At the same time, a signal A in a high level holds a T30 to be on, the condition of a constant current source 38 is fulfilled, and a T32 is held to be off. When the signal B is turned into a high level, the T36 is turned on, the T34 is turned off, a voltage C at the collectors of the T32 and 34 is turned into a high level, and an output D from an integrator is decreased according as a capacitor 48 is charged.  When the signals B and A are turned into a low level, the T34 and 32 are turned on, currents are allowed to run through the resistance 42, the voltage C is decreased to the minimum value, a capacitor 48 is discharged, and the output D is increased to the previous level. Thus, the speed of a circuit can be improved.

The frost heaving force of the active layer 6 is absorbed by the covering part 11 and the fluid substance 17 and prevented from its transmission to the pile 1. When the active layer 6 is thawed and settled in summer season, the covering part 11 is also lowered and restored to its original state.

Abstract: PURPOSE:To measure the bearing distribution in the axial direction of a piston continuously and accurately by allowing a bearing detector to detect variation in bearing between internal surfaces of the ring groove of a piston ring which rotates together as a cylinder is rotated slowly. CONSTITUTION:When a combined oil ring 8 rotates together with the cylinder 24 while a thin bearing measurement part 22 formed on a piston 13 is fixed, side rails 10 and 11 of the combined oil ring 6 differ in pressing force to axial internal surfaces 20 and 21 of the piston 13 in the piston ring groove 19 in a peripheral direction, so the bearing measurement part 22 is displaced in the axial direction of the piston 19. This displacement is detected by the bearing detector 30 in real-time and its bearing detected value is outputted to a load cell 34. The load cell 34 converts the bearing detected value into a voltage signal, etc., and outputs it to a bearing distribution display system 42 successively. The bearing distribution display system 42 amplifiers the signal sent from the load cell 34 by an amplifier 43 and displays it on a display part 44. Thus, the bearing distribution of the combined oil ring is measured continuously and securely.
