Title: Withstand voltage testing apparatus
Inventor: IKETANI IKUYA
IPC: G01R31/12
Filed: 1995-06-07
Abstract: PURPOSE: To obtain a withstand voltage testing apparatus by which a corona generation amount can be detected accurately. CONSTITUTION: In the withstand voltage testing apparatus, a corona voltage which is generated at an object 2 to be tested is detected on the basis of a testing voltage applied to the object 2 to be tested. The withstand voltage testing apparatus is provided with an A/D conversion means 3 by which a voltage generated across terminals of the object 2 to be tested is converted into digital data, and a corona-amount extraction means 4 by which a corona amount superposed on the testing voltage is extracted from the digital data converted by the A/D conversion means 3. In addition, the corona-amount extraction means 4 computes a difference at each cycle of the testing voltage so as to define the corona amount, and it detects a maximum value as the maximum value of a corona voltage.  Alternatively, it detects the maximum value of the corona voltage, and it finds the ratio of the maximum value to the testing voltage. By this constitution, a corona generation amount can be detected accurately, and a withstand voltage defect can be judged precisely.

Title: Original feeder in facsimile
Inventor: KURAMOTO HIROSHI
IPC: H04N1/00
Filed: 1983-07-30
Abstract: PURPOSE:To eliminate the need for a discharge sensor without deteriorating the function of original feeding by setting a scheduled time when the tip of an original reaches a discharge roller from the detection to a counter at the detection of an original by a sensor. CONSTITUTION:The number of pulse (a) of a motor required to feed an original P by a distance (d) between a reading section 9 and the discharge roller 10 is preset to the 1st counter 16. The number of pulses (b) feeding the original slightly longer than the normal original is set to the 2nd counter 17. When the tip of the original does not reach the reading section 9 even if the counter 16 counts the set value (e), the counter 17 awaits the setting value (b), and when a sensor 2 is turned off even after the confirmation of the setting value (b), an output 1 of the counter 17 clears both the counters via an OR gate 15, the output of the counter 16 is changed from 0 to 1, a clutch 14 is turned on and the original is fed. Since the distance from the original reading section to the discharge roller is measured in advance and the roller is turned by the number of pulses of the motor corresponding to the said distance, a sensor at the position of discharge roller is not required.

The signal of the amplifier A6 is fed to a DC amplifier A7 for controlling collector current, its output becomes a collector current control signal of amplifiers A1-A5 and the collector current is controlled to be smaller when the input signal level is small. Thus, the amplification factor of the amplifiers A1-A5 is almost unchanged and no deterioration in the noise figure is caused.

Abstract: PURPOSE:To prevent the increase of the memory capacity and the disk capacity by selecting the trace information based on the trace control telegram received from a host to store these trace information and therefore acquiring the fault information with limitation. CONSTITUTION:A main control part 12 analyzes the telegram reported from a communication control part 11 and received from a host and the input information reported from an input/output control part 16 and received from a display device. Then the part 12 reports the process requests to a trace analyzing part 13 and a work processing part 14. The part 13 reports a trace processing part 15 with a trace control telegram whether the traces should be acquired or not for each module of the part 14, etc. The part 15 stores and records the trace information into a memory or a disk device by the trace report. Thus the fault information can be acquired in accordance with the fault state and therefore the extra information having no relation with the fault is never acquired. Thus it is possible to acquire the fault information for a long period of time without increasing the memory capacity and the disk capacity.
