  • Patent number: 5246299
    Abstract: A cassette for holding a transfer printing film has a pressing member for pressing against a feed roll of the film wound around a feed reel in the cassette. When the cassette is loaded in a thermal transfer printer, the film is taken up around a take-up reel from the feed reel while the pressing member is applying a braking torque to the film on the feed reel so that torque balance is attained. When the wound length of the film of the feed roll has decreased to approximately 60 percent of the initial length, the pressing member ceases to apply the braking torque to the feed reel, and thereafter the feeding and taking up of the film are carried out in a regular torque state.

  • Patent number: 4873677
    Abstract: An apparatus for charging a power storage device provided within an electronic device. A power source provides direct current which is alternated in direction through a pair of primary coils for inducing alternating current in a secondary coil of the electronic device. The pair of primary coils are fixed to a coil yoke all of which are supported within a casing of the apparatus. During charging of the power storage device, the electronic device is mounted to the outside surface of the casing whereby substantially all of the magnetic flux of the magnetic field produced by the pair of primary coils flows through the secondary coil and coil yoke. The frequency of the oscillating signal is preset to provide the maximum induced current which will not adversely affect the movement of the analog mechanisms within the electronic device.

  • Patent number: 4491424
    Abstract: In an electronic analog timepiece an automatic sequence of events determines the proper magnitude of a detection resistor which is used in series with the motor coil so as to determine whether in normal operation the rotor is rotated or not when driven. A detection resistor is used in series with motor coil but only after a fixed time has passed from initiation of detection current flow. The detection resistor is logically variable and selected automatically in accordance with the motor's mechanical load at the time of switching on the power source or releasing the analog timepiece from a resetting operation. The resistance is formed part of the integrated circuit.
