摘要： PROBLEM TO BE SOLVED: To cut wirings over a wide laser power range by cutting the wirings without giving a damage to a lower layer of the wirings, by illuminating a laser beam having a pulse width of a specific value or less to a desired position on the wirings of a semiconductor device or high density multilayer wiring board. SOLUTION: A laser beam 2 emitted from a picosecond laser 1 having a pulse width of 1 nsec or less and several mjoule is illuminated to a surface of a work piece 8 such as a semiconductor, a high density multilayer board or the like in the shape for projecting an image of a liquid crystal pattern via a projecting lens 7. Thus, since the beam has a short pulse width of 1 nsec or less, the illumination of the laser pulse is finished before the illuminated wiring is changed caused by heat, and hence no invasion of the beam occurs after removal by the phenomenon. Accordingly, a lower surface of the wirings is not damaged, but a desired position of the wiring can be cut.

摘要： PROBLEM TO BE SOLVED: To attain improvement in environment correspondence from the stage of research and development while facilitating arithmetic processing and display by quantitatively indexing and displaying the environment correspondence degree of research and development. SOLUTION: A factor environment influence coefficient and factor leveling function or the like are determined from a legal specification value or self-specification value and inputted to a database 109 beforehand. A block environment influence coefficient, item environment influence coefficient and full environment influence coefficient are inputted as well. A factor evaluation point is calculated while using the factor environment influence coefficient and factor leveling function, next, a block evaluation point is calculated while using the result and block environment influence coefficient, and an item evaluation point is calculated. Then, a full evaluation point is calculated from the result and full environment influence coefficient. In this case, the result is displayed on a display device 103 and the item, block and element evaluation points are displayed. Thus, not only the environment correspondence degree evaluation point of that research and development theme but also the evaluation point of the same section or any other section and the average evaluation point of all the sections are found and displayed on the screen of an output device 104.

摘要： PROBLEM TO BE SOLVED: To improve wiring pattern generating efficiency by suppressing delaying defect and unwiring at the wiring designing system of a printed substrate. SOLUTION: In order to decide a wiring pattern generating order, the detour ratio of all the nets is calculated to rearrange in the increasing order of the detour ratio (steps 1 to 3). In addition, within the net group of the same detour ratio, a net is sorted in the increasing order of a delay restricting value (step 4). According to a wiring pattern generating order decided in this manner, a wiring pattern is generated (step 5) to suppress delaying defect and unwiring to improve the efficiency of wiring designing processing.

摘要： PROBLEM TO BE SOLVED: To effectively eliminate a noise without using a noise absorbing material in a noise eliminating splitter arranged in an exhaust duct and so on, by extensively setting the rate of hole area of each noise absorbing hole against the surface area of each noise eliminating splitter main body by a predetermined rate in an intermediate part against an exhaust upstream part and an exhaust downstream part. SOLUTION: A noise eliminator comprises a plurality of noise eliminating splitters 4. Each noise eliminating splitter 4 is formed of a noise eliminating splitter main body 5, and partitioning walls 7 by which the inside of the main body 5 is partitioned into a plurality of noise eliminating chambers 6, and many noise absorbing holes 10, 11 are formed on the surfaces of both side walls 8 of the main body 5. The rates of hole areas of respective noise absorbing holes 10, 11 are set to be approximately 30% in an intermediate part 12, and approximately 3% in an upstream part 13 and a downstream part 14. The noise eliminator 1 is made to serve as both an extended chamber type noise eliminating splitters in which the passage cross sectional area of an acoustic wave is changed and resonance absorption noise eliminating splitters by which the acoustic wave is absorbed and canceled, therefore, a noise can be enough eliminated without filling a noise absorbing material into the inside of the main body 5.

摘要： PURPOSE:To omit an unnecessary decision process and speedily make a screen display by storing state of surface data which are issued last time, and dynamically changing the decision process order of a display area inside/outside decision process and a visible surface obverse reverse decision process on the basis of the state of the last issued surface data. CONSTITUTION:As for characteristics of surface data constituting a three- dimensional figure, when the last issued surface data 42a are outside a display area 41, the possibility that next issued surface data 2b are outside the display area 41 is high. When the visible surface 43a of the last issued surface data becomes a reverse surface, the possibility that the next issued surface data 43b becomes the reverse surface is high. For the purpose, unnecessary decision processes are omitted according to the state of the last issued surface data to reduce unnecessary nondisplay states and coordinate converting processes, normal converting processes, etc., accompanying them, and thus the processing speed of the nondisplay process of the figure is speeded up to make it possible to speed up the image display process.
