Title: Charge device for capacitor
Inventor: AZUMA MASAO
IPC: H02M3/28
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To protect the circuit element and a device of a capacitor securely by detecting that no detection voltage is applied to a control circuit from a voltage detection system, judging the circuit to have the failure and the abnormal state, and stopping the charging of the capacitor. SOLUTION: The detection voltage of a voltage detector 8 is applied to a comparator CMP when a voltage detection system operates normally, and is compared with the comparison reference voltage of a voltage-setting resistor VR, thus detecting that a capacitor Co has been charged to the comparison reference voltage and hence stopping the operation of an inverter 3 by a control circuit 9A. Here, when the detection voltage from the voltage detector 8 cannot be fetched in due to the removal of a connector that connects the voltage detector 8 to the control circuit 9A or the burnout or the failure of the detector 8 itself, the control circuit 9A determines that the failure and the abnormal state have occurred, thus stopping the charging of the capacitor Co and the operation of the inverter 3 immediately.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To make a plate thickness change time shortest, and to enable the setting and the controls of rolling down position and main machine speed bringing a tension fluctuation within an allowable value by determining the change patterns of initial rolling down position and initial main motor speed from the initial value of a flying plate thickness change time, and operating a plate thickness change time so that a forecaster tension fluctuation falls into an allowable value. SOLUTION: When rolling successively a rolled stock 1 by rolling stands 2a to 2g, the plate thickness schedules and the material speeds of respective stands 2a to 2g after a plate thickness change, are determined by the main machine speed change means 10 and the rolling down position change means 11 of a flying plate thickness change setting means 9 from the pass schedules of the respective stands 2a to 2g before a given plate thickness change and the target plate thickness of a final stand 2g after the plate thickness change. From the maximum movable speed of respective rolling down controllers 3a to 3g, the maximum time of a rolling down position change is calculated. In addition, when the shortest time of either rolling down position change of the respective stands 2a to 2g, exceeds the change time in the final stand 2g, it is adopted as it is.  The change time of a stand on the upstream side is set to this value or over.

Filed: 1995-03-14
Abstract: PURPOSE: To automate frequency adjustment of a PLL synthesizer by supplying a control voltage for frequency setting which is close to a desired oscillation frequency to be set to a voltage-controlled oscillator and locking the voltage- controlled oscillator when an unlocked state is indicated. CONSTITUTION: When the output signal of an unlock detector 58 indicates the unlocked state, the control voltage is set one step higher than a minimum control voltage to detect whether or not the unlocked state is indicated and set one step lower than a maximum control voltage to detect whether or not the unlocked state is shown. Further, voltages which are one step higher and lower are supplied to a D/A converter 56 to detect whether or not the unlocked state is shown. Control voltage data is found by mathematically averaging the sum of a 1st control voltage when the phase is locked by varying the control voltage from low to high and a 2nd control voltage when the phase is locked by varying the control voltage from high to low. A CPU 52 stores the found control voltage data in an EEPROM 54 and uses it for subsequent frequency setting.

The scatter of concrete is therefore prevented greatly by the aluminum plate 2 to reduce labor and time of cleaning concrete scattered around. The aluminum plate 2 is light and easily mountable on the strong damper 1 through the brackets 3.
