Patent number: 6045041Abstract: Cassette managing data is read or written with a cassette accommodated in its bin. Cassettes 2a, 2b, 2c, and so on are attached at particular positions thereof to IC cards 1a, 1b, 1c, and so on respectively. Cassette bins 4a, 4b, 4c, and so on have read/write devices 3a, 3b, 3c and so on respectively at positions communicable with the IC cards. Control information of each cassette is read with the cassette accommodated in its bin from the read/write device and the read control information is controlled by a control server 5 via a LAN 9a. A robotics unit 8 is controlled by the control server 5 via a LAN 9c to move cassettes to the bins 4a, 4b, 4c, and so on or an image and/or sound information input/output block 7.Type: GrantFiled: December 12, 1997Date of Patent: April 4, 2000Assignee: Sony CorporationInventors: Shosuke Tanaka, Mitsutaka Enomoto, Teruyuki Yoshida

Patent number: 5297131Abstract: An area for recording a preformated encoding pattern is provided on a rewritable disk in order to obtain information of an eccentricity produced when the disk is chucked. The information of the eccentricity produced at the time of disk chucking is detected, while the disk is being driven, from a reference pulse obtained by reproduction of the encoding pattern and, on the basis of the eccentricity information, the frequency of the clock for writing data or reading data is modulated according to eccentric positions.Type: GrantFiled: May 28, 1992Date of Patent: March 22, 1994Assignee: Sony CorporationInventor: Shosuke Tanaka

Patent number: 5091636Abstract: An apparatus for detecting modulated informations from emitted light turned around by an object is disclosed, in which a non-modulation interval is provided in a light signal from a transmitting side, an information from the transmitting side is received at a receiving side by its light receiving elements and the light signal from the transmitting side during the non-modulation interval is modulated and then reflected back to the transmitting side thereby transmitting a signal. Consequently, the space and the cost of the receiving side can be reduced, and the optical axes of the transmitting side and the receiving side can be positively adjusted with ease. Also, according to the present invention, a bar code is disclosed, which includes an optical recursive reflection member which reflects back a light incident thereon in substantially the same direction of the incident light. This bar code further includes a shutter which can modulate a code.Type: GrantFiled: July 3, 1991Date of Patent: February 25, 1992Assignee: Sony CorporationInventors: Hirohisa Takada, Shosuke Tanaka

Patent number: 4363048Abstract: A counting clock generator for a video tape recorder, in which two different phase counter clock signals at a pulse repetition frequency corresponding to the running speed of a tape are processed to obtain a direction detection signal indicating the direction of running of the tape and a clock signal at a frequency of predetermined times that of the two different phase counter clock signals, and the clock signal thus obtained is counted by a reversible counter, which is controlled for switching between up-counting and down-counting by the direction detecting signal with data "0" preset when the tape is running forward and data "maximum value" preset when the tape is running backward, for producing two revised counter clock signals of different phases according to the count output signal from the reversible counter.Type: GrantFiled: November 19, 1980Date of Patent: December 7, 1982Assignee: Sony CorporationInventors: Shosuke Tanaka, Fumiyoshi Abe

Patent number: 4343022Abstract: Apparatus is disclosed for use in a video signal reproducing system of the type having first and second rotary reproducing transducers for reproducing video and vertical synchronizing signals from record tracks on a record medium, in which the transducers exhibit a predetermined angular separation therebetween, the video signal reproducing system also having means for producing a reference synchronizing signal in phase synchronism with the vertical synchronizing signal reproduced by the first transducer. The apparatus is adapted to produce a substantially phase synchronized reference signal regardless of the particular transducer which is used to reproduce the video signals. The apparatus comprises a delay circuit for delaying the reference synchronizing signal by an amount corresponding to the predetermined angular separation between the transducers; and a switching circuit supplied with this delayed as well as the undelayed reference synchronizing signal.Type: GrantFiled: July 8, 1980Date of Patent: August 3, 1982Assignee: Sony CorporationInventors: Shosuke Tanaka, Mitsushige Tatami
