    摘要： An electromagnetic reciprocating pump having a piston electromagnetically moved at least in one direction is comprised of a frame having attached thereto an electromagnet which operates the piston, an inner cylinder whose one end side in the axial direction is secured to the frame and the other side thereof is closed and having the piston accommodated therein such that the piston can be reciprocated therein, an outer cylinder whose one end in the axial direction being secured to the frame and coaxially encircling the inner cylinder so as to form a working chamber between it and the inner cylinder, an outer piston accommodated within the working chamber so as to freely reciprocate and varying a capacity of working chamber, spring means being contracted and expanded in accordance with the movement of the outer piston, and magnetic coupling means for magnetically coupling the inner piston and the outer piston. The piston has a shape such that this piston does not form a pressure in the inner cylinder when reciprocated within the first cylinder. Further, the outer cylinder has a suction opening and a discharge opening, each having a valve, for sucking and discharging a special fluid, such as corrosive liquid, into and from the working chamber.

    摘要： There is provided a control circuit for a DC brushless motor suitable for use in acoustic devices or data cassette recorders which comprises a rotor magnet rotating synchronously with the motor rotor, three or more-phase stator windings opposing the rotor magnet and spaced apart therefrom by a slight gap, winding drive circuits for supplying exciting current to the stator windings, and Hall elements for detecting angular positions of the rotor magnet and producing output voltages supplied to the winding drive circuits. The control circuit further comprises a limit voltage setting circuit for setting two limit voltages respectively having upper and lower amplitudes which are symmetrically variable with respect to the central potential of the upper and lower amplitudes, an amplifier circuit associated with each of the Hall elements and amplifying the output voltage from the Hall element with respect to the central potential, and an amplitude limiter circuit limiting upper and lower amplitudes of the amplified output voltage from the amplifier circuit not to exceed the two reference voltages, thereby producing a trapezoidal waveform which in turn is applied to the winding drive circuit.
