Title: Light modulator
Inventor: WATANABE SEIJI
IPC: G02F1/035
Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To inhibit the deterioration of transmission characteristics due to the light- polarization dependence of an optical direct amplifier used for ultra-long-distance transmission system. SOLUTION: In a light-intensity modulation section 1 of this modulator, an optical signal made incident on a polarizer 4 while maintaining the polarization plane by using a polarization maintaining optical fiber 3 is passed through the polarizer 4 to convert the optical signal into linearly polarized light and the linearly polarized light signal is inputted to an optical waveguide 7 formed by thermally diffusing titanium on a lithium niobate substrate 5. In the optical waveguide 7, the inputted optical signal is branched at the first branchpoint into two equally branched optical signals and these branched optical signals are recombined at the second branchpoint into a single intensity-modulated optical signal. In a light-polarization modulation section 2 of this modulator, the polarized state of the optical signal outputted from the light- intensity modulation section 1 is converted into linearly polarized light having a 45 deg. rotation angle of the polarization plane by passing the outputted optical signal through a polarizer 10 and the resulting linearly polarized light signal is inputted to an optical waveguide 11. In the waveguide 11, when a voltage is applied to a signal electrode 8, the polarized state of the inputted optical signal is successively, forcedly and regularly modulated.

Filed: 1979-02-26
Abstract: PURPOSE:To so support a vessel that it turns when the specified volume of toner is contained therein, accurately detect the toner volume from its turning and suppress toner leakage through the toner accepting port of the recovery vessel. CONSTITUTION:Toner removed by a blade 8 from an image carrier is conveyed and is subsequently contained in a toner recovery vessel 13 by the screw 10 which is driven to rotate in a toner conduit 12 being a conveying means, below a casing 7. The vessel 13 has no toner therein and while the toner volume is small, it slightly tilts as shown by the chain line as a turning habit in a clockwise direction about a pin 111a together with a support member 112 is given thereto by a tension spring 118. However, when the toner volume in the vessel 13 increases, the vessel 13 assumes the position shown by the solid line and since an operating member 119 causes an actuator 121 to operate to turn on a switch 120, it may be detected from this that the toner is filled in the vessel.

Abstract: PURPOSE:To start picking a next paper sheet before the preceding paper sheet is completely discharged by a method wherein such constitution is made that a discharging roller always rotates in a direction of discharging paper sheet when the rotation of a driving source is reversed. CONSTITUTION:When a driving source 5 is rotated clockwise, a pick roller 2 rotates clockwise to start feeding paper sheets. At this time, a discharging roller 4 rotates in a direction of discharging paper sheets being driven by a first transmission system 28. This is because a lever 30 rotates counterclockwise and a first gear 31 is engaged with a gear 33. Then, a paper sheet reaches the specific position after the driving source has rotated for a specified time, the driving source 5 is rotated counterclockwise. At this time, the paper sheet is sent to a printing unit to be subjected to printing process. When this driving source 5 is rotated counterclockwise, a driving gear 22 rotates clockwise, a lever 30 also makes turning movement clockwise and a second gear 32 is engaged with a gear 34. In this case, the discharging roller 4 also rotates in the direction of discharging paper sheet. Thus, the discharging roller always rotates in the direction of discharging paper sheets.
