Latest Patents

One of Iguchi's latest patents is for a "Current limited pulse width modulation controlled motor." This invention aims to maintain a consistent pressure of fluid delivered from a pump at a target value without incurring additional costs. The pump control unit features a driver control unit that regulates the rotational speed of a hydraulic pump by adjusting the duty ratio of a PWM signal that drives the excitation coils of an electric motor. Additionally, the pump control unit includes a signal correction circuit that converts the current flowing in the excitation coils into a voltage signal using a shunt resistor. This circuit also divides the voltage signal with a voltage division ratio setting circuit, which shortens the ON signal of the PWM signal by increasing the divided voltage. The voltage division ratio setting circuit is designed to set the divided voltage higher as the ON period of the PWM signal increases.

Another notable patent is for a "Fixing member." This invention comprises a case member that includes a substrate supporting member designed to support a substrate and is integrally provided with a connector. A cap member is fixed to the case member, and an external force transmitting portion extends from the substrate supporting member to the cap member. This portion transmits any external force applied to the connector to the cap member while the case member remains fixed to the cap member.
