摘要： A device for indicating disconnection of automotive lamps comprising a current winding energized by a load current of a lamp and a voltage winding phase-inverted from said current winding for generating a small magnetomotive force, said two windings combining to operate the contact of an indicator circuit, whereby disconnection of one of four or more parallelconnected lamps is successfully detected and indicated under widely varying conditions of a source voltage, thus overcoming the limit of detection which is posed by the load characteristic of the lamps.

摘要： There is provided a fault detecting and indicating system for a vehicle whereby when the level of engine oil or the thickness of brake lining becomes smaller than a predetermined value, such an abnormal condition is detected by a fault detector and an indicator lamp is lighted by a detection holding circuit. The indicator lamp is designed so that it is not allowed to go on in response to any transient fluctuations in the level of the engine oil, whereas once the indicator lamp has been lighted it is held on until a power switch is opened and it is thus independently of the fault detector. The fault detecting and indicating system is further provided with a check circuit which is capable of separately checking the indicator lamp for burnout.

摘要： A device for indicating the disconnection of lighting means in an automobile which insures accurate indication in spite of normal lighting load current variations caused by filament temperature changes, operation sequences, etc. The device includes at least one indicator connected to a power source through a normally closed relay contact that is held open by the normal light load current when there are no disconnected or nonfunctioning lights. The relay coil includes a current coil for carrying the load current and a voltage coil connected in series with a capacitor to cumulatively add to the magnetomotive force of the current coil during an initial period when the light circuit is first switched on to thereby insure an initial opening of the normally closed relay contacts even if some of the light load is disconnected or nonfunctional. In this manner, the normal current variations during the initial period of operation do not cause an erroneous malfunction indication but, rather the current in the current coil after the initial time period is effective to cause accurate malfunction indications.

摘要： 1462922 Indicating faults NIPPONDENSO CO Ltd and TOYOTA JIDOSHA KOGYO KK 23 May 1974 [2 June 1973] 23100/74 Heading G1U [Also in Division F2] A fault indicator includes a differential relay including two oppositely wound coils, one of which becomes de-energized on the occurrence of a fault, causing the field of the other coil to actuate a magnetic switch which operates an indicator and also short circuits the de-energized coil. Switch 9 is normally closed, thus coils 3, 4 are both energized and their fields cancel out leaving reed switch 5 open. On switch 9 opening, coil 3 is de-energized, and the field of coil 4 closes the switch 5 allowing current to flow through indicator lamp 8. A path is also closed through resistor 1, diode 7 and switch 5 which short-circuits the coil 3 such that if switch 9 now closes, e.g. through vibration, coil 3 remains de-energized. The bulb 8 is tested by connecting switch 14 to the positive supply, whereon transistor 12 conducts and the bulb should light. Other embodiments involve a delay between the occurrence of a fault and the opening of switch 9 to obviate response to spurious events Figs. 2, 3 (not shown) and modifications to utilize a normally open switch 9 Fig. 3 (not shown). The device may be used to indicate the low level of oil in a pan or a vehicle in which case preferably two reed-switches 9 are used in parallel and mounted at right-front and left-rear, these being operated by magnetic floats. Another embodiment is used to detect the wear of a brake pad lining Figs. 4, 5 (not shown). The test circuit is similar to the Fig. 1 embodiment except that switch 9 is omitted, the bottom end of the coil 3 being grounded and a wire embedded in the brake pad forms the connection between resistor 1 and coil 3. Thus if this point is grounded, coil 3 is de-energized and the circuit operates as before.

摘要： An improved liquid level detecting and indicating system for vehicles comprising a pair of liquid level detecting elements which are arranged in opposite positions on the detecting level of a liquid in a liquid container installed in a vehicle, whereby when each of the liquid level detecting elements sends a signal indicating that the liquid level has dropped below a reference liquid level, an indicator is brought into operation. In this way, the level of liquid can be accurately detected and indicated without being influenced by the inclination or vibration of a vehicle body.
