Apparatuses and methods for controlling the discharge of subword lines are described. The rate of discharge and/or the voltage level discharged to may be controlled. In some embodiments, a main word line may be driven to multiple low potentials to control a discharge of a subword line. In some embodiments, a first word driver line signal and/or a second word driver line signal may be reset to control a discharge of a subword line. In some embodiments, a combination of driving the main word line and the first word driver line signal and/or the second word driver line signal resetting may be used to control a discharge of the subword line.

In the inlet passage structure of the V-type internal combustion engine, front and rear banks have inlet ports with a nearly identical inlet passage length, and an inlet chamber is connected to a top end openings of the inlet ports. A throttle body and the inlet chamber are offset on a side leading to a cylinder on a side away from the throttle body. The inside of the inlet chamber is formed with a nearly straight inlet passage from the throttle body to the top end opening of the inlet port leading to the cylinder bore on the side away from the throttle body, and a curved inlet passage to the top end opening of the inlet port leading to the cylinder on a close side.

In a rotation angle sensor attaching structure for detecting rotation of a rotational angle detection object shaft through a reduction gear, an outer race of a bearing is force fitted in and secured to a central portion of the reduction gear, and an inner race of the bearing is secured to a supporting wall by a supporting bolt. A sensor-connecting element of a rotation angle sensor, which extends across a head portion of the supporting bolt, is secured integrally to an outer side face of the reduction gear. Such arrangement achieves a minimal size of the rotation angle sensor attaching structure.

A valve train of an internal combustion engine having a swing of a link mechanism that is stabilized to stabilize the operating characteristics of an engine valve. A camshaft is provided together with a valve operating cam pivotally supported by the camshaft so as to operatively open and close an engine valve. A link mechanism allows a drive cam rotated integrally with the camshaft to swing the valve operating cam, and a drive mechanism swings the link mechanism, wherein opening and closing of the engine valve are started in a buffer section of the valve operating cam, and opening/closing timing of the engine valve is controlled by the drive mechanism swinging the valve operating cam via the link mechanism, without the provision of a buffer transition section and a buffer constant-speed section encountered at the time of transiting from a base circle to a cam lobe of the drive cam.
