IPC: G02B6/12
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To make it possible to incorporate a large number of wavelengths within a passing band by determining a propagation constant difference, a coupling coefficient, and coupling length by satisfying the conditions that a curve connecting a point moving on x-y coordinates according toe variations in wavelength be in tangent to an ellipse arc of a specific equation expressing a cross state. SOLUTION: A coupling coefficient between a 1st and a 2nd waveguide paths is expressed by κ(λ), a function of wavelength λ, and x and y are defined as the equations I. In this case, a propagation constant difference Δ(λ), a coupling coefficient κ(λ), and a coupling length L are determined so as to satisfy the conditions that a cur e drawn according to variations in the wavelength λon x-y coordinates based on the equations I is tangent to an ellipse expressed by the equation II at a point [x(λ1), y(λ1)] and intercrosses a circle expressed by the equation III at a point [x(λ2), y(λ2)].  Further, in order to produce a propagation constant difference Δ(λ) between individual optical waveguides, a predetermined part of each optical waveguide may be increased in the refractive index or increased in the width or provided with a heater to increase the refractive index.

Abstract: PURPOSE: To synchronize a sheet and an impeller positively by a mechanism wherein the entry of the sheet is detected and the impeller is accelerated in a synchronizing device for the impeller used in the case when sheets, such as, paper money, etc. are lined up.  
     CONSTITUTION: When a sheet 4 is transmitted by means of a feed roller 12 in the width direction, a cam 13 is moved due to friction with the sheet 4. Since the cam 13 is moved, a pawl piece 17 shifts the projection portions 8 of a ratchet 7 in the direction that the projection portions are pushed through a link 14 and a lever 15. When timing between the delivery of the sheet 4 by means of the feed roller 12 and the reception of the sheet 4 by means of an impeller 1 does not agree at that time, one blade 3 and a guide plate 9 slip. Since the slippage also takes place at the projection portions 8, the projection portions 8 are thrusted by the quick transfer of the pawl piece 17, and the one blade 3 and the guide plate 9 are corrected on a surface. The sheet 4 housed in the impeller 1 is stored in a receiving plate 10.

Abstract: PURPOSE:To completely prevent processing from being inversed by providing the titled device with memories for stacking starting factors in the order of start, registering factors in the order of start and transferring the starting factors in the registered order on the basis of a user task request. CONSTITUTION:Necessary memories 1-l for stacking starting factors are sufficiently prepared and controlled by a registering pointer and a reading pointer. At the time of generating a starting factor, the factor is registered in the memory and the pointer is counted up. When a user task 7 is started, factor reading is requested by a new instruction, the factor is extracted from the memory pointed out by the pointer and transferred to a user task. If a starting factor reading macro is generated when the registering pointer coincides with the reading pointer, '0', (specific code) is transferred as a starting factor and the disappearance of the factor is informed to the user task. In said constitution, the inverse of processing in the user task can be completely suppressed, and even if plural same starting factors exist, the processing is not missed.
