Title: Data separation circuit
Inventor: NAGAI TSUNEO
IPC: G11B20/14
Filed: 1987-09-14
Abstract: PURPOSE:To improve the stability of operation by connecting the capacitor of a loop filter to the other capacitor which is bigger than that in parallel. CONSTITUTION:A loop filter time constant changing control circuit 10, a loop filter charge circuit 11, a loop filter switching control circuit 12 and a switch circuit 13 are added to a conventional circuit. That means, they works to make the capacity of their capacitors big after the synchronization of a phase locked loop (PLL) by connecting the other capacitor to the capacitor of the loop filter in parallel. Then, they works to make the capacity of the capacitor of the loop filter small and to charge the other capacitor at the same time by separating the other capacitor before a synchronizing signal is inputted or when the PLL cannot follow the inputted signal. At the time when the capacity of the capacitor is switched, the difference between the charge quantity before and after the switching becomes small and that makes the extraction operation of a self-clock stable.

Abstract: PROBLEM TO BE SOLVED: To prevent image staining caused by the soiling of a cleaning member for recycling toner by applying discharge bias having an opposite polarity to recovery bias to a cleaning roller member in an image non-forming area and discharging toner on the cleaning roller member to an image forming body. SOLUTION: The toner left after transfer on the peripheral surface of a photoreceptor drum 10 reaches a cleaning device 190, and re-electrified by a re-electrifying roller 192.

Title: Laser light source
Inventor: SUGIYAMA SUNAO
IPC: H01S5/00
Filed: 1987-09-14
Abstract: PURPOSE:To obtain a mechanically and thermally stable optical characteristic immediately after a laser drive operation by a structure wherein a pumping beam passed through a phase conjugate mirror is reflected and returned to an original position, a reflected beam of the mirror is restrained from returning to a laser and a standing wave is generated by the reflected beam of the mirror and the pumping beam. CONSTITUTION:A beam radiated from an end face 11 is passed through a crystal 2; it becomes a parallel beam by means of a collimation lens 3; it is reflected by a mirror 4; it is passed through a beam isolator 5; it is reflected by a mirror 6; it is passed through the crystal 2 again; it is reflected by a mirror 7; it is returned to an initial light path in a reverse direction. A standing wave is generated between a forced pumping beam and a reflected beam of the mirror 6, and immediately generates its phase conjugate wave against an incident beam from a laser 1. As a result, the crystal 2 acts as an external resonator of the laser 1; a reflected beam of the mirror 7 is blocked by the beam isolator 5 in such a way that it does not disturb a resonance state by returning to the laser 1. When the laser emits a beam, a phase conjugate mirror is operated immediately whereby a response performance is very excellent.

Abstract: PURPOSE:To accurately obtain a stereoscopic sound with enough presence feeling by bisecting the frequency band of a sound signal and permitting an electroacoustic transducer to convert the one into a sound wave and rendering a bone propagation receiver to convert the other into a vibrating sound. CONSTITUTION:A division circuit 11 bisects the sound signal into the frequency band of which the electroacoustic transducer 12 and the bone propagation receiver 14 are charged. Out of 1st and 2nd sound signals, the 1st one is converted into a sound wave by the electroacoustic transducer 12 to vibrate eardrums, while the 2nd one is converted into a mechanical vibration by the bone propagation receiver 41 to transmit it to a skull. As another method, a filter 14 takes out only signals in a specific frequency range among sound signals, that is, signals in low and high frequency ranges, to which ears hardly hear. The taken- out signals are transmitted to the skull through the bone propagation receiver 14. Thus presence feeling is enhanced.
