Title: Tennis racket
Inventor: KANEMITSU YUMI
IPC: A63B49/08
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To restrain vibrations of the whole racket to thereby restrain the shock and vibrations transmitted to a player's hand by setting an attenuation ratio of out-surface primary and secondary inherent vibrations to be in a specified range. SOLUTION: A racket whose out-surface primary and secondary attenuation ratios are 0.016 or more and 0.008 or more respectively renders a small acceleration applied to a player's hand when a ball is hitted by the racket and making the attenuation time of acceleration small, thereby reducing the shock applied to the racket and also effectively attenuating the vibrations. On the other hand, in the case of a racket whose out-surface primary and secondary attenuation ratios are 0.016 or less and 0.008 or less, the acceleration transmitted to the player's hand at the time of hitting the ball is made large and the attenuation time of the acceleration is made large, thereby increasing the shock applied to the racket and also requiring much time to attenuate the vibrations.

Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To allow the synthesizer to have provision for a high-speed frequency switching by improving the instability due to external factors, such as a carrier noise ratio C/N0 resulting from a noise component in the vicinity of a carrier, vibration and electromagnetic disturbances. SOLUTION: A DDS(direct digital synthesizer) 3 frequency-divides a reference signal outputted from a reference oscillator 4. A ripple counter 5 frequency- divides an output of the DDS 3 and generates harmonics which are multiple of M of the divided frequency. A 1st BPF(band-pass filter) 6 extracts a desired harmonic component of the M multiple harmonics. A mixer 9 mixes an output of the 1st BPF 6 with an output of a multiplier 8. A 2nd BPF 11 extracts a desired frequency (L) from the mixer 9. Here a control section 1 controls the DDS 3, the ripple counter 5, a 1st control voltage generator 7, and a 2nd control voltage generator 10 based on a value stored in a memory 2.
