Latest Patents
One of Iguchi's latest inventions is a pressure transducer designed for automobiles. This device features a closed housing and a member that detects pressure in the engine's suction pipe, converting the detected pressure into electric signals. An amplification circuit is also included within the closed housing, along with an air passage that communicates with the atmosphere while preventing water from entering the housing. The air passage is designed with an air hole that is strategically placed around the terminals for leading electric signals out of the housing.
Another significant invention by Iguchi is a vacuum-operated device. This device consists of a first vacuum chamber defined by a part of the casing and a first diaphragm, as well as a second vacuum chamber defined by the first diaphragm, another part of the casing, and a second diaphragm. The first vacuum chamber connects to a vacuum source, while the second vacuum chamber can also connect to the vacuum source through a changeover valve. This allows the second vacuum chamber to be subjected to either vacuum or atmospheric pressure. The device includes a rod that is secured to both diaphragms, enabling axial movement based on their movements. Additionally, the device is equipped with springs that provide opposing forces to the diaphragms and rod, allowing for different modes of movement and spark advance characteristics.
