Title: Relieving method of earth pressure acting on culvert
Inventor: NAKAGAWA YOSHIHIRO
IPC: E03F3/04
Filed: 1989-05-25
Abstract: PURPOSE:To contract a joint interval if earth pressure is increased as well as to relieve the earth pressure acting on a culvert by installing a joint, filling up a joint filler smaller in rigidity than material constitution a wall, in a culvert wall. CONSTITUTION:Each deformable joiny 7 is installed in respective culvert wall 4, 5, 6, and it is structured to get its joint intervals contracted by compressive stress acting on a joint filler. Earth pressure p-1 of a top plate before contracting the joint intervals is set to equidistribution. When the joint intervals are reduced by the earth pressure, a sense of main stress of an upper part of the top plate so far being in the vertical direction is changed to an arch form 2, coming to p-2 and p-3, namely it becomes p-3<p-1 in consequence. Also as for a bottom plate lower part, earth pressure distribution is changed to q-2 from q-1, coming to q-3, namely it becomes q-3<q-1. Consequently, a member section is reduced, a required reinforcing bar quantity is reduced and a construction term is shortened in this way.

Filed: 1992-05-22
Abstract: PURPOSE:To prevent the abnormal lighting of a copying lamp by a method wherein an operating means outputs an on-signal only for the specified period of time. CONSTITUTION:A pulse signal is outputted from an AND circuit 46 to the driving part of the copying lamp when a CLPWM signal turns to an H and a CLE signal to an H. The copying lamp is kept lighted when the CLPWM signal is kept output by the malfunction of a CPU. The voltage of the 6pin of a differential amplifier 45 turns higher than the voltage of the 7pin after the time of the time constant of a resistor R160 and a capacitor C115 from the point of the time when the CLE signal turns to the H when the CLE signal attains the state of the H and, therefore, the output from the 1pin turns to an L. The CLPWM signal to the AND circuit 46 turns to the H and the CLE signal to the L and the output from the AND circuit 46 turns to the L. Since the CLPWM signal to the driving part is the L, the copying lamp is not lighted.
