Title: Automatic compensation method and device for primary polarization mode dispersion
Inventor: FISHMAN DANIEL A
IPC: H04B10/18
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a device which can automatically fit a primary polarization mode dispersion(PMD) level by producing a control signal proportional to the total value of the differential optical time delay of the optical signal occurring at the output part of a variable birefringence element via an optical signal analyzer and controlling the differential time delay value, which is generated for the control of selecting a specific orthogonal polarization state by means of the control signal. SOLUTION: Automatic fitting is attained to a PMD level, via the differential time delay of a variable differential time delay line 50 and the supply of a feedback signal, that controls the polarization transformation of a polarization transformer 30. Some of signals which are outputted from a compensation device 25 are supplied to a path 87 which reaches a fast photodetection device 55 via an optical tap 85, and other signals are supplied to a path 86 reaching a receiver 90. The device 55 converts the fast digital information signal modulated on an optical carrier signal into an electric signal. The electric signal is amplified by an amplifier 60 and sent to an electrical distortion analyzer 70 which measures the distortion of the amplified optical current and coverts the amplified result into a voltage that is proportional to the measured distortion.

Abstract: PURPOSE:To perform coating with a uniform thickness by providing non-contact sensors which detect the position of any region moving back and forth in synchronization with a coating device, position/speed conversion device of a crank drive motor and a crank drive motor control device. CONSTITUTION:Non-contact sensors S are arranged on a rocking orbit for a parallel link 3A, and data on the position of moving coating devices 2A, 2B is output. For example, a motor 6 is driven at high rotation speed from a left reversing position P0 to a speed acceleration end position P1 and thereby the coating devices 2A, 2B are driven at accelerated speed. If the coating devices 2A, 2B reach the speed acceleration end position P1, a paint valve 12 opens to initiate coating. Next, rotation speed of the motor 6 slows down upto a position where parallel links 3A, 3B become vertical during a period when the devices are reaching a speed reduction start position P2 and then ascend at this position P6 where the rotating speed has dropped. If the devices arrive at the speed reduction start position P2, a paint valve 12 is closed and the rotating speed is maintained at high level until the devices arrive at a right reversing position P7 and a speed acceleration end position P3. When the coating devices move at uniform speed, paint is supplied at constant flow to perform painting.

Title: Photocurrent transformer with core
Inventor: TANAKA NAOKI
IPC: G01R15/24
Filed: 1990-09-28
Abstract: PURPOSE:To enable accurate measurement of a current ranging from a small current to a large one without enlargement of a gap distance by winding a closed-loop-shaped coil on a core so as to cancel a magnetic flux due to a through conductor. CONSTITUTION:A photosensor 2 is inserted inside a gap of a core 1 and a current flowing through a through conductor 3 is thereby caught as a change in a magnetic field and measured. On the occasion, a loop-shaped coil 4 is wound round on the outer periphery of the core 1. The magnetic field generated by the current flowing through the conductor 3 generates a magnetic flux in the same direction, and concurrently such a secondary current as to cancel the magnetic flux flows through the coil 4. When a coefficient of coupling is 100% on the occasion, the magnetic field is canceled and dose not occur. However, it is lower than this rate inevitably due to a leakage flux and others and the magnetic flux due to the difference occurs. By detecting this magnetic flux, saturation of the core is prevented without enlargement of a gap distance, deterioration of characteristics due to the effect of another magnetic field and others is avoided, and the current ranging from a small current to a large one can be measured.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of burrs by preliminarily generating a round edge on the rear side of the punched hole of a material to be worked, executing punching from the surface and generating the round edge on both surface and back faces of the periphery of the hole. SOLUTION: In a 1st punching die 1, a work W is pressurized with a punch tip 15 and die 31. The round edge DL is generated on the underside of the work W with the projecting part 31P of the die 31. A guide hole GH is worked on the upside of the work W with the guide working part 13 of the punch tip 15. The work W is positioned to the 2nd punching die 41. By pressurizing the punch head 23 of the punching die 41, the work W is punched with the die 45 and punch tip 15. The round edge DL is formed on the peripheral edge at the lower end of the punched hole PH and a small round edge DL is formed on the peripheral edge at the upper end of the hole PH by punching. Because the round edges DL are presented on the peripheral edges of the upper and lower sides of the work W, the burrs are not generated at the time of punching.  Even when the axial centers of the 2nd punching die 41 and the work W are shifted, the projecting part 13A of the punch tip 15 is engaged with the guide hole GH and misalignment is corrected.
