A speed measuring device has an antenna with directionality that transmits a transmission wave toward the moving body based on a transmission signal supplied from a Doppler sensor, and receives a reflected wave reflected by the moving body to generate and supply to the Doppler sensor a reception signal. An imaginary line extending along a direction in which a gain of the antenna is maximized is defined as an imaginary axis that indicates an orientation direction of the antenna. An antenna supporting unit is provided on a housing and supports the antenna so an inclination of the imaginary axis can be altered. A display is provided on an upper surface of the housing with a flat display surface of a rectangular shape facing upward and displays various display contents including the movement speed of the moving body on the display surface.

A golf club head and a golf club provided with the golf club head. The head has outer shell structure portions including a hosel portion, a face portion, a sole portion, a crown portion, and a side portion and a joining portion where a crown member used in the crown portion is bonded to a member used in another outer shell structure portion. The member to be used as the crown member has an equivalent rigidity not more than 0.8 times as high as that of a sole member used in the sole portion where the equivalent rigidity of a member used in any one of the outer shell structure portions is defined as the product of the thickness of the relevant member and the elastic modulus of the member in a direction in which a golf ball-striking surface of the face portion is oriented.
摘要:
Evaluation of the durability or the coefficient of restitution of a golf club head 1 is performed by measuring a response signal of an impact surface 10 of a golf club head 1 when imparting a vibration to the impact surface 10, finding a value of the peak frequency of the first resonance frequency or the like located within a predetermined frequency range of the measured response signal, and finding the ratio of this peak frequency value with respect to a reference value. Further, control of the quality of the restitution characteristics in a initial state, or quality of the golf club head that deteriorates over time, is conducted by utilizing the evaluation results. The golf club head 1 is provided with a label 12 for displaying the peak frequency measured immediately after manufacture as an initial value. Further, in manufacturing a golf club, the quality of the golf club head immediately after manufacture is controlled by the peak frequency.
摘要:
A method of evaluating restitution characteristics of a golf club head, a system for evaluating the restitution characteristics and a golf club, are provided in which a coefficient of restitution of a golf club head is inferred and obtained without disassembling the golf club by removing the golf club head away from a shaft and the coefficient of restitution may extremely easily be obtained for a short period of time. At first, an external force to a striking face of the golf club head is imparted to perform impact vibration. A response signal of the striking face under the impact vibration is acquired to obtain a resonant frequency of the striking face. A coefficient of restitution is calculated from the resonant frequency when the golf ball is struck by the striking face, whereby restitution characteristics of the golf club head are inferred and evaluated.
