Abstract: PURPOSE:To evaluate reliability of metal wirings due to high frequency current by irradiating a closed coil of metal wiring on a semiconductor substrate with electromagnetic waves to generate alternate current and then by electrifying a coil close to the metal wiring to measure its current value and to detect disconnections of the metallic wiring. CONSTITUTION:A closed coil of metallic wiring 5 on a silicon substrate 1 is irradiated with electromagnetic waves from a magnetron 7 to generate high frequency alternate current. Further, an electromagnetic shield box 6 is temperature-controlled. Next, a coil 9 is made close to the metal wiring 5 and electrified with AC, and its current value is measured. At this time, an AC ammeter 4 indicates a value of the current which is due to flow through the coil 9 if the metal wiring is disconnected. On the other hand, the metal wiring 5 carries induced current to increase the current of the coil 9 if not disconnected. This makes it hard to undergo influence of floating wiring 5 and floating inductance and enables evaluation of reliability of a metallic wiring due to high frequency current.

Abstract: PURPOSE: To make possible repetitive alarming at different intervals by providing plural alarm memory circuits setting plural times and plural counters and coincidence detecting circuits correspponding thereto.  
     CONSTITUTION: A repeat alarm mechanism 18 is provided to an ordinary alarm mechanism. First, the times are set in alarm memory circuits 20, 22 with select SW 48 and set SW 46. Then, SW42 is inputted to open an AND 70 via OR 64, FF 66 and input the signal from a frequency dividing circuit 4 to a counter 24. When the count time of the counter 24 coincides with the memory time of the alarm memory circuit 20, it is detected with a coincidence detection circuit 28 and an AND 82 opens via OR 76, FF 80 to send the signal having been synthesized from the ϕA, ϕC signals from the frequency dividing circuit 4 to an alarm device 50, by which the alarm sound for repeating is produced. A timer counter 86 resets the FF 79 after a fixed time and closes the AND 82 to stop the alarm sound for repeating. As the FF 78 is reset, the similar circuit 100 next operates, thus producing the alarm sound at the storage time of the alarm memory circuit 22.
