Abstract: PURPOSE:To speedily restore a servo gain to a normal gain by supplying a maximum operating voltage to a driving circuit when a defect signal detection circuit detects any defect. CONSTITUTION:When a defect signal detector 35 detects any defect signal, a transistor 36 is turned on and a control signal larger than the maximum control signal to be obtained from a maximum control signal detection circuit 15 is generated and impressed to a time constant circuit 25.

Inventor: SUGIYAMA HIROMASA
IPC: E01C11/10
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide the construction structure of a boundary block between a pedestrian way and a roadway, which does not clack and peel off even though a vehicle runs thereon. SOLUTION: A construction structure is composed of boundary block 1 between a pedestrian way and a roadway, each incorporating apron, and laid on a base layer 4 along the road, and a joint member 3 set in a joint part 2 between the block 1. The joint part 2 is opened upward, and the joint member 3 is made of an elastic material. With this arrangement, even though a vehicle runs on the apron part 1b so that the blocks 1 are vibrated by variable load exerted from the vehicle, the vibration is attenuated since they are joined to each other through the joint member 3. Thus, no stress concentration occurs around the joint part 2 of the block 1.  Even though the condition of contact between the blocks 1 and the base layer 4 is worse so that the blocks rattle with respect to the base layer 4, the rattling is similarly attenuated, thereby it is possible to prevent stress concentration around the joint part 2 between the blocks 1.
