The steering control device includes an automatic steering controller that generates an automatic steering control amount and a manual steering controller that generates a manual steering control amount, and selects either one of an automatic steering mode and a manual steering mode to control an electric motor. When steering torque exceeds a predetermined value during the control in the automatic steering mode, the manual steering controller generates a manual steering control amount change based on the change in the manual operation amount with reference to the time of exceeding, generates the manual steering control amount based on the steering torque, controls the electric motor based on a control amount obtained by adding the manual steering control amount change to the automatic steering control amount at the time of exceeding, and then controls the electric motor in the manual steering mode.

In order to detach substances stably from an inspection object, an adhering substance collecting device includes: ejection openings configured to eject gas; a housing on which the ejection openings are provided; and supporting portions which are installed on a surface of the housing on which the ejection openings are provided, and have a prescribed height. The supporting portions include protruded portions formed on the housing. The supporting portions each have a cuboid shape, and are installed such that a distance therebetween becomes smaller toward a direction of a recovery opening that is configured to collect substances having been detached from an inspection object, from the gas.

Adhering substance collecting device and inspection system

In order to suppress malfunctions even when using a reagent (chemical for reagent) corresponding to a hazardous substance, the present invention has an analyzing unit in which a chemical for reagent, having added thereto an indicator that is different from a hazardous material that is a detection target, is used to calibrate on the basis of the detection target included in the chemical for reagent, and which performs mass spectrometry. When a peak corresponding to the indicator is not included and a peak corresponding to the detection target material is included in the spectrum that is the analysis result of the analyzing unit, the detection target is determined to be included.

Chemical for test used in hazardous substance sensing device, hazardous substance sensing device, and hazardous substance sensing method

A steering device is provided to perform a safe transition from an automatic driving mode to a manual driving mode when necessary. When it is determined necessary to transition from the automatic driving mode to the manual driving mode during the automatic driving mode, a transition period before an end time point of the automatic driving mode is set, a driving operation reliability indicative of whether or not it is possible to perform the transition is determined, and the transition when it is determined that it is possible to perform the transition to the manual driving mode during the automatic driving mode. Consequently, the transition can be controlled so that transition is not performed instantly, such as, for example, in a case where a driver is not driving during the automatic driving mode and is not accustomed to manual driving.

Provided is a radiation monitor, including: a radiation detection unit which includes a radiation detection element, the radiation detection element emitting light of a predetermined light emission wavelength; a light emission unit which emits light of a wavelength different from the light emission wavelength; a wavelength selection unit which passes the light of the light emission wavelength, and is set to a first mode to block the light from the light emission unit; an optical transmission line which transmits the light; a light detection unit which converts the light passing through the wavelength selection unit into an electric pulse; and a control unit which measures a count rate of the electric pulse, and determines whether at least the light emission unit is degraded on the basis of the count rate and a light intensity of the light emission unit.

Radiation monitor and method of analyzing radiation monitor

Provided is a steering device which allows continued safe travel in the event of a fault during automatic steering control. The steering device is equipped with an electric drive device composed of a plurality of systems of electric motors and has an assist control function for assisting a driver in steering and an automatic steering control function for automatically controlling the steering angle of steered wheels on the basis of a steering angle instruction value. In the event a fault occurs in one of the electric motor systems of the electric drive device during control under automatic operation control, a controller in the steering device maintains automatic operation control Susing the electric motor of a normally operating system not suffering from a fault, and then, upon shifting to assist control S, the controller sets the output limit value of the electric motor to a fault-time output limit value, which is less than a normal-time output limit value set when all electric motor systems are operating normally.

It is an object of the present invention to provide a power steering apparatus control device in which it is possible to suppress generation of the canceling of the automatic steering unintended by the driver. The present invention provides a control device controlling the operation of a power steering apparatus in which there is selected either an assist control () in which a steering force is assisted based on a steering torque input through the operation of a steering wheel or an automatic steering control () in which a steering angle of a turning wheel is controlled based on a steering angle command value. When, in the state in which the automatic steering control () is selected, the steering torque exceeds a predetermined threshold value, the automatic steering control () is canceled and the assist control () is selected. There is set a steering angle velocity command value in accordance with an increase amount of the steering torque due to the turning based on the automatic steering control (), whereby there is performed a canceling suppression control in which canceling of the automatic steering control () is suppressed.
