Abstract: PURPOSE:To make it possible to simply, efficiently and continuously detect a defect in all directions with high accuracy, by arranging multi-pole electromagnets at a plurality positions toward a longitudinal direction from the end surface of a tubular material to be inspected in opposed relation to said tubular material while rotating the material to be inspected around its shaft. CONSTITUTION:A magnetic flaw detecting apparatus 11 is inserted into an object 12 to be inspected from the end part thereof in the axial direction. The three- pole type electromagnets 14 of the magnetic flaw detecting apparatus 11 are arranged at positions facing to the outer surface of the material 12 to be inspected while three-pole type electromagnets 15 are arranged at positions facing to the inner surface of the object 12 to be inspected.

IPC: G06E1/00
Filed: 1990-04-18
Abstract: PURPOSE: To increase sensitiveness for optical input signals without reducing switching speed by applying excitation so that optical bistable devices are set in a metastable state, applying the optical input signals and removing excitation. CONSTITUTION: The processing performance of the optical digital processing system having the optical bistable devices 1 and 2 having the metastable state M between two stable states A and B in response to the optical input signals PIN1 and PIN2 is increased. Then, excitation is applied so that the optical bistable devices 1 and 2 are made into the metastable state M and the optical input signals are applied to the optical bistable devices and excitation is removed. The operation of the optical bistable devices making the devices in the metastable state reduces the condition of the power of the optical input signals before the devices are switched and whole switching time can be shortened. Thus, sensitiveness for the optical input signals can be increased without reducing switching speed.

Abstract: PURPOSE:To prevent the generation of unstable operation in the operating state of a central processing unit (CPU) by turning a power supply control circuit to a backup state after surely ending initial resetting operation and surely setting up the CPU and its peripheral devices to backup states. CONSTITUTION:When the CPU 20, a RAM 30, a ROM 40 and peripheral circuits are mounted in a vehicle and connected to a car battery 10, voltage VDD outputted from the battery 10 is impressed to the CPU 20 through the 1st regulator 11. Then an RST detecting circuit 42 detects whether the voltage VDD is potential capable of operating the CPU 20 or not, and when the potential disables stable operation, outputs an 'L' level RST signal. When the stable operation is possible, the signal RST is turned to the 'H' level to start the CPU 20. In this case, the output of the circuit 42 is outputted also to a Shmitt circuit 43, the preceding 'L' level signal is stopped, the 'H' level signal is delayed by a delay circuit 44, and the delayed signal is outputted to an OR circuit 45. Then, a switch 12 is turned on by the output of the circuit 45 to impress a prescribed voltage to the ROM 40 and the peripheral circuits.

Abstract: PROBLEM TO BE SOLVED: To obtain an evaluation technique in which a creep life consumption rate can be evaluated with high accuracy even by an unskilled operator, by a method wherein the maximum value of the grain boundary occupation rate of a creep void generated in every crystal grain boundary of a member is measured and the creep life consumption rate of a creep-degraded apparatus member is estimated. SOLUTION: A part in which a creep void is recognized is observed at an arbitrary magnification by using a scanning electron microscope, an optical microscope or a laser microscope, and the maximum part of a creep void crystal grain boundary occupation rate within its visual field is measured. The maximum part is fitted to a master curve obtained by an experiment, and the creep life consumption rate of a member is estimated. For example, the ratio of the length lα of a creep void on a crystal grain boundary occupied by the length Lα of a crystal grain boundary in which the creep void exists is calculated, and a maximum void grain boundary occupation rate is found.  When the maximum void grain occupation rate is fitted to a master curve obtained by an experiment, the creep life consumption rate of the member to be evaluated can be evaluated, and the consumption rate can be measured every simply even by an unskilled operator.
