Abstract: PURPOSE:To adapt a device to a quick variance of voltage to suppress the variance of voltage, by connecting a ripple eliminating circuit consisting of a square-law detector, a delay element, and an adder to a bus voltage input and eliminating the ripple to perform the feedback control smoothly. CONSTITUTION:The output of a square-law detector 73 due to a bus voltage input (v) consists of a DC component and a component having the double frequency of a power source frequency if the waveform distortion does not exist in the bus voltage. If a delay element 74 has a function to delay an electric power source period T by 1/4, an output shown in a Fig. (a) is attained, and outputs of the detector 73 and the element 74 are added in an adder 75 to attain an output V having a waveform shown in a Fig. (b). This output V is the sum of the output of the detector 73 and its T/4-delayed output and is equivalent to the output attained by delaying the output of the square-law detector by only T/8, and an adaptive voltage value where the ripple is eliminated sufficiently is attained. This detected voltage value is inputted to suppress the variance of voltage adaptively to the quick variance of voltage.

Abstract: PURPOSE:To make a constant current flow in a hazard switch at all times as well as to prevent this switch from being damaged due to heat generation, by setting up a relay, operating with the said switch turned on, between this hazard switch and symmetrical flashing bulbs. CONSTITUTION:When a hazard switch 17 is turned on, each of relay coils 21 and 31 is excited, and each of relay contacts 22 and 34 is closed, while the relay contact 34 is connected to a normally opened contact 32. Therefore, a current out of a battery 1 flows into a fuse 4, the relay contact 34, a flasher unit 8, relay contacts 22 and 23, and each of flashing bulbs 5 and 6. At this time, the current flowing in the hazard switch 17 is only such one flowing into each of these relay coils 21 and 31, so that if load resistance is increased, such a problem that the hazard switch 17 is heated so much and thereby damaged will not happen at all. On the other hand, when the hazard switch 17 is turned off, each of these relay contacts 22 and 23 comes into a state of being opened, and the relay contact 34 is connected to a normally closed contact 33.

Filed: 1988-02-02
Abstract: PURPOSE:To aim at smoothly starting a vehicle by releasing a clutch when an engine is overloaded so as to prevent the engine from stopping during rapid starting or the like, and by starting the clutch feed at a lower speed when the overload of the engine is eliminated. CONSTITUTION:A discriminating section 49 discriminates whether an engine overload phenomenon in which the rotational speed of the engine decrees below a rotational speed which copes with the operating condition of the engine occurs or not, during the turn-on side feed of a clutch. A first computing means 41 computes a first clutch feed speed corresponding to the operating condition. A control section 60 stops the clutch feed when an engine overload discriminating signal is issued. Further, a second computing section 42 computes a second clutch feed speed which increases from a low initial feed speed with the lapse of time. Further, in association with the presence of the engine overload discriminating signal, a selecting section 40 selects the first and second clutch feed speeds.
