摘要： An abnormality detector for motor drive system easily detects, using a CPU, abnormality such as short circuit or disconnection in magnetic field coils of a motor, wiring, an open/close element, etc., which are controlled by a microprocessor (CPU). The open/close elements conducting an open/close operation sequentially in response to pulse outputs P1, P2 generated by the CPU, drive the magnetic field coils. Surge voltages generated upon interrupting the mentioned open/close elements are OR connected through a diode, and input to a temporary storage circuit. Then the CPU reads out, stores and resets the surge voltages using pulse edges of the pulse output P1 or P2. When any generation of the surge voltage is not stored in the temporary storage circuit, the CPU operates an abnormality alarm display.

摘要： An omnidirectional camera device is able to restrict a range in which images of objects are picked up. This omnidirectional camera device comprises a rotationally-symmetric convex mirror (24) fixedly attached to one end of a transparent tube assembly (20), an image pickup means (32) disposed on the other end of the tube assembly in an opposing relation to this convex mirror and a cover assembly (60) disposed on the tube assembly for restricting the range in which light becomes incident on the convex mirror. The cover assembly is mounted on one end side of the tube assembly. The cover assembly is a shielding cover assembly and includes a cover member (60B). The cover assembly is attached to the tube assembly so as to become freely rotatable. The direction and the range in which images of objects should be picked up may be adjusted by the attachment position of the cover assembly and a shielding angle &agr; of the cover assembly. Thus, since undesired video information may be eliminated, only pictures of objects in the desired ranges may be picked up, which becomes effective in analyzing information.

摘要： An O.sub.2 -sensor fault diagnosis method and apparatus for detecting a fault of an O.sub.2 -sensor when a feedback control of a fuel supply to an engine is performed by making use of the output of an O.sub.2 -sensor and detecting and identifying a fault of the O.sub.2 -sensor even in the case where the feedback control is invalidated. A microcomputer (24) receives an output of an O.sub.2 -sensor (19) for detecting concentration of oxygen contained in an exhaust gas of an internal combustion engine (1). An ECU (20) controls a quantity of fuel supplied to the internal combustion engine (1) through feedback control in dependence on an output signal of the O.sub.2 -sensor (19). A first decision circuit is provided for deciding whether or not the O.sub.2 -sensor (19) exhibits abnormality on the basis of the output signal state of the O.sub.2 -sensor (19) by forcibly changing the amount of the fuel supplied to the engine during the feedback control, and a second decision circuit is provided for deciding abnormality of the O.sub.2 -sensor (19) in accordance with an abnormality decision process which bears a stronger correlation to the abnormality than the decision performed by the first decision circuit. Fault detection of the O.sub.2 -sensor is possible not only during the feedback control of the fuel supply but also in the state where the feedback control is not performed.
