Title: Forming method of bragg reflection grating in waveguide and bragg reflection grating thereof formed by same method
Inventor: ROURKE HOWARD NEIL
IPC: G02B6/124
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for avoiding undesired phase discontinuity between adjacent sections of a long Bragg grating written in an optical fiber for every section and the Bragg reflection grating formed by the method. SOLUTION: A mask having a write part and an adjusting part are sued. Each adjusting part is the replica of a part of the write parts of the adjacent mask. Light having the same wavelength as the wavelength used for writing of a section excites stronger luminescence than that of the area in which the rise of refractive index occurs in the area of a waveguide in which the increase of the refractive index induced by irradiation is not occurred. Consequently, in the light directed to the previous part in which the grating is written through the adjusting part of the mask, the intensity of the luminescent light propagating to the end of the waveguide is changed depending upon the overlapping degree of the bright fringe generated by mask and the irradiated part corresponding to the written Bragg grating.  The fine adjustment is performed for acquiring the intensity corresponding to the superposition on a desired level before the start of writing by the mask.

Filed: 1978-10-23
Abstract: PURPOSE: To realize detection for the deterioration due to the minute defect, the water absorption of the anticorrosive layer and other factors by mrasuring the tan δ of the cable anticorrosive layer by means of the high frequency power source.  
     CONSTITUTION: The system comprises cable covering layer 1, coil L 2  which is connected to layer 1 at one end with the other end earthed, dielectric loss tangent measuring instrument 4 containing the terminal which connects the non-grounded side of L 2 , and high frequency power source 5 which is applied to the high voltage side of instrument 4 respectively.

Title: Response system for multipoint communication
Inventor: TAKEDA YOSHIO
IPC: H04Q9/00
Filed: 1990-05-21
Abstract: PURPOSE:To suppress the time for responses from plural slave stations connected to a host station at a minimum by omitting a polling process to be exchanged between the host station and the slave stations each time, calling the plural slave stations from the host station in a latch and making the response within specified time set in advance for each slave station. CONSTITUTION:Normally, a transmission/reception part 2 is activated by activating polling from a batch call control part 3 of a host station 1 and the control signals are transmitted to transmission/reception parts 20 of slave stations 11-1n. The transmission/reception part 20 detects a set signal (a) from the received signal so as to activate the response timing to the host station 1 and inputs the signal to a timer 21. Therefore, the value of timing for transmitting the response selected in advance is set to the timer 21 by a station setting part 22, and the count of the timer 21 is started. On the other hand, when the batch call from the host station 1 is disabled by any cause, the individual calling operation of the slave station is executed by using an individual call control part 5 and a retrial time number designation part 4. Thus, the time for the responses from the plural slave stations connected to the host station can be shortened to the minimum.

Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To improve power conversion efficiency by compensating, for the amount of discharge to be discharged while a charging electric charge of inverse polarity that flows in when a main switching element is off, is discharged during an operation pause period for a capacitor that starts a control transistor that turns off the main switching element and making an overcurrent limit value nearly equal as in a heavy load when reducing a switching frequency in a light load in an RCC(ringing choke converter) type switching power supply.
