Patent number: 5879244Abstract: A golf ball made by adding bismuth, bismuth alloy or a mixture of bismuth alloy in bismuth to the resin compositions in amounts of 0.5-60 parts by weight per 100 parts by weight of the base resin of the said golf ball, which the carry extends farther than the other common golf balls without raising a hardness. It is because, as molding the said golf ball with the resin compositions which is added bismuth or bismuth alloy, cooling the moldings at a normal temperature after molding, bismuth or bismuth alloy gets solidified and expanded its volume by 3-3.5% and the organic polymeric materials grow dense as much as bismuth expands, that hold a lot of energy. Additionally, since this can be applied to all the core and the cover or selectively to each part, it is possible to make the golf balls with various properties that may give a satisfaction to all sorts of golfers. Furthermore, the golf balls according to the present invention is soft to the touch, which has a good hit feeling.Type: GrantFiled: April 8, 1997Date of Patent: March 9, 1999Assignee: Ilya Co.

Patent number: 5238986Abstract: The composition of the present invention is composed of finely divided solid refractory material suspended in a nonaqueous liquid slip composition. The nonaqueous liquid slip composition consists essentially of a deflocculent composed of a vinyl chloride and vinyl acetate resin dissolved in an organic solvent. The composition may be slip cast or cold formed into a low density article which is then sintered into a dense product.Type: GrantFiled: February 21, 1992Date of Patent: August 24, 1993Assignee: Praxair S.T. Technology, Inc.Inventor: Lionel C. Montgomery

Patent number: 5205971Abstract: Non-whiteware ceramic articles having an increased green strength are prepared from slip compositions containing a polyalkylene polyamine as an additive or a mixture of a polyalkylene polyamine and binder as an additive. An example of such an additive is tetraethylenepentamine or a mixture of tetraethylenepentamine and a styrene butadiene latex.Type: GrantFiled: October 2, 1990Date of Patent: April 27, 1993Assignee: The Dow Chemical CompanyInventors: Alan P. Croft, Brian D. Koblinski

Patent number: 5126075Abstract: Material for a housing of electronic components, a compound of synthetic resin, which contains ferrite powder and carbon fiber, is bestowed with original properties of the synthetic resin, such as lightness and freedom of molding, high permeability brought by ferrite powder, and high conductivity and mechanical properties by a designated carbon fiber. The material is made into a light housing with various shapes by injection molding or vacuum molding. The housing concentrates on its surface magnetic flux from external low-frequency field and shields the electronic components from electromagnetic wave noise and low-frequency magnetic field, preventing electromagnetic troubles of the electronic components.Type: GrantFiled: October 27, 1989Date of Patent: June 30, 1992Assignee: Kitogawa Industries Co., Ltd.Inventor: Asaharu Nakagawa

Patent number: 5112529Abstract: The present invention relates to a conductive material and a process for producing said conductive material. More particularly, the present invention relates to a conductive material comprising (a) a substrate obtained from a polycarbodiimide resin and (b) a dopant, which is superior in oxidation resistance, mechanical strengths and flexibility, and useful as a material for electronic field, as well as to a process for producing said conductive material.Type: GrantFiled: September 4, 1990Date of Patent: May 12, 1992Assignee: Nisshinbo Industries, Inc.Inventor: Kazuo Saito

Patent number: 5104602Abstract: Fibers formed of a blend of metal oxide, such as titanium or zirconium oxide, with etheric phosphazene are formed by preparing solutions of etheric phosphazene and inorganic alkoxides, such as titanium isopropoxide. The solutions are then formed into fibers and cured at room temperature or with moderate heating. Fibers produced can be extensible, tough, hard, flexible, or brittle. They are multicomponent blends of the titaninum or zirconium oxide and phosphazene. The composite may be doped with low lattice energy salts to form conductive fibers.Type: GrantFiled: December 15, 1989Date of Patent: April 14, 1992Assignee: Eastman Kodak CompanyInventors: Christine J. T. Landry, Wayne T. Ferrar, Bradley K. Coltrain

Patent number: 5098609Abstract: A paste including a thermally conducting solid filler, a nonaqueous liquid carrier and a stabilizing dispersant. The pastes are highly concentrated, of low viscosity, electrically resistive, highly thermally conducting and stable. The pastes are easily applicable to electrical and electronic devices and may be removed therefrom with common solvents to access components where necessary.Type: GrantFiled: November 3, 1989Date of Patent: March 24, 1992Assignee: The Research Foundation of State Univ. of N.Y.Inventors: Sushumna Iruvanti, Rakesh K. Gupta, Eli Ruckenstein
