Abstract: PURPOSE: The catalytic oxidation of an unsaturated aldehyde in gas phase is conducted using a catalyst whose activity reduction caused by impurities as olefins is prevented by adding Cu, Cd or others, thereby producing a carboxylic acid in high yield for long periods of time.  
     CONSTITUTION: The catalytic oxidation of an unsaturated aldehyde as acrolein with oxygen in gas phase is conducted in the presence of a catalyst of the formula (A is K, Rb, Cs, Tl; B is Cu, Cd, Sn, Bi, and other; a, g, c, d, e, f are 0.05W12; g is number of oxygen atoms) to produce the corresponding unsaturated carboxylic acid.  
     EFFECT: As the reduction in catalyst activity can be substantially prevented in spite of the presence of a little amount of unsaturated hydrocarbons, the oxidation product from an olefin can be directly fed for the formation of carboxylic acid without purification before or after the aldehyde formation.

Abstract: PURPOSE: To represent the reliability of the probability of a phenomenon on the neural network in addition to the probability and to obtain a neural network which is high in safety and reliability by enabling the output of a neuron to have a specific value corresponding to the potential at which the neuron is coupled. CONSTITUTION: This neural network is equipped with neurons N1-N3 which determine output values in probability according to input pulse signals and connections W13 and W23 which convert the outputs of the neurons N1-N3 into pulse signals and outputs the pulse signals as inputs to other neurons.

Filed: 1990-01-22
Abstract: PURPOSE:To reduce leak current by inserting a reactor into an AC line and connecting at least one phase of the AC line through a capacitor with a DC line thereby constituting a high frequency filter. CONSTITUTION:Reactors 6, 7, 8 are inserted into AC lines A, B, C and at least one phases of the AC lines A, B, C are connected through capacitors 9, 10, 11 with DC lines P, N thus constituting a high frequency filter. Transistors T1-T6 are then subjected to high frequency switching thus absorbing the high frequency voltage for the AC and DC lines A-C, P, N through the reactors 6-8 and the capacitors 6-8. Since a low frequency voltage functions between the AC and DC lines A-C, P, N, the stray capacitance between the DC lines P, N and the ground does not produce a leak current which causes any trouble.
