Patent number: 6272278Abstract: A video data storage and playback scheme in which the playback of video data that has been interrupted due to the occurrence of the overtaking at the storage device can be automatically resumed at the playback device is disclosed. The storage device is controlled to transmit the read out video data to the playback device by attaching control data indicating that it is video data read out after an overtaking occurred, when the read out video data is video data stored after an occurrence of the overtaking in which a reading position of video data in a process of being read out from the storage device in response to the request from the playback device overtook a writing position of video data in a process of being written into the storage device. Then, the playback device is controlled to resume playback of video data that has been interrupted due to the occurrence of the overtaking, upon detecting the control data.Type: GrantFiled: November 30, 1998Date of Patent: August 7, 2001Assignee: Nippon Telegraph and Telephone CorporationInventors: Minoru Takahata, Kazutoshi Nishimura

Patent number: 5887110Abstract: A video data playback system for reproducing requested video data by switching coded video data to be reproduced between normal playback coded video data and fast playback coded video data according to a requested playback mode, where the normal playback coded video data are encoded by a first video coding scheme using both intra-frame coding and inter-frame coding, while the fast playback coded video data are encoded by a second video coding scheme using only intra-frame coding and having a playback bit rate and a frame rate identical to those of the normal playback coded video data. The normal playback coded video data can be obtained by encoding the original video data first, then the fast playback coded video data can be obtained by encoding selectively decoded normal playback coded video data. Alternatively, the normal and fast playback coded video data can be obtained by synchronizing start and end of encoding by the first video coding scheme and encoding by the second video coding scheme.Type: GrantFiled: March 28, 1996Date of Patent: March 23, 1999Assignee: Nippon Telegraph & Telephone Corp.Inventors: Hideki Sakamoto, Tomoaki Kawaguchi, Hideharu Suzuki, Tatsuo Mori, Hiroyuki Kimiyama, Kazutoshi Nishimura, Kouichi Itoh, Mitsuru Maruyama, Hiroshi Sugiyama, Akira Uemori, Kazuo Okada

Patent number: 5733172Abstract: A dry barrel finishing machine is disclosed. The machine includes a device to drip or spray water to wet the surface of media. The faucet of the device is located adjacent or in the barrel or barrels of the finishing machine so that it can spray water on media in the barrel or barrels. The media is cooled by the sprayed water. Since the sprayed water wets and softens the surface of the media, attrition dust on the surface of the media is easily removed during attrition. Also, since the wetted surface of the media tends to peel, it is self-sharpened. Thus the media always keeps its abrasive ability.Type: GrantFiled: May 22, 1996Date of Patent: March 31, 1998Assignee: Sintobrator, Ltd.Inventors: Kazutoshi Nishimura, Masatomo Watanabe, Takao Ishida, Satoshi Niwa, Mikitoshi Hiraga

Patent number: 5689298Abstract: A multiple readout of digital video data, capable of realizing the fast forward and fast reverse modes even under the logically multiplexed circumstances, and reducing a time required for the playback mode switching. A cycle for a readout operation is formed by a plurality of slots, each slot representing a unit time for reading a unit amount of the digital video data for each channel assigned to each user terminal; at least one of the plurality of slots forming each cycle is allocated to each channel and at least one of the plurality of slots not yet used for any channel in each cycle is additionally allocated to a user terminal which is requesting a playback mode switching; and the readout operation to read the digital video data for each channel from the storage device is carried out at every slot allocated to each channel in each cycle, by cyclically repeating the cycle for the readout operation. The requested playback mode switching can be a switching to a fast forward/reverse mode.Type: GrantFiled: November 24, 1993Date of Patent: November 18, 1997Assignee: Nippon Telegraph & Telephone CorporationInventors: Kazutoshi Nishimura, Yutaka Ishibashi, Tatsuo Mori

Patent number: 5672094Abstract: A centrifugal dry barrel finishing machine is disclosed. The machine include a plurality of barrel pots which are rotated about their axes of rotation and revolved about an axis of revolution. A mass is put in the barrel pots to finish workpieces by dry media that flows in the barrel pots. Each barrel pot has an air-intake part and an air and dust exhaust part that prevent the workpieces and dry media of the mass from passing through the parts, and the air and dust exhaust part is connected to and in communication with a dust collector through a connector device such that each barrel pot is rotatable and revolvable relative to said dust collector.Type: GrantFiled: May 22, 1996Date of Patent: September 30, 1997Assignee: Sintobrator, Ltd.Inventors: Kazutoshi Nishimura, Masatomo Watanabe, Mikitoshi Hiraga

Patent number: 5640194Abstract: A method of multiplexed data reading and visual search, in which each video program is divided into a plurality of video data groups which are stored in a prescribed order among the memory devices, and m memory control units are connected with mxn input/output channels selectively and sequentially in units of time-slots such that each memory control unit is connected with each of input/output channel at least once within a prescribed period. Then, the reading operations of the video data groups stored in the memory devices are carried out by making accesses from m memory control units in parallel at each time-slot.Type: GrantFiled: December 16, 1994Date of Patent: June 17, 1997Assignee: Nippon Telegraph and Telephone CorporationInventors: Hideharu Suzuki, Kazutoshi Nishimura, Hideki Sakamoto, Tatsuo Mori

Patent number: 5476415Abstract: An improved dry barrel finishing machine is described, in which a mass consisting of media and workpieces is flowed in the barrel of the machine for abrasive finishing of the workpieces and in which air suction is used to remove dust resulting from the finishing operation and to cool the barrel and the mass. The mass is flowed by rotation of the barrel by a motor or through the vibration of the barrel by a driving mechanism. Air inlets and outlets are provided in the barrel. An air suction device draws air through the barrel and around the workpieces and media during the finishing operation. The drawn out air picks up dust and media particles resulting from the abrasive finishing operation and cools the media and the barrel.Type: GrantFiled: October 22, 1993Date of Patent: December 19, 1995Assignee: Sintobrator, Ltd.Inventors: Kazutoshi Nishimura, Yoshinori Kohketsu, Takao Ishida
