  • Patent number: 7714474
    Abstract: In a stator core having “N” slots, a tooth-width centerline of a linear yoke and a first extension line extended horizontally from a center of rotary shaft toward the linear yoke form a first angle. Assume there are first point on the first extension line at a first distance from the center, a second extension line drawn at a second distance horizontally from the center toward the linear yoke and extended vertically toward arc-shaped yokes, and a third extension line drawn from the center toward teeth ends of the linear yokes with angle “K”. The second and third extension line intersect at a second point. A line between the first and second points intersects with the first extension line, thereby forming the first angle. In this structure, 0<a<b, and (360/2N?60/2N)°<K<(360/2N+60/2N)° are established, where “a”, “b” are the first and the second distances respectively.

  • Patent number: 6577587
    Abstract: A turntable device includes a disc base on the circumference thereof, and the disc base has a hardness more than a given level. The surface of the disc base is roughened at a given level in order to prevent the disc from slipping and adhesion to the disc base. The disc base can compensate surface wobble caused by the disc base. A manufacturing method of the turntable device includes the steps of: a) dripping liquid resin mixed with fine particles on the circumference of the turntable; and b) hardening the resin to form the disc base. The turntable device is good for e.g. CD players, optical disc driving apparatuses.

  • Patent number: 6205420
    Abstract: An analysis processor applies an analysis process to input speech data thereby to obtain block lengths for respective attributes of voiced sound, voiceless sound and silence. A block data splitter splits the input speech data into blocks having the block lengths dependent on the respective attributes. A block data memory sequentially stores speech data split by the block data splitter as block speech data and the block lengths. A connection data generator generates connection data for connecting the adjacent block speech data each other at every moment by using the block speech data. A connection data storing portion sequentially stores the connection data. A connection order generator generates block connection order of the block speech data and the connection data at every moment according to at least the block lengths output sequentially from the block data storing portion and extension scaling factors in time for the respective attributes.

  • Patent number: 5062926
    Abstract: The solvent recovery apparatus includes an adsorption tower having a gas adsorption element; a gas supply pipe for supplying a solvent-containing gas to the adsorption tower; a steam supply pipe for supplying steam to the adsorption tower; and a solvent recovery pipe for recovering a removed solvent. Disposed at the solvent recovery pipe are a condenser and a specific-gravity separating unit for recovering a liquefield solvent. An intermediate liquid storing unit is disposed between the condenser and the specific-gravity separating unit, and has a valve adapted to be automatically opened when the intermediate liquid storing unit stores a liquid of which amount exceeds a preset value, so that the liquid flows into the specific-gravity separating unit. With this solvent recovery apparatus, organic solvent gas or flon gas may be recovered.
