Patent number: 9207576Abstract: A toner conveying unit includes a toner case, an intermediate unit, and a developing unit. The intermediate unit removably supports the toner case. The intermediate unit includes a toner inlet, a toner outlet, a toner conveying path and a shutter. The toner outlet discharges the toner received from the toner inlet toward the developing unit. The toner conveying path connects the toner inlet with the toner outlet. The shutter opens/closes the toner inlet and the toner outlet in linkage with an operation of attaching/detaching the toner case. The shutter integrally includes an inlet sealing member capable of opening/closing the toner inlet, and an outlet sealing member linked with the inlet sealing member and capable of opening/closing the toner outlet.Type: GrantFiled: July 31, 2014Date of Patent: December 8, 2015Assignee: KYOCERA Document Solutions Inc.Inventor: Hiroaki Kitagawa

Publication number: 20150255315Abstract: A rinsing liquid adheres to a substrate subjected to a cleaning process. The rinsing liquid on the substrate is first replaced with IPA liquid. While the substrate covered with the IPA liquid is held in a dryer chamber, liquid carbon dioxide is supplied to the surface of the substrate. Liquid nitrogen is supplied to cool down the interior of the dryer chamber. This solidifies the liquid carbon dioxide on the substrate into solid carbon dioxide. Thereafter, the pressure in the dryer chamber is returned to atmospheric pressure, and gaseous nitrogen is supplied into the dryer chamber. Thus, the temperature in the dryer chamber increases. The solid carbon dioxide on the surface of the substrate is sublimated, and is hence removed from the substrate. All of the steps are performed while carbon dioxide is not in a supercritical state but in a non-supercritical state.Type: ApplicationFiled: May 20, 2015Publication date: September 10, 2015Applicant: DAINIPPON SCREEN MFG. CO., LTD.Inventors: Katsuhiko MIYA, Hiroaki KITAGAWA

Patent number: 9031473Abstract: Provided is an image forming apparatus including an apparatus main body, an operation member, a toner container, a shutter, and an interlocking mechanism. The operation member is a member for turning on and off a power supply of the apparatus main body, and takes an ON posture and an OFF posture. The toner container is a container configured to store the toner and including an opening section configured to allow communication between the inside and the outside of the container. The shutter can take an opening posture for opening the opening section and a closing posture for closing the opening section. The interlocking mechanism interlocks the posture of the operation member and the posture of the shutter to set the shutter in the opening posture when the operation member takes the ON posture and to set the shutter in the closing posture when the operation member takes the OFF posture.Type: GrantFiled: April 25, 2014Date of Patent: May 12, 2015Assignee: KYOCERA Document Solutions Inc.Inventor: Hiroaki Kitagawa

Publication number: 20030006607Abstract: A transparent sticker or dial with world major city marks printed converts an ordinary analog watch or clock to a world clock only by being attached on the face of a clock. The sticker is attached according to a rule that the standard time city mark comes to the 12 o'clock position. On the sticker sheet, other city marks are aligned along a circumference according to their time differences based on their global geographical location. A transparent dial with a marker at 12 o'clock position serves the same function. The dial is placed over the clock face in such a manner the marker comes to the designated position according the city whose local time is wanted. The short hand is read according to the overlaid clock dial. A chart can be used to know where the marker should be placed.Type: ApplicationFiled: May 21, 2002Publication date: January 9, 2003Inventors: Hiroaki Kitagawa, Chiyoko Kitagawa, Kaori Kitagawa
