Title: Failure detector for exhaust gas recirculation apparatus
Inventor: KAWAI TAKASHI
IPC: F02D41/22
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To provide a failure detector for an exhaust gas recirculation apparatus capable of suppressing deterioration in drivability at the time of detecting the failure of the exhaust gas recirculation apparatus. SOLUTION: At the time of detecting some failure of an EGR mechanism, a target EGR opening Et of an EGR valve 43 is changed from a normal value to a failure detecting value, and the EGR valve 43 is closed till the target EGR opening Et for failure detection. When the EGR valve 43 is closed as described above under a condition that the ERG mechanism is normal, the target EGR opening Et for failure detection is calculated based on an engine operation condition so that the amount of decrease ΔP of intake pressure PM of an engine 11 may become constant.  As a result, when the EGR valve 43 is closed as described above, the amount of a drop ΔT in the output torque of the engine 11 changing with the amount of a drop ΔP in intake pressure PM becomes almost constant, thereby restraining the amount of the drop ΔT in the output torque from increasing extremely only at the time of a prescribed engine running condition.

Abstract: PURPOSE:To adjust the positional relation of plural movable reflection mirrors with simple constitution by allowing the movable reflection mirror driven at constant speed and the movable reflection mirror driven at half speed thereof to abut on each other, thereby positioning them. CONSTITUTION:Wires 29 and 30 for transmitting driving force to the movable reflection mirrors 6 and 7 are fixed on the reflection mirror 6 by fixing plates 31 and 32 through half-speed pulleys 27 and 28 provided at both ends of the mirror 7. When the wires 29 and 30 are driven, the mirrors 6 and 7 are moved on a pair of optical rails 33 and 34 in the speed ratio of 2:1. Abutting members 35 and 36 are provided on the pair of optical rails 33 and 34 so as to abut on the abutting surfaces 37 and 38 of the mirror 7. By allowing the abutting surfaces 39 to 42 of both mirrors 6 and 7 to abut, both mirrors 6 and 7 become in parallel with each other. Therefore, when the positional relation between the mirrors 6 and 7 is changed because of the looseness of the wires 29 and 30, it is easily adjusted to the specified positional relation by stretching and laying the wires 29 and 30 again in a state where both mirrors 6 and 7 are allowed to abut.

Title: Surface acoustic wave element and its producing method
Inventor: ONISHI KEIJI
IPC: H03H9/02
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain an element that has a satisfactory temperature characteristic by making the coefficient of thermal expansion of an auxiliary substrate smaller than the coefficient of thermal expansion of a main substrate and making the auxiliary substrate thicker than the main substrate. SOLUTION: When a main substrate 101 and an auxiliary substrate 102 are overlapped through water and water is gradually eliminated, they change to conjunction through intermolecular force such as hydroxyl group, oxygen and hydrogen and both are strongly conjugated. A comb-shaped electrode 103 is formed on a main substrate side surface of an acquired conjugate. The substrate 101 whose coefficient of thermal expansion is large and the substrate 102 which is thicker than the main substrate and whose coefficient of thermal expansion is small are directly conjugated, compressive stress works near the surface of the main substrate due to positive temperature change to show a value that is smaller than the normal coefficient of thermal expansion of the substrate 101 and density change also becomes small. Therefore, the change of temperature dependency becomes small, the coefficient of linear expansion in the direction of surface acoustic wave propagation becomes small, and also, the frequency temperature characteristic of a surface acoustic wave element is improved.
