Title: Oa machine having preliminary operation mode
Inventor: BABA MASANORI
IPC: B41J11/42
Filed: 1992-02-19
Abstract: PURPOSE:To make it possible to equalize a machine, which can not operate normally due to overload caused by stagnant assemblage, to a machine operating under normal load by making a decision that components are assembled stagnantly if step-out is detected when a newly assembled step motor(SM) is driven and then performing preliminary operation of the SM at low speed for a predetermined time. CONSTITUTION:When a decision is made of step-out, a signal is fed from a step-out detecting circuit 4 to a control circuit 2. The control circuit 2 then commands an operation control circuit 5 to perform preliminary operation of the SM1 through an SM driving circuit 3. Preliminary operation is performed while lowering the driving speed but since step-out may occur due to some other cause, an operating time is set while assuming a time required for the preliminary operation. When an assemblage of components is driven forcibly with high torque, the components interact smoothly to eliminate overload due to stagnant assemblage thus equalizing the machine to that operating under normal load.

Abstract: PURPOSE: Raw brown coal is made into slurry by mixing with an appropriate solvent and dehydrated and then the liquefaction reaction is effected, thereby carrying out high-heat-efficiency dehydration to produce dehydrated slurry suitable for conducting high-efficiency liquefaction reaction without the exposure of slurry to the air.  
     CONSTITUTION: Raw brown coal is sufficiently kneaded with a low-boiling solvent and another high-boiling solvent in kneader 1 and made into a slurry in slurry tank 2. The slurry is prehaeted in heat exchanger 4 by pumping with pump 3 into the heater and further heated to about 100-300°C in the upper part of heating furnace 5. Then the slurry is sent to gas-liquid separator 6 under such a pressure that the water in the slurry evaporate sufficiently to separate into steam, the low-boiling solvent and slurry. The resulting slurry is pumped through furnace 5 and the pressure and temperature are raised, then charged into liquefaction reactor 10. The steam from the reactor is passed through pressurizing means 7 and sent to heat exchanger 4 to preheat the slurry. The low-boiling solvent recovered in oil- water separator 9 and the liquid fraction from separator 11 are subjected to fractionation disillation in rectification column 12. The recovered high-boiling solvent is reused for making slurry.

Title: Detecting circuit for interruption of electric power service
Inventor: KIDOGUCHI HIDETAKA
IPC: G01R19/165
Filed: 1989-02-10
Abstract: PURPOSE:To detect a voltage drop condition of single-phase AC power supply in a promptly responding manner by deciding whether the peak value of an output waveform made from a fullwave rectification for the single-phase AC voltage of the power supply is larger than a certain level or not. CONSTITUTION:The single-phase AC voltage of single-phase AC power supply 1 is fullwave-rectified by a fullwave rectifier circuit 2. A repeating cycle of the output waveform at the rise point of a pulse waveform, the width of which is a period during the output waveform is larger than a certain voltage level, is a half of the AC voltage cycle which is constant when the AC voltage is not varied. Then a comparative decision is made for the peak value of the output waveform with the comparison voltage of a detection level setting device 3 by a comparator 4, and one shot pulse having the width slightly longer than a half of the AC voltage cycle is outputted in a single stable multivibrator 5. A continuity of this one shot pulse is decided by a latch circuit 6 to detect an abnormality for voltage drop of the single-phase AC power supply. The time required for the abnormality detection can be thus shortened to a half cycle of the AC voltage.

Abstract: PURPOSE:To control current smoothly by a method wherein a thyristor converter and a diode converter are subjected to a cascade connection at DC side, and a current fluctuation to arise in conjunction with a DC output voltage of the diode converter being zero instantaneously is suppressed. CONSTITUTION:When a trip signal 51 of an AC breaker 2-2 is generated to get the AC breaker 2-2 in contact parting due to a necessary DC output voltage having dropped below output voltage of a thyristor converter, output voltage of a diode converter 5 becomes zero. And when voltage comes below a constant value due to a voltage value from a voltage detector 10, a level detection circuit 11 decides that output voltage of the diode converter 5 has just been zero, closes an analog switch 12, inputs a signal 52 corresponding to output voltage of the diode converter 5 to an output of a current controlling circuit 7 as bias through interruption, advances a firing angle of the thyristor converter 4 instantaneously, and thus a voltage equivalent to that of the diode converter 5 is corrected instantaneously with the thyristor converter 4.
