Title: Grooved traverse drum
Inventor: ODOKO NAOJI
IPC: B65H54/48
Filed: 1992-09-30
Abstract: PURPOSE:To provide a grooved traverse drum never generating a traverse slippage on an end surface by shifting turning points in respective grooves of going and returning routes by a specified angle on the side of increasing the turning frequency of the going route, and forming an infection point curved reversely to the turning direction in a point just after both the turning points. CONSTITUTION:The turning point 5 of the returning route 4 of a drum 1 is shifted by 45 deg. in the rotating direction of the drum 1 from the turning point 7 of a going route 6. The direction of this shift is the direction of increasing the turning frequency of the leaving route 6. The shift quantity is 90 deg. at maximum in case of a high turning frequency of the returning route 4, about 45 deg. at maximum in case of a low turning frequency of the returning route 4, 18 deg. at minimum in both the cases, and properly selected within this range. Inflection points 8, 9 curved reversely to the turning direction are formed in positions just after the turning point 5 of the returning route 4 and just after the turning point 7 of the leaving route 6. Thus, a yarn never spring out from the groove, and a traverse slippage on a package end surface can be prevented.

Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To simplify the configuration and to make the size small by discriminating the quality of a reception signal based on a preamble part of a demodulated signal and selecting an antenna based on the quality. SOLUTION: A delay detection section 4 starts demodulation from a preamble part of a received signal and provides an output of the demodulated signal to a clock recovery section 5 and a quality discrimination section 6.

The quality discrimination section 6 writes data evaluating an opening of an eye pattern at an edge of the recovered clock to a table of the state storage section 7 as quality information. At application of power, reception antennas 1, 2 are switched forcibly and the phase information and the quality information of the preamble part of the respective reception signals are stored in a storage information section.  A comparison section 8 selects an antenna with a best reception quality based on the data in the state storage section 7. It is not required to update the state storage data normally or a prescribed time interval.

IPC: G03G21/10
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To obtain a device capable of preventing the clogging of a cleaning brush and maintaining stable cleaning ability for a long time by grasping time when the cleaning brush is reversely rotated and preventing the cleaning brush from being reversely rotated more than necessary. SOLUTION: The time when the cleaning brush is reversely rotated is grasped so as to prevent the cleaning brush from being reversely rotated more than necessary. The use amount of the cleaning brush 2 is measured by a control means related to printing amount after exchanging the cleaning device to the new one.

Thus, the brush part of the new brush 2 whose rigidity is high and where the brush part is napped is prevented from being tilted in a reverse direction and the toner scattering to the outside of the cleaning device caused by the excessive abutting between the new brush and flicker members 3 and 4 is prevented.
