An insulation detecting device having a capacitor and a DC power source, insulated from a ground potential part. A voltage detecting unit, detects a voltage across the capacitor. A first switching unit connects the capacitor to the DC power source in series for a first preset time shorter than a time taken for completely charging the capacitor. A second switching unit connects the capacitor between a positive terminal of the DC power source and the ground potential part in series for a second preset time. A third switching unit connects the capacitor between a negative terminal of the DC power source and the ground potential part in series for the second preset time. A fourth switching unit connects the voltage detecting unit to the capacitor after the first to third switching units are turned off. A computing unit estimates a voltage across the power source.

An apparatus for controlling the traveling of a mower comprising means for detecting the conveying state of cut grass in a shooter, and means for decelerating the traveling speed of the working machine while continuing the mowing work by the cutter and the feeding of an air flow to the shooter if the conveying state is more degraded than a jam prevention judgment criterion on the basis of the detection signal of the conveying state detector means. The conveying state of grass in the shooter is detected based on the density or amount of cut grass passing through the shooter per unit time, and the mower is decelerated while maintaining the rotation of the cutter blade for mowing and/or the feeding of the air flow into the shooter if the density exceeds a predetermined threshold value. A threshold value can be adjusted according to the condition of the grass to be cut; for example, high, degree of overgrowth, degree of dry or wet of the grass.

A transmission type light sensor is disposed in the vicinity of the exit of a shooter, which has the exit thereof positioned above a grass-bag opening, and the fullness of the grass-bag is detected when the light blocking state of the sensor continues longer than a predetermined time. A light emitting portion and a light receiving portion of the light sensor are positioned opposite to each other so that their optical axes are in coincidence, and they are firmly attached to both ends of a light sensor mounting member. The light sensor consists of a light sensor main body which is placed at one side of a cover, and a retroreflective board placed at the side of the cover opposite to the light sensor main body for reflecting incident light from the light emitting portion in the direction of incidence.

A valve assembling and checking method includes the steps of: using air pressure from a nozzle 50 to press a spring 4 against the inner wall of a valve hole 2 to hold the same in a vertical position; moving the spool 3 immediately above the valve hole and allowing the spool to fall from a spool holding means 30, and repeating clamping and unclamping actions to adjust the location of the spool so that the spool is correctly received in the valve hole 2.

A cant angle sensor assembly, includes a pendulum pivoted on a supporting system adapted to be mounted on an object whose cant angle is to be sensed, for swinging movement in a direction of tilt of the object, a movable electrode provided on the pendulum and having a first and a second movable electrode plate, and a first stationary electrode plate fixedly mounted on the supporting system in an opposed relation to one of the first and second movable electrode plates of the movable electrode at a predetermined gap, with an area of the first stationary electrode plate opposed to one of the first and second movable electrode plates being invariable despite vibration of the pendulum. Further, second and third stationary electrode plates are fixedly mounted on the supporting system in an opposed relation to the other of the first and second movable electrode plates of the movable electrode plate at a given gap, so that with the swinging movement of the pendulum, areas of the second and third stationary electrode plates opposed to the other of the first and second movable electrode plates are increased and decreased in a manner contrary to each other.
