Abstract: In an optical waveguide device, a rectangle, which uses a filter insertion groove as its diagonal line and uses points on filter insertion grooves adjacent to the above filter insertion groove as its apexes, is assumed as a unit rectangle, and the size of the optical waveguide device is set to an integer multiple of the unit rectangle. In this case, even if filter insertion grooves are formed in a state in which a plurality of the optical waveguide devices are disposed in matrix, the respective optical waveguide devices can be formed in the same shape. Further, the filter insertion grooves formed to the respective optical waveguide devices do not divide portions other than the target portion of other optical waveguide devices. Therefore, the manufacturing processes of the optical waveguide device can be simplified and are suitable for mass production, and manufacturing cost can be suppressed thereby.

Abstract: A movable substrate 20 is supported on a base 10 via first beam portions 22. A movable contact 28 is supported on the movable substrate 20 via a second beam portion 23 which has an elasticity larger than the first beam portions 22.

Abstract: In a flat knitting machine wherein a plurality of knitting locks work on a single needle bed to knit, the consumption of each yarn is measured and compared with the standard yarn length, and the stitch cam adjustment values of the respective knitting locks are corrected. The stitch cam adjustment data is stored for the respective combinations of stitch cams and yarns. Correction is not limited to the stitch cam which knitted the yarn of which consumption was measured. Correction by the same value is also given to the stitch cam adjustment values of other stitch cams relative to the yarn. As a result, for any combination of a stitch cam and a yarn which appears suddenly in the latter half of knitting, the stitch cam adjustment values have been corrected on the basis of the measurement of consumed yarn lengths of other stitch cams, generating no knitting gaps.
