Title: Excavator for underground wall
Inventor: ABE SUKEZOU
IPC: E02F5/02
Filed: 1979-08-22
Abstract: PURPOSE: To efficiently excavate rocks and pebbles and construct an enclosure wall for the underground tank by giving an oscillating turn to the roller cutter mounted opposed at the tip of the arm.  
     CONSTITUTION: A casing having a rectangular cross section is hung down and a roller cutter 7 is driven to turn for excavation. If the excavation operation to the full stroke of adjusting jack 13 was completed, the stroke is minimized and the excavator is lowered by a crane to an attainable bottom. After this procedure, the same process is repeated. The roller cutter 7 is oscillated to excavate its way through. The cutter teeth 8 are intermeshed between the both rollers, so that pebbles are crushed into fine size. In addition, due to the oscillation of the cutter 7, even the hard core of the rock formation can be crushed and excavated evenly, thus improving an excavation efficiently. During the excavation, gripper jack 10 is caused to slide with its gripper 9 pressed against a pit face 14. Crushed rock and mud are discharged to the outside by the excavated dirt suction pipe 11 through a rubber hose 12.

Abstract: PURPOSE:To prevent previously the spread of injury due to exfoliated film powder, by inhibiting a shift of a head to a data zone if a contact start-stop zone is injured by the rub with the head of a magnetic disk device is started. CONSTITUTION:A signal is previously recorded to a contact start-stop zone 1 with a fixed frequency. A head 2 is set still on a disk 6 before the disk 6 revolutes. Then the disk 6 is revolved, and the number of revolutions reaches the prescribed value. The output of the floated head 2 is detected via an amplifier 3 and a waveform processing circuit 4. A circuit 5 checks whether the output of the above-mentioned detection is higher than the prescirbed level. When the detection output is larger than the prescribed value, a control circuit 8 drives an actuator to move the head 2 up to a desired position on a data zone 7. While the circuit 8 decides that the injury of the zone 1 exceeds an allowable range when the detection output is less than the prescribed value. Then it is inhibited that the head 2 is shifted to a position on the zone 7 by the actuator.
