Patent number: 11952239Abstract: A sheet feeding device includes a feeding roller pair, a detecting portion, a first changing portion, a second changing portion, and a controller for controlling the first changing portion and the second changing portion. The controller starts a first feeding operation for feeding a sheet toward the obliquely feeding roller pair in a nipping state of the feeding roller pair and then starts a second feeding operation for feeding the sheet for abutting a side end of the sheet against the reference member in the nipping state of the obliquely feeding roller pair. The controller changes, after the first feeding operation is started and before the second feeding operation is started, a start timing of the second feeding operation on the basis of a detection result of a position of the side end of the sheet detected by the detecting portion.Type: GrantFiled: December 1, 2021Date of Patent: April 9, 2024Assignee: Canon Kabushiki KaishaInventors: Yoshinao Chiba, Shingo Iwami, Koji Suzuki, Yuma Inui, Yoshiya Numata

Patent number: 8253096Abstract: There is provided a time-of-flight mass spectrometer of a simple configuration and low cost that prevents temperature drift and provides stable mass spectrum without the use of expensive Invar material for the flight tube which nevertheless is not easily affected by external vibrations and does not deflect under its own weight when held as a cantilever. The flight-tube is made of a CFRP pipe 17a whose inner and outer surfaces are provided with an electroless nickel-plated layer 17b as an electroconductive treatment. Electroconductive adhesive 21 is used for joining to flight-tube holding member 18. Unlike previous flight-tubes made of metal, flight-tubes made of CFRP pipe 17a do not deform even when no temperature adjustment and control system is used. Also, since the specific gravity of CFRP is only about one-fifth of that of stainless steel, the flight-tube does not easily deflect even when it is held as a cantilever.Type: GrantFiled: May 31, 2011Date of Patent: August 28, 2012Assignee: Shimadzu CorporationInventor: Koji Numata

Patent number: 7482988Abstract: An antenna is mounted in a vehicle for receiving a radio wave of a specified wavelength, and an electronic device such as a meter device is mounted in the vehicle. The electronic device tends to generate radiation noise when being operated. To reduce reception of the radiation noise by the antenna, a passive conductor element is located between the antenna and the electronic device to reflect a part of the radiation noise. The passive element is away from the electronic device by a distance that is about multiple times of one-quarter of the specified wavelength and is about multiple times of one-half of the specified wavelength in length.Type: GrantFiled: October 16, 2006Date of Patent: January 27, 2009Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Yuji Sugimoto, Toshihiro Hattori, Toru Yamazaki, Koji Numata, Masaaki Hisada
