Filed: 1993-12-22
Abstract: PURPOSE:To improve the execution efficiency by setting the reference outbreak quantity, detecting the outbreak quantities, bending a leading pipe in the prescribed direction in reference to the compared result with the reference outbreak quantity, or bending a head section in the opposite direction to the prescribed direction, then bending it. CONSTITUTION:Outbreak quantities L5, L6 which are gaps between the outer diameter of a leading pipe 10 and a tunnel inner face 7 generated by an outbreak cutter 12 protruded from the outer diameter of the leading pipe 10 are measured by four outbreak quantity sensors 31 respectively, and the average value of four quantities is grasped as the outbreak quantity L. When outbreak quantity L > reference outbreak quantity Lo, a rocking cylinder 21 is rocked, the direction of a head section 1 is bent in the opposite direction by about 180 deg. to the correction direction, then the tip outer periphery section 2a of a rock section 2 is located on the correction direction side of the tunnel inner face 7. The rocking cylinder 21 is rocked while the head section 1 is rotated, the head section l is bent in the correction direction, and the head section 1 is propelled in the correction direction while excavating the ground. The direction can be correctly changed.

Title: Gear change control unit of automatic transmission for vehicle
Inventor: OISHI TOSHIYA
IPC: F16H61/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the multiple gear change by preventing the gear change to a B shift stage, and substantially performing A→C gear change, by performing the gear change from the B shift stage to a C shift stage while limiting the oil pressure of a frictional engagement unit by less than a prescribed value, when the command for the gear change to the C shift stage is output during the gear change from an A shift stage to the B shift stage. SOLUTION: When a 1→2 gear change (A-B gear change) command is output, whether the command of gear change to the third shift stage (C speed) is output or not, is judged in ECU for speed change 78, so that the exciting condition of the electromagnetic valves S1-S3 is switched to obtain the second shift stage, when the judgement is NO, and a corresponding brake B3 is engaged by controlling the oil pressure of a linear solenoid value SLU. On the other hand, when the judgement is YES, the ordinary 2→3 gear change is executed when an accelerating pedal 50 is not stopped on, but when the accelerating pedal 50 is stopped on, the oil pressure of the brake B3 is limited to be less than the comparatively low certain oil pressure free from the engagement of the brake B3, and the 2→3 gear change is executed.
