    摘要: A groove is provided a surface on a cavity portion side of a sole portion in a head portion of an iron golf club, and a thickness of a ball hitting portion in a face portion is made larger than a thickness of a top edge side portion of the face portion and at least as large as a thickness of a sole side portion of the face portion. In a golf club set according to the present invention, the groove has the greatest depth in a long iron golf club, while the groove has the smallest depth in a short iron golf club or no groove is provided in the short iron golf club.

    摘要: An engine combustion condition judging method for detecting a crank angle speed of a multiple cylinder engine, for judging a combustion condition of each of cylinders of the engine based on the detection of the crank angle speed, wherein the improvement includes the steps of setting a predetermined crank angle range selectively determined within a range between a crank angle at which a combustion substantially terminate in a given cylinder and another crank angle at which a combustion substantially start in the next cylinder for detecting a crank angle speed property, and judging the combustion condition based on said crank angle speed property within the predetermined crank angle range. The combustion condition can be obtained reliably so that an appropriate A/F control can be accomplished irrespective of the engine operating condition.

    摘要: The method for forming a chemical conversion film on a substrate made of aluminum or its alloy which comprises the steps of: (a) etching a surface of the substrate with an aqueous solution of acid or alkali; (b) immersing the etched substrate in an aqueous, phosphate-based chemical conversion solution which is substantially free from fluoride ions; and (c) applying a negative voltage to the substrate during at least a part of the immersion step so that a potential of the substrate reaches a predetermined minimum potential which is lower than a natural electrode potential of the substrate in the aqueous chemical conversion solution.
