摘要： A clutch is provided with a drive-side rotational body and a driven-side rotational body, which can move in the axial direction between a coupled position and a decoupled position. The driven-side rotational body has a groove having a helical portion and an annular portion that is deeper than the helical portion. The driven-side rotational body is urged toward the coupled position by an urging member. The driven-side rotational body is moved to the decoupled position against the urging force of the urging member by insertion of a pin into the helical portion. A projection is provided on the tip of the pin, and a recessed groove for accommodating the projection when the pin is inserted into the helical portion is provided in the bottom surface of the helical portion.

摘要： The clutch is provided with a drive-side rotational body, a driven-side rotational body, driven-side rotational body, and an urging member. The driven-side rotational body is movable in the axial direction of the drive-side rotational body between a first position, at which the driven-side rotational body is coupled to the drive-side rotational body, and a second position, at which the driven-side rotational body is decoupled from the drive-side rotational body. The urging member urges the driven-side rotational body from the second position toward the first position. The driven-side rotational body includes a helical groove that extends in the urging direction of the urging member. The clutch is further provided with a pin that can be inserted into the helical groove.

摘要： A clutch is provided with a drive-side rotational body and a driven-side rotational body, which is movable in the axial direction of the drive-side rotational body between a coupled position. The driven-side rotational body has a groove having a helical portion and an annular portion. The clutch also includes an urging member and a pin that is selectively inserted into and retracted from the groove. The clutch moves the driven-side rotational body to the decoupled position against the urging force of the urging member by inserting the pin in the helical portion. The clutch further includes a restricting portion that restricts shifting of the position of the pin from the annular portion to the helical portion when the pin is positioned in the annular portion.

摘要： A variable valve operating apparatus for an internal combustion engine is provided which includes a helical wall part provided in a guide rail for changing valve opening characteristics of a valve and a projection part, and can secure a contact area between the two when the two are engaged, thus successfully reducing the contact pressure generated between the two. The placement of the projection part with respect to the helical wall part is determined such that the central axis line of the projection part and the central axis line of a camshaft perpendicularly intersect with each other in a state in which the projection part is protruded toward the guide rail by an actuator.

摘要： Provided is a variable valve operating apparatus for an internal combustion engine, which can switch, based on an actuation of a single actuator, operating characteristics of valves for a plurality of cylinders collectively and smoothly using a rigid member, while suppressing an increase in wear of a guide rail and reducing the number of delay mechanisms.A changeover mechanism to switch operating characteristics of valves for each cylinder of first and second cylinder groups is provided. The changeover mechanism includes link shafts as a rigid member which is displaced when being engaged with a helical guide rail as a result of the actuation of an electromagnetic solenoid. The changeover mechanism includes a delay mechanism, which delays the displacement of the second link shaft in a cylinder in which the valves are lifting when the electromagnetic solenoid is actuated, at some point in the link shafts between the first cylinder group and the second cylinder group.

摘要： A surface treating method uses an electric discharge machining to form a coating layer having strong adhesion and excellent characteristics on a metal surface such as a hard metal. A discharge electrode is formed by powders containing metal hydride. Electric discharge is generated in a working fluid containing carbon between the discharge electrode and a workpiece. Thus, a coating layer of the metal hydride is formed on a surface of the workpiece.
