摘要: An engine-driven brush cutter (100) equipped with a safety device (42) that includes an acceleration sensor unit (24) attached to a drive unit (4) in an aslant orientation such that a detection axis (DA) of the sensor unit (24) inclines by an angle (θ1) relative to the up-and-down direction (V) of the brush cutter (100). This inclined orientation of the detection axis (DA) contributes to lowering the sensitivity of the sensor unit (24) to engine vibration to which the safety device should not be sensitive so much.

摘要: In a brush cutter (100), when it is determined based on acceleration information including frequency components, supplied from an acceleration sensor (24) included in the brush cutter (100) that the acceleration shows a peak in a range of frequencies lower than 100 Hz, the flow moves to step S5 to amplify the acceleration peak. In next step S6, the acceleration peak is compared with a threshold. When the result of comparison shows that the acceleration peak is higher than the threshold, the flow moves to step S7 to produce a safety signal. The safety signal is output from the controller (26) to a high voltage generation circuit (30) to stop generation of a high voltage in the high voltage generating circuit (30). In this manner, the acceleration sensor (24) is used to detect any unexpected, sudden danger, while diminishing influence of the acceleration caused by vibration inherent to the own nature of the work apparatus, its intended regular operation and its posture change in regular operation.

摘要: A fresh water generator includes a primary pump for pumping up water to be treated, a secondary pump for pressure sending, and a filtering device for purifying the water to be treated which is sent from the secondary pump by pressure. The fresh water generator further includes interlocking devices for interlocking clutch means of transmission devices and an operation lever of a three-way valve. The operation lever can be switched to one position from the other position and vice versa. The one position is a position in which the clutch means are actuated, thereby transmitting drive power from an internal combustion engine to the primary pump. The other position is a position in which the clutch means are relaxed, thereby blocking transmission of the drive power to the primary pump.
