A snowplow having a snow removal mechanism, the snowplow comprises: an obtainment unit configured to obtain topography information prior to snow accumulation; and a projection unit configured to, based on the topography information prior to snow accumulation obtained b the obtainment unit, project an image indicating the topography information prior to snow accumulation on a surface of accumulated snow that is to be removed by the snow removal mechanism.

Snowplow, projection method for snowplow, storage medium, and projection system

A very small and economical acceleration sensor which can detect acting acceleration with high sensitivity and high accuracy by precisely processing a semiconductor substrate and the like by using the photoengraving technique in a semiconductor manufacturing process to accurately form the elements themselves such as a sensor case, a cavity, a heater, a temperature-sensing resistor element, and a heat-type temperature-sensing resistor element, and the relative placement of each element. One embodiment of the acceleration sensor can detect acceleration acting from any of the three-dimensional directions.

Acceleration sensor with temperature resistor elements

A hybrid sensor which is comprised of an acceleration sensor for detecting acceleration based on a temperature distribution of a predetermined gas hermetically enclosed within a fluid-tight space, and an angular velocity sensor for detecting angular velocity based on a deviation of a flow of a predetermined gas. The acceleration sensor and the angular velocity sensor are formed in one piece by the use of semiconductor processing technology in such a manner that the acceleration sensor and the angular velocity sensor are formed on a plurality of semiconductor substrates, and then the plurality of semiconductor substrates are superposed one upon another and united into a laminate.

Hybrid sensor

Acceleration sensor

A gas rate sensor comprising a sensor body, a pump control device and a resistive bridge circuit. Semiconductor substrates are accurately photoengraved by semiconductor fabrication techniques to integrally form a pair of heat-generating and heat-sensitive resistive elements, a gas passageway, a pump casing, and other components in the sensor body. The pump control device controls a piezoelectric pump for creating a gas flow. The resistive bridge circuit is composed of the aforementioned resistive elements and a pair of reference resistors. The pump control device sets the gas flow rate to a given value to detect only the angular velocity acting in the direction of yaw. The angular velocity can be detected accurately with high sensitivity.

Gas rate sensor for detecting horizontal angular velocity

An angular velocity sensor of the type wherein a flow of gas forced by a pump into a gas path in the sensor body through a nozzle hole and directed toward a pair of thermosensitive resistance elements provided in the gas path is deflected by the action of an angular velocity and the deflection of the gas flow is sensed by the thermosensitive resistance elements, and which is further provided with a thermostatically-controlled gas path which is heated in order to maintain the gas flow at a constant temperature to avoid the effect of ambient temperature variations. The sensor also is provided with a gas path for absorbing pulsations of the gas flow caused by pumping operations.
