摘要： A series resonant drive circuit for a magnetic bubble memory includes X- and Y-coils arranged orthogonally to each other for generating a rotating magnetic field applied to a magnetic bubble memory chip, resonance capacitors each connected to a corresponding one of the X- and Y-coils for forming a series resonance circuit with the corresponding coil at a frequency of the rotating magnetic field, power supplies each connected to a corresponding one of the resonance circuits, and an inductance device connected in series with both of the resonance circuits and a capacitance device connected between the resonance circuits to compensate a mutual inductance due to the inductive coupling between the X- and Y-coils and a capacitance due to the capacitive coupling between the X- and Y-coils. Further, the temperature coefficient of the capacitance device is selected so that the temperature coefficients of the mutual inductance and capacitance between the coils can be compensated.

摘要： The present invention provides an improved method and apparatus for driving a magnetic bubble device, in which a d-c voltage supply and drive coils are connected to a bridge circuit consisting of four bi-directional switches, and alternating currents with steps (such as currents consisting of triangular waves or trapezoidal waves) are produced in the drive coils by suitably controlling the turn on or off of the bi-directional switches. As a result, the d-c level in the alternating current is not shifted by the variation in width of pulses which control the opening and closing of the bi-directional switches, and the magnetic bubble device is provided with a greatly improved operation margin.

摘要： An injection timing control system for a fuel-injection pump for an engine has a phase angle regulator for varying the rotational phase angle of a drive shaft of the fuel-injection pump. The regulator has a cylindrical extension of one of an input shaft adapted to be driven by the engine and an output shafts for driving the drive shaft of the pump coaxially surrounding an end portion of the other shaft in spaced apart relationship. A male spline and female spline are formed respectively on the end portion and the extension over some axial length thereof, at least one of the splines being a helical spline. A slider is located in an annular space between the splines and formed with splines meshing therewith respectively. An annular cylinder is formed between the substantial parts of the rest axial length portions of the cylindrical extension and end portion. A piston is reciprocally received in the cylinder, the slider and piston being formed as a unit.
