Latest Patents

One of Sato's latest patents is for an air fuel ratio sensory system. This invention involves a method and apparatus for measuring atmospheric pressure in conjunction with an air-fuel ratio sensor. The sensor comprises a concentration cell with atmospheric air and exhaust electrodes on opposite sides of a solid-state electrolyte that has oxygen ion conductivity. During the atmospheric pressure measuring cycle, oxygen ions are pumped from the atmospheric air electrode to the exhaust electrode. This process can either be predetermined at a fixed value or sufficient to bring the cell to an equilibrium state. Atmospheric pressure is then calculated from the measured emf of the cell, utilizing an experimentally derived functional relationship. In a second embodiment, ions are pumped until a predetermined change of the concentration cell emf is achieved, determining atmospheric pressure based on the time required to achieve such change. The atmospheric pressure measuring mode operates on a time-shared basis with the air-fuel ratio detection mode.

Another notable patent involves a semiconductor acceleration sensor and vehicle control system. This sensor is formed by a cantilever with a conductive movable electrode at one end and at least one pair of fixed conductive electrodes located on opposing sides. To prevent the movable electrode from fusing to the fixed electrode, an insulating layer is provided between them. Additionally, the movable or fixed electrodes can be made from high melting point materials to enhance durability. The sensor detector unit processing circuit features digitally adjusted output characteristics through suitable switching of resistors. The sensor chip and detector unit integrated circuit may be housed in a hermetically sealed chamber to protect against environmental effects.
