Title: Portable ac power source
Inventor: SHIMIZU MOTOHISA
IPC: H02M7/48
Filed: 1991-06-06
Abstract: PURPOSE:To temporarily lower an output frequency and to cope with the starting transient state of an induction motor, etc., by automatically lowering the frequency of a reference signal when an overload state is detected in an AC generator for forming an AC power by switching controlling an inverter circuit based on the reference signal. CONSTITUTION:The output of an AC generator l is connected to a bridge type inverter 3a through a rectifying and smoothing circuit 2. An output of a VCO 6 which outputs an oscillation signal for forming an output target waveform signal is input to a frequency divider 7 as frequency reducing means. The output of the divider 7 is connected to a sine wave forming circuit 8 as a sine wave reference signal forming circuit. The output of the circuit 8 is input to a PWM 11 as a switch-controller through an electronic variable resistor 9 and an LPF 10. In this case, when an output of a current detector 5 is input to the divider 7 and an overload state is detected, the frequency of a sine wave reference signal is automatically reduced to alleviate a temporarily overload sharing of a power source when an induction motor, etc., is started.

IPC: H04R3/04
Filed: 1989-06-23
Abstract: PURPOSE:To reproduce sound with a low frequency without deteriorating the damping characteristic by feeding back negatively an output of a bridge circuit in which a speaker forms one side to an output amplifier of an equalizer emphasizing the low frequency component of the sound signal. CONSTITUTION:A high frequency component of a sound input is inputted to a tweeter 3 via an amplifier 2. On the other hand, a low frequency component passing through a band limit filter 4 is inputted to an equalizer 10, the low frequency component is emphasized and inputted to a woofer 6 via an amplifier 11. A voice coil of the woofer 6 forms a bridge 17 with resistors 14-16. When the dynamic impedance of the coil changes, the balance of the bridge 17 is changed. An operational amplifier 21 as a negative feedback circuit supplies a signal corresponding to the change in the dynamic impedance to an inverting input terminal of the amplifier 11 via a resistor 23. The low frequency part is expanded by the overall characteristic between the velocity type MFB system and the equalizer 10 constituted in this way.

Title: Recording medium attracting method and image forming device
Inventor: KIMURA TATSUO
IPC: B41J2/01
Filed: 1993-06-10
Abstract: PURPOSE:To silence attraction, miniaturize a device, and improve reliability by attracting a recording medium on a rotor with the Coulomb force acting between charges having different polarities. CONSTITUTION:When positive-polarity high voltage is applied to an electrifying wire 7a, the electrifying wire 7a generates a positive corona discharge to produce positive charges. The positive charges reach a rotor (transfer drum) 6 via a space section, and an insulating material constituting the transfer drum 6 is electrified to the positive potential. Negative charges are implanted by an earth roller 8 into a recording medium sandwiched by the transfer drum 6 and the earth roller 8, and the recording medium is electrified with negative charges. These processes continuously occur while the transfer drum 6 is rotated once. The positive changes and negative charges of the transfer drum 6 and the recording medium attract each other by the action of the Coulomb force, and the recording medium is attracted onto the transfer drum 6 as a result. The high voltage application stop period is measured after the high voltage application is stopped, and the polarity of the applied high voltage is reversed when the prescribed period is measured.
