摘要： PURPOSE:To exactly monitor spark, by receiving spark noise and external noise with a first antenna of two electromagnetic wave receiving antennas arranged near collector rings and brushes, and external noise with a second antenna, and by finding out the difference between the both receptions. CONSTITUTION:Direct current obtained by rectifying an AC power source 12 is fed to bush rings 5 via exciting wires 14. The direct current is fed from the bush rings 5 to collector rings 1, 2 via lead wires 4 and brushes 3. Near the bush rings 5, an electromagnetic wave receiving antenna 7 is set, and noise due to spark generated by the brushes 3 and external noise are received. Outside a shielded locker section 6, an antenna 8 receiving the external noise only is set. The outputs of the antennas 7, 8 are input to a noise detecting section via a connector 9, and when the output different is a specified value or more, then an alarm 11 is driven. As a result, the spark monitoring of high reliability is performed.

摘要： PROBLEM TO BE SOLVED: To effectively utilize a mail server resource in an overall system to occurrence of a fault in a certain specific transmission destination mail server or path. SOLUTION: This mail server system includes: a convergence control management part 120 for managing convergence control of an overall mail server system; a convergence statistical information collection part 119 for collecting convergence statistical information of each mail server 120; and a retry server 103 having a retransmission queue 117 having sufficient capacity for performing retry. When detecting a mail server causing a fault from the collected convergence statistical information, the convergence control management part 120 provides a direction of mail transmission restriction addressed to a faulty mail server to each mail server 102. The mail server 102 provided with the direction of the mail transmission restriction addressed to the faulty mail server transfers all the mails addressed thereto to the retry server 103, and transfers the received mails addressed to the faulty mail server to the retry server 103 until a restriction canceling direction is issued from the convergence control management part 120.

摘要： PURPOSE:To prevent an abnormal read image from being transferred as it is by measuring the time from the start to the end of a read of a specific field and sending read handwriting image data to a host device only when the specific field is read within a specific time. CONSTITUTION:When a sensor 6 detects an application form 11 which has necessary items entered into the specific field, an image reader 2 makes preparations for reading and detects an application read start mail 12 a specific time later to read the contents. A timer measures the read time. Then when a sensor 7 detects the application form 11, the operation of the image reader 2 is ended and a mode 10 is stopped. When the image reader 2 detects a reference character 14 during this period, the timer finishes the measurement, the scanning time from a read start mark 12 to the reference character 14 is monitored, and it is checked whether or not the monitored time is within a specific range; and it is confirmed that there is a slip on none of conveyor rollers 1a-1d and only when no slip is confirmed, data are transferred to the host device.

摘要： PURPOSE:To suppress surge voltage and reduce a loss from a power source and thus obtain a miniaturized power source for a laser efficiently, by providing secondary windings for a stabilization reactor and regenerating energy stored in the stabilization reactor toward the preceding stage of a voltage control circuit which is arranged at the input side of the stabilization reactor. CONSTITUTION:This device allows secondary windings of a stabilization reactor 14A to be clamped by voltage at both ends of a smoothing capacitor 4 and voltage which is determined only by a turn ratio is impressed at the primary side. The proper application of the turn ratio makes it possible to suppress voltage produced at the primary side of the stabilization reactor 14A to a level that is less than constant voltage. Similarly, even when FETs 9B and 9C for switching is turned to ON, the same operations are repeated. Further, even when the FET 9B and 9C for opposite phase switching is turned to ON before the regeneration of the stabilization reactor 14A is completed, its regeneration is kept on and there is no effect on the opposite phase.

摘要： PURPOSE:To prevent the generation of the flaw on the strip end face by a roller without dropping a belt wrapper by sliding the magnet provided on a magnet frame in the width direction of the strip according to the meandering detection amt. of the strip. CONSTITUTION:The meandering amt. of a strip 3 is detected by an EPC detector 2 to follow up a deflector roll 10 and winding drum 7 while under winding. After shearing the strip 3 the tailend of the strip 3 is separated from the EPC detector 2 and unable to be controlled with a tensile force being eliminated on the strip 3, so it is followed up to the meandering amt. of the strip 3 together with a tailend guide roller 12 by attracting by the marget 5 of the magnet frame 4 actuated precedingly prior to shearing. The generation of the flaw on the strip end face by the tail end guide roller 12 and the winding slippage by the winding drum are thus prevented.
