Filed: 2015-09-07
Abstract: PROBLEM TO BE SOLVED: To determine abnormality with a simple configuration according to the state of a controller such as an ECU for controlling supply power to a load whether it is in a power saving state or a normal state.SOLUTION: When determining a shift abnormality of ECUs 5a-5e to a slave state, current supply switches 19a-19d are successively switched on while a bypass switch 13 is kept on. Depending on whether or not a dark current in the ECUs 5a-5e, which is determined from a variation of a current Isens of a power supply path 7 at this time, is larger than the magnitude of a normal dark current, a supervision controller 21 determines an abnormality of shift of the ECUs 5a-5e to the sleep state. Further, in the activated state of the ECUs 5a-5e, the power of a power supply VB is supplied to the ECUs 5a-5e through a power supply path 7 and individual supply paths 9a-9d.SELECTED DRAWING: Figure 1

Filed: 2015-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a new electric fluid pump that is able to prevent a change in an installation angle of a connecting-wire guide even when the connecting wire is wound around the connecting-wire guide.SOLUTION: The outer peripheral surface (OS) of a stator in a radial direction thereof and an insulating flat part (20C) orthogonal of the outer peripheral surface of the stator of an insulating base part (20UB) with a connecting-wire guide (42) formed thereon are covered with a synthetic resin (51) of predetermined thickness. According to this, since the insulating flat part of the insulating base part with the connecting-wire guide formed thereon and the outer peripheral surface of the stator are coated by the synthetic resin, a change in installation angle of a connecting- wire guide is restricted by the synthetic resin present on the outer periphery of the stator even if winding force acts towards the inside of the stator when the connecting wire is wound around the connecting-wire guide. Accordingly, loosening of the connecting wire is prevented.SELECTED DRAWING: Figure 6
