Publication number: 20160332036Abstract: A golf ball with a deposited layer is disclosed. The deposited layer is not produced by a molding process, such as injection molding or compression molding. Instead, the deposition process is produced by another process, such as thermal spraying or sintering. The deposited layer may include partially fused particulate material. The deposited layer may be added to a golf ball design as one or more supplemental layers. The deposited layer may also be provided in a golf ball design as a substitute for one or more layers. A golf ball may further include a combination of one or more supplemental deposited layers and one or more substituted deposited layers.Type: ApplicationFiled: July 14, 2016Publication date: November 17, 2016Applicant: NIKE, Inc.Inventors: Arthur Molinari, Michael Wallans, Takahisa Ono, Seisuke Tomita

Publication number: 20150144258Abstract: A golf ball is provided capable of having various characteristics based on having an aggregated layer core. The golf ball includes an inner core, an outer shell enclosing the inner core, and an intermediate core enclosing the inner core. The intermediate core includes sublayers thermoplastically fused together to form an aggregated intermediate core layer having overall characteristics formed as a combination of the sublayer characteristics. A method of forming a golf ball core having an aggregated layer core can include forming a first and second stack of nested cups, thermoplastically bonding each of the stacks to each other to form first and second aggregated cups, arranging the aggregated cups around a golf ball inner core, and bonding the aggregated cups to each other. In some configurations, the sublayers can include ultrathin sublayers less than 20 microns thick, and in some configurations, the sublayers can include injection molded sublayers.Type: ApplicationFiled: November 21, 2014Publication date: May 28, 2015Applicant: NIKE, Inc.Inventors: Yutaka KABESHITA, Kerby LaVar Maxwell, Arthur Parker Molinari, Bradley C.

Patent number: 5651741Abstract: A golf ball is provided with a marking portion including a hologram implementing a color and/or pattern produced by optical interference. The marking portion is provided on the entire surface of the golf ball or only in dimples. The marking portion including a hologram reflects light and thereby glitters, and is visually recognized as a three-dimensional image, thereby improving visibility of the ball from a distance. The marking portion including a hologram allows an image to be readily reproduced by irradiating a laser beam thereto. Thus reproduced image facilitates an automated inspection for the appearance of the marking portion.Type: GrantFiled: May 9, 1996Date of Patent: July 29, 1997Assignee: Bridgestone Sports Co., Ltd.Inventors: Yutaka Masutani, Keisuke Ihara, Seisuke Tomita

Patent number: 5439227Abstract: A multi-piece solid golf ball has a solid core of multi-layer configuration including an inner layer circumscribed by an outer layer. The core inner layer is formed from a rubber composition. The core outer layer is formed thereon by injection molding a mixture of 100-50 wt % of a polyether ester type thermoplastic elastomer having a Shore D hardness of 30-50 and a Tg of up to -25.degree. C. and 0-50 wt % of an ethylene-(meth)acrylate copolymer ionomer having a flexural modulus of 200-400 MPa. The core is surrounded by a cover of an ethylene-(meth)acrylate copolymer ionomer having a flexural modulus of 200-450 MPa and a Shore D hardness of 55-68. The ball shows improved flying performance, feel on impact and durability and lends itself to mass production.Type: GrantFiled: August 25, 1993Date of Patent: August 8, 1995Assignee: Bridgestone Sports Co., Ltd.Inventors: Yoshinori Egashira, Seisuke Tomita
