Title: Resolver disconnection detecting method
Inventor: KUSHIHARA HIROSHI
IPC: G01R31/06
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To realize a method capable of detecting a disconnection regardless of the rotational angle by applying a DC bias current to an output winding and outputting a disconnection detection signal having a voltage level higher than the maximum voltage level of a rotational angle signal from a differential amplifier when the output winding is disconnected. SOLUTION: When an output winding 3 is not disconnected but normal, a rotational angle signal sinθ.f(t) or cosθ.f(t) is outputted from an output terminal 8c through a differential amplifier 10. When the output winding 3 is disconnected, a DC bias current IB does not flow into the output winding 3 and a sixth resistor RBL. At the same time, a DC power supply 11 is applied to the differential amplifier 10 through buffer circuits 6, 7 and a disconnection detection signal 20 is outputted in place of the rotational angle signal. The disconnection detection signal 20 has a voltage value higher than that of the rotational angle signal sinθ.f(t) or cosθ.f(t) and disconnection can be detected by monitoring the voltage level thereof by means of a window comparator, or the like.

Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a verification method, for the function of a catalyst, in which whether the function of the catalyst used to remove NOX (nitrogen oxides) is sufficient or not is verified by using a gas sensor which can measure the concentration of the NOX. SOLUTION: First, in order to restore the function of a catalyst, an air-fuel ratio is controlled so as to be shifted to the rich (R) side. After that, the air-fuel ratio is controlled to the lean side. Then, the air-fuel ratio is controlled to the lean side, and the concentration of NOX is measured. When the concentration of NOX is sufficiently low in the same manner as a concentration in the operation of an ordinary engine 2, it is regared that the function of the catalyst is restored. The concentration of NOX is higher than the concentration in the operation of the ordinary engine 2 even when a rich spike is hit so as to execute a treatment to restore the function of the catalyst. Then, it is regarded that the function of the catalyst is not restored.

Since the film 2 itself is composed of a material extensible and contractible to the plane direction of the film 2, it has a sufficiently cushioning function to the plane direction. The lead electrode of a mount board is brought in continuity to the electrode of the element 1 by a conductive layer for coupling a through hole 5 in the piece 4 to be opposed to the lead electrode of the element 1 to a through hole 5 opposed to the lead electrode of the mount board.
