  • Patent number: 9654812
    Abstract: An encoding apparatus adds delay time information DTI indicating initial delay time i_d and delay time d of each group data to a position to be read prior to frame data by a decoding apparatus in the group data of encoding stream data DBI and transmits the same to the decoding apparatus 3. Namely, the encoding apparatus does not transmit initial offset delay time i_of to the decoding apparatus 3. The encoding apparatus starts to read and transmit the encoding stream data DBI from a transmission buffer at a predetermined bit rate R at timing designated by the initial offset delay time i_of.

  • Patent number: 5243811
    Abstract: 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.

  • Patent number: 4536195
    Abstract: 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.
