  • Patent number: 7843315
    Abstract: Data falsification or the like is prevented and security is enhanced in an IC tag. The IC tag consists of three portions: separable portions A1 and A2, and a non-separable portion B (tag main body). The portions A1, A2, and B include IC1, IC2, and IC3, and antenna 1, antenna 2, and antenna 3, respectively, the antennas being an interface between the tag and the outside (a reader/writer device for the exchange of data with the tag). IC1 (10) and IC2 (20) are connected by a signal line L1 for signal transmission between IC1 (10) and IC2 (20). IC2 (20) and IC3 (30) are connected by a signal line L2 for signal transmission between IC2 (20) and IC3 (30). Upon separation of A1 from the tag main body, the signal line L1 is also severed. Similarly, upon separation of A2 from the tag main body, the signal line L2 is severed.

  • Patent number: 7812706
    Abstract: A tag (1) can be split into a tag (A(1-a)), a tag (B(1-b)), and a tag (C(1-c)). In the tag (A), a memory portion (A31) is included. In the tag (B), a memory portion (B32) is included. In the tag (C), a memory portion (C33), an input/output interface portion (34), and a control portion (35) are provided. The input/output interface portion (34) forms an interface for exchanging data with an external reader/writer device (not shown). The control portion (35) receives a request inputted thereto from the input/output interface portion (34) and controls the function of the tag. A split line 36 is provided between the tags (A) and (B) to allow detachment between the two tags therealong. A split line 37 is provided between the tags (B) and (C) to allow detachment between the two tags therealong. The arrangement makes it difficult to falsify data in the tag and enables an easier operation.

  • Patent number: 4975775
    Abstract: A tuner for use in two systems utilizes a determining circuit to determine whether or not a baseband signal, after demodulation includes a sound carrier. If a sound carrier is present, the determining circuit determines that the received television signal is a television signal in the NTSC system, if the carrier signal is not present, a television signal in the MUSE system. When the received television signal is a television signal in the NTSC system, switches are activated such that the baseband signal is applied to a signal processing circuit for video and a signal processing circuit compatible with the NTSC system. An averaging AFC is selected by these switches. On the other hand, when the received television is a television signal in the MUSE system, switches are activated such that the baseband signal is applied to a MUSE decoder and a keyed AFC is selected.

  • Patent number: 4399355
    Abstract: A display apparatus for tape running positions is provided with a first pulse generator (36) for generating m first pulses for each revolution of a supply reel (12) in a tape transport, a second pulse generator (38) for generating n second pulses for each revolution of a take-up reel (14), and a counter (44 to 48) for counting the number of the first pulses during one period of the second pulse. The ratio of count value change in the counter for a time period from the start to the end of the tape running is expanded to the square of the change ratio of rotational speed of the reel from the beginning to the end of the tape winding. A counting range of the counter at this time is proportional to m/n.

  • Patent number: 4372504
    Abstract: This invention is for a tape cassette having window for insertion of a magnetic head and a pinch roller formed extending from a peripheral wall of the housing of the tape cassette to one of the holding plates which holds a pair of reel hubs in place. The device according to this invention has a shutter member, and a resilient metal wire housed in the housing. The shutter member has projections which are to be engaged with an engaging member provided on a tape cassette holder member of the magnetic tape transport apparatus. The metal wire urges the shutter member to close a portion of the window formed in the holding plate. When the cassette is loaded into the loading member, the projections engage with the engaging member and the shutter member releases the closing state of the holding plate forming portion of the window against an urging force of the wire.

  • Patent number: 4363042
    Abstract: In a magnetic tape-automatic tracking method, at least one of the positions of the upper and lower edges of a magnetic tape is detected by an assembly of a tape edge position sensor and light-emitting diode. Any displacement of the running magnetic tape from its standard vertical position is determined from detected data. A generally vertical tape edge position-compensating post which applies a tensile force to the magnetic tape in contact therewith is rotated in a vertical plane by a reversible motor in accordance with the detected extent of the displacement of the running magnetic tape from its standard vertical position. The magnitude of a tensile force applied by the tape edge position-compensating post to the magnetic tape is varied, by the extent of the rotation of the reversible motor. As a result, the magnetic tape is vertically moved in the desired direction to regain its standard vertical position.

  • Patent number: 4355750
    Abstract: First and second capstans are rotated at respective speeds by first and second motors. The speeds of revolution of the first and second motors are detected as detection signals, and the revolution speed of at least one of the first and second motors is controlled in accordance with a difference between the detection signals. An offset voltage is added to one of the detection signals corresponding to the revolution speeds of the first and second motors for the control of tape tension.

  • Patent number: 4330802
    Abstract: A magnetic cassette tape record and play apparatus wherein the magnetic head thereof is fixed, comprises a push member cooperating with an operation button and which is so disposed as to abut against a pad spring received in a tape cassette. When the tape cassette is loaded or ejected in the stop mode, the push member is pressed against the pad spring to deform it against its urging force, thereby locking the cassette tape in a position untouched by the magnetic head. When the operation button is depressed for the recording or reproduction mode, then the push member is removed from the pad spring, thereby causing the pressure pad to be pressed against the magnetic head with the cassette tape disposed between the pressure pad and the magnetic head.

  • Patent number: 4320879
    Abstract: A device for stably running a magnetic recording tape of a tape cassette comprises a reel shaft and a motor connected to the reel shaft. The reel shaft and the motor make a running of the magnetic recording tape providing back tension exerted on the magnetic recording tape. Within the housing of the tape cassette, a first lever having one end rotatably fixed to the housing is mounted. A guide roller for guiding the running direction of the tape is rotatably fixed to another end of the first lever. Therefore, the first lever may swing in response to a back tension exerted on the tape. An amount of the swing of the first lever is detected by a second lever which is rotably located out of the housing and selectably engaged with the first lever. The second lever is connected to the detection means which generates an electric signal in accordance with the amount of rotation of the second lever. The electric signal is sent to the electric controlling circuit means electrically connected to the motor.
