  • Patent number: 10459402
    Abstract: In a cartridge employing an inclinable coupling member engaging with a rotational force transmitting portion of an electrophotographic image forming apparatus, the coupling member is configured to not engage with the rotational force transmitting portion of the electrophotographic image forming apparatus when the mounting and dismounting direction and the developing/spacing direction relative to the electrophotographic image forming apparatus are different from each other. A coupling lever is provided to contract and retract relative to the coupling member in interrelation with the mounting and dismounting operation of the cartridge, and a coupling spring for the coupling lever is provided to apply an urging force to the coupling member.

  • Patent number: 10369608
    Abstract: In a tool storing device handling a tool mounting stocker in which a punch and a die of a press brake are mounted in one stocker with rear surfaces facing each other, each of the stockers is supported on both sides by endless belts having one driving shaft, and the endless belts are circulated so that each of the supported stockers does not protrude to a worker side, whereby a position of a path line of the appropriate one of the stockers can be freely positioned at a position of the path line PL of a tool holder on the press brake side. This enables rapid and easy tool replacement by a bending robot by storing not only the tool made of the punch and the die but also the hand for the robot together.

  • Publication number: 20190195114
    Abstract: A controller estimates a first estimated adsorption amount which is an amount of adsorption of ammonia in the SCR catalyst at the time when the SCR catalyst is assumed to be in a predetermined abnormal state, estimates a second estimated adsorption amount at the time when the SCR catalyst is assumed to be in a predetermined normal state, calculates a first slip development temperature based on the first estimated adsorption amount, and calculates a second slip development temperature based on the second estimated adsorption amount. The controller, when carrying out an abnormality diagnosis based on a concentration of ammonia in an exhaust gas at the downstream side of the SCR catalyst, carries out diagnostic temperature control so as to control the temperature of the SCR catalyst to a temperature which is equal to or more than the first slip development temperature and is less than the second slip development temperature.
