  • Patent number: 10703404
    Abstract: In an electric power steering device, if a semiconductor switching element is used between a battery and a bridge circuit for opening and closing a current path, this arises a problem of generation of heat by an ON resistance; for this reason, a current flowing through the semiconductor switching element is limited if a difference between the gate voltage and the source voltage of the semiconductor switching element is smaller than or equal to a predetermined value.

  • Patent number: 10681659
    Abstract: It takes a processing time to perform a security process on a time synchronization message, thus the difference of a delay time required for the security process can be made between a time at which the time synchronization message is actually transmitted and a transmission time assigned to the time synchronization message, and therefore, the difference between the actual transmission time of the time synchronization message and the assigned transmission time needs to be reduced. In generation of a secure time synchronization message in the synchronization system according to embodiments of the present invention, most of the security processes is performed in an upper layer which is an MAC layer or a higher layer, and processes including the assignment of the transmission time and assignment of authentication information for authenticating validity of the transmission time are performed in a physical layer.

  • Patent number: 10668725
    Abstract: Printheads for jetting a print fluid. In one embodiment, a printhead includes a main body configured to attach to a stack of plates, where the stack of plates forms a row of jetting channels configured to jet droplets of a print fluid. The main body includes a supply manifold configured to provide a fluid path for the print fluid to the row of jetting channels. The supply manifold comprises a primary manifold duct and a secondary manifold duct that extend in parallel in alignment with the row of jetting channels. The primary manifold duct is fluidly isolated from the secondary manifold duct at end sections of the primary manifold duct, and is fluidly coupled to the secondary manifold duct toward a midsection of a length of the primary manifold duct. The secondary manifold duct is fluidly coupled to the row of jetting channels.

  • Publication number: 20200130097
    Abstract: An aluminum plate (103) is overlaid on a steel plate (102). A distal end (113) of a button component (101) is pushed in from the obverse surface side of the aluminum plate (103), and the distal end (113) is abutted against the steel plate (102) by applying a first pressure to the button component (101) made of steel without heating. The distal end (113) of the button component (101) and the steel plate (102) are welded by resistance spot welding while applying a second pressure lower than the first pressure to the button component (101).

  • Publication number: 20200061988
    Abstract: Devices and method for performing temperature measurements in a printhead. In one embodiment, a printhead includes at least one row of jetting channels configured to jet droplets of a print fluid using piezoelectric actuators. A drive circuit includes an input voltage generator that applies a step voltage to a piezoelectric actuator of a jetting channel, and an output voltage detector that detects an output voltage across the piezoelectric actuator over time in response to the step voltage. The drive circuit also includes a temperature detector that determines a voltage response to the step voltage at the piezoelectric actuator based on the output voltage over time, and determines a temperature measurement for the piezoelectric actuator based on the voltage response of the piezoelectric actuator.
