  • Publication number: 20220144562
    Abstract: Whether to permit or prohibit drive of at least one object, out of a slider and a movable linear module, is determined based on position related information on position of the slider or the movable linear module before the drive of the object is started. In this way, in a linear conveyor system for transferring the slider between a plurality of fixed linear modules using the movable linear modules, the occurrence of interference between the linear modules and the slider can be suppressed.

  • Patent number: 7849674
    Abstract: A NOx reduction catalyst and an ammonia slip oxidation catalyst are disposed in an exhaust system in this order, and also, an electric fan is disposed on piping which communicates an upper space of a storage tank storing therein a reducing agent with the exhaust upstream of the NOx reduction catalyst. Then, when the temperature of the ammonia slip oxidation catalyst reaches or exceeds the temperature for activating a catalyst thereof, the electric fan is operated for a predetermined period of time, so that the gas (ammonia series gas) in the upper space of the storage tank is forcibly discharged to the upstream side of the NOx reduction catalyst. Further, a discharge-forcing device, such as an electric fan or the like, forcibly discharging the gas in the upper space of the storage tank, an adsorbing device temporarily adsorbing thereto the forcibly discharged gas and an oxidation catalyst oxidizing the gas desorbed from the adsorbing device, may be disposed to the storage tank in this order.

  • Patent number: 7703276
    Abstract: Clogging of an injection nozzle which supplies a reducing agent to the exhaust gas on an upstream side of a reduction catalyst in the exhaust gas passage is prevented, and the efficiency of NOx purification processing is improved. A reducing agent supply unit uses a detection signal of the exhaust gas temperature from a temperature detection device to set a supply quantity at or above a lower limit for cooling the interior of an injection nozzle to below the temperature at which urea water crystallizes, for the detected exhaust gas temperature, and supplies urea water to the injection nozzle at the set supply quantity. By such supply of urea water, the interior of the injection nozzle is cooled to below the temperature at which the urea water crystallizes. As a result, the urea water does not crystallize inside the injection nozzle, and clogging of the injection nozzle can be prevented.

The holding member includes a holding plate; an even number of pinions meshed with each other and supported by the holding plate so as to be rotatable; and guiding components supported by the holding plate. The pinions, disposed between the guiding components, are meshed with the racks, and the guiding components are engaged with the guiding portions so as to be slidable. The biasing direction in which the toggle biases the holding member is reversed substantially at the midpoint of the movable range of the holding member.

  • Patent number: 7562521
    Abstract: The flow of exhaust gas flowing through the SCR muffler becomes good, thus improving the efficiency of purging nitrogen oxide (NOx) contained in exhaust gas. Further, vibrations that are caused by vibrations of the vehicle, exhaust gas, and the like, to which a reducing agent, etc., supplying nozzle is subject, are suppressed or reduced, thus improving the efficiency of an SCR catalyst purging nitrogen oxide (NOx) and the durability of the reducing agent, etc., supplying nozzle. The SCR muffler comprises an SCR catalyst 1 for selectively reducing and purging nitrogen oxide (NOx) contained in exhaust gas; an exhaust pipe 2 that allows the exhaust gas to flow into the SCR catalyst; and a reducing agent, etc., supplying means 3 that supplies a reducing agent or a reducing agent precursor to the exhaust gas. A plate 4 having air holes 5 which disperse and make a flow of the exhaust gas uniform is provided downstream of the reducing agent, etc., supplying means and upstream of the SCR catalyst.
