Title: Original cover plate opening/closing device and spring adjuster
Inventor: FUJITA CHISHIRO
IPC: G03B27/62
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To easily correct a change with a lapse of time in the elasticity of springs expanded/contracted at the time of opening/closing an original cover plate, even if the change with the lapse of time occurs, in an original cover plate opening/closing device having a lift support. SOLUTION: When the opening/closing operations of the original cover plate 4 are executed in a great number of times, the springs S1-S3 are gradually exhausted because they are expanded/contracted in a great number of times, so that the elasticity in the beginning can not be obtained. In such a case, in a state where the original cover plate 4 is opened, a wrench is inserted through an operation hole 38, to turn a nut 44 and move a spring tray 45 upward. Thus, the stroke of the spring S2 is made shorter than that until then, to recover the elasticity.

Title: Voltage controlling circuit for inverter
Inventor: KUROKI KAZUO
IPC: H02M7/5387
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation of transient voltage and make a stable operation with zero steady voltage deviation stably by making an adjustment by a first regulator so that the deviation of a voltage actual value from a voltage target value may be zero and making an adjustment by a second regulator so that the deviation of an AC voltage signal from a reference sine-wave signal which is the output of the first regulator may be minimum. SOLUTION: The AC voltage detected by a potential transformer 11 is rectified by a rectifier 12 and then is smoothed by a smoothing circuit 13 to obtain a voltage actual value signal. The deviation of the voltage actual value signal from a voltage target value signal set by a voltage setting device 14 is input to a first regulator 15 to adjust the deviation to zero. On the other hand, the output voltage of an inverter is input to a first signal multiplier 31 and the output of the first signal multiplier 31 and a reference sine-wave signal output from a sine-wave generating circuit 16 are compared by an adder 21 and a difference between the two signals is so adjusted by a second regulator 22 so that it may be minimum. By this method, the transient fluctuation of voltage can be held as small as possible and the deviation due to the steady fluctuaion of voltage can be made zero.

Abstract: PURPOSE:To protect an output transistor(TR) from being destroyed by providing a time constant circuit comprising a capacitor or the like having a prescribed charging time constant and a bypass TR controlled in response to a charging voltage of the capacitor. CONSTITUTION:A time constant circuit 17 comprising a Schottky diode 18 and a capacitor 19 or the like is connected between a base and an emitter of a bypass TR 14. Thus, before the TR 14 is conductive, the diode 18 is conductive and a voltage in response to a current flowing to a collector of the output TR 1 is not immediately to af base of the TR 14 but the capacitor 19 is charged. In this case, the charging is applied in response to the charging time constant depending on the capacitor 19 and resistors 10, 13 or the like and discharge is applied in response to the discharge time constant depending on the capacitor 19 and a resistor 21. Till the charging voltage of the capacitor 19 reaches a prescribed level, the TR 14 is kept interrupting, then the input signal is limited when a large signal is continuously inputted to protect the TR 1 from the destruction.

Filed: 1996-10-03
Abstract: PROBLEM TO BE SOLVED: To surely reduce harmonic voltage even in the case of current injection for requesting a system impedance by setting up the phase standard of an optional current output injected into an electric system as the phase mean value of the harmonic voltage in a fixed time zone before the current injection. SOLUTION: The measurement of system impedance Zsys is carried out in the circuit formation of an active filter AF. An optional fixed output current is generated in an inverter part 1 for generating a compensating current before compensating actuation, and a current output is carried out to its own system through an injection circuit part 2. Before injecting the current output to the system and in the case of injecting an optional current output, the harmonic voltage at an optional time is measured in a harmonic voltage detecting section 3. A signal processing section carries out the computing process of the system impedance Zsys on the above detected value.  In the computing process of the system impedance Zsys, the detected value of the harmonic voltage is levelled through A/D conversion and fast Fourier transform, and after inverse Fourier transform, D/A converted to set up an inverter current output command.

Abstract: PROBLEM TO BE SOLVED: To provide an offset-adjusting circuit, in which the influence of asymmetry is reduced and in which the error rate of reproduced data can be reduced by a method where the offset of a reproduced signal is removed, when the signal of an optical disk is reproduced and an offset which is generated due to the asymmetry is corrected and to provide a reader which uses the offset- adjusting circuit. SOLUTION: In this reader, the DC component of a reproduced signal Sin from an optical pickup is removed by a capacitor 20, and a signal SA which contains only an AC component is obtained. By a peak hold circuit 30 and a bottom hold circuit 40, a peak value P and a bottom value B of the signal SA are found respectively. Based on these values, an offset-adjusting value (P+B)×k is calculated. A signal SL as an offset-adjusting signal, in which a high-frequency component contained in the value is attenuated, is added to the signal SA. Thereby, the offset of the reproduced signal Sin is adjusted, and the influence due to asymmetry can be suppressed.
