  • Patent number: 9568026
    Abstract: In an electric motor-driven booster, a sharp change of reaction force to an operation of a brake pedal is reduced to improve the brake pedal operation feeling. Operation of the brake pedal causes an input rod (34) and an input piston (32) to advance, and an electric motor (40) is driven according to the movement of the input piston to propel a primary piston (10) through a ball-screw mechanism, thereby generating a desired brake hydraulic pressure in a master cylinder. At this time, the input piston receives the hydraulic pressure in the master cylinder to feed back a part of reaction force during braking to the brake pedal. When the brake pedal is further depressed after the output of the electric motor has reached a maximum output and the primary piston 10 has stopped, a lock nut abuts against a movable spring retainer and compresses a reaction force spring.

  • Patent number: 9562279
    Abstract: A boring cutter body (5) is inserted into a circular hole (3) and is rotated and moved in an axial direction, whereby screw-shaped groove parts (11) are formed by using a tool bit (9) provided on a tip end of an outer peripheral portion, and broken surfaces (15) are formed by breaking tips of ridge parts generated by formation of the groove parts (11). Moreover, the groove parts (11) are processed through electric discharge machining using a wire electrode (17) provided to the boring cutter body (5) behind the tool bit (9) in the rotating direction, thereby forming finely roughened portions (41) having more finely roughened shapes than the broken surfaces (15).

  • Patent number: 9562381
    Abstract: A vehicle window assembly includes a body structure, a hinge structure, and a covering panel. The covering panel overlies an inboard side of a window opening, and comprises a hanging loop with a hanging section. The hinge structure comprises a hinge base and a hinge cover, and is attached to the upper portion of the body structure. The hinge cover attaches to the hinge base to form a loop support portion between the hinge base and the hinge cover, and to enclose a hanging loop, preventing removal of the hanging loop. The loop support portion enables the hanging loop to be movable between a secured position in which the hanging section is positioned adjacent the inboard end of the hinge base, and an unsecured position in which the hanging section is disposed adjacent the outboard end of the hinge base.

  • Patent number: 9562382
    Abstract: A vehicle door hinge structure includes a first bracket, a second bracket, a hinge arm and a compressible check structure. The hinge arm has a first end that s attached to the first bracket for pivoting movement about a first pivot axis. The second bracket is attached to a second end of the hinge arm for pivoting movement about a second pivot axis. The compressible check structure is fixed in position to the first bracket. The compressible check structure is adjacent to and spaced apart from a stop surface of the first bracket. The compressible check structure extends upward away from a surface of the first bracket in an uncompressed state. However, a movement limiting surface of the hinge arm contacts and compresses the compressible check structure during a portion of movement of the hinge arm.

  • Patent number: 9562948
    Abstract: A control device of a secondary battery using, as positive electrode material, positive electrode active material showing a difference of an open circuit voltage curve between during charge and discharge, detects whether the secondary battery is in a charge state or a discharge state. When the secondary battery is in the charge state, the control device calculates, as a current SOC, a value that is lower than an SOC corresponding to a current open circuit voltage of the secondary battery on a reference SOC-open circuit voltage curve showing a relationship between the SOC and the open circuit voltage, which becomes a reference upon calculating the current SOC. When the secondary battery is in the discharge state, the control device calculates as the current SOC, a value that is higher than the SOC corresponding to the current open circuit voltage of the secondary battery on the reference SOC-open circuit voltage curve.

  • Patent number: 9562383
    Abstract: A hinge hydraulic infinite check structure includes a paddle having at least one hydraulic aperture is rigidly fixed to a shaft. The pivot shaft is supported for pivoting movement within a case. The case includes a wall portion rigidly fixed to a cylindrically shaped inner surface and extends radially inward to the shaft. Pivoting movement of the pivot shaft forces the hydraulic fluid to move through the aperture from a first side to a second side of the paddle generating movement resistance. With the pivot shaft being stationary relative to the fluid chamber, equilibrium of fluid pressure of the hydraulic fluid at the first side and the second side of the paddle imparts a resistance to pivoting movement of the pivot shaft relative to the fluid chamber.
