Title: Coal liquefaction process
Inventor: KANESHIRO TSUNEO
IPC: C10G1/06
Filed: 1982-06-07
Abstract: PURPOSE:To provide a coal liquefaction process in which corrosion of towers and tanks is prevented by controlling the process flow and the process conditions so that the corrosive substances present in fluid within the process and corrosive environments may be placed under control. CONSTITUTION:A mixture of coal 1 with a circulating solvent 2 and a hydrogen- rich gas are fed for interaction in a high-temperature and high-pressure reaction zone. After condensation and separation, coal liquefaction product 28, insoluble coal product 2, solvent 22 and gas 4 are obtained. In a system where water, oil and corrosive substance are present, corrosion is prevented by keeping the temperature at such a level that the water may be vaporized. In the 1st condensation zone, for example, water is not condensed and the solvent only is condensed when the temperature is maintained higher than t deg.C shown in equation I . M in the equation I is shown by equation II (where P is the total pressure in the 1st condensation zone; VG is gas flow rate; XW is water content of coal; XS is water content of solvent; Wcoal is feed rate of coal; WS is amount of solvent; K is 0.1-0.5).

Title: Prevention system for generation of overvoltage output of stabilized power supply
Inventor: YOSHIDA MASAHIRO
IPC: G05F1/571
Filed: 1982-06-09
Abstract: PURPOSE:To prevent the deterioration of reliability for the load operation, by providing two sets of error amplifiers in parallel to each other and a means to clamp mutually the output side potentials of said amplifiers and threrefore avoiding the generation of the overvoltage higher than the rated voltage. CONSTITUTION:Two sets of error amplifiers are provided in parallel to each other, and their output side potentials are clamped with each other. At the same time, the difference of potential is detected between outputs of two sets of error amplifiers. Then the operation of a switching control circuit is stopped when said potential difference exceeds a prescribed limit. That is, if the output voltage of a power supply produces an error to the reference voltage 11 of an error amplifying circuit 10, the outputs E1 and E2 of error amplifiers 12 and 13 vary to reduce the error of the output voltage. Then the mean value of the outputs E1 and E2 is supplied to a switching control circuit via resistances R1-R4 to compensate the output voltage value. When the voltage difference between inputs (a) and (b) exceeds a difxed range, a fault detecting circuit 20 delivers a switching stop command to a switching control circuit via an OR gate 21.

Abstract: PURPOSE:To easily obtain a phase locked loop circuit possible to hold a state before change without retrying phase locked loop control by providing a phase correction means to operate a feedback signal with a prescribed phase correcting quantity when abnormality is generated in the phase of an input signal. CONSTITUTION:As the phase correction means, a phase correction signal generator 1 and an adder 2 are provided. The generator 1 monitors the phase relation of a reference phase set internally by receiving an input sine wave signal 801 impressed on an input terminal 101 with the input signal, and generates a prescribed phase correction signal corresponding to a phase difference replying to the phase change of the input signal, and supplies it to the input on one side of the adder 2. The adder 2 performs addition or subtraction between the phase correction signal and the output 605 of a VCO supplied to the input on the other side, and supplies the result to a phase comparator 102 as the feedback signal. As a result, a phase offset before and after the phase change of the signal 801 is off set, and the phase locked loop state of the output 605 before the phase change can be maintained.
