Title: Method and device for suppressing noise
Inventor: SASAKI SEIJI
IPC: G10L25/90
Filed: 2001-08-13
Abstract: PROBLEM TO BE SOLVED: To suppress not only a usual noise such as automobile traveling sound but also the unusual cyclic noise of a fire truck or a police car with small scale memory capacity and computational complexity. SOLUTION: The presence/absence of a noise as a suppression object is detected from a signal converted to a frequency area in an FFT part 11 by a siren sound suppression information setting part 12, and a basic frequency of that noise is extracted and supplied to a siren sound suppressing part 13. In the siren sound suppressing part 13, a siren sound noise is suppressed on the basis of such information. In such a case, in the siren sound suppression information setting part 12, memory capacity in a long-term average spectrum amplitude updating part can be reduced by extracting the basic frequency for each frame interval determined in advance. Further, the output of the siren sound suppressing part 13 is supplied to a usual noise suppressing part 100 and the usual noise is suppressed.

Title: Spiral spring and apparatus using spiral spring
Inventor: TAKAHASHI OSAMU
IPC: F16F1/10
Filed: 2001-08-24
Abstract: PROBLEM TO BE SOLVED: To provide a spiral spring for reducing a control range of torque, and capable of improving durability of a driving part of an apparatus, and the apparatus using this spiral spring. SOLUTION: This spiral spring used as a motive power source of an electronic mechanical clock is composed of an Ni-Ti alloy being a superelastic material. Since the superelastic material is low in an elastic modulus and is wide in a stress constant range at load removing time, an inclination of a torque curve of the spiral spring becomes almost horizontal like data G1. Since the control range of the torque reduces, a control error is little caused, and accuracy of the electronic mechanical clock can be improved. Since a difference between torque T2 just after winding-up and torque T0 required for driving a generator being the driving part is small, large torque is not applied to the driving part more than necessary as conventional torque so that the durability of these driving parts can be improved.
