Abstract: PURPOSE:To obtain a true intake air volume and enhance control accuracy by performing the inverse operation of the intake air volume from the result of the correction of a fuel supply amount based on a detected value, regardless of any difference in the intake air volume based on the detected value of an engine operation parameter. CONSTITUTION:A fuel supply control device A detects an air volume parameter with an air volume parameter detection means B, and a fuel supply amount is operated with a fuel supply amount operation means C, based upon the result of the detection. Also, the air-fuel ratio of a mixture is detected with an air-fuel ratio detection means D, and the fuel supply amount is so corrected with an air-fuel ratio control means E as to bring the result of the detection near a target air-fuel ratio. Furthermore, the fuel supply amount is controlled with a fuel supply control means F, depending upon the corrected fuel amount. In the aforesaid construction, an intake air volume is inversely operated with an intake air volume reverse operation means G. Also, line pressure is set up with a line pressure setting means H, on the basis of the inversely operated intake air volume. Furthermore, a line pressure control signal corresponding to the set line pressure is outputted to the hydraulic circuit K of an automatic transmission J by a control signal output means I.

Patent JP-S63185657-A (JP)
Title: Thermal printer
Inventor: MINOWA MASAHIRO
IPC: B41J2/36
Filed: 1987-01-29
Abstract: PURPOSE:To prevent the deterioration of printing quality due to heat accumulation in a thermal head, by storing the driving hystory of a heat generating element by an amount of printing data for at most one basic character, and reducing energization energy for the heat generating element by eliminating a part of a basic energization time according to the data stored. CONSTITUTION:For correction of a temperature rise in a thermal head, the duration of energizing pulses is varied according to the driving history of heat generating elements previously driven. For the correction, it is sufficient to store an amount of data for at most one basic character. For example, when a basic character is constituted of a dot matrix of (n) dots (vertical) X (m) dots (horizontal), it is sufficient to store an m-dot-column amount of data. When a trigger input Tg is applied to an input terminal IN, charging of a capacitor 31 is started through a resistance circuit comprising a thermistor 34, and when a predetermined charged level is reached, a pulse with a duration TW suitable for the temperature of the thermal head at that moment is outputted from an output terminal OUT of a comparing circuit 37. The output is used directly as a basic energization time for the thermal head, so that it is made possible to supply appropriate printing energy to the heat generating elements 3 by turning ON and OFF a power source terminal for a driver.

Title: Ultrasonic transmission and reception array
Inventor: KAMATA HIROSHI
IPC: H04R1/40
Filed: 1980-02-20
Abstract: PURPOSE:To reduce the dispersion of the sensitivity of oscillator and to enable transmission and reception of ultrasonic wave information in a medium without distortion, by using the rubber cork plate as buffle and taking the radius of ultrasonic wave oscillator as about 1/10 or less than the wave length of ultrasonic waves. CONSTITUTION:The sound pressure exerted to an ultrasonic wave oscillator (array element) 1 is double since the oscillator 1 is almost a complete rigid body. The sound body exerted to the oscillator 1 is in acoustic-electric conversion, and amplified at the associated electronic circuit 5 and transmitted on land with a transmission cable 6. When the rubber cork plate is used as buffle, since the rubber cork plate 2 shows the effect cancelling the sound pressure to the direction of + or -90 deg., i.e., the sound waves from parallel direction as the arranging plane of the array, the directivity of the array element 1 is a directivity smaller in the sensitivity toward + or -90 deg., i.e., unidirectivity. Since the radius of the array element 1 is less than about 1/10 of the wave length of the ultrasonic waves, the directivity is undirectional to reduce the dispersion in the sensitivity of the array elements 1.

Filed: 1987-01-31
Abstract: PURPOSE:To properly correct a roll opening and to accurately perform a plate rolling by accumulating variations of the roll opening momentarily and giving the mill rigidity of a rolling mill as a previously provided function of the accumulated value. CONSTITUTION:A rolling load P(t), the roll opening S(t) at the time (t) are detected by detectors 2, 3, then P(t) and S(t) are stored. The variation  S(t) of the roll opening is calculated and stored. The direction of varying the roll opening at the present time is discriminated whether it is equal to the roll opening varying direction at a time before or not. If the roll opening direction is equal, the roll opening variation  S(t) is accumulated on the roll opening accumulated value from the past. If the direction of the roll opening is reverse, the roll opening accumulated value is reset. According to the roll opening accumulated value, the rigidity M of the rolling mill is calculated. A tuning coefficient is made as K, and a control gain is multiplied and impressed on a rolling reduction apparatus. By repeating this steps, the roll opening is corrected momentarily, the high accurate plate thickness control is performed.
