Latest Patents

Ohtani's latest patents include an innovative automotive air conditioning apparatus. This invention focuses on the on-off control of a compressor in a cooling mode of operation. The compressor control switch is actuated by a sensor that detects the engine's operating condition. During deceleration, the sensor creates an electrical path from the power source to the compressor, bypassing the control switch. This bypass is also activated when the vehicle is idling. If deceleration continues for a specified duration, a timer reconnects the compressor control switch to the power source. Additionally, an idling up circuit compensates for engine speed reduction caused by compressor activation during constant speed runs or while the vehicle is stationary. Another significant patent is a humidifying apparatus for air-conditioning equipment. This device includes a humidity detecting circuit and a spray nozzle, allowing for controlled humidity levels within the vehicle cabin.
