Title: Reel
Inventor: OKAWA SADAO
IPC: B65H75/22
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To prevent any increase in the cost of equipment as well as to aim at a reduction in the number of metal molds by making the best use of a plastic reel by forming a pair of split reels, whose opposed surfaces are symmetrical, with the same metal mold, and combining them together. SOLUTION: Both split reels 10 and 20 are opposed after making two opposed ends of a hub part 12 facing with each other, thereby joining both of them together. In this state intact, a claw piece 16 of the split reel 10 catches an arm 25A of the split reel 20, and then another claw piece 26 of this split reel 20 seizes hold of an arm 15D of the split reel 10. In addition, a projection strap 23B of a large diametral hub part 23 of the split reel 20 is positioned and stored in a recess groove 13A, and a closed airspace is made up at an interval between this recess groove 13A and an incline 23X of the projection strap 23B. Further, in this state too, a claw projection 17 is fitted in a cavity part 28 of the split reel 20, and further this claw projection 27 is fitted in another cavity part 18 of the split reel 10.  Since both of them are integrally worked by means of ultrasonic joining in this state intact, fused resin is fused into space, making them integratable in this way.

Abstract: PURPOSE:To improve wavelength characteristics of oscillation and oscillation efficiency, by constituting a lambda/4-shift DFB laser structure wherein a large- reflection region composed of corrugation having a large coupling coefficient is arranged so as to connect with a light waveguide on one end surface side. CONSTITUTION:The period of corrugation in a large-reflection region 9 is equal to the period in a main oscillation region 10, but the depth is very deep, which is selected as 800Angstrom  in the large-reflection region, for example, in the case where the depth in the main oscillation region 10 is 200Angstrom . In this example, the coupling coefficients in the main oscillator region and in the high-reflection region are 30cm<-1> and 200cm<-1>, respectively. When the length of the main oscillation region L is made as 300Angstrom , and that of the large-reflection region l is made as 100Angstrom , the light output efficiency is 0.15mV/mA in the case of a conventional structure where not provided with the high reflection region, but the data of 0.3mW/mA is obtained by this example. A figure shows that a lambda/4-shift is symmetrically formed on the both sides with respect to a center point A in the main oscillation region 10. But any problem does not occur even if the high-reflection region 9 extends to the left side and the shallow corrugation region on the right side of the point A is made narrow.
