Title: Fuel injection amount control device for diesel engine
Inventor: IKEDA SHINJI
IPC: F02D41/40
Filed: 1993-11-08
Abstract: PURPOSE:To prevent dispersion caused by detection error of engine rotation so as to improve control accuracy by correcting a real value according to a difference between the real value and a demand value in relation to the spill angle of a spill valve when the injection amount of fuel fed under pressure by a pump is controlled by the spill valve. CONSTITUTION:Fuel is fed under pressure from a fuel injection pump A3 driven by diesel engine A1 while controlling an injection amount by a spill valve A2. At this time, the demand spill angle of the spill valve A2 is calculated by a demand spill angle calculating means A4. An engine rotational pulse is outputted from an engine rotation detecting means A5 per the constant crank angle of an engine. A count number from the reference position of the engine rotation pulse to a spill position and an angle which is less than 1 pulse are calculated by an angle time calculating means A6, and a remaining angle is reduced to a time. The spill valve A2 is controlled by a spill valve control means A7 on the basis of the count number and the remaining angle time. In this case, a real spill angle is corrected by a spill angle correcting means A8 according to the difference between the rear spill angle and the demand spill angle.

Abstract: PROBLEM TO BE SOLVED: To provide a means for efficiently producing a desired fluoride, especially a perfluoro compound in high yield by fluorinating a partially fluorinated organic compound and to provide a reactional apparatus therefor. SOLUTION: A fluorine-containing gas is fed from the bottom of a reactional apparatus having a structure in which a tank-shaped reactional zone is connected to the top of a columnar reactional zone so that gas and liquid flow can be carried out and the internal pressure of the tank-shaped reactional zone is weighted to the internal pressure of the columnar reactional zone and the ratio (V2/V1) of the internal volume (V2) of the tank-shaped reactional zone to the internal volume (V1) of the columnar reactional zone has a relationship of 0.2-2. A liquid organic compound having carbon-hydrogen bonds is fed to the tank-shaped reactional zone at the top and the liquid is kept in a uniformly mixed state in the tank-shaped reactional zone.  The liquid flowing down to the columnar reactional zone flows down as a piston flow in the column while being brought into contact with the fluorine-containing gas and then discharged from the bottom of the columnar reactional zone.

Title: Kerosene burner
Inventor: NAKATANI KAZUTO
IPC: F23N5/00
Filed: 1986-11-25
Abstract: PURPOSE:To detect an oxygen deficiency state in a stable oxygen concentration without influence from the amount of combustion by installing a compensating part which changes the detected level of a detecting circuit in response to the amount of combustion at a combustion part in the detecting circuit sensoring the change in the output of a detecting element. CONSTITUTION:A variable resistor 5 of which resisting value is varied in connection with an adjusting part 4 for the amount of combustion functions as an adjusting part for the detected level of oxygen deficiency. when the output by an NTC thermistor 13 is lower than a reference voltage, a buzzer 22 is operated to induce ventilation. When an oxygen deficiency state occurs in the maximum combustion condition, though the resistance of the thermistor 13 is rather higher, the resistance of the resistor 5 which determines the reference voltage used for comparison with the output of the thermistor 13 at a comparator 21 becomes also high. Conversely, when the oxygen deficiency state occurs in the minimum combustion condition, though the resistance of the thermistor 13 is rather lower, the resistance of the resistor 5 is also low, and therefore the detected level of oxygen deficiency at that condition is almost the same as that in the maximum combustion condition. Therefore, in either case, the buzzer 22 is operated in almost the same oxygen concentration.

IPC: G06K7/10
Filed: 1985-12-13
Abstract: PURPOSE:To reduce the size of a device by making projection laser light from a scanning laser light generation part incident on a scan expanding element. CONSTITUTION:The laser light C incident on the curved surface 52 of the scan expanding element is refracted by the curved surface 52 to a direction more than the critical angle at which it is reflected totally in a transparent plate 51 and guided out of a slanting surface 53. The scanning angle alpha1 when the laser light C is incident on the curved surface 52 is increased to a scanning angle alpha2 because of the incidence on the curved surface 52, and further increased to a scanning angle alpha3 when the light is guided out of the slanting surface 53. The scanning angle alpha3 is much larger than the scanning angle alpha1, so the beam length is shortened without any decrease in the number of scanning lines and the device is reduced in size.
