Filed: 1987-06-18
Abstract: PURPOSE:To achieve a reduction in analysis time, by a method wherein an identification code of a part to be measured is inputted to read a reference value of characteristic from a memory means and input and output signals of a corresponding part being measured are sampled to be compared therewith. CONSTITUTION:When a type code of a part 1a to be measured is inputted from a keyboard 2a, input and output signals of the part 1a are sent to a sampling circuit 4a and a timing and level of the output signal are sampled to be stored into a data buffer 5 and a data D thereof is sent to a comparison/ judgement section 6a. On the other hand, a searching circuit 3a reads an allowable limit value S from a reference value file 3b by the type code to be sent to the judgement section 6a, which compares the data D with the limit value S. When the data D is within the limit value S, the part is determined to be acceptable and when it exceeds the value S, the part is done to be a reject. The results of the judgement are displayed on a CRT8 while printed out with a printer 9 thereby achieving a reduction in analysis time.

Title: Current detecting apparatus
Inventor: ISHIGAMI YOSHIHISA
IPC: G01R19/00
Filed: 1982-08-31
Abstract: PURPOSE:To rapidly raise the output voltage of a power source circuit after AC power force is applied and to operate the titled apparatus within a short time, by providing a starting circuit having a switching element electrically conducted when the output voltage of the power source circuit exceeds the predetermined voltage. CONSTITUTION:When AC electric power is applied through lines 31, 32, a power source circuit 2 converts said AC electric power to DC electric power. When AC electric power is applied, the transistor Tr 35 of the start circuit 3 is cut off. Therefore, impedance connected to the DC electric power output side of the circuit 2, that is, between lines 33, 34 is high. Therefore, the voltage between the lines 33, 34 abruptly becomes high. When voltage between the line 33 and an earth exceeds the zener voltage of a zener diode 37, Tr 35 is electrically connected. By this mechanism, impedance becomes low. Therefore, the supply of DC electric power to a magnetic multi circuit 4, duty detecting circuits 5, 6, differential amplification circuit 7, a level discrimination circuit 8, a response circuit 9 and a voltage detecting circuit 10 is sharply performed and a current detecting apparatus 1 is rapidly operated.
