Title: Innovations by Yoshio Tsutsumi
Introduction
Yoshio Tsutsumi is a notable inventor based in Hirakata, Japan. He has made significant contributions to the field of construction machinery through his innovative patents. With a total of 4 patents, Tsutsumi has developed technologies that enhance the efficiency and safety of construction operations.
Latest Patents
One of his latest inventions is a monitoring apparatus for a construction machine. This apparatus includes sensors that detect abnormal conditions at various predetermined inspection positions. A warning system works in conjunction with these sensors to provide an engine idling signal and a visual display based on the detected abnormality condition. The system features a delay circuit that activates the visual display only if the abnormality persists for a predetermined time after the engine idling signal is issued. The engine idling signal is triggered immediately upon detection of an abnormality, causing the engine to idle.
Another significant patent is the electric hydraulic control device for a construction vehicle. This device controls hydraulic cylinders of work tools in a construction vehicle. It features control valves that can be operated in two ways. For work tools that do not require smooth and fine control, the control valves are directly managed by an electric signal based on the operation levers' position. Conversely, for tools that necessitate precise control, the valves are managed through an electric servo mechanism, which responds to the lever's manipulation. Additionally, a detector ensures that the electric systems of all control valves are rendered inoperative when the transmission lever is locked.
