Patent number: 7826122Abstract: An optical modulation apparatus that performs optimum bias voltage control for optical modulation without using a pilot tone. A drive unit generates a drive signal by adding a bias voltage to an input data signal. A light modulation unit modulates input light output from a light source unit, in accordance with the drive signal, and outputs the results as optical signals. A forward monitoring unit monitors a forward signal of the light modulation unit and outputs the forward signal. A reverse monitoring unit monitors a reverse signal of the light modulation unit and outputs a reverse signal. A bias control unit controls the bias voltage so that a measured monitor ratio matches a target value of the ratio between the forward signal and the reverse signal, obtained when the operating point of the light modulation unit is in a predetermined position on its operation characteristic curve.Type: GrantFiled: December 23, 2008Date of Patent: November 2, 2010Assignee: Fujitsu LimitedInventor: Tsuyoshi Morishita

Publication number: 20090324256Abstract: In an optical transmitter, a laser emits light. A laser driving controller controls driving of the laser by superimposing modulation signals on laser driving signals to generate laser driving superimposed signals and by applying the laser driving superimposed signals to the laser to cause wavelength fluctuations in laser output light to suppress nonlinear optical phenomena during optical fiber transmission. An optical power variable controller variably controls a power of the laser output light. An optical fluctuation compensator suppresses optical fluctuations by monitoring output light from the variable controller to detect optical fluctuations accompanying wavelength fluctuations from monitoring results and by controlling a gain of the variable controller.Type: ApplicationFiled: February 26, 2009Publication date: December 31, 2009Applicant: FUJITSU LIMITEDInventors: Hiroshi Kuzukami, Tsuyoshi Morishita

Patent number: 7337867Abstract: A vehicle-pedal backward-displacement preventing device. A pedal bracket has side plates each including a front end at which the pedal bracket is attached to the dash pane. A bulge protrudes in a protruding direction away from the other of the side plates. An operating pedal having a depressible portion is provided by its lower end portion. A guide member is associated with an upper end portion of the pedal bracket and a vehicle body member. The guide member causes the upper end portion of the pedal bracket to be downwardly displaced, upon displacement of the pedal bracket, whereby the pedal bracket is deformed with the side plates being made to buckle, so as to restrain the displacement of the depressible portion of the operating pedal toward a driver's seat. Each side plate has an aperture located in its region which includes a crest portion of the bulge, such that a strength of each side plate against a load is reduced most in the crest portion.Type: GrantFiled: November 30, 2004Date of Patent: March 4, 2008Assignee: Toyoda Iron Works Co., Ltd.Inventors: Tsuyoshi Morishita, Hikaru Sugiura, Junji Adachi
