Publication number: 20240103415Abstract: An image forming apparatus has an image forming unit to form a toner image on a first sheet and a fixing unit configured to heat the first sheet to fix the image to the first sheet. A control unit begins a cooling process for cooling the fixing unit when an overheating condition is met, then permits the image forming unit to form a toner image on a second sheet after the cooling process ends according to a first cooling condition if a person is detected near the image forming apparatus or after the cooling process ends according to a second cooling condition if a person not detected near the image forming apparatus. The cooling process under the first cooling condition ends in less time than under the second cooling condition.Type: ApplicationFiled: December 6, 2023Publication date: March 28, 2024Inventors: Masaya TANAKA, Hiroshi OTA

Patent number: 11679282Abstract: A treatment system can include a treatment instrument with an operation input element that has a magnet; and a sensor that detects a parameter that changes with a movement of the magnet together with the operation input element based on an operation of the operation input element. The treatment system can also include a control apparatus that can control the supply of electrical energy to the treatment instrument for operation of the treatment instrument. The control apparatus includes a processor that can determine a relationship between a change in a distance between the sensor and the magnet and a change in the parameter, and to set, based on the relationship, a threshold for switching between an ON state and an OFF state of the supply of the electrical energy to the treatment instrument.Type: GrantFiled: October 10, 2019Date of Patent: June 20, 2023Assignee: OLYMPUS CORPORATIONInventors: Tatsuya Suzuki, Hideo Sanai, Masaya Ota
