Abstract: A method for producing an electrode member that configures an electrode body of an all-solid-state battery, including: a slurry preparation step for preparing a mixed material slurry that contains at least a binder, solid electrolyte particles, and a nonaqueous solvent with low polarity; a molding step for molding the mixed material slurry into a desired shape; and a drying step for obtaining a molded body by removing the nonaqueous solvent with low polarity from the mixed material slurry after the molding. Then, the temperature of the mixed material slurry is controlled so as not to cause re-crystallization of the binder, which has been dissolved in the nonaqueous solvent with low polarity, at least until the initiation of the molding step. Consequently, it is possible to stably provide an all-solid-state battery that has low battery resistance, while improving electrode member production efficiency by preventing gelation of a mixed material slurry.

Abstract: A yarn feeding device for a knitting machine comprises a motor for driving a roller from which a yarn is fed out, and a rotatable arm which intermediately stores the yarn fed out from the roller, and the yarn is fed from the arm to a knitting machine body. A torque generator is provided to apply a variable torque to the arm. A yarn speed is obtained from a loop length of a stitch for each knitting needle and a knitting speed calculated on the basis of knitting data used in the knitting machine body. The yarn speed is converted into a torque to be applied to a buffer using a conversion table at each knitting section in a knitting course so as to correct a yarn tension fluctuation caused by the yarn speed, and the torque generator is controlled in accordance with the torque thus obtained. The yarn tension fluctuation is reduced so that high-speed knitting and knitting using a weak yarn can be facilitated.

Abstract: An object of at least one embodiment of the present invention is to stably feed a yarn by suppressing the effect of inertia in a buffer mechanism provided in a yarn feeding path. In at least one embodiment, a yarn feeder of the weft knitting machine feeds a knitting yarn from either of ends of a needle bed through a yarn feeding member to a knitting needle which carries out knitting motion based on knitting data while reciprocating the yarn feeding member in a longitudinal direction of the needle bed. A buffer rod is provided in the feeding path for the knitting yarn. Before the yarn feeding member starts to feed the knitting yarn to the knitting needle. a yarn feed controller carries out control to feed out the yarn to the buffer rod beforehand in a moving direction in which the feeding path is extended and to pull back the yarn stored in the buffer rod in a moving direction in which the feeding path is reduced.

Abstract: An optical wave guide device is manufactured by bonding an optical wave guide to an optical modulator through an upper cladding layer. The optical wave guide includes a glass substrate, a lower cladding layer and cores, and the optical modulator includes elements (heaters), which are disposed on the lower surface of a glass substrate, for modulating the light propagating in the cores, and electrodes and wire bond pads which are disposed on the front surface thereof. The elements are connected to the electrodes via through-holes. With this arrangement, there can be provided an optical waveguide device, in which cores are not degraded in manufacturing processes and elements for modulating the light propagating in the cores are unlikely to be exfoliated.

Abstract: The spacers 3 and 4 and the recess is formed on the supporting substrate 2 to support the upper cladding layer 7. The intermediate surface 22 and 23 lower than the top surface of the spacers 3 and 4 and higher than the inner bottom surface of the recess is formed on the supporting substrate 2. Each of the height between the top surface of the spacers 3 and 4 and the intermediate surfaces 22 and 23, and the height between the intermediate surfaces 22 and 23 and the inner bottom surface of the recess of the second substrate 2 becomes thin compared with the total thickness of the lower cladding layer. Thus, when the resin for the lower cladding layer 9 is cured to shrinkage, the inner stress in the resin is dispersed and the occurrence of the wrinkle 12 and the void decreases.

Abstract: An optical multiplexer/demultiplexer having a high isolation characteristic, a small polarization dependency and capable of being reduced in size is disclosed. An end portion of a core and an end portion of a core are arranged in opposed relation to each other with a thin-film filter interposed therebetween.

The end portion of the core near to the filter is curved in a manner protruded toward the core. The end portion of each of the core and the core far from the filter reaches an end of an optical waveguide, and the end portion of the core far from the filter reaches a side of the optical waveguide.

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.
