A work machine includes a work unit, and an adjustment unit configured to adjust a working height of the work unit. The adjustment unit includes a lifting mechanism configured to lift and lower the work unit; a torque limiter configured to interrupt transmission of a driving force of a motor to the lifting mechanism when the work unit reaches an upper and lower limit positions; and a sensor. The torque limiter includes a transmission member provided to be displaceable between a transmission position at which the driving force is transmitted to the lifting mechanism and a non-transmission position at which the driving force is not transmitted to the lifting mechanism, and an elastic member configured to bias the transmission member to the transmission position. The sensor detects displacement of the transmission member.

An autonomous work system controls an autonomous work machine that detects a magnetic field of an area signal generated by energization to an area wire disposed on an outer periphery of a work area, specifies a boundary of the work area based on the magnetic field, and works autonomously in the work area. The autonomous work system comprises: a storage unit configured to store position information of a plurality of the work areas; a setting unit configured to set, based on the position information, different energization modes; and an energization unit configured to energize, based on the energization modes, the area wires disposed on the respective outer peripheries of the plurality of adjacent work areas.

Autonomous work system

A working machine is provided which can suppress the adhesion of rain water, snow, and melting snow to an electrical connecting portion between a battery containing portion side and a battery side. An electrically driven snowplow as a working machine includes a battery pack incorporating a battery, a battery containing portion disposed so as to allow the battery pack to be inserted and removed in a direction inclined from a vertical direction, and an electrode portion configured to be connected with an output terminal of a battery disposed on an upper surface of the battery containing portion.

An unmanned operation vehicle includes a housing, a wheel provided in the housing, and an operation unit provided under the housing. The housing includes a plurality of cameras configured to capture an image of an outside of the unmanned operation vehicle. The plurality of cameras are arranged substantially at a center of an upper surface of the housing in a plan view. The housing may include a single camera unit including the plurality of cameras.

Unmanned operation vehicle

An unmanned operation vehicle includes a housing, a wheel provided in the housing, and an operation unit provided under the housing. The housing includes a camera unit, a stop switch configured to stop driving of the wheel and the operation unit when actuated, and a stop switch actuating member configured to actuate the stop switch. The camera unit is arranged substantially at a center of an upper surface of the housing in a plan view, and the stop switch actuating member is arranged immediately above an upper surface of the camera unit.

A marking device includes a light-emitting unit configured to emit light, a housing configured to accommodate the light-emitting unit, and a support configured to support the housing. The housing can include a transmitting portion configured to transmit the light from the light-emitting unit through a circumferential portion of the housing, and a roof covering the light-emitting unit accommodated in the housing. The housing can include a side wall formed between every two adjacent windows of the plurality of windows.

An automatic operation vehicle that automatically performs an operation in an operation area is provided. A survey unit acquires the position information of the marker using a first angle between the moving direction and a direction to the marker from a first point through which the vehicle passes during the movement in a constant moving direction, a second angle between the moving direction and a direction to the marker from a second different point through which the vehicle passes during the movement in the moving direction, and a distance between the first point and the second point. The survey unit determines the first point and/or the second point during the movement of the vehicle in the moving direction such that the angle difference between the first angle and the second angle becomes close to 90&#xb0;.

Automatic operation vehicle

An automatic operation vehicle that automatically performs an operation in an operation area is provided. The vehicle includes an image analysis unit configured to extract a marker included in an image captured by a camera provided on the automatic operation vehicle. If a situation in which the marker that was extracted from the image captured by the camera cannot be extracted by the image analysis unit from the image captured by the camera has occurred during a movement of the automatic operation vehicle in a constant direction. The image analysis unit determines whether the marker extracted before an occurrence of the situation and the marker extracted after an elimination of the situation are the same marker.

An automatic operation vehicle that automatically performs an operation in an operation area is provided. The vehicle includes a moving direction determination unit configured to determine a moving direction of the vehicle, an image analysis unit configured to extract a marker included in an image captured by a camera provided on the vehicle, and a survey unit configured to acquire, by triangulation, position information of the marker extracted by the image analysis unit. When the survey unit starts acquiring the position information of the marker, the moving direction determination unit determines, as the moving direction, a direction in which the vehicle does not come into contact with the marker, and an angle difference with respect to a direction from a current position of the vehicle to the marker is smaller than 90&#xb0;.

Electrolyzed water producing method and apparatus are provided which are capable of producing electrolyzed water having a desired property irrespective of the quality of raw water supplied and the like while allowing the size and weight of the apparatus and the cost to be reduced by limiting the capacity of an electrolysis power source. The electrolyzed water producing method includes: circulating an aqueous electrolyte solution to a first electrolytic chamber of a pair of electrolytic chambers opposed to each other across an intervening ion permeable diaphragm while supplying raw water to the second electrolytic chamber; and applying a predetermined voltage to a pair of electrodes disposed in the respective electrolytic chambers with the diaphragm intervening there between, to electrolyze the raw water and the aqueous electrolyte solution, thereby producing electrolyzed water in the second electrolytic chamber.

Electrolyzed water producing method and apparatus

An indicatorhaving LEDsis mounted on a panelwhich is provided at the center of a steering handlefor monitoring the winkers. The indicatorindicates the battery charge amount with the lit up LEDsand also the right or left turn of the vehicle when a winker switchis turned on for indicating the corresponding steering direction. For right turns, the LEDsare lit up incrementally in a sequence from the left to the right. As the LEDsall have been lit up, they are temporarily turned off and their action in the incremental sequence is then repeated. For left turns, the LEDsare lit up incrementally in order from the right. As the LEDsall have been lit up, they are temporarily turned off and their incremental action from the right is then repeated.
