  • Patent number: 10688354
    Abstract: Provided is a method for manufacturing an iron golf club head by forging a single round rod member with a pair of dies to form, as a single piece, a body and a neck into which a shaft is to be inserted. The method includes: a first step of heating the single round rod member into a heated material; a second step of placing the heated material in the pair of dies; and a third step of forging the heated material placed in the pair of dies. In the third step, the heated material is prevented from flowing out from parting surfaces of the respective dies at a sole side of the body in the pair of dies, and the heated material blocked at the sole side in the pair of dies flows toward each of a toe of the body and the neck in the pair of dies.

  • Patent number: 10679826
    Abstract: A microwave control method is used in a microwave plasma processing apparatus including a microwave generation unit, a waveguide for guiding a microwave generated by the microwave generation unit, a tuner for controlling a position of a movable short-circuiting plate, and a stub provided between the tuner and an antenna in the waveguide and insertable into an inner space of the waveguide. The method includes detecting the position of the movable short-circuiting plate controlled by the tuner for the microwave outputted by the microwave generation unit, determining whether or not a difference between a reference position and the detected position of the movable short-circuiting plate is within a tolerable range, and controlling an insertion length of the stub into the inner space of the waveguide when it is determined that the difference between the position of the movable short-circuiting plate and the reference position is not within the tolerable range.

  • Patent number: 10569640
    Abstract: A vehicle control apparatus includes a shift control portion is configured, when determining that a shift-down action to establish one of gear positions in a transmission mechanism by release of an engagement device and engagement of a one-way clutch, is to be executed during decelerating run of the vehicle, to initiate execution of the shift-down action to establish the one of the of gear positions after an input torque inputted to the transmission mechanism becomes not lower than a predetermined negative value. The predetermined negative value is a predetermined minimum value that becomes not lower than a certain value at a point of time at which the release of the engagement device is completed in process of the shift-down action. The certain value is a value of the input torque enabling the one-way clutch to be automatically engaged.
