    摘要: A method for recovery of optically active tryptophane, which comprises filtering a solution of optically active tryptophane containing impurities through a semi-permeable membrane; adding a lower alcohol or a ketone to the filtrate; maintaining the solution containing the lower alcohol or ketone at an alkaline pH and a temperature higher than the .alpha./.beta. crystalline transition point; adding acid to the solution, thereby causing crystals of optically active tryptophane to form in the solution; and separating the crystals from the solution containing impurities, is disclosed. This method avoids the use of resins in the purification steps.

    摘要: To prevent a reduction in engine load detection accuracy due to variations in reluctor size within mass production tolerances, an engine control unit includes a pulse generator PC that detects a reluctor to output crank pulses. An angular velocity calculating unit calculates a first crank angular velocity on the basis of an interval between two crank pulses output in a predetermined section near compression top dead center TDC, and detects near overlap top dead center OLP the same reluctor used for calculating the first crank angular velocity to calculate a second crank angular velocity on the basis of an interval between generated two crank pulses. An engine load estimating unit calculates, as an engine load, a difference between the first crank angular velocity and the second crank angular velocity. The engine load is indicated mean effective pressure over a whole cycle including negative work done by the engine.

    摘要: An air-fuel ratio estimating device can include an amount of fuel injected calculating unit which can estimate the amount of fuel injected GF for each cycle on the basis of a driving time Tout of a fuel injection valve. A proportional constant calculating section determines a proportional constant K, using the estimated charging efficiency CE and the amount of fuel injected Gf, when the output value of a sensor is in a transition region R. When the sensor output value is not in the transition region R, an air-fuel ratio A/F is estimated from the determined proportional constant K, a charging efficiency CE calculated by a calculating section, and the amount of fuel injected Gf.

    摘要: An image forming apparatus includes a recording head, a main tank, a sub tank, a negative pressure state indicator, a position detector, and a sub tank position indicator. The recording head discharges recording liquid. The main tank supplies the recording liquid. The sub tank is supplied with the recording liquid from the main tank and supplies the recording liquid to the recording head. The negative pressure state indicator is displaced according to a negative pressure state of the sub tank to indicate the negative pressure state of the sub tank. The position detector detects the displacement of the negative pressure state indicator as position information. The sub tank position indicator is detected by the position detector and indicates a position of the sub tank without being displaced according to the negative pressure state of the sub tank.
