Title: Exposure amount adjusting device of copying machine
Inventor: TAKEMURA YUKIO
IPC: G03G15/04
Filed: 1980-07-22
Abstract: PURPOSE:To prevent deterioration and fogging of an image and to remve polarized harmful light by preparing two polarization filters in an optical path, by rotating relatively and by adjusting an amount of exposure without preparing an opening. CONSTITUTION:In stead of an opening, two polarization filters 10, 11 are prepared in an optical path, and by rotating them relatively, an amount of exposure is controlled. When a polarization axes of the polarization filters 10, 11 were aligned in  the same direction, an amount of transmitting light becomes maximum, and when polarization axes of polarization filters 10, 11 are crossed perpendicularily an amount of transmitting light becomes minimum. To remove harmful light such as polarized positively reflected light from the manuscript surface, the polarization filter 10 may be fixed. A polarization film may be prepared to on a lens plane, a mirror plane and an in mirror plane of an in mirror lens.

Abstract: PURPOSE:To eliminate a color shift at color transfer by detaching a pressing roller from a platen during the time when a material to be transferred is not fed to the platen. CONSTITUTION:A solenoid 66 is excited until the tip of a form which is wound to a platen 10 and transferred at transfer operation reaches between the platen 10 and a pressing roller 20, and the roller 20 is detached from the platen. The second pressing roller 19 is also controlled by a solenoid 76 in the same way. The form is wound to the platen 10 and one color is transferred by a printing head 11. As a result, the form is returned to its original state, another color is transferred by the printing head again, and the color transfer is executed. The pressing rollers 19, 20 remain detached from the platen 10, therefore, a position shift of the form is prevented, and the color shift is eliminated.

Title: Tension controller
Inventor: OOTA OKISHI
IPC: G11B15/43
Filed: 1988-04-22
Abstract: PURPOSE:To unify tape tension by generating torque proportionate to tape travelling speed and reel rotational period. CONSTITUTION:The traveling speed of a tape 1 driven at a uniform speed by a tape driver 8 is detected by a speed detector 7 and the rotational period of a reed 2 is transmitted to a rotation detecting circuit 5 through a rotation detector 4. The circuit 5 outputs a signal proportionate to the rotational period of the reed 2 and the tape speed by the outputs of the detectors 4 and 7. When the tape is driven at the uniform speed, the rotational period of the reel 2 is proportionate to the radius of the reel 2 including the thickness of the tape, the ratio of the generated torque in the reel driver 3 to the radius of the reel 2 is kept uniform and the tension to the tape 1 becomes uniform. When the tape speed becomes (n)-fold, output of the detector 7 becomes (n)-fold, the output of the detector 5 does not change, the tension applied to the tape 1 is controlled at a uniform value, therefore, when the winding diameter of the tape or the tape speed changes, the uniform tension can be always applied to the tape.

IPC: E02D29/14
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce machining cost for a protection cover used for a vinyl chloride small-bore manhole. SOLUTION: A protection cover 5A is formed of a casting lid 7 having an antiskid finish on the upper surface, a casting ring part 14 having a collar 6a for supporting the lid 7, a cylindrical part 13 as a body separate from the ring part 14 but coupled, and a settlement preventing plate 9a for supporting the cylindrical part 13. Instead of loosely coupling the lid 7 to the ring part 14, the lower surface periphery of the lid 7 and the upper surface of the collar 6a are knurled, thereby stopping the rotation 11 of the lid 7. According to this construction, a knurling process does not need the consideration of a casting size error for a casting, and simply requires rough machining. Machining cost or a percent defective can be thereby reduced.
