  • Patent number: 7609843
    Abstract: The present invention provides a sound collector preferably applicable to an acoustic analysis with a high degree of accuracy and includes a sound collection hood having an opening at the front end and a sound reflective inner wall shaped like a rotating surface having a focus behind the opening at least provided on the opening side, thus forming an inner space, a microphone placed inside the sound collection hood with at least a sound receiving face oriented forward for receiving a sound wave entering the sound collection hood and an acoustical absorbent body formed in front of the sound receiving face so as to form an incident path for sound to enter the sound receiving face and in a shape surrounding the incident path.
    Type: Grant

  • Patent number: 7352875
    Abstract: The present invention provides a speaker apparatus which has a simple structure and a high directivity and which can emit sound. The speaker apparatus includes a hood having an opening at a front end with a sound reflecting inner wall shaped like a rotating surface and provided at least on the opening side, the sound reflecting inner wall having a focus behind the opening, the hood being formed with an internal space, and a sound processing section having a vibrating surface and a sound emitting circuit both provided in the hood, the sound emitting circuit vibrating the vibrating surface. Consequently, the diameter of the vibrating surface of the sound processing section, which diameter determines the spread, outside the hood, of a sound emitted by the speaker apparatus, can be considered to be larger than its actual dimension.

  • Patent number: 5798459
    Abstract: The present invention relates to a subject identification method which is adapted for performing an examination as to whether any change exists on an subject, or adapted for performing an estimation of a degree of the change on the subject. It is an aim that the examination and the estimation are performed with great accuracy. Residual signals are evaluated by means of letting an inverse filter interact with a standard and samples which may be out of the standard, so that a plurality of statistical variables are extracted, thereby testing or estimating as to whether a statistical significant difference exists between those two statistical variable groups.

  • Patent number: 5476730
    Abstract: In an air cell a current collector is so disposed between a cathode and an anode that it is in contact with the cathode. The air cell can thus be compact and lightweight and yet is capable of generating a high power output under low internal resistance. Furthermore, the cathode has a plurality of spaced-apart sections or at least one through-hole to facilitate the release of hydrogen.
