    摘要： An iron golf club and a set of iron golf clubs that have a variable weight distribution. Each iron golf club head has a cavity and a raised wall portion that extends upward from the sole and offset from the cavity. The raised wall portion is separated from the cavity by a groove set at an oblique angle to the face portion of the iron golf club The groove deepens the center of mass depth and lengthens the effective face length of the iron golf club. The width of the groove may vary between each golf club in a set of iron golf clubs, such that the width of the groove of the long irons is greater that the width of the groove of the middle irons, and the width of the groove of the middle irons is greater than the width of the groove of the short irons.

    摘要： A form-fitting chest protector. In one embodiment, the chest protector includes a pair of detachably secured wing portions. A main portion of the chest protector has a variable thickness and substantially overlies the chest and abdomen of the athlete to absorb impacts to the athlete from a projectile. The wing portions are separate from the main portion, but are detachably secured to the chest protector to permit each wing portion to be adjustable when the chest protector is worn by the athlete. The wing portions facilitate a constant form-fit no matter how the body of the athlete flexes.

    摘要： The invention is a lamp quality judgement apparatus and judgement method which judge quality by detecting the state of gas sealed in an electric lamp such as a gas-filled incandescent lamp, etc. in which gas with an Argon-Nitrogen mixture as its main component is sealed. More particularly, a lamp in which such gas is sealed is classified as a good product or as a bad product by imposing a high DC voltage or a high AC or pulsed voltage with a comparatively low frequency of 1 kHz or less across the lamp's valve and filament coil to produce discharge and emission, in the lamp, of a light in a wavelength region in the vicinity of 560 nm and judging the radiation state in this 560 nm light spectrum, i.e., the state of discharge in the lamp. The means employed for detecting the light spectrum radiation state include means for judging lamp quality by monitoring the temporal response characteristic in the light spectrum in the 560 nm wavelength region and means for effecting accurate judgement of lamps regardless of variations in the state of discharge in lamps by detecting the difference in intensity of the light spectra of two wavelength regions which are the light spectrum of a 560 nm wavelength region and a light spectrum of a wavelength region other than the 560 nm wavelength region.

    摘要： A front wheel steering control device improves the handling and stability of a vehicle with respect to the steering wheel angles. The front wheel steering control device includes an input device for obtaining the steering wheel angle and the vehicle velocity, a first computing device for computing a yaw-rate for the vehicle which maintains the vehicle gravity center point sideslip angle at zero based on the steering wheel angle and the vehicle velocity that are obtained by the input device, a second computing device for computing a target front wheel actual steering angle for realizing the yaw-rate calculated by the first computing device, a control device for performing a steering control of the vehicle based on the target front wheel actual steering angle calculated by the second computing device. The ideal determination of the vehicle steering gear ratio and the derivative steering gain are relatively easy.
