摘要： PROBLEM TO BE SOLVED: To restrain curving of a shaft body when a male screw with an odd number of threads is formed at a chamfering part and a thread part to less than an allowable upper limit.
SOLUTION: A raw material W of a planetary shaft body comprises a body screw part 41A, on which a male screw with an odd number of threads are to be formed, and a chamfering part 41B. The chamfering part 41B is inclined relative to the axis of the raw material W by an inclination angle α. The raw material W is arranged between a pair of screw dies 52. When both of the screw dies 52 are relatively moved in a direction orthogonal to the axis, a male screw with an odd number of threads is formed on the body screw part 41A and the chamfering part 41B by processing teeth 52b formed on opposed faces 52a of the screw dies 52. Also, the inclination angle α of the chamfering part 41B is set to a value in an area near "0" within a range of not more than 45° of the inclination angle α, and to a value not more than a value corresponding to an inflection point of a curve size change of the planetary shaft body after molding the male screw relative to the change of the inclination angle α.

摘要： PROBLEM TO BE SOLVED: To enhance the possibility of the recovery, from a trouble, of a valve gear of an internal combustion engine having a variable valve gear mechanism capable of continuously varying a valve lift amount and an actuator driving the variable valve gear mechanism. SOLUTION: When it is determined that a valve lift variable operation is defective in the treatment for detecting a defective valve lift amount variable operation, trouble recovering operations (S206 to S216) in which forward driving and stop of driving are repeatedly performed are performed by the actuator. By this, foreign matters caught in the variable valve gear mechanism and the actuator can be released, and the valve lift amount variable operation can be recovered from the trouble. The recovery operation can be performed immediately if the trouble occurs without waiting that specific engine operating conditions are satisfied. Since the recovery from the trouble can be performed quickly without stopping the engine, the possibility of recovery from the trouble can be enhanced. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To correspond change of a valve characteristic to an operation of an accelerator pedal or the like by adopting a mechanism for inhibiting an influence by the driving state of an internal combustion engine and an environment without using an electric motor. SOLUTION: Since the accelerator pedal 46 and a control shaft 130 are connected by a wire 48 and a winding pulley 140, the operation force of the accelerator pedal 46 directly rotates the winding pulley 40 to be transmitted to the control shaft 130. Since the operation force of a driver is imparted to the control shaft 130 as a motive power even at the time of low rotation of the engine 2 and low temperature, the change of the valve characteristic can correspond to the operation of the accelerator pedal 46 by inhibiting the influence by the driving state of the engine 2 and the environment. Thus, adjustment of the intake amount of air becomes easy and the engine driving property such as a starting property or the like becomes good. COPYRIGHT: (C)2004,JPO
