摘要:
This invention provides a golf club head including a plurality of score lines on the face. The golf club head includes a plurality of striations formed on the face and extending from a toe side to a heel side. A depth Dp of each striation satisfies 10 μm≦Dp≦40 μm. A cross-sectional shape of each striation is an isosceles trapezoid having an upper base at the face side and a lower base at the back side of the golf club head. The upper base and lower base satisfy the upper base>the lower base. A width Pb of the bottom portion of each protrusion formed between the striations and a width Wb of the lower base satisfy Pb

This invention provides a golf club head including a plurality of score lines on a face. In the golf club head according to this invention, the angle between each side surface of the score lines and the face is 48° or more. Edges of the score lines are formed to be positioned within a second virtual circle with a radius of 0.011 inches, the second virtual circle being concentric with a first virtual circle which internally touches the side surface of the score line and the face with a radius of 0.010 inches.

The present invention provides methods for identifying or assessing probabilities for developing an abnormal condition in subject and for the recurrence of the abnormal condition in the subject after receiving treatment. The method comprises determining the methylation status of at least one gene in the subject and comparing this methylation status to normal methylation status. Differences between the methylation status of the one or more genes is indicative of the subject developing an abnormal condition or for the recurrence of the abnormal conditions after receiving treatment.

According to this invention, there is provided a method of manufacturing a golf cub head having a plurality of score lines on the face. The method of this invention includes the first forming step of forming grooves for the score lines on the face, and the second forming step of forming notches uniformly along the longitudinal direction of the grooves by cutting into the edges of the grooves formed in the first forming step, the notches having first side surfaces leading to the face and second side surfaces leading to the first side surfaces and side surfaces of the grooves.

According to this invention, there is provided a method of manufacturing a golf cub head having a plurality of score lines on the face. The method of this invention includes the first forming step of forming grooves for the score lines on the face, and the second forming step of forming flat surfaces inclined with respect to the face by cutting into the edges of the grooves formed in the first forming step.

A copying apparatus provided with a light-attenuating filter used for controlling copying conditions. The light-attenuating filter is formed of a nontransparent member in which a multiplicity of small holes or small-width slits are provided. In setting the printing conditions for the copying apparatus, a film development-evaluating film with an evaluating latent image recorded thereon is developed, the image on the evaluating film developed is photometrically measured and printed on a paper, the printed paper is developed, and the density of a print obtained by development is measured so as to set the printing conditions. To photometrically measure the print, a punched hole provided in the paper is detected to photometrically measure a central portion of the image plane.

A guide drum comprises a stationary drum having a tape guide for guiding a magnetic tape along a predetermined tape path and a rotary drum rotatably provided with respect to the stationary drum. The rotary drum has at least one magnetic head for recording and/or reproducing a signal on and/or from the magnetic tape which is wrapped spirally around an outer peripheral surface of the guide drum over a predetermined angular range. The guide drum comprises first and second tapered parts which are formed with reference to a reference position having a specific height from a lower edge of the rotary drum. A diameter of an outer peripheral surface of the first tapered part gradually decreases toward the stationary drum, and a diameter of an outer peripheral surface of the second tapered part gradually decreases in a direction away from the stationary drum.

A position control apparatus for controlling positions of rotary heads with respect to a recording medium, comprises a pulse generating circuit and a head displacing mechanism. A rotary body is mounted with the rotary heads, and two or more rotary heads simultaneously scan over the recording medium at one time. The pulse generating circuit is responsive to a rotation detection pulse signal which is in phase with a rotation of the rotary body, and generates a pulse signal having a phase and pulse width essentially equal to a recording or reproducing time period in which one corresponding rotary head among the rotary heads records or reproduces a signal on or from the recording medium, with respect to each of the rotary heads. The displacing mechanism is provided in correspondence with each of the rotary heads, and separates from a recording surface of the recording medium rotary heads excluding one rotary head which is to carry out a recording or reproduction during essentially the entire time period in which the one rotary head scans over the recording medium, responsive to output pulse signals of the pulse generating circuit.
