摘要:
The present invention provides a diagnostic apparatus for an evaporative emission control system which can accurately execute leak diagnosis under a stable condition. An ECU clocks a time td2 until the internal pressure value Pte of the evaporative emission control system sealed at the negative pressure reaches the target internal pressure value Pd, sets the pressure change measuring time te2 based on the clocking time td2, and measures the pressure change amount P1 which varies after the internal pressure value Pte of the evaporative emission control system reaches the target internal pressure value Pd for a pressure change measuring time te2. Then, the ECU sets the determination value Pth0 based at least on the spatial capacity of the evaporative emission control system, and determines whether the evaporative emission control system is normal or abnormal based on the pressure change amount P1.

摘要:
In a diagnostic apparatus for an evaporative emission control system having a fuel tank is hermetically sealed under negative pressure on the basis of target inner pressure, and leak of the evaporative emission control system is judged when a diagnosis value based on a pressure variation amount after the hermetical sealing under at least negative pressure is larger than a judgment value, ECU estimates an evaporated fuel generated amount on the basis of a tank inner pressure value at the start time of a diagnosis. When the evaporated fuel generated amount thus estimated is large, target inner pressure Pteb is set to a high value, and when the evaporated fuel generated amount thus estimated is small, the target inner pressure Pteb is set to a low value.

An inner fin is an offset fin having a wavy cross-section that is perpendicular to an oil flowing direction, and has a louver that is partially cut and bent in a direction parallel with the oil flowing direction. The wavy cross-section is defined by alternately placing first-side convex parts and second-side convex parts. A fin height fh is defined by a distance from the first-side convex part to the second-side convex part in the cross-section. An area surrounded by the inner fin, a tube, and the first-side or second-side convex parts located adjacent with each other on the same side in the cross-section is converted into a corresponding circle having a diameter de. When a relationship of X=de/fh0.3 is defined, the diameter of the corresponding circle and the fin height respectively have dimensions that satisfy a relationship of 0.5≦X≦1.0.

In a RAM 1-3, a data area and a current memory are provided. A signal processing portion 1-10 processes audio signals in accordance with a parameter set stored in the current memory. In the data area, a plurality of S data sets each formed of a parameter set and an S list which is a list of S data sets are stored. Each S data set is identified by its unique identification information (SID). The S list stores list information including SIDs which identify the respective S data sets. When storage of the parameter set stored in the current memory is desired, a new SID is generated, so that list information including the generated SID is added to the S list, with the SID being added to the parameter set of the current memory to be stored as a new S data set in the data area.

When a controlled device has changed the value of a parameter, the controlled device transmits the result of the change as updated information UPDATE to controllers by multicast, and aside from this, also transmits synchronization data SYNC in each synchronization period by multicast. Upon detecting a reception error of those data, the controller requests, from the controlled device, the information of the parameter which has been changed in one or more synchronization periods including and after the synchronization period subsequent to the last synchronization period in which the controller could normally receive all of the packets, and corrects the parameter value in the controller based on the current value of the changed parameter transmitted from the controlled device in response to the request.
摘要:
The present invention relates to a method of adjusting a flow rate sensor 52 for measuring a travel time of a sample passing through a resistive body. The flow rate sensor 52 includes a straight tube 56, and plural photo sensors 52A to 52E for detecting interfaces 82A, 82B between a gas 80 and a liquid 81 traveling in the straight tube 56. Respective positions of the plural photo sensors 52A to 52E are adjusted by detecting the interfaces 82A, 82B by using such photo sensors 52A to 52E.

An organic EL display formed by welding a lid body and a substrate is arranged in a recessed surface of a cabinet; and at least two cushions are arranged between a bottom surface of the recessed surface and the substrate, the cushions being spaced apart from each other along a longitudinal direction of the cabinet. A friction reducing layer, which friction with the substrate of the organic EL display is small, is formed on the cushion, and the substrate is slidable on the cushion.
