    摘要: A multiple electron emission device having a substrate, a pair of opposed electrodes disposed on the substrate, and an electron emission section formed with grains between the electrodes. Selected portions of the electron emission section are coated with a conductor, semiconductor or insulating material by mask deposition or the like so as to divide the electron emission section into a dotted or linear array of electron emitting portions.

    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.
