Title: Phase signal filtering device
Inventor: KURODA MASAHIRO
IPC: H03H17/00
Filed: 1988-07-01
Abstract: PURPOSE:To narrow an inherent frequency to a limit by constituting a PLL circuit into two stages and PLL-filtering the residual phase signal of a phase into signal and an estimation phase signal at the time of processing signals different in a phase. CONSTITUTION:A first signal phi1 (t) is added to an estimation phase signal generation part 1, where the signal is filtering processed, and it is outputted as the estimation phase signal phi'1 (t). The noise of the signal is suppressed by the operation such as the averaging of a generation part 1, and the signal is used as the generation signal of a second signal phi2 (t). The PLL circuit consists of a phase comparator 4, a low pass filter 5, a voltage controlled oscillator 6 and a phase adder 7, and the signal phi2 (t) is outputted as an output phi'2 (t) which is almost equivalent. Since the filter 5 and the oscillator 6 have the response characteristic of the low band filter at that time, noise is suppressed. Furthermore, there is the phase adder 7, and the estimation phase signal is used, whereby an effect on Doppler shift which the signal of a GPS satellite is also suppressed in the output level of the phase comparator 4.

Title: Image forming device
Inventor: KOMATA HARUHIKO
IPC: G03G15/16
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To supply an adequate current required for transfer electrification and to prevent the occurrence of transfer defect by changing a transfer electrification current in timing that a recording material is brought into contact with a conductive member (driving roller) or the recording material is brought into contact with the conductive member through a dielectric. SOLUTION: A current flows by an installed constant current power source 70 separately from the current of 10 μA supplied from a normal constant current power source 60d to a transfer electrifier 24d. Thus, a constant current can be controlled so as to compensate the current flowing the driving roller 13. The power source 70 is controlled in sequence that the power source 70 is turned on only when the recording material shortcircuits between the fourth transfer charger 24d and the roller 13 and turned off in other cases even in the case of image formation. At this time, the current of 5 μA flows by the power source 70. Thus, the power source flowing to the roller 13 can be compensated. Besides, the same effect can be obtained even when the output of one constant current power source is changed by the use of software.

Abstract: PURPOSE:To reduce the installation space by allowing a small quantity of liquid to develop a large brake lowering by installing a damping means in shiftable manner in the horizontal direction in the liquid in the center part in the wave motion direction in a tank and connecting a reciprocating driving means which shift-drives the damping means in the horizontal direction, with the damping means. CONSTITUTION:When a structure I vibrates horizontally, a vibration sensor 9 detects this vibration, and outputs a signal to a vibration suppressing device 10. The vibration suppressing device 10 drives a hydraulic actuator 7, and a rod 7a is reciprocatingly driven in the state conforming to the vibration frequency of the structure I in the A and B directions. Then, since also a damping plate 6 is driven in the A and B directions, the liquid 5 stored in a tank 3 is directly allowed to generate wave motion through the tank 3 by the swing of the structure I itself, and wave motion starts in the longitudinal direction of the tank by the reciprocating shift of the damping plate 6. The wave motion pattern of the liquid 5 is controlled by the vibration suppressing controller 10 so as to offset the vibration generated on the structure I, and the vibration of the structure I is speedily attenuated.
