  • Patent number: 10773130
    Abstract: In a multi-piece solid golf ball having a core, a cover and an intermediate layer therebetween, the core, an intermediate layer-encased sphere and the ball have surface hardnesses which satisfy a specific relationship, and the intermediate layer and the cover have thicknesses which satisfy a specific relationship. Also, the core has a hardness profile in which the hardnesses at the core surface, core center, a position 5 mm from the core center, and a position midway between the surface and center of the core satisfy specific relationships. This golf ball, when used by mid- and high-level amateurs, enables the golfer to maintain an adequate distance on shots with a driver and achieve a good distance on iron shots, has a good spin performance on approach shots and has a good feel on impact. In addition, the ball has an excellent scuff resistance when struck with a grooved wedge.

  • Patent number: 10773131
    Abstract: A multi-piece solid golf ball having a two-layer core with an inner core layer and an outer core layer and having a cover of at least two layers including an intermediate layer and an outer layer with numerous dimples on the surface is characterized in that the hardest cover layer has a specific material hardness and the ball has a specific value obtained by subtracting the surface hardness of the overall core from the surface hardness of the hardest cover layer, a specific deflection, and a specific value obtained by subtracting the initial velocity of the inner core layer from the initial velocity of the sphere consisting of the inner core layer encased by the outer core layer. This golf ball enables relatively low head speed golfers to achieve a good distance on full shots with drivers and iron clubs and also provides a soft, comfortable feel at impact.

  • Publication number: 20200263743
    Abstract: A control system for a vehicle configured to accurately learn an initial engagement position of a clutch. The control system is applied to a vehicle comprising a clutch that selectively transmits power between a prime mover and drive wheels, and a detector that detects an input speed of the clutch rotated by the prime mover. A controller executes a learning of the initial engagement position of the clutch, if a reaction time until an input speed of the clutch is changed by engaging the clutch gradually while maintaining the input speed of the clutch to a constant speed is shorter than a threshold period of time.

  • Publication number: 20200207330
    Abstract: A control system for a hybrid vehicle configured to limit a thermal damage to a starting clutch without generating a shock. The control system is applied to a vehicle in which a prime mover includes an engine, a first motor, and a second motor. In the vehicle, the first motor is connected to the engine, and a first clutch and a second clutch are disposed between the engine and drive wheels. A controller executes a transient slip control to cause the second clutch to slip while bringing the slipping first clutch into complete engagement if a temperature of the first clutch is high. If an engine speed is changed during execution of the transient slip control, the first motor generates a collection torque to suppress the change in the engine speed.

  • Publication number: 20200207327
    Abstract: A control system for a hybrid vehicle configured to smoothly engage an engagement device while reducing a collision noise of the engagement device. The control system is configured to apply torque to a set of teeth on one half of the engagement device to shift a phase of the set of teeth in the event of teeth interference. After the completion of engagement of the engagement device, the control system further applies torque to the set of teeth on one half of the engagement device to reduce backlash between the set of teeth on one half of the engagement device and a set of teeth on the other half of the engagement device.

  • Patent number: 10658572
    Abstract: A magnetoresistance effect element includes first and second magnetic layers having a perpendicular magnetization direction, and a first non-magnetic layer disposed adjacent to the first magnetic layer and on a side opposite to a side on which the second magnetic layer is disposed. An interfacial perpendicular magnetic anisotropy exists at an interface between the first magnetic layer and the first non-magnetic layer, and the anisotropy causes the first magnetic layer to have a magnetization direction perpendicular to the surface of the layers. An atomic fraction of all magnetic elements to all magnetic and non-magnetic elements included in the second magnetic layer is smaller than that of the first magnetic layer.
