IPC: G06F17/50
Filed: 1997-05-23
Abstract: PROBLEM TO BE SOLVED: To determine a path which connects two points together bypassing an obstacle by forming a path which extends from a start point to an end point by using a bypass which extends from a 1st point to a 2nd point on the straight line connecting the start and end points and bypasses the obstacle on the straight line. SOLUTION: A CPU sets a retrieval range E0 (range which has a straight line L set vertically and horizontally and is expanded by a clearance value δ5) containing the straight line connecting the start point d1 and end point d2, and retrieves obstacles A and B on a screen overlapping with the retrieval range E0 and specifies, for example, the obstacle A as an object to be processed. The CPU finds an offset contour line (position at a distance of clearance δfrom the contour line of the obstacle A) AO surrounding the specified object A and finds the intersections d3 and d4 of the straight line L and offset contour line AO. The CPU traces the offset contour line AO clockwise and counterclockwise from the intersection d3 to decide a short path among paths reaching the intersection d4 as a bypass.

Title: Method for stabilizing laser wavelength
Inventor: SHIRASAKI MASATAKA
IPC: H01S3/131
Filed: 1983-07-26
Abstract: PURPOSE:To stabilize the output wavelength with a high accuracy by a method wherein two beams of different wavelengths separated from a laser beam of a single wavelength are inputted to a resonator, which is then constructed so as to compare the outputs and then to feed them back to the laser. CONSTITUTION:The beam of the single wavelength lambda emitted from the laser 1 is separated into the two beams of close wavelengths lambda1 and lambda2 by means of a separating element 2, which beams are then inputted to the Fabry-Perot resonator 3. The two outputs obtained are detected by a photo detector 4, compared by a comparator 5, and fed back to the laser 1. The beams of wavelengths lambda1 and lambda2 outputted from the resonator 3 vary at the same width with the variation of the laser wavelength lambda; while one output increases, and the other decreases. Thus, the wavelength can be stabilized by the feedback of the difference of these outputs to the laser 1.

Thus, its correction value is led from the confirming data by the theoretical calculation and the experiment, the semi-fixed resistance VR is varied to adjust the control voltage VCONT. Thus, malfunction is prevented by inexpensive components, circuits and slight adjustment.

Abstract: PURPOSE:To obtain a masking arithmetic unit that can save the desired capacity of a table memory by using the output of a computing element as the read address of the table memory and calculating the secondary member of an arithmetic formula with reference to the table memory. CONSTITUTION:The table memories 1-3 obtain Y1=a1R+alpha4R<2>, Y2=a2G+alpha5G<2> and Y3=a3B+alpha6B<2> at every color. The subtractors 4-6 obtain the subtraction values R-G, G-B and B-R between two colors. Then the absolute value circuits 7-9 obtain the absolute values ¦R-G¦, ¦G-B¦ and ¦B-R¦ for each subtraction value. These subtraction outputs are used as the read addresses to obtain Y4=alpha7¦R-G¦<2>, Y5=alpha8¦G-B¦<2> and Y6=alpha9¦B-R¦<2> from table memories 10-12 respectively. Then the outputs Y1-Y3 obtained from memories 1-3 are added with the outputs Y4-Y6 obtained from memories 10-12 by an adder 10 to obtain an output Y=Y1+Y2+Y3+Y4+Y5+Y6. Thus it is possible to save the capacity of those table memories and to attain the accurate color reproducibility via an inexpensive arithmetic unit.
