IPC: G10L15/00
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for voice recognition with which a recognition rate is improved in periodic noise environment. SOLUTION: In a voice recognition method in noisy environment, a cutoff frequency determining section 30 and a high pass filter 40 which is controlled by the section 30 are provided in the latter stage of a voice detection section 20.

Title: Scanning optical device and method for mounting elastic member and lid part of the device
Inventor: TOMITA KENICHI
IPC: G02B26/10
Filed: 2000-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent the contamination of an optical component due to a volatile matter generated in a device by combining an elastic member with a lid part partially to significantly reduce the amount of adhesive used for the combination. SOLUTION: The elastic member 10 is stuck on the rear side surface of the lid part 9 by a double faced adhesive tape 11 shown by hatching, and the double faced adhesive tape 11 is stuck only at the central portion of the lid part 9. Thereby, a cost reduction can be realized because the area of the double faced adhesive tape 11 can be sharply made small. Then, when the lid part 9 is removed from an optical box 1, the elastic member 10 departs with the lid part 9, and does not deviate from the lid part 9. Although an organic solvent is usually included in the double faced adhesive tape 11 as an adhesion component and there is such problems that a volatilizing organic solvent corrodes plastic parts, or pollutes the optical component, the amount of volatilizing organic solvent can be reduced by reducing the adhesion area of the double faced adhesive tape 11.
