Patent number: 5243811Abstract: A peripheral surface of an annular shaped grinder is distributed with grinding particles. The grinding particles have a particles distribution such that the spacing between the grinding particles in the axial direction is less than 2/3 of the mean diameter of the particle and that the spacing between grinding particles in the circumferential direction is about 5-80 times of the mean particle diameter. The grinder is manufactured by a method of forming a pattern of an adhesive layer on a synthetic resin sheet, fixing the grinding particles to the patterns and laminating the sheets with fixed particles.Type: GrantFiled: December 23, 1991Date of Patent: September 14, 1993Assignee: Kabushiki Kaisha Komatsu SeisakushoInventors: Hiroyuki Kitabayashi, Tadayuki Ishikawa

Patent number: 4536195Abstract: Grinding stones, especially resinous and metallic grinding stones which have a controlled distribution of abrasive grains are made by a novel method, in which electrically conductive layers of such pattern which controls sites to be bonded with the grains are formed on the selected surface of a binder sheet, the sheet is immersed in an electrolytic bath containing metallic ions and the grains, the grains are fixedly mounted on the aforementioned sites by metals deposited on the surface of binder sheet with electric paths between the conductive layers and an opposite electrode in the bath, and a plurality of said sheets are placed in layers and warm or hot pressure-molded. When the binder sheet is made from electrically conductive materials, the pattern of the conductive layers is made by masking.Type: GrantFiled: October 1, 1984Date of Patent: August 20, 1985Assignees: Kabushiki Kaisha Komatsu Seisakusho, Noritake Co., Ltd., Noritake Diamond Industries Co., Ltd.Inventor: Tadayuki Ishikawa
