Publication number: 20230138270Abstract: An air conditioning controller according to an embodiment includes: a mechanical relay including a movable terminal, a stationary terminal, and a drive coil; a memory; and a processor. The air conditioning controller sends a control signal through the mechanical relay to an air conditioner. The processor performs boot processing for the air conditioning controller and energizes the drive coil to move the movable terminal to a predetermined position. The predetermined position is a position corresponding to transmission of a shutoff control signal for shutting off the air conditioner. At the boot processing, the processor does not move the movable terminal to the predetermined position if a switch avoidance condition is satisfied; otherwise, the processor moves the movable terminal to the predetermined position.Type: ApplicationFiled: October 27, 2022Publication date: May 4, 2023Applicant: DENSO WAVE INCORPORATEDInventor: Takahiro MIYAJIMA

Patent number: 11280520Abstract: In a gas hot water heater, changes of the signal output of an A/F sensor are calibrated in the atmosphere, in which the A/F sensor detects an oxygen concentration in a combustion tube. The gas supplied via a gas supply pipe is injected, together with in-taken air, into a combustion tube, which is incorporated in a hot water supply tank, via an injection unit. A proportional valve controls a combustion state in the combustion tube based on the detected oxygen concentration to thereby heat water supplied in the hot water supply tank. A purging process is performed to supply air into the combustion tube, at a timing between an extinguishment operation first performed after the ignition the gas mixture in the combustion tube and a re-ignition operation. Changes of signal output characteristics of the A/F sensor are subject to the calibration after the purging process.Type: GrantFiled: January 23, 2020Date of Patent: March 22, 2022Assignee: DENSO WAVE INCORPORATEDInventor: Takahiro Miyajima

Patent number: 10495617Abstract: A controller as a CO2 sensor reference value calibration apparatus calibrates a reference value of the CO2 sensor in the following manner. Introduction of outside air is started after a person is not detected. A CO2 concentration, which is acquired when a preset first waiting time elapses, is set as a provisional reference value. The carbon dioxide concentration, which is acquired when a preset second waiting time elapses, is compared with the provisional reference value. In a case where a change rate of the carbon dioxide concentration is out of a preset allowable range, the carbon dioxide concentration is acquired when the second waiting time elapses after newly setting the acquired carbon dioxide concentration as the provisional reference value. In a case where the change rate of the carbon dioxide concentration is in the allowable range, the currently set provisional reference value is set as the reference value.Type: GrantFiled: November 18, 2016Date of Patent: December 3, 2019Assignee: DENSO WAVE INCORPORATEDInventor: Takahiro Miyajima
