Patent number: 4317188Abstract: A magnetic shielding plate for decreasing the affects of external magnetic flux fields on a step motor in an electronic wristwatch is provided. Specifically, the step motor includes a permanent magnet rotor and a magnetic permeable stator surrounding said rotor for incrementally rotating said rotor in response to changes in the magnetic orientation of said stator. A coil assembly includes an elongated coil core coupled to the stator and a coil wrapped around the elongated core for receiving timekeeping signals. A magnetic shield plate extends the lengthwise extent of the elongated core for shielding the coil core from external magnetic fields surrounding the wristwatch. The minimum cross-sectional area of the shield in the direction perpendicular to the elongated core, taken along the lengthwise extent of the core, defines the magnetic shielding characteristics of the shielding plate.Type: GrantFiled: June 16, 1980Date of Patent: February 23, 1982Assignee: Kabushiki Kaisha Suwa SeikoshaInventor: Kenichi Ushikoshi

Patent number: 4316274Abstract: The degenerating condition of the power source in an electronic timepiece, that is, a diminished battery voltage, is indicated to the user by unusual performance of the watch bands. Short periods of accelerated or decelerated hand movements alert the user to the battery condition. Persistent though intermittent unusual hand behavior distinguishes the battery life signals from malfunctions or poor timekeeping. A voltage detector circuit monitors the power source and on low voltage initiates the warning signals which are derived from the divider network of the timepiece. Mechanically resetting the hands to remove the visible effects or erratic hand movement, serves to reset the battery life detector circuits and repeat the warnings.Type: GrantFiled: January 29, 1979Date of Patent: February 16, 1982Assignee: Kabushiki Kaisha Suwa SeikoshaInventor: Kenichi Ushikoshi

Patent number: 4290129Abstract: Electronic circuits provide an indication on the face of an electronic wristwatch that battery voltage has diminished to a prescribed level and provide the same indication regardless of battery voltage by actuation of an external member. Multiple functions are activated by the same external member or members. The desired mode of operation is detected by the circuits dependent upon the position, sequence of operation and time duration in a selected position of an external member. In addition to a battery voltage operating mode, an alternative embodiment permits adjustment of minutes and hours without loss in second-hand accuracy. A counter memorizes elapsed time required for hand setting, and the second hand rapidly moves to its correct position after the hour and minute hands are set. The added function circuits are small, consume negligible power and have no adverse effect on battery life or design complexity.Type: GrantFiled: July 27, 1979Date of Patent: September 15, 1981Assignee: Kabushiki Kaisha Suwa SeikoshaInventor: Kenichi Ushikoshi
