4 results about "Increasing weight" patented technology

The goal is to suppress taxi wear and touchdown wear while ensuring high fracture pressure without significantly increasing weight. [Solution] In the first reference state, the conditions 0 ≤ δ35 / Rc ≤ 0.004 and 0.015 ≤ δ90 / Rc ≤ 0.025 are satisfied, and the belt layers 5a to 5i include two or more spiral belt layers 51 and one or more zigzag belt layers 52, and the two or more spiral belt layers 51 include a first spiral belt layer 511 whose tire width direction edge 51c is located outside the tire width direction of the shoulder circumferential groove 812, and a second spiral belt layer 512 whose tire width direction edge 51c is located between the center circumferential groove 811 and the shoulder circumferential groove 812.

Provided is a pruner that does not increase weight and cost and can reduce damage to a gear when a blade is jammed with a simple configuration. The pruner includes an electric motor (50), a blade drive gear (61) that is rotationally driven by the electric motor (50), an eccentric cam (62) provided on the gear (61), and a pair of blades that are in a relatively slidable manner. The pair of blades are reciprocated in opposite directions along their longitudinal directions by the eccentric cam (62), so that cutting edges (24) that are spaced apart from each other and are provided in a protruding manner on the pair of blades are ground against each other. An impact absorbing structure (70) is provided between a connecting structure (28) of the eccentric cam (62) and the cutting edges (24) of the blades.

The invention relates to a composite material type golf club head which comprises a club head body formed by molding a composite material and a heterogeneous composite type ball hitting component fixedly connected to the front end of the club head body. The heterogeneous combined type ball hitting component comprises a ball hitting panel formed by a metal material and a component base part integrally formed on the outer periphery of the ball hitting panel by a composite material, and the ball hitting panel is embedded into a panel embedding part of the component base part by an embedding edge protruding outwards on the periphery of a panel body of the ball hitting panel. Therefore, the composite material type golf club head has the functions of reducing the weight and increasing the balance weight margin, and a tight combination effect is generated between heterogeneous materials of the metal material hitting panel and the component base part which is integrally formed by the metal material hitting panel and the composite material in a mold, so that the stability of heterogeneous combination is improved.
