Latest Patents

One of Hariguchi's latest patents is a vibration absorber for a racket. This invention involves a mass that is indirectly supported by a visco-elastic member arranged within the grip or the yoke of the racket. The design allows for the resonant swing of the interface to cause deformation of the visco-elastic member, facilitating thermal diffusion of vibration energy. The visco-elastic member is sandwiched between two elongated leaf springs, which are strategically mounted to dampen vibrations in a specified frequency range, thus enhancing the performance of various types of rackets.

Another significant patent is a method for producing a wood-type golf club head. This innovation utilizes a thermoplastic synthetic resin core, which serves as a substitute for the conventional rubber air bag. This method ensures stable and reliable shaping of a fiber-reinforced plastic (FRP) shell, even at room temperature. The process avoids air void generation and layer separation, resulting in a beautifully molded shell.
