Masaharu Tomiyama has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7676312
    Abstract: An actuator controller includes an actuator body to be driven in a predetermined driven range, an actuator driving unit; and a controller body for controlling the driven position of the actuator body. The controller body includes an instructing signal outputting zone configured to outputting a position instructing signal for instructing the driven position of the actuator body according to a bid, excluding arbitrary two bits among the predetermined bit counts, an normal direction forcedly driving signal for instructing a normal direction forcedly driving to drive the actuator body in a predetermined direction with the one of the arbitrary two bits, and a reverse direction forcedly driving signal for instructing a reverse direction forcedly driving to drive the actuator body in a direction reverse to the predetermined direction with the other arbitrary bit.

  • Patent number: 7317304
    Abstract: An inductive load driving device includes two inductive loads (20A, 20B) connected to a power source (21), two switching elements (15A, 15B), which are connected in series to the two inductive loads, respectively, their on/off are controlled by a pulse width modulation signal, respectively, and a control device (30), which outputs the pulse width modulation signal to each of the two switching elements, and the pulse width modulation signal is configured such that a rising edge of one pulse of the pulse width modulation signal to be output to one switching element starts between an end point of a rising edge and a start point of a trailing edge of one pulse of the pulse width modulation signal to be output to the other switching element, and a time from a start point of a trailing edge to an end point of the trailing edge of the one pulse of the pulse modulation signal to be output to one switching element does not overlap with a time from the start point of the trailing edge to an end point of the trailing ed
