  • Patent number: 11211882
    Abstract: A thyristor starter accelerates a synchronous machine from a stop state to a predetermined rotation speed by sequentially performing a first mode of performing commutation of an inverter by intermittently setting DC output current of a converter to zero and a second mode of performing commutation of the inverter by induced voltage of the synchronous machine. In the thyristor starter, during a first time period from start of performance of the second mode to arrival of the induced voltage of the synchronous machine at a first voltage value, a phase control angle of the inverter is changed such that a value thereof becomes larger as a rotation speed of the synchronous machine becomes higher.

  • Patent number: 11185745
    Abstract: A ball striking device, such as a golf club head, has a head that includes a face configured for striking a ball and a body connected to the face, the body being adapted for connection of a shaft proximate a heel thereof. The face has a thickened portion including an annular tapered area that tapers in thickness between an upper boundary and a lower boundary and encloses an elevated area bounded by the upper boundary. The upper and/or lower boundary defines a shape having two lobes, each with an outer edge with a convex profile, and a connecting portion extending between the lobes, such that the connecting portion is defined by two outer edges extending between the outer edges of the lobes, wherein at least one of the outer edges of the connecting portion has a concave outer profile.

  • Publication number: 20210213333
    Abstract: A golf club head which may include an iron-type golf club head body, a face plate, and a filler positioned behind the ball striking face. According to aspects of the disclosure, the face plate may include score lines which define holes in the face plate.

  • Publication number: 20200298074
    Abstract: Golf clubs and golf club heads having a weight member that is configurable in multiple positions to alter the performance characteristics of the golf club head are presented. In some examples, the weight member may be arranged in a sole of the golf club head and may include ends having different weighting characteristics. For instance, one end may be heavier or denser than another end of the weight member. The difference in weight characteristics may be due to different materials used to form the different ends, different construction of the ends, and the like. The position of the weight member may be adjusted to alter the performance characteristics of the golf club head. For instance, the weight member may be removed and rotated to position a heavier end where a lighter end was previously positioned.
