Title: Image processor and processing method
Inventor: WAKANA TORU
IPC: B41J5/30
Filed: 1996-11-18
Abstract: PROBLEM TO BE SOLVED: To store a large volume of data in a memory resource having a specified size while reducing the memory by degrading a raster data when a compressed raster data can not be stored in a specified raster memory. SOLUTION: Control section of a printer delivers an image data, generated from an external unit and described with a page description language, to a host I/F. A CPU generates a band encoded representation information divided into band units which is stored in a band encoded memory 701. When all image data can not be stored, an available raster memory having maximum size is acquired and a resolution for printing an input data as full raster is determined from the memory size thus acquired. Subsequently, the raster data is compressed reversibly and stored in a compressed band memory 703. If the memory 703 is deficient, a reversible compressed band is decompressed in units of band in a rastering memory 702 and degraded before being stored in a raster memory 704.

Title: Optical measuring method
Inventor: YAMAMOTO AKIO
IPC: G01B11/02
Filed: 1988-12-02
Abstract: PURPOSE:To reduce the measuring error due to the contamination of an optical system by performing binarization on the basis of a threshold value determined at first at the time of actual measurement and re-storing a new threshold value from the output value equal to or more than said threshold value with respect to a light detection element receiving the output equal to or more than the threshold value. CONSTITUTION:The signal outputted from a close contact type image sensor is amplified by a video amplifier. At first, the threshold value (60% of output) to the signal from each of light detection elements is calculated on the basis of the signal at the time of the absence of a plate and stored. Next, the comparison is performed with respect to the signal at the time of the measurement of a plate width by a comparator 1 to binarize said signal and the number of the light detection elements taking the value and '1'-value at that time are counted by counters 1, 2. When these light detection elements are arranged on one row, the lengths thereof are calculated. After a measuring result is outputted to a width operator, a new threshold value is calculated by the same procedure as the previous setting of the threshold value only on the light detection elements by the comparator 1 and re-stored. As mentioned above, by altering the threshold value determined at first to the value corresponding to the lowering of output with the elapse of time, high accuracy can be kept.

Title: Screening method of semiconductor laser
Inventor: SHIMIZU JUNICHI
IPC: H01S5/042
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To dispense with a dynamic characteristics screening process so as to markedly lessen and simplify a screening process and man-hours by a method, wherein a semiconductor laser is carried out through a static method to determine whether it is defective or not at high-speed modulation. SOLUTION: In a semiconductor laser screening process, IL (injection current less light output) characteristic of a semiconductor laser shows a relation between the amount of an injection current and the intensity of an optical output, where IL is the first derivative by an injection current so as to obtain a differential IL(=ΔI/ΔL), and the waveform of a differential IL(=ΔI/ΔL) is utilized. That is, differential waveforms are grouped into three patterns and defined as a differential waveform which is protrudent (a), a differential waveform which decreases monotonically, and a differential waveform which has peak near a threshold. When the differential IL waveform of a semiconductor laser is protrudent on a side, where a drive current is larger than a discontinuous point near a threshold, the semiconductor laser is determined as being nondefective.  Or when the differential IL waveform of a semiconductor laser decreases monotonically on a side, where a drive current is larger than a discontinuous point near an oscillation threshold, the semiconductor laser is determined as being defective. With this setup, a dynamic characteristics screening process, in which a semiconductor laser is screened as being modulated at a speed 2.5 Gb/s or higher can be dispensed with, so that a screening process and man-hours can be markedly simplified and lessened.
