Granted: 1991-10-26
Abstract: A tantalum oxide (Ta2O5) silm is formed by ionizing an  argon gas to be collided with negative-electrificated target, chemically reacting a target atom with an oxygen gas to  produce  a  reaction product, and  adhering  the  product  on  the  substrate  by  the sputtering. The oxidation ratio  of  the  film  is  controlled  by gradually decreasing the flow rate  of  the  argon  gas  and  then increasing the flow rate of the oxygen gas. The film  has  a  good uniformity and reproductibility.

Abstract: If there are many areas having continuous white  pixels,  all the central  pixels  are  replaced  with  "0"  up  to  the  point immediately before the termination of the run of the white pixels, and an intermediate computation is  skipped.  If  there  are  many areas having continuous black pixels, an intermediate  computation for the run length of the black pixels is not carried out. If  the central pixel is white, and if at least three of  the  surrounding four pixels are black, the central pixel is recognized as a  hole, and the hole is removed. Then a value C other than a mask matching is defined to find the outer contour and  to  preserve  thin  line components.

Title: Flow detecting system
Inventor: WHEATON ROGER BOWDEN

Abstract: PURPOSE: A flow detecting device is provided to prevent waste of water from leak, and to cut down cost by sensing leak of a water pipe and by shutting off flow with a control valve in detecting leak. CONSTITUTION: A flow detecting device for a water pipe(10) is composed of a flow detector(11) measuring flow of fluid through the pipe, and having a sensor element(12) transferring pulse according to the flow rate of fluid flowing through the water pipe; a control circuit(13) receiving the pulse from the sensor element by connecting to the flow detector, and outputting signals in detecting leakage; a solenoid(14) intermittently operating and closing a control valve(15); and the control valve shutting off flow through the water pipe in outputting signals from the alarm or the control circuit operating according to signals. The control circuit records the detected flow rate less than the predetermined level, and outputs signals to indicate leakage of fluid to a user.

Abstract: a resistor array having the 2"-1 number of unit resistors connected in series between a first terminal and a 2"th node; a switching circuit for selectively connecting the first terminal, the respective nodes between the 2"-1 number of unit resistors and the 2"th node to a second terminal; and a programmable switching control circuit supplying n pairs of complementary switching control signals to the switching circuit in response to n bit resistance value control signal in a control mode, and having a program for fixing n pairs of complementary switching control signals responding to controlled resistance values. The resistance value between the first terminal and the second terminal is controlled to 2" step. The variable resistor can exactly control the resistance value of a semiconductor integrated circuit.
