Title: Automatic wiring method
Inventor: HIYOUDO TAKESHI
IPC: H05K3/00
Filed: 1988-10-13
Abstract: PURPOSE:To efficiently perform wiring and to surely obtain a solution by connecting two points with a path of minimum distance in advance, and performing the path so as to evade an obstacle when the path is crossed with the obstacle. CONSTITUTION:A line segment 11 which connects the points (1) and (1') with the minimum distance neglecting the obstacle 10 is found, and the intersection of the line segment 11 and diagonals aa' and bb' is found. In the example, the line segment is crossed with the diagonal aa' at the intersection (c). Next, polygonal lines (1), (1')(12), (1)a'(1')(13) are found by moving the intersection (c) to the positions of endpoints (a) and (a') along a direction of arrow head. When the line segment is crossed with another diagonal, a similar operation is performed on the intersection. Next, the polygonal line 13 with a short side is selected, and a constant interval 14 is generated so as to insert another wiring between the polygonal line and the obstacle 10. In other words, a constant value is added(subtracted) on the X and Y coordinates of the point (a'), and the polygonal line 15 connecting a new point to the points (1) and (1') is found. In such a way, it is possible to find the wiring 15 connecting the points (1) and (1'). Such operation is applied on all pairs of two points to be found, thereby, all wiring can be found.

Title: Planarity adjusting mechanism and planarity measuring apparatus for heating element array
Inventor: HARA DAISUKE
IPC: B41J2/335
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To adjust planarity of a heating element array easily by preventing deformation thereof during printing operation. SOLUTION: Vertical profile of the heating element array in a thermal head is measured by means of a large number of linear gauges arranged side by side and presented on the monitor of a computer. Planarity of the heating element array is adjusted by means of an adjusting mechanism while viewing the monitor. The adjusting mechanism comprises a reference plate 20 for adjustment, an outer adjustinq screw 22 and an inner adjusting screw 23. When the outer adjusting screw 22 screwed to the reference plate 20 for adjustment is turned unilaterally, a radiation fin 16 is pushed downward by the forward end part thereof. The inner adjusting screw 23 penetrates the outer adjusting screw 22 before being screwed to the radiation fin 16. The inner adjusting screw 23 pulls the radiation fin 16 toward the reference plate 20 for adjustment.  Planarity is adjusted by turning the outer adjusting screw 22 in any one direction thereby deforming the heating element array vertically. Since the radiation fin 16 is applied with a pushing force and a pulling force, thermal deformation of the heating element array is prevented during printing operation.

Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of the discharge characteristic by making the thickness of a current collector at a part, where the active substance is arranged to be smaller than the thickness of a part where no active substance is arranged. SOLUTION: In a negative electrode current collector of 90 μm thickness, a copper foil 2 of 30 μm thickness is welded with ultrasonic wave to each side of a part of a copper negative electrode current collector 1 of 10 μm thickness, where no active substance is arranged. The active substance mixture 3 which is the mixture of the carbon material with the binder of polyvinylidene fluoride, is coated on each side of the negative electrode current collector 1 by 70 μm each side. A copper tub terminal 4 (80 μm in thickness) is welded to the copper foil 2 with ultrasonic wave.  Because the part of the negative electrode current collector 1 where no active substance is arranged, is a connection part of the tub terminal 4 to the external part of a battery, and a part where the power concentration is generated, the current collection efficiency of the electrode is improved by increasing the thickness compared with the part of the negative electrode 1, where the active substance is arranged to reduce the electrical resistance.
