Abstract: A control circuit for invertor, which is capable of compensating an instantaneous variation of the power system without decreasing of the stability of the control circuit upon the synchronous-interconnection mode being in advance of interconnection mode. The control circuit for an invertor converting DC voltage to AC voltage operable in an individual mode and an interconnection mode, includes a synchronous compensating circuit in which when the invertor is operating in a power system synchronous operation mode under control of the synchronous-interconnection control system, a quantity of an instantaneous voltage variation occurring in the power system is separated into a quantity of the variation of the component in same phase with a reference voltage vector of the output voltage of the invertor and a quantity of the variation of the component orthogonal to the reference voltage vector in order to detect respectively, and the detected variation quantities are respectively added to the outputs of a voltage adjuster and a phase adjuster in the synchronous-interconnection control system.

Abstract: Disclosed is apparatus for sensing the end of travel of curtain drawn by a cord and associated electric motor (103). The apparatus consists of an assembly (100), including the motor (103), in which a sensing member (3;200) is mounted for rotation about a hollow boss (120) carried on a face (101) of the assembly, and through which the motor drive shaft (2) extends. A cord drive pulley (4) is carried at the end of the drive shaft (2) adjacent the sensing means (3;200); a beam member (20;210) is pivotally mounted (21;222) on the sensing means (3;200) above the drive pulley (4) and carries guide pulleys (22, 23) rotatably mounted at each end thereof such that they are spaced apart from the drive pulley (4). The curtain cord (31, 32) is passed between the guide pulleys (22, 23) and looped about the drive pulley (4). When the curtain reaches the end of its travel tension in the end of one cord run (31, 32) increases causing the beam (20; 210) to pivot and bring one of the guide pulleys (22, 23) adjacent the drive pulley (4) such that the cord run (31, 32) is pinched between the said guide (22, 23) pulley and the drive pulley (4) whereby the sensing (3; 200) means is caused to rotate about the hollow boss (120) against resilient means (10; 232, 233). A switch (8) in the motor drive circuit and positioned in the assembly is associated with means (5, 6, 7;) secured to the sensing member (3,200) and is opened in response to a predetermined degree of rotation of the sensing member (3,200) to stop the motor drive (103). The resilient means (10; 232, 233) acting against the sensing means (3; 200) control the degree of rotation of the sensing means (3;200), and further means (14, 15; 234) are provided to act on the resilient means (10,232,233) and vary the force acting between the said means (10,232,233) and the plate (3) whereby the tension in a cord run (31, 32) required to cause rotational movement of the sensing means (3; 200) can also be varied.

Abstract: A state of an Operation of cutting a rubber sheet (1) having a number of parallel cords (2) embedded therein by moving a cutter (31) in a cutting direction which is in parallel with the direction in which the cords extend is detected by monitoring a first displacement of the cutter in the direction of the thickness of the rubber sheet and a second displacement of the cutter in a direction perpendicular to the cutting direction. When the first displacement of the cutter exceeds a predetermined threshold value, there is produced a comparison signal having a predetermined time period. In response to the comparison signal, the second displacement of the cutter is compared with a second threshold value within the time period of the comparison signal, and when the second displacement of the cutter exceeds the second threshold value, there is produced an alarm signal which represents that the cutting operation is not carried out correctly.

Abstract: Apparatus and method for controlling spindle motor of compact disc utilizing appliance, in which the spindle motor is early controlled to meet a rotation speed on a target track, in a rough search, so that a phase locked loop (PLL) servo is normally operated, immediately after the search, thereby enabling the time required in accessing information to be reduced. 
     The apparatus includes a device for detecting the rotation speed of the spindle motor. In the search mode, the frequency corresponding to the detected rotation speed of spindle motor is compared with a reference frequency corresponding to a rotation speed on the target track. A signal indicative of the comparison result is differentially amplified, to control the spindle motor to correspond to the rotation speed on the target track, in the search mode. After a compact disc has been loaded, the rotation speed on a track corresponding to a reference position at which a reference value is set is detected, so that the inherent deviation in constant linear velocity is calculated, based on the reference value, and corrected upon calculating the number of tracks.
