Patent number: 11947300Abstract: An image forming system includes an image forming apparatus, a cutting apparatus, and a controller. The cutting apparatus includes a conveyance path, a first cutting unit configured to cut, at a cutting position with respect to a conveyance direction of the sheet on the conveyance path, the sheet in a width direction perpendicularly intersecting with the conveyance direction, and a second cutting unit configured to cut, at a cutting position with respect to the width direction, the sheet in the conveyance direction. The controller is configured to control the cutting apparatus such that, in a case where the sheet is cut neither with the first cutting unit nor with the second cutting unit, the sheet is conveyed through the conveyance path with the first cutting unit and the second cutting unit retreated not to contact with the sheet passing through the conveyance path.Type: GrantFiled: June 30, 2022Date of Patent: April 2, 2024Assignee: Canon Kabushiki KaishaInventors: Atsushi Takada, Tadashi Iwakawa, Rin Ishikawa

Patent number: 11946992Abstract: In one embodiment, an MRI system includes at least one magnetic field assembly and at least one image generator. The at least one magnetic field assembly includes an open main magnet configured to generate a main magnetic field for dominantly determining a magnetic resonance frequency, a gradient coil configured to generate a gradient magnetic field, and an RF coil configured to generate a radio frequency magnetic field. The at least one image generator is configured to generate a magnetic resonance image of an object by using the main magnetic field, the gradient magnetic field, and the radio frequency magnetic field generated by the at least one magnetic field assembly. The main magnet is disposed between adjacent examination rooms. The main magnetic field generated by the open main magnet is commonly used in each of the adjacent examination rooms.Type: GrantFiled: March 30, 2022Date of Patent: April 2, 2024Assignee: CANON MEDICAL SYSTEMS CORPORATIONInventors: Misaki Hattaha, Sadanori Tomiha

Patent number: 11947290Abstract: An image forming apparatus includes first and second rotatable members forming a nip therebetween, a heater disposed in inside of the second rotatable member, a first temperature sensor provided on a center of the heater, a second temperature sensor provided on an end side of the heater. A controller controls a feeding interval in which a trailing edge of a preceding sheet passes through the nip until a leading edge of a subsequent sheet reaches the nip. The controller controls the feeding interval to be a first interval in a case which a feeding speed of the sheet is a first speed and a detected temperature by the second sensor is a first temperature, and to be a second interval shorter than the first interval in a case which the feeding speed is a second speed lower than the first speed and the detected temperature is the first temperature.Type: GrantFiled: August 5, 2022Date of Patent: April 2, 2024Assignee: Canon Kabushiki KaishaInventors: Atsushi Nakamoto, Kazuhiro Doda
