20100070240 | DIAGNOSTIC MECHANISM IN DIFFERENTIAL PRESSURE TYPE MASS FLOW CONTROLLER - This invention provides a diagnostic mechanism of a differential pressure type mass flow controller comprising a diagnostic parameter calculating section that obtains a mass flow rate integrated value by means of an integrating calculation from the lowering pressure value of an inlet side sensor among the inlet side sensor and an outlet side sensor arranged in communication respectively at the inlet side and the outlet side of a differential pressure generating resistive element that generates a differential pressure between the inlet and the outlet by changing a flow rate control valve arranged on the channel where a fluid flows from a flow rate control state to a closed state, and further obtains a diagnostic volume value from the obtained mass flow rate integrated value, and a comparing section that compares the diagnostic volume value obtained at the diagnostic parameter calculating section with a specified volume value. | 03-18-2010 |
20120080104 | DIAGNOSTIC MECHANISM - A diagnostic mechanism includes: a flow rate control part configured to control an opening degree of a flow rate control valve provided in a flow passage so that a measurement flow rate value outputted from a flow rate sensor becomes a target flow rate value; an inspection value output part configured to output an inspection value related to a time integral of the measurement flow rate value in a diagnostic period which is defined in correspondence with a part of a period from a time point of closing the flow passage upstream of the flow rate sensor to a time point of expiration of a state that the measurement flow rate value and the target flow rate value are substantially nearly equal; and a diagnosing part configured to compare the inspection value and a predetermined specified value to diagnose whether an abnormality relating to the flow rate sensor is present. | 04-05-2012 |
20140083159 | SELF-CALIBRATING MECHANISM AND SELF-CALIBRATING METHOD FOR FLOW RATE SENSOR, AND DIAGNOSTIC MECHANISM AND DIAGNOSTIC METHOD FOR FLUID SENSOR - A valve fully closing part; a calibrating volume calculation part that calculates a calibrating volume on the basis value of an integration of a flow rate measured value outputted from a flow rate sensor in a fluid parameter changing interval; and a calibration part that calibrates a flow rate on the basis of the calculated calibrating volume and a preset reference volume are provided. | 03-27-2014 |
20150241264 | Self-Calibrating Mechanism and Self-Calibrating Method for Flow Rate Sensor, and Diagnostic Mechanism and Diagnostic Method for Fluid Sensor - A valve fully closing part; a calibrating volume calculation part that calculates a calibrating volume on the basis value of an integration of a flow rate measured value outputted from a flow rate sensor in a fluid parameter changing interval; and a calibration part that calibrates a flow rate on the basis of the calculated calibrating volume and a preset reference volume are provided. | 08-27-2015 |

20090067183 | Vehicular Room Illuminating Lamp - A vehicular room illuminating lamp includes: a plurality of illumination units applying voltages through courtesy wires thereof to lamps which irradiate positions in a vehicle cabin, the positions corresponding to four doors; a mode switch capable of selecting an all-lights-on mode, a door mode and a light-off mode; and a controller that individually receives a mode selection signal of the mode switch and respective door open/close signals of the four doors. The controller applies the voltages to all of the courtesy wires in the all-lights-on mode, applies the voltage only to the courtesy wire of the illumination unit corresponding to the door indicated to be open by the door open/close signal in the door mode, and doe not apply the voltage to any of the courtesy wires irrespective of states of the door open/close signals in the light-off mode. | 03-12-2009 |
20090073707 | Vehicle Interior Illumination Lamp Unit - A vehicle interior illumination lamp unit includes: a designed unit disposed on a lower side of a ceiling plate of a vehicle; and a functional unit disposed on an upper side of the ceiling plate of the vehicle and coupled to the designed unit. A spacer insertion space is provided on an outside of an operation plate of the functional unit, and an insertion plate portion of the spacer is inserted into the spacer insertion space, whereby engagement between an engagement hook and an engaged portion is inhibited from being released by an impact. | 03-19-2009 |
