    • A permanent-magnet rotating machine includes a rotor having a rotor core carrying on a curved outer surface multiple permanent magnets arranged in two rows along an axial direction. The permanent magnets in one row are skewed from those in the other row in a circumferential direction by a row-to-row skew angle (electrical angle) θe. A stator having a tubular stator core in which the rotor disposed includes stator coils for producing a rotating magnetic field for rotating the rotor. A lower limit of the row-to-row skew angle θe larger than 30 degrees (electrical angle). A ratio of cogging torque occurring in the absence of skew to cogging torque occurring when the permanent magnets are skewed, at a row-to-row skew angle of 30 degrees is calculated based on the cogging torque ratio, the row-to-row skew angle θe, and B-H curve properties of the stator core. An upper limit of the row-to-row skew angle θe is not larger than the maximum value at which the cogging torque ratio does not exceed the calculated cogging torque ratio at 30 degrees.

    • A capping apparatus includes a capping head 3 which is provided with a rotatable spindle. A plurality of permanent magnets 51 are embedded around the entire outer periphery at the upper end of the spindle, with adjacent permanent magnets 51 presenting magnetic poles of different polarities. An arcuate rotation imparting member 53 is fixedly mounted and includes a plurality of permanent magnets 55 which are disposed along a locus of travel of the permanent magnets 51 on the capping head 3, with adjacent permanent magnets 55 presenting magnetic poles of different polarities. As the capping head 3 moves through a threadable engaging zone C in a direction indicated by an arrow, coaction between the permanent magnets 51 and 55 causes the capping head 3 to rotate clockwise, thereby causing a cap 12 to be threadably engaged with a container 4. The permanent magnets 51 and 55 form together a drive source which is free from a sliding movement, thus preventing a occurrence of abraded powder and avoiding a contamination of the environment of a working area.

    • An arithmetic operation circuit provided in a delta-sigma modulator of a delta-sigma A/D converter includes two reference capacitors which are respectively provided at a positive side input node and a negative side input node of an operational amplifier. When a signal corresponding to an output of the modulator is added or subtracted to or from an input signal, the amount of charge added to the input node of the operational amplifier is made to be always the same regardless of the reference voltage by complementarily switching the connection of the reference capacitors at the positive side input node and the negative side input node, and thereby the potential of the input node of the operational amplifier is made to converge to the common mode potential of the circuit.
