Patent number: 11821159Abstract: Provided are a reinforcing member and a construction method capable of easily securing a side wall contact height even in the case where installed equipment is provided on a side wall. A reinforcing member according to the present invention is a reinforcing member which reinforces a manhole by being fixed to the manhole in a state in which at least part of the reinforcing member is in contact with a side wall inner surface of an inner surface of the manhole, an insertion hole into which an anchor bolt provided to protrude from the inner surface of the manhole can be inserted is formed, and the insertion hole is an elongated hole which allows the reinforcing member to move relative to the anchor bolt in an inserted state in which the anchor bolt is inserted into the insertion hole and an unfixed state in which the reinforcing member is not fixed to the manhole.Type: GrantFiled: March 26, 2019Date of Patent: November 21, 2023Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Norihiro Fujimoto, Tomoyasu Nagai, Shunsuke Tsuda, Takashi Sugiura

Patent number: 9662921Abstract: A recording medium including a substrate and an ink receiving layer on the substrate, the ink receiving layer containing inorganic particles and a water-soluble resin. The recording medium has an HM1 of 40 N/mm2 or less and has a rate of change of HM2 to HM1 of 400% or less. HM1 is a Martens hardness when an indenter is pushed at a 500 mN load over 180 seconds from a surface of the recording medium into a 1 ?m depth in a thickness direction thereof.

Patent number: 8768193Abstract: A fixing apparatus capable of reducing deterioration in productivity while preventing a fixing roller from being heated to a high temperature. The fixing roller has a heating unit incorporated therein, and a rotatable pressurization roller abuts on the fixing roller. A thermistor detects a surface temperature of the fixing roller. A fixing operation is controlled by selectively switching between a first mode and a second mode in which the number of sheets subjected to fixing per unit time is smaller than in the first mode. One of the first and second modes is selected based on a first temperature detected by the thermistor at a first time, a second temperature detected by the thermistor at a second time, and a minimum temperature of the fixing roller at which the toner image can be fixed.Type: GrantFiled: October 7, 2011Date of Patent: July 1, 2014Assignee: Canon Kabushiki KaishaInventor: Takashi Sugiura
