  • Patent number: 7491270
    Abstract: A heat shielding member 20 that thermally shields the periphery of a single crystal 16 used in a Czochralski single crystal pulling device that pulls the single crystal 16 from a melt 15 that is collected in a crucible 10 is disclosed. The heat shielding member 20 is provided with an approximately cylindrical main body portion 21 arranged so as to surround the single crystal 16, with a lower end portion thereof extending to the vicinity of the melt 15, and an approximately annular bottom plate portion 22 that extends in the diameter direction from the bottom end portion of the main body portion 21 to cover the melt. The bottom plate portion 22 is attached to the main body portion 21 in the state of being severed in the circumferential direction at at least one location. With this constitution it is possible to provide a heat shielding member with superior durability and a single crystal pulling device that employs the heat shielding member.

  • Publication number: 20080190737
    Abstract: Rather than simply changing a component or module to be installed, a conveyance speed of a conveyance means for conveying a workpiece is modified in response to the specifications of a product when a product with specifications modified in part from common specifications of mass produced products is added to the mass produced products. Furthermore, a condition wherein the speed of the conveyance means is modified in accordance with specifications is displayed in real time such that a worker can identify the condition.

  • Publication number: 20070265839
    Abstract: A method for changing reproduction speed of speech sound, includes the steps of: storing an input sound signal in a buffer; leaving a sound signal from the buffer as it is or extending the sound signal from the buffer in a sound section where a power of the input sound signal exceeds a threshold value; leaving the sound signal from the buffer as it is, compressing the sound signal from the buffer, or extending the sound signal from the buffer, in a no-sound section, so that the reproduction speed of speech sound is changed; wherein a speech head protection section is set prior to the sound section being set to be a storing amount of the buffer limited by a designated limited value; and compression or deletion of the sound signal is adjusted by a compression ratio or prevented if there is the sound section in the speech head protection section, so that speech head protection is performed.

  • Publication number: 20070180675
    Abstract: Mounting of an axle module to a chassis frame is carried out in vertically normal orientation (not in an inverted state). In the process, no heavy-duty equipment or steps are required to hoist chassis frames in the air and turn them upside down. The ceiling space above production lines is reduced. A method and a device are provided for mounting axle modules that are suitable for supplying to a rotary assembly stand. An axle module is transported to a first support stand in normal orientation and a chassis frame is transported to a second support stand also in normal orientation. By lifting the first support stand its mounting ends are aligned with the mounting brackets of the chassis frame. Cylinder means and hovering means are used for lifting.

  • Patent number: 7072830
    Abstract: An audio coder that improves audio quality by reducing a quantization error. When a code corresponding to a sampled value of an audio signal is determined, a candidate code storage section stores all combinations of candidate codes in a neighborhood interval of the sampled value. A local decoder generates reproduced signals by decoding the codes stored in the candidate code storage section. An error evaluation section calculates, for each candidate code, a sum of squares of differentials between input sampled values and reproduced signals, detects a combination of candidate codes by which a smallest sum is obtained, that is to say, which minimizes a quantization error, and outputs a code included in the detected combination of candidate codes.

  • Patent number: 7067768
    Abstract: A motor-driven welding gun has a servomotor for displacing a movable electrode tip toward and away from a fixed electrode tip. The servomotor has a motor housing with a copper pipe which is inserted therein when the motor housing is cast. The copper pipe provides a coolant passage in the motor housing for supplying a coolant therethrough. When the coolant passage is supplied with the coolant, the motor housing is forcibly cooled, reducing the amount of heat generated by the servomotor.

  • Patent number: 7039903
    Abstract: The collating device includes the Formant estimation section that estimates feature amount data that represents a time-based change in frequencies of first and second Formants from voice data input through the microphone. The difference computing section calculates a difference between some reference feature amount data and the feature amount data as the feature-amount difference data. This feature-amount difference data is stored in a database. The feature-amount difference data corresponding to voice data input upon collation is collated with the feature-amount difference data registered in the database, and the result is output.

  • Publication number: 20050167137
    Abstract: An electronic part which can be miniaturized is provided. A bottom surface of a substrate of an electronic element is positioned on the same virtual plane of an upper surface of a sidewall portion of a case body, and a seal material is covered thereon. Accordingly, a gap between the seal material and the bottom surface of the electronic element is not formed, and thus the electronic part can easily be made thin. Also, since the seal material is formed by a resin, even when positions of the bottom surface of the substrate and an upper surface of the sidewall portion are deviated, the deviation can be easily absorbed.
