Title: Control device for fuel injection quantity of diesel engine
Inventor: SUGIYAMA TATSUMASA
IPC: F02D45/00
Filed: 1995-03-16
Abstract: PURPOSE: To carry out the highly accurate control of an injection quantity by correcting target spill valve opening time based on a deviation between actual spill valve closing time and target spill valve closing time, and thereby absorbing an error caused at the time of the closing control of an electromagnetic spill valve at the time of its opening control to reduce an error in the infection quantity. CONSTITUTION: A fuel injection pump 1 is driven by the crankshaft 40 of a Diesel engine 2 through a driving pulley 3 to pressure-feed fuel to a fuel injection nozzle 4. An electromagnetic spill valve 23 for regulating a fuel spill from a pressurized chamber 15 is provided in a spill passage 22 formed in a pump housing 13. In addition, the crankshaft 40 is provided with a crank angle sensor 76 for detecting its rotating position. In this case, a prestroke control is carried out for controlling together the opening and closing time of the electromagnetic spill valve 23 on the number of counts from the generating time of a reference rotation angle signal to the opening and closing time of the target spill valve and residual angle time 1. Thus the target spill valve opening time is computed on a deviation between actual spill valve closing time and the target spill valve closing time.

Title: Automatic setting device of exposure time
Inventor: MIZOGAMI KAZUNORI
IPC: G03B9/62
Filed: 1978-05-18
Abstract: PURPOSE: To set always optimum exposure time on film faces of different reflectances by correcting the rear curtain travel start point by the use of the differential signal between the reflected light from the front curtain immediate after the start of travel and the reflected light from the film plane after passing of the front curtain.  
     CONSTITUTION: Photo cells 11a, 11b are connected to a rear curtain driving control circuit 21 and a photo cell 12 is connected to a correcting circuit 22. Thereupon,  when a release lever is pushed, the front curtain starts traveling and the reflected  light from the front curtain enters the photo celles 11a, 11b, 12. Then the voltage  acrross a capacitor 31 rises in correspondence to the outputs of the photo cells 11a,  11b. When the front curtain becomes fully open, the signal V 2  is outputted in correspondence to the difference between the reflected light from the front curtain and the reflected light from the film plane from a differential amplifier 48. This signal is then introduced into an arithmetic circuit 27. Hence, the voltage having corrected the constant voltage V 1  by V 2  is introduced as a reference voltage to one of the input ends of a comparator 28 and when the voltage across the capacitor 31 exceeds the output voltage of the arithmetic circuit 27, the rear curtain starts traveling.

Abstract: PURPOSE:To prevent the surface crack due to ununiform cooling by measuring a temp variation of cast slab corner part with arranging an infrared sensor at secondary cooling zone and controlling a cooling speed based on the temp. CONSTITUTION:In the continuous casting of a high carbon steel containing >=0.70% C, an infrared sensor is arranged facing to a cast slab corner part at the prescribed interval in cooling zone, measuring a temp variation of the cast slab corner part at casting.

Filed: 1989-03-14
Abstract: PURPOSE:To prevent the degradation in sound hearing at the time of the occurrence of code error in the middle of transmission by comparing a decoded signal with a step width with one bit as the unit and attenuating the output signal. CONSTITUTION:An encoder 20 and a decoder 21 are provided with comparing attenuators 7 and 13 respectively.

The absolute value of the amplitude of the signal delayed by one bit and the amplitude of a signal obtained by multiplying the step width output by (k) (k=2 to 4) are compared with each other with one bit as the unit, and the amplitude of the forecast signal is multiplied by P (0.8<P<0.99) when the former exceeds the latter. Thus, the degradation on sound hearing is prevented at the time of the occurrence of code error in the middle of transmission.
