Filed: 1989-10-02
Abstract: PURPOSE:To produce the easier-to-see sentences by shifting a state where the same character strings are arranged in the same way between the adjacent rows or columns by changing the expressions before and after the same character strings. CONSTITUTION:The prescribed number of same character strings designated by a user are set to a buffer for prescribed number, and two adjacent rows or columns are set to a collation buffer from the head of a document. Then the collation is applied to each character at and after the head of the collation buffer. When the same character strings are detected after the collation, the number of characters of the character strings are compared with the prescribed number of characters. The same character strings are decided when the former number is larger than or equal to the latter number. Then a message is displayed on a display and the same character strings are displayed with inversion. The presence or absence of a character string to be replaced is checked between the same character strings. If the presence of the subject character string is confirmed, a replacement process is carried out by reference to a replacement table. Meanwhile the action mode is switched to a correction mode for the user if the absence of the subject character string is confirmed. These actions are repeated until a document is through.

Title: Operational amplifier
Inventor: SHIBATA TORU
IPC: H03F3/345
Filed: 1991-10-04
Abstract: PURPOSE:To allow the operational amplifier to be affected by the effect of fluctuation of a power supply voltage and of a threshold voltage of a MIS transistor(TR) by adopting a depletion type for the MIS TR constituting a phase compensation circuit and setting a gate electrode and a source electrode to be equi-potential. CONSTITUTION:An N-channel depletion TR is adopted for a MIS TRN6 constituting a phase compensation circuit and a gate electrode and a source electrode of the TRN6 thereof are connected. Thus, a drain-source impedance R6 of the TRN6 is expressed as R6=1/beta6 (-VTD), where beta6 is a gain constant of the TRN6 and VTD is a threshold voltage of the N-channel depletion MIS TR. Thus, even when the frequency at which a zero appears is designed to be infinite or the like, the operational amplifier without affecting this relation by the fluctuation of the power supply voltage and the threshold voltage of the MISTR is obtained.

IPC: C23C14/34
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To always stabilize plasma by controlling the reaction between sputtering atoms and a reactive gas in a short time. SOLUTION: The potential difference is given to the space between a target 3 and a wafer 10 arranged so as to oppose each other at positions far by prescribed intervals in a vessel 2 fed with an inert gas to generate plasma, furthermore, in the case the reacting state between sputtering atoms dispersed into the plasma in the vessel 2 fed with the prescribed reactive gas and the reactive gas is controlled, the luminous intensities with prescribed wavelengths of light to be generated by the luminescence of the sputtering atoms are detected by at least two or more kinds, the average value of the luminous intensities is calculated, and based on the calculated result, the quantity of the reactive gas to be fed is controlled.  In this way, even in the case either luminous intensity remarkably fluctuates by external disturbances, the width of the fluctuation is small since the average value is satisfied, therefore the increse and decrease of the quantity of the reactive gas to be fed is also small, so that the reacting state is controlled in a short time to stabilize the plasma.

IPC: G05F3/18
Filed: 1984-12-06
Abstract: PURPOSE:To prevent the malfunction of a control part at the time when a power source is off, by providing a constant-voltage element between an output of a main power source part and a power source of a part to which power is supplied. CONSTITUTION:A power source circuit is constituted of a main power source part 1, a logic circuit power source part 2, a control part 3 and a part 4 to be controlled. In this case, a constant-voltage element 71 is connected between an output of the main power source part 1 and the part 4 to be controlled. As a result, a power supply voltage of the part to be controlled 4 becomes (an output voltage of the main power source part 1)-(a both-end voltage of the constant-voltage element 71), therefore, the time when the part to be controlled 4 becomes a state impossible for operation after the power source has been turned off can be made shorter than a fall of the control part 3. In this way, it does not occur that the part to be controlled 4 becomes inope rable, and the part 4 to be controlled causes malfunction, before an output signal of the control part 3 becomes indefinite.
