Title: Method and device for compensating light dispersion
Inventor: KITAJIMA SHIGEKI
IPC: H04B10/07
Filed: 1993-01-27
Abstract: PURPOSE:To simultaneously compensate the group delay characteristics of multiple signals affected by the dispersion of optical fibers by making the inverse of the propagation delay time of a delay optical path almost coincident with the optical frequency interval of multiple optical signals. CONSTITUTION:Concerning the optical signals from plural optical transmitters 1, the central optical frequencies are arranged at almost equal intervals. The optical signals from the respective optical transmitters 1 are synthesized by an optical synthesizing means 2 and turned to the multiple optical signals. Then, a light dispersion compensator 4 is composed of a two-input/two-output photocoupler 41 and a delay optical path 42 which propagation delay time is specified, and an input to the light dispersion compensator 4 is inputted to the first input of the photocoupler 41. An output from the light dispersion compensator 4 is connected with the first output of the photocoupler 41, and the second output and the second input are connected by the delay optical path 42. The inputted multiple optical signals are delayed since one part of them turns around the delay optical path 42, and the group delay characteristics coused by dispersion received during the propagation of optical fibers 3 are compensated. The multiple optical signals, which light dispersion is compensated, are sent to a multiple optical receiver 20.

Abstract: PURPOSE:To cause a required amount of air corresponding to combustion to be supplied in a downstream direction and enable uniform combustion to be performed including at the end part of a wick by a method wherein flame holes to cause an amount air flowed to be gradually increased from the upstream side to the downstream side are provided at red heat portions at both side surfaces of a combustion cylinder. CONSTITUTION:Upon ignition of a wick 1, combustion is carried out with air supplied from a porous plate 4 and flame holes 7 of a rear porous plate 5 and a temperature of flame is increased and a normal combustion condition is attained. At this time, a part of the air flowing from the flame holes 7 is used as premixing air, and air flowing from flame holes 8 is added to complete the combustion. In turn, port diameters of the flame holes 9a-9n arranged at side surfaces 4b and 4c are set to be gradually increased from the upstream side to the downstream side in respect to the combustion at both end portions of a combustion chamber 3, so that at the upstream side the amount of air to be supplied is decreased and so a cooling by air can be suppress. Further, since the amount of air supplied toward the downstream side area can be gradually increased, the requisite air corresponding to the combustion can be supplied and a stable combustion state can be attained.

Abstract: PURPOSE:To prevent generation of cracks in a saw body, by making holes in the saw body and by chamfering the holes and the bases of the saw teeth. CONSTITUTION:Even if diamond chips are attached on the saw teeth 7 of a saw body 6 as cutter blades 8, the bending resistance of the saw teeth 7 is reduced due to circular holes 10 formed in the parts of the saw body 6 which correspond to the saw teeth 7. This bending resistance is balanced with that of the narrow tooth bases 9 of the saw body 6 and thus the bending resistance of various parts of the saw body 6 are made uniform. Furthermore, by chamfering the peripheries of the tooth bases 9 and holes 10, the corner sections to which stress concentrates are removed from both tooth bases 9 and holes 10, and the stress is completely dispersed. As a result, the band saw can be used till its practical life comes to the end.
