A golf club shaft (10), tubular and having a hollow portion, which includes a laminate of fiber reinforced prepregs (21 through 23, 24A, 25 through 29). The laminate has a first part (I) composed of a plurality of first prepregs (P1) and a second part (P2). A loss factor (tan δ) of the first part (I) is set to not less than 0.005 nor more than 0.02, when the loss factor is measured at a frequency of 10 Hz under a condition of 10° C. A loss factor (tan δ) of the second part (P2) is set to not less than 0.10 nor more than 0.50, when the loss factor is measured at a frequency of 10 Hz under the condition of 10° C.

Abstract:
A magnetic resonance imaging method comprising a step for applying one or more gradient magnetic field pulses continuously, a step for calculating a residual magnetic field being generated from a magnet by an gradient magnetic field pulse based on a residual magnetic field response function representing the relation between the strength of the gradient magnetic field pulse being applied and the strength of a residual magnetic field being generated, and a step for correcting the residual magnetic field thus calculated. The magnetic resonance imaging method is further provided with a step for updating the residual magnetic field response function with time depending on the application history of the gradient magnetic field pulses being applied continuously.
Abstract:
Each point obtained by plotting flexural rigidity EI measured at ten sites on a shaft is defined as from T(1) to T(10) in this order from the head side, and the formula representing a line K that passes the T(1) and the T(10) is [Y=aX+b1]. The values at the Y-intercepts on the lines that are parallel to the line K and that pass the points of from T(2) to T(9), respectively, are defined as from b2 to b9, respectively, and the minimum value among the values at the Y-intercept b2 to b9 is defined as bmin. In this shaft, slope “a” of the line K is 0.04 or greater and 0.06 or less; any one of the b3, b4, b5, b6, b7 and b8 is smaller than b1; and the bmin is any one of b4 to b7. The value (b1−bmin) is 24 (N·m2) or greater and 35 (N·m2) or less, and the value (b9−b1) is 0 or greater and 10 (N·m2) or less. This shaft achieves excellent flight distance performance and directionality of the hit ball.
Abstract:
In diffusion weighted imaging, motion monitoring navigation echoes are measured at every measurement of data after applying an RF excitation pulse, and one of them is set as a reference navigation echo. The reference navigation echo and other navigation echoes are one-dimensionally Fourier-transformed, a linear phase gradient thereof is calculated from those data, a linear phase gradient of the reference navigation echo is compared with those of other navigation echoes, and it is judged whether a difference therebetween is within an acceptable value or not. An echo signal corresponding to a navigation echo having the above difference being larger than the acceptable value is judged that correction based on the navigated motion correction is not applicable therein, and the image is produced by using an echo signal measured along with a navigation echo having the difference being the acceptable value or less. In this manner, a motion component included in the echo signal used for producing the image is made uniform and motion artifacts are eliminated.
Abstract:
A golf club grip includes: a grip body including a grip cylinder portion and a grip end portion disposed at one end of the grip cylinder portion and formed with a through-hole for communicating a grip interior with the outside; and a vibration absorption member formed from a viscoelastic material and formed separately from the grip body. The vibration absorption member is removably attached to the grip body. The vibration absorption member includes: a plane portion and a bar-like portion formed integrally with the plane portion. The bar-like portion extends through the through-hole of the grip end portion as projecting inwardly of the grip cylinder portion.
Abstract:
A method for transferring a thin plate is provided, in which three or more grasping claws of a transfer arm grasp the periphery of the thin plate in order to transfer it to a predetermined transfer position, and three or more holding claws hold the periphery of the thin plate in the transfer position. The transfer arm rotates about a shaft which is in a direction of a vector sum of a first vector perpendicular to a surface of the thin plate before transfer, and a second vector perpendicular to the surface of the thin plate after the transfer, to transfer the thin plate with changing the posture thereof.
Abstract:
Arranged on both sides of a thin plate are optical displacement gauges that irradiate measurement lights onto surfaces of the thin plate and receive the measurement lights reflected by the surface so as to measure displacements of the surfaces of the thin plate. Variation of thickness of the thin plate is obtained on the basis of the displacements of the surfaces of the thin plate measured by each of the optical displacement gauges. Each of the optical displacement gauges detects the displacement of a respective surface of the thin plate with high accuracy by irradiating the measurement light to the thin plate two times.
Abstract:
Graphite is placed in a case, and the case is set in a furnace. The interior of the furnace is subjected to sintering to produce a porous sintered member of graphite. After that, the case with the porous sintered member therein is taken out of the furnace, and is set in a recess of a press machine. Subsequently, molten metal of metal is poured into the case, and then a punch is inserted into the recess to forcibly press the molten metal in the case downwardly. Open pores of the porous sintered member are infiltrated with the molten metal of the metal by the pressing treatment with the punch.
Abstract:
A stylus having a curvature radius of 1 mm or less is attached to the extremity of a probe. When the profile of an object is measured with high precision by causing the stylus to follow a measurement surface of the object, a reference ball for calibration is first measured, thereby surface profiling the object. From the measurement data, a contact position where the stylus contacts with the object is determined. A positional error caused by a curvature radius of the stylus is corrected by using an angle of inclination of the measurement surface in that contact position. The amount of profile error in the contact position is extracted by using the profile error data pertaining to the stylus determined by measurement of the reference ball. The amount of profile error is added to the measurement data, thereby correcting the profile error caused by the curvature radius of the stylus.
