  • Patent number: 11249476
    Abstract: A steering holding determination device determines a steering holding state in which a driver of a vehicle holds a steering wheel of the vehicle in a steerable manner. The device includes a torque recognition unit that recognizes a steering torque based on a detection result of a torque sensor, a contact state recognition unit that recognizes a contact state or a non-contact state, a threshold value setting unit that sets a threshold value used for the steering holding state determination, based on a recognition result of the contact state recognition unit, and a steering holding determination unit that determines that the driver is in the steering holding state, when the steering torque is equal to or greater than the threshold value. When the non-contact state is recognized, the threshold value setting unit sets the threshold value to a larger value compared to a case when the contact state is recognized.

  • Patent number: 9109562
    Abstract: A fuel supply device supplies fuel from a fuel tank to an injector by driving a diaphragm pump by use of pressure variation within a crankcase. The diaphragm pump includes: a pump casing; a diaphragm partitioning the interior of the pump casing into a negative pressure chamber and a pump chamber; and a plunger connected to the diaphragm and reciprocatively movable to and from the pump chamber. A pressure receiving area over which the plunger receives, at its end surface in a plunger advancing/retracting direction, pressure from the pump chamber is set smaller than a pressure receiving area over which the diaphragm receives pressure from the negative pressure chamber in the advancing/retracting direction.

  • Publication number: 20100194787
    Abstract: White noise images and white noise-like pattern images are discerned by making use of the fact that the address current is increased when such an image is entered and detecting the address current by an address current detection circuit. When the detected address current exceeds a given value ? and persists for a given period of time, a CPU controls a contrast control circuit to lower the contrast of the video signal, thus reducing the power consumption of an address driver circuit.

  • Patent number: 7159400
    Abstract: When a flow of a working medium stagnates in an expander or evaporator of a Rankine cycle apparatus including a closed working medium circulation circuit, a high pressure exceeding an allowable maximum pressure level of the expander or evaporator is produced within the closed working medium circulation circuit. In such a case, the water-phase working medium is first discharged via relief valves out of the circulation circuit, so that the pressure within the circulation circuit can be lowered. Then, once vapor within the evaporator, having been lowered in temperature and pressure, flows backward within the closed working medium circulation circuit, the vapor is also discharged via the relief valves out of the circulation circuit. In this way, the pressure within the expander or evaporator can be reliably prevented from exceeding the allowable maximum pressure level.
