IPC: G11B20/18
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To set mute conditions flexibly and to prevent a noise generated at a mode changing point. SOLUTION: Assuming that one frame of delay is produced when a reproducing discrimination signal is transmitted from a demultiplexer 11 to a control part 14, and one frame of delay is produced when an operation mode instruction is transmitted from the control part 14 to a decoder 12 and coincidence detecting circuit 15, the timing of operation instruction mode is delayed by two frames from the reproducing identifying signal. The coincidence detecting circuit 15 compares the reproducing discrimination signal and the operation mode instruction. For that purpose, in a period that states of the reproducing discrimination signal and the operation mode instruction are different, a second mute control signal is activated to make it possible to prevent noise generated in a mute part 13.

Abstract: PURPOSE:To simplify the measurement of deflection between the position of an excavator and the programmed line of excavation as well as the measurement of distance between the excavator position and a reference point, by forming a tracking device with a light emitting part set at the reference position and a photodetecting part set at the excavator. CONSTITUTION:A screen B5 is shifted to the right or left together with a mobile stage B2 by means of a screw type feed mechanism B3 so that a light beam 9 for collimation radiated from a radiator A6 of a light emitting part A set at a reference point irradiates the vertical center line of the screen B5 of a receiving part B. In this case, the shift degree Xm from the center of this mechanism is read by a pulse motor B1. A control unit A9 calculates a distance Lx by measuring the time during which a distance measuring beam 10 is emitted from a range finder A7 and then returns to the finder A7 after the reflection by a corner cube B4 of the part B. This distance Lx is fed to a control unit B8 of the part B via a communication device A8, the beam 10 for communication and a communication device B4. The unit B8 obtains the deflection dx between the position of an excavator and the programmed line of excavation from the Xm and Lx.
