Publication number: 20240033681Abstract: A carbon dioxide recovery system includes a main controller and unit controllers. The main controller provides guidelines to the unit controllers for a plurality of recovery units. The guideline serves as a guideline for controlling operations of components including an electrochemical cell, a channel on/off valve, a pump, and a channel switching valve. Each one of the unit controllers determines a control content for each one of components based on the guideline.Type: ApplicationFiled: July 26, 2023Publication date: February 1, 2024Inventors: Hiroki AOSHIMA, Yousuke NAKAMURA, Hiroyuki TAKIKAWA

Publication number: 20240001294Abstract: In an adsorption mode, a control device applies an adsorption potential between a working electrode and a counter electrode only during an adsorption time. The adsorption time corresponds to a target carbon dioxide adsorption amount, which an adsorbent can adsorb. In a desorption mode, the control device applies a desorption potential only during a recovery time corresponding to a recovery amount. At this time, the control device acquires an optimum desorption time which is a desorption time associated with a carbon dioxide desorption amount equivalent to a target carbon dioxide recovery amount RVCO2 in a desorption amount change map data. Then, the control device applies the desorption potential only during the optimum desorption time in the desorption mode.Type: ApplicationFiled: June 26, 2023Publication date: January 4, 2024Inventors: HIROKI AOSHIMA, YOUSUKE NAKAMURA, HIROYUKI TAKIKAWA

Publication number: 20230338894Abstract: In a carbon dioxide recovery system. an electrochemical cell of a recovery device includes a working electrode having an adsorbent capable of adsorbing carbon dioxide, and a counter electrode paired with the working electrode. A sensor detects a recovery amount that is an amount of carbon dioxide recovered in the recovery device and sent to a carbon dioxide recovery tank. A controller applies a first potential between the electrodes only for an adsorption time period in an adsorption mode such that the adsorbent adsorbs carbon dioxide. The adsorption time period corresponds to a target adsorption amount that is an amount of carbon dioxide that can be adsorbed by the adsorbent. The controller applies a second potential between the electrodes in a recovery mode such that the adsorbed carbon dioxide is desorbed. The controller acquires the target adsorption amount as a correlation value correlated with the detected recovery amount.Type: ApplicationFiled: April 5, 2023Publication date: October 26, 2023Inventors: HIROKI AOSHIMA, YOUSUKE NAKAMURA, HIROYUKI TAKIKAWA

A sensor detects a recovery amount of carbon dioxide recovered and sent to a carbon dioxide recovery tank. A controller applies a first potential between the electrodes only for a time period in an adsorption mode. The time period corresponds to a target amount of carbon dioxide that can be adsorbed by the adsorbent. A storage unit stores multiple adsorption-amount change data indicating association between the target amount and the time period. The controller acquires the target amount correlated with the detected recovery amount, acquires the time period by using the acquired target amount, and selects data from among the multiple adsorption-amount change data according to the recovery amount as in-use data for acquisition of the time period.Type: ApplicationFiled: April 5, 2023Publication date: October 26, 2023Inventors: HIROKI AOSHIMA, YOUSUKE NAKAMURA, HIROYUKI TAKIKAWA

Publication number: 20220341240Abstract: An opening-closing member controller includes a control unit that executes an initialization process to store at least a fully closed position of an opening-closing member. In the initialization process, the control unit closes the opening-closing member, executes entrapment reversing control one or more times when entrapment is detected to open the opening-closing member, and closes the opening-closing member after the entrapment reversing control to store a position where the opening-closing member locks as the fully closed position.Type: ApplicationFiled: June 16, 2020Publication date: October 27, 2022Applicants: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hiroki AOSHIMA, Akiyoshi OHARA, Ryo MIYAZAKI, Kenji KANEKO, Tsuyoshi SUGIMOTO, Toshihiro GOTOU, Hideki MAEDA

Patent number: 11142940Abstract: An open-close body controller includes a motor, movement interference determination unit, and disturbance determination unit. Motor is configured to open and close an open-close body of vehicle. Movement interference determination unit is configured to detect whether characteristic value of motor, which is varied in accordance with change in load applied to open-close body when moving, is in movement interference range or non-movement interference range bordering threshold value and determine that movement of open-close body has been interfered with by foreign object when characteristic value is in movement interference range. Disturbance determination unit is configured to determine whether motor is subject to effect of disturbance.Type: GrantFiled: October 30, 2019Date of Patent: October 12, 2021Assignee: DENSO CORPORATIONInventor: Hiroki Aoshima

Patent number: 10815714Abstract: An opening/closing member driving device includes a motor that opens and closes an opening/closing member and a controller configured to perform an abnormality determination process and a masking process. The abnormality determination process determines occurrence of a foreign object being entrapped or caught by comparing driving information corresponding to a driving status of the motor to a predetermined threshold value. The masking process invalidates the abnormality determination process over a predetermined masking period when the motor is activated. The controller includes a correction unit. The correction unit corrects at least one of the masking period or the threshold value when the motor is activated in a direction opposite to that of a preceding operation in a state in which the opening/closing member is in a high-load range.Type: GrantFiled: July 12, 2017Date of Patent: October 27, 2020Assignee: DENSO CORPORATIONInventor: Hiroki Aoshima

Patent number: 10060171Abstract: In a power window apparatus, when a controller determines that a captured foreign object, which is captured between a window glass and a window frame of a door, is present, the controller executes an interrupting process that interrupts a current operation of a drive mechanism. The controller does not determine whether the captured foreign object is present in an initial mask period that is a time period from a time point of starting rotation of the electric motor to a time point, at which a rotational speed of the electric motor reaches a stable state. The initial mask period is variable based on an operational load of the electric motor.Type: GrantFiled: November 25, 2015Date of Patent: August 28, 2018Assignee: DENSO CORPORATIONInventor: Hiroki Aoshima
