Patent number: 10900905Abstract: A needle-shaped body protrudes from a cantilever made of Si. Furthermore, the rear face of the cantilever is coated with aluminum (first metal) having a Fermi level higher than that of Si. The cantilever is dipped into an aqueous silver nitride solution containing the ions of Ag serving as a second metal. The electrons of Si flow out to the aqueous silver nitride solution due to the existence of the aluminum, and Ag nanostructures are precipitated at the tip end of the needle-shaped body. A probe for tip-enhanced Raman scattering in which the Ag nanostructures are fixed to the tip end of the needle-shaped body is manufactured. The sizes and shapes of the Ag nanostructures can be controlled properly by adjusting the concentration of the aqueous silver nitride solution and the time during which the cantilever is dipped into the aqueous silver nitride solution.Type: GrantFiled: June 30, 2017Date of Patent: January 26, 2021Assignees: HORIBA, LTD., KYOTO UNIVERSITYInventors: Masayuki Nishi, Kazuyuki Hirao, Daisuke Teranishi, Hiroki Itasaka, Nobuyuki Naka, Yoshito Okuno, Shinsuke Kashiwagi, Yasushi Nakata

Patent number: 8045891Abstract: In a rotary type image developing apparatus that has a rotary rack accommodating a plurality of developer units and drives the rotary rack to rotate in a predetermined rotational direction so as to bring a targeted one of the developer units to a developing position, each developer unit includes a toner storage in which a first slope is disposed. As the rotary rack rotates, toner that remains upstream of a toner supply opening in a toner flowing direction in the toner storage is guided by a slope surface of the first slope, which enables the toner to be smoothly supplied to a developing chamber. Thus, even when the toner gets low, the toner can be efficiently supplied from the toner storage to the developing chamber with the aid of the first slope.Type: GrantFiled: April 14, 2008Date of Patent: October 25, 2011Assignee: Konica Minolta Business Technologies, Inc.Inventors: Masayuki Nishi, Tsugihito Yoshiyama

Patent number: 7853179Abstract: In an image forming apparatus provided with a rotary type image developing apparatus, during monochrome print job processing, it is judged whether the amount of toner remaining in the developing chamber of the black developer unit is equal to or less than a predetermined amount M. If the judgement is affirmative, (i) the monochrome print job is suspended, (ii) the rotary rack is rotated to stop the black developer unit at the toner supply position temporarily, and is moved to the developing position again, and (iii) the monochrome print job is resumed. With the stated structure, the toner can be steadily supplied even when the amount of toner remaining in the developing chamber gets low during executing monochrome print jobs.Type: GrantFiled: June 26, 2008Date of Patent: December 14, 2010Assignee: Konica Minolta Business Technologies, Inc.Inventor: Masayuki Nishi
