  • Publication number: 20230046763
    Abstract: A speech recognition apparatus (2000) includes a first model (10) and a second model (20). The first model (10) is learned by training data with an audio frame as input data, and with, as correct answer data, compressed character string data acquired by encoding character string data represented by the audio frame. The second model (20) is a learned decoder (44) acquired by learning an autoencoder (40) being constituted of an encoder (42) converting input character string data into compressed character string data, and the decoder (44) converting, into character string data, the compressed character string data output from the encoder. The speech recognition apparatus (2000) inputs an audio frame to the first model (10), inputs, to the second model (20), compressed character string data output from the first model (10), and thereby generates character string data corresponding to the audio frame.

  • Patent number: 7309197
    Abstract: An internal gear shaving machine 1 which brings a shaving cutter 3 and an internal gear held by a workpiece chuck 2 into engagement with a crossed axes angle, and subjects the tooth flanks of the internal gear to final machining while it rotationally drives at least one of the shaving cutter 3 and the workpiece chuck 2. The workpiece chuck 2 and shaving cutter 3 are supported movably toward and away from each other in a vertical direction with the workpiece chuck 2 higher and supported movably in the horizontal direction relative to each other. The workpiece chuck 3 is constituted to hold the outer circumferential surface of the internal gear with the axis of rotation of the internal gear oriented in a up-down direction so that shavings produced during processing by the shaving cutter can fall downwardly from the internal gear.

  • Patent number: 5615982
    Abstract: A gear finishing apparatus having a construction in which a support gear supported by a finishing wheel holding section can support and fix a plurality of finishing wheels in parallel, wherein a finishing wheel holding section makes it possible to move an operating portion for holding and rotating the finishing wheel in a direction parallel to the axis of the finishing wheel and to fix it at predetermined positions within the extent of the movement. If the plurality of finishing wheels are attached to the support gear and the positions thereof are adjusted in advance, a new finishing wheel in an adjusted position can be brought into a processing position by moving and fixing the operating portion of the finishing wheel holding section when one of the attached finishing wheels is worn out, thereby obtaining a rapid and continuous finish processing. Further, if different kinds of finishing wheels are attached in advance, the time required for finishing different kinds of gears to be processed can be reduced.

  • Patent number: 4971488
    Abstract: A first table (1) slidable leftwards and rightwards of a gear finishing machine and a second table (2) slidable forwards and rearwards of the machine are disposed in an overlapped relationship such that one of the tables is mounted on the top of the other table. Of these tables, the upper table is guided by a horizontal guide member (3) which is adapted to be rotated to any desired angular position and to be clamped at such position. A feed motor (5) drives the first table to slide.For sliding the table assembly along a diagonal direction, the angular position of the guide member is adjusted so that it extends along such direction.A horizontal stability of the table assembly is secured without employing a conventional parallel link mechanism. The table assembly is driven to slide so as to pass the center of machine so that an accuracy of gear finishing is assured.
