A receiver includes a tuner that converts an FM radio broadcast signal into an intermediate frequency signal that has the same frequency as a sound intermediate frequency subcarrier signal when receiving the television broadcast signal and outputs the intermediate frequency signal when receiving the FM radio broadcast signal, a SAW filter passing only an intermediate frequency band of the output of the tuner, a video detector detecting a video signal containing a sound subcarrier signal when receiving the television broadcast signal and detecting a sound subcarrier signal when receiving the FM radio broadcast signal, a VIFAGC circuit making the video signal have a constant amplitude, and an AGC circuit making a sound subcarrier signal output from a band pass filter have a constant amplitude.

Receiver selectively receiving, demodulating and outputting a tv broadcast signal and an FM radio broadcast signal

In a golf club head having a face body, the face body is composed of a hybrid of an amorphous phase layer and a crystal phase layer. The crystal phase layer is disposed on a reverse face side of a face. And, thickness of the face body is 0.5 mm to 5.0 mm, thickness of the amorphous phase layer is, on average in whole area of the face body, more than 50% of the thickness of the face body, and thickness of the crystal phase layer is arranged to be 0.01 mm to 3.0 mm.

Golf club head

A concave portion to which a face body is fitted is formed on a face side of a head main body. A concave groove is formed along an inner peripheral surface of the concave portion as to leave a side wall of a small thickness dimension. A caulking member is press-fitted into the concave groove. The side wall is deformed to the face body by lateral pressure of the caulking member, tightly fitted to the face body, and to hold the face body.

A head body portion comprises a plate-shaped face wail portion of approximately 2 mm to approximately 3.5 mm in thickness and a shaft connecting portion. The face wall portion is provided with weighting projections at four places thereof, toe side upper and lower portions and heel side upper and lower portions of a rear portion thereof.

Head for iron type golf club

The present invention provides an iron golf club head which comprises a core member, a striking face member and a cladding. The core member is made of a metal having a large specific weight, and has an exposed integral sole portion, an integral riser wall portion, and an integral shaft connecting portion. The striking face member is fixed to a front surface of the core riser wall portion, and made of a light metal reinforced by whiskers and/or fibers. The cladding is also made of a light metal, and covers all surfaces of the riser wall portion and the shaft connecting portion except for a surface portion of the riser wall portion on which the striking face member is fixed.
