Abstract: A semiconductor integrated circuit effectively makes use of wiring channels of wiring formed by a damascene method. When first cells are used, since the M1 power source lines are laid out at positions spaced away from a boundary between the cells, the power source lines are not combined in laying out a semiconductor integrated circuit. As a result, the width of the power source lines is not changed. Accordingly, an interval between the line and a line which is arranged close to the line, determined in response to a line width of the lines, can satisfy a design rule; and, hence, the reduction of the wiring channels can be obviated, whereby the supply rate of the wiring channels can be enhanced, and, further, the integrity of a semiconductor chip can be enhanced.

Abstract: It is intended to ensure the connectability of wiring lines in a semiconductor device having terminals or reservoirs. Plural terminals of a cell which constitutes the semiconductor device are each formed in a shape having a length corresponding to two or more lattice points. The terminals are arranged so that one or more lattice points are interposed between adjacent terminals. Among the terminals, as to the terminals adjacent to each other in their shorter direction, it is allowable for them to partially overlap each other in their shorter direction. In this state, second-layer wiring lines are connected to the terminals via through holes, whereby reservoirs can be generated at the terminals respectively.

This medical facility introduction system is characterized in that a communication terminal establishes communication with the host computer 10, an appropriate medical facility is selected, and that result is sent to communication terminal.

Abstract: An apparatus for forming an annular member simply with high accuracy, for example, a side tread and bead filler having a height in the radial direction comparatively larger than its thickness as a constituent member of a tire. A material, for example, a soft and fragile raw rubber at a high temperature is directly extruded through a mouthpiece of an extruder onto a rotating disc-like lower mold so as to adhere onto it. The lower mold is able dividable into plural lower mold segments. An arcuately curved extruded material is formed on the lower mold in this manner. The extruded material is not deformed during being cooled because it is strongly restrained by the receiving surface of the lower mold on which the material adheres. The extruded material is then cut along the divided lines of the lower mold segments. Lower mold segments thus having arcuately extruded materials, respectively, are then transferred to a restoration position and gathered together to form the original lower mold.
