Patent EP-0357426-A3 (EP)
Title: Light quantity controlling apparatus
IPC: H01L33/00
Filed: 1989-08-31
Abstract: A position detecting apparatus (Fig. 1) usable for 
aligning a mask (15) and a semiconductor wafer (16), 
wherein a laser beam (14) produced by a semiconductor 
laser (1) is projected through a predetermined optical 
system to alignment marks (15a,16a) formed on the mask 
(15) and the wafer (16), and the light (17) reflected 
by the marks is detected by an accumulation type 
sensor (4) to produce an electric signal, from which 
the relative positional relation between the mask (15) 
and the wafer (16) is detected on the basis of the 
electric signal. To obtain proper mark signals, the 
quantity of light incident on the accumulation sensor 
(4) is controlled. In this apparatus, the beam 
emitting strength of the semiconductor laser (1) is 
made constant, and the control of the amount of light 
incident on the accumulation sensor (4) is effected by 
controlling (2) the operation period of the 
semiconductor laser (1). In addition, the actuation 
timing (7) of the semiconductor laser (1) is advanced 
from the accumulation start of the accumulation type 
sensor (4) by the time (Ts) required for the 
semiconductor laser (1) to be thermally stabilized 
after its actuation. The mark detection signal 
produced by the accumulation sensor (4) is precise.

Abstract: A method for detecting misfire by fluctuation in
crankshaft rotation in which the occurrence of misfire
can be detected exactly by eliminating the effect of
detection error in detecting the fluctuation in
crankshaft rotation, caused by the error in the
construction of a crank angle sensor. By succeedingly
receiving pulses from the crank angle sensor, a
processor detects a time interval taken from the
entering into a crankshaft rotation angle region,
relating to a cylinder corresponding to both pulses,
to the leaving therefrom (S2), calculates the
crankshaft angular acceleration Dω n  by using the
correction factor calculated on the basis of the above
detected time interval, and the time interval
determined by dividing the time taken for one rotation
of crankshaft by the number of cylinders (S3, S4), the
latter interval being free from sensor error, and
detects the occurrence of misfire when the calculated
value Dω n  is less than the decision value (S5 through
S7).
