Inventor: ITO YUJIRO
IPC: H04B10/11
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of optical beam transmission by constituting an optical axis correcting means to correct the optical axis of an optical beam only when the variation of an incident angle is out of a prescribed range based on the variation of the incident angle of the optical beam detected by an angular variation detecting means. SOLUTION: Inside of an optical axis correcting part 19, a skew sensor 22 for detecting the inclination of a mirror 21 is provided to constantly send a detecting result to a skew angle detecting part 23. The part 23 sends an angle detecting signal S2 corresponding to the inclination of the sensor 22 with respect to the direction of two axes to a CPU 24. Then, the part 19 corrects the emitting direction of a transmission light beam L10 based on the control of the CPU 24 and then guides it to a lens 28. The lens 28 diverges and emits the beam L10 and a large diameter lens 29 in a transmission optical system 15 converts this divergent light into a nearly parallel light beam and emits it. Thus, an optical communication equipment 10 transmits an information signal by the beam L10.

Title: Operational amplifying device
Inventor: UGAJIN MAMORU
IPC: H03F3/34
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To enable formation by an LSI process and to make the accuracy of offset compensation high by connecting a differential amplifier and a single- output operational amplifier via two capacitors which have the same capacitance. SOLUTION: The outputs and inputs of an operational amplifier A12 and a single-output operational amplifier A11 are connected via capacitors C1 and C2, and a reference potential is applied to the inputs of the respective amplifiers via switches S3 and S4, and S1 and S2. For offset compensation, the switches S1 to S4 are closed, and switches S5 and S6 of an input circuit are opened, so that the voltage obtained by multiplying the offset voltage of the differential amplifier by a voltage gain is stored in the capacitors C1 and C2. Then the switches S1 to S4 are opened, and the switches S1 and S2 are closed, so that the final offset voltage can be reduced to a value obtained by dividing by the voltage gain of the offset voltage generated by the difference in the amount of moving electric charges, accompanying the opening and closing of the switches S1 and S2.  The voltage gain is so set, that when a differential input voltage is 0, the output stays in a transition region.
