摘要： PURPOSE:To obtain a measuring method which facilitates the measurement of delivery speed and length of a cable along with limited measuring errors. CONSTITUTION:In an apparatus which delivers a cable from a cable drum 6, the distance to a rotating shaft of the cable drum from a specified fixed point between flanges of the cable drum 6 is represented by L0 the distance to the outermost circumferential surface of the cable wound on the drum from the fixed point is shown by L(t), and the number of revolutions of the drum by n(t) and the time by t. The rotational speed of the drum is determined by V(t)={L0=Lt}X2pi n(t) and the delivery length of the cable by LT(t)=integral v(t)dt.

摘要： PURPOSE:To reduce the height dimension of a device by installing a belt driving part and a motor part in series on both the sides of a body gear part. CONSTITUTION:A cable sending-out device is equipped with a belt driving part 29 for revolution-driving a pair of belts 21 which nip and pull a cable, and a body gear part 26 which transmits the driving power of a motor part 30 to the belt driving part 20. The belt driving part 20 and the motor part 30 are installed in series on the body gear part 26. Accordingly, the height dimension of the device can be reduced. Accordingly, when the cable sending-out device is used in a tunnel, etc., the cable can be laid with high workability without shifting the cable.

摘要： PURPOSE:To make unnecessary the support of the winding end part of a cable by coupling the one end of a supporting rope to the area of a cable near the end part thereof, then winding the supporting rope for several turns to the drum body and then supporting the other end of the supporting rope with a braking apparatus. CONSTITUTION:A drum 1 winding a cable 3 is supported on a base 15 with an supporting arm 16 and the cable 3 is guided by an extension roller 4 for supply into a manhole 5. The one end of a supporting rope 25 is coupled with area of the cable 3 near the winding end. The supporting rope 25 is wound for several turns around the body 1A of drum 1, while the other end of the supporting rope 25 is wound for the supporting purpose around a braking apparatus 26 consisting of a winding part 26A and a braking motor 26B. Thereby, it is now unnecessary to support the winding end of the cable 3 and provide a flexible tube in the vertical wall of the manhole and thereby the efficiency of cable laying work can be improved.

摘要： PURPOSE:To detect a slip so as to stop a travel when a drive controller disapears out of the visible field of an operator and a slip develops on a drive wheel during travelling by comparing the output of a drive wheel tachogeneraor (TG) with that of a follower wheel TG so as to control the drive device. CONSTITUTION:The drive TG 7 detecting the rotational speed of the drive wheel 5 and the follower wheel TG 8 detecting the rotational speed of the follower wheel 4 generate voltages in proportion to their rotational speeds, and output them to a comparator 9. It compares these voltages, and transmits the ratio of the voltages to a controller 10. When the ratio of the voltages lies within the range of a preset value, the controller transmits a travel continuing instruction to the drive device 6. On the other hand, when the slip develops on the drive wheel 5 and the ratio of the voltages exceeds the set value, the controller 10 sends the travel stop instruction to the drive device 6 and stops the travel of an in-pit carrier.

摘要： PURPOSE:To realize a highly accurate measuring method of optical loss, by measuring the amount of optical loss of a measuring member at least keeping a light source at a fixed temperature as immersed into a liquid to remove effects due to temperature changes. CONSTITUTION:Light with a long wavelength is outputted from a light source 1 is made enter a measuring member 3 intended to measure an optical loss through a fiber cord 2. Light transmitted through the measuring member 3 is received with a light receiving sensor 4 composed of a photodiode and a light output thereof is converted into an electric signal to be displayed as optical power after passed through a metal cord 5 to be amplified with a power meter 6. Then, the light source 1 is immersed into a insulated container 7 filled with a liquid 9 and a constant temperature electron circulator 8 is operated to keep the liquid 9 at a specified fixed temperature. This can minimize variations in the received optical power with temperature changes thereby enabling the measurement of the optical loss of the measuring member at a very high accuracy.

摘要： PURPOSE:To simply measure the absolute position and azimuth angle of an excavation head only by measuring induced voltage, by calculating the angle of rotation of a magnetic field element generating max. induced voltage by the magnetic field from a magnetic field generating element. CONSTITUTION:A transmitter 4 and a transmitting coil 2 are arranged on the ground at both sides of a tunnel T to be excavated and a pit side transmitted-receiver 8 and a personal computer 9 are further arranged so as to be connected to each other. When a receiving coil 3 is rotated to two directions crossing vertically by a receiving coil driving part, the voltage inducted in the receiving coil 3 changes so as to follow the rotational operation of said coil 3. In this case, the induced voltage changes in a sine wave form according to the change in the angle of rotation of the receiving coil 3 and, when the angle of rotation of the receiving coil is 80.4 deg., the induced voltage becomes max. Therefore, a characteristic drawing of the angle of rotation of the receiving coil showing max. induced voltage and the horizontal distance R and vertical distance Z between the transmitting coil and the receiving coil is preliminarily formed and the receiving coil in an excavation head is rotated on the plane of an advance direction and the plane vertical thereto to induce voltage. Only by measuring the induced voltage at this time, the position and azimuth angle of the excavation head can be simply measured.
