摘要： A circuit for a clock having a time indicating mechanism is connected to regulate the driving of a DC motor by a predetermined amount at predetermined time intervals, so as to actuate the time indicating mechanism without being affected by the variation in the amplitude of the DC energizing voltage available for driving the motor and the variation in the load on the motor. The motor driving circuit has a timing pulse generating circuit for generating timing pulses at the predetermined time intervals, a holding circuit actuated by the timing pulse applied thereto by the timing pulse generating circuit so as to be self-held thus enabling the motor to be energized from the DC energizing voltage, and switching means, connected to the motor or the time indicating mechanism so as to be actuated when the motor is driven by the predetermined amount. The switching means is connected to the holding circuit, so that the holding circuit is deactivated to terminate the self-holding when the switching means is actuated upon completion of the driving of the motor by the predetermined amount, thereby also terminating the energization of the motor from the DC energizing voltage.

摘要： A screw compressor capable of increasing a pressure receiving area of a balance piston, employing a thrust bearing having a large load capacity, and preventing an occurrence of a reverse thrust load state when started. The rotor shaft extending beyond both sides of screw rotors 11, 12 is rotatably supported by radial bearings 13, 14. An input shaft 15 serves as a rotor shaft on the suction side. A rotor shaft on the discharge side is rotatably supported by a thrust bearing 16 at a position farther away from the screw rotors 11, 12 than the radial bearing 14. A balance piston 17 is mounted on the rotor shaft at a position farther away from the screw rotors 11, 12 than the thrust bearing 16. A partitioning wall 31 is provided between the thurst bearing 16 and the balance piston 17. An equalizing flowpassage for directing oil from an oil reservoir of an oil separating and recovering unit provided in the discharge flowpassage without pressurizing it, is provided in a space adjacent the partitioning wall 31 of the balance piston 17.
