  • Patent number: 4687205
    Abstract: An iron type golf club head comprising a composite material of light metal or synthetic resin containing silicon carbide whiskers at 2 to 80% by volume and occupying 20% or more by volume of the body of the club head. The club head can be 10 to 60% lighter than a club head made entirely of steel with the same configuration and size, while the moment of inertia is approximately the same. Weight metal inserts having a specific gravity greater than steel can also be embedded in the club head.

  • Patent number: 4543827
    Abstract: A method for measuring the physical properties of material comprising the steps of producing a tone burst wave by a tone burst wave oscillator, radiating acoustic energy of the tone burst wave onto an object to be measured to cause vibrations therein, detecting the vibrations as a waveform of an alternating wave at a vibration receiver, obtaining a gradient of a line which connects peaks in a first transitional region of the waveform from which can be determined the physical properties, in particular the energy transfer characteristics and/or restitution coefficient of the object.
