An ultrasonic generator has a speaker element having a first resonance frequency and a speaker element having a second resonance frequency. The first resonance frequency and the second resonance frequency are adjacent resonance frequencies in the speaker. The distance between the elements is set so that the sound from the first speaker element and the sound from the second speaker element have a predetermined relationship at a target position. The target position is two or more positions on the object located in the target space. A predetermined relationship is a relationship in which a sound from the first speaker element and a sound from the second speaker element strengthen each other at an intermediate frequency between the first resonance frequency and the second resonance frequency.

A vehicle speed limiter system installed on a vehicle includes a detection unit to detect a speed limit value of a road while the vehicle is traveling; a setting unit to set the speed limit value; a limiter unit to limit the vehicle speed, based on the speed limit value; an obtainment unit to obtain a stepping amount on an accelerator pedal; a calculation unit to calculate a parameter depending on the stepping amount in a state where the vehicle speed is being limited by the limiter unit; and a display unit to display information based on the parameter, in a case where a speed limit value newly detected by the detection unit is greater than the speed limit value previously set by the setting unit, before the setting unit sets the speed limit value newly detected.

Vehicle speed limiter system

A load sensor includes: a substrate; a rib on the substrate; and two vertical transistors. Each vertical transistor includes: a gate electrode, a gate insulation film, and a semiconductor thin film on the side surface of the rib; a bottom electrode layer on a bottom of the substrate, on which the rib is not arranged, with contacting the semiconductor thin film; and a top electrode layer on a top of the rib with contacting the semiconductor thin film. Each vertical transistor flows current between the bottom electrode layer and the top electrode layer when a channel region is provided in the semiconductor thin film. Each straight line along normal line directions of the channel regions in the vertical transistors is arranged on a different side surface of the rib from each other, and has a predetermined angle between the straight lines.

A vehicle's accelerator pedal depression amount is detected; a speed limit of a road on which the vehicle is traveling is determined; a start of a lane change is estimated; an upper-limit speed is determined each time when the speed limit changes; and the travelling speed is controlled to not exceed the upper-limit speed even if the accelerator pedal depression amount increases to cause the speed of the vehicle to exceed the upper-limit speed. The speed of the vehicle is controlled, until a predetermined timing, to not exceed the upper-limit speed determined before the start of a lane change is estimated, if (i) the start of a lane change is estimated, and (ii) a reduction in the speed limit is determined. After the predetermined timing, the speed of the vehicle is controlled to not exceed the currently determined upper-limit speed.

Vehicle speed control apparatus and vehicle speed limiting apparatus

A control system for a vehicle includes an imaging device; a co-ECU to limit the travel speed of the vehicle; and an ECU to set the speed limit, that recognizes the speed limit value on a road while traveling, and sets the recognized speed limit value in the co-ECU. If the elapsed time since the speed limit value has been set reaches a predetermined time, the ECU estimates the speed limit value on the road while traveling, and if receiving a switch command, switches the speed limit value set in the co-ECU to the estimated speed limit value so as to avoid limiting the vehicle speed by a speed limit value that is different from the actual speed limit value on the road.

Control system for vehicle

A vehicle control system includes a limiter device, and a setting device to set an upper speed limit on the limiter device, based on speed limit values extracted from image information. The setting device includes a derivation unit to derive a condition to raise display priority for each speed limit value; an obtainment unit to obtain determination information for determining whether the condition is satisfied; a calculation unit to raise the display priority of the speed limit value that corresponds to the condition determined satisfied with the determination information, among the speed limit values extracted from the image information; a display control unit to display the speed limit values in descending order of the display priority; and a setting unit configured to set the upper speed limit on the limiter device, based on one of the displayed speed limit values, selected by an occupant of the vehicle.

Vehicle control system

A vehicle speed limiting apparatus includes an opening detection unit to detect an opening of an accelerator pedal of the vehicle; an estimation unit to estimate whether the vehicle starts a lane change; and an ECU to implement an upper-limit setting unit to set an upper-limit speed of the vehicle, a vehicle speed control unit to control the traveling speed so as not to exceed the upper-limit speed even when the opening of the accelerator pedal becomes great enough to make the traveling speed exceed the upper-limit speed, and a permissible speed setting unit to set a permissible speed higher than the upper-limit speed. When the estimation unit estimates that the vehicle starts the lane change, the vehicle speed control unit permits the traveling speed to exceed the upper-limit speed, and controls the traveling speed so as not to exceed the permissible speed.

A check valve includes a valve seat portion and a reed valve element and is received in a receiving hole of an intermediate pressure refrigerant supply passage that is placed adjacent to a flow inlet of an injection port, through which a refrigerant of an intermediate pressure is injected into a compression chamber. A center of the flow inlet of the injection port is offset from a central axis of a valve seat passage formed in the valve seat portion.

Compressor

A load sensor is constituted by a rib and a vertical transistor including an organic semiconductor film, and a load measurement can be executed based on a change of a gap between a drain electrode and a source electrode which is a channel length of the vertical transistor. Therefore, a change of a current Ids is in a linear relationship to a load applied to the load sensor.

A multiprocessor system is disclosed. The multiprocessor system includes plural processor cores to which control to be performed is allocated. The multiprocessor system includes a monitoring processor which detects an abnormal operation that has occurred in a specific processor core to which control having a higher priority order than control to be allocated to processor cores other than the specific processor core is allocated. When the monitoring processor detects the abnormal operation in the specific processor core, the monitoring processor allocates the control having the higher priority order to one of the processor cores other than the specific processor core.
