Patent number: 9926140Abstract: There is provided a roller conveyor that has a function capable of specifying a failure part or a defective part. When a signal for executing a failure detection operation is transmitted from a host controller (50) to each zone controller (10), each zone controller (10) immediately activates the corresponding motor-incorporating roller (5a). Then, after a certain time, the motor-incorporating roller (5a) is stopped. A pulse interval thereafter is detected by a pulse interval monitoring program (36) to determine whether a delay phenomenon has occurred. The delay phenomenon is a phenomenon in which the pulse signal generation interval is temporarily extended.Type: GrantFiled: April 30, 2014Date of Patent: March 27, 2018Assignee: Itoh Denki Co., Ltd.Inventors: Kazuo Itoh, Toshiyuki Tachibana, Yoshinori Nagai, Shinji Sayama

Publication number: 20110033360Abstract: Provided is a method of operating a hydrolytic separator in which ammonia gas to be used as a reducing agent in a flue gas denitrization apparatus is generated by the hydrolysis of an aqueous urea solution. When the hydrolytic separator is started and ammonia gas injection is initiated, the hydrolytic separator is operated in a constant-pressure mode in which the internal pressure of the hydrolytic separator is kept constant regardless of the increasing temperature of the hydrolytic separator. Thereafter, the constant-pressure operation is switched to a variable pressure operation in which the pressure is raised as the temperature of the hydrolytic separator rises. In the method, the constant-pressure operation is switched to the variable pressure operation after the temperature of the hydrolytic separator in the constant-pressure operation has reached or exceeded the variable pressure operation temperature corresponding to that pressure.Type: ApplicationFiled: May 27, 2009Publication date: February 10, 2011Applicant: BABCOCK-HITACHI KABUSHIKI KAISHAInventors: Satoru Shishido, Tooru Ogasahara, Yoshiyuki Takeuchi, Yoshinori Nagai
