Abstract: WHEN A LOCK DETECTING MEANS 17 DETECTS A LOCKED STATE OF A DC MOTOR 4 IN A STARTING STAGE, A TORQUE INCREASING MEANS 18, 27, 29 OR 31 IMMEDIATELY SELECTS A STARTING SEQUENCE PATTERN OF AN OUTPUT TORQUE THAT IS GREATER BY ONE STEP, AND OUTPUTS THE SAME TO A STARTING SEQUENCE CONTROL MEANS 13, SO THAT A COMPRESSOR 5 CAN BE RESTARTED SPEEDILY WITHOUT REPEATING STARTING FAILURES. A COMPRESSOR 41, DRIVEN BY A DC MOTOR 43, HAS A SHELL OF AN INTERNAL PRESSURE APPROXIMATELY EQUAL TO THE PRESSURE OF AN INHALATION GAS. AN INVERTER 53 IS PROVIDED TO MAKE THE SPEED OF THE DC MOTOR 43 VARIABLE. A ROTATIONAL FREQUENCY SETTING CURCUIT 56 SETS THE ROTATIONAL FREQUENCY OF THE DC MOTOR 43 TO A FREQUENCY THAT IS NOT GREATER THAN THE FREQUENCY OF A COMMERCIAL POWER SOURCE WHEN THE INTERNAL TEMPERATURE OF A REFRIGERATOR IS STABILIZED. BY THIS CONSTRUCTION, THE POWER CONSUMPTION CAN BE REMARKABLY REDUCED.

Abstract: WHEN A LOCK DETECTING MEANS (17) DETECTS A LOCKED STATE OF A DC MOTOR (4) IN A STARTING STAGE, A TORQUE INCREASING MEANS (18, 27, 29 OR 31) IMMEDIATELY SELECTS A STARTING SEQUENCE PATTERN OF AN OUTPUT TORQUE THAT IS GREATER BY ONE STEP, AND OUTPUTS THE SAME TO A STARTING SEQUENCE CONTROL MEANS (13), SO THAT A COMPRESSOR (5) CAN BE RESTARTED SPEEDILY WITHOUT REPEATING STARTING FAILURES. A COMPRESSOR (41), DRIVEN BY A DC MOTOR (43), HAS A SHELL OF AN INTERNAL PRESSURE APPROXIMATELY EQUAL TO THE PRESSURE OF AN INHALATION GAS. AN INVERTER (53) IS PROVIDED TO MAKE THE SPEED OF THE DC MOTOR (43) VARIABLE. A ROTATIONAL FREQUENCY SETTING CIRCUIT (56) SETS THE ROTATIONAL FREQUENCY OF THE DC MOTOR (43) TO A FREQUENCY THAT IS NOT GREATER THAN THE FREQUENCY OF A COMMERCIAL POWER SOURCE WHEN THE INTERNAL TEMPERATURE OF A REFRIGERATOR IS STABILIZED. BY THIS CONSTRUCTION, THE POWER CONSUMPTION CAN BE REMARKABLY REDUCED.
