摘要： There is provided a control system for an electric motor to which electric power is supplied from a DC power supply via a multi-phase inverter, the multi-phase inverter including switch units respectively provided on a positive side and a negative side of arms corresponding to respective phases, each switch unit including a switching element and a reflux diode connected in parallel thereto. The control system comprises a phase current detection unit for detecting phase currents which flow between the inverter and the electric motor, a DC component acquiring unit for acquiring DC components of the respective phase currents, and a short-circuiting determination unit for determining that a short-circuit failure occurs in the inverter when at least one of the DC components of the phase currents acquired by the DC component acquiring unit exceeds a threshold. Consequently, the short-circuit failure of the inverter can be detected even though the control of the electric motor is stopped.

摘要： In the lens drive unit; the position retaining parts are advanced by rotating the position retaining member, which is held in the case body in such a manner as to become rotatable, in the R direction so that the position retaining parts are positioned just under the protrusion parts of the movable lens body, and eventually the movable lens body can be retained at the middle position. Furthermore, the through-holes are advanced by rotating the position retaining member in the R direction so that the through-holes are positioned just under the protrusion parts of the movable lens body, and eventually the protrusion parts loosely get fitted into the through-holes of the position retaining member to enable the body tube holder to move downward.

摘要： A common objective lens typically used in reading data from different optical data storage media that are responsive to laser beams of different wavelengths, such as CD and DVD is provided. The lens has a refracting surface with inner and outer refracting surface regions. Diffraction gratings are provided in both the inner and outer refracting surface regions with each having a differential optical path function. The inner diffraction grating and at least a part of the outer diffraction grating emit an order of diffracted beams which have different polarities to cancel out any spherical aberrations caused by a change in temperature.
