  • Patent number: 10551343
    Abstract: Provided is a method of inspecting an assembly defect of a gas sensor in a mass-production process. The sensor element included in a second constituting member includes a heater therein and an electrode terminal for a heater in its surface, and the first constituting member includes a contact point member contacting the terminal in a state where the sensor element is inserted into its opening. A first heater resistance value before incorporated is measured to associate the resistance value with an identification information of the sensor element, a second heater resistance value is measured via a contact point member, in a state where the first and second constituting members are integrated with each other, to associate the resistance value with the identification information of the sensor element, and when a difference value between these resistance values associated with the identical identification information exceeds a threshold value, it is determined that an assembly defect occurs.

  • Patent number: 10292251
    Abstract: An X-ray inspection device achieves a high cooling effect without using an expensive air conditioner and is excellent in cleaning property. The inside of a first case of an X-ray inspection device is separated into plural cooling partitions by separation walls by the use limit temperature and the like, and heat sources respectively having intrinsic use limit temperature are stored in respective partitions. Because a flow passage of air is set inside the cooling partition so that the heat sources having low use limit temperature are disposed upstream of the heat sources having high use limit temperature, the cooling efficiency is excellent. A heat absorption member of a heat exchange device exists inside the first case, and a heat radiation member exists inside a second case communicating with the external air. Because there is no protrusion of the heat radiation member as the total cases, cleaning property is excellent.

  • Patent number: 9683959
    Abstract: A method for setting a temperature rising profile of a sensor element in the activation of a gas sensor is capable of quickly increasing the temperature of the sensor element while reliably preventing or reducing the occurrence of a crack. The method includes Weibull plotting a failure rate that is a cumulative frequency at which a crack occurs as a result of the rapid temperature rising of the sensor element, identifying a temperature-rising-rate upper limit from the plotting results, determining, based on the temperature-rising-rate upper limit, a temperature-rise upper limit curve, and determining, as an appropriate function, a temperature rising profile in a range in which a temperature rising rate at an appropriate temperature does not exceed values on the temperature-rising-rate upper limit curve for the temperature.

  • Patent number: 9446368
    Abstract: A mixing device used in a fluidized catalytic cracking apparatus which mixes feed and a catalyst includes a cylindrical reaction container which supplies a catalyst in a vertical direction; a plurality of feed injection nozzles arranged along an outer circumference of the reaction container; and a catalyst flow regulator which is provided in the reaction container and regulates a flow of the catalyst in the vicinity of the feed injection nozzles. The catalyst flow regulator has no feed supply function and forms a catalyst moving bed having a hollow tubular shape which is coaxial with the reaction container in the vicinity of the feed injection nozzles. The catalyst flow regulator can effectively prevent backward flow of injected fuel. Although the mixing device has a simple structure, it has a high cracking rate and maintenance of the fluidized catalytic cracking apparatus can be performed easier.
