  • Patent number: 5395067
    Abstract: A tape travel controlling system in a recording/reproducing apparatus according to the present invention includes a tape width detector, a tape traveling path adjuster for changing a set condition(s) for a tape guide(s), and a tape traveling path controller, and is constructed so that the tape traveling path controller controls the amount of change in the set condition(s) for the tape guide(s) in the tape traveling path adjuster in accordance with an output signal provided from the tape width detector.
    Type: Grant
    Filed: April 25, 1994
    Date of Patent: March 7, 1995

  • Patent number: 5144505
    Abstract: Movable members of a tape guide member for tape loading are disposed in plural numbers on both the upstream side and the downstream side of a tape running path with respect to a rotatable cylinder, or are disposed in plural number on at least either the upstream side or the downstream side. The plurality of movable members are disposed offset from each other in the radial direction of the rotatable cylinder. Tilt guides for converting the tape running direction are disposed between the associated movable members, and fixed to the stationary component side. A guide passage forming member along which the movable members are guided is also fixed to the stationary component side. Guide portions of the guide passage forming member are provided in plural number individually associated with the movable members. The guide portion nearer to the rotatable cylinder is set to always have a larger tilt angle than that of the outer guide portion with the plane of a tape cassette being a reference.

  • Patent number: 4937801
    Abstract: In a magneto-optical recording and reproducing apparatus for effecting the recording of information, etc. by irradiating a magnetic recording layer of a magneto-optical disk with a laser beam focued by an objective lens and applying a magnetic field to a portion of the magnetic recording layer irradiated with the laser beam, the strength of the magnetic field is controlled by a signal to drive the objective lens for focusing the laser beam onto the magnetic recording layer.

  • Patent number: 4130997
    Abstract: A refrigerator comprises a refrigerating cycle in which a refrigerant is charged and which includes a cooler for a freezing compartment, a closed loop which is branched from the refrigerating cycle and includes a cooler for a refrigerating compartment, and a heating device provided in the closed loop which supplies the refrigerant to the closed loop by means of vapor bubble pumping action, to thereby control the refrigerant flow in the closed loop.
