  • Patent number: 12222032
    Abstract: A control device for a vehicle, the vehicle including a belt continuously variable transmission including a mechanical oil pump driven by an engine and an electric oil pump driven by an electric motor, the engine being configured to drive a drive wheel, in which when a rotation speed of the engine is less than or equal to a prescribed rotation speed as the vehicle decelerates, driving of the electric motor is controlled to supply a hydraulic pressure from the electric oil pump to the belt continuously variable transmission, and when the deceleration of the vehicle exceeds a prescribed deceleration, the driving of the electric motor is restricted not to supply the hydraulic pressure from the electric oil pump to the belt continuously variable transmission.

  • Patent number: 6398674
    Abstract: A gut-clamping mechanism for use in stringing tennis, badminton, squash, and racquetball rackets. The apparatus includes a support post erected on a clamp block, a pair of holders wherein one holder is secured onto the top edge of said support post and the other holder is provided on the first holder in a detachable manner and such that an expanding coil spring is inserted between them. A pressing plate that has a shaft that goes through the pair of holders when the holders are joined together and with a fastening, adjusting nut hinged on the screw unit that is etched and provided at the tip of said shaft. A clamp handle is axially attached to an edge of the pressing plate, wherein a freely rotating roller is axially attached to the part that comes into contact with the side of the holder secured onto the support post in the clamp handle.

  • Patent number: 4620705
    Abstract: A gut stringing device for stringing a tennis racket or the like which permits accurate adjustment of a tension applied to the string. The device has a threaded screw and a nut mounted on it. Slide plates carrying a string clamp are moved by driving the threaded screw. Simultaneously a lever coupled to the nut swings against the bias of a spring until it touches a limit switch set at a desired pound value. The limit switch stops a motor driving the threaded screw.
