Filed: 1989-09-28
Abstract: PURPOSE:To execute completely bumpless switching with a short time by giving an intermediate operation value obtained by operating an input signal to be equal to the intermediate operation value to a differential operation means at the time of switching a switch means. CONSTITUTION:The switch means 1 changes over a first signal SA, the load signal of a generator driven by output steam from a boiler, for example, and a second signal SB, a signal corresponding to a main steam flow rate, for example. A pre-processing operation means 7 gives the intermediate operation value Zn-1 obtained by operating the input signal In to be equal to the intermedi ate operation value Zn-1 to the differential operation means 2 at the time of switching the switch means 1. The differential operation means 2 operates the output by using the intermediate operation value Zn-1 given from the differen tial operation means 2 at the time of switching the signals. When two signals are switched, a system comes to a manual operation for a short time. When it comes back to an automatic operation, the output PVn of the differential operation means becomes '0' and the bumpless switching is realized.

Title: Semiconductor integrated circuit
Inventor: NAKAJIMA TAKAHIKO
IPC: H01L21/822
Filed: 1991-10-01
Abstract: PURPOSE:To reduce a power supply impedance of IC as much as possible by forming a power supply passing capacitor as nearer as possible to an IC power supply terminal, that is, on a power supply pad. CONSTITUTION:All electrostatic capacitance is achieved by forming a constitution to hold a ferroelectric material layer 11 with parallel flat electrodes with the adjacent power supply pad 9 of VDD and the power supply pad 10 of VSS. This electrostatic capacitance can be controlled with a shape of power supply pads, a dielectric constant and thickness of ferroelectric material layers, and moreover since this electrostatic capacitance may be formed in parallel in a number as many as the number of power supply pads for the power supply line, necessary electrostatic capacitance can be obtained. An impedance of the power supply line can be reduced by forming such electrostatic capacitances between the power supply pads VDD and VSS and thereby malfunction of IC resulting from external power supply noise can be prevented.
