Patent EP-0406027-A2 (EP)
Inventor: TSURUTANI KAZUSHI C O TONEN CO
IPC: F02D41/06
Filed: 1990-07-02
Abstract: Fuel supply in an ultrasonic atomizer is conducted according to a fuel increment ratio pattern in which the increment of fuel in fuel increment control for starting and warming up is 70% or less of that in a typical conventional pressure injection valve system, thereby improving startability, accelerability and fuel consumption rate and further enabling a reduction in exhaust emissions. 
     When the engine is started in low-temperature conditions, the fuel is supplied by continuous injection to make uniform and reduce the mean diameter of droplets of atomized fuel, thereby improving the ignitability and startability. 
     The fuel injection start timing is varied in accordance with the combustion chamber temperature at the time of starting the engine, i.e., when the engine is to be started in low-temperature conditions, no fuel is injected until a predetermined time has elapsed, and the fuel injection is started after the combustion chamber temperature has been raised by means of compression heat by driving the starter, thereby improving the cold startability even in the case of a fuel with a relatively high flash point. 
     When the engine is in a transient operating condition, fuel injection from the ultrasonic atomizer is executed immediately before the velocity of an air stream in the vicinity of the ultrasonic atomizer rises, whereby the fuel that is atomized with a sufficient spread in the intake pipe can be carried in this state by the air stream to the   combustion chamber where it is burned. 
     An ultrasonic atomizer comprises a vibrator horn (3) having at the distal end a slant portion and a reduced-­diameter portion of a smaller diameter than the slant portion, and a sleeve (4) disposed around the outer periphery of the vibrator horn to feed fuel over the entire circumference of the horn, the sleeve having an opening (4a) which faces the slant portion, whereby the fuel can be smoothly atomized by ultrasonic vibrations and sprayed with a predetermined spray angle.

Abstract: An electronic crash sensor which can operate appropriately in response to any form of crash of a vehicle. An input acceleration waveform (G) from an accelerometer (1) is first processed to peak cut any portion thereof lower than a predetermined value. Then, a value (G3) obtained from such peak cutting is time integrated. Then, a time integrated value (ΔV) of a predetermined function is subtracted from a value (V) obtained by such time integration. Then, the value of the acceleration waveform (V1) thus obtained is compared with a predetermined time function value (V2), and when the former is higher than the latter, a triggering signal is delivered to a trigger circuit (5) to trigger operation of a passenger protecting apparatus such as an air bag (6) of the vehicle.

Abstract: An apparatus and method for a power overvoltage protection system for limiting sudden transition line overvoltages. The apparatus and method include a voltage divider having a first varistor block and a second varistor block electrically connected in series. The first block and the second block each having a plurality of varistors. The first block exists in a nonconductive mode during normal operation of the power system. A thyristor circuit having a voltage sensor and a pair of oppositely coupled thyristors, is electrically connected between the first and second blocks and ground. The voltage sensor continuously senses line voltage V o , and a trigger mechanism continuously compares the sensed voltage V o  with a predetermined critical voltage of magnitude V p  to form a ratio. When the voltage V o  exceeds a predetermined threshold value of approximately 1.1 or 1.2 PU, the thyristor is activated into a conductive mode so that the line voltage V o  is entirely absorbed by the first block of the remaining voltage V o  through the oppositely coupled thyristor pair to ground. The thyristor is reset into non-conductive mode when the V o /V p  ratio falls below the predetermined value.

Abstract: An image-reading device, in which the 1-bit signals a CCD line sensor has generated from the light applied from an illumination lamp and reflected from an original (G) are shading-corrected, thereby forming image data. Before scanning the original, a black reference signal (V BK ), a white reference signal (V WT -V BK ) at a level higher than that of the black reference level, and three intermediate reference signals (V M1 , V M2 , V M3 ) are generated and stored into memories (44,45, 461, 462, 463). During the scanning of the original, a selector (49) selects two of the reference signals in accordance with the level of each signal output by the CCD line sensor, and the difference between the signal output by the sensor and the black reference signal (V BK ) is shading-corrected, by using the two reference signals selected by the selector (49). The signal output by the CCD line sensor can therefore made linearly proportional to the intensity of the input light, even if the CCD line sensor has no linear input-output characteristic or even if the photoelectric elements of the sensor have different input-output characteristics.

Abstract: Remote disconnecting devices are needed for being able to determine at the point of interconnection of the telephone network of one operator with the network of another operator in which part of the coupled networks a fault has occurred, that is to say to separate the networks from one another with respect to direct voltage for measuring purposes. 
<??>Remote disconnecting devices based on TRIACS and MOS-FETS are known, where a uniform switching threshold is used. If controlled silicon rectifiers are used as electronic switches, the switches are connected to one another by a switching element in order to be able to transmit dialling pulses from the telephone to the exchange and to use switches with insensitive control terminals. 
<??>According to the invention, the use of self-inhibiting MOS-FETs of the enrichment type provides for a high turn-on threshold and a low turn-off threshold so that the usual measuring method of dropping the voltage can be used. It is also possible to make the turn-on threshold dependent on the polarity of the voltage.

Abstract: A white noise suppressing circuit for suppressing white noise contained in a received voice of a loud-speaker telephone includes a filter (4) for suppressing white noise contained in an aural input signal input to an aural signal line (1), a switch (7) for short-circuiting the filter, a detecting circuit (8) for detecting the aural input signal, and a comparator (9) for comparing an output of the detecting circuit with a preset voltage and for controlling the switch on the basis of the results of the comparison. When it is determined by the comparator that there is a voice input, the switch is short-curcuited to make the filter inoperable. When there is no voice input, the switch is opened so as to make the filter operate. To improve the operation in the presence of high noise but low voice signal, specially connected charge and discharge time constant circuits (23a, 23b, 24a, 24b) of long and short time constants may be included between the detecting circuit and the comparator (Fig. 7).
