Patent number: 9669639Abstract: A post-processing liquid application device includes an ejecting head that ejects a post-processing liquid in a specific ejection pattern on a recording medium after ink has been attached thereto to form a character and/or an image based on image information, and a control unit that selects the specific ejection pattern based on a coverage rate calculated from the image information. When the coverage rate is low, the control unit selects a first ejection pattern for ejecting the post-processing liquid on a printed portion of a print region of the recording medium or ejecting the post-processing liquid on the printed portion and a surrounding portion thereof. When the coverage rate is high, the control unit selects a second ejection pattern for ejecting the post-processing liquid over the entire surface of the print region of the recording medium.Type: GrantFiled: August 10, 2016Date of Patent: June 6, 2017Assignee: Ricoh Company, Ltd.Inventors: Satoru Nagasawa, Yoshinari Suzuki

Patent number: 8851645Abstract: A liquid container contains liquid to be supplied to a body of an image forming apparatus. The liquid container includes a liquid supply port part having a liquid supply port supplying the contained liquid and a cap member mounted on the liquid supply port part. The cap member has a sealing part sealing the liquid supply port and a holding part holding an information storage device storing information concerning the liquid. The sealing part and the holding part are separably connected together. When the cap member is mounted on the liquid supply port while the sealing part and the holding part are connected, the holding part is immovably fixed to the liquid supply port via the sealing part. When the sealing part has been separated from the holding part, the holding part comes to be able to move with respect to the liquid supply port.Type: GrantFiled: April 9, 2013Date of Patent: October 7, 2014Assignee: Ricoh Company, Ltd.Inventors: Satoru Nagasawa, Tomonori Tamura

Patent number: 8764063Abstract: A steering device contains a rolling bearing that axially supports a steering shaft to allow rotation, and whose upper column and lower column engage along the axis in a sliding motion in order to provide improved steering wheel operating stability during high-speed driving. The elastic force of an O-ring tightens the outer circumferential surface of a female steering shaft against the cylindrical surface of a bushing. A specific frictional force therefore occurs between the cylindrical surface of the bushing and the outer circumferential surface of the female steering shaft so that handling stability of the steering wheel during high-speed driving is improved. Moreover, vehicle vibrations are prevented from being conveyed to the steering wheel by the O-ring crushed due to the pressing force of the inner circumferential surface of the first lower column and that absorbs the vibration of the female steering shaft.Type: GrantFiled: January 18, 2012Date of Patent: July 1, 2014Assignee: NSK Ltd.Inventors: Masaya Jouta, Satoru Nagasawa
