Title: Innovations of Hiroyuki Tsuru

Introduction

Hiroyuki Tsuru is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of display technology, holding a total of 15 patents. His work primarily focuses on enhancing the functionality and reliability of pointer-type display devices.

Latest Patents

One of Tsuru's latest patents is the Rotary Pointer Display Device. This invention addresses the challenges of displaying operational settings and measurements on pointer-type display devices. It features an automatic adjustment mechanism for the starting position of the needles, even during battery exchanges or needle drive process errors. The device can display physical quantities using pointers that move above scale plates. It ensures that the display is automatically corrected despite changes in electric supply loading, battery exchanges, or voltage drops. A memory component stores the movement destination of the pointers, while a controller generates instructions for their movement after stabilizing the electrical supply voltage. This innovation minimizes the number of instructions needed for automatic movement while allowing the pointers to follow operator controls seamlessly.

Another notable patent is the Rotating Indicator Pointer Type Display Apparatus. This display apparatus includes a rotating indicator pointer that conveys information through rotational movement. It features an operating device that can be manipulated in two ways to rotate the indicator pointer. The drive control device ensures that the pointer rotates in the same direction, regardless of how the operating device is engaged.
