摘要： PURPOSE:To raise the efficiency of excavating operation by a method in which speed sensors are provided for a tractor and a scraper wheel, a slip amount is calculated from the turning speeds of both the tractor and the scraper wheel, and the height of a ball is automatically adjusted to control the amount of excavation without slip. CONSTITUTION:When a tractor is traveled to drag a scraper, measurement is made for every given periods by sensors 8-12 and measured signals (V)EL, (V)ER, (V)SL, and (V)SR and BH from the sensors 8-12 are put in a controller 13. The measured signals BH are compared with an allowable range to confirm that the height of a ball is within allowable range. If it is out of the allowable range, the height of the ball is moved to a preset one, and the difference between the turning speed of the tractor and the turning speed of the wheel of scraper is calculated in the controller 13. When the difference E is in positive value, a judgement that the traveling system of the tractor is slipped is made and a command is given to correct the position of the ball to given height for a ball drive mechanism 14. The height of the ball is adjusted by the drive mechanism 14, and the load from the ground's surface to the ball can be reduced to eliminate slipping.

摘要： PURPOSE:To enable the correct measurement of distance to a target even with the level fluctuation of reflected waves from the target in a range finder utilizing ultrasonic waves. CONSTITUTION:A receiving part 1 receives reflected waves from a target based on ultrasonic transmit waves sent out synchronously with transmit timing pulses. A comparing part 14 generates a detection signal when the level of an input signal exceeds the threshold value, and a time difference signal generating part 15 generates a signal of time difference between the detection signal and transmit timing pulse. The distance to the target is measured by this time difference. In this case, a low-pass filter 16 is provided to convert the waveform of the input signal into envelope waveform, and this envelope waveform is used as the threshold value. As a result, even if the level of a reflection signal is fluctuated, the detection threshold value is changed accordingly so as to allow the distance to the target to be measured always correctly.

摘要： PURPOSE:To set the angles of a plurality of blades freely in response to the hardness of a floor face, and to improve turning properties, operationability and controllability by supporting the blades by a vertically rockable rocking support section. CONSTITUTION:The base end sections of L-shaped mounting members 14, on which blades 13a-13d are mounted in a rockable manner, are inserted slidably to rotors 10 at the lower ends of inclinable shafts 17 including vertically slidable rotor shafts 16 drooped from a support plate 2. The bent sections of the mounting members 14 are attached pivotally to the bearing sections 15 of the undersides of base plates 18 fixed onto the shafts 17 in the rockable manner. The shafts 17 are supported in the rockable manner in the periphery of an X-axis and in the periphery of a Y-axis through gimbal rings 20 arranged to the upper sections of the base plates 18. According to constitution mentioned above, the angles of each blade 13a-13d can be changed arbitrarily as the degree of freedom of rocking is kept as it is, the blades are rocked in parallel with a concrete floor face at all times regardless of the inclination of the shafts 17, and uniformly distributed load works, thus moving the place of a pressure cone apex in the direction of the center of rotation.

摘要： PURPOSE:To obtain an ultrasonic distance measuring apparatus, which is mounted on a moving body, transmits and receives ultrasonic waves to and from a target from the moving body to the direction of the side surface thereof and can obtain the central position of the target based on the sequentially measured distance data to the target. CONSTITUTION:Ultrasonic-wave transmitting means 1 and 3 transmit ultrasonic waves in the direction perpendicular to the moving direction of a moving body. Pairs of ultrasonic-wave receiving means 2A and 4A and 2B and 4B individually receive the reflected waves of the transmitted ultrasonic wave at positions on both sides, which are separated at an equal distance in the moving direction of the moving body and the opposite direction of the moving direction from the position of the transmission of the ultrasonic waves. A pair of distance measuring parts 6A and 6B individually measure the distance to the target based on the time between the transmitting time of the ultrasonic wave and the receiving time of a pair of the ultrasonic waves. An arithmetic processing part 7 computes the central position of the target based on the difference data of a pair of the measured distance data. These parts are provided.

摘要： PURPOSE:To estimate the residual capacity of storage battery by stopping the charge making the discharging rate constant at the checking time and checking a specific terminal voltage inherent in the storage battery. CONSTITUTION:By an operation of switch 5 for the checking at the time when the storage battery 1 is being charged by a power supply 4 for charging through a charge circuit 3, a resistor 6 for correction is connected in parallel to a load 2 and a voltage generated in the resistor 6 is applied to a control circuit 7, and the supply of charging voltage to the storage battery 1 from the circuit 3 is interrupted by the circuit 7. At this time, a discharge current becomes to a specified value by the resistor 6 for correction, and the interference of charge voltage to the terminal voltage of the storage battery is isolated, then the specific terminal voltage at the specified loading rate is generated in the storage battery 1 and applied to display circuits 8, 9. When the terminal voltage of the storage battery 1 reaches a discharge finish voltage settled in the circuit 8, a voltage detecting circuit 11 is exerted to turn off a pilot lamp 12, thereby a requirement to start the charge is indicated. When the voltage corresponding to the fully charged state is set to the circuit 9, the enough residual capacity can be indicated by the lighting of pilot lamp 12 of the circuit 9.
