of the injected urea water impinge against the porous plate before reaching a wall surface of the exhaust duct. A surface of the porous plate subjected to the impingement of the droplets is arranged to face downstream with respect to the flow of the exhaust gas. Deposition of the urea water is prevented by causing film boiling when the droplets impinge against the porous plate, and the urea water reflected by the porous plate is uniformly dispersed into the exhaust gas. Thus, the urea water is uniformly dispersed into the exhaust gas without increasing a pressure loss of the exhaust gas. The urea water is prevented from depositing on the wall surface and producing a precipitate in the form of a solid.

摘要:
A process of extracting vegetable oil and fat from an oleaginous raw material which comprises the steps of obtaining flakes having a moisture content of from 0.7 to 10 weight % from an oleaginous raw material; contacting the flakes with an ethanol solution containing not less than 90 weight % ethanol at a temperature in the range of from 70.degree. C. to the boiling point of the ethanol solution, thereby obtaining a miscella; cooling the miscella, thereby obtaining vegetable oil or fat and a separate defatted miscella; drying the defatted miscella with a molecular sieve material having a pore size of from 3 .ANG. to 4 .ANG., thereby obtaining a second ethanol solution wherein the second ethanol contains less than 7 weight % water; and using the ethanol solution obtained in the drying step as the ethanol solution of the contacting step in a second extraction.
摘要:
A multi-function sound system including an AM stereophonic receiving function in which interference with operating circuits in modes other than the AM stereophonic mode is eliminated. A limiter receives a IF AM stereophonic received signal and removes the amplitude variation components therefrom and couples the resulting signal to a phase detector composed of a phase-locked loop which produces as an output signal a sub-signal. A switch is provided which deactivates both the limiter and the voltage-controlled oscillator in the phase-locked loop circuit when the sound system is set to other than the AM stereophonic receiving mode.

A voltage controlled attenuator includes a control circuit having variable impedance means whose impedance varies in a stepwise fashion as an input voltage is varied. In this manner, the attenuation characteristic of the attenuator can be made to vary stepwise in slope or inclination to improve its efficacy for use as a volume control device in audio apparatus.

An automatic water feed mechanism and method is provided by equipping a lavatory with a two dimensional sensor array such as a camera unit for monitoring a target area that a user may enter. An infrared emitter and an infrared detector can also be activated at low light levels. A two dimensional image signal can be processed and compared with a stored reference signal for activating the release of water. At a low ambient light, the infrared emitter unit can be activated to emit infrared rays which can then be detected when reflected by a user by the infrared detector. Such a detection can provide an alternative release of water.
