Title: Manufacture of optical fiber resonance loop
Inventor: SUZUKI FUMIO
IPC: G01C19/72
Filed: 1990-05-24
Abstract: PURPOSE:To manufacture the resonance loop with superior optical characteristics by manufacturing the resonance loop under the best constitution where finesse determining the quality of the resonance loop is determined. CONSTITUTION:A fiber loop is formed while the loop length is varied by expanding or contracting the fiber loop of a resonance point obtained by making wavelength-modulted light incident on the fiber loop and monitoring a light output from the fiber loop. Therefore, optical fibers which form the fiber loop can be connected while optical characteristics are monitored to make a connection with extremely low loss, thereby manufacturing the resonance loop with superior optical characteristics. Further, the optical characteristics can be monitored, so the coupling ratio of an optical fiber coupler can be adjusted to the best value and the resonance loop with the superior optical characteristics can be manufactured.

Title: Wait control circuit
Inventor: KANEHARA TETSUO
IPC: G06F13/42
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To insert a wait without causing command setting width to affect the output timing of a wait request. SOLUTION: While a cycle is started and a command is being outputted, a state transition circuit makes a command counter 12 count up. Command counter compare 13 compares the output of the command counter 12 with a command width set value and generates a command time-out output when they become equal to each other. The state transition circuit checks the level of the output of a synchronizing circuit 16 and makes the cycle wait in the same state when the level is '0'. When the level '1', state transition is caused and the wait counter 14 is made to count. The wait counter 14 when reaching IOCHRDY='0' returns to the last state, and the cycle is made to wait and extended until IOCHRDY='1'. While the wait counter 14 is counting, the wait counter compare 15 generates a wait time-out output when reaching a wait set value and the state transition circuit finishes the cycle.

IPC: G11B7/125
Filed: 1989-05-29
Abstract: PURPOSE:To prevent the chromatic aberration of a laser diode from being generated by controlling laser power by changing the duty of a high frequency superimpose pulse supplied from a high frequency supplying device. CONSTITUTION:By using a duty controller composed of a variable delay circuit 2, AND element 3, OR element 4 and switch element 5, the duty of the high frequency superimpose pulse is changed and the laser power is controlled at the time of reproducing. Accordingly, reproducing power and recording power is not obtained by the change of a current value and a current is set to a fixed value. Thus, at the time of reproducing, the power is not affected by a lower limit value for operating the laser diode and further, the chromatic aberration caused by a change in each wavelength of the laser diode does not go to be a problem.

Inventor: MARCUSE DIETRICH
IPC: G02F1/125
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To modulate an optical signal by changing the power of elastic surface wave according to a 2nd signal to modulate a signal propagated to a single mode part for output from a multimode area, that is, the attenuated optical signal propagated in an even transmitting mode. SOLUTION: A multi-mode waveguide 15 is connected between a single mode input planer waveguide part 100 and an output planer waveguide part 110, and propagates the optical signal from the input part 100 to the output 110 in the 1st even transmitting mode through a multi-mode waveguide part 105. By turning the elastic surface wave to the waveguide 105, optical power is converted to an odd transmitting mode so as to attenuate the optical signal propagated in the even transmitting mode. Attenuating amount depends on the amplitude of the power of the elastic surface wave mutually acting with the waveguide 105. Therefore, by changing the amplitude of the 2nd signal, the power of the elastic surface wave is changed and the optical signal is modulated according to the 2nd signal.

Title: Lock-on method in automatic gauge controller
Inventor: NIIHORI TOSHIAKI
IPC: B21B37/62
Filed: 1978-11-06
Abstract: PURPOSE: To make high accurate the lock-on, by using the outlet side gaugemeter as the reference gauge detector for the period of lock-on.  
     CONSTITUTION: At starting the rolling work, RY 48 is being put OFF, and the output of the rolling reduction control output system 44 depending on the outlet side gauge deviation is being produced for the screw down system. At this moment, the output of the rolling reduction control output system 46 is being inputted into the lock-on mechanism 47. The rolling reduction control output system 44 operates the screw down device to open or close until the outlet side deviation makes zero; when the deviation signal h ox  for the outlet side gauge makes zero, the zero detector 49 causes the lock-on mechanism 47 to memorize the output of the rolling reduction control output system 46 at that moment according to the lock-on command. As a result, the output of the lock-on mechanism 47 becomes equal to the output of the rolling reduction control output system 46, and the output of 47 becomes the input of the system 46, so that the output of the rolling reduction control output system 46 makes zero. Meantime, RY 48 is put ON, and the rolling reduction control output system 44 is disconnected from the screw down system, and the rolling reduction control output system 46 is connected to the screw down system. Hereafter, the gaugemeter system AGC of this invention starts the operation.
