Title: **Hideo Karasawa: Innovator of Construction Machinery Control Systems**
Introduction
Hideo Karasawa, an accomplished inventor based in Tsuchiura, Japan, has made significant contributions to the field of construction machinery with a total of 16 patents to his name. His work focuses primarily on developing innovative control systems that enhance the efficiency and effectiveness of construction operations.
Latest Patents
Among Karasawa’s latest patents is a cutting-edge construction machine controller. This invention includes a storage section that retains a first relationship between manipulated variables of an operating lever, which is preset for each vehicle-body weight and target delivery pressures of a hydraulic pump. The controller’s target delivery pressure computation section plays a crucial role, applying the vehicle-body weight and manipulated variable inputs to calculate the target delivery pressure of the hydraulic pump accurately. Furthermore, a feedback control section ensures that the delivery pressure aligns with the calculated target, leading to improved operational reliability.
Another significant patent focuses on a control unit for construction machinery. This invention features a target speed setting section that establishes an idle engine speed lower than an input speed when no operating signal is detected from the control lever over a specified period. The speed control section then maintains optimal engine performance by adjusting the idle speed according to environmental conditions, thereby preventing performance reductions during transitions from auto idle states.
