Title: Evaluation method of congested cracks on surface of solid by ultrasonic waves
Inventor: YOKOYAMA KEIJI
IPC: G01N29/44
Filed: 1993-12-21
Abstract: PURPOSE:To provide an evaluation method which precisely detects the position of cracks in a wide range of depth and which can quantify their depth. CONSTITUTION:An object 1 to be tested is immersed in a liquid such as water or the like. A probe 3 for emitting ultrasonic waves as longitudinal waves, which converge at a definite focal distance, is arranged in the liquid so as to form a focus on the surface 2 of the object. While ultrasonic pulses as the longitudinal waves from the probe 3 are being incident on the surface 2 of the object in such a way that their angle of incidence thetai becomes equal to a critical angle thetacs generated by surface waves. The probe 3 is scanned, along the surface 2 of the object, in a direction nearly perpendicular to a direction in which a crack 4 is caused. The position and the depth of the crack 4 which is comparatively shallow are measured. While the pulses are being incident at the incidence angle thetai at which angle of refraction thetaL of the longitudinal waves is <=90 deg., the probe 3 is scanned along the surface 2 of the object. The position and the depth of the crack 4 which is comparatively deep are measured.

Title: Discharge lamp lighting device and luminaire employing same device
Inventor: URATANI KAZUYUKI
IPC: H05B41/24
Filed: 1991-12-27
Abstract: PURPOSE:To prevent a control circuit from being erroneously operated by allowing a reset signal to be sent out of a reset circuit when a discharge lamp is removed out of a number of lighted discharge lamps. CONSTITUTION:When a discharge 10 for example, is pulled out of its socket section 14 by mistake while the discharge lamp 9 and another 10 are on a detection signal S1 higher in voltage than reference voltage Vf, is applied to the non-turn-over input terminal of a comparison circuit 21, the output of the circuit 21 is turned out to be H so as to be added to an AND gate 22, and consequently a L signal which has been turned over by an inverter 23, is inputted into a flip flop 24. Since the FF 24 set in advance remains to be H before a set signal comes in, the gate 22 corresponds to the value of H, consequently the pulse signal of H which is to be outputted when one discharge lamp is pulled out, is sent as a reset signal S2 to a control circuit 17. The pulse width of the signal S2 is determined by the timer time of a timer circuit 25 for resetting the FF 24. By this constitution, resetting both a protection circuit 18 and a drive circuit 19 within the circuit 17 can prevent the circuit 18 from being erroneously operated.

IPC: C21D9/02
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To regulate the crystal orientation of martensitic phases in a steel wire and to improve its rigidity, at the time of holding a spring steel wire under heating to the A3 point or above and thereafter executing quenching, by applying the magnetic field having intensity in a specified range in the direction of the wire axis. SOLUTION: A spring steel wire is heated to the A3 point or above. Next, at the time of its transformation into martensite by quenching, the magnetic field of 0.5 to 5 tesla is applied in the direction of the wire axis. By this treatment, a spring wire rod in which the [100] orientation of martensitic phases by >=50% is orientated in the range within 30 deg.C to the direction of the wire axis is produced. In the case of the transformation into the martensitic phases, by applying the magnetic field, the [100] orientation which is the easily magnetizabile direction in the martensitic phases is made easy to grow. By the application of the magnetic field, the orientational regulation of martensitic lath can be executed to uniformize the crystal orientations. Thus, in accordance with the anisotropy as that of the steel wire, its rigidity improves.
