Title: Semiconductor integrated circuit
Inventor: HAYASHI YUTAKA
IPC: H01L27/08
Filed: 1985-06-21
Abstract: PURPOSE:To prevent erroneous operations due to fluctuation in potential, by forming the thickness of at least a part of a power source wiring in the direction of the vertical cross section thicker than an internal wiring for signals. CONSTITUTION:On the surface of an integrated circuit immediately before an Al wiring process, Al is evaporated in the entire surface. Thereafter, photoresist is applied. A bright mask is prepared for a high potential wiring part or a ground wiring part. A dark mask is prepared for the other part. The photoresist is exposed through the masks. By the exposure, the photoresist covering the high potential wiring part or the ground wiring part is sensitized and hardened. When the photoresist, which is not hardened, is removed, the Al, which covers the part other than the high potential or ground wiring part is exposed. Then, Al is evaporated on the entire surface of the integrated circuit again. Photoresist is applied on the entire surface. Therefore, the impedance of a power feeding line is strikingly reduced. Fluctuation in power source potential due to a large current is eliminated. Thus erroneous operations in the semiconductor can be avoided. Noises generated at an output port and the like can be suppressed.

Filed: 1979-10-24
Abstract: PURPOSE: To improve a starting method of a single shaft gas turbine in a pump set of the gas turbine to reduce powder necessary for a pump in low speed.  
     CONSTITUTION: Whan a pump 13 is started, its rotational speed is increased under idling condition, i.e. substantially no-load condition of the pump until output generated by a single spindle gas turbine (not shown) for driving the pump 13 becomes larger than powder necessary for rising of the pump 13. Then, an intake valve 12 is operated to close a path to a drain pipe 17, and pumped-up liquid 11 fully opens a path leading to the pump 13 and begins to be supplied. To minimize impact of the liquid 11 to the pump 13 at that time, a main discharge valve 14 is closed and only a bypass valve 15 is set to the minimum allowable opening. Next, the speed of the pump is raised from this condition to a rated rotational speed and the main discharge valve 14 is adjustable operated to provide a required discharge amount. The pumped-up liquid thus discharged is introduced through a discharge pipe 18 into a nozzle or the like for work.
