Title: Innovations of Yukio Ikehata
Introduction
Yukio Ikehata is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electronic timepieces, holding a total of 6 patents. His work has advanced the functionality and precision of timekeeping devices.
Latest Patents
One of his latest patents is an electronic timepiece operable in continuous and stepwise modes. This invention features a step motor driven by a circuit that selectively produces either continuous or stepwise hand-carrying pulses. The continuous hand-carrying pulses are generated by a waveform shaping circuit connected to a frequency divider, while the stepwise pulses are produced by a separate shaping circuit. The selection between these modes is managed by a hand-carrying mode selection circuit, which responds to a reset switch for the frequency divider.
Another significant patent is an electronic timepiece that includes a timepiece standard generator and a frequency divider with a resettable terminal. This device controls both an optically displaying device and a hand displaying device. It features a below second linking control circuit that detects the frequency divider's content and manages the synchronization of the time indications between the optically displaying device and the hand displaying device. This ensures that the time indications are linked within 0.5 seconds after adjustments.
