Publication number: 20240168405Abstract: Rotation of an image bearing member is started and stopped in a contact state between the image bearing member and a developing member. During post-rotation operation, a controller ends application of a charging voltage after changing the charging voltage stepwise to first and second charging voltages. The controller ends application of a developing voltage after changing the developing voltage stepwise at a developing position to first and second developing voltage in synchronism with the first and second charging voltages. A potential difference between each of surface potentials of first and second regions and an associated one of the first and second developing voltages is maintained within a predetermined range. The controller carries out control so that an absolute value of the surface potential of at least one of the first and second regions is made small by passing a current under application of a transfer voltage.Type: ApplicationFiled: November 17, 2023Publication date: May 23, 2024Inventors: YUSUKE SHIMIZU, TOMOO AKIZUKI, NORIHIRO SHIRAHATA, YUSUKE SAKAMOTO, SHUNSUKE MIZUKOSHI

Publication number: 20240094015Abstract: A route generation system includes a diagnosis unit, a generation unit, and an output unit. The diagnosis unit performs a diagnosis to estimate a deterioration degree of a road surface from an image to be monitored. The generation unit generates a travel route based on the deterioration degree of the road surface for each point diagnosed by the diagnosis unit and information regarding a road environment affecting the diagnosis for each point, the travel route being generated for capturing another image used for another diagnosis. The output unit outputs the generated travel route.Type: ApplicationFiled: March 16, 2023Publication date: March 21, 2024Applicant: NEC CorporationInventors: Yusuke Mizukoshi, Chisato Sugawara, Yoshihiro Nishikawa, Yuta Shimizu

Patent number: 7573171Abstract: A rotation control motor comprises a shaft, an armature having an armature core of which teeth are wound by wires to form coils, a commutator, and a field magnet. The armature core has a plurality of teeth, the commutator has a plurality of commutator segments corresponding to the number of teeth, and the coils comprise a normal coil and a brake coil. When the motor rotates faster than expected, the brake coil brakes the motor by magnetic flux, and the motor can rotate within a stable speed range.Type: GrantFiled: April 21, 2006Date of Patent: August 11, 2009Assignee: Igarashi Electric Works Ltd.Inventors: Naoto Sesita, Katuyuki Tanaka, Yusuke Mizukoshi, Hiroyuki Kurihara, Yoshihisa Watanabe

Patent number: 7511396Abstract: A motor comprises a yoke as casing, a shaft extending along a center of the yoke, an annular stator fixed to the yoke and an armature fixed to the shaft to rotate with the shaft inside the stator. The armature comprises a plurality of teeth on the outer circumferential surface. A wire is wound on any of the teeth to form a normal coil. Another wire is wound on another of the teeth to form a brake coil that is a short circuit. When the motor rotates much faster, the brake coil produces magnetic flux which acts as load against the rotation of the motor to allow the motor to rotate slower.Type: GrantFiled: April 19, 2006Date of Patent: March 31, 2009Assignees: Igarashi Electric Works Ltd., Mitsui Mining and Smelting Co., Ltd.Inventors: Naoto Sesita, Katuyuki Tanaka, Yusuke Mizukoshi, Hiroyuki Kurihara, Yoshihisa Watanabe, Hiroshi Sato

Patent number: 7478574Abstract: A motor shaft puts through a motor casing and a gear casing which are detachably connected to each other. In the motor casing, a rotor is fixed to the motor shaft, while a stator is fixed on the inner circumferential surface of the motor casing. The motor shaft has a worm which engages with a worm wheel in the gear casing. A collar in which the motor shaft is pressingly fitted is provided in the middle of the motor shaft at the end of the gear casing. The motor shaft is supported at each end of the worm in the gear casing.Type: GrantFiled: April 19, 2006Date of Patent: January 20, 2009Assignee: Igarashi Electric Works, Ltd.Inventors: Naoto Sesita, Katuyuki Tanaka, Yusuke Mizukoshi, Hiroyuki Kurihara, Yoshihisa Watanabe

Publication number: 20080116758Abstract: A motor comprises a rotor fixed to a shaft and a stator comprising a permanent magnet on the inner circumferential surface of a motor casing. The shaft extends from the opening end of the motor casing and has a worm wheel in a gear casing. The end face of the gear casing has an annular projection. The motor casing has an outward flange at the opening end. When the motor casing is connected with the gear casing, an elastic O-ring is fitted between a space formed by the outer circumferential surface of the annular projection, an outer vertical seat face of the gear casing and a corner of the outward flange thereby achieving suitable alignment of the motor casing with the gear casing. The permanent magnet is made of Nd magnet which is pressingly fitted on the inner circumferential surface of the motor casing.Type: ApplicationFiled: December 28, 2007Publication date: May 22, 2008Applicants: IGARASHI ELECTRIC WORKS LTD., MITSUI MININING AND SMELTING CO., LTD.Inventors: Naoto SESITA, Katuyuki TANAKA, Yusuke MIZUKOSHI, Hiroyuki KURIHARA, Yoshihisa WATANABE, Kazuhito YOKOMORI
