Latest Patents

One of Ohtani's latest patents is a rotary pointer display device. This innovative device automatically adjusts the starting position of the needles when displaying operational settings and measurements, even in cases of battery exchange or needle drive process errors. The display can show physical quantities using pointers that move above scale plates. It features a memory that stores the movement destination position of the pointers, and a controller generates instructions to calculate the movement destinations after the electrical supply voltage stabilizes. This design minimizes the number of instructions needed for automatic movement while allowing the pointers to follow operator controls seamlessly.

Another significant patent is a camera display device with reduced display time. This needle-type display device is designed for displaying photographic data in cameras. It allows indicating needles to move directly from currently displayed values to new values without returning to an origin position. The device includes a half-press switch that operates a rangefinder and photometric unit, displaying photographic data based on the movement from an origin position. This innovation reduces the time required for the display needles to move, enabling a quick response to measured photographic data.
