Title: Method for designing printed wiring board
Inventor: ISHIBASHI YOSHINORI
IPC: G06F17/50
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for manpower and shorten design time and enhance design quality by determining bounds within which a specific part is mounted on a printed wiring board, and changing design of a resist pattern by data of an area which needs design changes within the determined bounds. SOLUTION: The position of a mounting plane of a specific part is found as P1=C plane, P2 = S plane, and the coordinates of the specific part is known as P1=X1, Y1, P2=X2, Y2, and an area D1×E1, D2×E2 where solder resist is applied to Via within the bounds to block an opening is recognized. The design of Via under the specific part is changed so as to block Via by making a batch deletion of an instruction for solder resist opening, and Via 17 becomes Via 19, and solder resist is applied. On the other hand, in Via 18 outside the area, the instruction for solder resist opening is left effective, resulting in obtaining a solder resist pattern. This allows design time to be shorten and reliable boards to be designed.

Title: Image forming device
Inventor: SHIMIZU TAMOTSU
IPC: G03G15/09
Filed: 1988-12-26
Abstract: PURPOSE:To make a line picture sharp and to obtain a high density solid image by switching the developing magnetic pole of a magnet and the difference between a surface potential and a developing bias voltage in the non-image part of an electrostatic latent image and vice versa, in response to the operation of an image quality switching means. CONSTITUTION:When a line mode is selected through an image quality mode changeover switch 48, a power source 7 receives a signal from a CPU 49 and sets the grid voltage of an electrifying charger 4 at a high level. Consequently, a photosensitive layer 2 is electrified to 900V, for instance; the image part of the electrostatic latent image part, 900V; and its non-image part <= several tens V. Therefore, no unnecessary toner attaches to obtain a sharp image. Conversely, when a solid mode is selected through the switch 48, the grid voltage of the charger 4 is set at a low level. This level electrifies the layer 2 to 600V. Consequently, the potential difference between the image part of the electrostatic latent image and its non-picture part becomes smaller to raise the density of toner attaching to the image part of the electrostatic latent image part. Thus, a solid image is reproduced at high density without void, etc.

Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To optionally reduce cutting resistance by using a carrying mechanism having a plurality of independent cutters to be separated for moving the fixed positions of the cutters to partially replace the cutters. SOLUTION: A welding burr 2 and first to forth stage cutters 11a to 11d are associatively moved in the longitudinal direction of a square billet 1 to meet each other. In this case, the welding burr 2 generated in the square billet 1 is cut off from one end side in the order of the fourth stage cutter 11d to the first stage cutter 11a. Thus, cutting resistance is reduced. In the first to fourth stage cutters 11a to 11d for cutting the welding burr 2, cutter edges are worn off with an increase in the cutting number, and even cutting of the cutters occur. Thus, a cutter 11 opposed to the square billet 1 is towed by a towing means 13a driven by a motor or the like on a carrier guide 12a and moved, and then fixed.

Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To enable a conductor circuit with less warpages to be formed even though a ceramic green sheet is baked simultaneously by having conductive powder which contains a specified amount or more of Ag powder of specific mean and maximum particle diameter produced by atomization method as a main ingredient. SOLUTION: A conductive paste has conductive powder, containing Ag powder of 50 weight% or more, produced by atomization method the mean particle diameter of the powder is 3 to 10 μm, and maximum particle diameter is 40 μm or less as the main ingredient. Here when the mean particle diameter is less than 3 μm, it is difficult to eliminate warpage, and when the mean particle diameter is larger than 10 μm and the maximum particle diameter is larger than 40 μm, the powder is crushed into foil in making paste, which clogs screens in printing. As a result, the coefficient of contraction of the Ag powder can be made adapted to that of a ceramic green sheet by using the Ag powder in this range. This enables a warpage-free ceramic multilayered circuit board to be formed.
