Publication number: 20140376963Abstract: In connection with movement of an opening-closing member when a toner accommodating container is attached to the image forming apparatus, the urging direction of an urging member relative to the opening-closing member changes from a direction that causes the opening-closing member to close an opening portion to a direction that causes the opening-closing member to open the opening portion. By using the urging force of the urging member that acts in the direction that causes the opening-closing member to open the opening portion, the toner accommodating container is pulled into the image forming apparatus.Type: ApplicationFiled: June 20, 2014Publication date: December 25, 2014Inventor: Kazushi Suzuki

Patent number: 8890459Abstract: A motor control device with which both high-accuracy current detection and improvement in voltage utilization factor are achieved is provided. When an ON time of any one of low potential side switching elements corresponding to respective phases in a driving circuit is shorter than a detection time of a current value, a microcomputer estimates a phase current value of a current undetectable phase based on current values of two phases other than the current undetectable phase corresponding to the said FET. Then, at the time of current detection using the blind correction, during current detection for two phases, other than the current undetectable phase, based on which the blind correction is performed, motor control signals for maintaining switching states of a switching arm corresponding to the current undetectable phase are output.Type: GrantFiled: March 10, 2010Date of Patent: November 18, 2014Assignee: JTEKT CorporationInventors: Atsuo Sakai, Tsutomu Matsumoto, Kazushi Suzuki

Patent number: 8878720Abstract: To detect an abnormal value in a satellite positioning system with high precision even when the observation environment changes or there is the time series correlation between data. An abnormal value index calculation unit 11 calculates an abnormal value index at each time of time-series data such as a pseudo distance between each artificial satellite and a receiver in the satellite positioning system or the like. A dynamic model forming unit 12 dynamically forms a model from the abnormal value index in a predetermined period and calculates a change point index from the time-series abnormal value index based on the dynamic model. The change point index is an index for determining whether the time-series is a one-shot outlier from a dynamic model or the dynamic model itself of input data changes when the time-series value which suddenly increases and decreases exists.Type: GrantFiled: February 25, 2011Date of Patent: November 4, 2014Assignee: NEC CorporationInventors: Takeshi Ono, Kazushi Suzuki, Takayuki Kaneso, Takayuki Nakata, Kenji Aoki

Patent number: 7785980Abstract: An object of the present inventions is to overcome a problem that the presence of a metal film, which is opaque to a visible light, between a lower layer alignment mark and a photoresist prevents the detection of the lower layer alignment mark, to make the pattern formation difficult. In the present inventions, an insulating film is placed beneath the alignment mark in structure; an alignment mark consisting of said multi-layered film comprising an alignment mark layer and the insulating film, which constitutes a stepped part with an increased difference in level, is first formed, inside a mark hole, in a manner of self-alignment; and then the metal film which is the very cause of the above problem is formed thereon. Since the metal film itself has a stepped shape corresponding to the alignment mark, alignment can be made with great accuracy.Type: GrantFiled: May 15, 2007Date of Patent: August 31, 2010Assignee: Elpida Memory, Inc.Inventor: Kazushi Suzuki
