  • Patent number: 7352173
    Abstract: External magnetic members are provided outside the outer periphery of a rotor. When the rotor is positioned around its turning angle of 70 degrees, part of the magnetic fluxes generated by magnets pass through the external magnetic members. This makes it possible to reduce the magnetic fluxes passing through Hall ICs around the turning angle of 70 degrees, thereby linearizing the change characteristic of the magnetic flux density. Thus, it is possible to generally linearize the change characteristic of the density of the magnetic fluxes through the Hall ICs 7, with the detectable angle range kept wide.

  • Publication number: 20070296307
    Abstract: In a driving device for a piezoelectric actuator, when a driving signal is input, a charging switch is repetitively turned on/off to charge and expand the piezoelectric actuator under the state that a discharging switch is turned off. Thereafter, when the input of the driving signal is stopped, the discharging switch is repetitively turned on/off under the state that the charging switch is turned off, thereby discharging and contracting the piezoelectric actuator. Particularly, during the charging period, the charging switch is turned on at a fixed period, and the charging switch is turned off when an integration value of current flowing in a charging circuit at the ON-time of the charging switch reaches a target charge amount.
