摘要： PROBLEM TO BE SOLVED: To permit the use of a widely usable power source, and to reduce cost by additionally providing a mechanism for setting an operating current value of the overcurrent protecting circuit of a power unit again, using the actual value of a load current used as a reference. SOLUTION: An output voltage f of a current detector circuit 7 is inputted to a current detecting protecting circuit 8 and a current value storage circuit 15. This current value storage circuit 15 monitors the current value of the current detector circuit for a preset fixed time, and stores a maximum current value at this time, if a trigger signal k for a set command is generated. To keep the maximum value of this current until the next trigger direction arrives, a means of utilizing a back-up by the use of a battery only for this circuit, using nonvolatile memories, etc., for example are utilized. It is possible to set a overcurrent protecting value corresponding to a load current, by using this stored voltage value as a reference voltage 1 for the overcurrent protecting circuit 8. It is possible to make the output voltage of a reference voltage generating circuit a voltage proportional to a detected current through the operation of a reference voltage generating circuit 14.

摘要： PROBLEM TO BE SOLVED: To prolong the service life of a battery unit by connecting a resistor for shunting a current balancing an apply voltage between the terminals of each battery unit thereby decreasing the number of cells being undercharged or overcharged due to the variation of cell at the time of constant voltage charging. SOLUTION: A reference voltage Vr is set equal to the voltage Vs at a voltage dividing point when the charging voltage Vc is equal to the rated voltage of a battery. When the battery is charged after being discharged, output from a comparison amplifier 21 makes a transition from high to low upon transition of a DC power supply 2 from a substantially constant current operating region to a constant voltage region. Consequently, a relay coil 8 is brought into excited state from unexcited state and relay contacts 8-1, 8-2 and 8-3 are closed to connect resistors 4, 5, 6 and 7 between the terminals of respective battery units. According to the arrangement, the variation in the voltage across the battery can be suppressed and an undercharged unit can be eliminated regardless of the variation of the battery.

摘要： PROBLEM TO BE SOLVED: To obtain an electronic device having a cooling structure where the limitation of installing place is released by discharging the air from the bottom face and the noise is suppressed by enhancing the muffler effect of discharging air. SOLUTION: An exhaust fan 6 is disposed in an air discharge channel 11 between the inner wall of a rear surface and the outer wall 5 of an electronic device 1 and the air is discharged from the upper part of the air discharge channel to the lower part thereof. The air discharged from each rack is collected at the upper part of the air discharge channel and discharged through the air discharge channel 11 and an air discharge port provided in the bottom face of the electronic device. A muffler is disposed in the air discharge channel 11 in order to reduce the noise of discharged air. Furthermore, a channel separator is disposed in the vincinity of the inlet of the air discharge channel 11 in order to prevent formation of an air curtain thus enhancing the cooling efficiency.

摘要： PURPOSE: To improve the availability factor in a service interruption mode through the effective use of a battery and also to surely stop an operation state when a power supply is cut. CONSTITUTION: The power is usually supplied to a main processor 4 and an auxiliary processor 5 from an AC power supply 1 via a power supply controller 3. When the power supply 1 is cut, a battery 2 substitutes for the power supply 1. When the power is supplied from the battery 2, the processor 5 periodically reads the battery discharge current data 32 via a current measurement circuit 11 and an A/D conversion circuit 12 to monitor the remaining capacity of the battery 2. When the battery remaining capacity is reduced less than the prescribed value, the processor 5 instructs the processor 4 to start the shutdown processing. When the end of the shutdown processing is notified from the processor 4, the processor 5 instructs a power supply control circuit 13 to cut the power supply by means of a power supply ON/OFF signal 33.

摘要： PROBLEM TO BE SOLVED: To permit the increase of the number of a body whose rotation is to be monitored without changing the number of anomaly detecting circuits by serially connecting and supplying time-divided rotation signals to an anomaly detecting circuit and artificially performing rotation monitoring on a single body whose rotation is to be monitored. SOLUTION: For monitoring the number of the rotation of cooling fans 1 to 4 by time-dividing, pulse signals 11 to 14 are converted into a single time- divided pulse signal 33 by a selecting part 31 and inputted to an anomaly detecting circuit 21. A determining circuit 24 determines whether a counted value 23 indicates rotation anomaly or not. In the case that it is anomalous, an error flag 25 is raised, and it is notified to an anomaly display device. In this case as well, as in the case of a single fan, a single flag is sufficient. As it is possible to perform the anomaly detection of all the fans by the single anomaly detecting circuit 21 even in the case that there are a plurality of fans in this way, there is no need for providing an anomaly detecting circuit for every fan. This eliminates the need for the modification or extension of the anomaly display device.

摘要： PURPOSE:To automatically change power supply voltage and to automate voltage compensation on a load side by digitizing a measured value from a voltage sensor arranged on the load side and sending the digital value to the power supply side. CONSTITUTION:Direct current(DC) power is supplied from a power supply part 1 to a load part 3 through a power supply line 5. The power supply part 1 regulates output voltage by a feedback circuit 12 within a period of time t1. The regulated output voltage is supplied to the load part 3 through the line 5. A sensor part 2 monitors the voltage of the supplied power on the load side at a prescribed time interval. Voltage measured by the sensor part 2 is converted into a digital signal through an A/D conversion part 22 and the digital signal is inputted to a register part 13 in the power supply part 1 through a control line 6. A voltage regulation instructing part 15 compares the value of the register 13 with an optimum value (reference value) stored in a storage part 14 and determines an excess/lacking regulation value of power supply voltage supplied from a power feeding part 11. The regulation value is converted to an analog value by D/A conversion part 16 to supply to the power feeding part 11.

摘要： PURPOSE:To secure the data saving time by reducing the operation clock frequency of an LSI to suppress the temperature rise of the LSI for a certain time at the time of the abnormal rise of the temperature of the LSI. CONSTITUTION:Though a device is cooled by an exhaust fan 3, an LSI 1 has a large power consumption and the exhaust fan 3 is short of air for the LSI 1; and therefore, it is partially cooled by a cooling fan 2 to supply the shortage. If the cooling fan 2 is abnormally stopped or is rotated at an abnormally low speed or the temperature of intake air is abnormally high, the LSI 1 is thermally destroyed by the temperature rise due to lack of cooling. If the temperature of intake air exceeds a limit value in another case, the LSI is thermally destroyed by the temperature rise. When these abnormalities occur and the abnormality report from an intake air monitor part 5, a fan monitor part 6, or an LSI temperature monitor part 7 is received by a clock varying part 4, the frequency of the operating clock of the LSI is reduced.
