Title: Method and device for improving resolution and contrast of optical printer
Inventor: DAGURASU ENU KAARII
IPC: G02B26/12
Filed: 1993-06-25
Abstract: PURPOSE: To improve the contrast by a printer by subjecting a writing device to brightness modulation to form the composite exposure profile crossing a zerographic threshold in a process direction by the transition of an image. CONSTITUTION: The amplitude, duty cycle and/or pulse width of laser beam 13 are serially modulated (brightness modulation) on the basis of successive multibit digital data values. These data values respond to data clock pulses to be serially subjected to timing output from a buffer data source 23 and the data clock pulses are made synchronous to the scanning of a scanning spot from the bit map position in a raster scanning pattern to a bit map position with time. Therefore, data lock frequency can be selected so as to map data into the raster scanning pattern in desired magnification by using magnification same or different in a high speed scanning direction and a process direction.

Abstract: PURPOSE:To make it possible to omit tridimensional map with excellent controllability being maintained, when the air-fuel ratio is learned and corrected based on the detected value of an O2 sensor, by computing correcting quantity in correspondence with the computed value of two or more control variable. CONSTITUTION:When a timer routine 300, which is processed every 10sec, is started, a correcting quantity DELTAK1 is added to or subtracted from an air-fuel ratio returning control quantity K1 from the O2 sensor in steps 301-306, based on the output of the O2 sensor. The result is stored in an RAM in a step 306. When the operating state, at which the learning conditions are satisfied, is judged in a step 307, the values of K1 are accumulated in a step 312 until a counter C0 counts 500. when this value is exceeded, an air intake quantity KQ is computed by an expression (constant KA X engine speed Ne X intake air pressure Pe) in a step 311. When an average Km of an accumulated values Ks of K1 exceeds 1.02 or becomes smaller than 0.98, a learning correction term Kn corresponding to KQ is computed in steps 317 and 318.

Abstract: PURPOSE:To improve collecting efficiency of soot, reduce clogging and provide the ventilating fan provided with the filter prominent in cleaning property by a method wherein the filter is made by a metallic wavy plate having multitude of small openings while the filter is constituted so that the direction of the troughs of wavy plate is vertical. CONSTITUTION:The filter 15 is made by a corrugated punching metal 16, therefore, the effective area thereof is large while the rate of perforation is large, therefore, the pressure loss thereof is small. The size of the holes is small, therefore, large particles of oil can be arrested surely while the direction of flow of air becomes diagonal with respect to the holes, therefore, the possibility of collision of oil particles against the filter 15 becomes large and high collecting efficiency may be obtained. The arrested oil is pushed by airflow and is collected into the troughs of the filter 15, then, flows down along the lower part of the troughs and is collected into an oil receiving pan; therefore, clogging of the openings is small as compared with the case of a flat filter. On the other hand, if the height between the crest and trough of the corrugation of the filter 15 is not so large, the filter may be cleaned easily by washing along the direction of the troughs with a brush.
