摘要： A motor-driven power steering system for a motor vehicle implemented inexpensively in a simplified structure allows operation of a steering assist torque generating motor even in the vicinity of a neutral point while preventing rotation of the motor in a direction reverse to the steering direction as well as self-rotation of a steering wheel notwithstanding of occurrence of abnormality in a controller implemented by a CPU. The motor-driven power steering system includes a CPU (3) for controlling a motor (2) in dependence on output of a steering torque detecting unit (1), an interlock means (5) for limiting driving operation of the motor (2) upon occurrence of abnormality in the CPU (3), and a motor driving means (6) for driving the motor (2) in accordance with commands issued by the CPU (3).

摘要： An electric power steering device constructed to detect a steering force by a driver and a vehicle speed respectively by a torque sensor and a vehicle speed sensor, set a steering force assisting current for a motor by a steering force assisting current setter using the detected steering force and the detected vehicle speed, set an upper limit value of a motor current by a motor current upper limit value setter based on a power function of a deviation between the set steering force assisting current and a predetermined motor current reference value, and perform overheat protection by setting an upper limit of a motor current applied by a motor driving circuit based on an integrated value of the motor current squared, whereby a problem of an insufficient steering assisting force when stationary steering is repeated many times while parking in a garage in a narrow parking area is solved.

摘要： Printheads and methods of operation. In one embodiment, a printhead includes a plurality of jetting channels comprising first jetting channels configured to jet a first print fluid and second jetting channels configured to jet a second print fluid, and a driver circuit communicatively coupled to actuators of the jetting channels. The driver circuit receives a drive waveform comprising non-jetting pulses and jetting pulses, and gating signals comprising a first active gating signal designated for jetting the first print fluid, and a second active gating signal designated for jetting the second print fluid. The driver circuit selectively applies the non-jetting pulses and the jetting pulses to actuators of the first jetting channels based on the first active gating signal to jet the first print fluid, and selectively applies the jetting pulses to actuators of the second jetting channels based on the second active gating signal to jet the second print fluid.

摘要： An inkjet head that is able to circulate ink. The inkjet head includes a diaphragm plate, a first restrictor plate, one or more chamber plates, a second restrictor plate, and an orifice plate. The orifice plate forms a plurality of nozzles. The chamber plates form a plurality of chambers corresponding with the nozzles, and also form a return manifold for receiving ink from the chambers when circulating the ink through the inkjet head. The diaphragm plate forms a diaphragm that seals the chambers. The first restrictor plate controls a flow of ink between the chambers and the return manifold to circulate the ink through the inkjet head. The second restrictor plate controls the flow of ink between a supply manifold and the chambers.

摘要： In a communications apparatus, a communication controller transmits and receives signals on any of plural channels. A channel switching controller is responsive to channel switching information selectively defining plural reception-waiting periods using the channels to alter a channel to be used by the communication controller. A neighboring node channel controller exchanges channel switching information with other nodes to manage the channel switching information received from the other nodes. When transmitting transmission signals, a transmission controller refers to the channel switching information of the other nodes, and controls repetitive transmission of the transmission signals on the channel thus searched for.
